Anti Siphon Pressure Reducing Valve
Anti Siphon Pressure Reducing Valve FAQ (Simplified)
- What is the core principle of the Anti Siphon Pressure Reducing Valve?
A: It reduces inlet pressure to a stable outlet pressure by dynamically adjusting flow resistance (e.g., narrowing the passage area). Excess energy (e.g., 800kPa input → 100-200kPa output) is dissipated internally (via springs, channels, etc.), maintaining pressure balance using fluid force and spring regulation.
- How does it prevent siphon/backflow?
A: It integrates two functions:
- Pressure Reduction: Regulates high inlet pressure to a safe outlet range.
- Anti-Siphon Check Valve: Features a one-way flow design with >2kPa activation pressure (per YY0585.4). If downstream pressure drops (e.g., siphon risk), the valve closes tightly to block reverse flow, preventing contamination (e.g., dirty water from plumbing back into mains).
- What are its key advantages?
A:
• Cost & Space Efficiency: Combines + into one unit.
• Hygiene Protection: Stops wastewater from re-entering clean water pipes.
• Fail-Safe Design: Normally open (ensures flow), but closes instantly if pressure reverses.
• Standards-Compliant: Meets YY0585.4 for medical-grade reliability.
- Where is it commonly used?
A:
• Plumbing systems (toilet tanks, faucets) to prevent backflow pollution.
• Medical devices (e.g., IV lines) requiring pressure control + contamination prevention.
• Irrigation networks with risk of siphon due to fluctuating pressures.
