Description
Technical field
It the utility model is related to fire-fighting smoke controlling technical field, more particularly to a kind of fire resisting damper of band sealing reed.
Background technology
Prior art fire resisting damper is to ensure air-tightness using simple between blade, rigid mutually overlap joint, but due to material
The reasons such as material, manufacture craft, environment, blade and valve body is caused always to have more or less deformation.Due to being rigid overlap joint, slightly become
Shape, poor sealing when will cause the fire resisting damper to close, greatly weaken fire resisting damper and prevent what flue gas was stretched along airduct pipeline
Effect, fire is easily caused to be spread along airduct pipeline, so as to cause serious harm.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of fire resisting damper of band sealing reed, with
The air-tightness of fire resisting damper is effectively improved, so as to ensure that fire resisting damper prevents the effect stretched along airduct pipeline of flue gas.
The purpose of this utility model is achieved by the following technical programs：
A kind of fire resisting damper of band sealing reed provided by the utility model, including valve body, blade, sharf, support, axle
Set, postive stop baffle, executing agency, heat detector, linkage；The support is arranged on the inwall of valve body both sides, the axle sleeve
It is arranged on support；The blade is arranged on sharf and forms valve block component, and the parallel equidistant arrangement of valve block component exists
In valve body, the edge of its adjacent blades can be overlapped mutually, in the rack-mount axle sleeve in the both ends of its sharf；It is described spacing
Baffle plate is arranged on the inwall of valve body upper and lower ends, and blade adjacent thereto can be overlapped on postive stop baffle；The heat detector with
Executing agency connects；The executing agency connects control sharf by linkage；In addition, between the blade, each blade
Edge in the same direction, runner sealing reed is provided with its faying surface.
The utility model on the mutual faying surface of blade by setting runner sealing reed so that between blade
It is rigidly connected and is changed into being flexibly connected, meanwhile, this also increases the thickness of blade lap-joint, so as to also compensate for deformable blade institute
Caused space, effectively increase the air-tightness of fire resisting damper.
In such scheme, for the same sealing improved between blade and postive stop baffle, limiting block described in the utility model
Guard seal reed is provided with the faying surface of plate.
Further, the setting of the utility model runner sealing reed, guard seal reed can take following concrete measure：
Blade edge in the same direction is provided with S type blade bank bars, and the runner sealing reed is in the S types blade bank bar.
S type baffle plate bank bars are provided with the postive stop baffle, the guard seal reed is in the S types baffle plate bank bar.
Further, the sealing between raising blade and support, the end edge and support of blade described in the utility model
Between be provided with support sealing reed.Specifically, the support sealing reed can be with the U-shaped surface for being enclosed on support.
The utility model has the advantages that：
The utility model is by sealing the setting of reed so that each lap-joint of fire resisting damper from be rigidly connected be changed into it is flexible even
Connect, while also compensate for caused by deformable blade between space, including blade, between blade and postive stop baffle and blade
Space between support, the sealing of fire resisting damper is effectively increased, so that it is guaranteed that flue gas will not stretch along airduct pipeline.

Embodiment
Fig. 1~Fig. 5 show a kind of embodiment of the fire resisting damper of band sealing reed of the utility model, including valve body 1, blade
2nd, sharf 3, support 4, axle sleeve 5, postive stop baffle 6, executing agency 7, heat detector 8, linkage 9, spring 10.
As shown in figure 1, blade 2 is arranged on sharf 3 and forms valve block component, the parallel equidistant arrangement of valve block component is in valve
In body 1, the edge of its adjacent blades 2 can be overlapped mutually.As shown in figure 4, the edge in the same direction of blade 2 is provided with S type blade banks
Bar 11, it is embedded with runner sealing reed 12.So, runner sealing reed 12 has been arranged on the faying surface at the edge of blade 2,
Add the thickness of the lap-joint of blade 2.
As shown in figure 5, support 4 is arranged on the inwall of the both sides of valve body 1, axle sleeve 5 is arranged on support 4.The two of sharf 3
End is arranged in the axle sleeve 5 on support 4.U-shaped support sealing spring is provided between the end edge of the surface of support 4 and blade 3
Piece 13.
As shown in figure 4, postive stop baffle 6 is arranged on the inwall of the upper and lower ends of valve body 1, blade 2 adjacent thereto can overlap
On postive stop baffle 6.S type baffle plate banks bar 14 is provided with postive stop baffle 6, it is embedded with guard seal reed 15, so as to keep off
