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 waste pipe

Technical field

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

Background technique

Along with improving constantly of living standards of the people, everybody is also more and more higher to the requirement of building human settlement, ites is desirable to obtain quiet comfortable living space.Current normal discharge pipe due to soundproof effect not good, when causing resident's water in evening, current produce the sleep of noise jamming surrounding user.In prior art, for the improvement of waste pipe noise reduction aspect, mainly concentrate on the exploitation of waste pipe material therefor, cause obtaining desirable soundproof effect, the cost of material of waste pipe is higher, needs to improve.

Summary of the invention

In order to solve the technical problem existed in background technique, the present invention proposes a kind of low noise waste pipe, achieve the improvement to drain structure, it has good performance muffler, and soundproof effect is good.

A kind of low noise waste pipe that the present invention proposes, from inside to outside, by the first body, second body, n-th body is coaxially socketed to form successively, the internal surface of the first body is have many spiral chutes along the first body Axis Extension, above-mentioned many spiral chutes extend in parallel mutual winding, the outer surface of m body is fluctuating curved surface and the internal surface of m+1 body is the fluctuating curved surface matched with the outer surface of m body, second body, the internal surface of the (n-1)th body and outer surface are the wave curved surface with different wave, the outer surface of the n-th body is smooth surface, wherein, m and n is natural number, and 1 < m < n, first body, second body, the density of the n-th body is unequal mutually.

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 ... n-th body adopts PVC material to make.

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

In above-mentioned low noise waste pipe, adopt the mode of structure that multilayer body combination socket is formed, at the internal surface of inner side body, spiral chute is set, when current are moved in body, in eddy flow state, the fluctuation of current at inner-walls of duct can be reduced, form comparatively stable moisture film eddy flow, reduce the noise that current produce; Simultaneously, fitting surface between the body adopting different densities material to make adopts wave curved surface, in the process that sound is propagated in pipe to pipe, direction and speed change, simultaneously, fitting surface between different body has different waveforms, thus the reflection path in sound transmission process can be made more complicated, enhances the attenuation degree of sound in propagation process; Therefore, by the improvement to drain structure, make the wave volume that produces in water movement process in waste pipe less, and decay in sound transmission process is faster, thus makes waste pipe have good performance muffler, soundproof effect is good.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of low noise waste pipe that the present invention proposes.

Embodiment

As shown in Figure 1, Fig. 1 is the structural representation of a kind of low noise waste pipe that the present invention proposes.

With reference to Fig. 1, in one embodiment, a kind of low noise waste pipe that the present invention proposes, from inside to outside, by the first body 1, second body 2 ... n-th body n is coaxially socketed to form successively, the first body 1, second body 2 ... the coaxial socket of the n-th body n can be realized by multi-layer co-extruded mode, the outer surface of m body m is fluctuating curved surface and the internal surface of m+1 body m+1 is the fluctuating curved surface matched with the outer surface of m body m, second body 2, the internal surface of the (n-1)th body and outer surface are the wave curved surface with different wave, the outer surface of the n-th body n is smooth surface, wherein, m and n is natural number, and 1 < m < n, because the fitting surface between body adopts wave curved surface, in the process that sound is propagated in pipe to pipe, direction and speed change, simultaneously, fitting surface between different body has different waveforms, thus the reflection path in sound transmission process can be made more complicated, enhance the attenuation degree of sound in propagation process, and, when different body adopts the mutual unequal PVC material of density to make and body quantity is 6-10, noise reduction and the financial cost of waste pipe is all more satisfactory, the internal surface of the first body 1 is have many spiral chutes along the first body 1 Axis Extension, above-mentioned many spiral chutes extend in parallel mutual winding, by the mode of structure adopting multilayer body combination socket to be formed, at the internal surface of inner side body, spiral chute is set, when current are moved in body, in eddy flow state, the fluctuation of current at inner-walls of duct can be reduced, form comparatively stable moisture film eddy flow, reduce the noise that current produce, in order to realize good effect, spiral fluted quantity can be controlled at 3-5 bar, and be circular helix by spiral fluted Trajectory Design, therefore, by the improvement to drain structure, make the wave volume that produces in water movement process in waste pipe less, and decay in sound transmission process is faster, thus makes waste pipe have good performance muffler, soundproof effect is good.

The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
