Keywords: Valve packing Sealant injected into the stuffing box will be able to eliminate the valve packing leakage, the specific operation by three methods. 1, G-type fixture + drilling 1) G-clamp selection of the valve packing box in the appropriate place (usually in the middle). 2) Connect a long drill bit of φ3-φ4mm with a charging drill (or pneumatic drill) and drill into the stuffing box through the G-type clamp to drill stuffing box. 3) Tighten the stuffing box gland nut to allow the gland to move up to increase the space for the stuffing box. 4) access injection gun injection sealant, you can eliminate leakage. 5) G-type fixture can be removed after an hour, can also be removed immediately after the leak, quickly riveted with aluminum rivets. Then tighten the stuffing box gland bolts, plugging ends. This method is easy to operate, widely used. For low pressure, the smaller diameter of the valve. 2, tapping drilling + injection valve 1) with a gas drill in the middle of the stuffing box φ8.4 deep 12mm-15mm hole. 2) tapping thread with M10 tapping. 3) Screw the M20 / M10 injection valve into the screw hole and place the injection valve in the "on" position. 4) Recharge drill (or inflatable drill) connected to the long drill bit φ3-φ4mm, through the injection valve to the stuffing box through-hole. 5) Loosen the packing gland nut to allow the gland to move up to increase the packing box space. 6) Insert the injection gun into the sealant until the leak is eliminated. 7) Close the injection valve, remove the injection gun and tighten the gland packing nut, plugging ends. This method is suitable for larger diameter valves. 3) Fixture + injection valve 1) According to the external dimension of the middle part of the stuffing box of the valve, it is designed to fasten the ring jig on it. This method is suitable for occasions with high pressure and high leakage medium explosion proof grade. 2) Screw in the jig injection hole with an injection screw plunger, injection valve, or both, bringing it into tight contact with the stuffing box. 3) Through the injection valve (or injection mandrel), with φ3-φ4mm long drill to the stuffing box through-hole. 5) Loosen the packing gland nut to allow the gland to move up to increase the packing box space. 6) Insert the injection gun into the sealant until the leak is eliminated. 7) Close the injection valve, remove the injection gun and tighten the gland packing nut, plugging ends.
