Internal cavity is connected to by diversion trench 132 with expansion chamber 111；When work, when tank body 1 is inverted, the elastic force fit plate 6 of opening
On the inner wall that elastic filter screen 11 can be squeezed under the gravity of pressing steel ball 7, and then elastic filter screen 11 is made to squeeze expulsion bladder 13, in turn
Increase the rate that expulsion bladder 13 allots foaming agent, meanwhile, the foaming agent in expulsion bladder 13, can be by leading after the compression of expulsion bladder 13
Chute 132 enters in expansion chamber 111, and then the elastic filter screen 11 after expansion can also spray a part of foaming agent, Jin Erzeng
Big foaming agent and mixed sodium bicarbonate solution and aluminum sulfate solution mixed effect, and then increase the foaming effect of foaming agent.
Specific workflow is as follows:
When work, aluminum sulfate solution is filled into conical flask 2, sealing plate 4 is symmetrically hinged on to the inside of conical flask 2, it is close
The compressed spring 5 of 4 bottom end of sealing plate setting is in compressive state, by the way that the pressing steel ball 7 being arranged on elastic force fit plate 6 to be engaged to
In engaging slot 41, the extension spring 8 of setting is in tensional state, and then can by the cooperation of pressing steel ball 7 and extension spring 8
The aluminum sulfate solution filled in conical flask 2 is sealed, the conical flask 2 after sealing is fixed on tank body 1 by screen pack 3
It is interior；When fire occurs for the external world, user of service is inverted the sodium bicarbonate solution in tank body 1 to tank body 1 by being inverted tank body 1
Top, while the pressing steel ball 7 of 2 bottle mouth position of inverted conical flask setting is de- out of engaging slot 41 under the gravity of itself
From the gravity of pressing steel ball 7 can be such that elastic force fit plate 6 opens, while hinged sealing plate 4 is in itself gravity and compressed spring
Can be made under 5 reaction force, so make the aluminum sulfate solution in conical flask 2 in the state of inversion with the carbon in tank body 1
Sour hydrogen sodium solution carries out mixing and generates chemical reaction, generates a large amount of carbon dioxide gas, opens simultaneously valve, makes in tank body 1
Carbon dioxide foaming by jet pipe spray, and then carry out extinguishing operation.
