Helical single-blade cyclone for building drainage
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.
