Abstract
The utility model discloses it is a kind of can noise-reduction drainpipe, including inner tube（1）, in inner tube（1）Outside is provided with noise reduction layer, and protection pipe is provided with outside noise reduction layer（2）, the noise reduction layer includes porous sound absorption cotton（3）With centrifugation plexiglas cotton layer（4）, porous sound absorption cotton（3）It is wrapped in inner tube（1）Outer wall, centrifugation plexiglas cotton layer（4）It is wrapped in porous sound absorption cotton（3）Outer wall, the utility model have sound absorption function, and on the one hand current spirally can be drained, and reduce the noise that directly impact produces, on the other hand noise caused by draining can be adsorbed, so as to ensure that indoor environment is comfortable.
Description
Technical field
The utility model is related to a kind of drainpipe, especially can noise-reduction drainpipe.
Background technology
In order to facilitate the daily life of resident, skyscraper can all set drainage pipeline, but general drainpipe is being arranged
Noise is bigger during water, particularly plastic drain-pipe, and since inner wall is excessively thin, fluid resistance is small, and flow velocity is fast, and strike note is big, therefore
Larger noise, extreme influence resident's living environment can be produced in bath.
Utility model content
The purpose of this utility model is, in view of the above shortcomings of the prior art, there is provided it is a kind of can noise-reduction drainpipe,
The noise when drainpipe can be by draining is adsorbed, sound insulation, so as to ensure that indoor living environment is comfortable.
To reach above-mentioned technique effect, technical solution is as follows used by the utility model：
The utility model can noise-reduction drainpipe, including inner tube is provided with noise reduction layer, in noise reduction layer outside inner tube
Outside is provided with protection pipe, and the noise reduction layer includes porous sound absorption cotton and centrifugation plexiglas cotton layer, and porous sound absorption cotton is wrapped in
Outer wall of inner tube, centrifugation plexiglas cotton layer are wrapped in porous sound absorption cotton outer wall,
As the preferred solution of the utility model, the porous sound absorption cotton is wave crest acoustical cotton or egg acoustical cotton.
As the preferred solution of the utility model, the wave crest acoustical cotton and egg acoustical cotton are Polyester Fibers.
As the preferred solution of the utility model, semi-circular recesses are evenly equipped with the inner surface of inner tube.
As the preferred solution of the utility model, the inner surface of inner tube is provided with spiral bar.
As the preferred solution of the utility model, the cross section of the spiral bar is triangle.
As the preferred solution of the utility model, it is provided with along what the spiral bar hand of spiral was set and leads in spiral bar upper surface
Chute.
The beneficial effects of the utility model are：The utility model has sound absorption function, on the one hand current can be carried out spiral
Formula drains, and reduces the noise that directly impact produces, on the other hand noise caused by draining can be adsorbed, so as to ensure room
Interior amenity.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in drawings, the utility model can noise-reduction drainpipe, including inner tube 1 is provided with outside inner tube 1 and disappears
Sound-absorbing layer, is provided with protection pipe 2 outside noise reduction layer.Protection pipe is used to protect drainpipe internal structure, prevents noise reduction layer
It is insecure to be damaged.
Noise reduction layer has good noise elimination effect, and the noise reduction layer includes porous sound absorption cotton 3 and centrifugation plexiglas cotton layer
4, porous sound absorption cotton 3 is wrapped in 1 outer wall of inner tube, and centrifugation plexiglas cotton layer 4 is wrapped in 3 outer wall of porous sound absorption cotton.
Its material internal of porous sound absorption cotton 3 has a large amount of small holes communicated, and sound wave enters hole and material friction, weakens
Sound wave pulse.It is fluffy staggeredly to centrifuge plexiglas cotton internal fiber, there are a large amount of small holes, is that typical porosity is inhaled
Sound material, has good sound absorption characteristics, can largely absorb the acoustic energy of draining, prevent room noise.
Preferably, the porous sound absorption cotton 3 is wave crest acoustical cotton or egg acoustical cotton.The ripple of wave crest acoustical cotton shape uniqueness
Peak is very strong to the absorbability of high frequency, while also has the effect of good buffering vibration, drainpipe is protected, also with fire-retardant
Characteristic, improves the water resistance of drainpipe.Further, the wave crest acoustical cotton and egg acoustical cotton are Polyester Fibers.
Sound deadening during to play draining, spiral bar 6 is provided with the inner surface of inner tube 1.Spiral bar can to draining into
Row drainage, is changed to screw type rotary draining, so as to there is relatively effect to reduce drainage noise by original directly impact.
The cross section of the spiral bar 6 is triangle.
To improve drainage effect, the diversion trench 7 set along the spiral bar hand of spiral is provided with 6 upper surface of spiral bar.
To further improve the noise reduction of drainpipe, semi-circular recesses 5 are evenly equipped with the inner surface of inner tube 1.It is semicircle
On the one hand groove has an acoustically effective, on the other hand also have the function that necessarily prevent current from directly impacting, noise reduction can be optimized
Effect.
