The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. The butterfly valve is simple in structure, small in volume and light in weight. It is composed of only a few parts. It can be opened and closed quickly only by rotating 90 degrees. It is easy to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in full open position, the butterfly plate thickness is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.
If butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of butterfly valve is especially suitable for making large caliber valves. Commonly used butterfly valves are butterfly valves and flange butterfly valves. The clamp butterfly valve is connected between two pipeline flanges by double-head bolts. The flange butterfly valve is connected with flanges on the valve. The flanges on both ends of the valve are connected with bolts in the process of using the pipeline flanges.
