SPRINKLER FOR FIRE FIGHTING INSTALLATION Russian patent published in 2018 - IPC A62C31/02 B05B1/26 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting equipment. Sprinkler apparatus of fire extinguishing system consists of a water supply source, a network of main and distribution pipelines with sprinkler heads. Apparatus further comprises a main water feeder with a filter placed in the source and connected to the main pipeline, and a make-up system installed parallel to the main water supply line and including a make-up water supply pipeline and an auxiliary (automatic) water feeder. Control and signaling system includes a control and signaling valve and a signaling device, for example, in the form of a sound siren. Main pipeline is connected to a network of distribution pipelines where sprinkler sprinklers are mounted. Each of the sprinklers consists of a base that is connected to at least two arch-shaped holders that hold the bushing with a diffuser fixed on it, made in the form of a diffuser with a flap in the direction of the base, with petals located along the conical surface of the belt. Inside the divider there is additionally installed a sprayer made in the form of a cup, that is fixed by means of at least three radially horizontally arranged flat petals to the inner surface of the dissector. Cup axis coincides with the axes of a through channel of a fitting and a bushing, and its inner cavity is directed towards the bushing. Glass bulb with its lower end rests on the valve through an elastic gasket fixed to the external end face of the valve, that in return rests against the base in the form of a tapered threaded connection and a through channel. Glass bulb with its upper end rests against the holder, installed in the lower part of the sleeve, with a divider attached to it. Holder is installed in the lower part of the bushing with a gap. Sprinkler sprayer cup is made in the form of a hemisphere with an internal cavity, an equidistant and congruent outer spherical surface of the cup. Sprinkler sprayer cup can be made in the form of a truncated cone with an internal cavity directed towards the sleeve and made in the form of a truncated cone surface, an equidistant and congruent outer surface of the cup. On the outer surface of the diffuser, made in the form of a diffuser, an additional conical dissector is fixed, configurated in the form of a truncated cone. Smaller base of the truncated cone of an additional conical dissector is fixed on the outer surface of the dissector. Larger base of the truncated cone faces the arcuate bushing holders with the divider attached to it. Diameter of the larger base of the truncated cone of the additional conical dissector is in the middle of the interval between the diameter of the belt with the petals located on the forming conical surface of the belt and the diameter of a circle present around arched holders connected to the base of the sprinkler.

EFFECT: technical result is increased efficiency of fire extinguishing ensured by introducing high-speed elements in common circuit for automatic fire extinguishing system.
