排氣閥(Air release velve)
Working of Air Release Valves
Automatic air release valves are located at the highest points of the pipeline or other systems where air naturally collects. The air bubbles enter the air relief valve and displace the inside liquid. Thus the liquid level is lowered. When the liquid level drops to such an extent that it no longer buoys the float, the float drops causing the valve to open which vents the accumulated air into the atmosphere.
Once the air is released, the liquid re-enters the valve, lifting the float until the seat presses against the orifice, and closing the valve. This cycle continues automatically and maintains an air-free system.
