Noise-reduction energy-dissipation PVC pipe fitting for high-rise building drainage system

Abstract

The invention provides a noise-reduction energy-dissipation PVC pipe fitting for a high-rise building drainage system. The noise-reduction energy-dissipation PVC pipe fitting for a high-rise buildingdrainage system comprises a hollow main body with the top end open. A sealing cover is installed at the top end of the main body in a matched manner. A water inlet is formed in the left side wall of the main body. A water outlet is formed in the right side wall of the main body. A waterflow distribution and conflux plate with the rhombic cross section is arranged inside the main body in the mannerof being attached to the bottom surface of the main body and the bottom surface of the sealing cover. The waterflow distribution and conflux plate keep distance from the periphery of the inner wall of the main body. One of the two opposite angles of the waterflow distribution and conflux plate faces the water inlet, and the other one faces the water outlet. With the noise-reduction energy-dissipation PVC pipe fitting for a high-rise building drainage system, the defects that a PVC pipe is high in noise in drainage, and low in pressure bearing of drainage can be effectively overcome. Additionally, the noise-reduction energy-dissipation PVC pipe fitting for a high-rise building drainage system is convenient and quick to install, easy to operate, smaller in occupied space, and more importantly, more safe and reliable.

Description

technical field [0001] The invention relates to the field of building drainage, and more specifically relates to a noise-reducing and energy-dissipating PVC pipe fitting for a high-rise building drainage system. Background technique [0002] With the increase of high-rise and ultra-high-rise buildings, the requirements for building materials are also getting higher and higher. The disadvantages of traditional cast iron drainage pipes, such as short life and easy aging, are becoming less and less acceptable. Compared with cast iron pipes, the advantages of polyvinyl chloride (PVC) plastic pipes such as economic benefits and long life are becoming more and more prominent. [0003] However, PVC pipes also have their own defects: ①Drainage noise is large: due to the smooth inner wall of the U-PVC drainage pipe, the water flow is not easy to form a water film and flow along the pipe wall, and hits the pipe wall in a chaotic state in the pipe; in addition, the U-PVC drainage pipe ...
