Abstract

The invention relates to a multifunctional hydraulic control valve, and relates to the technical field of valves. The multifunctional hydraulic control valve comprises a valve body, a valve cover and a diaphragm device, and is characterized by comprising an upper cavity base arranged between the valve body and the valve cover, wherein the lower part of the upper cavity base is provided with a through hole, and the through hole is provided with a blocking cover; an upper cavity chamber is formed between the valve cover and the valve body, and the interior of the valve body is provided with a lower cavity chamber; and the valve cover is connected with the upper cavity base through a fastening piece, and the upper cavity base is connected with the valve body through a fastening piece. The multifunctional hydraulic control valve provided by the invention has the advantages that the structural design is reasonable, the maintenance and part replacement are convenient, the multifunctional hydraulic control valve has multiple functions such as slow opening, slow closing and quick closing, and the multifunctional hydraulic control valve is practical and high-efficiency.

Description

Technical field: [0001] The invention relates to the technical field of valves, in particular to a multifunctional hydraulic control valve. Background technique: [0002] The hydraulic control valve is a valve controlled by water pressure. It consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. The hydraulic control valve separates the membrane type and the piston type. The working principle is the same. Both are driven by the pressure difference △P between the upstream and downstream, and are controlled by the pilot valve, so that the hydraulic differential operation of the diaphragm (piston) is completely automatically adjusted by hydraulic power, so that Make the main valve disc fully open or fully closed or in regulation. However, the existing hydraulic control valves and multifunctional hydraulic control valves are all provided with a single cavity, and their functions are relatively single. In addition, the oute...
