With the rapid development of modern industry, the noise becomes more and more loud. But there are people everywhere, especially in rural and industrial areas, which is a fatal chronic disease. Slowly. People also know that noise can damage people's bodies and even lead to death.
Therefore, noise pollution is one of the environmental pollution that must be enriched and ignored. The power and speed of instruments and equipment are increasing. The harm of vibration and noise is more and more prominent. Such vibration and noise not only pollute the environment and affect people's weaknesses, but also have a great impact on product ethics and operating accuracy. In addition, it can also shorten product life and seek emergency insurance.
Therefore, mastering the control technology of vibration and noise is an important subject for industrial development in various countries. One of the effective ways to eliminate vibration and noise is to increase vibration sources and isolate vibration transmission. At present, the widely used structural form is to use materials and skeleton materials (such as metal, fiber, engineering plastics, etc.) to eliminate vibration shock and absorb noise from vibration sources through functional disassembly or special viscoelastic high damping materials. Etc.). The functional disassembly of the electric butterfly valve has been widely used in aircraft, ships, automobiles, trains, construction projects, and vibration isolation of instruments and meters.
