Description

TECHNICAL FIELD

[0001] The utility model relates to liquid flow technology field, concretely relates to a multiway valve device. BACKGROUND

[0002] In the application of continuous ion exchange system, there are two implementation modes of moving bed and fixed bed simulated moving bed. The moving bed adopts a rotary valve distribution system, which needs to rotate the resin column as a whole by a rotary disc, which has the disadvantages of limited volume, tilting of the valve disc due to different fluid densities, and easy damage of the rolling support wheel. The fixed bed simulated moving bed can use a valve array distribution system and a multiway valve distribution system. The valve array distribution system has the disadvantages of large number of valves, high failure rate, and process customization. The multiway valve distribution system has the disadvantages of process customization and excessive pressure difference in the valve, which easily leads to leakage.

[0003] The existing multiway valve device, such as the one disclosed in CN1452513A, realizes the operation of the multiway valve by flowing the medium into the liquid inlet at the top of the valve and outputting the medium from the side wall of the rotary valve. The internal rotary valve of the multiway valve device realizes the distribution of the liquid. However, the internal rotary valve needs to be customized according to the process, which is limited by the size of the valve, resulting in limited function of the rotary valve. In addition, the internal rotary valve sealing involves multi-dimensional sealing, which is prone to internal leakage of the valve due to pressure difference.

[0004] In addition, for example, the multiway valve device disclosed in CN215980953U, by making the liquid inlet and outlet fixed parts, only need to directly connect each passage in the output process, so as to change the original device side rotary cooperation to axial rotary cooperation, change the liquid flow direction, greatly reduce the possibility of liquid leakage. However, this structure only reduces the possibility of liquid leakage, and the multi-layer superposition structure only uses two end fastening seals, and the device has low pressure resistance.

[0059] The first fixing member 1 has a first flow channel (such as...) Figure 2 As shown, for example, in the illustrated embodiment, the first flow channel includes a first inlet 11a for material A, a first inlet 12b for material B, a first inlet 13c for material C, and a first inlet 14d for material D; the first rotating liquid distributor 2 rotates relative to the first fixed member 1 under the drive of the first driver 71; the first rotating liquid distributor 2 has a first annular flow channel communicating with the first fixed member 1 (e.g., Figure 3a As shown, for example, the first annular flow channel includes a first annular flow channel 20a for material A, a first annular flow channel 20b for material B, a first annular flow channel 20c for material C, and a first annular flow channel 20d for material D; the first rotating liquid distributor 2 has a first L-shaped flow channel (e.g., ...) that communicates with the second rotating liquid distributor 5.

Figure 3b As shown, for example, in the illustrated embodiment, the second L-shaped flow channel includes a second annular flow channel 22a for material A, a second annular flow channel 22b for material B, a second annular flow channel 22c for material C, and a second annular flow channel 22d for material D; the first rotating liquid distributor 2 has a second L-shaped flow channel communicating with the second rotating liquid distributor 5 (e.g., Figure 3b and Figure 3cAs shown, for example, in the illustrated embodiment, the second annular flow channel includes a second L-shaped flow channel 23a for material A, a second L-shaped flow channel 23b for material B, a second L-shaped flow channel 23c for material C, and a second L-shaped flow channel 23d for material D; the second fixing member 3 is fixedly disposed relative to the first fixing member 1; the third fixing member 4 is fixedly disposed relative to the fourth liquid distribution fixing member 6; the second rotating liquid distribution member 4 rotates relative to the first fixing member 1 under the drive of the second driver 72; the second rotating liquid distribution member 4 has the same rotation angle and rotation direction as the first rotating liquid distribution member 2; the second rotating liquid distribution member 4 has the same rotation angle and rotation direction as the first rotating liquid distribution member 2. The system includes a third L-shaped flow channel 50; a second rotating liquid distributor 4 having a fourth L-shaped flow channel 51 connected to the first rotating liquid distributor 2; the second rotating liquid distributor 4 having a third L-shaped flow channel 50 and a fourth L-shaped flow channel 51 fixedly connected to the fourth liquid distribution fixing member 6; and at least one storage tank connected between a fifth L-shaped flow channel 60 (e.g., in the illustrated embodiment, the fifth L-shaped flow channel includes fifth L-shaped flow channels 6001 to 6010) and a sixth L-shaped flow channel 61 (e.g., in the illustrated embodiment, the sixth L-shaped flow channel includes sixth L-shaped flow channels 6101 to 6110).

[0060] The first rotating liquid distributor 2 and the second rotating liquid distributor 4 rotate in the same direction, with a rotation angle of α per cycle, where α = 360° / n, and n is the number of storage tanks connected to the liquid distribution valve. In this embodiment, n is 10, therefore, α = 36° in this embodiment.

[0061] In this embodiment, the storage tank also includes a first storage tank 81 and a second storage tank 82, and the fourth liquid distribution fixture also includes a fifth L-shaped flow channel 60 and a sixth L-shaped flow channel 61. In the initial position, the two ends of the first storage tank 81 are connected to the fifth L-shaped flow channel 6001 and the sixth L-shaped flow channel 6101, and the two ends of the second storage tank 82 are connected to the fifth L-shaped flow channel 6002 and the sixth L-shaped flow channel 6102.

[0062] When the cycle rotates, for example, when it rotates 36° clockwise, the two ends of the second storage tank 82 are connected to the fifth L-shaped flow channel 6002 and the sixth L-shaped flow channel 6102 respectively. The fifth L-shaped flow channel 6002 is connected to the third L-shaped flow channel 5001, and the sixth L-shaped flow channel 6102 is connected to the fourth L-shaped flow channel 5101.

[0063] For ease of description, the initial position is used as an example below. The first flow channel (for example, in the illustrated embodiment, the first flow channel includes a first inlet 11a for material A, a first inlet 11b for material B, a first inlet 11c for material C, and a first inlet 11d for material D) has a first inlet and a first outlet; the first annular flow channel 20 has a second inlet and a second outlet, with the second inlet communicating with the first outlet; the first L-shaped flow channel 21 has a third inlet and a third outlet, with the third inlet communicating with the second outlet; the second annular flow channel 22 has a fourth inlet and a fourth outlet; the second L-shaped flow channel 23 has a fifth inlet and a fifth outlet, with the fifth outlet communicating with the fourth inlet; the second flow channel (for example, in the illustrated embodiment, the second flow channel includes material A) has a first inlet and a first outlet. The first outlet 31a; the first outlets 31b (material B), 31c (material C), and 31d (material D) have a sixth inlet and a sixth outlet, the sixth inlet being connected to the fourth outlet; the third L-shaped flow channel 50 has a seventh inlet and a seventh outlet, the seventh inlet being connected to the third, fifth, and eighth outlets; the fourth L-shaped flow channel 51 has an eighth inlet and an eighth outlet, the eighth outlet being connected to the third, fifth, and seventh inlets; the fifth L-shaped flow channel 60 has a ninth inlet and a ninth outlet, the ninth inlet being connected to the seventh outlet, and the ninth outlet being connected to the storage tank; the sixth L-shaped flow channel 61 has a tenth inlet and a tenth outlet, the tenth inlet being connected to the storage tank, and the tenth outlet being connected to the eighth inlet.

[0064] In this embodiment, the third outlet and the fifth inlet are located on the side wall of the first rotating liquid distributor 2, the seventh inlet and the eighth outlet are located on the side wall of the second rotating liquid distributor 5, and the ninth outlet and the tenth inlet are located on the side wall of the fourth liquid distribution fixing member 6. Therefore, the communication with the rotating liquid distributor and the storage tank is led out from the side. Since the first rotating liquid distributor 2 is fixed relative to the second rotating liquid distributor 5, there is no liquid leakage problem between the first rotating liquid distributor 2 and the second rotating liquid distributor 5.

[0065] The multi-way valve device in this embodiment is provided with several annular seals, which are installed on the end face of the first fixing member 1 facing the first rotating liquid distributor 2 and / or the end face of the second fixing member 3 facing the first rotating liquid distributor 2 and / or the end face of the second rotating liquid distributor 5 facing the fourth liquid distribution fixing member 6. Simultaneously, two adjacent annular seals form a flow guiding channel to guide the flow of media between the first fixing member 1 and the first rotating liquid distributor 2, the flow of media between the sealing structure of the second fixing member 3 and the first rotating liquid distributor 2, and the flow of media between the sealing structure of the second rotating liquid distributor 5 and the fourth liquid distribution fixing member 6. The aforementioned annular seals achieve the guiding of liquid flow.

[0066] In this embodiment, the first rotating liquid distributor 2 and the second rotating liquid distributor 5 rotate coaxially, in the same direction, and at the same angle.

[0067] In this embodiment, the first rotating liquid distributor 2 and the second rotating liquid distributor 5 can be fixed to each other; the second fixing member 3 and the fourth liquid distribution fixing member 6 can be fixed to each other.

[0068] The multi-way valve provided in this embodiment also includes a fastening assembly, which includes: connector 1Y, connectors 4W, 4X, 4Y, 4Z, a first locking member, and a second locking member. The first locking member 1Z is disposed at the end of the first fixing member 1 away from the first rotating structure 2. The connector 1 passes through the first fixing member 1, the first rotating liquid distribution member 2, and the second fixing member 3. The first locking member is sleeved on the connector 1Y and abuts against the first fixing member 1 or the second fixing member 3 to limit the distance between the first fixing member 1 or the second fixing member 3.

[0069] Preferably, the first rotating liquid distribution component 2 rotates synchronously with the connecting component 1Y.

[0070] The second locking member is disposed at the end of the third fixing member 4 away from the fourth liquid distribution fixing member 6; the connecting members 4W, 4X, 4Y, and 4Z are inserted through the third fixing member 4, the second rotating liquid distribution member 5, and the fourth liquid distribution fixing member 6; the second locking member is sleeved on the connecting members 4W, 4X, 4Y, and 4Z and abuts against the third fixing member 4 or the fourth liquid distribution fixing member 6 to limit the distance between the third fixing member 4 or the fourth liquid distribution fixing member 6.

[0071] In this invention, only the connection mode of the second rotating liquid distribution structure channel and the connection mode between the side of the first rotating liquid distribution structure and the second rotating liquid distribution structure need to be changed during the output process, thereby changing the flow direction and flow mode of the liquid and fully developing the liquid flow mode change.

[0072] Furthermore, the multi-way valve device provided by this utility model uses fixed components at both the inlet and outlet during liquid transportation. Therefore, during output, the liquid only needs to be directly connected to the delivery port. The combination of the fixed components and the rotating structure unfolds the rotary valve and side valve body of the original device. By changing the channel connection method of the second rotating liquid distribution structure, different functional requirements are met, reducing the production and R&D costs of the original device and significantly improving the system's versatility and universality. The original device's rotary valve and side valve body surface seal is transformed into a pipeline seal, greatly reducing the possibility of liquid leakage and further avoiding side leakage problems, thus ensuring the system's pressure resistance and operational reliability.

[0073] Specifically in this embodiment, such as Figure 2As shown, the first fixing member 1 is provided with four flow channels (in this specific embodiment, they are inlets, i.e., the first inlet referred to below), namely, material A first inlet 11a, material B first inlet 11b, material C first inlet 11c, and material D first inlet 11d.

The number of material inlets in the first fixed component matches the number of material groups in the first rotating liquid distributor. By controlling the number of material groups and the flow rate in the first fixed component, intermittent material distribution or different flow rate distribution can be achieved. Figure 11a and Figure 11b As shown.

[0117] Sixth Embodiment

[0118] This embodiment provides a multi-way valve device, which differs from the multi-way valve devices provided in any of the first to fifth embodiments in that:

[0119] The first rotating liquid distributor is separated from the first annular flow channel and the second annular fluid flow channel to form two rotating distributors.
