Abstract
The invention provides a three-wall corrugated tube comprising a smooth inner layer (1), an annular middle corrugated layer (2) and an outer layer (3) covered on an outer surface, wherein the wave trough and the wave crest of the middle layer (2) are respectively connected with the inner layer (1) and the outer layer (3). The three-wall corrugated tube provided by the invention inherits the advantages of a double-wall corrugated tube and also has the advantages of a round tube. The ring stiffness of the three-wall corrugated tube is twice more than that of the double-wall corrugated tube with the same specification, and the three-wall corrugated tube has smooth inner and outer walls and is convenient and reliable in connection.
Description
Technical field
The invention belongs to plastic tube structure field, particularly relate 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.
Summary of the invention
The object of the present invention is to provide a kind of material and three high wall bellowss of ring stiffness saved.
In order to realize the foregoing invention purpose, the technological scheme of employing is following.
A kind of three wall bellowss comprise level and smooth internal layer, undulatory mesosphere, and the skin that covers outer surface ringwise, and the trough in said mesosphere is connected with outer with internal layer respectively with crest.
Internal layer of the present invention and mesosphere are equivalent to double-wall corrugated pipe; Possess existing double-wall corrugated pipe and save the advantage of material; Outer then cover 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 skin is level and smooth plastic layer.
Said mesosphere 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 in said mesosphere 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 in mesosphere, the smooth section in said mesosphere can also compress through the spirality steel band.
Internal layer according to the invention and mesosphere are for adopting the double-wall corrugated pipe of PE material extruding and moulding, and said skin is extruded the pipe that is coated in double-wall corrugated tube outer surface for adopting the PE material.
Three wall bellowss of the present invention 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 present invention has following advantage.
1, through detecting; The ring stiffness of three wall bellowss of the present invention 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 three wall bellowss of the present invention adopts the pipe form, strengthens the performance of resisting environmental stress and cracking greatly.
3, three wall bellowss of the present invention, 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, three wall bellowss of the present invention with compare with the solid wall pipe of material specification, can practice thrift the raw material about half, cost of production is low.
5, pipe material by adopting PE material of the present invention has good low-temperature resistance, shock resistance, and chemical stability is good, longer service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
Structure of the present invention 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 the double-wall corrugated outer tube layer of PE 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 skin coating PE pipe layer.
