KOCHETOV SPRINKLER 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 a sprinkler irrigation system, consisting of a base in the form of a fitting with a tapered thread and a through channel, and the base of the sprinkler is connected to at least two arcuate holders that hold the sleeve with a divider attached to it, made in the form of a diffuser with a belt tilted toward the base, with lobes arranged along the generatrix of the conical surface of the girdle, inside the divider is additionally installed above the outlet of the bushing the 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 poppet valve with a glass bulb is installed in the channel, which is supported by a valve through a threaded washer, attached to the threaded part of the channel, with the upper part of the glass bulb fixed in an elastic gasket located in the sleeve, and the inner surface of the sleeve has a taper in the form of a divider, and the glass bulb is pressed against the elastic gasket by means of a threaded washer, and part of divider petals is made bent towards larger base of conical surface of diffuser, while bent petals are made alternating with 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.
