摘要： Low-pressure fire-extinguishing liquid is converted into mist. A fire-extinguishing spray nozzle (10) comprises a main body (30) and an obstacle (36). The main body (30) has a port (40) for radially injecting the fire-extinguishing liquid. The obstacle (36) is arranged within a radial injection region (102) of the fire-extinguishing liquid radially injected from the port (40). The obstacle (36) has an outer peripheral surface formed in the shape of a truncated-conical inclined surface (62). This enables the fire-extinguishing liquid (70) radially injected from the port (40) and passing around the obstacle (36) to collide with the fire-extinguishing liquid (72) radially injected from the port (40) and reflected from the inclined surface (62) so as to produce mist (74) of fire-extinguishing liquid. When producing the mist (74) by such an action, the fire-extinguishing liquid radially injected from the port (40) may have a low pressure. As a result, it is possible to provide a fire-extinguishing spray nozzle (10) which converts the low-pressure fire-extinguishing liquid into mist.

摘要： Low-pressure fire-extinguishing liquid is converted into mist. A fire-extinguishing spray nozzle (10) comprises a main body (30) and an obstacle (36). The main body (30) has a port (40) for radially injecting the fire-extinguishing liquid. The obstacle (36) has an opposing surface (60) and is opposite to the port (40). The opposing surface (60) is arranged within a radial-injection region (102) of the fire-extinguishing liquid radially injected from the port (40). One part of the fire-extinguishing liquid radially injected from the port (40) collides with the opposing surface (60) and is reflected therefrom. The other part of the fire-extinguishing liquid radially injected from the port (40) passes around the opposing surface (60). The one part of the fire-extinguishing liquid is reflected from the opposing surface (60) and the other part passes around the opposing surface (60). In consequence, the fire-extinguishing liquid (72) reflected from the opposing surface (60) collides with the fire-extinguishing liquid (70) passing around the supposing surface (60). The collision between the fire-extinguishing liquids produces mist (74).
