介绍了调节阀流量特性的软件修正的基本原理,给出了调节阀从固有的流量特性修正到期望特性的计算公式。通过编制软件实现后,能使同一台调节阀拥有多种流量特性,从而简化了阀芯的加工和在控制对象不同时均有良好的调节品质。
The basic principle of software correction of the flow characteristics of the control valve is introduced. The calculation formula of the control valve from the inherent flow characteristics modification to the desired characteristic is given. Through the preparation of software to achieve, with the same control valve can have a variety of flow characteristics, which simplifies the processing of the spool and not in the control of the object have a good adjustment quality.
