The paper introduces working principle of nuclear grade valve actuator＇ s torque control mechanism with combined disc spring. It analyses the mian parts of torque control mechanism detailedly, and also deduces the theoretic computational formula for designing the combined disc spring. Then it analyses the stess and transmogrification of the disc spring using the ANSYS. The method with finite element analysis and theoretic calculation can be introduced to the future design of disk spring that can be the same with the torque control mechanism of nuclear grade valve actuator, derivate
