Check valve use for a long time, the sealing surface more easily damaged parts, so when the check valve sealing surface is damaged, how are we going to solve? 1. Sphere rushed over and assembly should be correct, smooth operation, do not allow the throttle Industrial Valves can be used, ball impact should be processed in a timely manner after the repair, replace a seal. American standard check valve according to the conditions of use, valve can be all-metal structure, can also be embedded in disc shelves rubber mat or rubber ring form. Forged steel check valve used for industrial piping block medium counter-current device. Swing check valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping. 2. Crushed on sealing surface, tighten the seat bolts should be uniform, force is smaller, the better to close a few times more, inevitably a tight too much time is too tight, damage the sealing surface of crapping to repair can be performed. 3. Sealing surface structure without preload pressure, valve seat sealing surface should organize regular inspection control pre-tightening device pressure, found through sealing face ever leak or contact should be a little loose pressure valve seat sealing surface, in the process of the preloading spring effect loss and replacement. 4. Wrench, as between the stem and ball joint clearance, wrench has to the user, shut down and sphere rotation Angle space information leakage of less than 90 degrees, limited protection agency of wrench, stem and a sphere model are mutually joint is loose and when clearance is too large, should repair, fastening tightly; Adjust good state limit block, remove the adjustable wrench is advance Angle, make sphere form the correct opening and closing. Therefore, when the check Industrial Valves sealing surface failure occurs, we need to use the right way to solve, thus ensuring role in production.
