The shell 1 is formed by vertically connecting a main pipe and a branch pipe; the cross-sectional shapes of the main pipe and the branch pipes are both circular or square. The shell 1 is provided with a tuyere I, a tuyere II and a tuyere III. The driving executive component adopts an electric push rod, a hydraulic push rod or a hydraulic cylinder. The outer side wall of the shell is fixedly provided with a support 15, the driving executive component 7 is hinged on the support 15 on the outer side of the shell, and the end part of the driving executive component 7 is provided with a connecting fork head.
Two valve shafts 6 are respectively installed at the positions of the air port I and the air port II through bearings 14, the two valve shafts 6 are arranged in parallel, the plane where the two valve shafts 6 are located at the position of the air port I is perpendicular to the channel of the air port I, and the plane where the two valve shafts 6 are located at the position of the air port II is perpendicular to the channel of the air port II. Two limiting plates are arranged on the inner wall of the shell 1, the limiting plates are annular, and the two limiting plates are respectively arranged at the closing positions corresponding to the air inlet I and the air inlet II. One end of the valve shaft 6 extends out of the shell 1, a gear 5 is arranged at the end part of the valve shaft 6, the gears 5 on the two valve shafts 6 at the air inlet I are meshed, the gears on the two valve shafts 6 at the air inlet II are meshed, and the number of teeth of the two valve shafts 6 at the same air inlet is the same. Each valve shaft 6 is fixedly provided with a valve plate 9, the valve plates 9 are arranged in the shell 1, when the sections of the main pipe and the branch pipe are circular, the shape of each valve plate 9 is semicircular, and when the sections of the main pipe and the branch pipe are square, the shape of each valve plate 9 is square. When two valve plates at the same air port are positioned in the same plane, the air port can be blocked. The connecting fork 8 of the driving actuating piece 7 is hinged with a hinge lug on a valve shaft 6 at the air port I (or the air port II), and the hinge lug is arranged at one end of the valve shaft, which is provided with the gear. The valve shaft 6 can be driven to rotate, and the other valve shaft at the air port I (or the air port II) is connected with the valve shaft at the air port II (or the air port I) through a transmission mechanism; and a limiting deflector rod 4 is arranged on the other valve shaft at the air port II (or the air port I).
The transmission mechanism adopts a crank and rocker mechanism and comprises a crank 10, a connecting rod 12 and a rocker; the crank 10 is arranged at the gear end of the other valve shaft at the air port I (or the air port II), and the rocker is arranged on the valve shaft at the air port II (or the air port I); the crank 10 is connected to the rocker by a connecting rod 12. The crank and the hinge lug are respectively arranged on the two valve shafts at the air port I (or the air port II); and the limiting deflector rod 4 and the rocker are respectively arranged on two valve shafts at the air opening II (or the air opening I). The limit switch mounting plate 2 is arranged close to the valve shaft provided with the limit deflector rod 4, the limit switch mounting plate 2 is arranged on the outer side wall of the shell, and the limit switch mounting plate 2 is provided with two limit switches 3; the two limit switches 3 are respectively positioned at two sides of the limit deflector rod 4. The collision heads of the two limit switches 3 face the limit deflector rod 4. The position of the limit switch in the sliding groove is adjusted, the deflection angle of the swing arm is changed, and the stroke of the electric executive part can be changed, so that the opening degree of the two air doors is changed, and the air flow of the two air doors is in a certain proportion. The limiting shift lever 4, the crank 10 and the hinge lug can also be arranged on the same valve shaft at the same time.
When the crank 10 is driven by the actuator 7, the valve shaft 6 and the valve plate 9 at the tuyere I are driven to rotate. At the same time, the gear 5 on its valve shaft 6 will also rotate. Since the gears on the two valve shafts 6 are paired and have the same number of teeth, the other gear also rotates in the same step and in the opposite direction. Therefore, the valve shaft and the valve plate at the air outlet II are driven to deflect in opposite rotating directions. When viewed from the direction of the arrow shown in the figure, one of the two valve plates at the same air inlet rotates clockwise around the valve shaft, and the other valve plate rotates anticlockwise around the valve shaft. Two limiting plates are arranged on the inner side wall of the shell 1, the two limiting plates respectively correspond to the closing positions of the two air ports, and when the valve plate 9 rotates to be blocked by the limiting plates, the air door is in a closing state. When the valve plate 9 rotates to be vertical to the limiting plate, the air opening is in a full open state. When the valve shaft and the valve plate at the right side air port (air port I) rotate, the motion is transmitted to the valve shaft and the valve plate at the front side air port (air port II) through the connecting rod 12. The valve shafts at the two air outlets and the valve plate have the same structure, so the generated movement is also the same. Because the two air ports are installed in a fully closed state and a fully opened state. Therefore, the two air ports can ensure that the two air doors are not closed at the same time and are not opened at the same time no matter how much the air ports act. Thus, the direction of the wind flow is changed, or the wind flow is proportional to the sizes of the two air doors.
