The beneficial effects of the utility model:
1, the utility model Explosion suppressor quick opening valve, when trigger triggers after gas generating agent, a large amount of pressurized gas that gas generating agent produces promote piston and move, valve rod is under the effect of piston pulling force simultaneously, the stressed fracture of tension failure band on it, the Explosion suppressant entrance on valve body and Explosion suppressant outlet realize and being communicated with; Because gas generating agent can produce rapidly a large amount of pressurized gas, so tension failure band can be broken fast, thus make Explosion suppressor can be after receiving actuating signal rapid response ejection Explosion suppressant, the datonation-inhibition response time is short.
2, the utility model Explosion suppressor quick opening valve, valve rod bar footpath increases can make the corresponding increase of Explosion suppressant entrance, has effectively solved to increase to open bore and shorten the contradiction between the response time, and Explosion suppressant entrance increases can improve the effect of dusting, and strengthens datonation-inhibition effect.
3, the utility model Explosion suppressor quick opening valve, pressurized gas and extraneous seal isolation that gas generating agent produces, environment does not impact to external world, has guaranteed Safety performance.
Accompanying drawing explanation
Fig. 1 is the first mode of execution structural representation of quick opening valve for the utility model Explosion suppressor;
Fig. 2 is the second mode of execution structural representation of quick opening valve for the utility model Explosion suppressor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment Explosion suppressor quick opening valve, comprise valve body 1, piston 2, valve rod 3, described piston 2 coordinates with the inner chamber slipper seal of valve body 1, on described valve body 1, be provided with Explosion suppressant entrance 7 and Explosion suppressant outlet 8, the leading portion of described valve rod 3 is fixed on piston 2, and the back segment of described valve rod 3 is fixed in Explosion suppressant entrance 7 and with Explosion suppressant entrance 7 and is sealed and matched;
Between the intracavity bottom of the end of described piston 2 and valve body 1, be provided with the aerogenesis chamber 4 of sealing, on described piston 2, be also provided with for triggering the trigger 6 of aerogenesis chamber 4 gas generating agent 5 aerogenesis;
On the back segment of described valve rod 3, be provided with tension failure band 301, piston 2 by aerogenesis chamber 4 mesohigh gas push situations under, described tension failure band 301 is pulled off, simultaneously described Explosion suppressant entrance 7 and Explosion suppressant export 8 conductings.
The present embodiment Explosion suppressor quick opening valve, when trigger 6 receives after actuating signal, it just triggers gas generating agent 5, a large amount of pressurized gas that gas generating agent produces, piston 2 moves under pressurized gas promote, simultaneously valve rod 3 stressed fracture of tension failure band 301 on it under the effect of piston pulling force, the Explosion suppressant entrance 7 on valve body 1 and Explosion suppressant outlet 8 realize and being communicated with; Because gas generating agent 5 can produce rapidly a large amount of pressurized gas, so tension failure band 301 can be broken fast, thus make Explosion suppressor can be after receiving actuating signal rapid response ejection Explosion suppressant, the datonation-inhibition response time is short.
