Special rotational flow assembly for building drainage

Abstract

The invention disclosed a special rotational flow assembly for building drainage. The special rotational flow assembly comprises a first water inlet pipe and a second water inlet pipe, wherein the second water inlet pipe is connected with the side wall of the first water inlet pipe and communicates with the interior of the first water inlet pipe, the inner edge of the second water inlet pipe is tangent to the inner edge of the first water inlet pipe, and the communication part between the second water inlet pipe and the first water inlet pipe is provided with a pipe wall cavity with an expanded volume. According to the special rotational flow assembly, when sewage enters the first water inlet pipe along the second water inlet pipe, the curvature radius of wall-attached rotational flow of the sewage can be increased through the arrangement of the pipe wall cavity; and when the sewage discharge capacity is large, the sewage discharge rate can be effectively reduced, the wall-attached rotational flow of the sewage can be ensured, formation of water blockage is avoided, and meanwhile generation of water discharge noise is reduced.

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...
