Working principle of single port exhaust valve
When water starts to be injected into the pipe, the float will slowly rise upwards, and at this time, the valve has been vented. When a certain pressure is reached, the floating ball tightly presses against the rubber ring, indicating that all the air has been discharged from the exhaust nozzle.
