H41HLift Check ValveH41H lift check valve is widely used in water treatment, chemical industry, petrochemical industry, petroleum, papermaking, mining, electric power, liquefied petroleum gas, food, pharmaceutical industry, water supply and drainage, municipal government, electronics, urban construction, environmental protection, fire fighting, heating and ventilation, Central air conditioning, filtration equipment and other fields.
Structural characteristics
- Lift check valve has the advantages of simple structure, reliable action, easy maintenance and so on.
- When the medium from the valve body arrow shows the direction of flow into the valve body, the pressure of the medium on the valve flap to produce upward thrust, when the medium thrust is greater than the gravity of the valve flap, the valve is open. When the pressure of the medium after the valve on the force of the valve plus the valve's own gravity is greater than the pressure before the valve on the force of the valve, the valve is closed to prevent the medium from flowing backward.
- The sealing surface is not easy to wear, abrasion, better sealing, longer life.
