245 compress blade 9 from top and bottom, reduce the gap between blade 9, are able to carry out secondary seal to reach,
The effect of fire resisting damper leakproofness is improved, and the water inside water tank 191 can be evacuated to the inside of radiating sleeve 193 by micro pump 192
It radiates to 11 surface of transmission case, while blower 20 can be by the inside of external air injection transmission case 11 and water tank 191
It radiates, last hot-air is blown out from water inlet pipe 21, and use can be completed.
In conclusion the fire-fighting fire resisting damper, drives wind deflector 14 to rotate by transmission mechanism 16 by bull stick 12, and keep out the wind
The rotation of plate 14 then can be able to carry out secondary seal to have by sealing mechanism 24 to being sealed inside valve body 1, improve
The advantages of fire resisting damper leakproofness, solve existing fire resisting damper only by clamping mutual between each flabellum to flue gas and the intensity of a fire into
The phenomenon that row is primary to be stopped, and flabellum is easy to appear deformation after a period of time, the poor problem of leakproofness avoids and is easy to appear leakage
The case where cigarette, uses convenient for people.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
