The electric control valve in the ⁷⁶Ge isotope production process is controlled by the PID module of the DCS (Distributed Control System) to regulate the internal pressure of the cascade pipeline. However, when the pressure of the process system fluctuates greatly, the existing control method of electric valve can not achieve the optimal control effect, which leads to the controlled process pressure exceeding the operating safety limit and has a serious adverse impact on the safe and stable operation of the process system. Aiming at the problem of weak control performance of electric valve under abnormal pressure, this paper put forward a control scheme to optimize DCS control configuration program of electric valve. Actual operation shows that the optimized control program avoids significant fluctuations in process pressure under abnormal conditions, effectively ensuring the safe and stable operation of the ⁷⁶Ge isotope production line.
