Hydropower Station Type Hydraulic Control Butterfly Valve

Hydropower station type hydraulic control butterfly valve is widely used in the inlet of water turbines in medium and small hydropower stations. It can automatically operate according to the program, connect and cut off the water flow, prevent the turbine from flying away, and reduce the water hammer.

The opening of the Hydropower Station Type Hydraulic Control Butterfly Valve is driven by hydraulic pressure, and the oil pressure can reach 16MPa, which reduces the volume of the swing cylinder. Lift the weight while opening the valve, and the reliable mechanical locking device will be put into operation automatically after fully opening. After receiving the signal to close the valve, the solenoid valve will act, unlock automatically, and automatically close according to the program under the action of the heavy hammer torque, without power oil source, canceling the energy storage tank, simple and reliable, and greatly simplifying the hydraulic system.

The Hydropower Station Type Hydraulic Control Butterfly Valve adopts double eccentric disc. The horizontally installed valve shaft is elevated by a certain distance on the center line of the pipeline, so that the water facing area of the lower half of the valve plate is larger than that of the upper half. When the valve is closed in an emergency, the power water can be used to help the valve close to reduce the weight of the hammer. The oil pressure device with simple structure and small size, the electric automatic control box, the swing oil cylinder, and the control oil pipe are integrated with the valve in a very compact way, without additional configuration by the user, the cost is greatly reduced, and the floor space is saved.

The Hydropower Station Type Hydraulic Control Butterfly Valve is equipped with a hand pump and a manual valve closing device, which can manually open and close the valve during maintenance or when there is no electricity. The opening and closing time of the valve can be adjusted, which can meet the needs of adjustment and maintenance, and ensure the safe and reliable operation of the water turbine unit. The electrical automatic control box of Baidai can realize local, remote and automatic control operations, meeting the requirements of "no one on duty, few people on duty" in the power station.
