Gas pressure regulators
Control of a hydraulic operating mode of system of gas distribution is exercised by means of gas pressure regulators which automatically support constant pressure in a point of selection of an impulse irrespective of intensity of consumption of gas. At regulation of pressure there is a decrease in initial more high pressure on final lower. It is reached by automatic change of extent of opening of drosseliruyushchy body of the regulator owing to what the hydraulic resistance to the passing gas stream automatically changes.
Depending on the supported pressure (an arrangement of a controlled point in the gas pipeline) regulators of pressure of gas divide into gas pressure regulators to themselves and after themselves. In GRP (GRU) use only gas pressure regulators after themselves.
The automatic regulator of pressure of gas consists of the executive mechanism and regulator. The main part of the executive mechanism is the sensitive element which compares signals of the control point adjustment and the current value of adjustable pressure. The executive mechanism will transform a command signal to the regulating influence and to the corresponding movement of a mobile part of regulator due to energy of a working environment (it can be energy of the gas passing through the gas pressure regulator or energy of the environment from an external source electric, compressed air, hydraulic).
If the permutable effort developed by a sensitive element of the regulator of pressure of gas rather big, then he carries out functions of management of regulator. Such regulators of pressure of gas are called regulators of pressure of direct action. For achievement of necessary accuracy of regulation and increase in permutable effort between a sensitive element and regulator the amplifier the command device can be installed (sometimes called by the pilot). The measuring instrument operates the amplifier in whom due to foreign influence (energy of a working environment) the effort which is transferred to regulator is created.
As in regulators of regulators of pressure there is a gas drosselirovaniye, them sometimes call drosseliruyushchy.
Because the regulator of pressure of gas is intended for maintenance of constant pressure in the set point of gas network, it is always necessary to consider system of automatic control in general "the regulator and subject to regulation (gas network)". The principle of operation of regulators of pressure of gas is based on regulation on a deviation of adjustable pressure. The difference between demanded and actual values of adjustable pressure is called a mismatch. It can arise owing to various vozbuzhdeniye or in gas network because of a difference between inflow of gas to it and gas offtake, or because of change entrance (to the regulator) gas pressure.
The correct selection of the regulator of pressure of gas has to provide stability of system the regulator - gas network, i.e. its ability to come back to an initial state after the indignation termination.

Control of a hydraulic operating mode of system of gas distribution is exercised by means of pressure regulators which automatically support constant pressure in a point of selection of an impulse irrespective of intensity of consumption of gas. At regulation of pressure there is a decrease in initial — higher — pressure on final — lower. It is reached by automatic change of extent of opening of drosseliruyushchy body of the regulator owing to what the hydraulic resistance to the passing gas stream automatically changes.
Depending on the supported pressure (an arrangement of a controlled point in the gas pipeline) regulators of pressure divide into regulators "to" and "after themselves". In GRP (GRU) use only regulators "after themselves".
The automatic regulator of pressure consists of the executive mechanism and regulator. The main part of the executive mechanism is the sensitive element which compares signals of the control point adjustment and the current value of adjustable pressure. The executive mechanism will transform a command signal to the regulating influence and to the corresponding movement of a mobile part of regulator due to energy of a working environment (it can be energy of the gas passing through the regulator or energy of the environment from an external source — electric, compressed air, hydraulic).

Because the regulator of pressure of gas is intended for maintenance of constant pressure in the set point of gas network, it is always necessary to consider system of automatic control in general — "the regulator and subject to regulation (gas network)". The principle of operation of regulators of pressure of gas is based on regulation on a deviation of adjustable pressure. The difference between demanded and actual values of adjustable pressure is called a mismatch. It can arise owing to various vozbuzhdeniye — or in gas network because of a difference between inflow of gas to it and gas offtake, or because of change entrance (to the regulator) gas pressure.
The correct selection of the regulator of pressure has to provide stability of the "regulator-gas network" system, i.e. its ability to come back to an initial state after the indignation termination.
Proceeding from the law of the regulation which is been the basis for work, regulators of pressure happen astatic, static and izodromny.
Like regulators gained the greatest distribution in systems of gas distribution of the two first.
In astatic regulators the sensitive element (membrane) is affected by constant force from freight 2. The active (counteracting) force is strengthening which is perceived by a membrane from the output pressure of P2. At increase in gas offtake from network 4 P2 pressure will decrease, the balance of forces will be broken, the membrane will go down and the regulator will open.
Such regulators after indignation lead adjustable pressure to a preset value irrespective of the size of loading and position of regulator. Balance of system can come only at a preset value of adjustable pressure, and the regulator can hold any position. It is necessary to use such regulators on networks with big self-alignment, for example, in gas networks of low pressure enough high-capacity.
The side play, friction in joints can lead to the fact that regulation will become unstable. For stabilization of process enter rigid feedback into the regulator. Such regulators are called static. At static regulation equilibrium value of adjustable pressure always differs from the set size, and only at a rated load the actual value becomes equal nominal. Static regulators are characterized by unevenness.
In the regulator freight is replaced with a spring — the stabilizing device. The effort developed by a spring in proportion to its deformation. When the membrane is in extreme top situation (the regulator is closed), the spring gets the greatest extent of compression and P2 — maximum. At completely open regulator P2 value decreases to minimum. The static characteristic of regulators is chosen flat unevenness of the regulator was small, at the same time process of regulation becomes fading.
The Izodromny regulator (with elastic feedback) at a deviation of adjustable pressure of P2 at first will move regulator at a size proportional to deviation size, but if at the same time pressure of P2 does not come to a preset value, then the regulator will move until pressure of P2 does not reach a preset value.
The terms used for the characteristic of operation of regulators of pressure of RDGK RDGD RD RDU RDNK RDSK RDBK RDG RDUK gas.
Static mistake — the deviation of adjustable pressure from set at the set mode, is also called unevenness of regulation.
Dynamic mistake — the maximum deviation of pressure during a transition period from one mode to another.
Valve stroke — distance to which the valve from a saddle moves.
Control range — a difference between the top and lower limits of pressure between which setup of the regulator can be carried out.
The top limit of control of pressure — the maximum output pressure for which the regulator can be ready.
Regulation zone — a difference between adjustable pressure at 10% and 90% of the maximum expense.
Tolerance zone — the difference of adjustable pressure necessary for change of the direction of the movement of regulator.
Proportionality zone — the change of adjustable pressure necessary for movement of regulator (valve) of value of its nominal (full) course.
Conditional capacity of Kv — the size equal to a consumption of water with a density of 1 g/cm ³ (1000 kg/m ³) in cubic meters an hour via the regulator at a nominal (full) valve stroke and pressure difference of 0,1 MPas (1 kg/cm ²).
Relative leakage — the relation of the maximum value of a leakage of water through a lock of regulator at pressure difference on 0,1 MPas and the conditional capacity of Kv.
Designs of regulators of pressure of gas have to meet the following requirements:
• the zone of proportionality should not exceed 20% of the top limit of control of output pressure for the combined regulators and regulators of balloon installations and 10% for all other regulators;
• the zone of tolerance should not be more than 2,5% of the top limit of control of output pressure;
• time constant (time of transition process of regulation at sharp changes of a consumption of gas or entrance pressure) should not exceed 60 pages.
Basic elements of the regulating (drosseliruyushchy) bodies are locks. They can be one saddle, two saddle, diaphragm and hose, crane and zaslonochny.
In city systems of gas supply generally use regulators about one - and two saddle locks, is more rare — with zaslonochny and hose.
One saddle and two saddle locks can be made as with rigid consolidation (metal on metal), and with elastic (laying of maslobenzostoyky rubber, skin, a ftoroplast, etc.). Such locks consist of a saddle and the valve. The fact that they easily provide tightness of consolidation is of one saddle locks.
However valves of one saddle locks are not unloaded since the difference of entrance and output pressure acts on them.
In gas pressure regulators widely use dish-shaped flat valves with elastic consolidation. The full speed of the flat valve at which regulation process will be carried out, is defined from equality of a side surface of the cylinder with diameter of a saddle of dc, height of raising of the valve
h and areas of a saddle of the valve: (πdс ²)/4=πdсh, h=0.25dc
For an example: the regulator with a diameter of saddle of 4 mm has a full speed of the valve of 1 mm. Nearly height of raising of the flat dish-shaped valve is accepted by (0,3+0,4) dc. Further raising of the valve does not affect its capacity. At change of a form of a lock the valve stroke can be increased.
Two saddle locks under the same conditions have considerably bigger capacity owing to the bigger total area of the section through passage of saddles. These valves are unloaded, however in the absence of a gas consumption they do not provide tightness that is explained by difficulty of landing of a lock at the same time on two planes. Two saddle regulators use more often in regulators with a constant power source.
Zaslonochny locks apply usually in GRP with heavy expenses of gas (for example, combined heat and power plant) and use as regulator of regulators of indirect action with a foreign power source.
In the regulators of pressure of gas installed in GRP as a sensitive element and at the same time the drive generally use membranes (flat and corrugated).
The flat membrane represents a round flat plate from elastic material. The membrane is clamped between flanges of the top and lower membrane covers. The central part of a membrane on both sides is clamped between two round metal disks (blooming). Hard drives increase permutable force and reduce unevenness of regulation.
The permutable effort developed by a membrane depends on the size of the so-called effective area of a membrane. It changes depending on a membrane deflection. The permutable effort is determined by a formula:
N = cFP,
where with — coefficient of activity of a membrane; F — the area of a membrane (in a projection to the plane of its seal); P — the excessive pressure of a working environment; cF — the active area of a membrane.
Dependence of coefficient of activity of a membrane with from the size of its relative deflection Δh
Because at various deflection of a membrane of value of coefficient of activity change, also the permutable effort of a membrane changes. It creates unevenness of regulation. Therefore for a flat membrane with two blooming metal disks (diameter 0,8 diameters of a membrane) the site on a curve at change is optimum Δh from 0 to 1/2, respectively, a coefficient of activity of c changes ranging from 1 to 2/3 (~ from 100 to 67%).
Diameter of blooming disks can be chosen no more than 0,8 diameters of a membrane for ensuring necessary mobility of the membrane drive.
Basic principles of the choice of regulators
RDGK RDGD OF RD OF RDU OF RDNK OF RDSK OF RDBK OF RDG OF RDUK
The choice of regulators of pressure of gas needs to be made taking into account the following factors:
• type of a subject to regulation;
• the maximum and minimum required gas consumption;
• maximum and minimum entrance pressure;
• maximum and minimum output pressure;
• regulation accuracy (as much as possible tolerance of adjustable pressure and time of transition process of regulation);
• need of full tightness when closing the regulator;
• acoustic requirements to operation of regulators with high entrance pressures and heavy expenses of gas.
The main requirement at selection of the regulator of pressure is ensuring stability of its work on all possible modes that it is the simplest to achieve a right choice of the regulator for this or that object. (With gas offtake at the end of the gas pipeline) it is necessary to use static regulators of direct action to the deadlock gas pipeline. In case of heavy expenses of gas — indirect action. For ring and extensive gas networks, considering their ability to self-alignment, in principle it is possible to use any types of regulators, but as these networks have usually heavy settlement expenses, it is better to use astatic regulators of indirect action (with the pilot). These regulators allow to support more precisely pressure after themselves.
Unevenness of regulation at static regulators of pressure of direct action ± (0–20) %, static indirect action (with the pilot) and astatic ± (5–10) %.
At connection to networks of high pressure in which pressure has considerable fluctuations, and also considering almost existing designs of regulators, it can turn out that one-stage pressure decrease is not applicable. In this case it is necessary or to choose the two-level regulator of pressure, or to apply two-level reduction at which the first regulator pressure decreases to intermediate value, and the second — to necessary with high precision.
At the choice of the regulator of pressure it is necessary to consider the phenomena connected with noise of the working regulator. Emergence of noise is caused by gasdynamic oscillatory processes in throttle bodies and walls of regulators. At coincidence of frequency of fluctuations amplitude of fluctuations of the valve can sharply increase that will result in wear and destruction of the valve, strong vibration of the regulator. The most effective method of decrease in amplitudes of fluctuations — installation of a quencher of noise (the punched branch pipe) right after gas reduction.
Capacity of regulators of pressure is usually determined by analogy with the expiration of gas through the narrowed nozzle or a nozzle of constant section, including process adiabatic. With a constant entrance pressure of P1 the speed of the expiration and a volume expense grow with reduction of counter-pressure (output pressure) of P2 only before achievement of the relation of P2/P1 of the value defined for this gas which call critical (P2 and P1 — absolute pressure).
For natural gas with K=1,31 adiabatic curve indicator the critical relation can be accepted equal 0,5. That is in pressure regulator which supports low pressure of 2000 Pas (200 mm w.g.), with an entrance excessive pressure in 0,1 MPas and more there comes the critical mode of the expiration of gas. At the same time the speed of the gas passing through a saddle is constant and equal to the sound speed in this gas reached at the critical relation of pressure.
The volume consumption of gas under operating conditions remains invariable and at further pressure decline of P2 and increase in P1. However at the same time the mass consumption of gas, and also the volume expense brought to normal physical conditions changes.
At to the critical mode of the expiration capacity is defined by square dependence of a difference of entrance and output pressure (pressure difference) ΔР = P1-P2. At the critical and supercritical modes capacity depends only on entrance pressure and is directly proportional to it.
Pressure regulator capacity with one saddle lock can be determined on a formula:
Q0=1595φαP1fс√1/ρ0,
where Q0 — a gas consumption via the regulator, m ³ / h (at P =0,1013 MPas, °C t=0); φ — the coefficient depending for this gas on P2/P1 α — expense coefficient (it is brought in a technical characteristic of the regulator); fc — the area of a saddle, cm ² (if the rod of the valve passes through a saddle, then the area of a saddle should be counted minus rod cross-sectional area); P1, P2 — absolute pressure, MPa; ρ0 — density of gas, kg/m ³ (at P =0,1013 MPas, °C t=0).
Having accepted density of natural gas at N at. equal 0,73 kg/m ³, we will receive:
Q=1866φαP1fс
At a temperature of gas of t1= +20 °C the error of a formula will make 3,5%.
The choice of the regulator is made from a condition that its capacity has to be 15-20% more than the maximum hour consumption of gas the consumer. It means that the regulator will be loaded at the maximum gas consumption no more, than for 80%, and at the minimum gas consumption — not less, than for 10%. If this condition is not satisfied, then at the maximum gas offtake the regulator will be completely open and will not be able to perform regulation functions. Regulation is provided only when the regulator and the executive mechanism are in a mobile state. At decrease in gas offtake below limit there can be self-oscillations (pulsations, vibrations) the valve.
The following types of regulators of pressure are most widespread in systems of gas distribution (by the form loadings): regulators of direct action with spring and lever and spring loadings and regulators of indirect action with the command device (pilot).
Schematic diagram of the regulator of the first group. It is possible to carry RDGD-20 and RDSK-50 regulators in which the effort of a working membrane is transferred directly to the valve which is on a rod and fixed in the center of a membrane to them. For unloading of the valve from influence of entrance pressure the additional unloading membrane is used.
The second group is pilotless RD-32M, RD-50M, RDNK-400 regulators. Existence of lever system of transfer of effort from a working membrane to the adjusting valve is characteristic of them. Due to distinction in lengths of shoulders of the cranked lever force of influence of entrance pressure upon the regulator valve decreases. The effort of the membrane drive to the valve at the same time increases that provides higher condensing effort to the valve. For RD-32M the ratio of shoulders of the lever is equal to 6.
At pilotless regulators of the first and second groups body of control of adjustable output pressure is the nastoyechny spring influencing a working membrane.
The limited sizes of a spring and membrane define the following features:
• narrow range of output adjustable pressure which size is defined by parameters of a nastoyechny spring;
• "inclined" account characteristic. It means that with increase in a consumption of gas via the regulator from 0 to 100% output pressure in a certain ratio for each type of the regulator decreases;
• capacity of these regulators is small.
The third group of regulators — RDUK2, RDBK1, RDG devices. Their characteristic — existence of the regulator of management (pilot). Process of regulation is defined by interaction of output pressure upon a working membrane, strengths of the so-called managing director of pressure given from the pilot in under membrane space, freight of mobile parts, forces of friction in connections.
Gas of entrance pressure arrives in the pilot. The pilot supports constant pressure under a working membrane of the regulator. On the pulse pipeline gas of output pressure arrives on a membrane. Through a throttle excess of gas after the pilot is constantly dumped.
Setup of regulators for the required output pressure is made by change of effort of compression of an adjusting spring of the 11th pilot, and also opening or closing of the section through passage of adjustable throttles 6 and 7. Under a membrane cavity of the pilot it is reported with the atmosphere.
If Rvykh decreased, then also pressure over a working membrane will decrease, the valve 4 together with a membrane rises, the gas consumption via the regulator increases, Rvykh increases up to a preset value again.
Pilot regulators have rather wide intervals of entrance and output pressure and capacity. These factors are provided with impact on a working membrane of the regulator under the membrane managing director of pressure created by the pilot instead of direct impact of a nastoyechny spring on a membrane.
In comparison with spring regulators of direct action, pilot have the following advantages:
• possibility of providing enough wide intervals of output adjustable pressure of 0,01-0,06 MPas and 0,06-0,6 MPas;
• ensuring rather big capacity;
• an opportunity in some cases change-over of regulators on working parameters without interruption in supply of gas to consumers.
At reduction of a consumption of gas via the regulator, and also at increase in pressure on an entrance to the regulator often there are not fading sharp fluctuations of output pressure, so-called "rolling". The valve of the regulator is in the first case at small height from a saddle and even small movements of the valve lead to notable change of an expense. In the second case the increased entrance pressure presses the valve to a saddle and there are fluctuations of the valve.
Existence in close proximity to an entrance to the regulator of shutoff valves, measuring throttle washers, narrowings or expansions of the gas pipeline, sharp turns of the gas pipeline can be the reasons of "rolling" of output pressure.
These reasons result in instability of a gas stream on an entrance to the regulator. The unstable stream of gas influences directly a plate of the regulator valve.
"Rolling" of output pressure can be caused:
• insufficiently careful control of an operating mode adjustable throttles;
• the choice of the place of selection of an impulse of output pressure in such point of the gas pipeline where the stream of gas has unstable parameters;
• existence of sharp narrowings of the pulse pipeline between the regulator and the output gas pipeline;
• low-quality insert of the pulse gas pipeline in a wall of the output gas pipeline. The cut pulse pipeline should not act in the output gas pipeline, otherwise there will be a distortion of the selected impulse of output pressure;
• defects of separate knots of the regulator:
- adjusting spring of the pilot not a zatortsovana;
- the coupling knot of a membrane of the pilot is established not on the center;
- too "soft" spring of the pilot;
- the increased gap between a rod of the valve of the pilot and the plug;
- uneven surface of soft consolidation of the valve of the pilot;
- the pilot's valve unevenly on the plane approaches a saddle edge;
- defects of a basic plate of a spring of the pilot;
- the course of a rod of the valve of the pilot does not meet standard.
Summary table of technical characteristics of regulators of pressure of gas
Characteristics of the regulators of pressure of gas intended for reduction of high or average pressure on low, automatic stabilization of output pressure at the established level irrespective of changes of entrance pressure and an expense, automatic shutdown of supply of gas at emergency increase or decrease in output pressure out of limits of the admissible established values are provided in the table.

Valve safety.
Safety valves it is fittings opened in an operational state intended for automatic interruption in supply not of aggressive hydrocarbonic gases to consumers in extraordinary and emergencies.
At excessive increase in pressure of gas tightness violation, leak of gas in connections of gas pipelines and fittings, failure of kontrolnoizmeritelny devices are possible a flame separation at torches and emergence in the working volume of the gas-using equipment of vzryvopasny mix. Considerable pressure decline of gas can lead to a flame proskok in a torch or to blackout of a flame that at not shutdown of supply of gas will cause formation of explosive air-gas mix in fire chambers and gas pipelines of units and in rooms of the installed gas buildings.
For prevention of inadmissible increase or pressure decline in GRP (GRPSh) install the high-speed safety PZK (PTDCs) locking valves and the safety waste valves (SWV).
PZK (PTDCs) are intended for automatic interruption in supply of gas to consumers in case of increase or pressure decline over the set limits, establish them after pressure regulators. PZK work in "emergency situations" therefore their spontaneous inclusion is inadmissible. After operation of PZK (PTDC) it is necessary to find and eliminate malfunctions, and also to be convinced that in front of all gas-using devices and units locking devices are closed only after that it is possible in manual to cock PZK (PTDC).
The PSK valve are intended for restriction of pressure by dumping of gas into the atmosphere up to the established size at increase in pressure in network over an admissible limit.
After decrease in controlled pressure to a preset value of PSK it has to be closed hermetically.
In the presence of a flowmeter (the gas counter) of PSK it is necessary to establish after the counter.
For GRPSh it is allowed to take out PSK out of case limits.
Summary table of technical characteristics of safety locking valves
In this table parameters and characteristics of valves of the safety and locking, intended for automatic interruption in supply nonaggressive hydrocarbonic gases are specified to consumers at increase or decrease in controlled pressure of gas over the set limits.

VALVE THERMOLOCKING KTZ
KTZ-15... 50 muftovy (0,6 MPas)
KTZ-50... 500 flange (1.6 MPas)
The thermolocking valve is intended for automatic overlapping of the gas pipeline at fire emergence.
It is used on gas pipelines of household and industrial function.
PRINCIPLE OF WORK
The valve thermolocking consists of the case in which the locking element in the sprung state withheld in open situation by a thermosensitive element is installed.
At achievement of temperature to the room it is above 90 °C, the element holding the locking mechanism is released and blocks a gas stream.
The valve is the device of single operation.

The gas filter — the device for purification of pipeline gas of dust, a rust, resinous substances and other firm particles. Purification of gas allows to increase tightness of locking devices, and also to increase between-repairs time of operation of these devices due to reduction of wear of the condensing surfaces. At the same time wear decreases and the accuracy of work of flowmeters (counters and measuring diaphragms), especially sensitive to an erosion increases. The choice of filters and their qualified operation are one of the major actions for ensuring functioning of system of gas supply.
In the direction of gas flow through the filtering element all gas filters can be divided on direct-flow and rotary, on design — on linear and angular, on material of the case and a method of its production — on pig-iron (or aluminum) cast and steel welded.
During the developing and the choice of filters the filtering material which has to be chemically inert to gas is especially important, provide the required extent of cleaning and not collapse under the influence of a working environment and in the course of periodic cleaning of the filter.
On the filtering material serially released filters are subdivided on mesh and hair. In mesh use the wattled metal gauze, and in hair — the cartridges filled by kapron thread (or the pressed horsehair) and impregnated with vistsinovy oil.
Mesh filters, especially two-layer, differ in the raised subtlety and intensity of cleaning. In use, in process of a grid contamination, the filtering subtlety at simultaneous reduction of capacity of the filter raises.
At hair filters, on the contrary, in use the filtering ability decreases due to ablation of particles of the filtering material a stream of gas and at periodic cleaning with stirring.
For providing sufficient extent of purification of gas without ablation of firm particles and the filtering material the speed of a gas stream is limited and characterized by the most admissible pressure difference on a grid or the cartridge of the filter.
The filter of FG16-50 gas with the pressure difference indicator (PDI)
For mesh filters the most admissible pressure difference should not exceed 5000 Pas, for hair — 10000 Pas. In the filter prior to operation or after cleaning and washing this difference has to make for mesh filters 2000 — 2500 Pas, and for hair — 4000-5000 Pas. Unions for connection of devices by means of which pressure drop size on the filtering element is defined are provided in a design of filters. GOST 54960-2012 regulates extent of cleaning with the filtering element no more than 80 microns.
