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] At present, the most common devices used for continuous ion exchange and adsorption in industry are the "carousel" turntable system, valve array system and multi-way valve device. The turntable system requires the turntable to drive the resin column filled with resin to rotate as a whole. It cannot realize the production of large-scale systems and the core components of the turntable have the disadvantages of high manufacturing cost and difficult maintenance. Therefore, it cannot be widely used in various application fields. Although the valve array system can simulate the movement of resin by switching the valve multiple times without moving the resin column to achieve continuous operation, a large number of valves are required for systems with complex processes, and the control accuracy and safety of the system are very high. The multi-way valve device drives the rotating disk in the fixed shell through the motor, connects the feed pipe and the discharge pipe through the pipeline inside the rotating valve core, and realizes a completely continuous process without the movement of the resin and the resin column. The multi-way valve device avoids the complexity and bulkiness of the turntable system and the many hidden dangers caused by the high-frequency switching of the valve in the valve array system, and has been widely recognized and applied in the market.

[0003] In an existing multi-way valve device, such as the multi-way valve device disclosed in CN1452513A, the operation of the multi-way valve is achieved by flowing a medium into a liquid inlet at the top of the valve and outputting the medium from a side wall of the rotary valve. The internal rotary valve of the multi-way valve device realizes the diversion of the liquid.

[0147]

[0148] In the above embodiment, the storage tank is a hollow container, and the filler in the storage tank can be various fillers that need to be regenerated, such as one or more of silica gel, bonded silica gel, polymer, adsorbent, catalyst, filter medium, etc.

[0149] Tables 1 to 4 above show that when the multi-way valve device is in the starting position, four materials are circulated in sequence through four circulation loops, taking the first storage tank 61 and the second storage tank 62 as an example, for example, at this time, material A circulates in the first storage tank 61 and the second storage tank 62, material B circulates in the third storage tank 63 and the fourth storage tank 64, material C circulates in the fifth storage tank 65 and the sixth storage tank 66, and material D circulates in the seventh storage tank and the eighth storage tank 68.

[0150] When the driver 9 drives the first rotating structure 2 and the second rotating structure 4 to rotate, the materials flowing out of the first rotating structure 2 through the first branch 231 and the second branch 241 enter the liquid distribution structure 3 shown in Table 2 respectively, and flow into the fourth storage tank 64, the sixth storage tank 66, the eighth storage tank 68 and the second storage tank 62 through the second passage 34 in the liquid distribution structure 3. Correspondingly, the second rotating structure 4 corresponding to the third outlet side of the third passage 32 of the second rotating structure 4 is also changing, so that at this time, a group of integral passages only passes through the second storage tank 62, the fourth storage tank 64, the sixth storage tank 66 or the eighth storage tank 68 alone. It does not establish a connection with the first storage tank 61, the third storage tank 63, the fifth storage tank 65 and the seventh storage tank. Thereby realizing short-distance single material transportation and storage.

[0151] Therefore, the user can select the rotation angle of the rotary valve and the time for the rotary valve to stay at the corresponding angle according to different needs.

[0152] Example 2

[0153] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in Example 1 in that the driver of the multi-way valve device rotates 90 degrees each time, that is, each group of circuits can realize material flow through two storage tanks during rotation.

[0154] Example 3

[0155] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in Embodiment 1 or Embodiment 2 in that:

[0156] The number of storage tanks is reduced. For example, only two or three storage tanks are provided on the basis of two storage tanks flowing through each group of loops. Correspondingly, the first rotating structure 2 and the second rotating structure 4 rotate, and the rotation angle per cycle is α, where α=360° / n, where n is the number of storage tanks connected to the liquid dispensing valve. For example, when n is 4, therefore, in this embodiment, α=90°.

[0157] The number of storage tanks is increased. For example, on the basis of two storage tanks flowing through each group of loops, only five, six or more groups are set. Correspondingly, the first rotating structure 2 and the second rotating structure 4 rotate, and the rotation angle per cycle is α, where α=360° / n, where n is the number of storage tanks connected to the liquid distribution valve. For example, when n is 10, therefore, in this embodiment, α=36°.

[0158] Example 4

[0159] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in any one of Embodiments 1 to 3 in that:

[0160] Only one set of storage tanks is provided, and the first rotating structure 2 and the second rotating structure 4 rotate, and the rotation angle per cycle is α, where α=360° / n, where n is the number of storage tanks connected to the liquid distribution valve. For example, when n is 2, therefore, in this embodiment, α=180°. By distributing the fluid in the pipeline, the long pipeline and the short pipeline can be switched to each other.

[0161] Example 5

[0162] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in any one of Embodiments 1 to 4 in that:

[0163] There is only one storage tank for each group of circuits, for example, each group of circuits only flows through the first passage, the second passage, the third passage and the fourth passage. Similarly, the lateral leakage of the medium can be reduced by a vertical sealing method.

[0164] Example 6

[0165] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in any one of Embodiments 1 to 5 in that:

[0166] In the multi-way valve device of this embodiment, the upper and lower rotating structures can also be driven separately by two drivers. For example, the first driver drives the first rotating structure, and the second driver drives the second rotating structure. At this time, on-demand adjustment of different passages can be achieved.

[0167] Example 7

[0168] This embodiment provides a multi-way valve device, which is different from the multi-way valve device provided in any one of Embodiments 1 to 6 in that a storage tank may not be provided, and fluid distribution can be achieved as long as the flow pipeline is arbitrarily long.

[0169] Of course, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
