What Are The Sealing Performance And Corrosion Resistance Of Large Fluorine-lined Ball Valves?
Lined Butterfly Valve is a valve product with excellent sealing performance and corrosion resistance. Fluorine-lined ball valves are lined with fluoroplastic materials on the surface of the ball. Common types include polytetrafluoroethylene (PTFE) fluorine-lined ball valves and fluororubber (FEP) fluorine-lined ball valves. Their sealing performance and corrosion resistance are very good.
1. Fluorine-lined ball valves have excellent sealing performance. The sealing mechanism of fluorine-lined ball valves uses polytetrafluoroethylene (PTFE) material. PTFE is a material with good sealing performance, low friction coefficient, excellent chemical corrosion resistance and good anti-aging performance. The fluorine-lined material forms a reliable seal between the ball and the sealing surface, and due to the good elastic recovery performance of the PTFE material, the fluorine-lined ball valve can maintain good sealing performance under different pressures to ensure that the medium will not leak. In addition, the fluorine-lined ball valve also has fireproof, anti-static and explosion-proof characteristics, ensuring the safe operation of the valve.
2. Fluorine-lined ball valves have excellent corrosion resistance. The surface of the fluorine-lined ball valve is lined with fluoroplastic material, which has strong corrosion resistance and can resist the erosion of various strong acids, strong alkalis, organic solvents and oxidants, and is suitable for a wide range of corrosive media. PTFE material has extremely low surface energy, which can effectively resist the adhesion of sediments, reduce the adhesion and scaling of the medium, and ensure the smoothness of the fluid. At the same time, PTFE material has good wear resistance, can maintain its corrosion resistance during long-term operation and frequent operation, and extend the service life of the valve.
3. Fluorine-lined ball valves also have good temperature resistance and impact resistance. PTFE material has a high melting point and thermal stability, and can maintain its performance unchanged at higher temperatures. Fluorine-lined ball valves can withstand media in the temperature range from -180℃ to 260℃, and are suitable for use in various high and low temperature conditions. At the same time, PTFE material also has good impact resistance, is not easily affected by external shocks and vibrations, and can ensure the stability and reliability of the valve.
In general, large fluorine-lined ball valves have excellent sealing performance and corrosion resistance. The PTFE material used has good sealing performance and corrosion resistance, which can effectively prevent medium leakage and corrosion damage of valves, ensuring the safe operation of the pipeline system. In addition, the fluorine-lined ball valve also has excellent temperature resistance and impact resistance, and can adapt to the requirements of different working conditions. Therefore, the large fluorine-lined ball valve is a very reliable and safe valve product, which is widely used in engineering projects in the petroleum, chemical, metallurgy, electric power, pharmaceutical and other industries.
