SU1517968A1 - Apparatus for fire-fighting protection of reservoir - Google Patents

Abstract

The invention relates to fire fighting equipment, namely, extinguishing fires with air-mechanical foam in tanks with oil or oil products, and allows to simplify the design while simultaneously increasing the reliability of sealing the tank through the use of an elastic chamber. The device for fire protection of tanks contains a foam generator 1 adjacent to the wall of tank 2. In the upper wall of tank 2, a cover 3 with a latch 4 is inserted into a circle-cut window. The mating surfaces of cover 3 and walls of tank 2 are in the form of gutters 5. An elastic chamber 6 is inserted into the space between the grooves 5, into which air is pumped through the spool 7 by means of a rubber hose 8, the chamber 6 fills the space between the grooves 5, creating a sealing of the vapor-air space of the tank 2 from the external environment. The cavity of the elastic chamber 6 is connected to the sprinkler head 9 by means of the tube 10. To induce the opening of the cover 3 into the cavity of the tank 2, a spring 11 is used, which is mounted on the latch 4. 1 Cp. File, 1 sludge.

rolls back into the tank, allowing the air-mechanical foam to flow unhindered into the tank.

The use of an elastic sealing chamber will simplify the design and at the same time increase the reliability of the sealing of the cavity of the tank, which will eliminate the danger of oil leaking into the environment, the environment, and the elimination of explosive concentrations.

Claims (2)

1. A device for fire protection of the tank, containing a foam generator adjacent to the station; a tank container with a lid with a seal (a seal that is jointly hinged with a retainer, which separates tightly the cavity of the foam generator with a tank cavity, in order to simplify construction and increase the reliability of sealing, the cover is placed in the same plane with the wall of the tank with the execution of mating surfaces in the form of grooves, and the sealing of the cover is made in the form of a hollow elastic chamber filled with air and gap of between the mating surfaces of the cover and the tank wall, wherein the chamber floor elastic pnev.maticheski coupled with media (1H) M ud () zhapii and venting, BEU - de 1N1m device and raz.meschennym in corolla light on the internal cavity of the tank. 2. The device according to claim 1, wherein the 410 retainer is provided with a spring which creates a opening (and / or 1 for opening the lid).
