A noise-reducing drainage pipeline structure for indoor use

Abstract

A noise-reduction drainage pipe structure used indoors is installed between a vertical UPVC drainage pipe and a cross drainage pipe, can replace an ordinary tee joint or elbow and comprises a noise-reduction body pipe and accessories. The noise-reduction body pipe is of a concave bowl-shaped structure with a pressure telescopic thorn and composed of a bowl-shaped structure body wall face, an annular wedge-shaped sliding block with a linkage rod, the pressure telescopic thorn and a seal cover plate with an inner seal washer and an outer seal washer. The accessories are a pressure bearing plate and an elastic steel ring. The rigid pressure bearing plate can compress the elastic steel ring to be inclined downwards under the impact of high-speed water flow in the vertical drainage pipe, and the linkage rod is compressed to be linked to the annular wedge-shaped sliding block, so that the annular wedge-shaped sliding block moves downwards along the bowl-shaped structure body wall face, and then the pressure telescopic thorn is extruded to move upwards. The pressure telescopic thorn with a certain slope has the effects of dispersing, flow speed reducing and flow guiding on high-speed water flow, and therefore noise produced by the impact on the pipe wall by the water flow at the joint of the vertical drainage pipe and the cross drainage pipe can be lowered. The noise-reduction drainage pipe structure similar to the tee joint or the elbow to be used at the joint of the vertical drainage pipe and the cross drainage pipe is achieved in the perspective other than improvement in pipe materials and the pipe wall structure; the structure is simple, the effect is obvious, installation and actual application are facilitated, and technical popularization prospect is achieved.

Description

technical field [0001] The invention relates to a noise reduction drainage pipe structure for indoor use, namely a concave bowl-shaped structure pipe part with pressure telescopic thorns, which is installed at the junction of an indoor UPVC drainage riser and a horizontal pipe to buffer the drainage riser. The impact of the middle water flow on the wall of the horizontal pipe reduces noise and belongs to the technical field of drainage engineering. Background technique [0002] UPVC drainage pipes have replaced traditional cast iron drainage pipes with the advantages of smooth inner wall, good drainage performance, light weight and practicality and easy installation, and are widely used in building interiors. However, with the improvement of people's requirements for the living environment, the noise problem brought by UPVC drainage pipes has become a problem that needs to be considered and solved in modern buildings and home life. [0003] The noise generated by the draina...
