Gas control point of cupboard GRPSh-01-U1 is one of the houses which are most demanded in systems of gas supply and small residential districts. The RDNK-U regulator is used. One-filar with baypasy.
The GRPSh-01-U1 points are intended for reduction of high or average pressure on demanded, for automatic maintenance of the set output pressure irrespective of change of an expense and entrance pressure, automatic shutdown of supply of gas at emergency increase or decrease in output pressure from admissible preset values, cleaning of mechanical impurity of the gas delivered in accordance with GOST 5542-87. Can be completed with gas metering stations and systems of telemetry.
Are a part of point:
— filtration knot;
— line of reduction of pressure of gas;
— bypass line, baypas.
Principle of work: Gas on the entrance pipeline via the entrance crane and the filter arrives to the gas pressure regulator where there is a pressure decrease of gas to the established value and its maintenance at the set level, and further via the output crane arrives to the consumer.
At increase in output pressure above an admissible preset value the valve including which is built in the regulator opens safety waste and there is a dumping of gas into the atmosphere. At further increase or decrease in controlled pressure of gas over admissible limits the safety and locking valve which is built in the regulator works, blocking a gas input in the regulator. On the entrance gas pipeline the manometer intended for measurement of entrance pressure and determination of pressure difference on the filtering cartridge is installed. The most admissible pressure drop on the filter cartridge — 10 kPa.
In case of repair of the equipment at the closed entrance and output cranes gas arrives to the consumer on the bypass gas pipeline — a baypas.
Control of pressure is made on the output manometer.
On the entrance gas pipeline after the entrance crane, after the regulator of pressure of gas and on a baypasa blowing-off pipelines are provided.
