The packing is directly related to whether the
Ball Valve leaks when it is switched. If the packing fails and causes leakage, the Ball Valve will also fail, especially the Ball Valve of the urea pipeline, because its temperature is relatively high, the corrosion is relatively serious, and the packing is easy to age. Strengthening maintenance can extend the life of the packing.
When the Ball Valve leaves the factory, due to factors such as temperature, it may leak out. At this time, the nuts on both sides of the packing gland should be tightened in time. As long as there is no leakage, tighten it again in the future. Do not tighten it all at once to avoid the packing losing elasticity and sealing performance.
Some Ball Valve packings are filled with molybdenum dioxide lubricating paste. After several months of use, the corresponding lubricating grease should be added in time. When it is found that the packing needs to be supplemented, the corresponding packing should be added in time to ensure the sealing performance.
During the switching process of the Ball Valve, the original lubricating grease will continue to be lost, and coupled with the influence of temperature, corrosion, etc., the lubricating oil will continue to dry up. Therefore, the transmission parts of the Ball Valve should be checked regularly, and if any lubricant is found, it should be replenished in time to prevent increased wear due to lack of lubricant, resulting in malfunctions such as inflexible transmission or jamming.
