摘　　要：介绍了影响汽轮机高压调节汽阀无法开启的主要因素,结合某电厂因节流孔堵塞,造成安全油压无法建立导致的高压调节汽阀无法开启的处理过程,综合分析了各因素导致高压调节汽阀无法开启故障的排除方法,为火电机组汽轮机检修提出了相关指导方法。The main factors affecting the failure that the high-pressure governing valve of steam turbines cannot be opened are introduced.Based on the treatment process that the high-pressure governing valve failed to be opened because the safety oil pressure could not be established due to the blockage of the throttle hole in a power plant,the troubleshooting methods of the failure that the high-pressure governing valve could not be opened due to various factors are analyzed comprehensively,and the relevant guiding methods are proposed for the steam turbines'maintenance of thermal power units.
