METHOD FOR REDUCING INERTIA OF SPRINKLER IRRIGATOR ACTUATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC A62C35/68 A62C37/11 

FIELD: fire extinguishing.

SUBSTANCE: group of inventions relates to a method of reducing inertia of sprinkler irrigator actuation and a device for its implementation. Method is applicable in automatic water and foam fire extinguishing installations, equipped with water and foam sprinkler irrigators with heat-sensitive elements of the thermal lock, made in the form of glass bursting thermal flasks, having a sprayer made in the form of a housing and a socket and directed by the socket vertically upwards. Application is limited to rooms with height of up to 20 m. Method is characterized by performing the following steps: connecting horizontally installed heat-collecting plate of square shape, having a central hole, with a welded coupling; controlling the horizontal position of the heat-collecting plate using the building level, while ensuring the alignment of the central hole and the sprinkler irrigator, which is installed in the welded coupling, the permissible deviation from alignment shall be not more than 10 mm per 1,000 mm of the axis length; controlling the distance from the heat-collecting plate to the underlying outlet of the sprinkler irrigator, distance should be within 10 to 50 mm; providing free open space between heat collecting plate and sprinkler irrigator, open with possibility of passing through hole in heat-collecting plate of concentrated convective heat flow in case of fire upwards coaxially with sprinkler irrigator, providing intensive heating by concentrated convective heat flow of heat-sensitive element of thermal lock of sprinkler irrigator. Device for method is made in form of concentrator of heat convective flows, comprising a horizontally located heat-collecting plate above a sprinkler irrigator with a socket installed in a welded threaded coupling, heat-collecting plate is made of square shape with central hole coaxially with sprinkler irrigator with provision of free open space between heat-collecting plate and sprinkler irrigator, heat-collecting plate is installed on the welded coupling by means of a clamp covering the cylindrical surface of the welded threaded coupling, and four tape suspensions symmetrically distributed along the coupling circumference, lower ends of suspensions are bent and coupled with clamp and fixed on it by means of screw connections, suspensions are directed to peripheral part of heat-collecting plate, at that upper ends of suspensions are bent and conjugated with heat-collecting plate and fixed on it by means of fasteners.

EFFECT: invention discloses a method of reducing inertia of sprinkler irrigator actuation and a device for its implementation.
