Description

A kind of pipe joint

Technical field

The utility model relates to a kind of adapter assembly, especially a kind of be used between the connecting tube or pipeline and valve between pipe joint, belong to the assembling pipe joint technical field.

Background technique

All need use pipe joint between a lot of pipelines or between pipeline and the valve, the most frequently used pipe joint is respectively fixed to two pipes on two flange plate exactly, through bolt etc. flange plate is fixedly connected again.Generally speaking, in order to guarantee the sealing effect in the pipeline, pipe all adopts welding manner with being connected of flange plate, if damage of components is arranged like this, when need changing valve or flange plate etc., just need sever being connected of flange plate and pipe earlier, and ten minutes bothers.And link together through a lot of fixed blocks such as bolts often between two flange plate, this is for installation and removal of pipeline and valve inconvenience very all.For this reason, can not adopt welding or screw Placement, fixing connecting tube or pipeline and valve has become the problem that the people in the industry need solve.

On this problem; The people in the industry has made a lot of effort; For example Chinese patent number is the rapid pipe joint of ZL 200920197347.4, discloses a kind ofly to cooperatively interact through protecting jacket, movable sheath, protective pad and clip, tightens the rapid pipe joint that connects tube and tube or pipe and valve.Though this pipe joint can not adopt welding or screw Placement, be fixedly connected pipe or pipe and valve,, the component of its composition are more, and internal structure is more complicated also, and difficulty of processing is big, and cost is high; And after pulling down, inner component are easy to lose, and, after each dismounting, need the component of pulling down be adorned with sack or other, in order to avoid lose for this reason; If lost one or several component accidentally, the component that also need processing again to match, processing and use be the ten minutes trouble all.

The model utility content

The utility model purpose is that a kind of simple in structure, easy processing, pipe joint easy to use are provided for the deficiency that overcomes existing technology.

For achieving the above object, the technological scheme that the utility model adopts is: a kind of pipe joint comprises body, guide sleeve, seal ring, magnet and fixed cover; Said body is a tubulose, and its inboard middle part is provided with the annular lug that exceeds; Said guide sleeve is two, inserts in the body from the two ends of body respectively; One side of said guide sleeve is extended with guide ring; Said guide ring inserts in the annular lug, and the joint of guide sleeve and guide ring props up annular lug; Said seal ring is two, the two ends of inserting body respectively; Said seal ring is rubber ring, and an end face of seal ring props up the opposite side of guide ring on the guide sleeve; The external diameter of said seal ring is identical with the internal diameter at body two ends, and the other end of seal ring is concordant with the end face of body; Said magnet is circular, be fixed on the pipe to be connected, and magnet is wrapped in the seal ring; Said fixed cover is two, is fixed on the two ends of body respectively through being threaded; Have fixed hole in the said fixed cover in the heart; The diameter of the internal diameter of said guide sleeve, the internal diameter of magnet and fixed hole, all the external diameter with pipe to be connected is identical.

Preferably, have a notch on the said seal ring; The cross section of said seal ring is a U-shaped.

Preferably, said magnet is spliced by two semicircular ring.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

The pipe joint of the utility model scheme, it is simple in structure, easy processing; Has no the fixing Placement; Can pipe to be connected be fixed in the body through intrinsic guide sleeve, magnet and seal ring, fixed cover be tightened through being threaded be fixed on the body again, can realize between the pipeline or pipeline and valve between be fixedly connected; And it is simple to operate, easy to use, good sealing effect.
