气动调节阀是核电站广泛应用的重要设备之一，尤其是核岛中的阀门在核电站系统运行中起着重要的控制、调节作用。其运行的品质直接影响到机组的效率和安全。系统以CRIO为主体，辅以不同类型的传感器及接口搭建阀门诊断系统硬件平台。同时对采集到的数据自动分区，分析其非线性度、计算弹簧力、落座力、摩擦力等参数。在无需拆解阀门的条件下实现现场十几类气动阀门的性能诊断。%Pneumatic control valve is one of the important equipment plant is widely used, especially in the nuclear valves in nuclear power plants in the operation of the system plays an important role in controlling and regulating. Diagnosis system by CRIO as the main body, with different types of sensors and interface build valve diagnostic system hardware platform. For automatic partitioning the data collected at the same time, analyze its nonlinearity, calculate parameters such as spring force, take the force, friction force. Under the condition of without dismantling the valve to realize the performance of the field more than ten classes of pneumatic valve diagnosis.
