Description
Technical field
The utility model belongs to plastic products technology field, more particularly to a kind of protection of proof stress polyethylene power communication
Pipe.
Background technology
Now, the application of plastic pipe and its universal, kind many, e.g., by the material point of plastic pipe：Polyethylene pipe
Material, polypropylene pipe, polychloroethylene pipes, glass fiber reinforced plastics composite material tubing, and other materials tubing, by purposes point：Electric power
Tubing, communication tubing, municipal blowdown tubing, rainwater tubing, running water pipe, civil buildings tubing etc., plastic pipe strength character
Requirement, corrosion-resistant etc. can be met, and it is easy to use, and raw material supply is sufficient, easy construction etc. advantage, so, plastics
Tubing is popularized very much, but, plastic pipe also has many weakness or a defect, such as field use sunshine with drench with rain, winter and summer
The severe cold and high temperature in season so that tubing easily aoxidizes, aging, and service life is greatly shortened, also, plastic pipe and metal material
Material, timber etc. are the same, also there is a material stress problem, and in process of production, the stress problem of plastic pipe processes bad, pipe
Material can occur the phenomenon for ftractureing at a slow speed or rupturing, and largely effect on service life, so, resolve plastic pipe environmental stress resistance slow
Fast problem of Cracking is extremely important.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of proof stress polyethylene electric power
Communications protection pipe, the shaft design, material selection from polyvinyl piping materials is started with, and solves the problems, such as tubing proof stress.
The purpose of this utility model by following technical solution completing, protect by this proof stress polyethylene power communication
Pillar, including body, described body is made up of body internal layer, body middle level, body outer layer, is set on the outer wall of the body internal layer
There are a circle several circular arcs contact convex surfaces, several circular arcs contact convex surfaces are in waiting the outer wall that is distributed in the body internal layer
On；The inwall in the body middle level is provided with a circle several circular arcs contact concave surfaces, several circular arcs contact concave surfaces in etc.
It is distributed on the inwall in the body middle level, and is in corresponding distribution with circular arc contact convex surface；Described body internal layer is located at
In body middle level, and convex surface is contacted by circular arc contact concave surface with circular arc and be mutually combined with each other, the setting outside body middle level
There is body outer layer, the body internal layer, be fabricated by by three-layer co-extruded extruding machine co-extrusion between body middle level, body outer layer.
Preferably, described body internal layer, body middle level, the thickness ratio of body outer layer are：2:6:2.
Preferably, described body internal layer is made up of PE100 polythene materials.
Preferably, described body outer layer is made up of PE100 polyethylene and the material modified of EVA resin.
The beneficial effects of the utility model are：1st, polyethylene three-layer pipe body structure is manufactured by three-layer co-extruded technological design,
Eliminate a part of tubing stress；2nd, tubing circular arc internal layer is set, tubing ductile strength is improved；3rd, modified polythene tube outer layer
Material, increases the content of vinyl acetate polyester, improves tubing toughness, the technical scheme of impact resistance, substantially increases tubing
Stress crack resistance performance, solves the problems, such as cracking at a slow speed or slow crack that polyvinyl piping materials environmental stress resistance causes, improves and produces
Product life-span and product inherent quality.
