Product details

PRODUCT OVERVIEW

The accumulator type hydraulic control slow closing 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 this valve adopts energy storage tank to replace the 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 consumed to support the heavy hammer for long-term operation, The pressure holding performance of the hydraulic system is improved. It is mainly installed at the inlet of the turbine of the hydropower station and used as the inlet valve of the turbine; Or installed at the pump outlet of various pump stations such as water conservancy, electric power, water supply and drainage to replace the role of check valve and gate valve. During operation, the valve cooperates with the pipeline host, according to the principle of hydraulic transition process and through the preset opening and closing procedure, so as to realize the reliable cut-off of the pipeline, effectively eliminate the pipeline water hammer and protect the safety of the pipeline system. The valve is suitable for water, seawater, oil and other non corrosive fluid media. It can be used for check and stop functions at the outlet of the pump or pipeline.

PRODUCT FEATURES

1. The energy is stored by two accumulators, and the valve can be closed automatically when there is no external energy.

2. Reliable sealing and small flow resistance coefficient.

3. The PLC intelligent control system can realize a variety of humanized operation interfaces such as text and touch screen.

4. Remote and local control can be realized.

5. It can realize linkage operation with other pipeline equipment according to predetermined procedures.

6. It has fast and slow adjustable closing function.

7. It has stop and check functions.

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