Description
Technical field
The utility model relates to the constructure ventilation field, specifically is a kind of electric actuator of volume damper of ventilation duct.
Background technique
Volume damper generally all is installed in the ventilation duct of tall building.Volume damper comprise blade, with fixing main shaft and the actuator of blade.Actuator can drive main shaft rotation, and then drives blade rotation, and the angle (abbreviation blade angle) that changes blade and ventilation duct is with the purpose of the air output size that reaches regulation valve body.Because the actuator position is higher, inconvenient manually-operable is so generally be to adopt electronic actuator.But the actuator of prior art adopts switch control, this actuator can only open and close between two states at valve body switches, that is to say that it is 0 degree or 90 degree that blade angle can only fix, blade can't 0 ~ 90 the degree between any angle start and stop, so air output can only or be closed fully in this two states and select in maximum, can't adjust air output placed in the middle, nature can not satisfy the needs that people arbitrarily regulate the air output size.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of electric actuator that can arbitrarily regulate the volume damper of air output size is provided.
Technical solution of the present utility model is, a kind of electric actuator with volume damper of following structure is provided, it comprises support and the main shaft of fixing with blade, be fixed with motor on the support, it also comprises circuit board, multi-stage speed-reducing gear and the axle sleeve of fixing with main shaft, axle sleeve rotatably is engaged on the support, be fixed with driving gear on the axle sleeve, a plurality of rotating shafts of circuit board and multi-stage speed-reducing gear all are fixed on the support, primary speed-down gear engagement in the output gear of motor and the multi-stage speed-reducing gear, the final reduction gear of multi-stage speed-reducing gear and driving gear engagement, also be fixed with external gear on the axle sleeve, the angle acquisition gear is installed, angle acquisition gear and external gear engagement on the circuit board.
The working principle of the electric actuator of this volume damper is: the computer with the control room is inputted an external control signal such as voltage signal or current signal to circuit board, circuit board control power switch is opened, motor rotates, and pass through successively the motor output gear, multi-stage speed-reducing gear and driving gear transmission, so that axle sleeve rotates, the final main shaft that drives rotates to change blade angle, simultaneously, also begin to rotate with the angle acquisition gear of the external gear of axle sleeve engagement, circuit board can generate the feedback signal that can react the main shaft rotation angle according to the rotation angle of angle acquisition gear, when this feedback signal equates with external control signal, circuit board disconnects power supply, motor stops operating, and blade stops operating.
After adopting above structure, the electric actuator of the utility model volume damper compared with prior art has the following advantages:
This electric actuator energy is so that any angle start and stop of the blade of volume damper between 0 ~ 90 degree, so just realized the adjusting of air output maximum and air output any one air output placed in the middle between closing, so just guaranteed that people arbitrarily regulate the air output size as required.
As preferably, driving gear is tooth sector, because the amplitude of fluctuation of driving gear can not surpass 90 degree, so select tooth sector can reduce the volume of whole electric actuator, be convenient to install.
