比例阀在冲击式水轮机调速器中的应用

摘要

This paper expounds the working principle of proportional valve, and is aimed at two kinds of commonly used proportional valve, namely proportional flow control valve and a proportional servo valve are introduced, and further makes comparison on the applications of the proportional flow control valve and a proportional servo valve in large impact type hydraulic turbine governor.%本文阐述了比例阀的工作原理,并针对两种常用的比例阀,即比例方向流量控制阀和比例伺服阀的特点进行了介绍,进一步对比例方向流量控制阀和比例伺服阀在大型冲击式水轮机调速器的应用情况作了比较.
