Regular inspection and leakage detection of conventional electric ball valves

Regular inspections are the core of any preventive maintenance plan, and electric ball valves should be inspected at high pressure or Ji end temperature on a weekly or monthly basis, while electric ball valves that are not too tight should be inspected every six months or annually. Search for cracks and other faults in the housing of the electric ball valve, and inspect the sealing nuts and other hardware to ensure everything is tight. If possible, rotate the electric ball valve to ensure that it has not been grabbed from mineral or rust deposits.

Leakage detection should be another part of the routine routine inspection program for electric ball valves. For electric ball valves that handle water, acid, and other liquids, leaks are usually more easily detected. Especially for explosion-proof electric ball valves, even if there is no visible humidity or leakage fault, attention should be paid to the signs of mineral accumulation or corrosion on the outer shell of the electric ball valve after one or two weeks of use.
Electric ball valves for handling compressed air, refrigerant, and other gases can be checked with a simple soap water mixture. Spray this mixture onto the electric ball valve and observe the formation of bubbles. Another option is to use an electronic leak detector. These devices are more efficient than the soap water method for two reasons: they reduce the risk of errors and can detect small leaks.
