Vent drain System
In sanitary facility design, the vent pipe is a hidden player in the drainage system, helping ensure the smooth flow of water.
It's a key component that maintains trap seals and prevents the backflow of odors, gases, and various viruses.
1. Basic principles and roles of the vent system
■ Core functions of the ventilation system
1. Negative pressure relief → Prevent trap seal from being sucked in
2. Relieve pressure → Prevent sealing and destruction
3. Prevents indoor backflow of foul odors and sewage gases
4. Stabilize drainage flow and reduce noise
5. Ensuring air flow in the drain pipe (air supply)
In other words, the ventilation pipe is a key facility that maintains the sanitary environment of a building by maintaining the drainage and ventilation pressure balance.
