Quick butt joint connector

Abstract

The invention discloses a quick butt joint connector which is simple in structure and convenient and quick in butt joint operation. The quick butt joint connector comprises a female connector and a male connector which are connected, wherein the male connector or the female connector can bear high pressure before the male connector and the female connector are in butt joint. The female connector comprises a female valve body with a fluid channel, a core sleeve is positioned in the fluid channel, 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 sleeved on the core shaft, an elastic element is arranged between the slide sleeve and the female vale body or the core sleeve, and the elastic element enables the slide sleeve and the choke plug to be in sealing contact and the core shaft and the core sleeve to be in sealing contact. The male connector a male valve body with a runner, a valve core is positioned in the runner, an elastic part is positioned between the male valve part and the valve core, and the elastic part enables the valve core and the valve seat to be in sealing contact. When one end of the male valve body is inserted into the female valve body, the male valve body can push the slide sleeve to move the distance A, the valve core can push the core shaft to move the distance B, and the B is smaller than the A. Thus, the valve core and the valve seat are not in sealing contact, the choke plug and the slide sleeve are not in sealing contact, the core shaft and the core sleeve are not in sealing contact, and the fluid channel and the runner can form a through channel. Sealing rings are arranged on the core shaft and the valve core, and a location mechanism capable of limiting the male valve body to move is positioned on the female valve body.

Description

technical field [0001] The technology relates to a joint, in particular to a high-pressure quick oil pipe joint. Background technique [0002] Quick butt joints are generally used for hose connections and 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, the internal structure of the male joint and the female joint is relatively complicated in the existing quick butt joint. When the male joint and the female joint are butted, the operation of connecting the internal channels of the male joint and the female joint is cumbersome and the connection speed is slow. Thirdly, the sealing effect of the existing q...

AI Technical Summary

Problems solved by technology

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

Third, the sealing effect of the existing quick-joint joint is not good, and it is easy to cause fluid leakage
