Hydraulic control check butterfly valve-Butterfly valve series-蝶阀厂家-上海冠环阀门制造有限公司

Product description

The heavy hammer type hydraulic control check butterfly valve is mainly installed in the inlet of the hydropower station turbine and is used as the inlet valve of the hydropower station; Or installed in the outlet of the pump in various pumping stations such as water conservancy, electric power, water supply and drainage, replacing the role of check valve and gate valve. When working, the valve cooperates with the pipeline host, according to the principle of hydraulic transition process, through the preset opening and closing procedure, to achieve reliable cut-off of the pipeline, effectively eliminate the water hammer of the pipeline, and play a role in protecting the safety of the pipeline system. The valve is suitable for water, seawater, oil and other non-corrosive fluid media, and can be used for start-stop and shut-off functions in the outlet or line of the pump.

Structural features

1. It can replace the outlet globe valve and check valve of the water pump, and integrate machine, electricity and hydraulic, and occupy a small area.
2. High degree of automation, can be local, remote and linkage control.
3. The electrical system can adopt PLC intelligent control system or ordinary relay system.
4. The hydraulic system motor has low power, high work efficiency, good pressure holding performance, and long oil pump start interval.
5. The hydraulic system has automatic pressure holding function, long pressure holding time, and the oil pump starting interval can reach 500 hours.
6. There are obvious opening indication and mechanical limit adjustment mechanism, stroke switch device waterproof and dustproof design, not exposed, stable performance, long service life.
7. The electrical operation interface is humanized and diversified, and ordinary buttons, text and touch screen can be designed, and the man-machine operation interface can be designed according to the needs of customers.
