Audited Supplier DN150 Double Orifices SS316 Automatic Air Vent Valve
Introduction:
QB2 flange double orifice air vent valve When it is necessary to discharge the gas in the pipeline, the valve rod shall be rotated counterclockwise to make the valve rod and the valve rise, so that the air in the pipeline enters the body cavity under the pressure of water and is discharged from the exhaust nozzle. Then the water in the pipeline fills the body cavity, so that the floating ball moves upward under the buoyancy of water to block the exhaust nozzle, so as to achieve self sealing. The pipeline is in normal operation, Under the action of pressure, the air in the water is continuously discharged into the upper part of the body cavity of the air vent valve, forcing the float ball to descend and leave the original sealing position. At this time, the air is discharged from the exhaust nozzle, and then the float ball returns to its original position for self sealing. Therefore, the valve of the double orifice air vent valve is always open during normal operation, and the float ball keeps repeating the above actions. The air is continuously discharged. When it is necessary to repair or clean the body cavity, the valve should be closed.
The air vent valve is closed when the valve rod is rotated clockwise.
