6. Usage: power plant equipment ( boiler suspension systems, transformer overload protection device) , the valve switches, high-voltage high-speed grounding tank, heat and clutch controller ( automobile and electrical machinery) , printing, turn the valve internal combustion engine, bridge damping device, heavy duty cranes, magnetic train, aerospace equipment, and so on.
6. Features: thermal expansion and contraction leading to repeated changes in preload, disc spring with super-high-temperature compensation, compensate for thermal expansion and contraction caused by repeated changes in preload, the preload remain stable, to prevent the bolt fatigue and gasket failure. Mechanical vibrations lead to changes in preload disc springs can effectively absorb the high-temperature mechanical vibration, to avoid mechanical vibrations caused by loose bolts, to ensure durable and reliable seal.
