对汽轮给水泵速关阀的关闭特性进行理论建模和仿真计算研究，获得了工作水背压、阻尼系数及非线性因素对速关时间的影响。实际应用中，应避免工作水背压的提高。
對汽輪給水泵速關閥的關閉特性進行理論建模和倣真計算研究，穫得瞭工作水揹壓、阻尼繫數及非線性因素對速關時間的影響。實際應用中，應避免工作水揹壓的提高。
대기륜급수빙속관벌적관폐특성진행이론건모화방진계산연구，획득료공작수배압、조니계수급비선성인소대속관시간적영향。실제응용중，응피면공작수배압적제고。
The shut-down characteristics of quick closing valve of feed pump turbine are studied by the theoretical model and simulation. The influences of working water back pressure, damping coefficients and nonlinear factor on quick closing time are obtained. The back pressure of working water should not be increased in actual application.
