FIRE SPRINKLER SYSTEM Russian patent published in 2011 - IPC A62C35/00 A62C31/02 

FIELD: fire-fighting means.

SUBSTANCE: higher fire extinguishing effectiveness ensured by introducing high-speed elements in a common automatic circuit, in a fire sprinkler system consisting of a water source, a main and distributive piping network with sprinkler heads, there is an auxiliary a main water feeder with a filter dipped in a source connected to the main pipeline, and a charge circuit parallel to a main water feeder line and including an auxiliary water feeder pipeline, and an auxiliary automatic water feeder. The control signal system comprises a check alarm valve. The main pipeline is connected to a distributive piping network wherein sprinkler heads are integrated. Each head represents a union nipple with a through hole and a threaded portion extending into an end valve portion. The union by an axial-symmetric supporting arm consisting of two vertical volume stiffening ribs and two inclined prismatic ribs rigidly connected thereto is rigidly connected with a linear bushing with a female thread coupled with a clamp bolt which presses a glass bottle to an isolating disk valve. On the other side, an atomiser comprising a gapped-petal socket is fastened to the bushing perpendicularly to its axes. The axial-symmetric disk valve is separated by a packing on the side of the union nipple opposed to the threaded portion. The glass bottle is an expansion lock actuated by temperature rise.

EFFECT: more effective fire extinguishing.
