State.
After valve 2 is locked in closure state for a period of time, the space of the inner side of door leaf 12 is with the space in outside in isolation
State, the heat that the people inside antiaircraft tunnel comes out with machine cannot be delivered to the external world by air-flow, cause antiaircraft tunnel
High in internal temperature, air pressure rises after air heats expansion.Detected and the air pressure signal of telecommunication will be surveyed by baroceptor 321 and passed
Pass control unit 33.
Exported by reference to voltage generation circuit 331 and survey the reference voltage that air pressure voltage signal is made comparisons, according to normal
Atmospheric pressure, presets an excess air pressure scope, and in the range of default excess air pressure, the value of the output of baroceptor 321 is less than ginseng
Examine voltage, comparator output low level, Jing be still behind the door low level, now audion is not turned on；
When the value of the output of baroceptor 321 is more than reference voltage, comparator output high level is input to delay circuit,
Time delay is exported afterwards for a period of time, afterwards with comparison output instantly and rear output, if comparison output instantly is still high level, with
The signal of door output is high level, and turn-on transistor, relay obtains electric, inner-core adhesive armature S, conducting direct current power supply and electricity
Magnet 312, the generation magnetic field of electric magnet 312 is simultaneously attracting with magnet 311, and band driven fork 310 swings, so that the projection on lock 21
22 depart from valve 2, and valve 2 is resetted by action of gravity, folding, exposes air vent 11, the air of the inner side of door leaf 12
After communicating with outside air, the air pressure in antiaircraft tunnel is gradually lowered, and treats that the value that baroceptor 321 is exported is less than reference voltage
When, relay is backed off, and electric magnet 312 quits work.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
