Large-diameter triple-eccentric metal hard-seal butterfly valves are widely used in petroleum, chemical, metallurgy, electric power and other industrial fields. They have compact structure, excellent sealing performance, high temperature and high pressure resistance and strong corrosion resistance. They show unique advantages especially in large-diameter applications. . However, as the diameter of the valve increases, the force exerted by the fluid on the valve increases sharply, and the vibration problem caused by fluid-structure coupling becomes more obvious. This vibration not only affects the working stability of the valve, but may also cause structural fatigue damage and shorten the service life. CHNLGVF丨中國大乾洋貿 has studied the fluid-solid coupling vibration characteristics of large-diameter triple-eccentric metal hard-seal butterfly valves in response to these problems, and proposed a structural optimization strategy to provide theoretical basis and practical guidance for the development and manufacturing of high-quality butterfly valves.
