SPRINKLER Russian patent published in 2018 - IPC A62C31/02 B05B1/04 

FIELD: fire safety.

SUBSTANCE: invention relates to fire fighting equipment and can be used in industrial and civilian facilities with increased fire danger for localization of fires, as well as for effective fire extinguishing in industrial premises with the use of automatic fire extinguishing systems. This is achieved by the fact that in the sprinkler containing the body, the spraying device and the automatic operation element for exceeding the set temperature in the room, the body is made in the form of a cylindrical sleeve with windows on its side surface, and at one end of the cylindrical sleeve facing the spraying device there is a partition, the spraying device being in the form of an outlet formed by a part of a spherical surface having a thickness of "s" type, and where the radial slots are made, wherein the socket is fixed to the end surface of the sleeve by means of at least two arcs arranged along a conical surface, the upper part of which is fixed to the partition, and an outlet is attached to the lower part, which is part of the spherical surface bounded by the inner and outer hemispheres and having a thickness "s" lying in the range of 1÷5 mm, the center of the hemispheres lies on the line connecting the axes of the cylindrical sleeve and the axis of the partition, and on the spherical surface, on its outer side, at least three grooves are made, the axes of which are located on the radial lines with respect to the hemisphere, and in the peripheral part of the hemisphere, at least three chokes are made, the centers of which lie in the plane, parallel to the diametral plane of the hemisphere, which is perpendicular to the axis of the cylindrical sleeve, and whose axes intersect at a point lying on the axis of the cylindrical sleeve, and constitute an acute angle with this axis in the plane of the drawing.

EFFECT: improvement of efficiency of fire extinguishing due to establishment of the sprayer which enables to obtain a fine flow of fire extinguishing liquid or foaming agent solution.
