Description

MPP is managed

Technical field

Pipe technical field is the utility model is related to, is especially a kind of MPP pipes.

Background technology

MPP pipes are also known as MPP power cable protecting pipes, are divided into digging type and no-dig technique type, MPP no-dig technique pipes are also referred to as MPP Push pipe or support trombone slide.MPP pipes use modified polypropene as main raw material(s).The characteristics of with high temperature resistance, proof to external pressure, it is applied to More than 10KV high voltage transmission line cable duct bank tubing.And current MPP pipes are in often the middle length for through hole after making Cylinder, shape can not change, some occasions using when generally require MPP pipes install elbow to overcome installation environment, make Used time is more troublesome.

The content of the invention

In view of the defects of above-mentioned prior art, the purpose of this utility model is：A kind of MPP pipes of convenient use are provided.

Technical solution of the present utility model is：MPP is managed, and it includes two MPP pipes main bodys and installed in two MPP Universal pipe between pipe main body, the Universal pipe include spring and are arranged on the joint at Universal pipe main body both ends, and two joints are equal It is integrally formed by cylindricality connecting portion and cone connection, and cylindricality connecting portion is fixed with spring end, on the outer wall of the spring Multiple diaphragm seals in a ring are coated with, are cased with a sealing ring respectively outside two joints, the end sleeve of the MPP pipes main body is in joint On, and sealing ring is stuck between MPP pipes main body and joint.

Further, the inwall of the MPP pipes main body is provided with froth bed.

Further, the spring is stainless steel spring, and the diaphragm seal is stainless steel substrates.

Further, a neck, the sealing ring card are respectively equipped with the cylindricality connecting portion and cone connection outer wall Enter in a wherein neck.

Further, the sealing ring is rubber ring.

Further, the angle of the cone connection outside wall surface and cylindricality connecting portion outside wall surface is α, and α angle is 2 To 5 degree.

Managed using MPP provided by the utility model, its advantage is：It includes two MPP pipes main bodys and installation Universal pipe between two MPP pipe main bodys, Universal pipe can arbitrarily be bent when in use, can be with by the flexural property of spring The shape and angle of Universal pipe are adjusted, can just be used after coordinating MPP pipe uses under different installation environments；And diaphragm seal Can will it is spring sealed live, then whole MPP allowed for by the setting of sealing ring manage that there is preferable sealing effectiveness, play anti- Water dustproof effect.

Brief description of the drawings

Fig. 1 is overall structure diagram of the present utility model；

Fig. 2 is decomposing schematic representation of the present utility model；

Fig. 3 is the enlarged diagram of a-quadrant in Fig. 2.

Shown in figure：1-MPP pipe main bodys, 2-Universal pipe, 21-spring, 22-joint, 221-cylindricality connecting portion, 222-cone connection, 3-diaphragm seal, 4-sealing ring, 5-froth bed, 6-neck.

Embodiment

For it is relatively directly perceived, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model accompanying drawing Nonrestrictive feature description is as follows：

As shown in Fig. 1-Fig. 3, MPP pipe, it include two MPP pipes main bodys 1 and installed in two MPP pipes main bodys 1 it Between Universal pipe 2, Universal pipe 2 includes spring 21 and is arranged on the joint 22 at the main body both ends of Universal pipe 2, and two joints 22 are by post Shape connecting portion 221 and cone connection 222 are integrally formed, and cylindricality connecting portion 221 is fixed with the end of spring 21, outside spring 21 Multiple diaphragm seals 3 in a ring are coated with wall, a sealing ring 4, the end sleeve of MPP pipes main body 1 are cased with respectively outside two joints 22 On joint 22, and sealing ring 4 is stuck between MPP pipes main body 1 and joint 22.

The inwall of MPP pipes main body 1 is provided with froth bed 5, has buffering effect, plays a part of anti-external impacts.

Spring 21 is stainless steel spring 21, and diaphragm seal 3 is stainless steel substrates, will not be got rusty, service life length.

A neck 6 is respectively equipped with cylindricality connecting portion 221 and the outer wall of cone connection 222, sealing ring 4 is caught in wherein one card In groove 6, the angle of the outside wall surface of cone connection 222 and the outside wall surface of cylindricality connecting portion 221 is α, and α angle is 2 to 5 degree, square Just cone connection 222 is caught in MPP pipes main body 1.When MPP pipes 1 internal diameter of main body is smaller, sealing ring 4 can be stuck in taper connection In neck 6 in portion 222, when MPP pipes 1 internal diameter of main body is larger, sealing ring 4 can be stuck in the neck 6 on cylindricality connecting portion 221 In, it is flexible and convenient to use.

Sealing ring 4 is rubber ring, and service life is grown.

MPP pipes provided by the utility model, it includes two MPP pipes main bodys 1 and installed in two MP P pipes main body 1 Between Universal pipe 2, Universal pipe 2 can arbitrarily be bent when in use, and Universal pipe 2 can be adjusted by the flexural property of spring 21 Shape and angle, coordinate MPP pipe uses after can just be used under different installation environments；And diaphragm seal 3 can be by spring 21 seal up, then allow for whole MPP pipes by the setting of sealing ring 4 and have preferable sealing effectiveness, play waterproof and prevent Dirt acts on.

Certainly, it these are only preferred embodiment of the present utility model, it is non-therefore limit to patent of the present utility model Scope, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, all should similarly wrap It is contained within scope of patent protection of the present utility model.
