0, and lubricating oil is supplied to each mechanism through a lubricating oil line 19. According to the present invention, an operating cylinder 23 is connected to the discharge side of the oil pump 16 by an operating cylinder oil line 21 via an orifice 22.

7, and by eliminating the pressure oil, it now occupies the lower fulcrum 26.
次に第5図に示す制御装置を用いて本発明の蒸気タービ

きだけ供給されるものである。The RCIC turbine 12 rotates as steam is supplied from the RCIC main steam line 8, and the RCIC turbine shaft 14 drives the RCI C water pump 13 and oil pump 1.
6 is driven. Oil is supplied from the oil pump 16 to a control oil line 20, an operating cylinder oil line 21, and a lubricating oil line 19. Note that oil supplied from the control oil line 20 flows into the oil cylinder 30 for controlling the steam control valve 11, and oil from the operation cylinder oil line 21 flows into the operation cylinder 23 in order to move the piston 24 in the operation cylinder 23. From the lubricating oil line 19, the lubricating oil is used as lubricating oil for the RCIC turbine 12. However, these oils are RCIC
It is supplied only when the turbine 12 is started and the oil pump 16 is driving.

とする。Since the RCIC turbine 12 is in a non-hydraulic state when stopped and immediately after starting, it is connected to the fulcrum 28 of the operating lever 29. Since the piston 24 of the operating cylinder 23 is pushed downward by the force of the attached spring 25, the lower fulcrum 2
6, therefore, the connected lever 29 is in the solid line position and the steam control valve 11 is in the half-open state 11a in FIG. This forcibly limits the rapid inflow of steam at startup. Note that after startup, the operating cylinder 23 is activated by the oil pump 16.
Hydraulic pressure is supplied to the operating cylinder 23, but since this operating cylinder 23 operates at a low oil pressure lower than the control oil pressure of the hot air control valve 11, it is assumed that it will not be affected by slight changes in the established control oil pressure.

トン24位置を移動させることにより支点28の位置の
移動をなめらかに行うものとする。Then, due to the low oil pressure supply, the piston 24 rises against the force of the q-bending spring 25 of the operating cylinder 23, and the fulcrum 28 moves to the upper fulcrum 27 in Fig. 3, and the lever 29 moves to the position indicated by the broken line in Fig. 5. As a result, the steam regulating valve 11 becomes fully open 110, but in the meantime, the established control oil for the steam regulating valve 11 is guided to the oil cylinder 30, and normal steam regulating valve control is started. At this time, as mentioned above, in order to time the switching from inflow steam flow rate restriction to normal steam control valve control at the time of startup of the RCIC turbine 12 by the operation cylinder 23, and also because the operation cylinder 23 operates at low oil pressure. An orifice 22 is provided in the operating cylinder supply hydraulic line 21, and the position of the fulcrum 28 is smoothly moved by adjusting the control oil and gradually moving the position of the piston 24 in the operating cylinder 23.

ことになる。この場合もオリフイス22によりなめらか
な支点28の移動が行われる。As mentioned above, during normal operation of the RCT C turbine 12 and pump 13, high oil pressure from the oil pump 16 is applied to the operating cylinder 2.
3, the screw latch 24 is pushed upward and performs normal steam control valve control with the upper fulcrum 27 and the fulcrum 28 at the top. Also,
When the RCI C turbine 12 and pump 13 stop due to unnecessary RCIC or other accidents, the oil pump 16
Since the oil pressure supplied from the lower fulcrum 26 disappears, the oil in the operating cylinder 23 drops and at the same time the screws 1 to 24 and the fulcrum 28 move downward, the force of the spring 25 prevails and the lower fulcrum 26 becomes the lower fulcrum 26, and the steam control valve 11 becomes half open. It will wait for the next RCIC activation. In this case as well, the orifice 22 allows the fulcrum 28 to move smoothly.

となる。By implementing the control method of the present invention, the turbine rotation speed 41 according to the present invention shown in FIG. The stabilization time of the turbine rotation speed can also be shortened. Regarding the displacement of the opening degree of the steam control valve 11, as shown in the conventional opening degree curve 36 in FIG.
A rapid change in opening is seen from to stable opening position '11b, and it takes some time for the control oil pressure to rise to i1f.
Steam hU Makoto valve] does not move, but the opening curve 38 according to the present invention improves these, and the operation of the fulcrum 28 by the operation cylinder 23 is performed almost simultaneously with the start-up, so '1. After i7 hours, the opening degree of the steam control valve 11 changes smoothly.

適用できる。In the above embodiment, the control of the RCIC turbine 12 of the reactor isolation cooling system in the nuclear reactor equipment was explained, but the control method according to the present invention uses only a DC power source that can be used for a short period of time, for example, for a start signal. It has a geothermal power generation system that it does not have, and a so-called steam source such as a turbine that can be used to supply backup power in the plant in case of an emergency. It can be applied to a steam turbine system that functions to supply oil by rotating an oil pump by driving itself.
