The Importance of Maintenance and Repair on Valves
For a long time, most domestic industries used new valves to replace the old, and they sold or abandoned the old valves as garbage. As for some be replaced high-pressure valves, high-temperature valves and large valves, the companies wanted to repair it, but they had no idea about it. Most of them stayed in the manual repair level. In a manner of speaking, wasted and available benefit is enormous in Chinese valve repairing industry. Recent years, with each department gradually starting to make the economic calculation individually, people from manager to maintainer are realizing the importance to repair valves, because the money that they can save in this way is very considerable. However, repairing valves in here is not only the simple repair, but includes taking right repair methods and using superior lapping repair equipment.
Owing to the lack of equipment and the concepts of repairing and overhauling to valves, in our country only nuclear power stations can basically finished the job to overhaul all the valves during the overhaul downtime. To repair valves after it broke down is a kind of repairing method without maintainability. It’s bad to the safe operation of the complete equipment and the useful life of the valves. The potential risk to make the emergency shut down accidents is so great that can cause massive loss.
If the valve is under a position that it get repaired but without good care, once it let out the damage tends to be very serious. It can not only increase the difficulty to repair, but often lose the possibility and value to repair the valve. Hence, for the organized and well managed valve repairing works, not just the related workers need to have relevant consciousness, the more important thing is to prevent and take maintain measures which is to check the valve in regularly. The key to repair valves in preventive is to repair the valve at once when you first find the leakage of it. If not, the high cost of the maintenance will be created, because even if the super-tiny damage appear in the seal surface the circulating medium can make widespread damage in seal surface within a short time.
