摘　　要：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。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.
