摘要
本文对二级节流的刚度特性和气蚀特性进行了理论分析 ,对以水作为工作介质时其流量压力特性进行了实验研究 ,并将其与一级节流进行了比较。实验结果表明这种节流形式比相同形状的一级节流具有更强的抗气蚀性能。最后 。
This paper analyses the rigidity and cavitation characteristics of two-step throttle theoretically. Experimental research on its flow-pressure characteristics is carried out using raw water as working media and comparisons with one-step one are made. Test results show that this kind of throttle has stronger anti-cavitation ability than the one-step one of the same shape. Finally, its applications in water hydraulic valves are introduced.
