A kind of wear-resisting PVC double-wall corrugated pipeTechnical field
The utility model relates to tubing field, particularly relates to a kind of wear-resisting PVC double-wall corrugated pipe.
Background technique
The usual undulate structure of outer wall of the bellows of prior art, in the process of transporting or use, easily produces friction between adjacent bellows or between bellows and ground, thus the outer wall of wearing and tearing bellows.And the tube wall of bellows is general thinner, easy worn out bellows when rubbing violent, makes this bellows use.
Model utility content
Problem to be solved in the utility model is: propose a kind of wear-resisting PVC double-wall corrugated pipe, and it has the good feature of wear resistance.
The utility model technical solution problem adopts following technological scheme:
A kind of wear-resisting PVC double-wall corrugated pipe, comprise inwall, outer wall and wearing layer, described inwall is smooth walls, and described outer wall is bellows wall, the coated one deck wearing layer of described outer wall outer surface, the part rounding off of described wearing layer between crest and trough.
As preferably, described wearing layer material is polyurethane elastomer.
As preferably, described wearing layer thickness d≤3mm.
The beneficial effects of the utility model are: by arranging at Double-wall PVC bellows outer wall outer surface the wear resistance that one deck wearing layer increases Double-wall PVC bellows.
Accompanying drawing explanation
Fig. 1 is the main pseudosection of the utility model.
Number in the figure: 1 is inwall, 2 is outer wall, and 3 is wearing layer.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to Fig. 1, the utility model proposes a kind of wear-resisting PVC double-wall corrugated pipe, comprise inwall 1, outer wall 2 and wearing layer 3, described inwall 1 is smooth walls, described outer wall 2 is bellows wall, the coated one deck wearing layer 3 of described outer wall 2 outer surface, the part rounding off of described wearing layer 3 between crest and trough.
When specific design, described wearing layer 3 material is polyurethane elastomer.
When specific design, described wearing layer 3 thickness d≤3mm.
The utility model proposes a kind of wear-resisting PVC double-wall corrugated pipe, it comprises inwall 1, outer wall 2 and wearing layer 3, described inwall 1 is smooth walls, described outer wall 2 is bellows wall, the coated one deck wearing layer 3 of described outer wall 2 outer surface, and the material of wearing layer 3 is the polyurethane elastomer with superior abrasion resistance and fatigue resistance, and the part rounding off of wearing layer 3 between crest and trough, described wearing layer 3 thickness d≤3mm, like this under the prerequisite not affecting Double-wall PVC bellows bending properties, the wear resistance of Reinforced PVC upper wall bellows.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
