Abstract

The utility model discloses a two spiral muscle silence drain pipes of polypropylene, including the drain pipe body, an organic whole is connected with first spiral muscle on the inner wall of drain pipe body, it inhales the sound cotton to bond on the outer wall of drain pipe body, it has second spiral muscle to inhale the fixed winding in cotton outside of sound, first spiral muscle and second spiral muscle are the spiral and distribute in the axial of drain pipe body. The utility model discloses rational in infrastructure, through first spiral muscle at the internal surface formation bellied line of drain pipe body, this line can carry out water conservancy diversion or drainage to liquid such as water. Inhale the sound cotton through bonding on the outer wall of drain pipe body, sound insulation function that the cotton has through inhaling can effectually reduce the inside fluidic sound of drain pipe body and pass to the outside. Through the fixed winding second spiral muscle in the outside of inhaling the sound cotton, second spiral muscle intensity is high, the fastening nature is good, can effectually fasten the cotton outer surrounding of inhaling the sound.

Description

Polypropylene two-spiral-rib mute water drainage pipe

Technical Field

The utility model relates to the technical field of, especially, relate to a two spiral muscle silence drain pipes of polypropylene.

Background

Along with the improvement of living standard of people, more and more hot water gets into building drainage pipe system, and the chance that drainage pipe contacts hot water of 50 ~ 60 ℃ increases gradually. At present, polyvinyl chloride drainage pipes are mainly used for building drainage, and the heat-resistant temperature of the material is 40 ℃, so that if the heat-resistant temperature exceeds 40 ℃ after long-term heating, the heat aging of the pipe can be caused, and the strength and the service life of the pipe can be reduced. In addition, the polyvinyl chloride drain pipe has high water flow noise and cannot meet the requirements of high-quality life.

The pipeline noise is formed by combining pneumatic sound transmission and fixed sound transmission, when the drainage pipeline is filled with air for drainage, the sound wave transmission by taking air as a medium is realized, and the noise is formed by pipe vibration caused by flowing of water and solid impurities and impact on the pipe wall. Therefore, to reduce the noise in plastic drainage pipes, the plastic pipe should be made of a material that absorbs sound waves and the noise generated by the vibration of the pipe wall.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a two spiral muscle silence drain pipes of polypropylene to solve the problem that above-mentioned background art part provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

two spiral muscle silence drain pipes of polypropylene, including the drain pipe body, an organic whole is connected with first spiral muscle on the inner wall of drain pipe body, it inhales the sound cotton to bond on the outer wall of drain pipe body, the fixed winding in the outside of inhaling the sound cotton has second spiral muscle, first spiral muscle and second spiral muscle are the spiral and distribute in the axial of drain pipe body.

Furthermore, the first spiral rib is made of steel wires.

Further, the outer surface of the steel wire is evenly coated with anti-corrosion paint.

Furthermore, the drain pipe body and the first spiral rib are both made of polypropylene resin.

Further, the cross section of the first spiral rib is semicircular.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a first spiral muscle forms bellied line at the internal surface of drain pipe body, and this line can carry out water conservancy diversion or drainage to liquid such as water.

2. The utility model discloses a bond on the outer wall of drain pipe body and inhale the sound cotton, can effectually reduce the inside fluidic sound of drain pipe body and pass to the outside through inhaling the sound insulation function that the sound cotton has.

3. The utility model discloses a fixed winding second spiral muscle in the cotton outside of sound absorption, second spiral muscle intensity is high, fastening nature is good, can effectually fasten the cotton outer surrounding of sound absorption.

Drawings

Fig. 1 is a schematic structural view of the two spiral rib mute drainpipes made of polypropylene according to the present invention.

In the figure: 1 drain pipe body, 2 first spiral muscle, 3 inhale sound cotton, 4 second spiral muscle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, two spiral muscle silence drain pipes of polypropylene, including drain pipe body 1, an organic whole is connected with first spiral muscle 2 on the inner wall of drain pipe body 1, bonds on the outer wall of drain pipe body 1 and has inhales the sound cotton 3, inhales the fixed winding in the outside of sound cotton 3 and has second spiral muscle 4, and first spiral muscle 2 and second spiral muscle 4 are the spiral and distribute in the axial of drain pipe body 1.

In the above embodiment, the first spiral rib 2 forms a raised texture on the inner surface of the drain pipe body 1, and the texture can guide or drain liquid such as water. Inhale the sound cotton 3 through bonding on the outer wall of drain pipe body 1, can effectually reduce the inside fluidic sound of drain pipe body 1 and pass to the outside through inhaling the sound insulation function that sound cotton 3 had. Through the fixed winding second spiral muscle 4 in the outside of inhaling sound cotton 3, 4 intensity height, the fastening nature of second spiral muscle are good, can effectually fasten the outer surrounding of inhaling sound cotton 3.

Specifically, the first spiral rib 2 is made of a steel wire.

In the above embodiment, the first spiral rib 2 made of the steel wire has high strength and good fastening property.

Specifically, the outer surface of the steel wire is evenly coated with anticorrosive paint.

In the above embodiment, the corrosion of the steel wire can be further reduced by uniformly coating the outer surface of the steel wire with the anti-corrosion paint.

Specifically, the drain pipe body 1 and the first spiral rib 2 are both made of polypropylene resin.

In the above examples, the polypropylene resin has high resistance to hot water, corrosive liquids and mechanical scratches.

Specifically, the cross section of the first spiral rib 2 is semicircular.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
