 Product Description

Flood gate system is most simply described as a row of steel gate panels supported on their downstream side by inflatable air bladders, by controlling the pressure in the bladders, the pond elevation maintained by the gate can be infinitely adjusted within the system control range(full inflation to full deflation ) and accurately maintained at user –selected set-points.The spillway gate system is attached to the foundation structure by anchor bolt and clamps .there are equal number of air bladder and gate panel sets



-a set of gate panel

-a set of air bladder

-a set of anchor bolt

- a set of automatic inflatable and deflatable system

Operating principle

Block water

Through inflating the air bladder so that can support the steel gate to block water.

Running water

When water runs, the air bladder under the steel panel can be protected from water scouring and flotage attacking

Dam height adjust

Adjust the air pressure to get the required height.


Deflate the air bladder, gate panel and air bladder are both cling to the riverbed and the air bladder was entirely covered by the steel panel. (All of the operation processes can be under automation supervisory system)
