Description
Technical Field
The utility model relates to an air foam generator, especially a striking type low multiple air foam generator structure.
Background
The low multiple foam generator is fixedly installed on an oil tank, sprays foam on liquid to the surface of combustible liquid, quickly covers the whole combustion surface, extinguishes fire and effectively prevents the spread of fire. It is mainly suitable for the production, storage, transportation and use places of inflammable and combustible liquids. Is especially suitable for fighting storage tank fire and large-area flowing fire. The existing horizontal low-multiple foam generator is provided with foam mixed liquid with pressure by a foam mixing device, and the foam mixed liquid enters the foam generator through a fire-fighting pipeline and then enters a storage tank to extinguish fire after breaking through sealing glass under the action of the pressure. Because the foam concentrate breaks through the glass before entering the tank, the glass must be thin and often breaks during installation and transportation, and particularly after being installed on the tank, the glass breaks due to unstable air pressure in the tank when the tank is filled with the medium, so that toxic and harmful gas in the tank leaks.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and providing a striking type low multiple air foam generator structure, prevent that sealed glass from bearing the limit and make the glass breakage lead to jar internal gas leakage.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a striking type low multiple air foam generator structure, includes the casing, is equipped with coaxial feed liquor tube hole and liquid outlet pipe hole in the casing, and the lower port installation nozzle in feed liquor tube hole, the upper end lid in liquid outlet pipe hole closes the organic glass lid, and the spout of nozzle inlays the dress firing pin, and the firing pin is located the top of organic glass lid.
Adopt above-mentioned technical scheme the utility model discloses compare with prior art, beneficial effect is:
simple structure, the part is few and easily realize, has avoided making sealed glass breakage lead to the problem of jar interior gas leakage because of installation, transportation and jar interior negative pressure surpass sealed glass and bear the limit.
Further, the utility model discloses an optimization scheme is:
the firing pin is in interference fit with the nozzle.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: a housing 1; 1-1 parts of liquid inlet pipe hole; a liquid outlet pipe hole 1-2; a nozzle 2; a nozzle seal ring 3; a striker 4; a sealing glass sheet 5; an organic glass cover 6; a bolt 7; a sealing glass ring 8; flange bolts 9; a flange seal 10; an outlet flange 11; a screen 12.
Detailed Description
The present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, the embodiment is a collision type low-multiple air foam generator structure, which is composed of a shell 1, a nozzle 2, an organic glass cover 6 and the like, wherein a vertical liquid inlet pipe hole 1-1 and a vertical liquid outlet pipe hole 1-2 are arranged in the shell 1, the liquid inlet pipe hole 1-1 is coaxial with the liquid outlet pipe hole 1-2, and the liquid inlet pipe hole 1-1 is located above the liquid outlet pipe hole 1-2. The upper end opening of the liquid outlet pipe hole 1-2 is a stepped hole, the upper end opening of the liquid outlet pipe hole 1-2 is sequentially provided with a sealing glass sheet 5 and an organic glass cover 6, the sealing glass sheet 5 is circular and horizontally arranged in the stepped hole, a sealing glass ring 8 is respectively arranged between the lower surface of the sealing glass sheet 5 and the stepped surface of the upper end opening of the liquid outlet pipe hole 1-2, and between the upper surface of the sealing glass sheet 5 and the organic glass cover 6, the organic glass cover 6 is positioned on the upper end surface of the liquid outlet pipe hole 1-2, and the organic glass cover 6 is connected with the upper end surface of the liquid outlet pipe hole 1-2 through a bolt 7. A flange seal 10 and an outlet flange 11 are sequentially arranged at the lower end opening of the liquid outlet pipe hole 1-2, and the outlet flange 11 is connected with the liquid outlet pipe hole 1-2 through a flange bolt 9.
The lower port of the liquid inlet pipe hole 1-1 is provided with a nozzle 2, the nozzle 2 and the liquid inlet pipe hole 1-1 are provided with a nozzle sealing ring 3, a nozzle opening of the nozzle 2 is embedded with a firing pin 4, the firing pin 4 is in interference connection with the nozzle 2, the lower end of the firing pin 4 is in a conical structure, the firing pin 4 is positioned above an organic glass cover 6, and the firing pin 4 is a steel piece which is processed precisely. A filter screen 12 is arranged at the port at one side of the cavity between the liquid inlet pipe hole 1-1 and the liquid outlet pipe hole 1-2, and a side cover is arranged outside the filter screen 12. When the foam generator is in a non-working state, the organic glass cover 6 is pressed on the sealing glass ring 8 to play a sealing role, and the firing pin 4 is embedded in the nozzle of the nozzle 2 and cannot fall off through interference fit. When the foam generator is in a working state, when pressure foam liquid is flushed into the foam generator, the firing pin 4 is pushed under the action of pressure, the firing pin 4 is ejected out of the nozzle 2 and impacts the organic glass cover 6, the organic glass cover 6 and the sealing glass sheet 5 are broken under the impact of the firing pin 4, and the foam liquid enters the tank body to extinguish fire.
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 structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
