SPRAYING NOZZLE FOR EXTINGUISHING FIRE, WHICH HAS A WATER SUPPLY HOLE CAPABLE OF EASILY CONVERTING FIRE-EXTINGUISHING WATER WHICH IS SUPPLIED FOR A WATER SPRAY INTO A VORTEX WITHOUT INCLUDING A VORTEX GENERATION VAN

摘要

PURPOSE: A spraying nozzle for extinguishing fire is provided to reduce the number of components without a necessity of a vortex generation van by forming vortex water supply holes which supply fire-extinguishing water in a tangential direction which borders on an inside diameter of a vortex chamber in a vortex member.;CONSTITUTION: A spraying nozzle for extinguishing fire which has a water supply hole includes an adapter (100), a body (200), and multiple nozzle tip parts (300). The adapter is combined with a water supply pipe. The body includes multiple tip holes (233) in which the multiple nozzle tip parts are formed in the bottom surface and is combined with the adapter through the upper surface. The nozzle tip part includes a vortex member and a nozzle tip (310). The vortex member is mounted on the tip hole and includes a vortex chamber and one or more vortex holes (375). The vortex water supply hole is formed on the outer side surface of the vortex chamber in order to supply fire-extinguishing water to the vortex chamber. The nozzle tip fixes the vortex member by being inserted into the tip hole after the vortex member is inserted into the tip hole and sprays supplied vortex supply water in the vortex member.;COPYRIGHT KIPO 2013
