1, due to noise silencing and noise reduction: swirling special special structure of single riser drainage system sewage pipe wall attached to form a spiral fall, to avoid the collision between the water and the air, water and pipe, reducing pipe vibration and noise is greatly reduced the drainage system, the noise index of less than 45 dB (currently the lowest) the building drainage system, the noise is much lower than the other building drainage system, to ensure their physical and mental health, improve the working environment of comfort and rest.
2, the drainage capacity of the existing drainage system: Super vertical pipe flow chaos, large pressure fluctuation, horizontal branch flow in vertical tubes is not water tongue and the bottom of the vertical pipe of the water plug to solve the problem of confluence, resulting in pipeline pressure imbalance, the formation of negative pressure suction pipe upstream, downstream of the barotropic splash phenomenon, serious effect of drainage capacity. The swirling noise of the special single riser drainage system in the vertical tube formed in the center of the air column flow, effectively guarantee the balance of pressure in the pipeline, and can greatly improve the ability of drainage system.
3, environmental protection: the existing drainage system due to instantaneous pressure changes, resulting in water damage, caused by the harmful gas in the pipeline into the interior, bring harm to people's physical and mental health.2003 SARS years after the outbreak of the Hongkong Amoy Gardens incident, is a typical example. Due to the unique shape of the cyclone drainage system, the system has a very good ventilation ability, and the pressure fluctuation in the pipe is very small, which will not cause the water seal damage.
4, energy conservation and consumption: the existing drainage system according to the GB50015-2003 "building drainage design standards" provisions in the 10 layer and above to set up ventilation tube, swirling noise singlestack systems due to excellent drainage conditions, without the need for additional ventilation pipe, which saves materials, and improve the utilization rate of space played a good the effect of energy saving.
