规则要求按顺时针方向旋转手轮。
Regulation is accomplished by rotating the handwheel clockwise.
不需要旋转手轮，直接从手轮末端拆卸固定螺栓。
Without turning the handwheel, remove the retaining bolt from the end of the handwheel.
如果操作装置的安装孔与阀门法兰孔没有对应上，就要把锁定螺栓退回，旋转手轮式的螺栓孔对准为止。
If the operator mounting holes do not line up with the valve flange holes, the stop screw (s) should be backed off and handwheel turned until holes are aligned.
