Description

A quick-release check valve

Technical Field

The utility model relates to the technical field of check valves, in particular to a quick-disassembly check valve.

Background Art

A check valve is a valve device that prevents fluid backflow, also known as a non-return valve. Its main function is to prevent the medium from flowing in the pipeline in the reverse direction to prevent equipment damage or operational failure. The check valve is usually installed in the reverse direction of the pipeline. The mechanical structure of the valve or spring and other devices can open the valve during forward flow and close the valve during reverse flow to prevent reverse flow.

Most of the existing check valves are of an integrated structure, which is troublesome to disassemble and difficult to repair. When damage occurs during operation, the maintenance cost is high.
