A pointer provided with two magnetic steels is installed on the motor shaft, and a magnetic steel gear is also arranged on the reduction gear box directly below the motor. When the motor rotates, the magnetic transmission gear on the gear box is driven to rotate through the magnetic transmission, and then the gear set is reduced to increase the torque to drive the valve stem ball core connected therewith to rotate, thereby implementing the function of controlling the opening and closing of the valve. However, in actual production, this structure has some problems affecting the production speed and product quality. Figure 1 As shown in the figure, in the process of assembling the electronic module assembly to the valve control base meter assembly, when the motor magnetic pointer on the electronic module assembly approaches the magnetic transmission tooth on the gear box, part of the magnetic transmission tooth is attracted to the magnetic pointer on the motor and is separated from the gear shaft. When continuing to install downward, the tooth hole cannot be accurately and quickly aligned with the shaft center, affecting the assembly speed. Moreover, in the process of downward extrusion, the magnetic transmission tooth or the gear shaft is easily damaged, causing product quality hazards. At the same time, in the process of upward attraction of the magnetic transmission tooth, the tooth cooperating with it is disengaged, and in the process of assembly from top to bottom again, due to the blocked view, it cannot be visually inspected, and the defect that the bottom of the magnetic transmission tooth presses the upper end surface of the cooperating tooth cannot be normally engaged.
