Hydro power Ball Valve Media Water Containing Silt and Quartz Sand

Product Description

Hydro-electric ball valve is mainly suitable for medium containing silt water, temperature -28~80℃ hydropower

station when the water pipe as the opening and closing device, can only be fully open, fully closed, can not be

adjusted with small flow resistance.

The piston water stop ring structure with double sealing rings is adopted, and the upstream maintenance seal

and the downstream working seal are divided. Sealing rings are arranged on both the upstream and downstream

sealing positions of the annular valve core, and the piston stop ring is pushed and pressed by the hydraulic

system to realize the sealing. When the ball valve is closed normally, the downstream working seal is closed and

the water is stopped smoothly, and when the downstream working seal is overhauled or replaced, the upstream

inspection seal is closed and locked by the mechanical locking device.

On the upstream and downstream sealing rings of the ball valve, position travel switches are respectively set.

After connecting to the central control room through the circuit, the state of the sealing ring can be accurately

understood, so that the relay switch valve can be accurately operated.

The upstream of the hydraulic ball valve (main valve) is welded with the water inlet pipe through the short pipe

in front of the valve, and the downstream is connected to the volute of the turbine through the expansion joint,

so as to facilitate the installation and maintenance of the hydraulic ball valve (main valve) and the adjustment

of the expansion joint.

The hydraulic ball valve (main valve) is provided with a bypass production pipeline, the purpose of which is to

balance the pressure at the upstream and downstream ends of the valve before opening the main valve, and

reduce the opening and closing torque of the main valve. The bypass valve is a hydraulic ball valve, and a

manual valve is set in front of the hydraulic ball valve for overhauling the bypass hydraulic ball valve.

Feature

Soft Seal Trunnion Mounted Ball Valve

If fluid medium is clean water without sediment and silica sand etc, it is good choice to use soft material seal

fixed ball valve which will ensure no leak after closure fluid so that properly safety for the downstream unit overhaul.

Metal to metal Seal Trunnion Mounted Ball Valve

If water in the hydropower station with high content sediment and silica sand , it is better to choose metal to metal

seal fixed ball valve for prolong unit life time.metal to metal seal hydropower ball valve uses metal hard-face seal,

piston seal and toroidal seal structure, includes upstream overhaul seal and downstream work seal. also you can

choose electric actuators like LTMITORQUE,ROTORK,BIFFI,AUMA,SIMENS,TETDF brands , which will help your

projects such better in automaticity occasion.

Hydraulic Actuator

Hydraulic cylinder,piston body and shifting fork compose the waterproof actuator so that no need to build valve chest

which saves your project cost. also we can configure ball valve control cabinet ,oil pressure installation,leakage oil

device for you.

Electric Actuator

We can configure PLC electrical control room according to your requirement.
