Gas replenishment process: gas extinguishing agent at self-locking joint 47, inflation inlet 421 through container value 40, a part of gas warp
Air entry 422 enters foamite container 50, p*s1 > (f1+p0*s2), valve element 43 is partly upper to be moved, a part of gas through valve element 43 with
Gap between valve seat 42 enters and holds air cavity 431, as (p*s2+f1) > p*s1 when, valve element 43 moves down air entry 422 and gas vent
423 seal up.
Deflation course: when motor 10 starts, connecting shaft 11 drives internal key set 31 rotation, thus drive top cutter head 32 down to transport
Move and puncture seal membrane 41, hold the passage that the venthole 321 through pushing up cutter head 32 for the gases at high pressure in air cavity 431 enters bonnet 46
463 discharges, hold pressure in air cavity 321 and reduce rapidly, and p*s1 > (f1+p0*s2) moves on valve element 43, the gas that 50 kinds of foamite container
Body extinguishing chemical enters into gas vent 423 through air entry 422, and control system is (not shown) to control respective line hidden to fire is detected
The battery case suffered from is put out a fire.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
