ATOMISER WITH FUNCTION OF NOISE SUPPRESSION FOR GAS FIRE EXTINGUISHING SYSTEM Russian patent published in 2016 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: invention objective is development of nozzle for gas fire extinguishing system, namely small-size nozzle, using of which noise level and reaction force acting on nozzle during release of fire-extinguishing gas are reduced. Said task is solved in nozzle 1 with noise suppression facilities for gas fire extinguishing system, enabling discharge of gas fire extinguishing to fire area, wherein noise suppression facilities contain modular silencing elements 4 made from gas-permeable porous material and arranged from outlet side holes 31. At that, one of end surfaces of noise suppression elements 4 is in contact with main body 2 and peripheral surface and second end surface of noise suppression element 4 is interconnected with atmosphere, except for section, which is in contact with circular element 6, used for attachment of noise suppression element 4 to main body 2 using bolts 5.

EFFECT: noise level and reaction force acting on the nozzle during release of fire-extinguishing gas are reduced.
