[0002] The throttle mixing valve includes a valve body, a rotating shaft, a sector gear and a motor. During the assembly process, the sector gear needs to be installed on the valve body rotating shaft first, and then the auxiliary intermediate gear is installed. After the assembly is in place, the sector gear needs to be welded to the rotating shaft. Before that, it is necessary to test the operation of the product to see whether the motor in the valve body can drive the valve body rotating shaft to rotate. Since the sector gear has not been welded at this time, it is easy to jump out of the assembly. How to power on the assembled product and test its operation while pressing down the sector gear is a problem that needs to be solved. In addition, the product has requirements for the motor exit angle.

The protruding end of the mounting plate is provided with a welding avoidance opening opposite to the fan-shaped gear on the valve body. A number of concentrically distributed mounting seats are installed in an array around the avoidance opening. A cam follower is installed on the inside of the mounting seat. A pressure ring for pressing the valve body is provided below the avoidance opening.

[0007] Preferably, the power supply mechanism comprises a slide table cylinder mounted to the side end of the valve body positioning tool support plate, a lifting frame driven by the slide table cylinder to move up and down, a lifting block mounted to the lifting frame, and a probe inserted into the lifting block, the probe being opposite to the two terminals of the motor on the valve body, the probe being connected with the power supply, and a groove for avoiding the gear on the motor being formed in the middle of the lifting block.
