Abstract

The invention provides an automotive CNG pressure reducer with a novel piston type pressure reducing mechanism. The automotive CNG pressure reducer with the novel piston type pressure reducing mechanism comprises a pressure reducer main body; the bottom of the pressure reducer main body is provided with a high-pressure magnetic valve assembly, the side section of the pressure reducer main body is provided with a high-pressure inlet seat assembly and a piston type pressure reducing mechanism assembly, the high-pressure inlet seat assembly is communicated with the high-pressure magnetic valve assembly, and the high-pressure magnetic valve assembly is communicated with the piston type pressure reducing mechanism assembly; a balance valve assembly and a two-level diaphragm-type pressure reducing mechanism assembly are arranged in the pressure reducer main body, the two-level diaphragm-type pressure reducing mechanism assembly is communicated with the piston type pressure reducing mechanism assembly, and the balance valve assembly is connected with the two-level diaphragm-type pressure reducing mechanism assembly.

Description

technical field [0001] The invention relates to the technical field of fluid pressure reducing valves, in particular to a vehicle CNG pressure reducing device with a novel piston type pressure reducing mechanism. Background technique [0002] Existing pressure reducers are mainly divided into diaphragm type and plunger type. Diaphragm type pressure reducer is mainly suitable for low pressure and small flow conditions, and plunger type pressure reducer is suitable for high pressure and large flow conditions; Existing automotive CNG pressure reducers are mainly diaphragm type and plunger type pressure reducer, but diaphragm type pressure reducer cannot achieve high pressure and large flow output, so it is often used in passenger cars, and it is difficult to be used in commercial vehicles system; although the plunger-type pressure reducer has a large flow rate and can be used in high-pressure systems, it also has the disadvantages of low pressure regulation accuracy, high-pres...
