摘　　要：由两个节流口组成的二级节流或防止或减轻水压阀汽蚀的有效结构形式。对以淡水作为工作介质的二级节流阀汽蚀性能进行的理论分析与实验研究表明Two-step throttle, which consists of two orifices, is an effective form to avoid or reduce cavitation damage. Theoretical and experimental researches are exected to investigate the anti-cavitation and wire-drawing characteristics of two-step throttle when using tap water as the working medium. From testing results, it can be concluded that two-step throttle has stronger anti-cavitation ability than single-step one.
