The electric butterfly valve is suitable for applications requiring flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the pressure of the butterfly plate to withstand the pressure of the pipeline medium should be considered. Sex. In addition, the limits of the operating temperature of the elastomeric seat material at elevated temperatures must also be considered. The butterfly valve has a small structural length and overall height, a fast opening and closing speed, and good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making a large diameter valve. When a butterfly valve is required for control flow, the most important thing is to properly select the size and type of butterfly valve so that it can work properly and efficiently. Midline butterfly valves usually require a short structural length and a fast opening and closing speed (1/4 turn) in throttling, adjustment control, and mud media. Low pressure cutoff (small pressure difference), butterfly valve is recommended. In the two-position adjustment, the narrowing channel, the low noise, the cavitation and the gasification phenomenon, a small amount of leakage to the atmosphere, and an abrasive medium, a butterfly valve can be selected. In the case of throttling adjustment under special working conditions, or requiring strict sealing, or severe wear, low temperature (deep cold) and other working conditions, the use of special design metal sealing belt adjustment device for three eccentric or double eccentric special Butterfly valve.
