FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment, to manual and stationary devices for generation of air-mechanical hybrid foam of medium expansion rate or sprayed water. In installation combined fire extinguishing, comprising a cylindrical housing, a mesh cassette installed inside the housing and a nozzle with a connection pipe for supplying a fire extinguishing substance, housing is made of metal thin-walled with annular projection concave inside the housing on the side of foam jet or sprayed water outlet and with annular projection outward from the nozzle side, mesh cassette is made of three coaxially installed with interference one inside the other inner, intermediate and outer annular rims with side cylindrical surfaces and two meshes arranged with a gap relative to each other, one of which is fixed by its edges in the gap between the mating side surfaces of the outer and intermediate rims, and the other is fixed by its edges in the gap between the mating side surfaces of the intermediate and inner rims, and the nozzle is attached to the housing by means of centring stops. At the same time cassette of meshes is installed inside the housing on the side of the nozzle with thrust against the annular projection concave inside the housing and is located so that the mesh fixed by the edges between the outer and intermediate rims faces the nozzle, and the mesh fixed by its edges between the intermediate and inner rims faces towards the foam jet outlet.
EFFECT: increasing the efficiency of extinguishing emergency transport, forest, industrial and other fires.
