Abstract

The invention discloses a two-stage pressure reduction regulating valve. The two-stage pressure reduction regulating valve solves the technical problems that an existing single-stage pressure reduction valve cannot meet the higher pressure accuracy requirement and the requirement for stable output of quantitative pressure. According to the technical scheme, the two-stage pressure reduction regulating valve comprises a valve body, a first-stage pressure reduction piston, a second-stage pressure reduction piston and an exhaust piston. The first-stage pressure reduction piston is arranged in a valve chamber, the second pressure reduction piston is arranged in the valve chamber, and the exhaust piston is arranged in the valve chamber and located between the first-stage pressure reduction piston and the second-stage pressure reduction piston. The two-stage pressure reduction regulating valve has the advantages that two sets of pressure reduction mechanisms are adopted, and when the pressure of a gas source changes, gas passing a gas inflow mechanism enters the body and then is subjected to two-stage pressure reduction; the outlet flow can be guaranteed, the pressure does not change, and the accuracy of the output flow is kept stable and accurate.

Description

technical field [0001] The invention relates to a gas pressure regulating valve, in particular to a two-stage decompression regulating valve. Background technique [0002] In the fields of industry, medical treatment, scientific research, etc., it is usually necessary to use a gas decompression regulating valve to adjust the gas stored in the high-pressure cylinder into a stable low-pressure gas for use. [0003] Existing gas pressure reducing valves are all single-stage pressure reducing valves, which cannot meet the requirements of higher pressure accuracy and stable output quantitative pressure. Contents of the invention [0004] The technical problem to be solved by the present invention is that the single-stage pressure reducing valve in the prior art cannot meet the requirements of higher pressure accuracy and stable output quantitative pressure. [0005] The design concept of the present invention is to adopt two-stage decompression to meet the requirements of high...
