One. HD7x41X accumulator type liquid control slow closing butterfly valvepurposes

Hydraulic check butterfly valve is currently the more advanced control equipment, mainly used in hydropower station, water pump room and electricity, petroleum, chemical, metallurgy, mining and other types of pumping stations installed in the turbine inlet or outlet pipe, For the deadline, only use.

 

Two. HD7x41X accumulator type liquid-controlled slow-closing butterfly valve features

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

2, destructive water hammer can be eliminated to prevent the pump and turbine runoff occurred, effectively reducing the pressure fluctuations in the network management system to ensure the safe and reliable operation of equipment.

3, the valve can replace the pump outlet of the original electric gate valve and check valve function, reduce the area and infrastructure investment. At the same time, its flow resistance coefficient is only 0.1 ~ 0.6, far less than the flow resistance coefficient of check valve (1.7 ~ 2.6), energy-saving effect is obvious.

4, the company S (lock type), B (dwelling type), X (accumulator type) three types of liquid control check butterfly valve products are different ways to solve the domestic similar products under heavy hammer Disadvantages, greatly enhance the reliability and security of the system. At the same time, the company can be individually designed according to the special requirements of users, multi-faceted to meet the needs of users of such products. D.HD7x41X accumulator type hydraulic control slow closing butterfly valve main performance parameters.
