FIRE EXTINGUISHING SYSTEM SPRINKLER Russian patent published in 2022 - IPC A62C37/08 

FIELD: fire protection.

SUBSTANCE: invention relates to devices used as part of fire extinguishing systems and designed to extinguish, localize or block a fire by spraying water or aqueous solutions. The sprinkler of the fire extinguishing system contains a hollow cylindrical housing with a side and end surface and made with an internal working chamber, nozzles made in the form of a through channel from the outer surface of the housing to the inner working chamber, the channel inlet is made from the side of the inner working chamber, and the channel outlet is made from the outside of the sprinkler housing. The cylindrical body is additionally made with an inclined surface formed from the side to the end surface, while a number of nozzles are made on the inclined surface along the circumference, made with the possibility of forming an external finely sprayed dynamic flow of extinguishing liquid, and nozzles are made on the end surface of the body, made with the possibility of forming an internal finely sprayed dynamic flow of extinguishing liquid, while from the outside the channels of each row of nozzles are made with a conical expansion to form a conical channel outlet, and on the side of the working chamber, the channels of each row of nozzles are made with a conical narrowing towards the channel, while the angle of the conical edge relative to the axis of the through channel is no less than 30 degrees and no more than 90 degrees, and the length of the truncated cone, measured perpendicular to the leading edge, is equal to or exceeds the length of the through channel.

EFFECT: use of the invention makes it possible to ensure the efficiency of the distribution of the flow of extinguishing liquid over the irrigation area, which accordingly makes it possible to increase the efficiency of fire extinguishing.
