Abstract
The utility model provides a three-wall corrugated pipe, comprising a smooth inner wall (1), a ring-shaped corrugated middle wall (2), and an outer wall (3) covering the outer surface. A wave hollow and a wave peak of the middle wall (2) are respectively connected to the inner wall (1) and the outer wall (3). The three-wall corrugated pipe is advantageous in that the three-wall corrugated pipe inherits the advantages of a double-wall corrugated pipe and has the advantages of a circular pipe; the ring stiffness is improved by over twice compared with that of a double-wall corrugated pipe having the same specification; the inner and outer walls are smooth, and the connection is convenient and reliable.
Description
Technical field
The utility model belongs to plastic tube structure field, particularly relates to a kind of three wall bellowss.
Background technique
At present double-wall corrugated pipe progressively has been applied to communication, building, the city fields such as irrigation of having stable political situation with its excellent performance.But existing double-wall corrugated pipe end face is the circular arc crest, and after tubing was stressed, the discontinuity of circular arc crest made bellows in certain diameter distortion amount, can only bear less ambient pressure, the overall loop rigidity that causes tubing a little less than.
And common solid wall pipe, though ring stiffness is higher, it expends too much material, so can combine the characteristics of double-wall corrugated pipe and solid wall pipe to carry out the improvement of pipe structure.
The model utility content
The purpose of the utility model is to provide a kind of material and three high wall bellowss of ring stiffness saved.
In order to realize above-mentioned model utility purpose, the technological scheme of employing is following.
A kind of three wall bellowss comprise level and smooth inwall, undulatory mesospore, and the outer wall that covers outer surface ringwise, and the trough of said mesospore is connected with inner and outer wall respectively with crest.
The inwall and the mesospore of the utility model are equivalent to double-wall corrugated pipe; Possess existing double-wall corrugated pipe and save the advantage of material; Outer wall then covers the outer surface of double-wall corrugated pipe; Make the inside and outside wall of three wall bellowss be slick and sly real parietal layer, overcome double-wall corrugated pipe and caused the more weak deficiency of ring stiffness, improved the whole ring stiffness of tubing because of the discontinuity of circular arc crest.
In the technique scheme, said outer wall is level and smooth plastic layer.
Said mesospore comprises the uniform bellows segment in a plurality of intervals, is smooth section between the bellows segment, and said bellows segment cross section adopts triangle, rectangle, trapezoidal or arc.
The bellows segment of said mesospore can be provided with the enhancing steel band of correspondingly-shaped, with the intensity of further enhancing tubing.
Further, can perk in order to ensure the embedded enhancing steel band of mesospore, the smooth section of said mesospore can also compress through the spirality steel band.
Said inwall of the utility model and mesospore are for adopting the double-wall corrugated pipe of PE material extruding and moulding, and said outer wall is extruded the pipe that is coated in double-wall corrugated tube outer surface for adopting the PE material.
The three wall bellowss of the utility model have been inherited the advantage of double-wall corrugated pipe, have the advantage of pipe simultaneously.Promoted more than the twice with the ring stiffness of the double-wall corrugated pipe of equal specification, inside and outside wall is smooth, and is easy to connect reliable.
The utlity model has following advantage.
1, through detecting; The ring stiffness of the three wall bellowss of the utility model reaches more than the 29.1KN/m2; Compare the requirement of 16.9 KN/m2 of the double-wall corrugated pipe of ad eundem; The ring stiffness of this kind tubing has improved more than 72.1%, thereby has strengthened the resistivity of pipeline to the soil load, makes the use occasion of this kind tubing more extensive.
2, the outer tube of the three wall bellowss of the utility model adopts the pipe form, strengthens the performance of resisting environmental stress and cracking greatly.
3, the three wall bellowss of the utility model, are compared with common bellows so the connection of multistage tubing can be adopted existing solid wall pipe Placement etc. because inside and outside wall all is level and smooth, install to connect simply fast.
4, the three wall bellowss of the utility model with compare with the solid wall pipe of material specification, can practice thrift the raw material about half, cost of production is low.
5, the pipe material by adopting PE material of the utility model has good low-temperature resistance, shock resistance, and chemical stability is good, longer service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The structure of the utility model is a kind of three wall bellowss of simple structure shown in accompanying drawing 1, this three walls bellows is made up of level and smooth inwall 1, annular corrugated mesospore 2 and level and smooth outer wall 3.This three walls bellows adopts PE double-wall corrugated pipe outer wall to apply the extruding production line production of pipe; Production line is extruded the plastics of fusion through two single screw extrusion machines; Through getting into the double-wall corrugated pipe molding machine behind the mould; Through after the cooling of spraying box, the double-wall corrugated pipe moulding is again through becoming three wall bellowss behind the outer wall coating PE pipe layer.
