Anti-leakage quick joint set

Abstract

The invention provides an anti-leakage quick joint set which comprises a male joint and a female joint, wherein the male joint and the female joint can bear high pressure and are simple in structure and convenient and quick to operate at the time of butt joint. The female joint comprises a female valve body and a core sleeve, wherein a choke plug is fixed at one end of a core shaft, the other end of the core shaft penetrates through the core sleeve, a slide sleeve is mounted on the core shaft in a sleeved mode, an elastic element is arranged between the slide sleeve and the female valve body or between the slide sleeve and the core sleeve, and the elastic element enables the slide sleeve to be in sealing contact with the choke plug and enables the core shaft to be in sealing contact with the core sleeve. The male joint comprises a male valve body and a valve core, wherein an elastic piece is arranged between the male valve body and the valve core, and the elastic piece enables the valve core to be in sealing contact with a valve seat. When one end of the male valve body is inserted into the female valve body, the male valve body pushes the slide sleeve to move for a distance A, the valve core pushes the core shaft to move for a distance B, B is shorter than A, and therefore sealing contact no longer exists between the valve core and the valve seat or between the choke plug and the slide sleeve or between the core shaft and the core sleeve. The slide sleeve comprises a polyurethane sleeve body and a choke sleeve body.

Description

technical field [0001] The technology relates to a joint, in particular to a high-pressure quick oil pipe joint. Background technique [0002] Leak-proof quick connectors are generally used for hose connections, which generally include male and female connectors. When in use, just connect the male connector with the female connector. However, generally after the male connector and the female connector are docked, fluid can be introduced into the pipeline (usually a hose). Before the male joint and the female joint are butted, because the male joint or the female joint cannot bear pressure, the pipeline cannot pass fluid. In addition, in the existing anti-leakage quick connectors, the internal structure of the male connector and the female connector is relatively complicated. When the male connector and the female connector are docked, the operation of connecting the internal channels of the male connector and the female connector is cumbersome and the connection speed is s...

AI Technical Summary

Problems solved by technology

In addition, in the existing anti-leakage quick connector, the internal structure of the male connector and the female connector is relatively complicated. When the male connector and the female connector are docked, the operation of connecting the inner channel of the male connector and the female connector is cumbersome and the connection speed is slow.

Third, the existing anti-leakage quick connectors have poor sealing effect and may easily cause fluid leakage
