The middle part of it looks like a cavity. Inside, there’s a duckbill-shaped valve flap—this is the core part that lets fluid flow in only one direction. When fluid flows forward, the valve flap opens up. When fluid tries to flow backward, the valve flap shuts tight.Flat wing structures stick out from both sides of the valve.
