Specific embodiment
As shown in Figure 1, the present invention includes valve body 1, temperature inductor 2 and gas tank with pressure 3；The valve body 1 is opened for one end
Mouth and the internal structure in cavity, thimble spring 4 is equipped in the cavity of the valve body 1, is in the lower section of the thimble spring 4
Thimble 5 is set, and the thimble spring 4 is in compressive state.The lower end of the thimble 5 is pointed inclined-plane, is provided at pointed inclined-plane
Air guide chamber 9 guides air-flow to blow direction.
The 1 top side of valve body, which is connected to, closes window gas source 13, and the valve body 1 is connected to 13 opposite side of pass window gas source
Window pneumatic circuit 11 is closed, hole system of the window gas across thimble 5 and thimble spring 4 is closed and is provided needed for closing window to pneumatic window opener
Gas.The 1 lower part side of valve body is connected to windowing gas source 12, and the lower part of the valve body 1 and windowing gas source 12 flank windowing relatively
Pneumatic circuit 10.
The temperature inductor 2 is a glass tube of the inside filled with the rapid expanding liquid that is heated, the glass tube lower part
Equipped with the positioning pin 6 for being inserted into 1 inside of valve body and the fixed thimble 5, the positioning pin 6 is set with 5 contact position of thimble
There is latch spring 7；The positioning pin 6 enables the thimble spring 4 be in compressive state.The glass tube is in environment temperature >=180
DEG C when split due to swelling rapidly because inside fills gas and refers to, the top of the positioning pin 6 is equipped with one end and is fixed on the valve body 1
Baffle 8, the baffle 8 enables the latch spring 7 be in compressive state being used to fix thimble 5 inside the valve body 1.It is described
The tank mouth of gas tank 3 with pressure is connected to the opening of the valve body 1, and the tank mouth is covered with sealing diaphragm, and the sealing diaphragm can
It is punctured by thimble 5, filled with carbon dioxide inside the gas tank 3 with pressure.
Under normal circumstances, windowing 12 air inlet of gas source enters windowing pneumatic circuit 10 in pneumatic window opener after passing through valve body 1
Supply opened skylight；It is interior for air to close to pneumatic window opener across the laggard window pneumatic circuit 11 of entering the GATT of valve body 1 to close 13 air inlet of window gas source
Close skylight.
When fire occurs or powers off because of accident, the glass tube of inductor 2 of the present invention reaches 180 DEG C in interior of building temperature
It is burst at~185 DEG C, positioning pin 6 bounces rapidly top by the effect of 7 elastic force of latch spring and releases to baffle 8 to thimble 5 at this time
Limitation, thimble 5 bounces rapidly under the effect of 4 elastic force of thimble spring and punctures the sealing diaphragm of 3 nozzle of gas tank with pressure, gas tank with pressure
Gas in 3 is passed through pneumatic window opener after entering windowing pneumatic circuit 10 by 5 bottom tip air guide chamber 9 of thimble, opens a window motor-driven
Make opening skylight and is aerated smoke evacuation.
Pneumatic system is not installed on skylight by many skylight producers at home, is all manually or electrically, about fire-fighting side
Face is linked with security against fire office, and when fire occurs, security against fire office could open to a feedback signal, if because of it
He causes fire-fighting signal to be interrupted at reason, or when power-off, fire control smoke exhausting function is just cannot be achieved in skylight, and to this security risk, we are pushed away
A pneumatic emergency valve of thermal sensation being used cooperatively with air-leg realizes fire control smoke exhausting function out.This emergency valve is to work as Indoor Temperature
Degree is when reaching 180 °, and the liquid expansion in inductor rises by inductor broken, and the movement of inductor latch spring pops up bolt, wink
Between firing pin spring act, striker pop-up crash through pressure carbon dioxide tank gas tank i.e. with pressure, striker end position is one, inclined-plane band
Areola, that is, air guide chamber, the carbon dioxide gas release of gas tank with pressure, the pressure of gas tank with pressure are enough to open push rod.Of the invention
Feature is: when temperature reaches 180 ° after fire generation, can come opened skylight, safety coefficient not against electronic and fire-fighting link
It is high.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
