This series of pressure regulating stations usually adopt skid-mounted structure, which is mainly suitable for distributing stations of long distance natural gas transmission pipeline, and is the key equipment for long distance natural gas transmission pipeline to enter the city pipe network. It is mainly used for pressure regulation and pressure stabilization of high and high pressure and high pressure gas pipe network of city gate station, distribution station, etc. It has the functions of purification measurement, pressure regulation distribution, safety protection, etc. It can also be equipped with gas alarm system, odour system and automatic control system according to user requirements. Automatic control system is based on the need to collect field pressure, temperature, differential pressure, flow, gas components, equipment operating state and other parameters, can achieve remote adjustment, remote measurement, remote control and other functions.
