As the improvement of such scheme, the controller is motor-driven controller.
As the improvement of such scheme, the controller is provided with recoil simulator, and the recoil simulator is connected with fire-fighting center.
Compared with prior art, the beneficial effects of the utility model are：
1st, a kind of compound automatic fireproof valve provided by the utility model, including valve body, cross on valve body sharf, set
The blade in sharf, the first heat detector for being arranged in valve body and the second heat detector are put, is arranged on the outside of valve body and and blade
The controller of axis connection.During fire, gas temperature is measured by the first heat detector, when survey of the gas temperature more than the first heat detector
When measuring limit value, controller closes blade, plays a part of every cigarette back-fire relief；When discharging fume exhaust, pass through the second heat detector and measure gas
Temperature, when measurement limit value of the gas temperature more than the second heat detector, controller closes blade, prevents string fire, prevents discharge
High-temperature gas can ignite other regions combustible or burn nearby personnel.The compound automatic fireproof valve of the application, simple in construction,
It is stable performance, good every cigarette back-fire relief effect.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As depicted in figs. 1 and 2, present embodiments provide a kind of compound automatic fireproof valve, including valve body 1, cross at valve body 1
On sharf 2, the blade 3 being arranged on sharf 2, the first heat detector 4 for being arranged in valve body and the second heat detector 5, set
Put in the outside of valve body 1 and the controller 6 being connected with sharf 2.The controller 6 is motor-driven controller, the control
Device 6 is provided with recoil simulator 61, and the recoil simulator is connected with fire-fighting center.In the other embodiment of the application, the control
Device can also be the controller of manual actuation.The measurement limit value of first heat detector 4 is 70 DEG C, and the measurement limit value of the second heat detector is
280℃。
Specifically, as shown in figure 3, blade 3 is provided with sealing strip 31, when blade is closed downwards, blade and blade are strengthened
Between seal, make more preferable every cigarette back-fire relief effect.In addition, the blade surface is provided with magnesium oxide coating film, magnesium oxide coating
Film high temperature resistant, avoids blade from being deformed in high temperature.
Specifically, as shown in figure 4, valve body 1 is provided with copper sheathing 11, the sharf 2 is arranged in copper sheathing 11.In addition, sharf 2
Packing spring 21 is provided with the junction of valve body 1, strengthens the seal between blade and valve body, is made more preferable every cigarette back-fire relief effect.
The course of work of the present embodiment：During fire, gas temperature is measured by the first heat detector, when the temperature in pipeline surpasses
Cross 70 DEG C, i.e., more than the measurement limit value of the first heat detector when, controller close blade, play a part of every cigarette back-fire relief；Or control
Close, play a part of every cigarette back-fire relief centrally through DC24V power supplies blade.After sterilized, control centre passes through DC24V
Power supply blade is opened, and plays a part of smoke evacuation exhaust.When discharging fume exhaust, gas temperature is measured by the second heat detector,
When the temperature in pipeline is more than 280 DEG C, i.e., more than the measurement limit value of the second heat detector when, controller closes blade, prevents string fire,
