Steel double-leaf flap valve

A steel double-leaf flap valve is a one-way valve installed at the end of a pipeline, primarily used to prevent backflow of external water and features an automatic closing function. Its core structure consists of a door plate, hinges, door seat, and sealing components, which operate based on the pressure difference of the medium to open and close without manual intervention.
Structural Features
Steel double-leaf flap valves typically adopt a double-hinge design, with the door plate connected to the door seat via hinges, and the sealing components often made of rubber. Their tightly sealed structure makes them suitable for applications in water conservancy systems, municipal sewage, flood control, and drainage.
Applicable Scenarios
Water Conservancy Systems: Used to prevent backflow from rivers and tidal waters.
Municipal Engineering: Such as urban water supply and drainage, and inter-basin water transfer.
Industrial Applications: Such as water supply systems in industrial and mining enterprises.
