Automatic venting valve: A valve installed at the high point of the system to release the air pockets generated in the heating system and the water supply pipe. The automatic venting valve is widely used in water separators, radiators, floor heating, air conditioning and water supply system.
The working principle of the automatic exhaust valve: When there is air in the system, the gas collects in the upper part of the exhaust valve, the gas in the valve accumulates, and the pressure rises. When the gas pressure is greater than the system pressure, the gas will lower the water surface in the cavity, and the float will follow The water level drops together and the exhaust port is opened; after the gas is exhausted, the water level rises and the float rises, closing the exhaust port. If the bonnet on the valve body is tightened, the exhaust valve stops venting. Normally, the bonnet should be open. It can also be used with the block valve to facilitate the maintenance of the exhaust valve.
The function of the automatic exhaust valve: During the operation of the HVAC system and the HVAC system, many adverse effects caused by the release of water such as hydrogen and oxygen during heating can damage the system and reduce the thermal effect. If these gases are not timely Discharge will have many negative consequences. Such as: corrosion caused by oxidation; formation of air pockets in the radiator; unbalanced hot water circulation, so that some radiators are not hot locally; noise when the pipeline is running with gas; vortex phenomenon of circulating pumps. Therefore, the exhaust gas in the system must be discharged in time, which shows the important role of using the automatic exhaust valve. |
