A Curved Composite Silent Drain Pipe

Abstract

The invention discloses a curved composite silent drainage pipe, which comprises a three-way valve one, two water pipe bodies made of stainless steel are symmetrically arranged at both ends of the three-way valve one, and the inner wall of the water pipe body is fixed with A plurality of water flow damping blocks, the outer wall of the water pipe body is provided with a cavity. The present invention can utilize the provided cavity and the water flow damping block to effectively isolate the sound emitted by the water flow in the water pipe, and at the same time reduce its propagation path inside the water pipe, thereby achieving a very good sound insulation effect. In addition, use the heating device to heat the inside of the water pipe when the temperature is low in winter to prevent it from freezing and cracking to ensure the normal use of the water pipe, and use the injection device and cleaning device to clean the scale on the inner wall of the water pipe. Effectively dissolve and clean, ensure the unimpeded discharge of water inside the water pipe, and improve the operation quality of the building drainage system.

Description

technical field [0001] The invention relates to the field of drainage equipment manufacturing, in particular to a curved composite silent drainage pipe. Background technique [0002] On the floors of urban buildings, there are often thousands of drainage pipes like spider webs, which form a huge drainage pipe network system, which can meet the drainage needs of people's daily work and life in the building. Therefore, a drainage pipe with good quality and reliable performance The drainage pipe is very important for the drainage system of a building. [0003] However, in the current building floors, the drainage pipes used are mostly water pipes made of relatively common PVC materials in the market. In actual use, especially in the process of drainage, considering the current The building floors are relatively high, so when the water flows in the water pipes, there will be a loud sound of water flow. At the same time, due to the lack of a corresponding sound insulation struc...

Problems solved by technology

[0003] However, in the current building floors, the drainage pipes used are mostly water pipes made of relatively common PVC materials in the market. In actual use, especially in the process of drainage, considering the current The building floors are relatively high, so when the water flows in the water pipes, there will be a loud sound of water flow

At the same time, due to the lack of corresponding sound insulation structure, it will affect the normal rest of people in the building, and when the temperature is low in winter, because of the lack of antifreeze protection device, the water pipe is likely to be damaged by freezing and damage

Moreover, after long-term use, a thick layer of scale will be formed on the inner wall of the water pipe, which will hinder the normal flow of water in the water pipe. If it is not cleaned in time, it will cause blockage of the water pipe over time, so it is necessary to design a curved composite silent drain pipe to solve such problems
