FIRE-EXTINGUISHING SPRAY NOZZLE AND FIRE-EXTINGUISHING EQUIPMENT
Fire-extinguishing fluid at low pressure is nebulized. A fire-extinguishing spray nozzle (10) has a body (30) and an obstacle (36). The body (30) has an emission port (40) for the fire-extinguishing fluid. The obstacle (36) has a counter surface (60). The counter surface (60) faces the emission port (40). The counter surface (60) is arranged in an emission region (102) of the fire-extinguishing fluid emitted from the emission port (40). A part of the fluid emitted from the port (40) collides against the counter surface (60) and is reflected. Another part of the fluid emitted from the port (40) passes around the counter surface (60). Since a part of the fire-extinguishing fluid is reflected from the counter surface (60) and another part of the fluid passes around the surface (60), the fire-extinguishing fluid (72) reflected from the counter surface (60) collides against the fire-extinguishing fluid (70) passing around the counter surface (60). As parts of the fire-extinguishing fluid collide against each other, mist (74) is generated.
Fire-extinguishing fluid at low pressure is nebulized. A fire-extinguishing spray nozzle (10) has a body (30) and an obstacle (36). The body (30) has an emission port (40) for the fire-extinguishing fluid. The obstacle (36) is arranged in an emission region (102) of the fire-extinguishing fluid emitted from the emission port (40). An outer peripheral surface of the obstacle (36) is formed to be a truncated-cone-shaped slope (62). Thus, fire-extinguishing fluid (70) emitted from the emission port (40) and passing around the obstacle (36) and fire-extinguishing fluid (72) emitted from the port (40) and reflected from the slope (62) collide to produce mist (74) of the fire-extinguishing fluid. When the mist (74) is produced by such an action, pressure of the fluid emitted from the emission port (40) can be low. As a result, the fire-extinguishing nozzle (10) for making the low pressure fire-extinguishing fluid into the mist can be provided.
