Abstract

The invention discloses a fuel gas pressure regulation device for a city gas gate station. The fuel gas pressure regulation device for the city gas gate station comprises a filtering purification system 1, a metering system 2, a safety protection facility system 3, a pressure regulation system 4, a valve system 5, a heat exchange system 6, a leakage alarm controller and sound-light alarm system 7, a pressure transmitting system 8, a temperature transmitting system 9, and a data collection system 10. The fuel gas pressure regulation device (skid-mounted device) for the city gas gate station is the key equipment for a natural gas long-distance transport pipeline to enter a city pipe network and has the functions of purification, metering, pressure regulation, distribution, safety protection and the like, a fuel gas alarm system, an automatic control system and an odorizing device can be arranged according to requirements, and the pressure-regulation gas gate station is generally of a skid-mounted structural form. The fuel gas pressure regulation device for the city gas gate station can be widely used for transportation and distribution stations, city gas gate stations, regional pressure regulation and the like.

Description

technical field [0001] The invention relates to the field of gas pressure regulation, in particular to a gas pressure regulation device for a city gate station. Background technique [0002] Urban natural gas gate stations and storage and distribution stations are important infrastructures of urban natural gas transmission and distribution systems. Among them, the gate station is the gas source point of the urban transmission and distribution system, and it is also the gas distribution station where the long-distance natural gas pipeline enters the urban gas pipeline network. After odorization and distribution, it is sent to the urban transmission and distribution network or directly to large users. The main function of the natural gas high-pressure storage and distribution station is to store gas and deliver gas to the urban gas pipeline network after decompression. In order to ensure the normal operation of the storage and distribution station, the incoming gas from the ...
