What is the function of butterfly valve

Butterfly valve is a commonly used control valve, mainly used to regulate the flow and pressure of fluids. Its role includes the following aspects:

1. Control flow rate: The butterfly valve can change the flow rate of the medium through the pipeline by rotating the valve plate. The opening degree of the valve plate determines the channel area of the fluid through the valve, thus controlling the flow rate.

2. Adjust the pressure: The butterfly valve can also adjust the pressure in the pipeline by changing the resistance of the fluid through the channel. By adjusting the opening degree of the valve plate, the resistance of the fluid passing through the valve can be increased or decreased, thereby regulating the pressure level in the pipeline.

3. Cut off the pipeline: the butterfly valve can completely close the channel to achieve the cut off and cut off of the fluid. When it is necessary to stop or isolate the fluid in the pipeline, this can be done by closing the butterfly valve.

4. Adjust the direction of the fluid: The structure of the butterfly valve allows it to change the flow of the fluid. By rotating the valve body, the flow direction of the medium in the pipeline can be changed to meet the specific process requirements.

In short, butterfly valves have a wide range of applications in industrial production, water treatment, water supply heating and other fields, and can achieve accurate control of fluid flow, pressure and flow direction.
