Drench.
The course of work of the small space fire-fighting equipment 100 of the utility model embodiment is described referring to Fig. 1-3.
Specifically, small space fire-fighting equipment 100 may be mounted in passenger car, can also be arranged on mobile vehicle
Engine bin in, during routine use, when residing for the tank body 10 of small space fire-fighting equipment 100 environment temperature rise
When, the pressure increase in tank body 10, when increasing to predetermined value, relief valve 20 is opened, and outwards pressure release, when pressure release to tank body 10
When interior pressure reaches predetermined value, stop pressure release, thus, it is possible to carry out real-time guard to tank body 10, it is to avoid due in tank body 10
The blast that pressure is excessive and occurs.
It is likely to be at due to tank body 10 under long-term use state, user can be according to the position of labeling section to tank body 10
Pressure state be monitored.
As shown in Fig. 2 when the pressure in tank body 10 is in the normal condition being adapted in use to, now having in tank body 10 and filling
Pressure in the fire-fighting medium of foot, tank body 10 is larger, promotes the extruding elastic component of piston 42 so that extension bar 44 is protruding larger
Length, at this moment labeling section 45 is in the top of limiting unit 412, thus, it is possible to judge that tank body 10 is in normal condition.
As shown in figure 3, when the pressure in tank body 10 diminishes even equal with external atmosphere pressure, now fire-fighting in tank body 10
Medium is not enough, it is impossible to complete fire-fighting task, because the pressure in tank body 10 is smaller, and elastic component 43 promotes piston 42 to move downward,
So that extension bar 44 extends inwardly into larger length, at this moment labeling section 45 is in the lower section of limiting unit 412, it is impossible to it was observed that, thus,
It may determine that tank body 10 is in non-normal use state.
The pressure in tank body 10 is monitored by the way of the above, no matter whether tank body 10 was provided out fire-fighting Jie
Matter, as long as being that can conclude that whether tank body 10 is in upstate according to judged result.
