2, device poised state and operating principle
When device is in poised state, pin 262 to be subject to by air pressure be applied to load on the second piston 261 end face, size is
direction to the right; Now, pin 262 right side is positioned at groove 244 place of first piston 24, and pin 262 is subject to gas pressure load
dry powder weight acts on the component mg*sin α * cos α on frustum face, and wherein mg represents that dry powder acts on the gravity of valve body 2, and valve body 2 is to its reaction force F
1, the stiction F of O shape circle
f, so time equation of equilibrium be:
When the slow decompression of the inner chamber visiting fire tube 4, P
1drop to P
1', now, due to
then F
1drop to F
1', F
fdrop to F
f', still left, pin keeps balance, namely in direction
And large chamber pressure be less than pressure in tank body 1, tonifying Qi is carried out in the automatic inner chamber chamber to visiting fire tube 4 by the gas in tank body 1, reaches original poised state.
When visiting fire tube 4 explosion, visiting fire tube 4 cavity pressure gas and releasing rapidly, now, the frictional force of O shape circle is reverse, namely to the right, due to
therefore pin 262 is moved to the left, device action starts.
3, course of action
When there is the condition of a fire, temperature raises, spy fire tube 4 is caused to burst after reaching the operating temperature visiting fire tube 4, pin 262 moves to left and departs from groove 244, first piston 261 moves downward along valve pocket 32 and falls within support level 35 place under the effect of gas pressure, dry powder is sprayed to spattering powder dish 5 and diffusing to guard plot to the periphery by meal outlet 31 by injection channel 33 under the promotion of gas pressure, realizes fire extinguishing object.
Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable change or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
