Key points of daily maintenance of self sealing pneumatic ball valve
During maintenance, if a slight air leakage is found on the cover and capsule of the self sealing pneumatic ball valve, it is generally not processed, or the pneumatic ball valve is vented and then inflated, which can generally eliminate the air leakage. The pneumatic ball valve with repeated slight air leakage and serious air leakage shall be disassembled for inspection. If necessary, replace the wrong parts or replace the whole valve.
In application, the contact part between the capsule and the upper and lower seats will produce relative sliding friction, and the surface of the capsule will be worn, which will cause serious wear to the capsule cord layer, especially the lateral swing of the larger bogie, and the wear of the contact part between the capsule of the pneumatic ball valve and the top cover or the lower edge. During inspection, attention should be paid to check whether the capsule surface is allowed to have local slight scratches and wear, However, if the line layer is worn, a new product should be replaced.
