Description

Technical Field

[0002] The exhaust valve is used for exhaust of pipelines in independent heating systems, central heating systems, heating boilers, central air conditioners, floor heating and solar heating systems;

[0003] The exhaust valve is usually installed at the highest point of the system. When the gas enters the exhaust valve cavity, it gathers at the upper part of the exhaust valve. As the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will cause the water level in the cavity to drop, and the float will drop with the water level, opening the exhaust port. After the gas is exhausted, the water level rises, and the float also rises, closing the exhaust port.
