II. What is an HDPE Flap Valve? Structure and Operation
1. Definition
An HDPE flap valve is a device installed at the outlet of drainage systems or ditches, allowing water to flow out but preventing water from the outside (such as heavy rainfall or tidal surges) from flowing in.
2. Basic Structure
-
Valve body: Made from solid HDPE, resistant to force
-
Flap: Designed to open and close flexibly with water flow pressure
-
Rubber sealing gasket: Helps seal when the valve is closed, preventing odors and backflow
-
Stainless steel pivot: Ensures durability and rust resistance
3. Operating Mechanism
The valve operates completely automatically, requiring no electricity or mechanical force. When water flows out from the drain, the pressure automatically pushes the valve open; conversely, when the flow stops or external water rises, the valve closes immediately.
