Abstract

The invention discloses a low-noise drain pipe which is formed by connecting a first pipe body, a second pipe body, ..., and an n-th pipe body coaxially from inside to outside in a sleeved manner. The inner surface of the first pipe body is provide with multiple spiral grooves which extend along the axial line of the first pipe body; the spiral grooves extend in parallel and mutually wound; the outer surface of the m-th pipe body is a fluctuated curve surface, and the inner surface of the m+1-th pipe body is a fluctuated curve surface which matches with the outer surface of the m-th pipe body; the inner surfaces and the outer surfaces of the second pipe body, ..., and the n-1-th pipe body are waveform curve surfaces with different waveforms; the outer surface of the n-th pipe body is a smooth curve surface; m and n are natural numbers, and m is greater than 1 but less than n; the first pipe body, the second pipe body, ..., and the n-th pipe body are unequal in density. The low-noise drain pipe disclosed by the invention realizes structure improvement of the drain pipe, and achieves good sound attenuation performances and a good sound-isolating effect.

Description

A kind of low noise drain pipe

Technical field

The present invention relates to body equipment technology field, more particularly, to a kind of low noise drain pipe.

Background technology

With the continuous improvement of living standards of the people, everybody requirement to building human settlement also more and more higher it is desirable to obtain Obtain quiet comfortable living space.Current ordinary draining pipe is not good due to soundproof effect, when leading to resident's evening water, current Produce the sleep of noise jamming surrounding user.In prior art, for the improvement of drain pipe noise reduction aspect, focus primarily upon draining The exploitation of pipe material therefor, leads to obtain preferable soundproof effect, and the material cost of drain pipe is higher, needs to improve.

Content of the invention

In order to solve technical problem present in background technology, the present invention proposes a kind of low noise drain pipe it is achieved that right The improvement of drain structure, it has good performance muffler, and soundproof effect is good.

A kind of low noise drain pipe proposed by the present invention, from inside to outside, by the first body, the second body ... the n-th body is successively Coaxially it is socketed to form, the inner surface of the first body is to have a plurality of helicla flute extending along first pipe body axis, above-mentioned a plurality of spiral shell Spin slot extends in parallel mutual winding, and the outer surface of m body is that the inner surface of fluctuating curved surface and m+1 body is and m body The fluctuating curved surface that matches of outer surface, the second body ..., the inner surface of the (n-1)th body and outer surface be that there is different wave Wave curved surface, the outer surface of the n-th body is smooth surface, and wherein, m and n is natural number, and 1 ＜ m ＜ n, the first body, Second body ... the density of the n-th body is not mutually equal.

Preferably, on the first inner surface of tube body, spiral fluted track is circular helix.

Preferably, on the first inner surface of tube body, spiral fluted quantity is 3-5 bar.

Preferably, the numerical value of n is 6-10.

Preferably, the first body, the second body ... the n-th body adopt pvc material make.

Preferably, the first body, the second body ... the n-th body forms coaxial socket by multi-layer co-extruded mode.

In above-mentioned low noise drain pipe, using the frame mode of multilamellar body combination socket formation, in inner side body Surface setting helicla flute is so that when current move in body, in eddy flow state, can reduce the ripple in inner-walls of duct for the current Dynamic, form relatively stable moisture film eddy flow, reduce the noise that current produce；Meanwhile, the body being made using different densities material Between mating surface adopt wave curved surface so that sound in pipe to pipe during propagation, direction and speed change, Meanwhile, the mating surface between different bodys has different waveforms, so that the reflection path during sound transmission More complicated, enhance attenuation degree in communication process for the sound；Therefore, by the improvement of drain structure so that row The wave volume producing during water movement in water pipe is less, and the decay during sound transmission is faster, so that draining Pipe has good performance muffler, and soundproof effect is good.

Brief description

Fig. 1 is a kind of structural representation of low noise drain pipe proposed by the present invention.

Specific embodiment

As shown in figure 1, Fig. 1 is a kind of structural representation of low noise drain pipe proposed by the present invention.

With reference to Fig. 1, in one embodiment, a kind of low noise drain pipe proposed by the present invention, from inside to outside, by the first body 1st, the second body 2 ... the n-th body n is sequentially coaxially socketed to form, the first body 1, the second body 2 ... the coaxial sleeve of the n-th body n Connect and can be realized by multi-layer co-extruded mode；The outer surface of m body m is that the inner surface of fluctuating curved surface and m+1 body m+1 is The fluctuating curved surface matching with the outer surface of m body m, the second body 2 ..., the inner surface of the (n-1)th body and outer surface be tool There is the wave curved surface of different wave, the outer surface of the n-th body n is smooth surface, and wherein, m and n is natural number, and 1 ＜ m ＜ N, due to the mating surface between body adopt wave curved surface so that sound in pipe to pipe during propagation, direction and speed Degree changes, and meanwhile, the mating surface between different bodys has different waveforms, so that during sound transmission Reflection path more complicated, enhance attenuation degree in communication process for the sound, and, when different bodys adopt density mutual When unequal pvc material makes and body quantity is 6-10, the noise reduction and Financial cost of drain pipe is all more satisfactory；First The inner surface of body 1 is to have a plurality of helicla flute extending along the first body 1 axis, and above-mentioned a plurality of helicla flute extends in parallel mutually It is wound around, by the frame mode being formed using the combination socket of multilamellar body, in the inner surface setting helicla flute of inner side body, make Current when move in body, in eddy flow state, the fluctuation in inner-walls of duct for the current, the relatively stable water of formation can be reduced Film eddy flow, reduces the noise that current produce, in order to realize good effect, can control spiral fluted quantity in 3-5 bar, and Spiral fluted Trajectory Design is circular helix；Therefore, by the improvement of drain structure so that draining in-pipe flow fortune The wave volume producing during dynamic is less, and the decay during sound transmission is faster so that drain pipe have good Performance muffler, soundproof effect is good.

The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
