PROBLEM TO BE SOLVED: To provide an inspection method and inspection device of an annular nozzle which can facilitate inspection of the annular nozzle and can reduce man-hours and cost for the inspection. SOLUTION: The inspection device 1 of the annular nozzle inspects the annular nozzle 5, which includes a discharge port 50 arranged on a circumference of a circle, and a flow channel 51 formed inside and leading to the discharge port 50. The inspection device 1 of the annular nozzle includes an inspection tool 2, an air supply device 3, and a spherical body 4 for inspection. The inspection tool 2 includes a supply passage 24 communicating to an inflow port 52 of the flow channel 51. The air supply device 3 supplies air to the supply passage 24 and the discharged air is discharged from the discharge port 50 so as to collide with the spherical body 4 for inspection. The spherical body 4 for inspection is floated in a floating state depending on a discharge state of the discharged air. COPYRIGHT: (C)2013,JPO&INPIT |
