Description
Technical field
The present invention relates to a kind of fire resisting damper more particularly to a kind of executing agencies of fire resisting damper.
Background technique
Fire resisting damper refer to be mounted on ventilation, air-conditioning system is sent, on return air duct, usually in open state, when in pipeline
Closing when flue-gas temperature reaches 70 DEG C, meets fire stability and fire integrity demands within a certain period of time, rises every cigarette back-fire relief
The valve of effect.
Most of fire resisting damper Full-automatic mechanisms are all by the lasting energization of motor to maintain opening for valve currently on the market
It opens and closes, motor loads the energization i.e. serious waste energy for a long time and the damage of motor is also be easy to cause to make failure mechanisms.City
Most of fire resisting damper Full-automatic mechanisms cannot close valve in fuse blows moment on field, there is the delay of long period.
Chinese patent 200620106001.5 is able to achieve smoke evacuation and fireproof function.Structure designed by the patent makes
Unify an accessory assembly therefor with also needing to match in the middle, convenient for the execution to fire resisting damper valve opening and closing function, the accessory assembly therefor includes
One piece of mounting plate, be rotatably assorted on mounting plate a rocker arm, and one end connects the wirerope of executing agency, and the rocker arm other end is ined succession
Reset spring connects the blade main shaft of fire resisting damper at rocker arm central rotational, and executing agency can drive rocker arm to rotate through wirerope, from
And the swing of control valve blade.It needs to close or Open valve passes through manual control, operation is not convenient enough, fiery when occurring
When calamity, fire could not be found at the first time, cannot close valve in time, there are some potential safety problemss.In addition, above-mentioned execution
Mechanism cooperates corresponding accessory assembly therefor to cannot achieve the function that temperature control valve acts.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a kind of executing agencies of fire resisting damper.
A kind of executing agency of fire resisting damper, including manual driving member, fusing driving part and electrical components；
