Description
Technical field
The present invention relates to volume adjusting apparatus field, more particularly to a kind of gear drive volume damper.
Background technology
Volume damper is the folding angle by valve blade controls air force, by the folding angle for adjusting blade
Spend to control the size of air quantity, be industrial premises civil buildings ventilation, air adjustment and air purification engineering in it is indispensable
Tail end of central air conditioner accessory, air-conditioning is commonly used in, in air system plumbing, for adjusting the air quantity of branch pipe, it can also be used to new
Wind is adjusted with the mixing of return air.Gear drive volume damper has mechanical and two kinds of electric-controlled type, wherein, gear drive air quantity is adjusted
Section valve is mechanical a kind of, it is necessary to operating personnel rule of thumb twist worm screw to adjust the opening degree of blade.
But, the dismounting of existing gear drive volume damper is complex, is unfavorable for that blade is cleared up, it is easy to cause
Air pollution；And existing gear drive volume damper is in closure, by larger gas pressure, compressing blade turns
It is dynamic so that gas does not reach good using effect through the gap of blade.
The content of the invention
In view of this, the present invention provides a kind of gear drive volume damper, with the spy for being easy to clear up, be easy to use
Point.
The present invention is solved the above problems by following technological means：
Gear drive volume damper of the invention, including valve body and the regulation leaf in the air port of the valve body
Piece, one end of the power transmission shaft of the regulation blade is connected through the valve body and with the drive device of the valve outer surface, its
It is characterised by：Upper and lower both sides at the air port of the valve body are respectively articulated with the baffle plate for blocking the regulation blade, described
Valve body includes the ducted body and the closed shape at the opening of the ducted body of U-shaped, is offered out on the inside of the ducted body
Air holes, the center in the outside of the ducted body is provided with air inlet, and the drive device is installed on the closed shape.
Further, the drive device is worm and gear governor motion, and the power transmission shaft is fixedly connected with worm gear.
Further, the keying angle of the regulation blade is 90 °.
Further, one end top that the power transmission shaft is connected with the drive device is additionally provided with pointer.
Gear drive volume damper of the invention, the baffle plate being hinged can be rotated, when the flapper to
During the valve body level, the regulation blade can be blocked, it is also kept tight under by the compressing of larger gas pressure
Closed conjunction, with better seal effect；When the flapper is extremely vertical with the valve body, then can arbitrarily adjust described
Regulation blade, is easy to use；From the air inlet can to carrying out air blast in the ducted body, then from exhaust vent blowout,
The dust on the surface of the regulation blade can be blown off, be convenient to clean.
Brief description of the drawings
