SPRINKLER SYSTEM Russian patent published in 2010 - IPC A62C31/00 

FIELD: fire fighting equipment.

SUBSTANCE: sprinkler system accommodates main line grid and distribution pipework consistently filled with a liquid fire extinguishing composition, sprinklers, a water supply source representing a water tank and a water intake system with a filter and a pump, and two automatic water feeders. A sprinkler case comprises a through-hole flow nipple with a threaded portion transformed in an end valve segment. The flow nipple is rigidly connected with a hollow cylinder bushing with a female thread for a clamp bolt which presses a glass bulb to a poppet valve. An atomiser in the form of a gapped petal socket is attached to the bushing from the other side. The isolating poppet valve is connected with an automatic response element of fixed indoor temperature rise comprising a glass bulb which is a thermal lock.

EFFECT: higher fire extinguishing effectiveness ensured by bringing into service of the high-speed elements in a common fire extinguishing circuit.
