Heated steam supply passage 3 as a fluid supply passage
Is provided with an on-off valve 23 and a steam pressure reducing valve 25. The pressure reducing valve 25 is configured as shown in FIG.
The inlet 50 and the outlet 51 can be cut off by a valve 54. The diaphragm 52, which receives the pressure of the outlet 51 on the lower surface by a communication hole 53 with the outlet 51, is pulled upward by a coil spring 56 of a tensile action via a spring receiver 55. It is the one that is energized. Therefore, the pressure on the outlet 51 side is
When the pressure falls below the pressure corresponding to the tensile load of the coil spring 56, the diaphragm 52 is displaced downward, and at the same time, the valve element 54 is opened. When the pressure is restored to the pressure corresponding to the pressure, the diaphragm 52 is displaced upward and returns to the original position. At the same time, the supply of steam is stopped by closing the valve body 54. The tensile load of the coil spring 56 can be adjusted by moving the connection shaft 58 up and down by the electric motor 57. In the present embodiment, an example in which a self-acting pressure reducing valve as shown in FIG. 2 is used as the pressure reducing valve 25 has been described, but a conventionally known pressure control valve or the like may be used.
