摘要:通过采用变频调节阀,配合PLC的软件编程,能够使甲醇精馏工艺控制系统的调节阀在一个高水平状态下运
行。变频调节阀是采用变频器主回路的电动调节阀,并通过改变节流方式来控制流量,所以它既是一种有效的调节手段,
同时又是一个节流节能、降低环境污染的部件,很值得在相关企业推广使用。

Abstract: The p roblem of the regulation valve is a challenge to the enterp rise which regards the quality and p rofit as its life.
So, how to select and install the regulation valve will be a p roject in the chemical p lant. It discusses the new control system which
uses the inverter dynamo2electric valve and PLC software in order to keep the regulation valve running in a high level state. The in2
verter dynamo2electric valve adop ts the main circuit of an inverter and changes the liquid flow. Therefore, it is an effective method
and can be widely used in the chemical factory with its energy2saving and pollution2cutting parts.
