Abstract
The utility model relates to a water drainage pipe, in particular to a hollow wall inner spiral silencing water drainage pipe; wherein, the pipe wall comprises an internal and an external layer. The two layers are connected by splice bars, and the pipe wall of the internal pipe is provided with a spiral groove. The utility model has the advantages of having rational design, novel structure, great sound insulation performance, reducing material consumption, enhancing pipe intensity and having good environment protection. The utility model is applicable to be used in a plurality of occasions, more particularly in house-drainage pipe system.
Description
Technical field:
The utility model relates to a kind of waste pipe, specifically a kind of hollow wall internal spiral noise reduction waste pipe.
Background technique:
According to the knowledge of the applicant, at present, the U-PVC pipe generally is divided into solid wall pipe and foaming pipe, because inner tube wall is smooth, easily produces noise during draining.Solid wall pipe does not only have sound insulation but also do not have erasure effect, and the real cost of material height of wall; The foaming pipe has certain soundproof effect on certain degree, but effect is not clearly.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provides a kind of structure and technology simple, and sound insulation, performance muffler are good, the waste pipe that cost is low.
The technological scheme that its technical problem that solves the utility model adopts is a kind of waste pipe, and it is inside and outside two-layer to it is characterized in that tube wall divides, hollow, and two interlayers are connected by connecting tendon, and inner layer tube wall is established spiral chute.
The utility model adopts said structure, and soundproof effect is good, has reduced material consumption, has strengthened tubing intensity, and environment protection effect is good.
Description of drawings:
Accompanying drawing is a kind of structural representation of the present utility model, also is embodiment's schematic representation.
The utility model will be further described below in conjunction with accompanying drawing;
Fig. 1 is a plan view.Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
From Fig. 1 and Fig. 2 as can be seen, a kind of waste pipe of the utility model, tube wall divides inside and outside two-layer: outer wall 1 and inwall 3.Hollow.3 of outer wall 1 and inwalls are connected by connecting tendon 2.Inwall 3 adopts the multi-head spiral structure, and promptly spiral chute 4.The utility model adopts three layers of composite co-extruding technology, and advanced technical recipe is equipped with the plug co-extruding machine head that has spiral chute and energy uniform rotation, has very strong sound insulation silencing function, has fundamentally solved drowning noise problem.
The utility model is reasonable in design, novel structure, and the combination property height, cost is low, is suitable for multiple occasion and uses.Be particularly suited for the indoor drainage pipe system.
Claims (2)
1 one kinds of waste pipes, it is inside and outside two-layer to it is characterized in that tube wall divides, hollow, two interlayers are connected by connecting tendon, and inner layer tube wall is established spiral chute.
2 a kind of waste pipes according to claim 1 is characterized in that said spiral chute is a multi-head spiral.
