| 摘要 |
控制阀是化工装置自动控制中重要的设备，其是否控制正确与否是关乎化工装置长周期运行的保障。本文介绍了控制阀的事故状态，控制阀调试的重要性，调试要点包括定位器信号中断、电磁阀动作、气锁阀联锁设定值更改、定位器误差死区调试、机械限位未安装到位、阀门检修后手轮机构测试，并且提出了出现问题后的处理措施，为同类故障的检查、分析提供思路，提出了预见性发现故障重要性。

| Abstract |
Control valve is an important equipment in the automatic control of chemical equipment. Whether its control is correct is the guarantee of the long-cycle operation of chemical equipment. This paper introduces the state of control valve accident, the importance of control valve debugging, debugging points including positionator signal interruption, solenoid valve action, air lock valve interlocking setting change, positionator error dead zone debugging, mechanical limit not installed in place, valve wheel mechanism test, and after the problem treatment measures, provide ideas for the inspection and analysis of similar faults, put forward the importance of foresight fault discovery.
