Description

Technical Field

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] Most of the valves in high-pressure environments on the market have the following problems when used:

[0004] When traditional valves for high-pressure environments are actually used, the valves themselves have a single sealing function. When water flows through the valve port, the sealing structure itself will be damaged due to excessive pressure, and water will leak, resulting in poor sealing. When traditional valves for high-pressure environments are actually used, they are usually installed with fasteners. After long-term use, the surface of the fasteners will rust, making it difficult to remove the fasteners, increasing the difficulty of disassembly. Utility Model Content
