[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 , 2 As shown, this utility model discloses a fluid distribution valve, including a planar rotary switching valve 2, a rotary flow channel connector 1, a connecting pipe 3, and a transmission device 5.

[0033] The planar rotary switching valve 2 includes a fixed valve disc 21 and a rotary valve disc 22 that can rotate around a central axis. Both the fixed valve disc 21 and the rotary valve disc 22 are disc-shaped and arranged opposite each other. The fixed valve disc 21 and the rotary valve disc 22 are sealed together. Both the fixed valve disc 21 and the rotary valve disc 22 are provided with N pairs of corresponding fluid channels 23 that pass through the valve disc body. Each pair of fluid channels 23 includes a feed fluid channel 231 and a discharge fluid channel 232. Wherein, N≥2. When the rotary valve disc 22 is driven to rotate, the fluid channels 23 on the rotary valve disc 22 can change position accordingly, thereby corresponding to and communicating with the fluid channels 23 at other positions on the fixed valve disc 21, realizing the switching of flow channels.

[0034] The rotary flow channel communication device 1 comprises a fixed flow channel disc 11 and a rotary flow channel disc 12 rotatable around a central axis, the fixed flow channel disc 11 and the rotary flow channel disc 12 are both disc-shaped, the fixed flow channel disc 11 and the rotary flow channel disc 12 are sealingly connected and arranged in an upper-lower manner. The fixed flow channel disc 11 is provided with M pairs of feeding ports 111 and discharging ports 112, and M pairs of annular flow channels 14 are formed between the fixed flow channel disc 11 and the rotary flow channel disc 12, the annular flow channels 14 correspond to the feeding ports 111 and the discharging ports 112 on the fixed flow channel disc 11 one by one and are in communication. The rotary flow channel disc 12 is provided with M pairs of intermediate flow channels 121 corresponding to the annular flow channels 14 and in communication, and the intermediate flow channels 121 are connected with the fluid passages 23 on the rotary valve disc 22 through the connecting pipes 3. Wherein, M≥2, and N≥M. When the rotary flow channel disc 12 is driven to rotate, each annular flow channel 14 can always communicate between the corresponding feeding port 111, discharging port 112 and the corresponding intermediate flow channel 121, ensuring the continuous delivery of the fluid.

[0035] Specifically, a plurality of annular grooves 113 are arranged on the outer side of the fixed flow channel disc 11 and / or the rotary flow channel disc 12, each annular groove 113 is coaxially arranged, and a certain spacing is left between adjacent annular grooves 113. When the annular grooves 113 are arranged on the side of the fixed flow channel disc 11 facing the rotary flow channel disc 12, the annular flow channels 14 are formed by the annular grooves 113 and the outer side of the rotary flow channel disc 12. Similarly, when the annular grooves 113 are arranged on the fixed flow channel disc 11 and the rotary flow channel disc 12 and the positions of the annular grooves 113 correspond to each other, the annular flow channels 14 are formed by the annular grooves 113. In this embodiment, the annular grooves 113 are uniformly arranged on the bottom end surface of the fixed flow channel disc 11.

[0036] The inner and outer sides of any annular flow channel 14 are provided with a sealing ring 13, which is fixedly arranged on the outer side of the fixed flow channel disc 11 and / or the rotary flow channel disc 12. The sealing ring 13 can ensure the sealing of the connection between the fixed flow channel disc 11 and the rotary flow channel disc 12, and ensure that each annular flow channel 14 is independent and does not interfere with each other, so that the annular flow channel 14 can better guide the fluid.

[0037] Since the rotary flow channel communication device 1 ensures that the annular flow channels 14 for continuous fluid guidance are formed by the disc-shaped fixed flow channel disc 11 and the rotary flow channel disc 12, each annular flow channel 14 can be coaxially arranged and arranged horizontally one by one, or even on the same horizontal plane, so that the overall height of the equipment can be greatly reduced, and it is suitable for installation in low-height places. The structures of the fixed flow channel disc 11 and the rotary flow channel disc 12 are relatively simple, so the manufacturing, installation and disassembly, and subsequent maintenance are relatively easy.

[0038] The plane rotary switching valve 2 is connected with the rotary flow channel adapter 1 through the connecting pipe 3. Generally, the connecting pipe 3 is a rigid pipe. The connecting mode of the intermediate flow channel 121 connecting the fluid passage 23 on the rotary valve disc 22 through the connecting pipe 3 can be that a pair of intermediate flow channels 121 connect a pair of fluid passages 23 through the connecting pipe 3, and then transport the fluid between the rotary flow channel adapter 1 and the plane rotary switching valve 2.

[0039] According to actual needs, the connecting mode of the intermediate flow channel 121 connecting the fluid passage 23 on the rotary valve disc 22 through the connecting pipe 3 can also be that a pair of intermediate flow channels 121 connect multiple pairs of fluid passages 23 in series through the connecting pipe 3. Or as shown in Figure 3 、 4 , the connecting mode of the intermediate flow channel 121 connecting the fluid passage 23 on the rotary valve disc 22 through the connecting pipe 3 can also be that a pair of intermediate flow channels 121 connect multiple pairs of fluid passages 23 in parallel through the connecting pipe 3, improving the fluid processing efficiency. Or further, the connecting mode of the intermediate flow channel 121 connecting the fluid passage 23 on the rotary valve disc 22 through the connecting pipe 3 can also be that a pair of intermediate flow channels 121 connect multiple pairs of fluid passages 23 in series and in parallel through the connecting pipe 3, and then flexibly distribute the fluid. At this time, the connecting pipe 3 used can be a hose or a hard pipe, which is less likely to be twisted and damaged when the rotary flow channel disc 12 and the rotary valve disc 22 rotate.

[0040] The transmission device 5 is used to drive the rotary flow channel disc 12 and the rotary valve disc 22 to rotate. The transmission device 5 can be driven in various ways. In this embodiment, the transmission device 5 includes a first transmission device 51 and a second transmission device 52. The first transmission device 51 is fixedly connected to the fixed flow channel disc 11 and drivingly connected to the rotary flow channel disc 12. The second transmission device 52 is fixedly connected to the fixed valve disc 21 and drivingly connected to the rotary valve disc 22. In this case, the rotary flow channel disc 12 and the rotary valve disc 22 are provided with a position sensor 6 opposite each other. The relative position between the rotary flow channel disc 12 and the rotary valve disc 22 can be sensed by the position sensor 6. When the first transmission device 51 and the second transmission device 52 drive the rotary flow channel disc 12 and the rotary valve disc 22 to rotate, the synchronous rotation or following movement of the rotary flow channel disc 12 and the rotary valve disc 22 can be better controlled.

[0041] Embodiment Two

[0042] As shown in Figure 5 , the difference from the first embodiment is that the rotary flow channel disc 12 and the rotary valve disc 22 are connected with a rigid rotating shaft 4 at the center axis. The transmission device 5 is fixedly arranged at the top of the fixed flow channel disc 11 or the bottom of the fixed valve disc 21 and connected with the rigid rotating shaft 4. The rigid rotating shaft 4 can simultaneously drive the rotary flow channel disc 12 and the rotary valve disc 22 to rotate.

[0043] Example 3

[0044] like Figure 6 As shown, the difference between this embodiment and embodiment 2 is that the transmission device 5 is fixedly installed on the side of the fixed valve disc 21, which is more suitable for production sites with limited installation height. The transmission device 5 is connected to the side of the rotating valve disc 22 through conventional transmission connection methods such as chain connection and gear connection, thereby driving the rotating valve disc 22 to rotate. At the same time, under the drive of the rigid rotating shaft 4, the rotating flow channel disc 12 rotates accordingly.

[0045] Example 4

[0046] like Figures 7-9 As shown, based on any of the above embodiments, this utility model also discloses a fluid reaction device, including a plurality of reaction containers 7 and the above-mentioned fluid distribution valve. The reaction containers 7 are provided with a liquid inlet 71 and a liquid outlet 72. The feed fluid channel 231 on the fixed valve disc 21 is connected to the liquid inlet 71 on the corresponding reaction container 7 through a pipe, and the discharge fluid channel 232 on the fixed valve disc 21 is connected to the liquid outlet 72 on the corresponding reaction container 7 through a pipe.

[0047] Taking the case where a pair of intermediate flow channels 121 connect to a pair of fluid channels 23 as an example, when the equipment is in use, the liquid to be processed can be sequentially introduced into the corresponding reaction vessel 7 through the inlet 111, the annular flow channel 14, the intermediate flow channel 121, the connecting pipe 3, the inlet fluid channel 231 on the rotary valve disc 22, and the inlet fluid channel 231 on the fixed valve disc 21 for processing. After processing, it is sequentially output through the liquid outlet 72 on the reaction vessel 7, the outlet fluid channel 232 on the fixed valve disc 21, the outlet fluid channel 232 on the rotary valve disc 22, the connecting pipe 3, the intermediate flow channel 121, the annular flow channel 14, and the outlet 112, realizing cyclic feeding and discharging. Subsequently, the rotary valve disc 22 is driven by the transmission device 5 to switch the fluid channels 23 on the rotary valve disc 22, so that the liquid can be sequentially distributed to different reaction vessels 7 for processing.

[0048] In addition, by changing the connection method of the connecting pipe 3, the intermediate flow channel 121 and the fluid channel 23 on the rotary valve disc 22 can be connected in series to realize the series processing of multiple reaction vessels 7, or the intermediate flow channel 121 and the fluid channel 23 on the rotary valve disc 22 can be connected in parallel to realize the parallel processing between reaction vessels 7, or both series and parallel connections can be used at the same time to improve the processing efficiency.

[0049] In summary, the fluid distribution valve and fluid reaction equipment provided by this utility model have a simple structure, are easy to manufacture and assemble, and can continuously and sequentially distribute fluids during use. They are suitable for various production sites, especially production sites with low ceilings.

[0050] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all of them are within the protection scope of the utility model.
