FIRE-EXTINGUISHING SYSTEM Russian patent published in 2012 - IPC A62C2/00 

FIELD: fire-extinguishing equipment.

SUBSTANCE: invention relates to fire-extinguishing system, in which gas is directed into compartment under pressure of adjusted level. Fire-extinguishing system contains reservoir for supply of fire-extinguishing gas into protected compartment, regulator of fire-extinguishing system control, pipe with a valve. Reservoir is connected with supply pipe, which leads to said compartment. Regulator is made with possibility of control of valve for changing pressure in supply pipe, extending from reservoir. Regulator is made with possibility first, during some period of time, to supply high pressure into said pipe, then, when said period expires, to switch to lower pressure, for the time of mode of supporting fire-safe environment. Regulator is made with possibility of obtaining feedback, by, at least, one of the parameters: pressure and temperature, connected with compartment, and selectively regulate pressure by data of said feedback.

EFFECT: invention has a number of advantages, with valve being capable of accurate regulation of amount of gas, supplied to protected zone.
