[0002] A multi-channel rotary valve, also known as a rotary valve, a distribution valve, or a switching valve, is a valve that can simultaneously open or close multiple pipelines. It mainly uses a stepper motor in the valve body to drive the rotor to rotate to achieve the switching of fluid pathways. This design allows different fluid channels to be connected or disconnected, thereby achieving control over multiple fluid channels.

[0003] The existing multi-channel rotary cutting valve is widely used in many fields, especially in the field of experimental detection. With the advantages of multi-channel design, it can detect multiple sets of experimental data at one time, thus far exceeding the single-channel detection instrument in terms of work efficiency.

[0004] However, after the detection task is completed, in order to ensure the accuracy of the next experimental data, the multi-channel rotary cut valve must be thoroughly cleaned. The usual practice is to clean the pipes by sucking clean water, but considering that the pipes and the holes of the multi-channel rotary cut valve are connected by threads, in order to avoid bacterial growth, it is necessary to disassemble it for careful cleaning.

[0028] When the external drive board of the rotary valve is powered on, it relies on the optical coupling sensor to find zero and reset. According to the position to be reached, the motor drives the action to drive the reduction mechanism to rotate. When the rotor seat cooperates with the planetary carrier, the rotor seat rotates, thereby driving the upper rotor body to rotate, and then connecting the different threaded holes on the valve head, and finally achieving the purpose of switching different flow channels of the rotary cutting valve; A circle of threaded holes are arranged around the valve head 17, and the specifications of the threaded holes include but are not limited to 10-32UNF, 1 / 4-28UNF, etc. A small through hole is opened on the side for draining and balancing pressure.

Since the movable plate 58 is provided on the moving ring 54, the limiting ring 56 will drive multiple brush rods 6 to move horizontally.

[0030] When using the present device, first, after the use of the body 1 is completed, the hose 2 can be disassembled first. At the beginning, the hose 2 will be stuck by the ball 9 due to the annular groove 8. At this time, you only need to pull the pull plate 42 to drive the slider 48 to slide inside the slide groove 410, and the slider 48 will drive the moving cylinder 43 to move. The inner wall of the moving cylinder 43 will squeeze the spring 46, and the arc ring on the inner wall of the moving cylinder 43 will not squeeze the ball 9.

[0031] When the inside of the connecting groove 7 needs to be cleaned, it is necessary to pull the moving ring 54 to move. The moving ring 54 will drive the movable plate 58 to move horizontally. The movable plate 58 will drive the limiting ring 56 to slide on the outer surface of the light rod 59. At the same time, the limiting ring 56 drives multiple brush rods 6 to slide on the outer surfaces of multiple light rods 59, and pass through the rotating ring 55 to enter the inside of the connecting groove 7. The brush of the brush rod 6 fits inside the connecting groove 7. The rotating outer gear ring 52 will drive the multiple inner gear rings 53 meshing on the inside to rotate. The inner gear ring 53 not only drives the corresponding brush rods 6 to rotate on the inner wall of the connecting groove 7 through the multiple light rods 59, but also makes the brush rod 6 rotate on the inner wall of the connecting groove 7, which can better clean stains. Example 2: Please refer to Fig.10 The present invention provides a technical solution: a counterweight block 10 is arranged on the side of the sealing disk 57, and the counterweight block 10 is movably arranged at the end face of the rotating ring 55.
