Abstract

The utility model discloses a noise reduction drain pipe with a PP framework, which comprises an inner pipe, a sound absorption cotton layer, a PP framework layer and an outer sleeve from inside to outside; the PP framework layer is of a net structure with meshes made of a PP material; the inner pipe is an integrated structure formed by alternately connecting straight pipes and bent pipes; the cross section of the elbow is formed by splicing two arcs. The utility model discloses a take the drain pipe of making an uproar that falls of PP skeleton, the inner tube is designed to be formed by straight tube and return bend alternate connection to and the design on the cotton layer of sound is inhaled in the outside, can effectively reduce the noise that discharge among the drainage pipe strikes the production. The PP framework layer can enhance the overall strength of the pipeline, effectively protect the inner pipe and prolong the service life of the pipeline.

Description

Noise reduction drain pipe with PP framework

Technical Field

The utility model belongs to the technical field of drainage pipe, specifically relate to a take PP skeleton to fall drain pipe of making an uproar.

Background

At present, the drainage pipe is widely applied in daily life, and particularly for high-rise residences, the drainage pipe is more indispensable. However, the current drain pipe has the following problems: noise and durability issues. Particularly, for some high-rise residences, the noise caused by impact of water flow in the drainage pipe and air pressure is particularly large, the living environment of residents is damaged, and the rest, life, work and the like of the residents are seriously influenced. However, the durability of the drain pipes, especially for interior decoration, is very troublesome if they are damaged and replaced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems, the utility model provides a take PP skeleton to fall the drain pipe of making an uproar, can reduce the noise that discharge among the drainage pipe produced by impact, can promote the life of pipeline again.

The utility model discloses a realize through following technical scheme:

take the drain pipe of making an uproar that falls of PP skeleton, its characterized in that: comprises an inner pipe, a sound-absorbing cotton layer, a PP framework layer and an outer sleeve from inside to outside; the PP framework layer is of a net structure with meshes made of a PP material; the inner pipe is an integrated structure formed by alternately connecting straight pipes and bent pipes; the cross section of the elbow is formed by splicing two arcs.

Furthermore, one side of the sound-absorbing cotton layer is embedded into meshes of the PP framework layer, and the other side of the sound-absorbing cotton layer is tightly attached to the outer surface of the inner pipe.

Further, the circular arc of the bent pipe on the cross section is tangent to the joint of the straight pipe.

The utility model has the advantages that: the utility model discloses a take the drain pipe of making an uproar that falls of PP skeleton, the inner tube is designed to be formed by straight tube and return bend alternate connection to and the design on the cotton layer of sound is inhaled in the outside, can effectively reduce the noise that discharge among the drainage pipe strikes the production. The PP framework layer can enhance the overall strength of the pipeline, effectively protect the inner pipe and prolong the service life of the pipeline.

Drawings

Fig. 1 is a schematic sectional view of the present invention.

In the figure, 1, an inner pipe, 2, an outer sleeve, 3, a PP framework layer, 4, a sound absorption cotton layer, 5, a straight pipe, 6 and a bent pipe.

Detailed Description

The invention will be further described with reference to the following specific examples and the accompanying drawings.

As shown in fig. 1, the noise reduction drain pipe with the PP skeleton comprises an inner pipe 1, a sound absorption cotton layer 4, a PP skeleton layer 3 and an outer sleeve 2 from inside to outside; the PP framework layer 3 is a net-shaped structure with meshes and made of a PP material; the inner pipe 1 is an integrated structure formed by alternately connecting a straight pipe 5 and a bent pipe 6; the section of the elbow 6 is formed by splicing two arcs. One side of the sound-absorbing cotton layer 4 is embedded into the mesh of the PP framework layer 3, and the other side is tightly attached to the outer surface of the inner pipe 1. The arc of the bent pipe 6 on the cross section is tangent to the joint of the straight pipe 5.

The arrow in figure 1 shows the direction of water flow in the inner pipe 1, and the water flow touches the bent pipe 6 to continuously turn back, so that the noise caused by large water flow drop because all the normal water pipes are straight pipes 5 is avoided. The impact of water flow on the pipeline is also reduced, the inner pipe 1 is protected, and the sound absorption cotton layer 4 further reduces the noise. The PP framework layer 3 is designed to enhance the overall strength of the pipeline, effectively protect the inner pipe and prolong the service life of the pipeline.

The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and those skilled in the art should be equivalent replacement modes without departing from the spirit and principles of the present invention.
