Description
Technical Field
The utility model relates to a fire extinguishing apparatus specifically is a sound construction, avoids cracked low multiple air foam generator in installation and transportation.
Background
The low multiple air foam generator is fixedly arranged on the oil tank, and sprays foam on the liquid to the surface of the combustible liquid, so that the whole combustion surface is quickly covered to extinguish the fire, and the fire is effectively prevented from spreading; it is mainly suitable for the production, storage, transportation and use places of inflammable and combustible liquid, in particular for fighting storage tank fire and large-area flowing fire.
In the existing horizontal low-multiple air foam generator, foam mixed liquid with pressure is provided by a foam mixing device, and enters a storage tank for extinguishing fire after breaking sealing glass under the action of pressure after entering the foam generator through a fire-fighting pipeline; because the foam concentrate must break through the glass before it can enter the tank, the glass must be thin and often breaks during installation and transportation, particularly after installation on the tank, which can cause the glass to break due to the unstable gas pressure in the tank when the tank is filled with the medium, thereby causing the leakage of toxic and harmful gases in the tank.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem to a sturdy structure is provided, cracked low multiple air foam generator in installation and transportation is avoided.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a low multiple air foam generator, includes the foaming casing, and the upper end and the lower extreme of foaming casing are provided with upper cover and ladder connecting pipe respectively, and the lower extreme of ladder connecting pipe is provided with the nozzle, and the ladder connecting pipe stretches into and is provided with the metal sealing plate that is used for sealing the nozzle in the end cover flange of the internal end of foaming casing.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
the metal sealing plate is used, and the problem of gas leakage in the tank due to breakage caused by installation, transportation and over-bearing limit of negative pressure in the tank is avoided by utilizing the characteristic that the metal is good in toughness and not easy to break.
The device has simple structure, few parts and easy realization.
Preferably, the present invention further provides:
sealing gaskets are arranged on the upper part and the lower part of the metal sealing plate, and are fixedly embedded at the upper end port of the stepped connecting pipe through a glass gland and a bolt; when the low-multiple air foam generator is in a non-working state, the metal sealing plate is pressed on the step connecting pipe by the glass gland, and the sealing effect is achieved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic view of the structure at A in FIG. 1;
fig. 3 is a schematic structural diagram of an upper cover according to an embodiment of the present invention.
In the figure: an upper cover 1; a foam housing 2; a metal sealing plate 3; a step connecting pipe 4; a sealing gasket 5; and a glass gland 6.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 to 3, a low multiple air foam generator, including foaming housing 2, the upper end and the lower extreme of foaming housing 2 are provided with upper cover 1 and ladder connecting pipe 4 respectively, the lower extreme of ladder connecting pipe 4 is provided with the nozzle, ladder connecting pipe 4 stretches into and is provided with the metal seal plate 3 that is used for sealing the nozzle in the end cover flange of foaming housing 2 internal end, metal seal plate 3 is the sheet metal, the thickness of metal seal plate 3 is 0.35mm, make through precision finishing by Q235 or various steel sheet or plumbous, all be provided with seal ring 5 about metal seal plate 3 and inlay the upper end port department at ladder connecting pipe 4 through glass gland 6 and bolt fastening, when making low multiple air foam generator at non-operation state, metal seal plate 3 is pressed on ladder connecting pipe 4 by glass gland 6, play sealed effect.
When the foam generator is used, when pressure foam concentrate is flushed into the foam generator, the metal sealing plate 32 is impacted by the foam concentrate, an opening with the diameter larger than 80% of the section diameter is torn in a preset area, and the foam concentrate enters the tank body to extinguish fire.
The utility model discloses an use metal closing plate 32, utilize the good cracked characteristics of difficult of metal toughness, avoid exceeding the problem device simple structure, the part is few, realize easily that the breakage leads to jar interior gas leakage because of installation, transportation and jar interior negative pressure.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
