Abstract

The invention discloses a special swirl assembly for building drainage, which comprises a first water inlet pipe and a second water inlet pipe which is connected to the side wall of the first water inlet pipe and communicated inside. The inner edge of the water inlet pipe is tangent; the connection between the second water inlet pipe and the first water inlet pipe is an enlarged pipe wall cavity. The special swirl assembly of the present invention, when the sewage enters the first water inlet pipe along the second water inlet pipe, the arrangement of the pipe wall cavity can increase the radius of curvature of the swirling flow of the sewage adhered to the wall. When the sewage discharge is large, it can effectively reduce the sewage discharge rate, ensure that the sewage can swirl against the wall, avoid the formation of water plugs, and reduce the generation of drainage noise.

Description

technical field

[0001] The invention relates to the field of building drainage, in particular to a special swirl assembly for building drainage. Background technique

[0002] With the development of technology, the single standpipe has become one of the important pipe fittings of the sewage discharge system in the construction area. Its main advantages are large pipeline flow, convenient installation and use, and less space occupation. However, the internal flow state of the single standpipe currently on the market is chaotic. The specific performance is that when a large amount of sewage enters the vertical standpipe along the horizontal branch pipe, due to the small curvature radius of the pipe, the sewage will directly flow from the vertical standpipe. The middle part of the drain is discharged, not only the drainage noise is loud, but also it is easy to cause water plugging. Contents of the invention

[0003] In order to overcome the above-mentioned defects in the pri...
