Abstract

The utility model discloses a silencing type PVC drainage pipe structure. The silencing type PVC drainage pipe structure comprises a PVC drainage pipe. Guiding protruding arrises capable of segmenting and guiding water flow are evenly arranged on the inner wall of the PVC drainage pipe. Dense protrusions and pits are formed in the portions, between the guiding protruding arrises, of the inner wall of the PVC drainage pipe. The cross section of each guiding protruding arris is in a triangle shape. The height of the guiding protruding arrises ranges from five millimeters to fifteen millimeters. According to the silencing type PVC drainage pipe structure, the guiding protruding arrises capable of segmenting and guiding water flow and the dense protrusions and the dense pits are arranged on the inner wall of the PVC drainage pipe, the guiding protruding arrises can segment and guide flowing water in the drainage pipe, the guiding protruding arrises, the protrusions and the pits in the inner wall can absorb water energy and reduce the speed of the flowing water impacting the drainage pipe, and consequently water draining noise can be reduced.

Description

A kind of noise cancelling type PVC drain structure

Technical field

The utility model relates to pvc pipe part technical field, relates in particular to a kind of noise cancelling type PVC drain structure.

Background technique

Pvc pipe part is through extruding or a kind of plastic pipe of molding and forming take PVC＝polyvinyl chloride (PVC) resin as main raw material.Lightweight, corrosion-resistant, the advantage such as resistance to water-flow is little, energy saving, installation is fast, cost is low that pvc pipe part has, be subject to wideling popularize application, remarkable benefit, be widely used in cities and towns tap water water delivery water supply project, Discussion on architecture water supply project, industrial and mining enterprise's water supply project, buried fire fighting supply engineering, irrigation and water conservancy burial conveyance of water irrigation engineering, gardens garderning green water supply project, culture fishery water supply and drainage engineering etc., and obtain good economic benefit and social benefit.

But the drainage noise of existing common PVC waste pipe is higher than traditional cast iron tube, add that the soundproof effect of cast-in-situ floor is poor, user can obviously feel and the noise of drainage pipe is unfavorable for that people use, and need to improve existing PVC waste pipe.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides the noise cancelling type PVC that a kind of intensity is high, drainage noise is little drain structure.

The utility model for the technological scheme that reaches above-mentioned technical purpose and adopt is: a kind of noise cancelling type PVC drain structure, it comprises PVC drain pipe body, on the inwall of described PVC drain pipe body, be evenly provided with and can cut apart the guiding fin that guides current, the inwall of the PVC drain pipe body between described guiding fin is provided with intensive projection and pit.

The cross section of described guiding fin is triangle, and the height of described guiding fin is 5-15mm.

The quantity of described guiding fin is more than six.

The beneficial effects of the utility model are: adopt said structure, on the inwall of PVC drain pipe body, arrange to cut apart and guide the guiding fin of current and intensive projection and pit, guiding fin can be cut apart and lead the water body in waste pipe in flow process, utilize the energy of guiding fin, projection and pit absorption water on inwall, reduce the speed that water body flow clashes into waste pipe, thereby reduce drainage noise.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein:

Fig. 1 is the structural representation of the utility model noise cancelling type PVC drain structure.

Embodiment

By describing technology contents of the present utility model, structure characteristics in detail, being realized object and effect, below in conjunction with mode of execution and coordinate accompanying drawing to be explained in detail.

Refer to shown in Fig. 1, the utility model noise cancelling type PVC drain structure comprises PVC drain pipe body 1, on the inwall of described PVC drain pipe body 1, be evenly provided with and can cut apart the guiding fin 2 that guides current, the inwall of the PVC drain pipe body 1 between described guiding fin 2 is provided with intensive projection 3 and pit 4.

The cross section of described guiding fin 2 is triangle, and the height of described guiding fin 2 is 5-15mm.
