Description
Technical field
The utility model is related to firefighting security device technical field, in particular to sealing smoke exhaust fire damper.
Background technology
Smoke exhaust fire damper belongs to firefighting security device, is generally located in smoke discharging pipe, and usually in opening, fire occurs
During calamity, opened smoke-discharging can be automatically closed when flue-gas temperature reaches certain temperature in smoke discharging pipe, and full within a certain period of time
The requirement of sufficient inleakage and fire resisting integrity degree is risen every cigarette fireproofing function.
But current general smoke exhaust fire damper has between gap, blade and blade only less due to blade and outline border
The problem of part such as simply overlaps at the reasons, and blade leaks out when closing is more apparent, can not ensure compliance with associated safety requirement.
Utility model content
In order to solve the problem of existing smoke exhaust fire damper leak out it is obvious design it is more simple and crude, the utility model carries
For sealing smoke exhaust fire damper.
Smoke exhaust fire damper is sealed, including valve body, blade is installed on the valve body, the blade is connected with blade driving dress
It puts, the blade driving apparatus controllable blade folding is provided with supporting rack between the valve body and blade, blade lower end is cased with
Cutting ferrule sealing element.
Further, the cutting ferrule sealing element includes cutting ferrule and catch, and the catch is fixedly connected with cutting ferrule punching press.
Further, the cutting ferrule is socketed on blade bottom end, and the catch can block the gap between blade.
Further, blade junction is provided with sealing catch on support frame as described above.
Further, the sealing catch is in the arc prominent to direction blade.
Further, the cutting ferrule sealing element is made of stainless steel with sealing catch.
The utility model has the advantage of, sealing mechanism is correspondingly arranged at member slots, can effectively prevent leaking out, safety
Coefficient is high；And structure is more firm succinct, durability is good.

Specific embodiment
In order to solve the problem of existing smoke exhaust fire damper leak out it is obvious design it is more simple and crude, the utility model carries
For sealing smoke exhaust fire damper.
The purpose, technical scheme and advantage for making the utility model embodiment are clearer, below in conjunction with the utility model
Attached drawing in embodiment carries out the technical scheme in the embodiment of the utility model clear, complete description, it is clear that described
Embodiment be the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art obtain without making creative work belong to this
The range of utility model protection.
As shown in Figures 1 to 7, smoke exhaust fire damper is sealed, including valve body 1, blade 2, the leaf are installed on the valve body 1
Piece 2 is connected with blade driving apparatus 3,3 controllable blade of blade driving apparatus, 2 folding, between the valve body 1 and blade 2
Supporting rack 4 is provided with, 2 lower end of blade is cased with cutting ferrule sealing element.Cutting ferrule sealing element can be in the situation for not influencing 2 normal folding of blade
Gap is effectively blocked down, and reduction is leaked out.
The cutting ferrule sealing element includes cutting ferrule 51 and catch 52, and the catch 52 is fixedly connected with 51 punching press of cutting ferrule.Cutting ferrule
The structure of sealing element is simply efficient, and production difficulty is low.
The cutting ferrule 51 is socketed on 2 bottom end of blade, and the catch 52 can block the gap between blade 2.It will card during production
Set 51 docks fixation with 2 bottom end of blade and installation can be completed.
Sealing catch 6 is provided on support frame as described above 4 with 2 junction of blade.Sealing catch 6 can block blade 2 and support
Gap between frame 4 further prevents leaking out.
The sealing catch 6 is in the arc prominent to 2 direction of blade.The sealing catch 6 of arc is ensureing the same of leakproofness
When, frictional resistance during 2 folding of blade will not be increased.
The cutting ferrule sealing element is made of stainless steel with sealing catch 6.Stainless steel is firm corrosion-resistant, ensure that equipment performance
It can keep for a long time.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations, i.e., it is all to make equivalent changes and modifications according to the application range,
All should still it belong in the utility model covering scope.
