Processing by pneumatic valve leakage or leakage 4)

leak a better deal, for the flange leakage, to tighten the flange bolt, if not enough, we must open and see whether have damage, leakage in packing flange gaskets, packing gland must bear if packaging is too loose, must fill in, if leakage directly on the body, low pressure, then you can welding, high pressure directly give it up, if the leakage problem, safety first is not determined in the first place, it may not be related to death and then forcibly close second, pneumatic valve seat seal is broken, needs to be polished, pneumatic valve core is damaged, it erosion destruction of or damage to the impact of the media, but have to welding sealing surface. Generally in pneumatic seat sealing surface leakage or damage to the pneumatic valve core, it can grind pneumatic seat or pneumatic valve sealing surface, but there is a special case, if it is electric or pneumatic valves, pneumatic is likely to be no fixed schedule. Leakage, depending on leakage, even if just for drainage pneumatic valve pneumatic valve body. If internal leak sealing surface should be a problem, solve it, see the effect of sealing surface
