The stainless steel ball valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is used to make the structure easy to seal, and the valve seal of the ball valve can increase with the increase of the medium pressure. The change of the internal structure of the stainless steel ball valve makes it Its mechanical properties are better than ordinary gray cast iron, and other properties are not damaged.

1. The new parts of the stainless steel ball valve should be cleaned before assembly.

2. Each single ball valve part decomposed from the stainless steel ball valve can be cleaned by dipping. Metal parts with non-metallic parts left undecomposed can be scrubbed with a clean and fine silk cloth impregnated with cleaning agent. This prevents fibers from falling off and sticking to the part. When cleaning, all grease, dirt, glue, dust, etc. adhering to the wall must be removed.

3. Metal debris, fibers, grease (except those specified for use), dust, other impurities, foreign objects, etc. should not be allowed to contaminate, adhere or stay on the surface of the parts or enter the inner cavity during assembly of the stainless steel ball valve. The stem nut must be tightened again.

4. After the stainless steel ball valve is cleaned, it needs to be assembled after the cleaning agent on the wall to be washed has evaporated (it can be wiped with a silk cloth not soaked in the cleaning agent), but it should not be left for a long time, otherwise it will rust and be polluted by dust. Be careful not to lock it too tightly, usually lock it for another 1/4 turn to 1 turn, and the leakage will stop.
