Embodiment
The present invention is described in further detail below in conjunction with above-mentioned accompanying drawing example:
High-pressure gas circuit connector of the present invention comprises plug and socket.
Wherein, plug comprises plug gas circuit jack 1, packing ring 2, sealing gasket 3, separates lock tube 4, locking spring 5, shell 6 and nut 7, and plug gas circuit jack 1 is an axial workpiece, is provided with the through hole by pressurized gas, afterbody is the interface that is threaded, and is used to connect the gas circuit pipeline.For realizing plugging together the high pressure sealing at interface, described sealing gasket 3 of configuration and packing ring 2 in the hole of gas circuit jack 1, seal ring 3 adopts pliable and tough silicone rubber material manufacturing, and be designed to the inner hole structure of step type, has better sealing function, 2 employings of packing ring have flexible polytetrafluoroethylmaterial material manufacturing, have limit function, prevent that seal ring 3 accidents from deviating from.In order to realize the locking that plugs together of plug and socket, on the front end periphery of gas circuit jack 1, designed arc groove 1a.Assemble successively on the periphery of gas circuit jack and separate lock tube 4, locking spring 5 and shell 6, with nut 7 shell 6 is fixed on the gas circuit jack at last, 6 pairs of locking springs of shell 5 form and support, after lock tube 4 compression locking springs 5 are separated in promotion, separate lock tube 4 and can realize the locking and the release of plug and socket along the endwisely slipping of gas circuit jack 1.
As shown in Figure 2, the socket of connector of the present invention comprises shell 8, steel ball 9, separation sleeve 10, release spring 11, socket gas circuit contact pin 12 and tail cover 13, wherein, the front end of shell 8 is provided with a plurality of holes of circle distribution, configuration steel ball 9 in the hole, and the structure in hole is as shown in Figure 3, aperture in periphery orifice part position is less, promptly be provided with limit structure 8a, steel ball 9 is provided constraints, prevent that steel ball 9 from deviating from from the periphery of shell 8.In order all the time steel ball 9 to be limited in the hole of shell 8, except that the periphery aperture of shell 8 is less, separation sleeve 10 and release spring 11 have been installed in the hole of shell 8, release spring 11 has the initial compression amount, for separation sleeve 10 provides certain spring force, behind the compression release spring 11, separation sleeve 10 can endwisely slipping along shell 8.Because the restriction of shell 8 and separation sleeve 10, steel ball 9 can only radially slide in the hole of shell 8, realizes the function requirement of locking and release.Gas circuit contact pin 12 is an axial workpiece, and design has the through hole by pressurized gas, and afterbody is the interface that is threaded, and is used to connect the gas circuit pipeline.Tail cover 13 is used for gas circuit contact pin 12 is fixed on shell 8, forms stable socket.
Fig. 4 is the figure that plugs together of high-pressure gas circuit connector plug of the present invention and socket, as shown in the figure, and when plug and socket plug together, gas circuit jack 1 promotes separation sleeve 10 and moves backward, and compression release spring 11, steel ball 9 moves after withstanding and separating lock tube 4 simultaneously, and compression locking spring 5.Put in place when plugging together, promptly the arc groove of gas circuit jack 1 moves to steel ball 9 places, and this moment, steel ball 9 lost the support of gas circuit jack 1, under the spring force effect of locking spring 5, by separating lock tube 4 steel ball 9 is pressed in the arc groove of gas circuit jack, and limits moving radially of steel ball 9, realize locking.Simultaneously, release spring 11 is compressed, and has laid in and has separated required power.
Fig. 5 is the bitmap that plugs together of high-pressure gas circuit connector plug of the present invention and socket, and as shown in the figure, the steel ball 9 of socket snaps in the arc groove of gas circuit jack, finishes locking and indicates to plug together and put in place.In addition, after plug and socket plug together and put in place, because seal ring 3 is the inner hole structure of step type, the pressure that air pressure forms at the macropore place is bigger, to form one to plugging together the pressure that the interface promotes, thereby promote seal ring 3 and packing ring 2 to plugging together Interface Moving, but gas circuit jack 1 and gas circuit contact pin 12 are owing to be in the state of being locked, can not relatively move, just be pressed on after seal ring 3 and packing ring 2 move and plug together at the interface, realize self-tightening sealing, high sealing performance is then good more more for operating air pressure at this moment, satisfies good high pressure sealing requirement.
When plug separates with the socket release, after separating lock tube 4, pulling moves, and compression locking spring 5, separate move away steel ball 9 after lock tube 4 continues after, steel ball 9 no longer is limited, and under the spring force radial component effect of release spring 11, promotes steel ball 9 and moves radially, break away from the arc groove of gas circuit jack 1, the restriction that loses gas circuit jack 1 is release.Release spring 11 promotion plugs are forced to separate fast with socket after the release.
