FIRE-EXTINGUISHING SPRAY NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a fire-extinguishing spray nozzle capable of appropriately changing the atomizing performance by a simple and inexpensive method. SOLUTION: The fire-extinguishing spray nozzle is composed of an orifice plate with a spout for spouting a liquid; a single or a plurality of control plates having a channel for applying the revolving power to the liquid and a revolving chamber for collecting the liquid from the channel; and a lid plate for composing the channel and the revolving chamber when required. These three kinds of plate members are layered on one another inside a nozzle head. COPYRIGHT: (C)2008,JPO&INPIT
