The utility model discloses kink at the blade sets up the recess, sets up the spring leaf at the groove, utilizes the deformable characteristic of spring leaf with blade and blade, blade and body seals, and the leakproofness is good, and the structure is exquisite.
Description
Technical field
This utility model is related to fire-fighting equipment field, more particularly, to a kind of fire resisting damper.
Background technology
Fire resisting damper is arranged in fire-fighting smoke exhaust system and passage of central air conditioner system, and operation principle is to install using on valve
Pole fusible alloy temperature control, using the effect of action of gravity and spring mechanism, when fire occurs, flame enters blepharoptosis
Road, high temperature makes the fusible alloy on valve melt, or makes memorial alloy produce deformation to make valve be automatically switched off, for air channel with anti-
The occasion that fiery subregion runs through.
Between existing fireproof valve blade and blade, between blade and valve body, only connection, sealing are firmly contacted by blade
Poor, how to design a kind of fire resisting damper of good seal performance becomes technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of fire resisting damper, thus solving foregoing problems present in prior art.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of fire resisting damper, including：One valve body；
Be arranged on several blades be rotatably connected in valve body with valve body；The two ends of blade are provided with kink, and kink has recessed
