Description
Technical field
The utility model relates to a kind of bellows, particularly relates to a kind of HDPE reinforcement enhancement mode and is wound around bellows.
Background technique
High density polyethylene (HDPE) (HDPE) bellows is for main raw material adds necessary additive with high density polyethylene (HDPE) (HDPE), through the tubing with ripple struction that extruding and moulding mode processes, inwall flat smooth, outer wall ripple, inside and outside wall is hollow and the ring structure of tight weld, has corrosion-resistant, long service life, inner wall smooth, flowage friction resistance is little, the advantages such as easy integrated molding.
Due to material restriction, existing HDPE corrugated pipe ring rigidity is inadequate, and Long-Time Service easily produces breakage or cracking, needs to make regular check on, additionally consumes man power and material, and is not easy to make large diameter pipeline.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of HDPE reinforcement enhancement mode and is wound around bellows, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of HDPE reinforcement enhancement mode is wound around bellows, wherein, comprise bellows pipe racks, described bellows pipe racks spiral winding becomes tubulose, described bellows pipe racks is provided with the projection of hollow, the cross section semicircular in shape structure of described projection, plug one section of arc-shaped steel in the projection of described semicircular structure respectively tough, in described projection, vacancy is provided with supporting plate structure.
Above-mentioned HDPE reinforcement enhancement mode is wound around bellows, and wherein, described supporting plate structure comprises one piece of dunnage, and described dunnage is perpendicular to described pipe racks and be arranged in the neutral position in the vacancy of the projection of described semicircular structure.
Above-mentioned HDPE reinforcement enhancement mode is wound around bellows, and wherein, described supporting plate structure comprises two pieces of dunnages, and described dunnage is perpendicular to described pipe racks and be arranged in 1/3rd positions in the vacancy of the projection of described semicircular structure in parallel to each other separately.
Above-mentioned HDPE reinforcement enhancement mode is wound around bellows, and wherein, the lap-joint of the spiral winding of described pipe racks is bonded together by welding mode.
Compared with the prior art, the beneficial effects of the utility model are:
Replace extruded type to produce bellows with wrap style, easily make large diameter pipeline, the hollow design of the projection of semicircle pipe racks is supporting plate structure, and be plugged in HDPE tubing by tough for steel, can improve the ring stiffness of pipeline, pipe racks lap-joint adopts welding mode, and pipeline is not easy to crack.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 a is the example structure schematic diagram that the utility model HDPE reinforcement enhancement mode is wound around bellows;
Fig. 1 b is the structural representation that the utility model HDPE reinforcement enhancement mode is wound around another embodiment of bellows.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
With reference to shown in Fig. 1 a and Fig. 1 b, the utility model HDPE reinforcement enhancement mode is wound around bellows and comprises bellows pipe racks 1, bellows pipe racks 1 spiral winding becomes tubulose, bellows pipe racks 1 is provided with the projection 2 of hollow, the cross section semicircular in shape structure of protruding 2, plug one section of arc-shaped steel tough 3 in the projection 2 of semicircular structure respectively, the curvature of arc-shaped steel tough 3 is consistent with the curvature of semicircular structure, and in protruding 2, vacancy is provided with supporting plate structure.
In one embodiment, referring to Fig. 1 a, supporting plate structure comprises one piece of dunnage 4, and dunnage 4 is perpendicular to pipe racks 1 and be arranged in the neutral position in the vacancy of the projection 2 of semicircular structure.Such structure can make semicircular protruding 2 structures more firm, can bear stronger pressure.
In another embodiment, referring to Fig. 1 b, supporting plate structure comprises two pieces of dunnages 4, and dunnage 4 is perpendicular to pipe racks 1 and be arranged in 1/3rd positions in the vacancy of the projection 2 of semicircular structure in parallel to each other separately.Such structure can make semicircular protruding 2 structures more firm, can bear stronger pressure.
Above-mentioned two kinds of supporting plate structures, when pipeline receives pressure, make internal stress to disperse more equably, add ring stiffness and the working life of pipeline.The material of dunnage 4 can be selected consistent with pipe racks 1.
It is pointed out that the lap-joint of the spiral winding of the pipe racks 1 in the utility model is bonded together by welding mode, with the intensity of the mutual overlap of reinforcing phase.
As can be seen from above-described embodiment, advantage of the present utility model is:
Replace extruded type to produce bellows with wrap style, easily make large diameter pipeline, the hollow design of the projection of semicircle pipe racks is supporting plate structure, and be plugged in HDPE tubing by tough for steel, can improve the ring stiffness of pipeline, pipe racks lap-joint adopts welding mode, and pipeline is not easy to crack.
Be described in detail specific embodiment of the utility model above, but the utility model is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications and substitute also all among category of the present utility model.Therefore, not departing from equalization conversion done under spirit and scope of the present utility model and amendment, all should be encompassed in scope of the present utility model.
