Flange butterfly valve leakage problem solution

Flange butterfly valve leakage problems: In the screw conveyor to the reactor with powder feeding the lower tube installed a pneumatic butterfly valve, the reaction process will be part of the solvent (acetone) evaporation 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. Flange butterfly valve to solve the problem: the fundamental reason for the 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. Test flexible flange butterfly valve, the pressure ring this side up flat, placed in this plane and a flange outside the park, the valve through the same size of the plate, if the test press, the pressure to be pressed This pressure plate, so that the pressure evenly distributed on the pressure ring on the side of the body. If it is to use blind test, the general butterfly valve flange are used to clamp two flanges for clamping test, flange flexible flange butterfly valve sometimes, only for the convenience of the user with a flange below And the valve bolt fixed, then the body of the pressure ring above the fixed screw to withstand the full pressure of the medium, as mentioned earlier, these few screws can not withstand the pressure of all the media, so with a blind Test valve does not leak, but also the same as the actual state base.
