Single outlet exhaust valve
Single outlet exhaust valves (exhaust valves) are used for pipe exhaust of independent heating system, central heating system, heating boiler, air conditioning, floor heating and solar heating system. Because there is usually dissolved air in water, and the solubility of air decreases with the increase of temperature, the gas gradually separates from the water in the process of circulation, and gradually gathers together to form large bubbles or even gas columns. Because of the supplement of water, gas is often produced.
Working Principle of Single-port Exhaust Valve:
In the exhaust state, the buoy pulls one end of the lever down because of gravity. At this time, the lever is in an inclined state. There is a gap in the contact part between the lever and the exhaust hole, through which air is discharged from the exhaust hole. With the exhaust of air, the water level rises, the buoyant buoyancy of the buoyancy of water buoys the buoyancy of the buoyancy buoyancy buoyancy buoyancy buoyancy buoyancy buoyancy, The vent is blocked. The exhaust valve is then closed.
Advantages of single-port exhaust valve:
1. The float of the exhaust valve is made of low density P P material, which will not deform even if it is soaked in high temperature water for a long time. It will not make the float difficult to move.
2. The lever of the buoy is made of hard plastic, and the connection between the lever and the buoy and the support is made of movable connection. Therefore, it will not cause rust in long-term operation, which will lead to water leakage when the system can not work.
3. The sealing end of the lever is supported by spring, which can expand and contract with the movement of the lever to ensure the sealing without exhaust.
