Problems solved by technology

[0002] In terms of air transmission of the connector, the sealing method of the high-pressure air circuit is commonly used. The seal is arranged on the connection interface, and it is sealed after being squeezed and compressed by a mechanical structure. When the transmitted gas pressure exceeds a certain limit, the seal at the connection interface will Leakage of high-pressure gas will occur, so it is not suitable for high-pressure gas transmission

Embodiment Construction

[0019] Below in conjunction with above-mentioned accompanying drawing example the present invention is described in further detail:

[0020] The high-pressure gas circuit connector of the present invention includes a plug and a socket.

[0021] Among them, the plug includes a plug gas circuit jack 1, a gasket 2, a sealing gasket 3, an unlocking sleeve 4, a locking spring 5, a shell 6 and a nut 7, and the plug gas circuit jack 1 is a shaft part, which is provided with a high-pressure gas passage. Through hole, the tail is a threaded connection interface, which is used to connect the gas pipeline. In order to realize the high-pressure sealing of the mating interface, the sealing gasket 3 and the gasket 2 are arranged in the hole of the air passage socket 1. The sealing ring 3 is made of flexible silicon rubber material, and is designed as a stepped inner hole structure, with For a better sealing function, the gasket 2 is made of flexible polytetrafluoroethylene material, which ...

Abstract

The invention relates to a high-pressure gas circuit connector which consists of a plug and a socket, wherein the plug comprises a gas circuit jack, a housing and a nut. The gas circuit jack is provided with a through hole through which high-pressure gas passes; the socket comprises a gas circuit contact pin, a housing and a tail sleeve; the gas circuit contact pin is provided with a through holethrough which the high-pressure gas passes; the plug of the connector is provided with an unlocking sleeve and a locking spring simultaneously; a gland bush and a gasket are arranged in the gas circuit jack; the unlocking sleeve is arranged on the front end of the gas circuit jack; the locking spring is arranged in a cavity formed by the housing, the unlocking sleeve and the gas circuit jack; thesocket is provided with a release sleeve and a release spring simultaneously; the circumference of the side wall of the front end of the housing of the socket is provided with a plurality of holes, inwhich corresponding steel balls are arranged, and each hole mouth is provided with a position limiting structure; and the release sleeve and the release spring are arranged between the housing and the gas circuit contact pin. Due to the sealing performance and a rigidity connection structure, the invention has a self-locking function and can bear and transmit gas with quite high pressure.

Description

technical field [0001] The invention relates to a high-pressure gas circuit connector and belongs to the technical field of connectors. Background technique [0002] In terms of air transmission of the connector, the sealing method of the high-pressure air circuit is commonly used. The seal is arranged on the connection interface, and it is sealed after being squeezed and compressed by a mechanical structure. When the transmitted gas pressure exceeds a certain limit, the seal at the connection interface will Leakage of high-pressure gas will occur, and it is not suitable for high-pressure gas transmission. In addition, when the connector transmits high-pressure gas, a separation force will be generated at the two connection interfaces of the high-pressure gas circuit, which will separate the two connecting parts of the high-pressure gas circuit. Require. Aiming at the shortcomings of connectors in high-pressure gas transmission, the high-pressure gas connector of the prese...
