Embodiment 1
[0036] like figure 1 As shown in the figure, the present invention provides a multi-hole rotary cut valve for realizing two-to-two communication, which includes a valve body fixing seat 1, the top of the valve body fixing seat 1 is fixedly provided with a porous rotary cutting valve head 2, and the valve body fixing seat 1 A rotating core 3 is arranged in the internal rotation;
[0037] The valve head 2 of the multi-hole rotary cut valve is provided with a plurality of hole positions 4, and the plurality of hole positions 4 are evenly distributed on the same circle with the center of the multi-hole rotary valve head 2 as the center, and each hole position 4 is matched with a channel. 5. Each channel 5 runs through the bottom end face of the valve head 2 of the porous rotary valve;
[0038] The rotary core 3 is fixedly provided with a rotary cutting valve sheet 6, and the upper end face of the rotary cutting valve sheet 6 is in mirror contact with the bottom end face of the mu...
Embodiment 2
[0040] like Figure 1~Figure 3 As shown, this embodiment is further limited on the basis of Embodiment 1. The multi-hole rotary cut valve that realizes the communication between two in the present invention also includes a driving member for driving the rotating core 3 to rotate around its own axis, and the driving member includes a step The input motor 8 is provided with a mechanical transmission member 9 on the output shaft of the stepping motor 8, and the mechanical transmission member 9 is fixedly connected with the rotating core 3 through the valve body fixing seat 1; the stepping motor 8 is provided with a control step motor 8 to rotate Angle controller 10. The rotation angle of the stepping motor is controlled by the controller 10, and the output shaft of the stepping motor 8 drives the rotating core 3 to rotate through the mechanical transmission member 9, thereby realizing that the plurality of channels 7 on the rotary cutting valve plate 6 are in different states.

Embodiment 3
[0045] like Figure 1~Figure 4 As shown, this embodiment is further limited on the basis of Embodiment 2. As a specific setting method of the valve head 2 of the multi-hole rotary cutting valve, the valve head 2 of the multi-hole rotary cutting valve is provided with 4 holes 4 and 4 holes. The hole positions 4 are evenly distributed on the same circle with the center of the valve head 2 of the multi-hole rotary cut valve as the center of the circle. For ease of understanding, four letters A, B, C, and D are set on the surface of the valve head 2 of the multi-hole rotary cut valve, which correspond to four hole positions 4 respectively. In this embodiment, the four hole positions 4 are referred to as A hole positions , B hole position, C hole position and D hole position.
[0046] The rotary valve plate 6 is provided with a first channel 13 and a second channel 14, the first channel 13 is a linear structure, the first channel 13 passes through the center of the rotary valve pl...
