Abstract

The invention discloses a pressure regulating valve comprising a valve body, a valve flap, a valve cover, a spring, a needle valve, an adjusting screw, a pilot valve, a regulating valve, a partitioning film, a valve rod and a valve seat. The upper portion of the valve body is provided with the valve cover, the partitioning film is arranged between the valve body and the valve cover, the pilot valve connects a valve cavity and a drainage cavity through a communication tube, a pressure gauge is arranged on the communication tube through the pilot valve and the drainage cavity, the regulating valve is connected to the position between the pressure gauge and the pilot valve for facilitating control, the needle valve connects the valve cavity and an incoming cavity of the valve body through a communication tube, and the pressure gauge is arranged on the communication tube between the needle valve and the incoming cavity. The pressure regulating valve has the advantages that structure is simple, installation and adjustment are facilitated, the tightness performance is fine, operation stability and reliability are high, and the pressure regulating valve has fine pressure regulating effect and low cost when being applied to a water supply system, a firefighting system and other industrial water supply systems.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a pressure reducing and stabilizing valve. Background technique [0002] The pressure reducing and stabilizing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment and keeps it stable. It is mainly used in water supply systems, fire protection systems and other industrial water supply systems. Because the existing pressure reducing and stabilizing valve mainly relies on the pressure of the spring to decompress and stabilize the pressure, it has defects such as large resistance, heavy weight, and unstable outlet pressure. Contents of the invention [0003] The object of the present invention is to provide a pressure reducing and stabilizing valve with large regulating flow rate, simple structure, stable and reliable operation and low cost. [0004] The technical solution adopted by the present invention to solve its technical ...
