Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a high-barrier fire damper comprises a valve body 1, valves 2 are mounted on two sides of the middle of the valve body 1 through rotating shafts, the valves 2 are used for blocking fire, bases are welded on two sides of the middle of the valve body 1 and distributed up and down, the rotating shafts are inserted between the bases on the two sides, a fixing base with a reset guide rod 4 is mounted on one side of the top of the valve body 1, the reset guide rod 4 is used for resetting the valves 2 from a closed state to be opened, a temperature fuse 11 (the temperature of the temperature fuse 11 is 280 ℃, the model number of the temperature fuse is RL 18) is arranged on one side of the inner wall of the valve body 1, the temperature fuse 11 is used for controlling the valves 2 to be closed, a control rod 3 is arranged between the two valves 2, the control rod 3 is used for controlling the two valves 2 to be opened and closed synchronously, linkage rods are fixedly mounted at two ends of the control rod 3, valve body 1's both sides inner wall all embeds there is movable sealing strip 5 (rectangular platelike structure), sealing strip 5's effect carries out edge seal to valve 2, slot 51 has been seted up to the centre of sealing strip 5, and sealing strip 5's both ends all weld fixing base 52 that is "U" type, the drive gear 6 of built-in temperature sensor (model Pt 100) is all installed through the drive shaft to one side of fixing base 52's both sides inner wall, drive gear 6 is for driving fixing base 52 and remove, thereby drive sealing strip 5 and remove the regulation, the one end of drive shaft still is provided with driving motor, limiting plate 12 has been welded between the inner wall of valve body 1, fixed plate 13 has been welded to one side of limiting plate 12, the aim at of fixed plate 13 is led spacing to fixing base 52, fixing base 52 slides through drive gear 6.
