2, pneumatic butterfly valve installation of a flange suggested that appropriate and use the special place of butterfly valves, namely HGJ54 - The type 91 socket welding steel flange. Pneumatic butterfly valve tightly closed surface leakage fault out: 1, the butterfly plate, tightly closed 2, butterfly plate surface with debris, tightly sealed closed position match against three, export side is equipped with uneven pneumatic butterfly valve flange bolt out of two transverse leakage fault: Marine valve 1, deprived tight sealing gasket on both sides of 2, uneven tube flange force or pressure 3, tightly closed circle of upper and lower sealing gasket lose effectiveness. 6, seizing the connection parts required pressure, namely guarantee packing tightly closed, but also guarantee the valve stem flexible rotation. 。 【 Q 】 Pneumatic butterfly valve fault out method' A 】 Pneumatic butterfly valve in the exposed problems, we should how to troubleshoot, at the same time, in the shortest possible time for mesh explanations of the roots of this problem and the problem of? Here will bring you explain the answer! 1, before installation should be clearly acknowledged SENMI product quality character and medium to flow direction arrow is consistent with the working condition of yun xing, and the body will wash clean, not allowed in tightly closed circle and butterfly plate with foreign impurities, before cleaning is not allowed to close the butterfly plate, lest destroy tightly closed circle. 3, pneumatic butterfly valve installed in the pipeline position, the best location for the vertical loading, but you can't flip. Seven pneumatic butterfly valve, metal tightly closed uncomfortable or installed on the end of the line, such as must be installed in the end of line, take equipped with export hair, avoid the backlog of tightly closed circle, too. 8, install use echo regularly seizing the valve stem effect, find fault out early. 4, pneumatic butterfly valve used needs to adjust the flow rate, execute stem with pneumatic actuators. 5, back to the opening and closing more manual butterfly valve, in 2 months time, open the worm gear case cover, seizing ghee is normal, should maintain the appropriate number of trades.
