Description
Technical Field
The utility model relates to an air valve technical field specifically is a novel roll up curtain formula air valve.
Background
The air valve is a device for adjusting the size of air flow in a ventilation pipeline system, and can adjust the size of a ventilation opening according to the requirement of the ventilation pipeline system so as to control the air flow in the ventilation system, and has a function of lifting the weight in the ventilation pipeline system. The existing common air valve is a louver air valve, and the air quantity is controlled by the rotation angle of a louver. The disadvantages of such dampers are: as the louver gaps can not be completely closed and the number of blades is large, the sealing performance after closing is poor; because the air flow passes through both sides of the louver, the requirement on the bending resistance of the structure is high, and the material selection cost is high; and the air flow regulation precision of the louvered air valve is insufficient, so that the ventilation quantity is uncertain, and particularly in the field of deodorization, the louvered air valve cannot well adapt to frequent regulation operation and cannot meet the requirements of a system.
For example, chinese patent CN211649106U proposes a rolling shutter type air valve, which drives the rotation direction of the driving shaft through a motor, and realizes the adjustment of the rotation direction of the driven shaft under the driving of a chain, thereby realizing the unfolding and folding of the rolling shutter, and correspondingly closing and opening the ventilation opening, but also has the problems of insufficient adjustment precision and incapability of fine adjustment of the air volume.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel roll up curtain formula blast gate to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a novel roll up curtain formula blast gate, includes the blast gate main part, be equipped with square vent in the blast gate main part, still be equipped with chain drive mechanism, roll up curtain jack, sealing mechanism in the blast gate main part, roll up curtain jack and include that driving shaft, driven shaft, one end are convoluteed at the epaxial first stay cord of rolling up of driving and one end are convoluteed on the driven shaft, the other end of first roll of curtain is provided with the dead lever, the stay cord even with the dead lever is connected, be provided with fine tuning on the dead lever, fine tuning including fix the second motor on the dead lever, connect in lead screw, threaded connection that the output of second motor is even in movable rod on the lead screw, be connected with the second between dead lever and the movable rod and roll up the curtain, still be connected with the telescopic link between dead lever and the movable rod.
The second roller shutter is positioned below the telescopic rod and the screw rod.
The chain driving mechanism comprises a first motor for driving the driving shaft to rotate and a chain annularly arranged between the driving shaft and the driven shaft.
The sealing mechanism adopts a rubber sealing gasket.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is:
the utility model discloses a set up roll curtain jack, drive first roll curtain through chain drive mechanism and remove, make first roll curtain expand and receive to realize the closure of vent and open, and through setting up fine-tuning, can finely tune the amount of wind, improved air regulation's precision.
