Description

A kind of communication polyethylene pipe

Technical field

The utility model is related to a kind of tubing, in particular to a kind of communication polyethylene pipes.

Background technology

At present, PE tubing insulate since its is excellent, the performances such as ageing-resistant, corrosion-resistant, shock resistance are widely used in respectively A field, and gradually instead of steel pipe and cast iron pipe.In communication tubing field, the use of polyethylene pipe is more universal, still Due to single in structure so that tubing is easily damaged in practical applications, and in the construction area of part bending, it is impossible to very well Carry out install, influence construction speed, improve cost.

Utility model content

The purpose of this utility model has been to provide for a kind of communication polyethylene pipe, which has good resistance to old Change, fire resistance, service life is long, and can repeatedly be bent, and can effectively improve the installation effectiveness of tubing, adapts to each The complicated construction environment of kind, reduces cost input.

In order to achieve the above object, the utility model provides following technical solution：A kind of communication polyethylene pipe, including Tube body, the tube body include inner and outer tubes, said inner tube be PE hoses, the outer tube be PE hard tubes, the outer wall of said inner tube Guiding tendon equipped with shape of threads, the outer tube are detachably connected by guiding tendon and inner tube, and the outer wall of the outer tube is equipped with fire prevention Material layer and antiaging coatings, the inner wall of said inner tube are equipped with wire sheathing, and the inside of the wire sheathing is equipped with elasticity Filled layer, the elastic packed layer is interior to be equipped with several penetration pipes, and the inner wall of the penetration pipe, which is equipped with, increases sliding coating, the outer tube Including a number of long pipeline section and short sections.

It is further preferred that the elastic packed layer includes any one in silica gel, fire-resistant rubber, fire proofing firbre cloth.

It is further preferred that the long pipeline section and the inner wall of short sections are equipped with the recessed of the shape of threads to match with guiding tendon Slot.

It is further preferred that the long pipeline section can combined in any order with short sections.

The beneficial effects of the utility model：The communication tube has good ageing-resistant, fire resistance, and service life is long, and And can repeatedly be bent, the installation effectiveness of tubing can be effectively improved, the construction environment of various complexity is adapted to, reduces cost Input.

Specific embodiment

We are described further a kind of communication described in the utility model with polyethylene pipe with reference to attached drawing below.

As shown in Figures 1 and 2, a kind of communication polyethylene pipe of the present embodiment, including tube body 1, the tube body 1 includes Inner tube 2 and outer tube 3, said inner tube 2 are PE hoses, and the outer tube 3 is PE hard tubes, and the outer wall of said inner tube 2 is equipped with shape of threads Guiding tendon 21, the outer tube 3 are detachably connected by guiding tendon 21 and inner tube 2, and the outer wall of the outer tube 3 is equipped with fireproof material layer 31 and antiaging coatings 32, the inner wall of said inner tube 2 is equipped with wire sheathing 22, and the inside of the wire sheathing 22 is equipped with bullet Property filled layer 23, several penetration pipes 24 is equipped in the elastic packed layer 23, the inner wall of the penetration pipe 24, which is equipped with, increases sliding apply Layer 25, the outer tube 3 include a number of long pipeline section 4 and short sections 5.The long pipeline section 4 can random order group with short sections 5 It closes.The elastic packed layer 23 includes any one in silica gel, fire-resistant rubber, fire proofing firbre cloth.Pass through long pipeline section and short tube The various combination sequence of section so that tubing can cope with different construction environment needs, be bent accordingly, and pass through outer tube Effective protection internal structure improves construction efficiency.

In the present embodiment, the inner wall of the long pipeline section 4 and short sections 5 is equipped with the recessed of the shape of threads to match with guiding tendon 21 Slot 6.The connection for being conducive to long pipeline section and short sections is fixed, efficient, at low cost.

The scope of protection of the utility model is not limited to above example 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.
