Structural Features and Advantages of Electric Butterfly Valve
Electric butterfly valve is suitable for situations requiring flow regulation.
The pressure loss of butterfly valve in the pipeline is relatively large, about three times that of gate valve.
Therefore, when choosing butterfly valve,
- The influence of pressure loss on the pipeline system should be fully considered;
- And the firmness of the butterfly plate under the pipeline medium pressure when it is closed should also be considered.
- In addition, it is necessary to consider the working temperature limit of elastic seat material under high temperature.
The structure length and overall height of butterfly valve are small, opening and shutting speed is fast, and it has good fluid control characteristics. The structure principle of butterfly valve is most suitable for making large-diameter valve.
When the electric butterfly valve is required to control the flow, the most important thing is to select the size and type of the butterfly valve correctly so that it can work properly and effectively.
The middle line butterfly valve usually requires a short structure length, fast opening and closing speed (1/4 revolution) in throttling, regulating control and mud medium. If low pressure cut-off is required (small differential pressure), we recommend butterfly valve. The butterfly valve can also be used when there are two position adjustments, contraction of ground channels, low noise, cavitation and gasification, a small amount of leakage to the atmosphere, and abrasive medium. When the butterfly valve is used under special working conditions, such as throttling regulation, strict sealing, severe wear, low temperature (deep cold) and other working conditions, it is necessary to use the special butterfly valve with three eccentric or double eccentric designed metal sealing belt adjustment devices.
