摘　　要：确立汽轮机调节阀开关时间的合格标准十分必要。介绍了影响汽轮机调节阀正常开关时间的因素,讨论了调节阀正常关闭时间与汽轮机转速飞升的定量关系,给出了合理确定汽轮机调节阀开关时间标准的方法,结合当前实际情况,确定了汽轮机调节阀开关时间的合格标准。It is quite necessary to determine approval standards for switching time of steam turbine steam tur- bine governing valve. The paper introduces factors that influence normal switching time of steam turbine gov- erning valve and discusses quantitative relationship between normal closing time of governing valve and rock- eting rotation speed of steam turbine. Furthermore, the paper gives way to determine standards for switching time of steam turbine governing valve and decides approval standards for switching time of steam turbine gov- erning valve.
