Embodiment Construction
[0042] Figure 1 to Figure 9 As shown, the rotary integrated valve in this embodiment includes a driving mechanism 1 , a base 3 , a valve plate assembly A and a detection component B. The driving mechanism 1 is used to provide power, such as a stepping motor or a servo motor. The driving mechanism 1 is fixed on the base 3 through a fastener 2 , and the valve plate assembly A is fixed on the base 3 through a fastener 6 . The driving mechanism 1 has an output shaft (motor shaft of a stepping motor or a servo motor) 22, and the valve plate assembly A has a rotating shaft 11. The output shaft 22 and the rotating shaft 11 are coaxial and connected by a shaft coupling 4. The driving mechanism 1 drives the rotating shaft 11 to rotate. The detection part B includes a part 5 with a notch 51 and a photoelectric detection element 7 installed on the rotating shaft 11. The initial position of the rotating shaft 11 and the position during the rotation are detected and calibrated through t...
