The operation principle and process for using of the present invention：Smoke exhaust fire damper, which is transported to, first needs position to be used, then
Smoke exhaust fire damper is installed on smoke discharging pipe by adjustable mounting plate 10, then 9 attaching plugs are inserted in power outlet, when flat
When use, the central rotational connecting shaft 2 inside smoke exhaust fire damper installation shell 1 is in the state of an opening, thus
It can be discharged fume with smoke exhaust fire damper, will be very high by the temperature of smoke exhaust fire damper flue gas then when fire occurs,
At this moment sealing the fusible link inside flabellum 3 will fuse under the action of high temperature, and then the circuit inside smoke exhaust fire damper will
Become on-state, then 6 will start to rotate, and at this moment start rotation 6 will drive driving wheel by motor output shaft 19
15 rotations, the driving wheel 15 of rotation will be rotated by the drive passing power wheel group 16 of belt, the passing power then rotated
Wheel group 16 will drive installation 1 manual pin hole 17 of shell rotation at this moment to turn to drive intermediate power wheel 14 to rotate by belt
Dynamic intermediate power wheel 14 drives the rotation in opposite directions of rotation connection wheel 18, the rotation connection wheel 18 at this moment rotated in opposite directions by frictional force
It is rotated with dynamic sealing flabellum 3 by central rotational connecting shaft 2, the sealing flabellum 3 at this moment rotated in opposite directions will be rotated into and be installed
The state of 1 internal vertical of shell, at this moment install shell 1 be internally provided with blend stop will stop installation shell 1 be rotated further, make
Flabellum 3 must be sealed and installation shell 1 keeps vertical state, so that sealing flabellum 3 is sealed installation shell 1, this
Sample is it is prevented that air enters scene of fire from smoke discharging pipe, so as to more preferably prevent fires, and on smoke exhaust fire damper
It is mounted with adjustable mounting plate 10, the bore of the smoke discharging pipe of traditional smoke exhaust fire damper installation is fixed, if smoke exhaust pipe
There is error and is difficult to install in the bore in road, and is mounted with adjustable mounting plate 10, adjustable mounting plate on smoke exhaust fire damper now
10 are made of installation mounting hole 30, interior flexible mounting plate 31, external extension sleeve-board 32, fastening nut 33 and U-shaped hole 34, first
Adjustable mounting plate 10 is welded on installation shell 1 by external extension sleeve-board 32, in this way when the bore of smoke discharging pipe with it is expected not
When the same, so that it may with by the relative position of expansion plate in adjusting and external extension sleeve-board 32, then smoke exhaust fire damper
Bore is adjusted to the size as the bore of existing smoke discharging pipe, is then fixed using fastening nut 33, is at this moment led to again
It crosses installation mounting hole 30 to be mounted on smoke discharging pipe smoke exhaust fire damper, so that smoke discharging pipe is adapted to different bores
Smoke discharging pipe, improves the diversity of smoke exhaust fire damper installation, so that it is even more to prevent fires in cigarette to install and use more convenient
3 both sides of sealing flabellum of valve are mounted with high temperature resistant hollow rubber strip 24, in the event of fire condition, are closed by sealing flabellum 3
When closing smoke exhaust fire damper, high temperature resistant hollow rubber strip 24 will make the sealing effect of smoke exhaust fire damper more preferable, to make
