The working principle of the natural gas pressure regulating station and what is the natural gas pre

That is, the pressure of natural gas transported by the external trunk pipeline is very high, about dozens of kilograms, and the natural gas pressure used at home needs to be relatively low, about 3kpa, so an intermediate device is needed to adjust the natural gas pressure of the pipeline for civil use. These devices are placed in the house and are called pressure regulating stations.

It should be a gas pressure regulating station, which is a facility that automatically adjusts and stabilizes the pressure in the pipeline network in the city gas transmission and distribution system. The main valves of the incoming and outgoing gas pipelines are located at a certain distance outside the station.

Gas pressure regulating stations can be divided into high and medium pressure regulating stations, high and low pressure regulating stations, medium and low pressure regulating stations according to the pressure of inlet and outlet pipelines. Gas pressure regulating stations can be installed in the open air, on a separate structure above ground, in an underground room, in a room or in the basement of a building, or on a roof platform, for which different regulations differ.

Summary. When the gas consumption at the outlet increases or the inlet pressure P1 decreases, the gas outlet pressure P2 decreases, causing the pressure up and down the film to be unbalanced, and the film is pushed down by the spring force F at this time, and the valve stem is driven to open the valve at the same time, and the gas flow rate increases, so that the pressure is restored to the equilibrium state. On the contrary, when the gas consumption at the outlet decreases or the inlet pressure P1 increases, the gas outlet pressure P2 increases, and the film overcomes the spring force f at this time and rises, and the valve stem is pulled at the same time to make the valve close, the gas flow rate is reduced, and the outlet pressure is gradually restored to the original state.

When the gas consumption at the outlet increases or the inlet pressure P1 decreases, the gas outlet pressure P2 decreases, resulting in an imbalance in the upper and lower pressure of the film, and the film is pushed down by the spring force f at this time, and the valve stem is driven to open the valve at the same time, and the gas flow rate increases, so that the pressure of the high partner is restored to the equilibrium state. On the contrary, when the gas consumption at the outlet decreases or the inlet pressure P1 increases, the outlet pressure P2 increases, and the film overcomes the spring force f at this time, and at the same time pulls the valve stem to close the valve small, the gas flow rate decreases, and gradually returns the outlet pressure to the original state.

Hope it helps.

The main functions of the gas pressure regulating station are pressurization, pressure reduction, and pressure regulation.

The pressure regulating station has the function of raising and lowering the gas pressure of the pipeline to facilitate the transportation of gas. The main function of the gas pressure regulating station is to regulate and stabilize the system pressure, and to control the gas flow of the gas transmission system, and to protect the system from excessive or low outlet pressure.

The main functions of the gas pressure regulating station are: pressurization, pressure regulation and pressure reduction.

The main components of the natural gas pressure regulating station:

Inlet insulated joints (electrically insulated pipelines), emergency shut-off valves, flow meters, two-stage filter separators, pressure regulators, condensate storage tanks (for sewage collection), electrical instrument control systems.
