FIELD: fire extinguishing devices.
SUBSTANCE: invention relates to fire extinguishing devices and namely to fire nozzles. The device has a rack with a flange, a rotary body, a rotary barrel connected by hinged joints with sealing collars, and an ejection nozzle installed on the barrel connected through a vacuum pipeline to the frother tank. The vacuum pipeline is connected to an additional branch. One side of the branch is connected with the rack with the flange, whereas the other side is located along its central axis and pivotally connected to a movable branch mounted on a rotary body connected by a corrugated flexible tube with an ejector adapter. In contrast to existing fire nozzles, the proposed manual ejector fire nozzle has a vacuum pipeline built into the nozzle for supplying foaming agents. The proposed technical solutions allow the nozzle to freely move around its entire operating space, significantly reduce the length of the vacuum pipeline, increase the efficiency of ejection, and reduce the size of the device.
EFFECT: invention constitutes an ejector fire nozzle freely moving around its entire operating space with the reduced length of the vacuum pipeline and increased efficiency of ejection.
