The following points are explained about the maintenance skills of stainless steel ball valves:
① First check whether the pressure in the upstream and downstream pipelines of the stainless steel ball valve has been relieved, and only after confirmation can the disassembly and decomposition operation be carried out.
②To prevent damage to the sealing surface of stainless steel ball valve parts, especially for non-metallic parts, special tools should be used when taking O-rings.
③The flange bolts must be tightened symmetrically and evenly when installing the flange bolts.
④ The cleaning agent should be compatible with the rubber parts, intermetallic, plastic parts and working medium in the stainless steel ball valve.
⑤ The parts of the disassembled stainless steel ball valve can be cleaned by dipping, and the metal parts can be scrubbed with a clean silk cloth with cleaning agent.
⑥ After cleaning, the stainless steel ball valve needs to wait for the cleaning agent on the wall to be washed to volatilize before assembling, but it should not be left for a long time to avoid rust and pollution.
⑦The grease used should be compatible with the metal material, plastic parts, rubber parts and working medium of the stainless steel ball valve. The working medium is gas, such as special 221 grease can be used.
