Abstract

The invention discloses a helical single-blade cyclone for building drainage. The helical single-blade cyclone for building drainage comprises a tee joint body, wherein the upper interface of a main pipe of the tee joint body is connected with an upper connecting pipe section for connecting an upper stand pipe, the lower interface of the main pipe of the tee joint body is connected with a lower connecting pipe section for connecting a lower stand pipe, a helical guide blade is arranged on the inner wall of the lower connecting pipe section, and an inwards-flanging arc guide edge is arranged on the inner wall of the bottom of the upper connecting pipe section. According to the helical single-blade cyclone for building drainage, good wall-attached flows can be formed during large displacement through the cooperation of the inwards-flanging arc guide edge and the helical guide blade, the phenomenon of hydraulic jumping and the phenomenon that the blade is directly flushed are avoided, good ventilating effect is achieved, pressure fluctuation can be reduced and the water drainage capability is improved; and the single helical guide blade can prevent multi-blade multi-flow convergence, the water flow falling speed is lowered, the noise is lowered, the odor of the toilet is avoided and the drainage capability is improved.

Description

technical field

[0001] The invention relates to the field of building drainage pipes, in particular to a spiral single-blade cyclone for building drainage. Background technique

[0002] The cyclone is a new type of special accessory in the special single-standpipe drainage system. Compared with other special single-standpipe systems, the single-standpipe drainage system using the cyclone has the advantages of large flow and small space occupation. see figure 1 As shown, the upper riser interface of the existing swirler 10 is generally a cylindrical short pipe 11 arranged in the center, and the lower body swirl body 12 of the swirler 10 is provided with a plurality of helical blades 13. The swirler with this structure 10 has the following defects: 1. When used in high-rise and ultra-high-rise buildings, when large-displacement drainage is performed, since the upper riser interface is at the center, the large water flows downward and is colliding with multiple spirals of the ...

Embodiment Construction

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0019] see image 3 and Figure 4 A spiral single-blade cyclone for building drainage is shown, including a three-way body 100, the main pipe upper interface 110 of the three-way body 100 is connected to the upper connecting pipe section 200, and the main pipe lower interface 120 of the three-way body 100 is connected to the lower Pipe sections 300 are connected. In this embodiment, the upper connecting pipe section 200, the lower connecting pipe section 300 and the tee body 100 are detachably connected by buckles, so that it is convenient to replace the upper connecting pipe section 200 and the lower connecting pipe section 300 of different types according to risers of different pipe diameters. Enhance the versatility of the present invention.
