The disassembly and differentiation of the ball valve can be done only if the pressure is first removed both before and after the valve.
During the ball valve's differentiation and reinstallation process, it is crucial to pay close attention to the sealing components, particularly the non-metallic ones, such as O-rings. These parts should be handled delicately using specific tools to avoid any damage or alteration. Proper maintenance of these components ensures a secure and reliable seal, guaranteeing optimal valve performance.
When reassembling the ball valve body, it is important to tighten the bolts symmetrically, gradually, and evenly.
To ensure proper maintenance of ball valves, it's essential to use cleaning agents that are compatible with all the valve's components, including rubber, plastic, and metal parts. It's crucial to consider the compatibility of the cleaning agent with the operating medium, such as gas, to avoid corrosion and damage. When cleaning metal parts in gas valves, it's recommended to use gasoline (GB484-89) as the cleaning agent. On the other hand, non-metal parts can be cleaned with pure water or alcohol. It's important to note that using inappropriate cleaning agents can cause damage to the valve's components, leading to equipment malfunction and reduced longevity. Therefore, selecting the right cleaning agent is crucial for maintaining optimal valve performance and longevity.
When it comes to cleaning, there are different methods for different types of parts. If you have individual parts that are made of metal, they can be easily cleaned by dipping them in a cleaning solution. However, if you have metal parts that are attached to non-metal parts, such as screws or bolts, a different cleaning method is required. In this case, you should use a dry rotor pump clean silk cloth that has been soaked in a cleaning agent. This will ensure that no fibers from the cloth will come off and stick to the parts. It is crucial to remove any grease, dirt, glue, or dust that may be adhering to the surface of the parts. By following these cleaning instructions, you can ensure that your parts are thoroughly cleaned and ready for use.
To ensure proper cleaning of non-metal parts, it is important to remove them from the cleaning agent immediately after cleaning. Prolonged soaking in the cleaning solution should be avoided as it can cause damage to the parts. Hence, it is recommended to follow the manufacturer's instructions and take necessary precautions while cleaning non-metal parts.
Following the cleaning process, it is important to ensure that the cleaning solution on the wall surface is evaporated before installation (using a silk cloth to wipe, avoiding cleaning agent saturation). However, it is not recommended to leave it for an extended period as this may result in rust or dust buildup.
Cleaning new parts before installation is also necessary.
To achieve a smoother operation, it is advisable to utilize a smooth grease. This lubricating grease must be compatible with the metal materials of the ball valve, rubber components, plastic parts, and the media it operates with. For instance, when dealing with gas as the working medium, a specialized smooth grease such as the 221 variant may be employed. Application of a thin layer of smooth grease on the seal device groove, rubber seal surface, as well as the valve stem's sealing and conflict surfaces, is recommended.
During the installation process, it is imperative to prevent the introduction of metal chips, fibers, grease (beyond the specified guidelines), dust, impurities, or any other foreign objects onto the surface of the parts or into the cavity. It is crucial to maintain a clean and uncontaminated environment to ensure proper installation.
