Description

A kind of composite enhanced pipeline configurations of PE

Technical field

It the utility model is related to compound pipeline complex pipeline, pipe structure technical field, specially a kind of composite enhanced pipeline knots of PE Structure.

Background technology

PE pipes are light, smooth with its（Coefficient of friction is small）, non-scaling, do not tie it is cured, do not condense, corrosion resistance and good, without dirt Dye（Drinking water can be conveyed）, low-resistance, insulate, have good pliability and impact resistance, have good wearability, service life The advantages that long, easy for installation, is applied than wide on current pipeline market.

Designer of the present utility model has found that PE compound pipeline complex pipelines have shortcomings, such as low intensity in use（Typically make With pressure≤1.0MPa）, poor rigidity, linear expansion coefficient is big, creep etc. be present.It is caused to apply at the larger place of pressure, Service life is shorter, also, its outer wall is easily damaged by the sharp objects pressure such as stone, outer wall, pipeline the hidden of rupture is present Suffer from.

Then, inventor in view of this, adhere to the relevant industries for many years it is abundant design and develop and the experience of actual fabrication, Improvement is studied for existing structure and missing, there is provided a kind of composite enhanced pipeline configurations of the good PE of compressive property, with Phase reaches the purpose with more more practical value.

Utility model content

The purpose of this utility model is to provide a kind of composite enhanced pipeline configurations of PE, to solve in above-mentioned background technology The problem of compressive property is poor be present in the current PE compound pipeline complex pipelines used proposed.

To achieve the above object, the utility model provides following technical scheme：A kind of composite enhanced pipeline configurations of PE, bag Include

PE outer layers, external hot melting glue-line, thin-walled steel plate, interior hot melt adhesive layer, PE internal layers, stiffener, steel plate hole and salient point；

The inwall of the PE outer layers is connected by external hot melting glue-line with thin-walled steel plate, and the inwall of the thin-walled steel plate passes through Interior hot melt adhesive layer is connected with PE internal layers, and the outer wall of the PE outer layers is provided with salient point.

Preferably, it is surround on the thin-walled steel plate and is welded with stiffener.

Preferably, the salient point and the integral structure that PE outer layers are identical material.

Preferably, steel plate hole is uniformly offered on the thin-walled steel plate.

Compared with prior art, the utility model has the advantages that：

1. the utility model wraps up one layer of thin-walled steel plate by double-deck PE pipes, because the mechanical strength of steel is about the 10 of PE pipes Times or so, using the excellent mechanical strength of steel plate, creep resistance and the impact resistance of pipeline are improved, and in the outer of thin-walled steel plate Around stiffener is welded with wall, the compressive property of pipeline is further improved, is experimentally confirmed, it is of the present utility model allowable Zernike annular polynomial improves more than 1 times than common PE composite plastic pipe.

2. the utility model is provided with the salient point of integral type on the outer wall of PE outer layers, stone in laying irrigation canals and ditches can be effectively reduced The sharp objects such as block are destroyed to caused by pipeline, also, it is axial force that the pressure in the external world is decomposed a part by salient point, reduces pipeline The potential safety hazard of rupture, improve its service life.
