Product Description

Pneumatically operated spillway gate (air bladder support gate)
 
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 much safer under the gate panel cover.  

Gate panel 
Material: stainless steel, carbon steel
Size: 5m or 6m per unit
Structure: made of steel panel above 16mm thickness, arc, reinforced ribs on the surface 
Corrosion protection: thermal spray zinc and seal coating or polyurea material. 

Air bladder 
Material: Air bladder is made of tyre fabrics and special rubber. 
Performances: W.P. 0.07-0.20MPa, designed pressure 1.0MPa, designed safety factor 8-10 times, out layer EPDM, aging resistant over 30 years.                            
 
Control system 
Intelligent control system functions:
1.    real-time dynamic display of operation status 
2.    intelligent fault alarm, easy for repair. 
3.    one key start-stop, simple operation 
4.    intelligent data analysis, optimize the operation and management. 
5.    intelligent PLC could realize the data transmission and local control.  
6.    monitoring the running status by mobile App is available. 
7.    remote monitoring could realize the unmanned control.   
8.    manual and automatic dual control.
