Description

Technical Field

[0001] The invention relates to the technical field of liquid circulation, and in particular to a multi-way valve device. Background Art

[0002] In the application of continuous ion exchange system, there are two implementation modes: moving bed and fixed bed simulating moving bed. The moving bed adopts a turntable valve distribution system, which requires the turntable to drive the resin column to rotate and move as a whole. It has the disadvantages of limited volume, valve disc tilting due to different fluid density, and easy damage to the rolling support wheel. Fixed bed simulating moving bed can adopt valve array distribution system and multi-way valve distribution system. The valve array distribution system has the disadvantages of large valve usage, high failure rate and process customization; the multi-way valve distribution system has the disadvantages of process customization and excessive pressure difference in the valve and easy leakage.

[0003] In the existing multi-way valve device, such as the multi-way valve device disclosed in CN1452513A, the operation of the multi-way valve is realized 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, and the internal rotary valve of the multi-way valve device realizes the diversion of the liquid. However, the internal rotary valve needs to be customized according to the process requirements, and the function of the rotary valve is limited due to the valve size. In addition, the internal rotary valve seal involves multi-dimensional sealing, which is prone to pressure difference leading to internal leakage of the valve.

[0004] In addition, for example, in the multi-way valve device disclosed in CN215980953U, during the liquid delivery process, both the liquid inlet and the liquid outlet are fixedly arranged fixing parts, and during the output process, only the various passages need to be directly connected to each other, thereby changing the lateral rotation fit of the original device to an axial rotation fit, changing the liquid flow direction, and greatly reducing the possibility of liquid leakage. However, this structure only reduces the possibility of liquid leakage, and the multi-layer superposition structure only uses two ends of the fastening seal, and the pressure resistance of the device is low.

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

Therefore, the communication with the rotating liquid distribution member and the storage tank body is led out from the side, and since the first rotating liquid distribution member 2 is fixed relative to the second rotating liquid distribution member 5, there is no problem of liquid leakage in the first rotating liquid distribution member 2 and the second rotating liquid distribution member 5.

[0065] The multi-way valve device in this embodiment is provided with a plurality of annular seals, which are installed on the end surface of the first fixed member 1 facing the first rotating liquid distribution member 2 and / or the end surface of the second fixed member 3 facing the first rotating liquid distribution member 2 and / or the end surface of the second rotating liquid distribution member 5 facing the fourth liquid distribution fixed member 6. At the same time, two adjacent annular seals form a diversion channel to guide the flow of the medium between the first fixed member 1 and the first rotating liquid distribution member 2, and the flow of the medium between the second fixed member 3 and the sealing structure of the first rotating liquid distribution member 2, and the flow of the medium between the second rotating liquid distribution member 5 and the sealing structure of the fourth liquid distribution fixed member 6. The above-mentioned annular seals are arranged to achieve the diversion of the liquid.

By changing the channel connection mode of the second rotating liquid distribution structure, different functional requirements are achieved, the production and development cost of the original device is reduced, and the extensiveness and versatility of the system are greatly improved; the rotary valve and the side valve body surface seal of the original device are unfolded into a pipeline seal, which greatly reduces the possibility of liquid leakage, further avoids the problem of side leakage, and makes the pressure resistance and operation reliability of the system more guaranteed.

By controlling the number of material groups and flow rate of the first fixed member, intermittent distribution of materials or distribution of different flow rates can be achieved, such as Fig.11a and Fig.11b shown.

[0117] Sixth embodiment

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

[0119] The first rotating liquid distribution member is separated from the middle of the first annular flow channel and the second annular fluid flow channel to form two rotating distribution members, and the sealing form of the first rotating liquid distribution member is changed to two-stage independent compression seal, thereby improving the pressure resistance of the equipment, such as Fig.12 shown.
