Abstract
The utility model discloses a steel reinforcing polyethylene winding pipe, which comprises a pipeline inner wall (1) spirally rolled by a plastic plate belt. At least a layer of steel net (2) covers the outer side of the pipeline inner wall (1); a polyethylene layer (3) covers the outer side of the steel net; a strip-like plate (4) with a convex rib part (6) is arranged outside the polyethylene layer; a steel belt (8) is wound between the convex rib parts of the strip-like plate (4); a polyethylene layer (7) covers the outer side of the plate (4) and the steel belt (8) so that a smooth surface is formed on the outer wall of the pipeline. The utility model has the beneficial effects that the pipeline is spirally rolled by the formed plate belt; the diameter of the pipeline can be very large; a great quantity of plastic has no need to be extruded in a rolling process so as to reduce energy consumption; moreover, the capability of the pipeline for bearing inner pressure is increased by the steel net arranged in the pipe wall; the ring rigidity of the pipeline is realized by the steel belt (8); and the pipeline has good forming effect and low cost.
Description
Technical field
The utility model relates to a kind of winding polyethylene pipe, the winding polyethylene pipe that specifically a kind of steel strengthens.
Background technique
The existing polyethylene pressure tube of producing with extrusion process, in case that Guan Jing makes when big is just very difficult, and yield rate is low, the cost height, pressure-bearing is not high yet.
The model utility content
The purpose of this utility model is: provide a kind of easy processing at the deficiencies in the prior art, the steel of quality of finished product good strengthens polytene corrugated tube.
The technical solution of the utility model is:
A kind of steel strengthens the winding polyethylene pipe, comprise inner-walls of duct by plastics strip helical coil system, at least be surrounded by one deck steel mesh in the described inner-walls of duct outside, coat polyethylene layer in the steel mesh outside, in the polyethylene layer outside is the banded sheet material with protruding spine, between the protruding spine of described banded sheet material, be wound with steel band, coat polyethylene layer, make pipeline outer wall form smooth surface in the outside of sheet material and steel band.
As optimal way, the spine of described sheet material is a hollow.
As optimal way, outside inner-walls of duct, be surrounded by steel mesh more than one deck.
As optimal way, described steel band top is a circular arc.
The beneficial effects of the utility model are: pipeline is rolled by the strip spiral of moulding, the diameter of pipeline can be done very greatly, in the process of rolling, need not a large amount of extrusion plastics, reduced energy consumption, and the steel mesh that is provided with in tube wall has increased the ability of pressing in pipeline bears, and the pipeline forming effect is good, and pipe ring rigidity is realized by winding steel, cost is low, the yield rate height.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a half sectional view of the present utility model;
Fig. 2 is the cross-sectional view of banded sheet material.
Wherein, 1 is inner-walls of duct, and 2 is steel mesh, and 3 is the polyethylene layer in the steel mesh outside, and 4 is banded sheet material, and 5 is projection, and 6 is spine, and 7 is the polyethylene layer in the banded sheet material outside, and 8 is steel band.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in the figure, a kind of steel strengthens the winding polyethylene pipe, comprise inner-walls of duct 1 by plastics strip helical coil system, be surrounded by one deck steel mesh 2 in the described inner-walls of duct outside, according to different requirements to pipeline strength, also can be at the more multi-layered steel mesh of inner-walls of duct outside bag, coat polyethylene layer 3 in the steel mesh outside, in the polyethylene layer outside is banded sheet material 4, between the protruding spine of described banded sheet material, be wound with steel band, the outside at sheet material and steel band coats polyethylene layer, makes pipeline outer wall form smooth surface.The spine 6 of described sheet material 4 is a hollow, described steel band 8 tops are circular arc, on the banded sheet material 4 spine 6 is arranged, projection 5 is arranged in the spine 6, the outside at described banded sheet material coats polyethylene layer 7, the two ends of steel band 8 are stuck in the downside on base, and described spine 6 is the spine of hollow, and the cross section of described spine 6 is rectangle or squares of a hollow.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
