[0026] A proportional valve of a motor rotor structure, such as Figure 1-Figure 4 As shown, it includes a conveying pipeline 1 and a connecting shell 2 arranged above the conveying pipeline 1. A stator 8 is fixedly arranged inside the connecting shell 2 through a fixed bracket. A rotor 12 is rotatably arranged inside the stator 8. One end of the rotor 12 extends into the conveying pipeline 1. A rotating pointer 4 is fixedly arranged at one end of the rotor 12 away from the conveying pipeline 1. The rotating pointer 4 is located above the connecting shell 2. By arranging the stator 8 inside the connecting shell 2, the user can generate a magnetic field inside the stator 8 after energizing the stator 8, so that the rotor 12 located inside the stator 8 can rotate using the magnetic field generated by the stator 8, and then the lower half of the rotor 12 can rotate inside the conveying pipeline 1, so that the rotor 12 can accurately control the opening and closing of the valve inside the conveying pipeline 1 to control the amount of water passing through.

The threaded connection groove 13 is internally threadedly screwed with a fastening bolt 10, and the threaded connection seat 11 is threadedly screwed with the fixed connection seat 9 through the fastening bolt 10; by providing the threaded connection groove 13 on the fixed connection seat 9 and the threaded connection seat 11, the fastening bolt 10 screwed with the internal thread of the threaded connection groove 13 can be threadedly screwed with the fixed connection seat 9, so that the two can be connected or disassembled, so that the user can disassemble, repair or maintain the driving part above the conveying pipeline 1;

[0028] Among them; the lower half of the rotor 12 passes through the threaded connection seat 11 and the fixed connection seat 9 and extends to the inside of the conveying pipe 1, and the lower half of the rotor 12 is rotatably connected to the threaded connection seat 11. By rotatably connecting the lower half of the rotor 12 to the threaded connection seat 11, the threaded connection seat 11 can be disassembled together after the driving part is disassembled. At the same time, the lower half of the rotor 12 does not contact the rotating groove opened in the middle part of the fixed connection seat 9, so that the lower half of the rotor 12 can be separated from the fixed connection seat 9 after being separated from the conveying pipe 1, so that the driving part can be disassembled.
