[0029] Among them, the fixing mechanism 5 includes an installation shell 51, a guide groove 52, an extrusion block 53 and an anti-slip pattern 57.

[0030] The working principle of the utility model is as follows:

[0031] The stop valve 6 is placed on the mounting housing 51, and then the operation of the second motor 121 is controlled by the single chip microcomputer 8. The output shaft of the second motor 121 drives the rotating shaft 124 and the worm 122 on the rotating shaft 124 to rotate, and the worm 122 meshes and rotates with the worm wheel 123, thereby driving the rotating shaft 58 to rotate, and the rotating shaft 58 drives the rotating disk 54 to rotate through the bearing. The rotation of the rotating disk 54 drives the rotating shaft 55 to both rotate and slide in the guide groove 56, and the guide groove 56 gradually moves toward the central axis direction of the rotating shaft 58, thereby driving the extrusion block 53 to slide and avoid in the guide groove 52, and then the extrusion block 53 moves toward the center of the turntable 54 until the anti-skid pattern 57 on the extrusion block 53 is in contact with the stop valve 6 and fixed. Therefore, by controlling the rotation speed of the second motor 121, the clamping force of the extrusion block 53 on the stop valve 6 can be flexibly adjusted, so that electric stop valves of different sizes can be accurately fixed, thereby improving the flexibility and efficiency of precision adjustment;

[0032] After the fixation is completed, the operation is regulated by the single chip microcomputer 8, and the output shaft of the motor 1 drives the screw 17 to rotate. The screw 17 is connected to the left end of the mounting plate 11 through a thread, and then the mounting plate 11 slides on the inner wall of the slide groove 3 and moves downward, and at the same time drives the right end of the mounting plate 11 to slide on the outer surface of the support 16 and move downward together until the rubber head contacts the upper surface of the stop valve 6. The rubber head may be elastic and can effectively contact the surface of the stop valve 6 and provide a stable support. When the rubber head contacts the stop valve 6, the spring 15 starts to work. The expansion and contraction of the spring 15 will drive the sliding column 9 to slide upward. When the sliding column 9 is pushed upward by the spring, it will enter the sliding hole 10 to elastically fix the top of the stop valve 6 to prevent shaking during adjustment.

[0033] Then, the motion trajectory threshold of the photoelectric sensor 14 and the initial position of the valve is set, and then the operation of the stop valve 6 is regulated by the single chip microcomputer 8 to slowly open the valve. On the valve motion trajectory, a suitable threshold is set as the motion threshold between the initial position and the current position of the valve. The photoelectric sensor 14 can monitor the valve position and trigger the control signal of the single chip microcomputer 8 when the threshold is reached. When the photoelectric sensor 14 detects that the valve position reaches the threshold, the single chip microcomputer 8 can send a control signal according to the preset program and regulate the operation of the timer 4 to start recording the movement time of the valve from the initial position to the current position. When the valve rotates to the maximum angle, the photoelectric sensor 14 will convey the rotation time between the initial position and the current position of the valve to the single chip microcomputer 8. The single chip microcomputer 8 converts and transmits this data to the connected timer 4 for recording and calculating the opening speed of the valve. If the opening and closing speed of the valve is too slow, it may cause energy waste and a decrease in the system response speed. Through adjustment and optimization, it can be improved to improve the performance and efficiency of the electric stop valve, thereby helping to adjust and optimize the performance of the electric stop valve, improve the energy efficiency and response speed of the electric stop valve, and enhance the stability and reliability of the electric stop valve.

[0034] It is worth noting that the specific model of the single chip microcomputer 8 disclosed in the above embodiment is S7-200, and it is recommended to use D180M-0160030B-E for motor 1 and motor 121, PS-220 for timer 4, and CPK-TR40MR3 for photoelectric sensor 14. The single chip microcomputer 8 controls the operation of motor 1, motor 2 121, timer 4 and photoelectric sensor 14 using methods commonly used in the prior art.
