Description
Technical field
It the utility model is related to a kind of conduit coupling.
Background technology
At present, metallic conduit connection is all to be connected using pipeline tapping threaded connection or welding flange monkey with screw rod.This
Both of which is pretty troublesome：When tapping is not only taken a lot of work, also destroy the wall thickness of pipeline, easily embroidered again after long-term water inlet it is dead, unsuitable the
Secondary maintenance；When welding flange docking is also taken a lot of work very much, and docking is quite accurate.
Utility model content
Technical problem to be solved in the utility model is, there is provided a kind of conduit coupling, pipeline do not have to tapping, not yet
Must welding flange, it is simple to operate, it is convenient and swift.
In order to solve the above-mentioned technical problem, the utility model provides a kind of conduit coupling, and it includes body, the pipe
The middle part outer wall of body is provided with annular boss, and both ends are respectively equipped with the external screw thread being connected with nut；The nut is in cone-shaped, outside it
The middle part of the body gradually increases to the end direction of the body without leave；Pipe between the annular boss and the nut
Body is provided with tear connector, and the tear connector includes outer tube and inner tube, is provided between the outer tube and inner tube and is available for pipe
The interlayer that road tube wall engagement sleeves connect；The said inner tube relative with the external screw thread is provided with tear tube wall, the tear tube wall energy
Expanded in the presence of the nut and compress pipe wall.
As the preferable scheme of the utility model, the periphery of the nut is provided with seam guide piece, and the seam guide piece is broken with described
The tear of slit-tube wall coordinates.
As the preferable scheme of the utility model, the externally threaded hand of spiral at the body both ends is opposite.
As the preferable scheme of the utility model, the first water shutoff circle is provided between the interlayer and pipeline.
As the preferable scheme of the utility model, the tear connector is removably socketed in the annular boss and institute
State on the body between nut.
As the preferable scheme of the utility model, the second water shutoff is provided between the tear connector and the body
Circle.
Implement a kind of conduit coupling of the present utility model, compared with prior art, have the advantages that：
After the conduit coupling set connects both ends pipeline, with pipe wrench vise annular boss reverse conduit coupling, make its two
The nut at end is mobile to centre, and pushes tear tube wall using the conical surface of nut, tear tube wall is expanded and is compressed pipe wall,
Achieve a fixed connection.It can be seen that using the conduit coupling, pipeline does not have to tapping, also need not welding flange, it is simple to operate, side
Just it is quick.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, the accompanying drawing of embodiment will be made below simple
Ground introduction.
Fig. 1 is a kind of structural representation of conduit coupling provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, preferred embodiment of the present utility model, a kind of conduit coupling, it includes body 1, the body 1
Middle part outer wall be provided with annular boss 2, both ends are respectively equipped with the external screw thread 6 being connected with nut 3, and the external screw thread 6 at the both ends of body 1
Hand of spiral it is opposite；The nut 3 is in cone-shaped, end direction of the middle part of body 1 described without leave to the body 1 outside it
Gradually increase；Body 1 between the annular boss 2 and the nut 3 is provided with tear connector 4, the tear connector 4
The interlayer for being available for the tube wall of pipeline 5 to coordinate socket is provided with including outer tube 41 and inner tube 42, between the outer tube 41 and inner tube 42；With institute
State the relative said inner tube 42 of external screw thread 6 and be provided with tear tube wall 43, the tear tube wall 43 can be in the presence of the nut 3
Expand and compress the tube wall of pipeline 5.In use, pipeline 5 is socketed in the interlayer at pipeline connection both ends, after set connects pipeline 5,
The body 1 of the torsion conduit coupling of annular boss 2 is vised with pipe wrench, makes the nut 3 at its both ends mobile to centre, and utilize nut
3 conical surface pushes tear tube wall 43, tear tube wall 43 is expanded and is compressed the tube wall of pipeline 5, achieves a fixed connection.It can be seen that use
The conduit coupling, pipeline 5 do not have to tapping, also need not welding flange, it is simple to operate, it is convenient and swift.
In order to which nut 3 will not rotate when ensureing that body 1 reverses, the periphery of the nut 3 is provided with seam guide piece 7, described
The tear of seam guide piece 7 and the tear tube wall 43 coordinates.
In order to ensure the sealing of pipeline connection, the first water shutoff circle 8 is provided between the interlayer and pipeline 5.
More, the tear connector 4 is removably socketed in the pipe between the annular boss 2 and the nut 3
On body 1.Such design, can reduce the cost of manufacture of conduit coupling, and and can facilitates conduit coupling to repair and change.Enter
One step, in order to ensure the sealing of pipeline connection, the second water shutoff is provided between the tear connector 4 and the body 1
Circle 9.
Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and covered
Scope.
