Name | Water Meter Check Valve |
Function | Prevent water backflow, ensuring water only flows from the supply pipe to the user end. For example, in a building water supply system, it stops water from downstairs pipes flowing back during outages. |
Working Principle | With a movable valve flap. When water flows forward, the flap is pushed open by water pressure. When backflow occurs, the flap closes due to backflow pressure. |
Types | Swing Check Valve: Valve flap rotates around an axis, suitable for large-diameter pipes with low flow resistance. |
Lift Check Valve: Flap moves vertically, has simple structure and good sealing, often used in small residential installations. | |
Butterfly Check Valve: Flap is disc-shaped, small, light and space-saving. | |
Installation Precautions | Must be installed with the correct direction as indicated by the arrow. The installation position should be near the user end after the water meter and with a firm and sealed pipe connection. |
Maintenance and Common Problems | Regularly check the working state. Common issue is impurity blockage. Sediment and rust may accumulate and affect the flap's movement. Can be solved by regular cleaning or using a pre-filter. |
