    product description

    When there is gas overflow in the system, the gas will climb up the pipeline and eventually gather at the highest point of the system. The air vent is generally installed at the highest point of the system. When the gas enters the air vent cavity, it gathers at the highest point of the air vent. At the upper part, as the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will drop the water level in the cavity, and the float will drop with the water level, opening the air port; after the gas is exhausted, the water level will rise and the float will also As it rises, the air port is closed. In the same way, when negative pressure is generated in the system, the water level in the valve cavity drops and the exhaust port opens. Because the outside atmospheric pressure is greater than the system pressure at this time, the atmosphere will enter the system through the air port to prevent the harm of negative pressure. If the bonnet on the valve body of the air vent is tightened, the air vent stops exhausting. Normally, the bonnet should be in an open state. The air vent can also be used in conjunction with the block valve to facilitate the maintenance of the air vent.
