Description
Technical field
This utility model is related to valve, more particularly, to a kind of smoke exhaust fire damper.
Background technology
Smoke-exhaust fire system is widely used, and is directed to security against fire, the problem of energy-conserving and environment-protective also increasingly to project,
So proposing higher requirement to the air-tightness aspect of smoke-exhaust fire system, general smoke exhaust fire damper is all by Q235 iron plate
It is welded after processing and forming, actuator power transmission shaft is susceptible to kill with smoke exhaust fire damper blade junction and becomes rusty
Extremely, have impact on the structural strength of whole smoke-exhaust fire, and operating difficultiess, when in addition producing, to hope for success in technique except existing
Outside the good problem of the flatness of iron plate after type processing, also there is a problem of being also easy to produce thermal deformation because of welding processing, thus giving
The workman making product brings very big difficulty of processing, and inleakage does not reach national standard and requires.
Content of the invention
This utility model purpose is to provide a kind of smoke exhaust fire damper, solves above technical problem.
In order to realize above-mentioned technical purpose, reach above-mentioned technical requirements, this utility model be employed technical scheme comprise that：
A kind of smoke exhaust fire damper, including outer frame body；Described outer frame body is internally provided with support and heat detector, and outside is provided with extension spring group
Part and actuator；It is provided with power transmission shaft and shelves bar on described support and outer frame body；Described tension spring component and actuator

Close；It is characterized in that：It is provided with blinker on described blade；It is provided between described power transmission shaft and support and outer frame body
Set；It is provided with spring leaf between described blade and support and outer frame body.
As preferred technical scheme：It is additionally provided with slot rolling on described outer frame body.
As preferred technical scheme：Described blade includes central shaft；Described central shaft side is provided with the first leaf
Piece, opposite side is provided with the second blade.
As preferred technical scheme：Described blade is multiple uniform, between stagger arrangement, formation sealing surface.
As preferred technical scheme：Described blinker passes through press strip link on blade, and connected mode is riveting.
As preferred technical scheme：Described set is copper sheathing.
The beneficial effects of the utility model are：A kind of smoke exhaust fire damper, compared with traditional structure：It is provided with blade and keep out the wind
Piece；It is provided with set between power transmission shaft and support and outer frame body；It is provided with spring leaf between blade and support and outer frame body；Not only not
Power transmission shaft at kill and become rusty dead phenomenon occurs, and blade construction is stable, is not in play, good seal performance it is ensured that
Inleakage reaches standard and requires；Because when manufacturing, blade does not need using welding, so there is not thermal deformation.
