MOBILE FIRE FIGHTING UNIT |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to fire fighting appliances, particularly, to knapsack fire extinguishers. Sprayer case of proposed unit is made up of central-bore union and outer-thread cylindrical shell rigidly coupled and aligned therewith. Cylindrical radial-flow fluid flow swirler to make nozzle jointed via inner-thread shell is jointed to and aligned with case bottom. Insert has at least three tangential inlet cylindrical bores. Shell makes nozzle integral part aligned with radial-flow swirler that has cylindrical throttle bore made in its face surface. Radial-flow swirler is arranged in case cylindrical chamber to form annular cylindrical chamber to feed fluid to radial-flow swirler tangential fluid inlets and communicated with outlet diffuser chamber. Said tangential fluid inlets represent channels arranged tangentially to cylindrical insert inner surface. ^ EFFECT: higher efficiency of fire fighting. ^ 2 dwg |
