Drainage pipeline structure for indoor noise reduction and noise reduction method thereof

Abstract

The invention discloses a drainage pipeline structure for indoor noise reduction and a noise reduction method thereof. The drainage pipeline structure for indoor noise reduction comprises a noise reduction main body pipe, a first magnetic ring and a shunting arc plate are fixedly installed in the noise reduction main body pipe, and a second magnetic ring and an annular downward pressing plate areslidably installed in the noise reduction main body pipe. The noise reduction method comprises the following steps that S1, after making contact with the shunting arc plate in the downward flowing process of water flow, the water flow flows downwards from the two sides of the shunting arc plate. The drainage pipeline structure for indoor noise reduction and the noise reduction method thereof havethe advantages that the first magnetic ring and the second magnetic ring are matched to achieve automatic upward movement of the annular downward pressing plate when stress is reduced or disappears; the first magnetic ring and the second magnetic ring are made of samarium-cobalt materials and can be normally used in water for a long time; when the annular downward pressing plate is impacted by water flow to move downwards, a speed reduction frame plate can be driven to rotate, the surface inclination of the speed reduction frame plate is reduced when the speed reduction frame plate rotates, and therefore the impact effect generated when the water flow makes contact with the speed reduction frame plate is reduced; and the water flow can make contact with the bottom wall of the noise reduction body pipe at a lower speed, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of drainage pipes, in particular to an indoor noise reduction drainage pipe structure and a noise reduction method thereof. Background technique [0002] Common sound-reducing tubes currently on the market include inner spiral tubes, double-wall vacuum tubes, core-layer foam tubes, sandwich tubes, etc. Although this type of sound-falling tube has a certain sound-reducing effect, it is not necessary in the specific use process. Such pipes still have a lot of noise, and the sound reduction effect is not outstanding. [0003] The authorized invention patent with the patent number CN105485464B discloses a drainage pipe for indoor noise reduction, which is installed between the UPVC drainage standpipe and the horizontal drainage pipe, and can replace ordinary tees or elbows, including noise reduction main pipe fittings and accessories. The noise-reducing main pipe fitting is a concave bowl-shaped structure with ...

AI Technical Summary

Problems solved by technology

[0004] But this noise-reducing drainage pipe has the following problems: 1. The elastic steel coil is prone to rust when in contact with water for a long time, which affects normal use; 2. figure 1 It can be clearly seen that when the ring wedge slider moves down, it cannot produce an upward extrusion force on the pressure telescopic thorn
