Referring to the drawings; The fire throwing sprinkler 2 is composed of a hollow spherical body 4, a fastening tube 6, a nozzle 8, a metal sphere (10). And a water supply device (not shown) for supplying fire fighting water to the fire fighting throwing sprinkler 2 is made by a conventional technique.

The hollow spherical body 4 is completely spherical and is not limited in size, thickness, or number of nozzles 8, but varies according to the injection capacity.

In addition, the hollow spherical body 4 is formed by selecting at least one of an elliptical shape, a garden shape, and a triangular pyramid shape. In addition, it is possible to change within the objective range of this invention by a design change.

The hollow sphere 4 may be thrown at a target point by a thrower (not shown) or thrown by a firefighter.

The fastening tube 6 is formed to protrude at any position of the hollow sphere 4 to be connected to the fire hose 12. The fastening pipe 6 is also coupled to the fire hose and screwed or assembled (not shown). In addition, the fastening pipe (6) is formed to protrude by forming a screw on the outer peripheral surface, it is also possible to be formed to protrude into the hollow spherical body 4 without protruding and to form a screw on the inner peripheral surface to be combined with the fire hose.

The nozzles 8 are assembled at regular intervals throughout the hollow sphere 4. The nozzle 8 is assembled by screwing or otherwise to allow disassembly and assembly to enable internal cleaning. Moreover, the nozzle 8 is formed so that the fire water to be sprayed may be diffused to a predetermined range and jetted to a predetermined distance.

The nozzle 8 forms a discharge port 14 inwardly of the hollow spherical body 4, and the discharge port 14 forms a metal ball seat surface 16 to be airtight with the metal ball 10. Make contact.

The metal sphere 10 is formed to a predetermined diameter, and a large number is filled in the hollow sphere (4). The metal sphere 10 is filled with a quantity capable of maintaining about a third of the level in the hollow sphere (4). The metal sphere 10 is formed to a diameter capable of hermetically contacting the metal sphere seat surface 16 of the nozzle 8.
