The utility model discloses a PE pipe requires lowerly to the production facility, is favorable to reduction in production cost, in addition, through being responsible for external coiling enhancement strip for PE pipe's weight gently just has better structural strength.

Description

A kind of PE pipe

Technical field

The utility model relates to a kind of pipe fitting, particularly a kind of PE pipe.

Background technology

PE (polyethylene) material, due to features such as its intensity are high, corrosion-resistant, nontoxic, is widely used in buildingBuild feedwater, construction drainage, buried drain pipe, building and heating, appendix, electrician and telecommunication protective casing,Industrial pipe, agricultural are used the fields such as pipe. Because it can not get rusty, so, be the reason that substitutes common molten iron pipeThink tubing. PE material has unique pliability, can effectively resist movement underground and end load.Current PE pipe adopts extrusion molding during fabrication conventionally, in the time that the larger PE of production caliber manages, needs largeThe extruder of type, cost of equipment is higher, manufactures more difficult. In addition, existing hollow PE pipe, in order to alleviateWeight and production cost, its tube wall is thinner, makes its structural strength poor, and fluid-resistant pressure and anti-impact force arePoor, need to improve pipe thickness and strengthen structural strength, make producing cost and PE pipe weight increase.

Utility model content

The utility model, in order to solve the problem of prior art, provides a kind of structural strength higher, fluid-resistantPressure capability is stronger, and the lower PE pipe of production cost.

Concrete technical scheme is as follows: a kind of PE pipe, comprise main pipe, and main pipe is by flexible board continuous reeling shapeBecome, described main pipe comprises multiple circle portion, and each circle portion comprises outer surface and inner surface, and circle portion both sides respectivelyBe the first edge and the second edge, outer surface is provided with the first breach at the first marginal position, and outer surface is secondMarginal position is provided with the first extension, and described inner surface is provided with the second breach, inner surface at the second marginal positionBe provided with the second extension at the first marginal position, described main pipe comprises multiple circle portion, first of adjacent turn portionExtension and the mutual clamping of the first breach, the second breach of adjacent turn portion and the mutual clamping of the second extension, PEPipe also comprises stiffener, and stiffener is wound on described main pipe's outer surface.

It is below attached technical scheme of the present utility model.

As preferred version, described stiffener is hollow tube.

As preferred version, in described hollow tube, be provided with supporting layer.

As preferred version, described flexible board, hollow tube and supporting layer are made by PE material.

As preferred version, described hollow tube is wound on main pipe in a spiral manner.

As preferred version, described the first breach and the second extension form stairstepping, described the second breach andThe first extension forms stairstepping.

Technique effect of the present utility model: PE pipe of the present utility model is lower to the requirement of production equipment, favourableIn reducing production costs; In addition, by the outer coiling stiffener of main pipe, make the weight of PE pipe light andThere is good structural strength, effectively promoted fluid-resistant pressure and the impact resistance performance of PE pipe.

Detailed description of the invention

Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but thisUtility model is not limited to listed embodiment.

As shown in Figures 1 to 5, the PE pipe 100 of the present embodiment comprises main pipe 1, and main pipe 1 is by flexibilityPlate 2 continuous reelings form, and described main pipe 1 comprises multiple circle portion 11, and each circle portion 11 comprises outer surface10 and inner surface 20. Circle portion 11 both sides are respectively the first edge 111 and the second edge 112, outer surface 10Be provided with the first breach 12 at the first marginal position, outer surface is provided with the first extension 13 at the second marginal position,Described inner surface 20 is provided with the second breach 14 at the second marginal position, and inner surface 20 is established at the first marginal positionThere is the second extension 15. The first extension 13 of adjacent turn portion 11 and the mutual clamping of the first breach 12, adjacentThe second breach 14 of circle portion 11 and the mutual clamping of the second extension 15. In the present embodiment, described the first breach12 and second extension 15 form stairstepping, described the second breach 14 and the first extension 13 form stairstepping.PE pipe also comprises stiffener 3, and stiffener 3 is wound on described main pipe's 1 outer surface. State technical schemeForm main pipe 1 by flexible board continuous reeling, can reduce the equipment requirement to extruder, reduce producing cost;In addition, by the outer coiling stiffener of main pipe, make that the weight of PE pipe is light and to have good structure strongDegree.

As shown in Figures 1 to 5, described stiffener 3 is hollow tube, in the time manufacturing, and can be by twoExtruder is Production Supervisor's body and hollow tube respectively, and required extruder is small-sized extruder, and equipment cost is lower,Simultaneously can improving production efficiency. In described hollow tube 3, be provided with supporting layer 4, thereby further promote PE pipeStructural strength. In the present embodiment, described flexible board, hollow tube and supporting layer are made by PE material. InstituteState hollow tube 3 and be wound in a spiral manner on main pipe 1, produce time, by coiler device by hollow tube 3Reel with flexible board 2, make flexible board 2 and hollow tube 3 mutually close simultaneously, the temperature retaining by selfIn conjunction with being fixed as finished product.

The PE pipe of the present embodiment is lower to the requirement of production equipment, is conducive to reduce production costs; In addition, logicalCross the outer coiling stiffener main pipe, the weight that makes PE pipe is light and have good structural strength, effectivelyFluid-resistant pressure and the impact resistance performance of PE pipe are promoted.

The above is only preferred embodiment of the present utility model, it should be pointed out that for the artThose of ordinary skill, not departing under the prerequisite of the utility model principle, can also make some improvementAnd retouching, these improvements and modifications also should be considered as protection domain of the present utility model.
