Abstract

The utility model discloses a double-wall spiral hush pipe, and relates to a plastic drain pipe, in particular to a drain pipe which can reduce noise. The double-wall spiral hush pipe aims to overcome the defect that an existing drain pipe is high in noise, and is a drain pipeline which is simple in structure and capable of reducing and insulating the noise. The double-wall spiral hush pipe comprises a pipe body, and is characterized in that the pipeline wall comprises two layers which are connected, the inner wall and the outer wall are alternate with each other and provided with through holes which are evenly arranged, and protruding diversion ribs are evenly arranged along the inner pipe wall. The double-wall spiral hush pipe is mainly applied to a modern construction drainage system.

Description

A kind of double-walled spiral hush pipe

Technical field

The utility model relates to a kind of plastic cement waste pipe, waste pipe that especially can noise reduction.

Background technique

In existing building, the drainage system auxiliary facility that is absolutely necessary, but the noise of drainage system directly affects resident's living environment.Pipeline is the main composition parts of drainage system, and good pipeline can bring assurance for the use safety and stablization of drainage system.Along with the raising of people to quality of life and environmental requirement, improve for the requirement of water system thereupon, the modern also pays close attention to the noise problem of pipeline except requiring water treatment system tube performance safety and stability.Common drainage pipe is mostly simple in structure, erasure effect is poor, and when current being arranged fast through out-of-date, current hit the pipe wall, the extruding air easily produces continuous noise, causes and pollutes people's living environment.

The model utility content

The purpose of this utility model is to overcome above-mentioned technological deficiency, provides a kind of simple in structure, can noise reduction, the drainage pipe of sound insulation.

The utility model is realized purpose by the following technical solutions: a kind of double-walled spiral hush pipe, comprise pipe shaft, and it is characterized in that: tube wall is one-piece double-layer, alternate even row's example has the interval through hole between inside and outside two walls, evenly is provided with the guide rib of projection along inner tubal wall.

Through hole sectional shape in interval between described wall can be circular, oval, rectangle.

Described inwall guide rib and preferred 45 ° of axial angle, sectional shape triangle.

The utility model beneficial effect is:

1, current fall under the inner tube wall guide functions in the shape of a spiral, and under the double action of porous sound insulation on the double-walled, can greatly reduce the noise of pipe-line system, and drainage noise power only is 50% of common tube.　

2, current are obvious attached jet in the soil stack, reduced water velocity, reduce the overflow resistance coefficient, keep center gas up/down perforation in the standpipe, steadily overpressure fluctuates, and has improved the drainability of standpipe, has reduced air displacement, drainability increases approximately 25%-35%, and air displacement reduces approximately 15%-20%.　　

3, owing in the pipe unimpeded air column being arranged, reduced overpressure and pressure surge, improved pipeline and used safety coefficient.4, adopt double-walled helical silencing list standpipe, can remove the two standpipe ventilating modes of H type from, reduce engineering cost and piping lane area.

Among the figure: pipe outer wall 1, interval through hole 2, guide rib 3, inner tube wall 4.

Embodiment

For the clearer statement of technological scheme that the utility model is realized, further set forth the utility model below in conjunction with concrete diagram.

A kind of double-walled spiral hush pipe comprises pipe shaft, it is characterized in that tube wall is that one-piece double-layer is namely managed outer wall 1, inner tube wall 4, and alternate even row's example has interval through hole 2 between inside and outside two walls, evenly is provided with the guide rib 3 of projection along inner tubal wall.

Outside possessing all advantage performances of solid wall pipe, more obvious with soundproof effect, it can reduce the 8-10 decibel than standard solid wall pipe, has really contained the noise that produces in the effluent discharge process, thereby makes living environment more warm, quiet.

Claims

1. a double-walled spiral hush pipe comprises pipe shaft, it is characterized in that: tube wall is one-piece double-layer, and alternate even row's example has the interval through hole between inside and outside two walls, evenly is provided with the guide rib of projection along inner tubal wall.

2. double-walled spiral hush pipe according to claim 1, it is characterized in that: interval through hole sectional shape is circle or ellipse or rectangle between wall.

3. double-walled spiral hush pipe according to claim 1 is characterized in that: the inwall guide rib is 45 ° with axial angle, guide rib sectional shape triangle.
