Split butt joint and male joint and female joint thereof

Abstract

The invention discloses a split butt joint and a male joint and a female joint thereof. The male joint comprises a male valve body, a piston and a male valve core body, wherein a first fluid channel is formed in the male valve body in the axial direction; the piston is arranged in the first fluid channel of the male valve body in a sliding manner; the male valve core body sleeves the piston; and a first groove used for accommodating a first sealing element and a matched male valve core is formed in the position, in contact with the piston, of the male valve core body. The male joint is convenient to process, high in finished product rate, convenient to assemble, good in sealing performance, long in service life, high in practicability and wide in application range and has good market prospects.

Description

technical field [0001] The invention relates to the technical field of butt joints, in particular to a split type butt joint and its male and female joints. Background technique [0002] Butt joints are widely used in pipelines, with quick buckle and quick disassembly performances, and have an inseparable relationship with some industries related to gas or liquid. There are two types of quick connectors on the market. The first type is characterized by simple structure, convenient operation, automatic buckle and spring release, but the airtight effect is not ideal, especially when the pressure is higher, the sealing effect is worse. And the action is not accurate; the second type is characterized by complex structure, slow assembly, but good air tightness, accurate action, and automatic fastening and springing. [0003] At present, the spools of the above-mentioned second type of butt joints generally adopt integral spools, that is, grooves for placing sealing rings are arr...

AI Technical Summary

Problems solved by technology

However, due to the small size of the spool (that is, the male spool and the female spool), the size of the sealing ring must also be small. The difficulty is even more difficult, not only the processing of the groove is difficult; because there are processing errors in the processing of the groove, the adaptability between the groove and the sealing ring is poor, resulting in the failure of the sealing ring to be installed, which leads to the inability to assemble the entire butt joint. Waste of installation time and processing raw materials, increase the production cost and assembly cost of the butt joint, resulting in low processing efficiency; or the sealing ring can move in the groove, which leads to the movement of the sealing ring in the groove during installation or use, Long-term use will intensify the phenomenon of movement, which will lead to a decrease in the sealing performance of the butt joint, causing the fluid (ie gas or liquid) in the joint to leak, seriously affecting the service life and work efficiency of the butt joint
