水压驱动控制棒是一种全新的核反应堆控制技术,直动电磁阀是其关键部件.电磁阀的性能直接影响控制棒水压驱动系统的稳定运行.运用ANSYS电磁场分析软件研究直动电磁阀阀头在不同输入电流的工况下温度场的特性.结果表明,当电流增大时,阀头温度升高; 阀头中心温度高于边缘温度,中心最高温度低于阀头破坏温度; 内壁温度高于外壁温度,其中内壁中心温度为最高壁温; 计算结果与实验数据的对比说明,该数值计算分析有较高的准确性.
A hydraulic drive control rod is a new control technology of nuclear reactor. The direct action solenoid valve is a key component of this technology. The performance of the direct action solenoid valve directly affects the stable operation of control rod hydraulic drive system. The temperature field of the head of the direct action solenoid valve with various currents was studied using the ANSYS software. The result shows that the temperature of the head of the solenoid valve increases as the current increasing. The temperature of the middle head is higher than that of the edge of the head and the highest temperature of the middle head is under the limiting temperature. The temperature of the inner wall of the head is higher than that of the exterior wall. The results calculated by ANSYS were verified with the experimental testing.
