QB1-10P Stainless steel air vent valve Working principle

QB1-10P Stainless steel air vent valve is mainly composed of valve body, valve, upper cover, valve stem, float ball, exhaust nozzle, etc. When the gas in the pipeline needs to be discharged, the air in the pipeline enters the body cavity under the action of water pressure, and is discharged from the exhaust nozzle, then the water in the pipeline is filled with the body cavity, so that the floating ball under the action of water buoyancy, moves upward to plug the exhaust nozzle, to achieve self-sealing, the pipeline in the normal line, the air in the water under the action of pressure, constantly discharged into the upper body cavity of the exhaust valve, Force the float down, leave the original sealing position, then the air is discharged from the exhaust nozzle, and then the float returns to the original position and self-sealing, therefore, QB1-10P Stainless steel air vent valve is always open in normal operation, the float repeatedly repeats the above action, and the air is constantly discharged. When the body cavity needs to be repaired or cleaned, the valve should be closed.
