Abstract
Disclosed is a double-wall corrugated pipe. The utility model relates to improvement of the double-wall corrugated pipe fitting. The double-wall corrugated pipe is composed of an inner layer, an outer layer and a heat preservation layer. The inner layer is a smooth and level pipe section. The surface of the outer layer is in a corrugated structure. The heat preservation layer is arranged between the inner layer and the outer layer in a tightly clamped mode. The double-wall corrugated pipe solves the problem that an existing double-wall corrugated pipe is bad in heat preservation performance. Due to the fact that the heat preservation layer is arranged between the inner layer and the outer layer, the heat preservation performance of the double-wall corrugated pipe is improved, and the heat preservation performance of an improved double-wall corrugated pipe is greatly enhanced. Due to the fact that the hear preservation performance of the double-wall corrugated pipe is enhanced, the double-wall corrugated pipe is not prone to frost crack in winter, and service of the double-wall corrugated pipe is prolonged.
Description
Technical field
The utility model relates to the improvement of double-wall corrugated pipe pipe fitting.
Background technique
Existing double-wall corrugated pipe is selected PVC＝polyvinyl chloride (PVC-U) extruding and moulding.Having the advantages such as inner wall smooth, discharge value be large, lightweight, corrosion-resistant, is the best substitute of the various tubing of embedded underground.But its heat insulating ability is poor, and the water capacity is easily frozen in the winter pipe, causes bellows by the generation of bursting by freezing phenomenon.
The model utility content
The utility model provides a kind of double-wall corrugated pipe, and the utility model has solved the poor problem of present double-wall corrugated pipe heat insulating ability.
For addressing the above problem, the utility model adopts following technological scheme: double-wall corrugated pipe of the present utility model is made of internal layer (1), outer (2), thermal insulation layer (3); Internal layer (1) is straight pipeline section, and outer (2) surface is corrugated structure, and internal layer (1) is clipped in the middle thermal insulation layer (3) closely with outer (2).
Advantage of the present utility model: owing between internal layer and skin, be provided with thermal insulation layer, therefore improved the thermal insulation property of bellows, greatly improved before the double-wall corrugated pipe heat insulating ability Performance Ratio after the improvement.Thermal insulation property has improved, so bellows is difficult for bursting by freezing winter, has also prolonged thus the working life of double-wall corrugated pipe.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: internal layer (1); Outer (2); Thermal insulation layer (3).
Embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, double-wall corrugated pipe is made of internal layer (1), outer (2), thermal insulation layer (3); Internal layer (1) is straight pipeline section, and outer (2) surface is corrugated structure, and internal layer (1) is clipped in the middle thermal insulation layer (3) closely with outer (2).
Thermal insulation layer (3) thickness is 1-10 centimetre.
Internal layer (1) is PVC＝polyvinyl chloride (PVC-U) with the material of outer (2), and the material of thermal insulation layer (3) is asbestos, and asbestos have good thermal insulation, are good thermal insulating materials, so the utility model double-wall corrugated pipe has good heat insulating ability.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
Claims (2)
1. double-wall corrugated pipe is characterized in that, is made of internal layer (1), outer (2), thermal insulation layer (3); Internal layer (1) is straight pipeline section, and outer (2) surface is corrugated structure, and internal layer (1) is clipped in the middle thermal insulation layer (3) closely with outer (2).
2. double-wall corrugated pipe as claimed in claim 1 is characterized in that, described thermal insulation layer (3) thickness is 1-10 centimetre.
