Butterfly valve leakage and offset treatment options
Butterfly valve leakage problem: In the use of screw conveyor powder to the reactor under the tube installed a pneumatic butterfly valve, the reaction process will be part of the solvent (acetone) evaporated back. If the butterfly valve leakage, that is, increase solvent loss, but also easy to make the powder material in the material caking, clogging pipes. Butterfly valve to solve the problem: the root cause of butterfly valve leakage is the selection problem. Sealing materials from the butterfly valve inside the form is divided into soft seal and hard seal. If dust caking can not be avoided, other types of valves should be considered.
