Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a drainage pipe capable of reducing noise and keeping quiet. Background Art

[0002] At present, polyvinyl chloride pipes are mostly used in drainage pipes in outdoor and indoor engineering projects, but they make a lot of noise during drainage. In order to overcome the influence of noise, core foam pipes, inner spiral pipes, etc. have been developed successively to reduce the noise during drainage. Although these pipes have a certain quiet effect, people have higher requirements for silent drainage pipes.

[0003] For example, announcement number CN205101702U discloses a new type of internal spiral silent drainage pipe, the inner wall of the pipe is provided with a circle of arc-shaped internal spiral ribs, and the number of internal spiral ribs is 8, 10 or 12. The utility model has the following advantages over the prior art: arc-shaped internal spiral ribs are provided inside the pipe, and the number of internal spiral ribs of the pipe can be selected according to the actual drainage volume, which not only has a good noise reduction effect, but also significantly improves the ring stiffness of the pipe. Its ring stiffness is 1.5 times that of the triangular internal spiral rib pipe, which can reach more than 12KN / m2, ensuring the roundness of the pipe; the inner wall of the pipe is smooth, without burrs or sharp corners, and it is not easy to produce wall hanging phenomenon, so as to ensure smooth drainage of the pipe; the pipe body is formed by nesting the inner pipe and the outer pipe, and the hollow cavity between the inner pipe and the outer pipe can effectively soundproof and has a better silent effect; the drainage joint is connected to the main water pipe through a conical surface and a stepped surface, and the connection structure is firm and reliable, with good sealing performance to avoid water seepage;

[0004] The drainage pipe material in this patent has a more soundproof structure to achieve noise reduction and silencing. However, in high-rise drainage, water flows inside the pipe, which not only collides with the pipe wall and generates noise, but also the internal space of the pipe is limited. When the water flow is large, a water seal will be formed inside the pipe, which will not only cause poor water flow, but also easily generate water noise. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a noise-reducing and silent drainage pipe, which solves the problem that the internal space of the pipe body is limited. When the water flow is large, a water seal will be formed inside the pipe body, which will not only cause poor water flow, but also easily generate water flow noise.
