THROWN DEVICE OF DRY CHEMICAL FIRE SUPPRESSION Russian patent published in 2013 - IPC A62C17/00 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to fire-fighting equipment, namely to a device thrown under the influence of the pulse of barrelled launcher. The thrown device of dry chemical fire suppression comprises a cylindrical housing, a streamlined head part, dry chemical powder, the dry chemical powder fluffing agent, and means of its displacement. The dry chemical powder fluffing agent is a gas generator which is mounted with the ability of its replacement at the upper part of the housing. The gas generator is provided at the lower part with the aerator connected with it gasdynamically, and the upper part - with the electric trigger element. The lateral surface of the aerator is equipped with holes that are blocked with opening elements. One electrical wire of the electric trigger element is connected to the housing of the device. The second one is electrically insulated from the housing and connected to the metal cylindrical element of solid section, which is mounted coaxially to the gas generator. The cylindrical element protrudes from the upper part of the housing, and the streamlined head part of the device is releasably connected to the housing and is made meshed. The lower part of the housing is equipped with a neck that is blocked by the breakable membrane. The membrane is pressed against the neck by the swivel nut which is connected to the nozzle extension. The nozzle extension is placed in the interior of the head part of the device and is made in the form of a hollow cylinder with a longitudinal through slots and a central hole.

EFFECT: increased efficiency.
