KOCHETOV DELUGE SPRAYER Russian patent published in 2018 - IPC A62C37/12 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to fire fighting equipment, in particular to deluge sprinklers for fire-extinguishing with a finely dispersed liquid. Sprinkler is designed for spraying liquid in automatic stationary fire extinguishing installations. This is achieved by the fact that in the deluge sprinkler, consisting of a base in the form of a chimney with a channel and a divider fixed to the holders, base of the sprinkler is connected to at least two arched supports that hold the bushing with the divider attached to it, made in the form of a diffuser with a belt bent towards the base with petals located along the generatrix of the conical surface of the girdle, and in addition a sprayer, made in the form of a cylinder, on the external surface of which a screw thread is made, the cylinder being fixed, with the possibility of rotation, by means of two axes to the inner surface of the dissector, a part of the lobes is bent towards the larger base of the conical surface of the diffuser, while the bent petals are made alternating with the petals unbent.

EFFECT: technically achievable result is the increase in the fire extinguishing in automatic stationary installations effectiveness due to the surface irrigation uniformity and the finely-dispersed droplet spraying uniformity.
