Butterfly valve is a common fluid control device, so what is its main role
1. Adjust the flow rate: the butterfly valve adjusts the flow rate of the pipeline medium through the opening of the butterfly plate, so as to achieve the flow control of the fluid. When the butterfly plate is fully opened, the fluid can pass through without hindrance to achieve a large flow rate; When the butterfly plate is partially open, the opening area of the fluid through the butterfly plate is reduced, so as to adjust the flow rate.
2. Adjust the pressure: when the closure of the plate increases, the flow in the pipeline is limited, so that the control of the medium pressure can be achieved.
3. Reverse flow blocking: The butterfly valve has a reverse flow blocking function. When the medium flow direction changes, the butterfly valve can automatically close to avoid the reverse flow of the medium, thus protecting the pipeline system.
4. Change the flow direction: the butterfly valve can change the direction of the medium flow by changing the position of the butterfly plate to achieve the flow control of the pipeline system.
5. In addition, butterfly valve also has the advantages of simple structure, flexible operation, good sealing, light weight, small flow resistance, etc., so it is widely used in food, medicine, chemical industry, water treatment and other fields. In the selection of butterfly valves, full consideration should be given to the impact of the pipeline system by pressure loss, as well as the robustness of the butterfly plate to withstand the pressure of the pipeline medium when closed, and the limitation of the elastic seat material to withstand the operating temperature at high temperatures. At the same time, according to different use occasions and needs, choose the appropriate type and size of butterfly valve to ensure its effective working performance.
