The leakage at the joint of the vacuum ball valve sealing ring generally has the following factors:
The sealing ring is not tightly rolled;
The sealing ring connection thread, screw and pressure ring of the ball valve are loose;
The sealing ring of the valve is corroded.
The sealing ring is welded to the body, and the surfacing quality is poor;
The above conditions are likely to be the leakage of the sealing ring connection during the use of the vacuum ball valve. For the above, we can inject the adhesive at the sealing and rolling part of the valve and then roll and fix it; the sealing ring should be in accordance with the welding specifications Re-welding puzzled. When the surfacing welding cannot be repaired, the original surfacing and processing should be removed; then the screws and the pressure ring should be removed to clean, the damaged parts should be replaced , the sealing surface of the seal and the connecting seat should be ground and reassembled. Welding, bonding and other methods can be used to repair the parts with large corrosion damage; if the sealing ring connection surface is corroded, it can be repaired by grinding , bonding and other methods. If it cannot be repaired, the sealing ring should be replaced.
