Description
Technical field
This utility model relates to a kind of fire resisting damper, particularly to a kind of follow-on fire resisting damper.
Background technology
Fire resisting damper, normally opened, 70 DEG C or 280 DEG C closedowns, it is typically mounted at airduct and passes through at fire wall, play fire and turn off work
With, output electric signal can be set, valve closing when temperature is more than 70 DEG C or 280 DEG C, linkage send (benefit) blower fan to close.
Existing fire resisting damper is all to be connected lower valve by slat chain, and junction does not has spring structure yet, and intensity is low, fire resistance
Difference, is easily deformed, and inleakage is big.
Utility model content
This utility model provides a kind of follow-on fire resisting damper, is concave-convex by being provided with spring structure and blade, solves
Existing fire resisting damper junction does not has spring structure yet, and intensity is low, and fire resistance is poor, is easily deformed, the problem that inleakage is big.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of follow-on fire resisting damper of this utility model, including valve body, described valve body is welded by some blades, described blade
In concave-convex, the convex surface of described blade is provided with smoke discharging pipe, and described valve body top is provided with second cross beam, on described second cross beam
Being provided with valve, described valve body is provided with first crossbeam, and described first crossbeam is connected by connector and described valve body, described connection
Part and described valve body junction are provided with spring.
As a kind of optimal technical scheme of the present utility model, described connector is zigzag.
As a kind of optimal technical scheme of the present utility model, described valve is connected by the second bolt and described valve body top
Connect.
As a kind of optimal technical scheme of the present utility model, described connector upper end is connected by screw and described valve body
Connecing, described connector lower end is connected by the first bolt and described first crossbeam.
This utility model is reached to provide the benefit that: this utility model intensity is high, and fire resistance is strong, is unlikely to deform, does not turns round
Song, inleakage is few.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment
As Figure 1-3, this utility model provides a kind of follow-on fire resisting damper, including valve body 1, if valve body 1 is by cured leaf
Sheet 2 welds, and blade 2 is in concave-convex, and the convex surface of blade 2 is provided with smoke discharging pipe 5, and valve body 1 top is provided with second cross beam 6, and second
Crossbeam 6 is provided with valve 11, and valve body 1 is provided with first crossbeam 3, and first crossbeam 3 is connected by connector 4 and valve body 1, connector
4 and valve body 1 junction be provided with spring 7.
Connector 4, in zigzag, makes valve body 1 and first crossbeam 3 be completely embedded, preferably laminating valve body 1, appearance looks elegant.
Valve 11 is connected by the second bolt 10 and valve body 1 top, it is simple to installation and removal.
Connector 4 upper end is connected by screw 8 and valve body 1, and connector 4 lower end is connected by the first bolt 9 and first crossbeam 3
Connect, it is simple to installation and removal.
This utility model, intensity is high, and fire resistance is strong, is unlikely to deform, and non-warping, inleakage is few.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature
Carry out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
