Single-port exhaust valveadmin
Single-port exhaust valve used in independent heating system, central heating system, heating boilers, central air conditioning, floor heating and solar heating system pipe exhaust. Because some water, usually dissolved air, and the air solubility decreases with increasing temperature, so that the gas is gradually separated from the water in the water of the for loop, and gradually together to form large air bubbles or column, because there are make-up water, so often gases.
When the state of the exhaust gas, the float by gravity, down one end of the lever down, when the lever is in the inclined state, the lever voids exhaust hole contact portions, the gap through which air is discharged from the vent hole, as the air discharge, the water level rises, the float float up under buoyancy of water, seal face gradually the pressure on the lever on the vent, until the entire exhaust vent was completely blocked. Then the exhaust valve is in completely closed state.
