(54) FIREPROOFER

(57) The invention relates to fire fighting equipment, in particular, to means limiting the spread of flame in technological communications of the chemical and gas industry, and allows to increase the efficiency of the flame retardant operation due to the orderly compression of the flame retardant nozzle. When a consumer ignites a combustible gas, a fire pipe 5 enters a flame arrestor and explodes gas in the space between the lid 4 and the aperture plate 1 1, while the explosive pressure acts on the plate 11 and through the valve 10 is transferred to the flame exchanger 12, which the downward movement compresses the filler grains to the state of tight packing; at the same time, the valve 10 is wedged in the saddle 7 of the partition 6 and is kept there in the stuck state for as long as it is necessary for the operating personnel to eliminate Causes and consequences of combustible gas ignition. 1 il.

FIELD OF THE INVENTION The invention relates to fire fighting equipment, namely, to means limiting the spread of flame in the process communications of the chemical and gas industry.

The purpose of the invention is to drink:) the effectiveness of the fire barrier by means of the compression of the filler flame and the nozzle.

The drawing shows the proposed or non-deterrent, a general view.

The arrester consists of a cylindrical body 1, a lower 2 with an outlet nozzle 3, an upper 4 with an inlet nozzle 5, a transverse partition f) with a saddle 7, which divides the device into two chambers: the upper one is an explosion}) and the lower is a localization one. The latter has a fixed grating 8, n; j of which is located a granular flame arrester filler 9. The movable part of the flame arrester consists of a valve 10 with a conical flow, with a pressure plate with holes 11 located at one end, and a flame arrester at another end 12. To limit the movement of the movable part of the device, the housing 1 has a protrusion 13 on the upper part.

Flame arrester works as follows m.

Under normal conditions, the combustible gas passes successively through the pipe 3, 8, granular filler 9, the plastics trough 12, the annular gap between the bulkhead {) and the conical thickening 10, the holes in the plate 1 I and the pipe 5 goes to pot |) ebitlk). In this case, the movable part of the flame arrestor under the action of its own pressure, 1 of the combustible gas rises upward to the emphasis only) and paragraphs 1 1 vs 1.3, Grains).

Mr. state. The distances between them increase, which reduces the hydraulic resistance of the flame arrestor to the gas flow.

When a consumer ignites a combustible gas, a flame arrester enters the flame through the pipe 5 and explodes the gas in the space between the lid 4 and the plate 11 with dust. The explosive pressure acts on the plate I1 and through the valve 10 is transferred to the flame suppressor 12, which, when moving downward, compresses the filler grains to the state of dense packing. At the same time, the valve 10 is wedged in the saddle 7 of the partition 6 and is kept there in a wedged state for as long as it is necessary for the operating personnel to eliminate the causes and consequences of a hot gas ignition. After that, the movable part of the flame arrester is removed from the stuck position by feeding high-pressure inert gas to the inlet 0 3, after which the flame arrestor is ready for operation.

Claims (1)

Invention Formula 5 the arrester, comprising a housing with inlet and outlet nozzles, inside of which a flame extinguishing nozzle with a flame arrestor is installed, and a shut-off valve installed with a possibility of movement in a conical hole of the seat, differing 0 PM that, in order to increase the efficiency of the flame arrester due to the ordered compression of the flame retardant nozzle filler, the flame arrestor is equipped with a movable plate with holes placed on the side of its inlet nozzle, 5 while the valve ends are fixed between the movable plate and the flame arrester, and its seat is placed between them.
