| Zusammenfassung: | To provide a water screen formation device that forms a water screen at a high position by forming a water column to the high position by fire-fighting water jetted from a nozzle part.SOLUTION: In a water screen formation device 3 of the present invention, a nozzle part 30 has a first nozzle passage 32 that has an exhaust nozzle 31 formed at one end, and a second nozzle passage 33 that is connected to the other end of the first nozzle passage 32. The first nozzle passage 32 is formed into a cylindrical shape with a constant inside diameter, and the second nozzle passage 33 is formed into a tapered shape by gradually reducing an inside diameter toward a downstream side from an upstream side.SELECTED DRAWING: Figure 1
【課題】ノズル部から噴出させる消火水による水柱を高い位置まで形成し、高い位置で水膜を形成する水膜形成装置を提供すること。【解決手段】本発明の水膜形成装置３は、ノズル部３０は、噴出口３１を一端に形成する第１ノズル通路３２と、第１ノズル通路３２の他端に連接する第２ノズル通路３３とを有し、第１ノズル通路３２を内径が一定の筒状に形成し、第２ノズル通路３３を、上流から下流に向けて内径を漸次縮小させてテーパー状に形成したことを特徴とする。【選択図】 図１ |
