The pneumatically operated spillway gate is a new type hydraulic structure, which can simultaneously satisfy the safety of retaining water and stepless adjustment of discharging water level.
Operation principle
1. Retaining water: inflated the air bladder, it will support the gate panel stand up, and realize retaining water.
2. Overflow: when the water level higher than the gate panel, the water flow and floater will pass on the gate panel. The air bladder will not destroy because of the gate panel protection.
3. Adjust the dam height: through adjust the inflated air pressure, to achieve the purpose of adjust the support angle of the gate panel, and finally control the water level.
4. Collapse: deflate the compressed air in the air bladder, the gate will collapse. The gate panel and air bag will next to the riverbed, the support system is more safer under the gate panel cover.
· The main features of the Spillway gate are:
· Modular design means that very long spans can be installed
· Single components can easily be replaced if damaged
· Steel panels protect the air bladders from damage
· Can be operated at any height from fully inflated to fully deflated
· Independent operation of different gate sections is possible
· Installation is straightforward. The inflation/deflation system is intuitive and operation can be performed by any competent technician following a short time training.
· Simple, effective, and environmentally-friendly water retention system .
· APPLICATIONS
· Hydroelectric Power, Irrigation, Flood Control, Water Supply, Water Cooling, Separation of Fresh and Sea Water, Navigation Channels, Recreational, Ground Water Recharging, Urban Regeneration.
