The Laoshan brand ultra quiet spiral single riser drainage system is a new energy-saving and environmentally friendly building drainage system with international advanced level. The emergence of this system has solved the problem of high noise and low drainage capacity in existing building drainage systems. Based on the research on the mechanism of noise generation and the situation of drainage system, our company's ultra quiet spiral single riser drainage system has the following advantages:

Silencing and noise reduction

Due to the unique structure of the ultra quiet spiral single riser drainage system, sewage adheres to the inner wall of the pipeline and forms a spiral like descent, avoiding collisions between water and air, water and pipe walls, reducing pipeline vibration, and significantly reducing the noise of the drainage system. According to national authoritative department testing, building drainage systems with noise indicators less than 45 decibels have significantly lower noise levels than other building drainage systems, ensuring people's physical and mental health and effectively improving the comfort of living and office environments.

Super strong drainage capacity

The current drainage system has chaotic flow patterns and large pressure fluctuations in the vertical pipes. The problem of large water flow at the confluence of the horizontal branch pipes and water blockage at the bottom of the vertical pipes cannot be solved, resulting in pressure imbalance in the pipes, causing negative pressure suction in the upstream pipes and positive pressure splashing in the downstream pipes, seriously affecting the drainage capacity. The ultra quiet spiral single riser drainage system forms a smooth air column in the center of the riser, effectively ensuring pressure balance inside the pipeline and greatly improving the drainage capacity of the system.

green and environmentally friendly

Due to the large instantaneous pressure changes in the existing drainage system, the water seal is damaged, causing harmful gases in the pipeline to flow into the room, posing a threat to people's health.

energy conservation and consumption reduction

According to the GB/T50015-2003 "Code for Design of Building Water Supply and Drainage", ventilation pipes should be installed on floors 10 and above in the existing drainage system.
