Abstract

The invention provides a single-diaphragm hydraulic control valve, and belongs to the field of valves. The single-diaphragm hydraulic control valve comprises a main valve, wherein the left and right ends of the main valve are respectively an inlet end and an outlet end; a valve cover detachably connected with the main valve is arranged at the side part of the main valve; a semispherical diaphragm is arranged between the valve cover and the main valve; the inner spherical surface of the diaphragm is towards the valve cover; the diaphragm is manufactured by an elastic material, and can generate elastic deformation; the main valve has a stop structure inside; the stop structure comprises an arched stop surface bonded with the outer spherical surface of the diaphragm; the connection between the inlet end and the outlet end can be stopped through a stop effect of the stop structure and the diaphragm; a water inlet cavity and a control cavity are communicated through a guide pipe; the guide pipe is connected with an adjusting pipe; and a pilot valve is arranged on the adjusting pipe. The hydraulic control valve and a traditional hydraulic control valve have qualitative differences in the working process, so that the service life of the whole hydraulic control valve is prolonged, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to the field of valves, in particular to a single-diaphragm hydraulic control valve. Background technique [0002] Valves are one of the most commonly used components in various mechanical and engineering fields. Valves are divided into various types according to their functions and structures. [0003] The hydraulic control valve is a valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be evolved into remote control float valve, pressure reducing valve, slow-closing noise reduction check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, electric control valve, limiter flow control valves, emergency shut-off valves, etc. Filters, etc. should be installed in front of the hydraulic contro...
