Therefore, when manufacturing the rotating slip ring, the requirements for the opening of the annular flow channel are usually high, and the production and manufacturing of the rotating slip ring components are somewhat difficult. In addition, the number of flow channels in various places inside the fluid distribution valve is large, the positions are complex and easy to connect incorrectly, the overall structure is complex, and assembly and maintenance are relatively inconvenient.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Embodiment 1

[0024] like Figure 1 , 2 As shown, the utility model discloses a fluid distribution valve, including a plane rotary switching valve 1, a fixed pipeline 2, an intermediate hose 3 and a transmission device 4. The plane rotary switching valve 1 includes a fixed valve disc 11 and a rotary valve disc 12 which is sealed and connected to the fixed valve disc 11 and can rotate around the central axis; the fixed valve disc 11 and the rotary valve disc 12 are evenly distributed with N pairs of fluid channels 13 which are arranged in correspondence and pass through the valve disc body, and each pair of fluid channels 13 includes a feed fluid channel 131 and a discharge fluid channel 132, wherein N≥2. In the case of adopting a vertical structure as a whole, the feed fluid channel 131 and the discharge fluid channel 132 in each pair of fluid channels 13 are preferably arranged vertically through, so as to continuously guide the fluid between the fixed pipeline 2 and the plane rotary switching valve 1.

[0025] M pairs of fixed pipes 2 are provided, and each pair of fixed pipes 2 includes a feed fixed pipe 21 and a discharge fixed pipe 22, wherein M≥2, and N≥M. The end of the flexible intermediate hose 3 is directly connected to the fixed pipe 2 and the fluid channel 13 of the rotary valve disc 12, thereby connecting the fixed pipe 2 and the fluid channel 13 on the rotary valve disc 12. That is, the feed fixed pipe 21 is connected to the feed fluid channel 131 on the rotary valve disc 12, and the discharge fixed pipe 22 is connected to the discharge fluid channel 132 on the rotary valve disc 12.

[0026] The fixed pipes 2 are relatively fixed to the fixed valve disc 11. In general, the number of fixed pipes 2 corresponds to the number and position of the fluid channels 13 on the rotating valve disc 12. The fixed pipes 2 are connected to the fluid channels 13 on the rotating valve disc 12 through the intermediate hose 3 in a connection manner that a pair of fixed pipes 2 are connected to a pair of fluid channels 13 through the intermediate hose 3.

[0027] However, according to the fluid processing requirements, the fixed pipe 2 can be connected to the fluid channel 13 on the rotary valve disc 12 through the intermediate hose 3. The connection method can also be a pair of fixed pipes 2 connected in series with multiple pairs of fluid channels 13 through the intermediate hose 3, so that when the reaction vessel 5 is used, the same fixed pipe 2 can be connected to multiple reaction vessels 5, and multiple reaction vessels 5 are connected in series, guiding the fluid to enter and exit the corresponding reaction vessel 5 for processing. Alternatively, the fixed pipe 2 can be connected to the fluid channel 13 on the rotary valve disc 12 through the intermediate hose 3. The connection method can also be a pair of fixed pipes 2 connected in parallel with multiple pairs of fluid channels 13 through the intermediate hose 3, so that multiple reaction vessels 5 are processed in parallel synchronously. Or further, the fixed pipe 2 can be connected to the fluid channel 13 on the rotary valve disc 12 through the intermediate hose 3. The connection method can also be a pair of fixed pipes 2 connected in series and parallel with multiple pairs of fluid channels 13 through the intermediate hose 3, and the efficiency of distributing and processing fluids is higher. After connection, the feed fixed pipe 21 is connected to the feed fluid channel 131, and the discharge fixed pipe 22 is connected to the discharge fluid channel 132.

[0028] The transmission device 4 is used to drive the rotating valve disc 12 to reciprocate. The transmission device 4 can be fixedly connected to the outside of the fixed valve disc 11, and drive the rotating valve disc 12 to reciprocate around the central axis within a certain angle range through belt transmission, gear transmission, etc., thereby driving the fluid channel 13 on the rotating valve disc 12 to rotate and shift, and then switch the corresponding fluid channel 13 on the fixed valve disc 11, so as to achieve the purpose of switching the flow channel to distribute the fluid. Correspondingly, the port positions of the fluid channel 13 on the fixed valve disc 11 and the fluid channel 13 on the rotating valve disc 12 need to be set relatively, and both are arranged along the same arc trajectory or circular trajectory centered on the central axis.

[0029] When the transmission device 4 drives the rotary valve disc 12 to rotate back and forth, the rotary valve disc 12 can rotate forward to a specific angle in the same direction once or multiple times within a certain angle range, and then rotate in the opposite direction to return to the initial position, thereby realizing the valve port switching of one rotation cycle. The maximum angle of the reciprocating rotation of the rotary valve disc 12 is set according to the actual conditions such as the distance between the fixed pipeline 2 and the plane rotary switching valve 1, the length of the intermediate hose 3, etc., and the angle of a single rotation is set according to the spacing angle between each pair of fluid channels 13. Preferably, the maximum angle value of the rotary valve disc 12 in the forward or reverse direction is between 150° and 170°. Reciprocating the rotary valve disc 12 within the set range for switching can ensure the continuous delivery of the fluid without twisting and damaging the intermediate hose 3.

[0030] Embodiment 2

[0031] like Figure 3-5As shown, the utility model also discloses a fluid reaction device, including the above-mentioned fluid distribution valve and a plurality of reaction containers 5, the reaction container is provided with a feed liquid inlet 51 and a liquid outlet, the feed fluid channel 131 on the fixed valve disc 11 is connected to the feed liquid inlet 51 on the corresponding reaction container 5 through a pipeline, and the discharge fluid channel 132 on the fixed valve disc 11 is connected to the feed liquid outlet 52 on the corresponding reaction container 5 through a pipeline.

[0032] Taking the case where a pair of fixed pipes 2 are connected to a pair of fluid channels 13 as an example, when inputting fluid, the fluid can be sequentially sent to the corresponding reaction container 5 through the feed fixed pipe 21, the intermediate hose 3, the feed fluid channel 131 on the rotary valve disc 12, and the feed fluid channel 131 on the fixed valve disc 11 for processing. Similarly, after the processing is completed, the fluid can be sequentially discharged through the discharge fluid channel 132 on the fixed valve disc 11, the discharge fluid channel 132 on the rotary valve disc 12, the intermediate hose 3, and the discharge fixed pipe 22, thereby completing the discharge. Afterwards, the rotary valve disc 12 can be rotated to switch the fluid channel 13, thereby switching the corresponding reaction container 5, and the fluid can be sequentially sent to the corresponding fluid for processing.

[0033] At the same time, by changing the connection method between the fixed pipeline 2 and the fluid channel 13 on the rotary valve disk 12, the fluid in each reaction container 5 can be processed in series, or multiple reaction containers 5 can be connected in parallel for batch processing, or both series processing and parallel processing can be used to improve processing efficiency.

[0034] In summary, the fluid distribution valve and fluid reaction equipment provided by the utility model have a simple structure and are relatively easy to manufacture, assemble and maintain, and can be applied to a variety of application scenarios that require continuous delivery and distribution of fluids.

[0035] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes in form and details of the present invention are within the scope of protection of the present invention without departing from the spirit and scope of the present invention as defined in the appended claims.
