Abstract
The utility model discloses a kind of PE bellowss, including body, annular auxiliary tube has been poured on the tube wall of the body, the inner chamber of the annular auxiliary tube is hollow and sealing, the tangent plane of the annular auxiliary tube is ellipse, uniform in the annular auxiliary tube to set elastic, the adjacent of the annular auxiliary tube is provided with reinforcement, and reinforcement inlays the outer surface of tube wall of body.Pipe structure is being wrapped in using reinforcement, strengthen the intensity of body, it is not easily broken, reinforcement is completely embedded with body, ensureing the structure of same winding body, homogeneous tube external diameter of the present utility model is smaller, and the hollow setting of annular auxiliary tube, so that homogeneous tube includes inside and outside two tube walls, not only improve the ring flexibility of tubing but also reduce the proportion of homogeneous tube, nitrogen and the interior structure for setting elastic are filled in annular auxiliary tube, not only solve body stretching need stretching, extension position, more can Memorability contraction body.
Description
Technical field
The utility model is related to construction apparatus technical field, specially a kind of PE bellowss.
Background technology
It is well known that bellows more be applied to urban construction, residential quarters ground water drainage, blow-off line, highway,
Irrigation conveying in the conveying and farmland water of high-tension cable, harbour, oil, chemical industry, mine for fluid etc., is applied especially to
Fuel gas transmission pipeline and artificial coal gas Natural Gas Conversion improvement project, bellows can fundamentally solve combustion gas metal and introduce pipe
Corrosion failure problem, but its inside pipe wall is smooth flat, or existing defects.Combustion gas improvement project is to involve thousand ten thousand
Family engineering.Need to change pipeline, dig pit, stemming operation expends big, and welding destroys road.
Traditional HDPE bellowss are all to wind small bellows again on smooth matrix, so as to improve the strong of product
Degree.But, existing matrix is closely entwined by extruding unit, and extrudes the gap between unit and unit very
It is small, so the matrix surface after shaping is substantially very smooth, and bellows is wound again in the smooth pipe surface, the finished product made
Ring stiffness itself and ring flexibility be not good, in addition overall heavier and unfavorable storage and transport, and entirety is thicker and influences bearing capacity
And turn.
Utility model content
The purpose of this utility model is to provide a kind of PE bellowss, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of PE bellowss, including body, it is described
Annular auxiliary tube is poured on the tube wall of body, the inner chamber of the annular auxiliary tube is hollow and sealing, the annular auxiliary tube
Tangent plane be ellipse, be equidistantly provided with elastic in the annular auxiliary tube, the adjacent of the annular auxiliary tube is provided with strengthening
Muscle, and reinforcement inlays the outer surface of body.
It is preferred that, nitrogen is filled in the annular auxiliary tube, and annular auxiliary tube section transverse is more than the width of body
Degree.
It is preferred that, the reinforcement is PP entity pipelines, and the outside of the reinforcement is provided with cover layer.
It is preferred that, the elastic is spring, and quantity is no less than 3.
Compared with prior art, the beneficial effects of the utility model are：Pipe structure is being wrapped in using reinforcement, strengthened
The intensity of body, is not easily broken, and reinforcement is completely embedded with body, is ensureing the structure of same winding body, the utility model
Homogeneous tube external diameter it is smaller, and the hollow setting of annular auxiliary tube so that homogeneous tube includes inside and outside two tube walls, both improves pipe
The ring flexibility of material is reduced again fills nitrogen and the interior structure for setting elastic in the proportion of homogeneous tube, annular auxiliary tube, not only solve
The stretching, extension position that body stretching needs, more can Memorability contraction body, the PE bellowss are simple in construction, reasonable in design and real
With the scope of application is wider.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the annular auxiliary tube structural representation of the utility model.
In figure：1 body, 2 annular auxiliary tubes, 3 reinforcements, 4 elastics.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of PE bellowss, including body 1, the pipe
Annular auxiliary tube 2 is poured on the tube wall of body 1, the inner chamber of the annular auxiliary tube 2 is hollow and sealing, the annular auxiliary tube
2 tangent plane is that elastic 4 is uniformly set in ellipse, the annular auxiliary tube 2, and the adjacent of the annular auxiliary tube 2, which is provided with, to be added
Strengthening tendons 3, and reinforcement 3 inlays the outer surface of body 1.
The reinforcement 3 is PP entity pipelines, and the outside of the reinforcement 3 is provided with cover layer, and cover layer is to a certain degree
On can protect overall structure, sun-proof side rubs, cover layer can be layer of varnish, layer of varnish can be with the function such as anti-oxidation, the ring
Nitrogen is filled in shape auxiliary tube 2, or fills the inert gases such as helium, neon, argon gas, xenon, radon gas, such gas is stable,
And function needs are met, and the annular section transverse of auxiliary tube 2 is more than the width of body 1, interior empty annular auxiliary tube 2 makes pipe
Body 1 increases by two layers of tube wall, while protection, preferably hides and stretches position, the elastic 4 is spring, and quantity is not
Less than 3, the elastic 4 can also be elastic rubber column etc., because going function to be to need elasticity, meet the knot of elasticity
Structure or material, can be added as needed on changing, the quantity of elastic 4 is set, and be to strengthen the elasticity and stability of its result, institute
With can appropriate adjustment quantity as needed, nitrogen and elastic 4 can do Memorability retraction fortune to annular auxiliary tube 2 simultaneously
It is dynamic, make body 1 more flexible.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
