Problems solved by technology

Due to the poor sound insulation effect of the current ordinary drainage pipes, when residents use water at night, the water flow produces noise and disturbs the sleep of surrounding users
In the prior art, the improvement of drainage pipe noise reduction mainly focuses on the development of the materials used in the drainage pipe, resulting in the high material cost of the drainage pipe in order to obtain the ideal sound insulation effect, which needs to be improved

Embodiment Construction

[0012] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a low-noise drainage pipe proposed by the present invention.

[0013] refer to figure 1 , in one embodiment, a low-noise drainage pipe proposed by the present invention is formed by coaxially socketing the first pipe body 1, the second pipe body 2, ... the nth pipe body n in sequence from the inside to the outside, The coaxial socket connection of the first pipe body 1, the second pipe body 2, ... the nth pipe body n can be realized by multi-layer co-extrusion; the outer surface of the mth pipe body m is an undulating surface and the m+1th pipe body The inner surface of m+1 is an undulating curved surface matching the outer surface of the mth pipe body m, the inner surface and outer surface of the second pipe body 2, ..., the n-1th pipe body are wavy curved surfaces with different waveforms, and The outer surface of n pipe body n is a smooth curved surface, where m and n are both natural numb...

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

technical field [0001] The invention relates to the technical field of pipe equipment, in particular to a low-noise drainage pipe. Background technique [0002] With the continuous improvement of people's living standards, everyone has higher and higher requirements for the architectural living environment, hoping to obtain a quiet and comfortable living space. Due to the poor sound insulation effect of the current ordinary drainage pipes, when residents use water at night, the water flow produces noise and disturbs the sleep of surrounding users. In the prior art, the improvement of the drainage pipe noise reduction mainly focuses on the development of the material used for the drainage pipe, resulting in the high material cost of the drainage pipe in order to obtain an ideal sound insulation effect, and needs to be improved. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a low-nois...
