Pressure regulating and metering platform for fuel gas

A pressure regulating and metering platform for fuel gas comprises a platform base with a house, an air inlet system, a first-level pressure reduction system, a heat exchange system and a second-level pressure reduction system, wherein the air inlet system, the first-level pressure reduction system, the heat exchange system and the second-level pressure reduction system are installed on the platform base, controlled by a control system and sequentially connected through a pipeline. The air inlet system comprises an air inlet pipeline, a high-pressure stop valve and a pneumatic emergency cut-off valve, wherein the high-pressure stop valve and the pneumatic emergency cut-off valve are connected to the air inlet pipeline. The air inlet pipeline is provided with a branch and connected with a pressure transmitter through the stop valve. The first-level pressure reduction system comprises a pipeline, a high pressure filter and a first-level pressure regulator, wherein the high pressure filter and the first-level pr
