In the maintenance of the fluorine-lined globe valve, the correct disassembly is very important. Only the correct disassembly can play its role to ensure the valve's role in production. So what should be paid attention to during the disassembly and assembly process? Let us find out with the manufacturer. The maximum flow volume of the electric cut-off ball valve: Due to its streamlined layman and full right-angle rotation control, the maximum volume is particularly high, the flow capacity is particularly large, and the flow resistance is small, so a smaller and more economical valve size can be used . The superior sealing performance of the metal seat of the electric shut-off valve: The V-type valve adopts a movable metal seat, which has a self-service compensation function, and has superior sealing performance and long service life. The pneumatic knife gate valve is a right-angle rotary regulating valve, which is used in conjunction with a valve positioner.
1. When disassembling the flange ball valve, the bolt connection nuts on the flange should be fixed first, then all the movable nuts should be slightly tightened, and finally fixed firmly. If the individual nuts of the students are forcibly fixed first, and then fixed and other nuts are needed, the uneven lining between the flange surfaces will cause the cushion surface to be damaged or ruptured, resulting in leakage of the media information out of the valve flanges in our country. 2. If data cleaning is performed on the valve enterprise, the solvent system used must not conflict with the parts to be cleaned, and not corrode. If it is a special ball valve for a gas company, it can be cleaned in time with gasoline products. Reclaimed water cleaning technology can generally be used for the design of other related parts. When cleaning, it is necessary to thoroughly clean the remaining dust, oil and other attachments. For example, it cannot be cleaned with fair-faced concrete. It can be carried out with a cleaning agent such as alcohol without damaging the valve body and parts. Effective cleaning. After the cleaning work is completed, wait for the cleaning agent to evaporate thoroughly before proceeding with assembly. 3. Long-term storage in the open air will cause corrosion of some valve bodies and parts, which cannot meet normal life use. When the ball valve is stored, it should be rainproof, waterproof, and moisture-proof, and the flange cover should be tightly covered. Valves stored for more than 12 months should be re-analyzed and tested during use to ensure relatively stable safety performance. 4. If you find that there are subtle leaks in different packings during the study, use and management, you can tighten the stem nut slightly by yourself until it leaks or stops developing, but it is inevitable to continue tightening. 5. Generally, soft-sealed ball valves use tetrafluoroethylene as the material that affects the sealing structure, and the sealing surface of hard-sealed ball valves is made of metal surfacing. If it is necessary to thoroughly clean the inside of the pipeline ball valve, care must be taken to prevent damage to the sealing ring and leakage during disassembly.
