The sleeve magnetic attraction component 23 includes a positioning sleeve arranged on the rotating plate 22. 231, and an electromagnetic ring 232 arranged in the positioning sleeve 231, a plurality of first sealing components 18 and second sealing components 19 are arranged in the valve body 10, the first sealing component 18 is used to increase the sealing performance of the valve body 10 when the first gate plate 14 moves, and the second sealing component 19 is used to increase the sealing performance of the valve body 10 when the second gate plate 15 moves, the first sealing component 18 includes a first rubber ring 181 and a second rubber ring 182 embedded in the valve body 10 and sleeved on the outside of the first gate plate 14, the first rubber ring 181 is located at the upper part of the first flow channel 12, the second rubber ring 182 is located at the lower part of the first flow channel 12, and the second sealing component 19 has the same structure as the first sealing component 18.

[0041] It should be noted that, in the present embodiment, when the valve is in use, the vertical pressure-applying component 16 applies vertical downward pressure to the first gate plate 14 and the second gate plate 15, so as to seal the two ends of the first flow channel 12 and the second flow channel 13, so that the valve body 10 is in a closed state. At this time, the valve body 10 cannot enter the liquid. The corresponding first gate plate 14 and the second gate plate 15 are opened according to the passage requirements. When the passage is constructed, one inlet may correspond to one or more outlets, or multiple outlets may correspond to one or more inlets. When the valve is opened, the first gate plate 14 at the corresponding inlet and outlet is moved up to open. If the inlet and outlet are separated by the second flow channel 13, the second gate plate 15 corresponding to the second flow channel 13 is opened. If the second flow channel 13 is not separated between the inlet and outlet, the second gate 15 will not be opened. When the gate is opened, the controller triggers the sleeve magnetic attraction component 23 corresponding to the first iron cable 24 and the second iron cable 25 to be pulled according to the setting of the passage construction. At this time, the sleeve magnetic attraction component 23 magnetically fixes the first iron cable 24 and the second iron cable 25. After the rotating component 21 works, the sleeve magnetic attraction component 23 drives the first iron cable 24 and the second iron cable 25 to move, so as to drive the first gate 14 and the second gate 15 to move upward. When the hole on the first gate 14 coincides with the first flow channel 12, it means that the first gate 14 is opened. When the hole on the second gate 15 coincides with the second flow channel 13, it means that the second gate 15 is opened.

[0042] Furthermore, when the vertical pressure member 16 is working, taking the vertical pressure member 16 on the first gate plate 14 as an example, the spring 164 provides an elastic supporting force for the first gate plate 14 to vertically descend;

[0043] Furthermore, when the sleeve magnetic attraction component 23 is working, taking the sleeve magnetic attraction component 23 through which the first iron cable 24 passes as an example, the electromagnetic ring 232 generates magnetic attraction and fixes the first iron cable 24 after being energized. When the electromagnetic ring 232 is not energized, the electromagnetic ring 232 has no fixing effect on the first iron cable 24, and the first iron cable 24 can freely pass through the electromagnetic ring 232.

[0044] Furthermore, when the rotating component 21 is working, the driving motor 212 drives the shaft 211 to rotate, and the shaft 211 drives the rotating plate 22 of the side wall and the plurality of sleeve magnetic components 23 to rotate;

[0045] Furthermore, the first sealing component 18 facilitates to increase the sealing performance of the valve body 10 when the first gate plate 14 moves, and the second sealing component 19 facilitates to increase the sealing performance of the valve body 10 when the second gate plate 15 moves.

[0046] Please refer to the attached Figure 4 , 6 As shown in Figure 8, in another preferred embodiment of the present invention, both ends of the inner wall of the first flow channel 12 are provided with a tube diameter adjusting device 30, both ends of the first flow channel 12 are connected to the infusion tube 17, the tube diameter adjusting device 30 includes a cylindrical groove 31 embedded in the inner wall of the first flow channel 12, a rubber tube 32 provided in the cylindrical groove 31 and connected to the first flow channel 12, and a pneumatic component 33 provided at the bottom of the valve body 10 and used for supplying or exhausting air to the gap between the cylindrical groove 31 and the rubber tube 32, the pneumatic component 33 includes an air pressure sensor 331 provided on the inner wall of the cylindrical groove 31, a first delivery pipe 332 with one end passing through the bottom of the valve body 10 and connected to the cylindrical groove 31, and a second delivery pipe 333 whose side wall is connected to multiple first delivery pipes 332.

[0047] It should be noted that, in the present embodiment, when the liquid flows through the connecting flow channel constructed in the valve body 10, the pipe diameter adjusting device 30 can adjust the flow rate. The larger the inner diameter, the greater the flow rate, and vice versa. Taking reducing the inner diameter to reduce the flow rate as an example, the controller triggers the positive and negative pressure system connected to the second delivery pipe 333, and the positive and negative pressure system inputs pressurized gas into the second delivery pipe 333. The pressurized gas enters the cylindrical groove 31 through the second delivery pipe 333 and the first delivery pipe 332. The pressurized gas squeezes the rubber tube 32 to reduce the inner diameter of the rubber tube 32. The controller receives the air pressure information from the air pressure sensor 331 and closes the positive and negative pressure system connected to the second delivery pipe 333 when the air pressure information reaches the set value.

[0048] Please refer to the attached Figure 4-6As shown, in another preferred embodiment of the present invention, the end of the infusion tube 17 close to the valve body 10 is provided with a caliber adjustment device 40, and the other end is provided with a flow monitoring device 50, the caliber adjustment device 40 includes a positioning tube 41 arranged on the outer wall of the valve body 10 and sleeved on the outside of the infusion tube 17, a plurality of elastic clips 42 arranged in an annular array at one end of the positioning tube 41 away from the valve body 10, a translation driving component 43 arranged on the outer wall of the valve body 10, and a flow monitoring device 50 arranged on the translation driving component 43. The component 43 has an execution end and a pressure ring 44 mounted on the outer wall of the elastic clip 42, and the inner wall of the pressure ring 44 is an inclined surface. The translation driving component 43 includes a positioning frame 431, and a driving cylinder 432 which is arranged on the side of the positioning frame 431 away from the valve body 10 and the execution end passes through the positioning frame 431 and is connected to the outer wall of the valve body 10. The top of the positioning frame 431 is connected to the outer wall of the pressure ring 44. The flow monitoring device 50 includes a flow sensor 51 arranged on the outer wall of the infusion tube 17.

[0049] It should be noted that, in the present embodiment, the caliber adjustment device 40 is convenient for adjusting the caliber of the inlet and outlet of the valve body 10, so as to control the flow rate of the input and output of the valve body 10. When the caliber adjustment device 40 is working, the actuator end of the driving cylinder 432 drives the positioning frame 431 and the pressure ring 44 to move. As the pressure ring 44 moves, the inner wall of the pressure ring 44 simultaneously applies pressure to the multiple elastic clips 42, so that the multiple elastic clips 42 produce a closing movement, so as to squeeze the outer wall of the infusion tube 17, so as to reduce the inner diameter of the infusion tube 17, so as to reduce the flow rate;

[0050] Furthermore, the controller receives flow data from a plurality of flow sensors 51 to understand the flow information of the liquid inlet and outlet of the valve body 10 , and simultaneously triggers the pipe diameter adjustment device 30 and the caliber adjustment device 40 to adjust the flow.

[0051] The specific process of the present invention is as follows:

[0052] The controller model is "6ES7321-1BL00-0AA0", the air pressure sensor 331 model is "GPT200", and the flow sensor 51 model is "LWGY-FMT".

[0053] When the valve is in use, the vertical pressure-applying component 16 applies vertical downward pressure to the first gate plate 14 and the second gate plate 15, so as to seal the two ends of the first flow channel 12 and the second flow channel 13, so that the valve body 10 is in a closed state. At this time, the valve body 10 cannot enter the liquid. The corresponding first gate plate 14 and the second gate plate 15 are opened according to the passage requirements. When the passage is constructed, one inlet can correspond to one or more outlets, or multiple outlets can correspond to one or more inlets. When the valve is opened, the first gate plate 14 at the corresponding inlet and outlet moves up to open. If the inlet and outlet are separated by the second flow channel 13, the second gate plate 15 corresponding to the second flow channel 13 is opened. If the inlet and outlet are separated by the second flow channel 13, the second gate plate 15 corresponding to the second flow channel 13 is opened. If the second flow channel 13 is not separated, the second gate 15 will not be opened. When the gate is opened, the controller triggers the sleeve magnetic attraction component 23 corresponding to the first iron cable 24 and the second iron cable 25 to be pulled according to the setting of the passage construction. At this time, the sleeve magnetic attraction component 23 magnetically fixes the first iron cable 24 and the second iron cable 25. After the rotating component 21 works, the sleeve magnetic attraction component 23 drives the first iron cable 24 and the second iron cable 25 to move, so as to drive the first gate 14 and the second gate 15 to move upward. When the hole on the first gate 14 coincides with the first flow channel 12, it means that the first gate 14 is opened. When the hole on the second gate 15 coincides with the second flow channel 13, it means that the second gate 15 is opened.

[0054] When the vertical pressure member 16 is working, taking the vertical pressure member 16 on the first gate plate 14 as an example, the spring 164 provides an elastic supporting force for the first gate plate 14 to vertically descend;

[0055] When the sleeve magnetic attraction component 23 is working, taking the sleeve magnetic attraction component 23 through which the first iron cable 24 passes as an example, the electromagnetic ring 232 generates magnetic attraction to fix the first iron cable 24 after being energized. When the electromagnetic ring 232 is not energized, the electromagnetic ring 232 has no fixing effect on the first iron cable 24, and the first iron cable 24 can freely pass through the electromagnetic ring 232.

[0056] When the rotating component 21 is working, the driving motor 212 drives the shaft 211 to rotate, and the shaft 211 drives the rotating plate 22 of the side wall and the plurality of sleeve magnetic suction components 23 to rotate;

[0057] The first sealing component 18 is convenient for increasing the sealing performance of the valve body 10 when the first gate plate 14 moves, and the second sealing component 19 is convenient for increasing the sealing performance of the valve body 10 when the second gate plate 15 moves. Taking the first sealing component 18 as an example, the first rubber ring 181 can prevent the liquid from flowing out of the valve body 10 through the gap between the first gate plate 14 and the valve body 10 when the first gate plate 14 moves, and the first rubber ring 181 and the second rubber ring 182 can prevent the liquid from flowing into the valve body 10 through the gap between the first gate plate 14 and the valve body 10 after the first gate plate 14 is closed;

[0058] When the liquid flows through the connecting flow channel constructed in the valve body 10, the pipe diameter regulating device 30 can regulate the flow rate. The larger the inner diameter, the greater the flow rate, and vice versa. Taking reducing the inner diameter to reduce the flow rate as an example, the controller triggers the positive and negative pressure system connected to the second delivery pipe 333, and the positive and negative pressure system inputs pressurized gas into the second delivery pipe 333. The pressurized gas enters the cylindrical groove 31 through the second delivery pipe 333 and the first delivery pipe 332. The pressurized gas squeezes the rubber tube 32 to reduce the inner diameter of the rubber tube 32. The controller receives the air pressure information of the air pressure sensor 331 and closes the positive and negative pressure system connected to the second delivery pipe 333 when the air pressure information reaches the set value.

[0059] The caliber adjustment device 40 is convenient for adjusting the caliber of the inlet and outlet of the valve body 10, so as to control the flow of the input and output of the valve body 10. When the caliber adjustment device 40 is working, the actuator end of the driving cylinder 432 drives the positioning frame 431 and the pressure ring 44 to move. As the pressure ring 44 moves, the inner wall of the pressure ring 44 simultaneously applies pressure to the multiple elastic clips 42, so that the multiple elastic clips 42 produce a closing movement, so as to squeeze the outer wall of the infusion tube 17, so as to reduce the inner diameter of the infusion tube 17, so as to reduce the flow rate;

[0060] The controller receives flow data from a plurality of flow sensors 51 to obtain information on the flow of liquid in and out of the valve body 10 , and simultaneously triggers the pipe diameter adjustment device 30 and the aperture adjustment device 40 to adjust the flow.
