Anti-shake noise reduction pressure reducing valve

Abstract

The utility model relates to the technical field of pressure reducing valves, and discloses an anti-shake noise reduction pressure reducing valve which comprises a main valve body, a main valve cover and a valve element assembly. An inlet and an outlet are formed in the two ends of the main valve body, a valve body partition cavity part is arranged in the middle of the main valve body in the length direction, a cover installation opening is formed in the position, corresponding to the valve body partition cavity part, of the outer wall of the valve body, the main valve cover is installed on the cover installation opening, and an anti-shake assembly is installed on the valve body partition cavity part; the valve element assembly comprises a valve rod, a first clamping plate, a second clamping plate and a valve plate correspondingly matched with the anti-shake assembly are arranged in the length direction of the valve rod, a diaphragm is clamped between the first clamping plate and the second clamping plate, the periphery of the diaphragm is located between the main valve deck and the deck installation opening in the thickness direction, and the anti-shake assembly is connected to the surface of the valve rod. According to the anti-shake noise reduction pressure reducing valve, the anti-shake assembly is arranged, the guide frame is installed on the partition cavity part of the valve body, the valve rod is guided and limited, the stability of the valve rod in the movement process is improved, and the valve rod is prevented from shaking.
