标准摘要
[中文适用范围]: IEC 60534 的这一部分定义了节流闭环控制应用中使用的控制阀的阶跃响应的测试和报告。控制阀由控制阀体、执行器的完整即用型组件组成,以及任何需要的附件。最可能的附件是阀门定位器。注:有关背景,请参阅技术报告 ANSI/ISA-TR75 25.02[6] 本标准的目的是定义如何在开环环境中测试、测量和报告控制阀响应特性。这些信息可以是用于过程控制应用,以确定控制阀对控制阀输入信号的响应程度和速度。本标准没有定义过程控制可接受的控制阀性能,也不限制任何应用的控制阀的选择。如果本标准用于评估或验收测试,双方可以同意记录这些要求的变化。使用定义的测试方法的信息特别适用于闭环反馈控制,但也可能对开环控制应用有一些应用。它不涉及开关控制服务中使用的阀门。本标准中规定的测试可能不足以测量所有应用所需的性能。并非所有控制阀应用都需要此测试。 [外文原描述]: It defines the testing and reporting of the step response of control valves that are used in throttling closed-loop control applications. A control valve consists of the complete, ready-to-use assembly of the control valve body, the actuator, and any required accessories. The most probable accessory is a valve positioner. It defines how to test, measure, and report control valve response characteristics in an open-loop environment. This information can be used for process control applications to determine how well and how fast the control valve responds to the control valve input signal. The contents of the corrigendum of June 2008 have been included in this copy.
