Details

1. Main operating indicators:
The opening water level is 10-30 higher than the top of the gate CM
Return valve water level 0.7-0.8 valve height
The normal water retaining level is equal to or slightly lower than the elevation of the gate top
It can be synchronized or continuously overturned and reset in a short time.
2. Schematic diagram of action principle:
① In flood season, when the water level at the top of the gate reaches 10-30cm, the door panel starts to start.
② The flap door starts to start.
③ With the increase of flood volume, the discharge area of the flap door will increase until it is completely overturned for flood discharge.
④ As the flood water level drops, the overflow area of the flap door automatically decreases, and then the water retaining is reset to restore the water storage level to the start state. (As shown in the figure)
