Regulating valve of steam turbine and steam turbine

The utility model provides a regulating valve of a steam turbine and the steam turbine. The adjusting valve of the steam turbine comprises a shaft rod assembly, a valve rod assembly and a connecting shaft, the shaft rod assembly comprises a valve rod and a connecting shaft, and the connecting shaft sleeves the extending-in end of the valve rod; the connecting frame and the shaft rod assembly are arranged in the connecting frame in a penetrating manner; and the positioning structure is arranged between the shaft rod assembly and the connecting frame. The problem that in the prior art, a valve rod vibrates due to the fact that a gap is too large in the connecting position of the shaft rod assembly is solved. 本实用新型提供了一种汽轮机的调门及汽轮机。其中，汽轮机的调门包括：轴杆组件，轴杆组件包括阀杆和连接轴，连接轴套设在阀杆的伸入端；连接架，轴杆组件穿设在连接架内；定位结构，定位结构设置在轴杆组件与连接架之间。本实用新型解决了现有技术中由于轴杆组件连接处存在间隙过大而导致阀杆震动的问题。
