摘要
过程控制中的各个环节对控制都有影响,而最终环节即调节阀对过程控制的影响最为直接和明显。详细讨论了调节阀的各个参数如流量特性、放大倍数、压力降、执行机构与定位器、供风压力、口径、摩擦对过程控制的影响,最后预测了调节阀的发展趋势。
Process control is under the influence of all parts of loop, but the most direct and apparent part is the final element i. e. control valve. The influence of various control valve parameters on the process control such as flow characteristics, gains, pressure drop, actuator, positioner, air power pressure, caliber and friction has been discussed in detail. In addition, developing trend of control valve is predicted.
