SPRINKLER FIRE-EXTINGUISHING INSTALLATION Russian patent published in 2018 - IPC A62C31/02 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to firefighting equipment. This is achieved by the fact that in the sprinkler fire extinguishing installation, consisting of a water supply source, network of main and distribution pipelines with sprinkler heads, it additionally contains a main water feeder with a filter placed in the source, and connected to a main pipeline and a make-up system installed parallel to the main water feeder line and including an auxiliary water supply make-up pipeline and an auxiliary (automatic) water feeder, and the control and signaling system includes a control and signaling valve and a signaling device, for example in the form of a sound siren, wherein the main pipeline is connected to a network of distribution pipelines in which sprinkler heads are mounted, body of the sprinkler head is made in the form of a fitting with a through hole and a threaded part, with a sleeve with a filter screen fixed to it in the through-hole of the nozzle, threaded fitting by means of an axisymmetric bracket consisting of two vertical volume stiffeners and two inclined prismatic ribs rigidly connected to them, rigidly connected to a hollow cylindrical bush with an internal thread engaged with a clamping screw which, through an elastic gasket, urges the glass bulb against the poppet valve, glass bulb is supported by a valve through an elastic gasket fixed to the outer end face of the valve, which by means of a chain is connected to one of the volume stiffeners, and on the other hand to the sleeve, perpendicular to its axis, is fastened by means of screws a spraying device in the form of a socket with a central hole and petals located relative to each other with a gap.

EFFECT: technical result is increase in efficiency of fire extinguishing due to introduction of high-speed elements in general circuit of automatic fire extinguishing system.
