SPRINKLER FIRE-EXTINGUISHING SYSTEM Russian patent published in 2013 - IPC A62C31/02 

FIELD: fire-fighting facilities.

SUBSTANCE: invention relates to fire-fighting equipment. The sprinkler fire-extinguishing system consists of a network of main and distribution pipelines, water-supply source, two automatic water feeders. The water-supply source is a tank with water and a system of water intake with a filter and a pump. The sprinkler housing is made in the form of a cylindrical sleeve with windows on its lateral surface. On the end of the cylindrical sleeve facing the spraying device side a partition of made. The spraying device is made in the form of a socket which is formed by a part of a spherical surface with the thickness "s". The socket is attached to the end surface of the sleeve by means of spokes which are fixed in the threaded sleeve. On the other threaded end of the sleeve the pipe fitting is axially mounted for supply of the fire-extinguishing agent. The pipe fitting is fixed on the sleeve with a lock nut. On the end of the pipe fitting, which faces the spraying device a conical groove is made. The spherical segment enters into the groove, blocking by the valve. The glass bulb with its one end rests on the end of the segment, and with the other - in an elastic insert. The insert is located in the center of the partition, in which the openings are provided for the passage of the fire-extinguishing agent towards the inner surface of the socket.

EFFECT: increased efficiency of fire-extinguishing is achieved due to the introduction of high-speed elements in the overall circuit of automatic fire-extinguishing system.
