Abstract

The invention provides an energy-saving automotive CNG pressure reducer which comprises a pressure reducer body. A high-pressure solenoid valve assembly is arranged at the bottom of the pressure reducer body, a high-pressure inlet seat assembly and a piston type pressure reducing mechanism assembly are arranged on the side segment of the pressure reducer body, the high-pressure inlet seat assembly communicates with the high-pressure solenoid valve assembly, and the high-pressure solenoid valve assembly communicates with the piston type pressure reducing mechanism assembly. A balance valve assembly and a second-level membrane type pressure reducing mechanism assembly are arranged in the pressure reducer body, the second-level membrane type pressure reducing mechanism assembly communicates with the piston type pressure reducing mechanism assembly, and the balance valve assembly is connected with the second-level membrane type pressure reducing mechanism assembly.

Description

technical field [0001] The invention relates to, in particular, an energy-saving CNG pressure reducer for vehicles. 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 an energy-saving CNG pressure reducer for vehicles to solve the above-mentioned problems well. [0004] In order to meet the above requirements, the technical solution adopted by the present invention is to provide an energy-saving CNG pressure reduce...
