The butterfly valve of the pneumatic butterfly valve powder system is used for the control of solid materials. It is often used as a emptying valve at the bottom of the tank, such as the bottom of cement tank, stone powder tank, etc., for emptying and rapid plugging. Because most of the dust materials contain large or small particles, there is no doubt about the wear of the valve sealing surface. Improper selection will greatly reduce the service life of the valve, or quickly form internal leakage of the valve, affecting the continuous use. For the batching and weighing system, the whole batching process is automatically controlled by PLC, while the feeding valve of the batching trolley is a pneumatic triple bias butterfly valve, and the medium is very fine stone powder. After using for a period of time, the valve leaks inside, causing the stone powder to leak on the workbench in piles. This medium is very thin and a little sticky. Although the batching trolley is equipped with an oscillating motor, there are many materials attached to the tank wall and the valve. When the valve is closed, it is stuck around the sealing surface, so that the valve cannot be completely closed, As a result, leakage occurred after adding materials from the beginning, and the sealing surface was severely worn all day long, even showing grooves.
