Abstract

The utility model relates to a pipe joint. The pipe joint is characterized in that an aluminum-plastic composite pipe is arranged in a body. A sealing ring, a spacing ring, and a clamping ring are orderly sheathed on the aluminum-plastic composite pipe. A screw cap is arranged outside the body, and a thread which is corresponding to the screw cap is arranged on the body. Due to the fact that the structure is adopted by the pipe joint, when the aluminum-plastic composite pipe is connected with a bent head, a tee, and a straight way, tapping is not needed. The pipe joint is directly used, and connecting and sealing tasks can be conveniently finished by the pipe joint.

Description

Pipe joint

The utility model relates to a kind of pipe joint.

In people's daily production and life, various pipelines are necessary tool of transport of water, gas.Mostly pipeline in the past is metallic conduit, exists many shortcomings.Industry has emerged the upsurge that changes the conventional pipelines material both at home and abroad in recent years, present stage mature technique be to replace metallic conduit with aluminium-plastic composite pipe, aluminium-plastic composite pipe is compared with traditional metallic conduit and had the following advantages: nontoxic, corrosion-resistant, light weight, mechanical strength height, resistance to heat is good, brittle temperature is low, long service life, tube fluid resistance are low, less scaling, so aluminium-plastic composite pipe has good application prospects, but the pipe joint mode of conventional pipelines but is not suitable for aluminium-plastic composite pipe.

The purpose of this utility model provides a kind of pipe joint of aluminium-plastic composite pipe that is exclusively used in to remedy the deficiency of prior art.

The purpose of this utility model is achieved in that pipe joint, comprises body, it is characterized in that: aluminium-plastic composite pipe is arranged in body; On aluminium-plastic composite pipe, be with seal ring successively, cage ring and snap ring; External nut arranged at this, the screw thread that adapts with nut is arranged on the body.

Because the utility model adopted said structure, make aluminium-plastic composite pipe at connecting bend, threeway and when straight-through need not tapping, directly uses the utility model just can finish connection and sealing task.

Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:

Fig. 1 is the utility model embodiment's a structural representation:

Embodiment:

Pipe joint comprises body 1, and aluminium-plastic composite pipe 2 is arranged in body 1; On aluminium-plastic composite pipe 2, be with seal ring 3 successively, cage ring 4 and snap ring 5; Nut 6 is arranged outside body 1, the screw thread that adapts with nut 6 is arranged on the body 1.

First with nut 6, snap ring 5, cage ring 4 and seal ring 3 are inserted in successively from the cut ends of aluminium-plastic composite pipe 2.Then above-mentioned part is pushed in the body 1.The screw thread that matches with nut 6 is arranged on the main body 1.Rotary nut 6, in nut 6 rotation drive-in steps, the also stressed propelling of snap ring 5, and power passed to seal ring 3 by cage ring 4, and seal ring 3 is compressed, snap ring 5 is subjected to impacting force and tightens up simultaneously, the exocuticle of last snap ring 5 incision aluminium-plastic composite pipes 2 has just been finished connection and seal process.

Claims (1)

1, pipe joint comprises body, it is characterized in that: aluminium-plastic composite pipe is arranged in body; On aluminium-plastic composite pipe, be with seal ring successively, cage ring and snap ring; External nut arranged at this, the screw thread that adapts with nut is arranged on the body.
