Working Principle of Siphonic Drainage Bottle-Neck Tee

PE Butt Fusion Siphon Drainage Tee
 
Its working principle is based on flow control and negative pressure stabilization:
  1. Its special necked-down structure reduces the pipe cross-section locally, which helps speed up the water flowandsuppress air entrainment into the pipeline.PE Butt Fusion Siphon Drainage Tee
  2. By limiting air intake and stabilizing flow velocity, it helps the system quickly form and maintain full-bore flow and stable negative pressure.PE Butt Fusion Siphon Drainage TeePPE Butt Fusion Siphon Drainage TeeE Butt Fusion Siphon Drainage Tee
  3. This eliminates air locks and turbulence, allowing the siphonic effect to work continuously and efficiently, so rainwater is discharged rapidly and quietly.PE Butt Fusion Siphon Drainage Tee

Function

Thesiphon drainage bottle-neck tee is a key pipe fitting used in siphonic roof drainage systems.PE Butt Fusion Siphon Drainage Tee
  • It connects the horizontal branch pipe and vertical downpipe while maintaining stable negative pressure for efficient siphonic flow.
  • Its special neck‑shaped structure helps restrict air intake, stabilize water flow, and improve drainage efficiency.
  • It reduces turbulence and noise, prevents air locks, and ensures the system operates at full bore.
