Description

A kind of joint

Technical field

The utility model relates to a kind of connection set, relates in particular to a kind of joint.

Background technique

The joint of existing pipe-line system or high-pressure atomization system is to adopt FERRULETYPE to connect, working principle is that pipe is inserted in the cutting ferrule, utilize cutting ferrule nut check, the conflict cutting ferrule, cut pipe and obtain effective sealing, this ferrule fitting is installed inconvenient, and use is that nut screws the cutting ferrule front end outside and the applying of the fittings body conical surface, the inner edge pipe of nipping forms effective sealing, when installing in pipe-line system, nut screws dynamics and is difficult to grasp, thereby cause nut to burst apart, and it is inadequate to screw dynamics, pipe is leaked come off with pipe, and change trouble when changing, cost is high.

Summary of the invention

The utility model is for deficiency of the prior art, the joint that provide a kind of Simple fast is installed, saves the space, fixed performance is good.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals.

A kind of joint comprises an adapter body, and adapter body links to each other with the pipe of pipe-line system or high-pressure atomization system, and the adapter body place that interconnects end in pipe and adapter body is provided with draw-in groove, is provided with seal washer in the draw-in groove; Pipe overcoat snap ring is provided with coil tension spring between snap ring and the adapter body.

With the snap ring automatic tightening, keep tension in the absence of air pressure and hydraulic pressure during use, coil tension spring has solved the low problem that causes the generation of pipe retraction to leak and leak gas of pressure in the pipeline when release.Seal washer is arranged in the draw-in groove of adapter body, reduces the friction of seal washer and adapter body, and can not slide up and down.

As preferably, snap ring comprises clamping ring and the collar, and clamping ring is provided with a plurality of, is provided with clamping slot between every two adjacent clamping rings, and clamping ring is connected on the collar.Clamping slot so that snap ring can put by the automatic folding shrinkage porosite.

As preferably, the inboard of clamping ring is provided with the snap ring step.Snap ring is retracted to certain size, and the snap ring step can tightly block pipe, and can strengthen elastic recovery capability.

As preferably, seal washer is provided with two.Two seal washer folded double are better in the impacting with high pressure seal performance.

As preferably, coil tension spring is positioned at the attachment portion of clamping ring and the collar, and clamping ring is located at adapter body inside, and the collar and coil tension spring are located at the adapter body outside.

As preferably, the adapter body mobility is strong, can 360 ° regulates arbitrarily rotation.

According to the technical solution of the utility model, it is several times even tens times of ordinary couplings that the bearing of this joint pressed, and has high pressure resistantly, quick mounting, need not welding, simple dexterous, joint space-efficient effect, saves cost in as installed.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

A kind of joint comprises adapter body 1, seal washer 2, coil tension spring 3, snap ring 4.

Adapter body 1 is provided with two seal washers 2, a coil tension spring 3 and a snap ring 4.

Pipeline is provided with pipe 5, and adapter body 1 integral body and links to each other with pipe 5 in a tubular form.

Be provided with snap ring 4 in the adapter body 1, cover has coil tension spring 3 on the snap ring 4; In interconnecting the draw-in groove 11 of adapter body 1 of end, pipe 5 and adapter body 1 be provided with seal washer 2.

Snap ring 4 is the cylindric of hollow, and snap ring 4 comprises clamping ring 41 and the collar 42, and the collar 42 and coil tension spring 3 are positioned at adapter body 1 outside, and clamping ring 41 is positioned at adapter body 1 inboard.The collar 42 is circular, is enclosed within outside the pipe, and the clamping ring 41 that links to each other with the collar 42 is provided with polylith, and is separated from one another, such as the 6-8 piece, is provided with clamping slot 43 between two adjacent clamping rings 41, and corresponding quantity is 6-8, plays clamping action.Clamping ring 41 inboards are provided with snap ring step 44.

Coil tension spring 3 is contained between adapter body 1 and the snap ring 4, plays the automatic tightening effect.

The adapter body 1 of first seal washer 2 being packed into, again coil tension spring 3 is inserted in snap ring 4, the snap ring 4 press-in connector main bodys 1 of the coil tension spring 3 of packing into, after pipe 5 inserts, clamping ring 41 1 end automatic tightenings by the snap ring 4 in the adapter body 1, join voluntarily pipe 5 fixing, and by coil tension spring 3 that snap ring 4 is again fixing, two seal washers 2 that are provided with in the adapter body 1 obtain sealing with snap ring 4 planes on Double Pressures under the impact of pressure is sliding voluntarily, only need when unloading pipe snap ring 4 is depressed, can conveniently extract pipe 5.

Adapter body 1 is symmetrical set.

In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
