Single port exhaust valve (exhaust valve) is used for pipeline exhaust of independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system. Because a certain amount of air is usually dissolved in the water, and the solubility of air decreases with the increase of temperature, so that the gas gradually separates from the water in the process of water circulation and gradually gathers together to form large bubbles or even gas columns. Due to the supplement of water, gas is often generated.

In the exhaust state, the pontoon pulls down one end of the lever due to gravity. At this time, the lever is in an inclined state. There is a gap between the lever and the exhaust hole, and the air is discharged from the exhaust hole through this gap. With the discharge of air, the water level rises, the pontoon floats upward under the buoyancy of water, and the sealing end face on the lever is gradually pressed against the exhaust hole, Until the entire vent is completely blocked. The exhaust valve is now completely closed.
