Structural characteristics

Liquid-controlled slow-closing check butterfly valve is the more advanced pipeline control equipment at home and abroad, mainly used in hydropower stations, water supply pumping stations and other types of pumping stations for electric power, petroleum, chemical industry, metallurgy, mining and other types of pumping stations, installed in the turbine inlet or pump outlet pipeline for the cut-off, check, adjustment. The valve has the following characteristics:

1, can be opened and closed according to the program, in the normal power supply and sudden power failure can be automatically according to the rated time and angle of fast, slow two-stage closure; adjustment range, adaptability.

2、It can eliminate destructive water hammer, prevent pumps and turbine units from escaping accidents, effectively reduce the pressure fluctuation of the pipeline network system, and ensure the safe and reliable operation of the equipment;

3, the valve can replace the original electric gate valve and check valve at the outlet of the pump, reducing the floor space and infrastructure investment. At the same time its flow resistance coefficient is only 0.1 ~ 0.6, much smaller than the flow resistance coefficient of the check valve (1.7 ~ 2.6), energy saving effect is obvious.

4, the company's S (locking type), B (pressure-retaining type), X (accumulator type) series of liquid-controlled slow-closing check butterfly valves are similar products in the country to improve and perfect the development of a new generation of products, greatly enhancing the reliability and safety of the system. At the same time, the factory can be individually designed according to the user's special requirements, multi-directional to meet the needs of the majority of users of such products.
