Application of how to deal with the globe valve leakage or leakage, leakage and good processing, for the leaking flange, the flange bolt in the tight again, if not yet, will be open to see there is no damage to the flange gasket, packing to leak, important gland, if the packing is too loose, will add the packing, if the leakage is directly on the body, low pressure can weld, if it is a high pressure will directly give it up, safety first, for internal leakage problem, well, first of all, may not related to death, and closing the hard, second, the seat seal is damaged, this will be reground, for the valve core, want to see is hit by medium erosion damage or damage, but both need to repair welding sealing surface. Internal leakage is generally valve seat or valve core sealing surface damage, this can grind the valve seat or valve core sealing surface, but there is a kind of special situation if either electric or pneumatic Industrial Valves stroke likely didn't set well. Leakage to see where is the leakage and if the Industrial Valves body can only change the valve leakage. Leakage should be seal face problems, put the look at the effect of the seal face with the leakage, the valve is different, different leakage location, to discriminate filler leakage, tight or replacement of packing, we are using this a lot of time can't stop the online leak sealing. Cut-off valve has a lot of leakage points, leakage in most cases from gland leakage, open the gland supplement or replace the packing gland to tighten up should not leak. Leak is inside the top of the valve core sealing surface is broken, but practical experience tells us that sometimes leak likely card on the Industrial Valves core is a good thing, cause of leakage, specific treatment method is to open and close the valve, back and forth several times washed away the hard objects. If the valve is its own problems, we should choose the appropriate time to replace the valve.
