Accumulator type hydraulic controlled slow closing check butterfly valve,Accumulator Type Hydraulic Slow Closing Butterfly Valve.Accumulator type return butterfly valve

Product characteristics

1, by two accumulators to store energy, no external energy can automatically close the valve.

2, reliable sealing, flow resistance coefficient is small.

3, the use of PLC intelligent control system, can achieve text, touch screen and other user-friendly operation interface.

4, can achieve remote and local control.

5, can achieve linkage operation with other pipeline equipment according to the predetermined program.

6, with fast, slow adjustable closing function.

7, with cut-off, check function.

8. It can realize the slow closing function when closed, effectively eliminate the harm of the water hammer, and protect the safety of the pump and the network management system.

The accumulator type hydraulic control slow close check butterfly valve has a relatively perfect hydraulic system and electrical control system, which can be operated on-site or remotely. The control system of the valve uses an energy storage tank to replace the current heavy hammer produced by domestic peer manufacturers, and changes the potential energy of the heavy hammer into fluid energy storage, which not only saves the energy used to support the heavy hammer for a long time, but also improves the pressure retention performance of the hydraulic system. Mainly installed in hydropower station turbine inlet, used as turbine inlet valve; Or installed in the water conservancy, power, water supply and drainage of various pump stations pump outlet, instead of the role of check valves and gate valves. When working, the valve is cooperated with the pipeline host, according to the principle of hydraulic transition process, through the preset opening and closing procedure, the reliable cutoff of the pipeline is realized, the pipeline water hammer is effectively eliminated, and the pipeline system is protected. The valve is suitable for water, seawater, oil and other non-corrosive fluid media, and can be used in the pump outlet or pipeline start, stop and stop function.
