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...

Abstract

The porous rotary-cut valve comprises a valve body fixing seat, a porous rotary-cut valve head is fixedly arranged at the top of the valve body fixing seat, and a rotating core is rotationally arranged in the valve body fixing seat; a plurality of hole sites are arranged on the multi-hole rotary-cut valve head; a rotary-cut valve plate is fixedly arranged on the rotating core and is in mirror surface contact with the bottom end surface of the porous rotary-cut valve head; the rotary-cut valve plate is provided with a plurality of channels enabling hole sites of the valve head of the porous rotary-cut valve to be communicated pairwise. The rotary-cut valve plate is driven to rotate by rotating the rotary core, so that a plurality of channels on the rotary-cut valve plate are in different states, the channels on the rotary-cut valve plate are communicated with hole sites on the valve head of the porous rotary-cut valve in pairs, and the structural design can realize the communication of two adjacent hole sites on the valve head and the communication of two non-adjacent hole sites of the valve head. And only two hole sites are communicated in each state, and the flow paths are mutually independent and do not influence each other, so that a complex flow path system can be simplified, and the experiment efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of valve body and flow injection, in particular to a multi-hole rotary valve that realizes communication between two and two. Background technique [0002] The rotary valve in the prior art includes a rotary valve with a common port, a rotary valve without a common port, and a rotary valve in which some ports are connected to each other; [0003] A rotary valve with a common port, that is, one common port corresponds to multiple gate ends, and the common port can be connected to any one of the gate ends. [0004] All channels of the rotary valve without a common port are connected to each other, that is, all channels are completely connected to each other; [0005] A rotary valve with some ports connected to each other can only connect some of its ports to each other. [0006] Among the above rotary valves, the valve with a common port cannot realize the communication between the gate ports; althou...
