1. As long as the pressure before and after the ball valve is removed, the ball valve can be disassembled and differentiated.
2. In the process of differentiation and reinstallation of the ball valve, it is necessary to maintain the sealing parts, especially non-metal parts, such as O-rings and other parts using special things.
3. When the ball valve body is reinstalled, the bolts are tightened symmetrically, gradually and evenly.
4. The cleaning agent should be compatible with rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, gasoline can be used to clean the metal parts. Clean non-metal parts with pure water or alcohol.
5. The differentiated individual parts can be cleaned by dipping. Metal parts with undifferentiated non-metal parts can be scrubbed with clean, fine silk cloth impregnated with cleaning agent (to prevent the fibers from falling and sticking to the parts). When cleaning, the grease, dirt, glue, dust, etc. adhering to the wall must be removed.
6. The non-metal parts should be taken out of the cleaning agent immediately after cleaning, and should not be soaked for a long time.
7. After cleaning, you need to wait for the wall surface cleaning agent to be washed to volatilize (can be wiped with a silk cloth not soaked in the cleaning agent) for installation, but it must not be left for a long time, otherwise it will rust and be contaminated by dust.
8. New parts also need to be cleaned before installation.
9. During installation, it is not allowed to pollute, adhere to or stay on the surface of the parts or enter the inner cavity with metal chips, fibers, external dust, other impurities, and foreign objects that are used in the rules of grease.
