Abstract

The utility model relates to a noise-absorbing plastic pipe, which is characterized in that the pipe wall of the noise-absorbing plastic pipe is a hollow pipe wall. The noise-absorbing plastic pipe has the advantages of simple structure, good noise-absorbing effect, less material consumption and high strength.

Description

The noise elimination plastic tube

The utility model relates to plastic tube, especially a kind of noise elimination plastic tube.

Produce plastics drainage pipeline, the electric wire sleeve pipe that uses at present on the market, its tube wall all is solid, and they are noise very big (particularly drainage pipeline) in use, influence daily life, and this pipe consumptive material is also many, causes cost to increase.

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose a kind of sound insulation function that both had, can falling the noise elimination plastic tube of low material consumption again.

At the foregoing invention purpose, the utility model proposes following technological scheme: a kind of noise elimination plastic tube, its special way are that the tube wall of this plastic tube is hollow tube wall.

In such scheme, the hollow tube wall of described plastic tube preferably adopts the mode that is covered with many emptying apertures in the tube wall to realize.

The utility model has been owing to adopted hollow tube wall, and therefore, the sound that sends when it can absorb current cuts off the sound of current, and after testing, it can reduce about 50% of flowing water noise.

Because it is hollow that tube wall is made, make same wall thickness, same length, same specification, with the tubing of material, can save material 32%.

The utility model has thoroughly solved sewer material in the background technique, electric wire sleeve pipe noise height, and the problem that consumptive material is many has brought convenience for people's life, has reduced cost of production, increases benefit.

Below in conjunction with the accompanying drawing illustrated embodiment, describe the utility model in detail.

Fig. 1 is the utility model plan view.

Fig. 2 is the axial sectional view of Fig. 1.

Plastic tube 1 of the present utility model as shown in Figure 1, it can be pipe, it also can be the steel tubing in different shapes of square tube or other shape, in its tube wall, be covered with vertically many emptying apertures that are parallel to each other 2 are arranged, the shape of this emptying aperture 2 can be circular, it also can be other irregularly-shaped hole, its arrangement also can with the axioversion several angle of plastic tube 1, plastic tube 1 is that extruding forms through mould by extrusion press with the PVC material, and the emptying aperture 2 in the plastic tube tube wall is to reserve one-time formed emptying aperture by mould in the extrusion modling process.

Claims

1, a kind of noise elimination plastic tube, the tube wall that it is characterized in that described plastic tube is hollow tube wall.

2,, it is characterized in that being covered with in the tube wall of described plastic tube many emptying apertures are arranged according to the described noise elimination plastic tube of claim 1.
