Abstract
The utility model discloses a kind of MPP socket joint protection pipe, including tube body, the both ends of the tube body are respectively equipped with bellmouth and socket, and the tube body is equipped with annular groove close to the end face of bellmouth, is equipped with collocation structure in the annular groove.The protection pipe construction and installation are convenient, after long-term use, are arranged by the compensation to sealing structure, so that the socket joint junction of tubing still has good sealing performance, thus the inside cable in effective protection pipe.
Description
Technical field
The utility model relates to a kind of tubing, in particular to a kind of MPP socket joint protection pipes.
Background technique
With the development of China's power industry, the usage amount of power pipe is also quicklyd increase.In order to guarantee construction efficiency and at
This problem, the connection cooperation between a large amount of power pipe are carried out using Push-fit.But after the time using a bit, socket joint
There is connection and loosens, cause in rainwater dipping tube body, inside cable in the problems such as junction is due to sealing strip aging, external corrosion
Use seriously threatened, therefore, the safety in utilization of traditional socket joint connecting tube is not ideal enough, and service life is answered in many
Field can not also meet the requirements.
Utility model content
The purpose of this utility model is to provide for a kind of MPP socket joint protection pipe, and the protection pipe construction and installation are convenient, in length
After phase use, it is arranged by the compensation to sealing structure, so that the socket joint junction of tubing still has good sealing performance,
To the inside cable in effective protection pipe.
In order to achieve the above object, the utility model provides following technical solution: a kind of MPP socket joint protection pipe, including
Tube body, the both ends of the tube body are respectively equipped with bellmouth and socket, and the tube body is equipped with annular groove close to the end face of bellmouth, described
Collocation structure is equipped in annular groove, the inner wall of the bellmouth is equipped with limited block, and the end face of the socket is equipped with and annular groove
The groove to match, the groove is interior to be equipped with sealing ring, and the side of the socket is circumferentially spacedly distributed equipped with several along socket
Guiding groove, the guiding groove connects the stop collar extended along socket circumferential lengths, and the stop collar, which is equipped with, matches guiding groove
And the limited mouth being spaced apart.
It is further preferred that the collocation structure includes the water swelling sealing joint strip to offset with sealing ring, is set to suction
Reset spring between water Expansion sealing adhesive tape and annular groove.
It is further preferred that the quantity of the guiding groove and limited mouth is 4.
It is further preferred that the cross sectional shape of the limited block is identical as limited mouth.
The utility model has the beneficial effects that the protection pipe construction and installation are convenient, after long-term use, by sealing structure
Compensation setting so that the socket joint junction of tubing still there is good sealing performance, thus the inside in effective protection pipe
Cable.

Specific embodiment
We are described further a kind of MPP socket joint protection pipe described in the utility model in conjunction with attached drawing below.
As shown in Figures 1 and 2, a kind of MPP socket joint protection pipe of the present embodiment, including tube body 1, the two of the tube body 1
End is respectively equipped with bellmouth 2 and socket 3, and the tube body 1 is equipped with annular groove 4 close to the end face of bellmouth, sets in the annular groove 4
There is a collocation structure 5, the inner wall of the bellmouth 2 is equipped with limited block 21, and the end face of the socket 3 is equipped with to match with annular groove
Groove, the groove is interior to be equipped with sealing ring 31, and the side of the socket 3 is equipped with several guidance being circumferentially spacedly distributed along socket
Slot 32, the guiding groove 32 connect the stop collar 33 extended along socket circumferential lengths, and the stop collar 33 is equipped with matching guidance
Slot and the limited mouth 34 being spaced apart.The collocation structure 5 includes the water swelling sealing joint strip 51 to offset with sealing ring, setting
Reset spring 52 between water swelling sealing joint strip and annular groove.The quantity of the guiding groove 32 and limited mouth 34 is 4
It is a.The cross sectional shape of the limited block 21 is identical as limited mouth 34.The service condition of the protection pipe is substantially as follows: in connection,
The guiding groove of socket is aligned after limited block, socket is pushed into bellmouth, then rotates pine after socket makes limited block reach limited mouth
Operation is opened, connection can be completed.After tubing long-time service, sealing ring aging due to various reasons, so that it occurs centainly
Deformation, sealing effect decline push water swelling sealing joint strip by spring, avoid the occurrence of gap, ensure that sealing effect；Together
When water swelling sealing joint strip itself have the effect of in terms of sealing compensation it is good.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
