NOZZLE WITH NOISE ABSORPTION FUNCTION FOR GAS FIRE EXTINGUISHING MEANS AND METHOD OF STORAGE AND ASSEMBLY THEREOF Russian patent published in 2020 - IPC A62C31/02 

FIELD: fire-fighting equipment.

SUBSTANCE: group of inventions relates to a nozzle with noise suppression function for a gas fire extinguishing agent and to its storage and assembly method. Nozzle with noise suppression function for gas extinguishing means comprises noise suppression means, wherein nozzle is installed in gas fire extinguishing means, using fire extinguishing gas, by means of connection with pipeline, providing supply of fire extinguishing gas, for fire-extinguishing gas outlet into fire extinguishing zone, wherein said noise suppression means include a nozzle main body forming a connection portion for connection to said pipeline, a disc-shaped diaphragm forming an opening, a fire-extinguishing gas passage, and arranged in said nozzle main body, and a noise suppression element formed from blocks made of a porous material capable of passing a fire extinguishing gas and arranged on the outlet side of the diaphragm for discharging the fire extinguishing gas, wherein said disc diaphragm is detachably mounted in nozzle main body through hole in said connecting part of nozzle main body, connected to said pipeline. Disclosed also is a method of storing and assembling an atomiser with noise suppression function for a gas fire extinguishing means.

EFFECT: technical result is creation of nozzle with noise suppression function for gas fire extinguishing means and method of nozzle storage and assembly, which eliminate problems of storage space limitation and increase in cost, due to nozzle, convenient for storage as storage margin, taking into account the problem of said traditional nozzles for gas fire extinguishing means, in particular nozzles of fire extinguishing means with noise suppression function.
