Title:
FLUID INJECTION SYSTEM INTO PRESSURE VESSEL
Document Type and Number:
Japanese Patent JP2018031596
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid injection system into a pressure vessel capable of continuing a function of injecting water into the pressure vessel even in a no-power state.SOLUTION: The fluid injection system includes a water injection control mechanism 14. When the liquid level in a water storage tank 5 becomes low to increase the water head difference between pressure taps 12 and 13, the water injection control mechanism uses the variation in the water head difference as a driving force to close a pressure equalizing valve 9 and open a feed water valve 10, thereby feeding the fluid in a water pool 4 to the water storage tank 5 through a water feed flow channel 8. When the liquid level in the water storage tank 5 becomes high to decrease the water head difference between the pressure taps 12 and 13, the water injection control mechanism uses the variation in the water head difference as a driving force to close the feed water valve 10 and open the pressure equalizing valve 9, thereby feeding the fluid in the water storage tank 5 to a pressure vessel 1 through a water injection flow channel 7.SELECTED DRAWING: Figure 2
