PURPOSE:To increase rigidity, decrease flexural rate, and decrease opening of the horizontal coupling face in such a way that the outer ring on the steam outlet side of the half body of a nozzle diaphragm is joined witha clamping bolt, and the inner ring on the opposite side is joined with a stud bolt and a tapered pin. CONSTITUTION:A screw hole 20 is made at an outer ring 8 which is positioned on the steam outlet side of the half body 5b of a nozzle diaphragm, and a screw hole 21 is made opposite to the screw hole 20 at the outer ring of the half body 5a of the nozzle diaphragm, and they are joined with a clamping bolt 10. Besides, a screw hole 22 is made on the outer peripheral side of an inner ring 7 which is positioned on the opposite side to the steam outlet side of the half body 5b of the nozzle diaphragm, and on another hand, a recessed part 25 is made opposite to the screw hole 22 at the half body 5a of the nozzle diaphragm, a stud bolt 23 is screwed into the screw hole 22, a tapered pin 28 is inserted into a recessed part 25, and the inner ring is joined. |
