调节阀是化工自动控制系统的一个极为重要的装置,同时也是自动控制系统中一个主要的耗能单元。本文论证了对调节阀采用低S值运行以降低调节阀能耗的可能性;介绍了低S值运行的调节阀流量特性畸变规律;论述了调节阀的选择原则及低S值运行的试验结果。
The regulating valve is an extremely important device of the chemical automatic control system, and it is also a major energy-consuming unit in the automatic control system. This article demonstrates the possibility of using a low S value for the regulating valve to reduce the energy consumption of the regulating valve; introduces the distortion law of the flow characteristic of the regulating valve with a low S value; discusses the selection principle of the regulating valve and the test results of the low S value operation. .
