Quick Exhaust Valve

Quick exhaust valve is based on the buoyancy characteristics of water on stainless steel floating ball When the water level in valve rises, the floating ball will automatically float up under the buoyancy of water until it is connected with the sealing surface of the exhaust port. When the water level in valve decreases, the ball will drop with the water level. At this time, a large amount of air will be injected into the pipe through the exhaust port. After being installed on the pipe, the ball will automatically open / close the exhaust valve by using the inertia of water to the floating ball Air port.

3. Advantages of Quick Exhaust Valve

1) The pontoon of quick exhaust valve is made of low density PP material, which will not deform even if it is soaked in high temperature water for a long time. It will not make the buoy difficult to move.
2) Quick exhaust valve pontoon lever is made of hard plastic, and the connection between the lever and pontoon and support is movable, so it will not rust during long-term operation, resulting in water leakage due to system failure.
3) The sealing end face of quick exhaust valve lever is supported by spring, which can expand and contract with the movement of lever to ensure the sealing without exhaust.



4.Quick exhaust valve scope of application

Quick exhaust valve is applicable to the pipeline with industrial medium of water. It is a necessary equipment for the pipeline to quickly remove the gas in the pipeline, so as to improve the efficiency of water transportation equipment and protect the pipeline from deformation and fracture. Quick exhaust valve is widely used in independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.
