Abstract
The utility model discloses a kind of double wall corrugated high-density polyethylene pipes, comprise level and smooth inner wall tube and undulatory outer wall pipe, be connected by rubber ring between described inner wall tube and outer wall pipe; The utility model has the advantage of: not only inside and outside two-layer tube wall combines firmly, enhances entire compression intensity, and elasticity is large, and tortuosity is high, improves quality of product.<b/>
Description
Technical field
The utility model relates to a kind of bellows, specifically a kind of double wall corrugated high-density polyethylene pipes, belongs to bellows field.
Background technique
At present, double-wall corrugated pipe is applied to the association areas such as building, communication, agricultural just more and more with the performance of its excellence, the double-wall corrugated pipe of prior art is generally made up of inside and outside two-layer tube wall, a cavity is formed between two-layer tube wall inside and outside it, to strengthen the entire compression intensity of pipeline, but in use, inside and outside two-layer tube wall is usually easily thrown off, and do not have the object strengthening pipeline entire compression intensity, bring hidden danger to pipework construction.Name is called that " double-wall corrugated pipe " application number is that the Chinese utility model patent of " 201120208139.7 " discloses a kind of double-wall corrugated pipe, by ripple parietal layer, tie layer, ripple space, pipe space, pipe parietal layer forms, pipe space is the isometrical space pipeline surrounded by pipe parietal layer, inner-walls of duct is smooth, the outer installment ripple parietal layer of pipe parietal layer, ripple parietal layer is corrugated distribution along the axial direction in pipe space, the crest place of ripple parietal layer is to pipe parietal layer outer lug, ripple space is formed between the ripple parietal layer of convex portion and pipe parietal layer, the trough place of ripple parietal layer is recessed to pipe parietal layer, between the trough recess of ripple parietal layer and pipe parietal layer, tie layer is set.But after adopting this kind of structure, the elasticity of its bellows is less, and not flexible, elongation reduces.
Model utility content
In order to solve the problem, the utility model devises a kind of double wall corrugated high-density polyethylene pipes, and not only inside and outside two-layer tube wall combines firmly, enhances entire compression intensity, and elasticity is large, and tortuosity is high, improves product strength, extends working life.
The technical solution of the utility model is:
A kind of double wall corrugated high-density polyethylene pipes, comprises level and smooth inner wall tube and undulatory outer wall pipe, is connected between described inner wall tube and outer wall pipe by rubber ring, not only inside and outside two-layer tube wall combines firmly, enhance entire compression intensity, and elasticity is large, tortuosity is high.
Be provided with multiple cavity in the sidewall of described outer wall pipe, break because of extruding for bellows wall layers, improve product strength, extend working life.
Further, described rubber ring is oval.
Further, described joint is positioned at the trough place of described outer wall pipe.
Further, described outer wall pipe has corrugated projection, and running through between each corrugated projection has axial connecting tendon, and connecting tendon is multiple, and annular spread is on outer wall pipe, adds the intensity of its entirety, and structure is simple, easily manufactured.
The utility model has the advantage of: not only inside and outside two-layer tube wall combines firmly, enhances entire compression intensity, and elasticity is large, and tortuosity is high, improves product strength, extends working life.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of double wall corrugated high-density polyethylene pipes, comprise level and smooth inner wall tube 1 and undulatory outer wall pipe 2, be connected by rubber ring 3 between described inner wall tube 1 and outer wall pipe 2, not only inside and outside two-layer tube wall combines firmly, enhance entire compression intensity, and elasticity is large, tortuosity is high, and described rubber ring 3 is oval; Described joint is positioned at the trough place of described outer wall pipe 2.Be provided with multiple cavity 4 in the sidewall of described outer wall pipe, break because of extruding for bellows wall layers, improve product strength, extend working life.
Described outer wall pipe 2 has corrugated projection, and running through between each corrugated projection has axial connecting tendon, and connecting tendon is multiple, and annular spread is on outer wall pipe, adds the intensity of its entirety, and structure is simple, easily manufactured.
