How to solve the internal and external leakage phenomena of the clamp type fluorine lined butterfly valve

clamp-on Fluorine-lined Butterfly Valve During use, problems are inevitable, such as Clamp type fluorine lined butterfly valve The occurrence of internal and external leakage has an impact on the use of the valve itself. So how to carry out maintenance and solve it? The editor will introduce it to everyone.
When there is internal leakage in the clamp type fluorine lined butterfly valve, you can first check the sealing surface to see if there is any problem, and then treat the sealing surface to see the effect. If there is an external leakage phenomenon, it is relatively easy to handle. For the leakage of the French flange, tighten the bolts of the middle flange again. If it still doesn't work, open the gasket of the middle flange to see if it is damaged. For the leakage of the packing, press the packing tightly. If the packing is too loose, add more packing. The internal leakage of clamp type fluorine lined butterfly valves is generally caused by damage to the sealing surface of the valve seat or valve core. This can be done by grinding the sealing surface of the valve seat or valve core, but there is also a special case where the valve stroke may not be set properly if it is electric or pneumatic. External leakage depends on where it leaks. If the valve body leaks, it can only be replaced.
