Problems solved by technology

[0002] At present, the gas supply system installed with a pressure reducer cannot automatically release the downstream gas after the switch of the pressure reducer is turned off. If a closed cavity is formed downstream, the downstream equipment will always be under pressure, so it will be difficult for some valves and sensitive components. Will cause damage and shorten service life

Abstract

The invention discloses a pressure reducing linkage low-pressure release gas pressure reducer which comprises a gas inlet nozzle, a shell, a pressure regulating assembly and a pressure reducing assembly. When the screw rod is rotated to move in the direction close to the linkage valve assembly, the linkage valve assembly pushes the pressure reduction assembly to move through the ejector rod, and gas enters the cavity II from the cavity I; when the rotating screw moves in the direction away from the linkage valve assembly, the ejector rod moves upwards, the pressure adjusting spring is in a stretching state, the linkage valve assembly is separated from the ejector rod and opened, and gas enters the outer shell from the second cavity to be exhausted. Downstream gas can be released while the pressure reducer handle is closed, downstream equipment is protected from being pressed for a long time, and the product is compact in structure and high in reliability.

Description

technical field [0001] The invention relates to the technical field of pressure reducers, in particular to a decompression linkage low pressure release gas pressure reducer. Background technique [0002] At present, the gas supply system installed with a pressure reducer cannot automatically release the downstream gas after the switch of the pressure reducer is turned off. If a closed cavity is formed downstream, the downstream equipment will always be under pressure. In this way, some valves and sensitive components will be damaged It will cause damage and shorten the service life. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art and provide a decompression linkage low-pressure release gas pressure reducer. The present invention can open the pressure relief valve while closing the pressure relief valve by linking the pressure relief valve with the switch handle of the pressure relief valve. Press the v...
