トノズル装置。[Claims for Utility Model Registration] (1) A hollow cylindrical body in which a hollow chamber is formed has openings at both ends and sides on the central axis that communicate the outside with the hollow chamber, and A high-pressure water supply socket is connected to the opening at one end, and an abrasive grain supply pipe is connected to the opening at the side, so that the high-pressure water and the abrasive grains are mixed in the hollow chamber, and the other parts on the central axis are mixed. In an abrasive nozzle device that ejects a mixed jet from a focusing tube connected to an opening at the end, abrasive grain supply pipes are provided at multiple positions in the circumferential direction symmetrical to the central axis, and are connected to a hollow chamber and a focusing tube. An abrasive jet nozzle device characterized in that the casing tube is formed with a continuously converging tapered guide surface. (2) Utility model registration claim No. 1 characterized in that the abrasive grain supply pipes are provided at three locations in the circumferential direction.
The abrasive jet nozzle device described in (1). (3) At least the part of the hollow cylindrical body including the guide surface and the focusing tube are detachable from other parts of the hollow cylindrical body while remaining integral, and the central axis is automatically aligned with respect to the other parts. An abrasive jet nozzle device according to claim (1) of the utility model registration, characterized in that the abrasive jet nozzle device can be assembled together.
