The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the energy-saving air volume adjusting valve disclosed by the utility model comprises an adjusting valve housing 1, wherein a fixed frame 2 is detachably connected to the inner side wall of the adjusting valve housing 1 through uniformly arranged screws, so that the fixed frame 2 can be detached for replacement or maintenance. Two first adjusting blades 31 and two second adjusting blades 32 are respectively rotatably connected to the inside of the fixed frame 2 through a rotating shaft, the first adjusting blades 31 and the second adjusting blades 32 are arranged at intervals along the length direction of the fixed frame 2, and rotating gaps are reserved between the two adjacent first adjusting blades 31 and the second adjusting blades 32 and between the first adjusting blades 31 and the second adjusting blades 32 and the inner side wall of the fixed frame 2. The width of the first regulating blade 31 is greater than that of the second regulating blade 32, and a first driving assembly and a second driving assembly for controlling the first regulating blade 31 and the second regulating blade 32 are respectively arranged on the outer side wall of the regulating valve housing 1. The outer side wall of the regulating valve shell 1 is provided with a control box 6, a controller is arranged in the control box 6, and the controller is an NE040S controller. And one end of the regulating valve shell 1 close to the air inlet is provided with an air volume sensor 61, and the air volume sensor 61 is in signal connection with the controller.
The first drive assembly comprises a first drive motor 41, two first connecting shafts, two synchronizing wheels 42 and a toothed belt 43. The one end of two first connecting axles passes through the coaxial fixed connection of shaft coupling with the axis of rotation that first adjusting blade 31 corresponds respectively, through the coupling joint, conveniently unpacks the axis of rotation apart with first connecting axle to the dismantlement of the fixed frame 2 of convenience. The other ends of the two first connecting shafts extend out of the regulating valve shell 1 and are respectively and fixedly connected with the two synchronizing wheels 42 in a coaxial mode, and the toothed belt 43 is matched with the synchronizing wheels 42. The first driving motor 41 is fixedly arranged on the outer side wall of the regulating valve housing 1, an output shaft of the first driving motor 41 is coaxially and fixedly connected with one of the synchronizing wheels 42, and the first driving motor 41 is electrically connected with the controller.
The second drive assembly comprises a second drive motor 51, one first gear 52, two second connecting shafts and two second gears 53. The second driving motor 51 is fixedly arranged on the outer side wall of the regulating valve shell 1 opposite to the first driving motor 41, and the output shaft of the second driving motor 51 is coaxially and fixedly connected with the first gear 52.
