Description

Hydraulic one-way valve

Technical Field

The utility model relates to a connecting device capable of being quickly disassembled and assembled, in particular to a hydraulic one-way valve.

Background

The quick joint comprises a hydraulic quick joint and various fluid quick joints, and is a connecting device for quickly connecting or disconnecting pipelines and realizing quick assembly and disassembly. The quick connector has a bidirectional non-return function, so that the pipeline is free from leakage when disconnected, and therefore, the quick connector is widely applied to the fields of petroleum, metallurgy, hydropower, engineering machinery, ships, electromechanical equipment and the like. The quick joint connecting structure is the most important part of the quick joint, and the connecting mode and the structure of the quick joint directly determine the use convenience, the reliability and the product quality of the quick joint. The quick connector is composed of a female connector and a male connector, and has a plurality of parts, so that the use cost is higher in some occasions.

Disclosure of Invention
