A drainage pipe structure for indoor noise reduction and noise reduction method thereof

Abstract

The invention discloses an indoor noise-reducing drainage pipe structure and a noise-reducing method thereof. A second magnetic ring and an annular lower pressure plate are installed in the inner slide. The method includes the following steps: S1, after the water flow contacts the diverter arc plate in the process of flowing downward, it will divert and flow down from both sides of the diverter arc plate. The advantages are: the cooperation of the magnetic ring 1 and the magnetic ring 2 can realize the automatic upward movement of the annular lower pressure plate when the force is reduced or disappears, and the magnetic ring 1 and the magnetic ring 2 are made of samarium cobalt material to ensure that the two can be normal for a long time It can be used in water; when the annular lower pressure plate moves down under the impact of water flow, it can drive the speed-reducing frame to rotate. The water flow can be brought into contact with the bottom wall of the noise-reducing main pipe fitting at a more gentle speed, thereby reducing noise.

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
