Description of the processing procedure for the inner leakage of the vacuum ball valve

Vacuum ball valve internal leakage treatment program

1 First check the limit of the valve to see if the inner leakage of the valve can be solved by adjusting the limit.

2 First, inject the amount of grease to see if it can stop leakage. At this time, the injection speed should be slow. At the same time, observe the change of the pointer of the grease gun outlet pressure gauge to determine the internal leakage of the valve.

3 If the leak cannot be stopped, it may be that the sealant that was injected early hardened or the seal surface was damaged to cause endoleak. It is recommended to inject the valve cleaning fluid at this time to clean the sealing surface of the valve and the valve seat. Generally, it is immersed for half an hour. If it can be soaked for several hours or even a few days, the solidified materials are all dissolved before further processing. The active valve can be switched on and off several times during this process.

4 Re-inject the grease, intermittently open and close the valve, and discharge the impurities out of the rear cavity and sealing surface of the valve seat.

5 Check in the full position. If there is still leakage, inject the reinforced sealant and open the valve chamber for venting. This can create a large pressure difference and help seal. In general, by injecting the reinforced sealant The internal leak can be eliminated.

6 If there is still an internal leak, repair or replace the valve.
