Stainless steel flanged ball valve is a kind of general-purpose valve that is widely used in valve products. Because of frequent use, the amount of use is relatively large, and the loss is relatively large, so the production and sales volume is still very considerable. In order to make the service life of the stainless steel flanged ball valve as long as possible, people must maintain it scientifically and reasonably, which can not only improve the efficiency, but also reduce the maintenance time and save the replacement cost.
The following stainless steel flanged ball valve manufacturers introduce some maintenance to delay the service life of stainless steel ball valves:
Before use, we can clean the pipeline and valve body flow parts, mainly to prevent the residual iron filings and other debris from entering the valve body cavity. When the stainless steel ball valve is in the closed state, there will still be some residual medium in the body of the valve body, so it must bear a certain pressure. Before checking and repairing the stainless steel ball valve, the shut-off valve in front of the stainless steel ball valve must be closed first, and the opening must be checked. The repaired stainless steel ball valve fully releases the pressure inside the valve body. If it is an electric ball valve or a pneumatic ball valve, the power supply and air supply should be disconnected first. If PTFE is used as the sealing material, the sealing surface of the hard-sealed ball valve is made of metal surfacing. If you need to clean the stainless steel flanged ball valve in the pipeline, you should be careful to prevent damage to the sealing ring and leakage when disassembling.
