Description
Technical field
The utility model is related to a kind of fire-fighting spraying cover.
Background technology
Froth fire extinguishing system refers to the fire suppression measures being made up of equipment set and program.Fixed foam extinguisher system by
Fixed foam solution fire pump, foam liquid storage tank, proportioner, the conveyance conduit of foam mixing liquid and foam-generating device etc.
Composition, and be connected with water supply system.When a fire, first start fire pump, open related valve, system can be implemented
Fire extinguishing.The foam jet mode of fixed foam extinguisher system can be using injection and subsurface injection mode on liquid.The system has one
Equipment component is fixed, can be started in time, and another part is unfixed, when occurring fire, into scene and fixing equipment
Constitute fire extinguishing system fire extinguishing.It is different according to the equipment of fixed installation, there are two kinds of forms：A kind of is to produce dress provided with fixed foam
Put, foam mixing liquid pipeline, valve.When a fire, foam mixing liquid by foam truck or power pump by water band from
Reserved interface enters.Another is that, provided with fixed foam firefighting pumping plant and corresponding pipeline, during fire extinguishing, will be moved by water band
Dynamic foam-generating device (such as foam gun) is connected with fixed pipeline, constitutes fire extinguishing system.(by fire fighting truck and fire hose with
The foam that fixed foam producer is connected or is made up of fixed foam station and fire hose, foamed pipe rifle or hook pipe etc. goes out
Fiery system).Semi-fixed type froth fire extinguishing system is applied to the first, second with stronger mechanical fire-extinguishing facility, the storage of Class C liquid
Easily occurs the local place of fire in tank field or the larger place of single tankage size and petrochemical production device area.
Froth fire extinguishing system is typically all to be applied to extinguishing pipe ejecting extinguishing, but applied to the spray head also right and wrong of fire-fighting
Often it is rare, it should be there is presently no.Single sprinkling fire effect in certain degree is not good.
The content of the invention
The purpose of this utility model is to provide a kind of fire-fighting spraying cover.
The utility model solves its above-mentioned technical problem and uses following technical scheme：A kind of fire-fighting spraying cover, its
Mainly it is configured with：Pipe fitting a, pipe fitting b, snap ring, foaming groove, spray bubble pipe, splitter, gaseous core, the spray mouth of pipe, groove lid, described pipe
Part a is fastened by snap ring between the two with pipe fitting b；At described pipe fitting b concave side walls provided with foaming groove, foaming groove one end with
Spray bubble pipe connects, and described spray bubble pipe is located at the center of the spray mouth of pipe；
The port part of the spray bubble pipe is sealed with a diaphragm seal, is built-in with splitter in spray bubble tube hub position, shunts
Positive contraposition has installed gaseous core outside piece；It is marked with outside foaming liquid, and the groove that foams and is sealed by groove lid in described foaming groove.
Further, described gaseous core one end connection compression gas tank.
Further, it is interaction relation that the valve of described gaseous core opens both with the spray in pipe fitting b.
The beneficial effects of the utility model：Using, provided with foaming groove, foaming groove one end is with spraying bubble pipe at pipe fitting b concave side walls
Connect, spray bubble pipe is located at the center of the spray mouth of pipe；Bubble tube hub position is built-in with outside splitter, splitter just to position
Provided with gaseous core；The technological means of foaming liquid is marked with foaming groove, common fire-fighting spraying head is realized while water spray, energy
Enough spray regimes for realizing the foam composition water in a period of time, improve extinguishing effect.

Embodiment
1-2 makes a detailed explanation to embodiment of the present utility model below in conjunction with the accompanying drawings.
Embodiment：A kind of fire-fighting spraying cover, it is mainly configured with：Pipe fitting a1, pipe fitting b2, snap ring 3, foaming groove 4, spray bubble pipe
5th, splitter 6, gaseous core 7, the spray mouth of pipe 8, groove lid 9, described pipe fitting a1 and pipe fitting b2 are fastened by snap ring 3 between the two；
Provided with foaming groove 4 at described pipe fitting b2 concave side walls, foaming one end of groove 4 connects with spray bubble pipe 5, described spray bubble pipe 5
In the center of the spray mouth of pipe 8；
The port part of the spray bubble pipe 5 is sealed with a diaphragm seal, and splitter 6 is built-in with spray bubble pipe 5 center, point
The outer positive contraposition of flow 6 has installed gaseous core 7；Foaming liquid is marked with described foaming groove 4, and the groove 4 that foams is outer close by the institute of groove lid 9
Envelope.
The described one end of gaseous core 7 connection compression gas tank.
It is interaction relation that the valve of described gaseous core 7 opens both with the spray in pipe fitting b2.
Design principle starting point of the present utility model：Foaming liquid has extremely strong unstability, is rocking or is shaking
The substantial amounts of foaming agent of Shi Qineng products.
The utility model implementation process：When fire dangerous situation occurs, interlink alarm system can open water valve and be noted to pipe fitting a1
Enter, so that the pipe fitting b2 spray mouth of pipe 8 sprays spray, because valve and the spray in pipe fitting b2 of gaseous core 7 open both
For interaction relation, therefore now the valve of gaseous core 7 is also turned on, and in the moment of unlatching, the gas of its high pressure blows and hits splitter 6 and make
The Quick shaking of its left and right swings dynamic, the moment waved in splitter 6, and it is fixed on the diaphragm seal of the port part sealing label of spray bubble pipe 5
Torn, now the gas of high pressure can blow percussion bubble groove 4, and the expanding foam solution moment in groove 4 of foaming becomes foam, and in a steady stream not
Disconnected outflow.Its foam is taken away in spray bubble pipe 5 by the spray that the spray mouth of pipe 8 sprays, so that whole spray is that foam goes out
Fire.
Splitter 6 has two effects in the utility model：One is puncturing diaphragm seal so that the expanding foam solution in foaming groove 4
It can be contacted with gases at high pressure；The second is when gases at high pressure blow and hit, the liquid foamed in groove 4 can be caused due to vacillating now to the left, now to the right
Because left and right air inlet is unbalanced and produces substantial amounts of foaming.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
