Abstract

The invention discloses a composite pressure reduction system, comprising a gas control switch with a pressure sensor, a plurality of serially connected drum type reducers, a transmission pipeline connected with the above two devices and a gas storage tank, characterized in that the gas control switch comprises a gas switch body equipped with a pressure sensor, the pressure sensor is arranged on the lower part of the gas switch and controls the open and close of the gas switch by a controller, when an engine stops working, the sensor closes the gas switch by the controller; the drum type reducer comprises a case of the reducer, a gas inlet, a gas outlet and a reduction chamber, the case is drum type, the two sides in the reducer are provided with two reduction diaphragms. The system performance is superior, and is safe to use.

Description

Technical field: [0001] The invention relates to a decompression system, in particular to a composite decompression system with a gas control switch and a drum pressure reducer. Background technique: [0002] The existing pressure reducer is a key part between the gas cylinder and the engine in a gas vehicle. It reduces the high-pressure natural gas in the cylinder to normal pressure and enters the mixer before entering the engine. At present, the more advanced one is the integrated three-stage pressure reducer, that is, the three-stage decompression chamber and the depressurized chamber are coaxially arranged, and there are set Valve seat, this pressure reducer realizes a relatively stable air supply to the mixer. However, this kind of pressure reducer is generally used in large-scale gas engines such as gas vehicles, and has a complex structure, high cost, and is easily damaged. [0003] In addition, the disadvantages of poor performance when the control switch is used i...
