FLUID CIRCULATION RESTRAINING STRUCTURE, FLUID CIRCULATION RESTRAINING TOOL, AND FLUID DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fluid circulation restraining structure by which the flow of a fluid can be restrained as required at the time of the occurrence of a fire by avoiding influences caused by the flow of the fluid and the gravity to the utmost, a fluid circulation restraining tool, and a fluid device.

SOLUTION: The fluid circulation restraining structure is so constituted that a thermally expanding member 5 for restraining the flow of the fluid by being expanded by heating is arranged in a state not obstructing the flow in the vicinity of the flow of the fluid and the expansion of the thermally expanding member 5 is positively guided to the side in the direction restraining the flow by providing an expansion regulating member 10 for regulating the expansion direction of the thermally expanding member 5. The fluid circulation restraining tool is provided with the fluid circulation restraining structure and has a mounting means 9 fittable to the inner face of a fluid pipe P in which the fluid flows. The fluid device has the fluid circulation restraining structure provided to the flowing place of the fluid.
