AI Technical Summary
Traditional flue gate valves lack a fall prevention structure after the gate is opened and returned to its original position, which may cause the gate to fall and pose a safety hazard.
A drive motor and a lead screw are used to control the anti-fall pin on the moving block. After the plate is opened and returned to its original position, the pin is inserted into the socket of the pin holder to fix the plate and prevent it from falling.
This improves the safety and stability of the flue gate valve, prevents the gate from falling, and enhances the overall structural safety.
