Abstract

The invention provides a natural gas vehicle CNG decompressor. The natural gas vehicle CNG decompressor comprises a decompressor body; a high pressure electromagnetic valve assembly is arranged at the bottom of the decompressor body; a high pressure inlet seat assembly and a piston type decompression mechanism assembly are disposed on the side section of the decompressor body; the high pressure inlet seat assembly communicates with the high pressure electromagnetic valve assembly; the high pressure electromagnetic valve assembly communicates with the piston type decompression mechanism assembly; a balance valve assembly and a two-stage diaphragm type decompression mechanism assembly are arranged inside the decompressor body; the two-stage diaphragm type decompression mechanism assembly communicates with the piston type decompression mechanism assembly; and the balance valve assembly is connected with the two-stage diaphragm type decompression mechanism assembly.

Description

technical field [0001] The invention relates specifically to a CNG pressure reducer for a natural gas vehicle. Background technique [0002] A pressure reducer is a component used in a car to depressurize natural gas. Existing pressure reducers generally adopt a diaphragm spring structure and a primary or secondary decompression method. This type of pressure reducer is used in CNG vehicles. With the application of LNG in automobiles, pressure reducers with a diaphragm spring structure gradually show problems such as being easy to be adjusted but difficult to stabilize and control during use, large in size, and inconvenient to install. Contents of the invention [0003] The object of the present invention is to provide a CNG pressure reducer for natural gas vehicles, which can well solve the above problems. [0004] In order to meet the above requirements, the technical solution adopted by the present invention is to provide a CNG pressure reducer for natural gas vehicle...
