摘要(Abstract)：
作者进行了三种典型结构的安全阀阀前压力及调节圈位置对安全阀排量系数影响的试验,本文对试验结果进行了分析和讨论,得出了一些对安全阀设计和使用有指导意义的结论。
The effect of ring piston and upstream pressure on the discharge coefficient was tested on three typical safety valves, and the experimental results were analysed and discussed in this paper. Meanful results which might guide the design and use of the safety valves have been drawed.
