Description

Technical Field

[0001] This invention relates to the field of fluid control technology, and more specifically, to a control valve. Background Technology

[0002] Currently, in the field of fluid control technology, for a device to be controlled with multiple flow paths, multiple control valves are usually used to control multiple flow paths. Each control valve controls its corresponding flow path to be in a flowing state or a disconnected state.

[0003] However, the above setup not only increases the difficulty of controlling the control valve in the fluid system, but also increases the overall cost of the fluid system. Summary of the Invention

[0004] The main objective of this invention is to provide a control valve to solve the problem of complex control of multiple flow paths in existing control valves.

[0005] To achieve the above objectives, the present invention provides a control valve, comprising: a valve seat having a first valve chamber, a second valve chamber, a connecting port, a plurality of first valve ports and a plurality of second valve ports, wherein the first valve chamber is connected to the plurality of first valve ports, the second valve chamber is connected to the plurality of second valve ports, and the first valve chamber is connected to the second valve chamber through the connecting port; a first valve core movably disposed within the first valve chamber, the first valve core including a plurality of channels, at least one channel having two ends connected to two first valve ports respectively, and at least one first valve port being connected to the connecting port through the channel; and a second valve core movably disposed within the second valve chamber, the second valve core including a connecting portion for controlling the number of second valve ports connected to the connecting port.

[0006] According to the technical solution of this invention, the valve seat has a first valve chamber and a second valve chamber, which are connected by a connecting port. The control valve includes a first valve core and a second valve core. The first valve core is movably disposed within the first valve chamber to control the on / off connection between multiple first valve ports and between the first and second valve ports. The second valve core is movably disposed within the second valve chamber to control the number of connections between the second valve ports and the connecting port, thereby controlling multiple flow paths. Simultaneously, the connecting portion can also be used to regulate the flow rate entering each second valve port.

[0007] In this way, compared with the prior art which requires the use of multiple control valves to control multiple flow paths, the control valve in this application can control multiple flow paths simultaneously, thereby reducing the number of control valves used. This solves the problem that the control valves in the prior art are relatively complex to control multiple flow paths, reduces the control difficulty of the fluid system and reduces the manufacturing cost of the system.

[0008] Furthermore, the control valve also includes: a first driving device, which is driven to connect to the first valve core to drive the first valve core to rotate around its central axis, with a plurality of first valve ports spaced apart around the central axis of the first valve core; and / or, a second driving device, which is driven to connect to the second valve core to drive the second valve core to rotate around its central axis, with a plurality of second valve ports spaced apart around the central axis of the second valve core. The first driving device is driven to connect to the first valve core to drive the first valve core to rotate, thereby controlling the interconnection between the plurality of first valve ports and between the first valve ports and the second valve ports, so as to realize intelligent control of the control valve.

[0009] Furthermore, the central axis of the first valve port is parallel to the central axis of the second valve port. This arrangement allows the first and second valve cores to be spaced apart along the length or width of the control valve, thereby reducing the overall height and thickness of the control valve.

[0010] Furthermore, the valve seat includes: a valve seat body having multiple first flow holes and multiple second flow holes; a surrounding plate disposed on the valve seat body and located inside the multiple first flow holes and multiple second flow holes; both first valve ports and second valve ports are disposed on the surrounding plate; the multiple first flow holes are arranged in a one-to-one correspondence with the multiple first valve ports, and the multiple second flow holes are arranged in a one-to-one correspondence with the multiple second valve ports. The fact that both the first valve ports and second valve ports are disposed on the surrounding plate, and both the first flow holes and second flow holes are disposed on the valve seat body, facilitates communication between the multiple first valve ports through channels and between the first valve ports and the second valve ports through connecting ports, improving the control reliability of the control valve; on the other hand, it simplifies the structure of the valve seat, making it easier to manufacture and implement, and reducing the manufacturing cost of the valve seat.

[0011] Furthermore, the enclosure panel includes: a first enclosure panel segment, which is an arc-shaped panel segment, with a first valve port disposed on the side wall of the arc-shaped panel segment; a first transition panel segment and a second transition panel segment disposed opposite to each other, with the two sides of the arc-shaped panel segment respectively connected to the first transition panel segment and the second transition panel segment, forming a communication opening between the first transition panel segment and the second transition panel segment; and a second enclosure panel segment, which surrounds and forms a second valve cavity. The above configuration simplifies the structure of the enclosure panel, makes it easier to process and implement, and reduces the processing cost of the enclosure panel.

[0012] Furthermore, the first flow orifice is a fan-shaped orifice. This design increases the area of ​​the first flow orifice, improving the flow efficiency of the control valve; it also simplifies the structure of the first flow orifice, making it easier to manufacture and implement, thus reducing the manufacturing cost of the control valve.

[0013] Furthermore, the control valve also includes: a first sealing structure disposed between the first enclosure plate segment and the first valve core. The first sealing structure has multiple first through holes, each corresponding to a multiple first valve port. The first sealing structure is used to seal between the first enclosure plate segment and the first valve core to prevent fluid leakage to the outside of the first valve ports. Optionally, the first sealing structure is arc-shaped and also has an opening, which is positioned opposite to the connecting port.

[0014] Furthermore, the control valve also includes a second sealing structure disposed between the second enclosure plate segment and the second valve core; wherein the second sealing structure has a second through hole, and the connecting portion communicates with the second valve port through the second through hole. The second sealing structure is used to seal between the second enclosure plate segment and the second valve core to prevent fluid leakage to the outside of the second valve port. Optionally, the second sealing structure is annular.

[0015] Furthermore, the multiple channels include a first channel, and the first valve core further includes: a first plate; a second plate, disposed opposite to the first plate; and a third plate, disposed between the first and second plates and connected to both the first and second plates. The third plate, a portion of the first plate, and a portion of the second plate surround to form the first channel. An installation space is formed between the first and second plates, and the third plate is disposed within the installation space, so that the third plate, a portion of the first plate, and a portion of the second plate surround to form the first channel. The two ends of the first channel can be connected to two first valve ports respectively, or to a first valve port and a connecting port respectively.

[0016] Furthermore, the first and second plates are circular plates, and the third plate includes: a fourth plate segment extending radially along the circular plate; a fifth plate segment; and a sixth plate segment extending radially along the circular plate and forming a first angle A with the fourth plate segment; the two ends of the fifth plate segment are connected to the fourth and sixth plate segments respectively. This arrangement ensures that the third plate can form the first channel, and also simplifies the structure of the third plate, making it easier to process and implement, thus reducing the processing cost of the third plate.

[0017] Furthermore, the multiple channels also include a second channel, and the first valve core further includes a fourth plate, disposed between and connected to both the first and second plates, with the fourth plate spaced apart from the fifth plate segment; wherein the fourth plate, a portion of the first plate, a portion of the second plate, and the third plate surround each other to form a second channel. The fourth plate is disposed within the installation space so that the fourth plate, a portion of the first plate, a portion of the second plate, and the third plate surround each other to form the second channel. The two ends of the second channel can be connected to two first valve ports respectively, or to a first valve port and a connecting port respectively.

[0018] Furthermore, the fourth plate and the fifth plate segment are arranged parallel to each other; and / or, the fourth plate passes through the central axis of the second plate. This arrangement allows for greater flexibility in the placement of the fourth plate to meet different usage requirements and operating conditions.

[0019] Furthermore, the multiple channels also include a third channel, and the first valve core further includes: a fifth plate, disposed between and connected to both the first and second plates, one end of which is connected to the fourth plate at a second included angle B; and a sixth plate, disposed between and connected to both the first and second plates, extending radially along the circular plate and connected to the other end of the fifth plate, at a third included angle C with the fourth plate; wherein a portion of the fourth plate, the fifth plate, at least a portion of the sixth plate, a portion of the first plate, and a portion of the second plate surround each other to form the third channel. Both the fifth and sixth plates are disposed within the installation space, so that a portion of the fourth plate, the fifth plate, at least a portion of the sixth plate, a portion of the first plate, and a portion of the second plate surround each other to form the third channel. The two ends of the third channel can be connected to two first valve ports respectively, or to a first valve port and a connecting port respectively.

[0020] Furthermore, the multiple channels also include a fourth channel, and the first valve core further includes a seventh plate, disposed between and connected to both the first and second plates. The two ends of the seventh plate are connected to the fourth and sixth plates respectively, and the seventh plate and the fourth plate are arranged at a fourth included angle D. The fourth channel is formed by the arrangement of a portion of the fourth plate, the seventh plate, at least a portion of the sixth plate, a portion of the first plate, and a portion of the second plate. The seventh plate is disposed within the installation space so that the fourth channel is formed by the arrangement of a portion of the fourth plate, the seventh plate, at least a portion of the sixth plate, a portion of the first plate, and a portion of the second plate. The two ends of the fourth channel can be connected to two first valve ports respectively, or to a first valve port and a connecting port respectively.

[0021] Furthermore, there is a first distance L1 between the fifth plate segment and the central axis of the circular plate, a second distance L2 between the fifth plate and the central axis of the circular plate, and a third distance L3 between the seventh plate and the central axis of the circular plate; wherein L1 = L2 = L3. This arrangement ensures that the flow rates of the first, second, third, and fourth channels are consistent, thereby ensuring that the fluid discharged from the first and second flow holes is consistent and uniform.

[0022] Furthermore, the multiple channels also include a fifth channel and a sixth channel. The first valve core also includes an eighth plate, disposed between and connected to both the first and second plates. The eighth plate, a portion of the first plate, and a portion of the second plate surround to form the fifth channel, and the eighth plate, a fourth plate, a portion of the first plate, and a portion of the second plate surround to form the sixth channel. The eighth plate is disposed within the installation space so that the eighth plate, a portion of the first plate, and a portion of the second plate surround to form the fifth channel, and the eighth plate, a fourth plate, a portion of the first plate, and a portion of the second plate surround to form the sixth channel. The two ends of the fifth channel can be connected to the two first valve ports respectively, or to the first valve port and the connecting port respectively. The two ends of the sixth channel can be connected to the two first valve ports respectively, or to the first valve port and the connecting port respectively.

[0023] Furthermore, the first and second plates are circular plates, and the eighth plate includes: a seventh plate segment extending radially along the circular plate; an eighth plate segment; and a ninth plate segment extending radially along the circular plate and forming a fifth included angle E with the seventh plate segment. The two ends of the eighth plate segment are connected to the seventh and ninth plate segments, respectively. This arrangement ensures that the eighth plate can form the fifth and sixth channels, and also simplifies the structure of the eighth plate, making it easier to process and implement, thus reducing the processing cost of the eighth plate.

[0024] Furthermore, there may be one second valve core; or, there may be multiple second valve cores and multiple connecting ports, with each of the multiple second valve cores corresponding to one of the multiple connecting ports. This configuration allows for greater flexibility in the arrangement of the second valve cores to meet different usage requirements and operating conditions, thus improving the versatility of the control valve; and / or, there may be one first valve core; or, there may be multiple first valve cores, connected to each other via connecting parts.

[0061] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0062] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0063] In this invention, unless otherwise stated, directional terms such as "up" and "down" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0064] To address the problem of complex control of multiple flow paths in existing control valves, this application provides a control valve.

[0065] Example 1

[0066] like Figures 1 to 30 As shown, the control valve includes a valve seat 10, a first valve core 20, and a second valve core 30. The valve seat 10 has a first valve chamber 11, a second valve chamber 17, a connecting port 16, multiple first valve ports 12, and multiple second valve ports 13. The first valve chamber 11 communicates with the multiple first valve ports 12, the second valve chamber 17 communicates with the multiple second valve ports 13, and the first valve chamber 11 is connected to the second valve chamber 17 through the connecting port 16. The first valve core 20 is movably disposed within the first valve chamber 11 and includes multiple channels 21. At least one channel 21 has two ends respectively connected to two first valve ports 12, and at least one first valve port 12 is connected to the connecting port 16 through the channel 21. The second valve core 30 is movably disposed within the second valve chamber 17 and includes a connecting portion 31 for controlling the number of second valve ports 13 connected to the connecting port 16.

[0067] Applying the technical solution of this embodiment, the valve seat 10 has a first valve chamber 11 and a second valve chamber 17, which are connected through a connecting port 16. The control valve includes a first valve core 20 and a second valve core 30. The first valve core 20 is movably disposed within the first valve chamber 11 to control the on / off connection between multiple first valve ports 12 and between the first valve ports 12 and the second valve ports 13. The second valve core 30 is movably disposed within the second valve chamber 17 to control the number of connections between the second valve ports 13 and the connecting port 16, thereby controlling multiple flow paths. Simultaneously, the connecting portion 31 can also be used to regulate the flow rate entering each second valve port 13.

[0068] In this way, compared with the prior art which requires the use of multiple control valves to control multiple flow paths, the control valve in this embodiment can control multiple flow paths simultaneously, thereby reducing the number of control valves used. This solves the problem that the control valves in the prior art are more complex in controlling multiple flow paths, reducing the control difficulty of the fluid system and reducing the manufacturing cost of the system.

[0069] In this embodiment, the control valve further includes a first driving device. The first driving device is driven to rotate the first valve core 20 around its central axis, and multiple first valve ports 12 are spaced apart around the central axis of the first valve core 20. Thus, the first driving device's connection to the first valve core 20 drives its rotation, thereby controlling the interconnection between the multiple first valve ports 12 and between the first valve ports 12 and the second valve ports 13, achieving intelligent control of the control valve.

[0070] In this embodiment, the control valve further includes a second driving device. The second driving device is driven and connected to the second valve core 30 to drive the second valve core 30 to rotate around its central axis. Multiple second valve ports 13 are spaced apart around the central axis of the second valve core 30. Thus, the second driving device's driven connection to the second valve core 30 drives the second valve core 30 to rotate, thereby controlling the interconnection between the multiple second valve ports 13 and between the first valve port 12 and the second valve ports 13, achieving intelligent control of the control valve.

[0071] It should be noted that the number of drive devices included in the control valve is not limited to this and can be adjusted according to the working conditions and usage requirements. In other embodiments not shown in the accompanying drawings, the control valve includes a first drive device and a transmission assembly. The transmission assembly is connected to the drive end of the first drive device and is connected to both the first valve core 20 and the second valve core 30 to drive the first valve core 20 and the second valve core 30 to move synchronously, thereby controlling the on / off state between multiple first valve ports 12, between the first valve port 12 and the second valve port 13, and between multiple second valve ports 13.

[0072] In other embodiments not shown in the accompanying drawings, the control valve includes a second drive device and a transmission assembly. The transmission assembly is connected to the drive end of the second drive device and is connected to both the first valve core 20 and the second valve core 30 to drive the second valve core 30 and the first valve core 20 to move synchronously, thereby controlling the on / off state between multiple first valve ports 12, between the first valve port 12 and the second valve port 13, and between multiple second valve ports 13.

[0073] Specifically, during the process of the driving device driving the first valve core 20 to rotate, the channel 21 can connect multiple first valve ports 12 and the first valve port 12 and the second valve port 13, thereby controlling multiple flow paths.

[0074] In this embodiment, the central axis of the first valve port 12 is parallel to the central axis of the second valve port 13. This arrangement allows the first valve core 20 and the second valve core 30 to be spaced apart along the length or width of the control valve, thereby reducing the overall height and thickness of the control valve.

[0075] In this embodiment, the second valve core 30 can control the flow direction of the fluid flowing from the first valve core 20 into the second valve core 30 and the flow rate ratio of each flow direction.

[0076] In this embodiment, the bottom surface of the valve seat 10 is connected to the mounting component (not shown). Specifically, the bottom surface of the valve seat 10 can be connected to the mounting component through a soft seal, or through laser welding or ultrasonic welding.

[0077] Optionally, there may be one second valve core 30; or, there may be multiple second valve cores 30 and multiple connection ports 16, with each of the multiple second valve cores 30 corresponding to one of the multiple connection ports 16. This arrangement allows for greater flexibility in the configuration of the second valve cores 30, meeting different usage requirements and operating conditions, and improving the versatility of the control valve.

[0078] In this embodiment, there is one connecting port 16 and one second valve core 30, and the second valve core 30 is a three-way valve core.

[0079] like Figure 12 and Figure 14 As shown, the valve seat 10 includes a valve seat body 14 and a surrounding plate 15. The valve seat body 14 has multiple first flow holes 141 and multiple second flow holes 142. The surrounding plate 15 is disposed on the valve seat body 14 and located inside the multiple first flow holes 141 and multiple second flow holes 142. First valve ports 12 and second valve ports 13 are both disposed on the surrounding plate 15. The multiple first flow holes 141 are arranged in a one-to-one correspondence with the multiple first valve ports 12, and the multiple second flow holes 142 are arranged in a one-to-one correspondence with the multiple second valve ports 13. In this way, the first valve ports 12 and second valve ports 13 are both disposed on the surrounding plate 15, and the first flow holes 141 and second flow holes 142 are both disposed on the valve seat body 14. This facilitates the connection of the multiple first valve ports 12 through the channel 21 and the connection of the first valve ports 12 to the second valve ports 13 through the connecting port 16, improving the control reliability of the control valve. Furthermore, it simplifies the structure of the valve seat 10, making it easier to manufacture and implement, and reducing the manufacturing cost of the valve seat 10.

[0080] Specifically, the plurality of first flow holes 141 include a first sub-through hole 1411, a second sub-through hole 1412, a third sub-through hole 1413, a fourth sub-through hole 1414, a sixth sub-through hole 1416, a seventh sub-through hole 1417, and an eighth sub-through hole 1418. The plurality of second flow holes 142 include a fifth sub-through hole 1415 and a ninth sub-through hole 1419. There are seven first valve ports 12, and the seven first valve ports 12 are respectively provided in a one-to-one correspondence with the first sub-through hole 1411, the second sub-through hole 1412, the third sub-through hole 1413, the fourth sub-through hole 1414, the sixth sub-through hole 1416, the seventh sub-through hole 1417, and the eighth sub-through hole 1418. There are two second valve ports 13, and the two second valve ports 13 are respectively provided in a one-to-one correspondence with the fifth sub-through hole 1415 and the ninth sub-through hole 1419. The second valve core 30 has a first connected state where the fifth sub-through hole 1415 and the ninth sub-through hole 1419 are connected, a second connected state where the fifth sub-through hole 1415 is connected to the connecting port 16, and a third connected state where the ninth sub-through hole 1419 is connected to the connecting port 16.

[0081] like Figure 12 As shown, the enclosure 15 includes a first enclosure section 151, a first transition section 152 and a second transition section 153 disposed opposite to each other, and a second enclosure section. The first enclosure section 151 is an arc-shaped section, and a first valve port 12 is disposed on the side wall of the arc-shaped section. The two sides of the arc-shaped section are connected to the first transition section 152 and the second transition section 153 respectively, forming a communication port 16 between the first transition section 152 and the second transition section 153. The second enclosure section surrounds and forms a second valve cavity 17. This arrangement simplifies the structure of the enclosure 15, making it easier to manufacture and implement, and reducing the manufacturing cost of the enclosure 15.

[0082] In this embodiment, the enclosure 15 is a one-piece molded structure.

[0083] like Figure 12 As shown, the second enclosure panel segment includes a first panel segment 154, a second panel segment 155, and a third panel segment 156. One side of the first panel segment 154 is connected to the first transition panel segment 152. One side of the third panel segment 156 is connected to the second transition panel segment 153 and is positioned opposite to the first panel segment 154. Both sides of the second panel segment 155 are connected to the first panel segment 154 and the third panel segment 156, respectively. A second valve port 13 is provided on the first panel segment 154 and / or the third panel segment 156. This arrangement simplifies the structure of the second enclosure panel segment, making it easier to manufacture and implement, and reducing the manufacturing cost of the second enclosure panel segment.

[0084] In this embodiment, there are two second valve ports 13, which are respectively disposed on the first plate segment 154 and the third plate segment 156. The second plate segment 155 is disposed opposite to the connecting port 16. The first transition plate segment 152 and the second transition plate segment 153 are disposed opposite to each other and are in a trumpet shape.

[0085] In this embodiment, the first flow hole 141 is a fan-shaped hole. In this way, the above-mentioned configuration increases the area of ​​the first flow hole 141, thereby improving the flow efficiency of the control valve; on the other hand, it makes the structure of the first flow hole 141 simpler, easier to process and implement, and reduces the processing cost of the control valve.

[0086] like Figure 3 , Figures 7 to 9 As shown, the control valve also includes a first sealing structure 50. The first sealing structure 50 is disposed between the first enclosure plate segment 151 and the first valve core 20. The first sealing structure 50 has multiple first through holes 51, each corresponding to a plurality of first valve ports 12. Thus, the first sealing structure 50 seals the space between the first enclosure plate segment 151 and the first valve core 20 to prevent fluid leakage to the outside of the first valve ports 12. Optionally, the first sealing structure 50 is arc-shaped and also has an opening opposite to the connecting port 16.

[0087] In this embodiment, there are seven first through holes 51, and the seven first through holes 51 are arranged one-to-one with the seven first valve ports 12. The seven first through holes 51 are spaced apart around the central axis of the first sealing structure 50.

[0088] Optionally, the control valve further includes a second sealing structure 60. The second sealing structure 60 is disposed between the second enclosure plate segment and the second valve core 30. The second sealing structure 60 has a second through hole 61, through which the communicating portion 31 communicates with the second valve port 13. Thus, the second sealing structure 60 is used to seal the space between the second enclosure plate segment and the second valve core 30 to prevent fluid leakage to the outside of the second valve port 13. Optionally, the second sealing structure 60 is annular.

[0089] In this embodiment, there are two second sealing structures 60, each corresponding to one of the two second valve ports 13. Thus, when the second valve core 30 is in the first flow state, fluid can enter the connecting portion 31 through the connecting port 16, and then flow into the two second valve ports 13 through the two second through holes 61 respectively; when the second valve core 30 is in the second flow state, fluid can enter the connecting portion 31 through the connecting port 16, and then flow into one second valve port 13 through a second through hole 61 corresponding to the fifth sub-through hole 1415; when the second valve core 30 is in the third flow state, fluid can enter the connecting portion 31 through the connecting port 16, and then flow into one second valve port 13 through a second through hole 61 corresponding to the ninth sub-through hole 1419.

[0090] like Figures 4 to 6As shown, the multiple channels 21 include a first channel 211, and the first valve core 20 also includes a first plate 22, a second plate 23, and a third plate 24. The second plate 23 is disposed opposite to the first plate 22. The third plate 24 is disposed between the first plate 22 and the second plate 23 and is connected to both the first plate 22 and the second plate 23. The third plate 24, a portion of the first plate 22, and a portion of the second plate 23 surround to form the first channel 211. Thus, an installation space is formed between the first plate 22 and the second plate 23, and the third plate 24 is disposed within the installation space, so that the third plate 24, a portion of the first plate 22, and a portion of the second plate 23 surround to form the first channel 211. The two ends of the first channel 211 can be connected to two first valve ports 12 respectively, or to a first valve port 12 and a connecting port 16 respectively.

[0091] like Figure 8 , Figure 15 , Figure 17 , Figure 19 , Figure 21 , Figure 23 , Figure 25 , Figure 27 and Figure 29 As shown, the first channel 211 includes a first sub-channel 2111 and a second sub-channel 2112, the second channel 212 includes a third sub-channel 2121 and a fourth sub-channel 2122, the third channel 213 includes a fifth sub-channel 2131 and a sixth sub-channel 2132, and the fourth channel 214 includes a seventh sub-channel 2141 and an eighth sub-channel 2142.

[0092] like Figures 4 to 6 As shown, the first plate 22 and the second plate 23 are circular plates, and the third plate 24 includes a fourth plate segment 241, a fifth plate segment 242, and a sixth plate segment 243. The fourth plate segment 241 extends radially along the circular plate. The sixth plate segment 243 extends radially along the circular plate and is positioned at a first angle A with the fourth plate segment 241. The two ends of the fifth plate segment 242 are connected to the fourth plate segment 241 and the sixth plate segment 243, respectively. This arrangement ensures that the third plate 24 can form the first channel 211, and also simplifies the structure of the third plate 24, making it easier to process and implement, and reducing the processing cost of the third plate 24.

[0093] Optionally, the first included angle A satisfies: The number of channels 21 is n. In this embodiment, n is four, and the first included angle A is 90°.

[0094] like Figures 4 to 6As shown, the multiple channels 21 also include a second channel 212, and the first valve core 20 also includes a fourth plate 25. The fourth plate 25 is disposed between and connected to both the first plate 22 and the second plate 23, and is spaced apart from the fifth plate segment 242. The second channel 212 is formed by the fourth plate 25, a portion of the first plate 22, a portion of the second plate 23, and the third plate 24. Thus, the fourth plate 25 is disposed within the installation space so that the second channel 212 is formed by the fourth plate 25, a portion of the first plate 22, a portion of the second plate 23, and the third plate 24. The two ends of the second channel 212 can be connected to the two first valve ports 12 respectively, or to the first valve port 12 and the connecting port 16 respectively.

[0095] Optionally, the fourth plate 25 and the fifth plate segment 242 are arranged parallel to each other; and / or, the fourth plate 25 passes through the central axis of the second plate 23. In this way, the above arrangement makes the arrangement of the fourth plate 25 more flexible to meet different usage requirements and working conditions.

[0096] In this embodiment, the fourth plate 25 and the fifth plate segment 242 are arranged parallel to each other.

[0097] like Figures 4 to 6 As shown, the plurality of channels 21 also includes a third channel 213, and the first valve core 20 also includes a fifth plate 26 and a sixth plate 27. The fifth plate 26 is disposed between the first plate 22 and the second plate 23 and is connected to both the first plate 22 and the second plate 23. One end of the fifth plate 26 is connected to the fourth plate 25 and is positioned at a second included angle B with the fourth plate 25. The sixth plate 27 is disposed between the first plate 22 and the second plate 23 and is connected to both the first plate 22 and the second plate 23. The sixth plate 27 extends radially along the circular plate and is connected to the other end of the fifth plate 26. The sixth plate 27 is positioned at a third included angle C with the fourth plate 25. The third channel 213 is formed by the surrounding arrangement of a portion of the fourth plate 25, the fifth plate 26, at least a portion of the sixth plate 27, a portion of the first plate 22, and a portion of the second plate 23. Thus, the fifth plate 26 and the sixth plate 27 are both disposed within the installation space, so that a third channel 213 is formed by the partial fourth plate 25, the fifth plate 26, at least a partial sixth plate 27, a partial first plate 22, and a partial second plate 23. The two ends of the third channel 213 can be connected to the two first valve ports 12 respectively, or they can be connected to the first valve port 12 and the connecting port 16 respectively.

[0098] Alternatively, the second included angle B satisfies: The third included angle C satisfies: The number of channels 21 is n. In this embodiment, the second included angle B is 45° and the third included angle C is 90°.

[0099] like Figures 4 to 6 As shown, the multiple channels 21 also include a fourth channel 214, and the first valve core 20 also includes a seventh plate 28. The seventh plate 28 is disposed between the first plate 22 and the second plate 23 and is connected to both the first plate 22 and the second plate 23. The two ends of the seventh plate 28 are respectively connected to the fourth plate 25 and the sixth plate 27, and the seventh plate 28 and the fourth plate 25 are arranged at a fourth included angle D. The fourth channel 214 is formed by the partial fourth plate 25, the seventh plate 28, at least a partial sixth plate 27, a partial first plate 22, and a partial second plate 23. Thus, the seventh plate 28 is disposed within the installation space so that the fourth channel 214 is formed by the partial fourth plate 25, the seventh plate 28, at least a partial sixth plate 27, a partial first plate 22, and a partial second plate 23. The two ends of the fourth channel 214 can be connected to the two first valve ports 12 respectively, or connected to the first valve port 12 and the connecting port 16 respectively.

[0100] Alternatively, the fourth included angle D satisfies: The number of channels 21 is n. In this embodiment, the fourth included angle D is 90°.

[0101] like Figure 6 As shown, the fifth plate segment 242 has a first distance L1 between it and the central axis of the circular plate, the fifth plate 26 has a second distance L2 between it and the central axis of the circular plate, and the seventh plate 28 has a third distance L3 between it and the central axis of the circular plate. Wherein, L1 = L2 = L3. This arrangement ensures that the flow rates of the first channel 211, the second channel 212, the third channel 213, and the fourth channel 214 are consistent, guaranteeing that the fluid discharged from the first flow hole 141 and the second flow hole 142 is consistent and uniform.

[0102] Optionally, the number of first valve ports 12 is 2n-1, and the number of channels 21 is n. In this embodiment, there are four channels 21 and seven first valve ports 12.

[0103] Specifically, the first valve core 20 rotates at a gradient of 45° to achieve 8 flow modes at the first flow orifice 141. The second valve core 30 rotates to achieve 3 flow modes at the second flow orifice 142, thus the control valve can achieve a total of 24 flow modes. The second valve core 30 cooperates with two second sealing structures 60 to form a tenth sub-channel 32, a ninth sub-channel 62, and an eleventh sub-channel 63. When the second valve core 30 is in the first connected state, the tenth sub-channel 32, the ninth sub-channel 62, and the eleventh sub-channel 63 are interconnected; when the second valve core 30 is in the second connected state, the eleventh sub-channel 63 is connected to the tenth sub-channel 32, and the tenth sub-channel 32 is disconnected from the ninth sub-channel 62; when the second valve core 30 is in the third connected state, the eleventh sub-channel 63 is disconnected from the tenth sub-channel 32, and the tenth sub-channel 32 is connected to the ninth sub-channel 62.

[0119] When the second valve core 30 rotates 90° counterclockwise, the second sub-through hole 1412 and the third sub-through hole 1413 are connected, the fourth sub-through hole 1414 and the seventh sub-through hole 1417 are connected, the first sub-through hole 1411 and the eighth sub-through hole 1418 are connected, and the sixth sub-through hole 1416 and the ninth sub-through hole 1419 are connected; when the second valve core 30 rotates 90° clockwise, the second sub-through hole 1412 and the third sub-through hole 1413 are connected, the fourth sub-through hole 1414 and the seventh sub-through hole 1417 are connected, the first sub-through hole 1411 and the eighth sub-through hole 1418 are connected, and the sixth sub-through hole 1416 and the fifth sub-through hole 1415 are connected.

[0120] like Figure 1 As shown, the control valve also includes a valve cover 40, which covers the valve seat 10 to protect the first valve core 20 and the second valve core 30.

[0121] Optionally, there may be one second valve core 30; or, there may be multiple second valve cores 30 and multiple connecting ports 16, with each of the multiple second valve cores 30 corresponding to one of the multiple connecting ports 16; and / or, there may be one first valve core 20; or, there may be multiple first valve cores 20, which are connected to each other via connecting parts 31. In this way, the above configuration allows the control valve to further control multiple flow paths to meet different usage requirements and operating conditions, and also improves the versatility of the control valve.

[0122] In this embodiment, there is one first valve core 20 and one second valve core 30, so that the structure of the control valve is simpler, easier to process and implement, and the processing cost of the control valve is reduced.

[0123] It should be noted that the number of second valve cores 30 is not limited to this and can be adjusted according to operating conditions and usage requirements. Optionally, there may be two, three, four, or more second valve cores 30.

[0124] It should be noted that the number of first valve cores 20 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, three, four, or more first valve cores 20.

[0125] Example 2

[0126] The difference between the control valve in Example 2 and Example 1 is that the structure of the first valve core 20 is different.

[0127] like Figure 31 As shown, the multiple channels 21 also include a fifth channel 215 and a sixth channel 216, and the first valve core 20 also includes an eighth plate 29. The eighth plate 29 is disposed between and connected to both the first and second plates 22 and 23. The eighth plate 29, a portion of the first plate 22, and a portion of the second plate 23 surround to form the fifth channel 215, and the eighth plate 29, a fourth plate 25, a portion of the first plate 22, and a portion of the second plate 23 surround to form the sixth channel 216. Thus, the eighth plate 29 is disposed within the installation space, such that the eighth plate 29, a portion of the first plate 22, and a portion of the second plate 23 surround to form the fifth channel 215, and the eighth plate 29, the fourth plate 25, a portion of the first plate 22, and a portion of the second plate 23 surround to form the sixth channel 216. The two ends of the fifth channel 215 can be connected to the two first valve ports 12 respectively, or to the first valve port 12 and the connecting port 16 respectively. The two ends of the sixth channel 216 can be connected to the two first valve ports 12 respectively, or they can be connected to the first valve port 12 and the connecting port 16 respectively.

[0128] like Figure 31 As shown, the first plate 22 and the second plate 23 are circular plates, and the eighth plate 29 includes a seventh plate segment 291, an eighth plate segment 292, and a ninth plate segment 293. The seventh plate segment 291 extends radially along the circular plate. The ninth plate segment 293 extends radially along the circular plate and forms a fifth angle E with the seventh plate segment 291. The two ends of the eighth plate segment 292 are connected to the seventh plate segment 291 and the ninth plate segment 293, respectively. This arrangement ensures that the eighth plate 29 can form the fifth channel 215 and the sixth channel 216, and also simplifies the structure of the eighth plate 29, making it easier to manufacture and implement, and reducing the manufacturing cost of the eighth plate 29.

[0129] Alternatively, the fifth included angle E satisfies: The number of channels 21 is n. In this embodiment, n is four, and the fifth included angle E is 90°.

[0130] Example 3

[0131] The difference between the control valve in Example 3 and Example 1 is that the structure of the first valve core 20 is different.

[0132] like Figure 32 and Figure 33 As shown, the multiple channels 21 also include a seventh channel 74 and an eighth channel 75. The first valve core 20 also includes a ninth plate 70, which is disposed between and connected to both the first plate 22 and the second plate 23. The ninth plate 70, a portion of the first plate 22, a portion of the second plate 23, and the third plate 24 surround to form the seventh channel 74, and the ninth plate 70, a portion of the first plate 22, and a portion of the second plate 23 surround to form the eighth channel 75. Thus, the ninth plate 70 is disposed within the installation space. The two ends of the seventh channel 74 can be connected to the two first valve ports 12 respectively, or to the first valve port 12 and the connecting port 16 respectively. The two ends of the eighth channel 75 can be connected to the two first valve ports 12 respectively, or to the first valve port 12 and the connecting port 16 respectively.

[0133] like Figure 32 As shown, the ninth plate 70 includes a tenth plate segment 71, an eleventh plate segment 72, and a twelfth plate segment 73. The tenth plate segment 71 extends radially along the circular plate. The twelfth plate segment 73 extends radially along the circular plate and forms a predetermined angle with the tenth plate segment 71. The two ends of the eleventh plate segment 72 are connected to the tenth plate segment 71 and the twelfth plate segment 73, respectively. This arrangement ensures that the ninth plate 70 can form the eighth channel 75, and also simplifies the structure of the ninth plate 70, making it easier to manufacture and implement, and reducing the manufacturing cost of the ninth plate 70.

[0134] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0135] The valve seat has a first valve chamber and a second valve chamber, which are connected by a connecting port. The control valve includes a first valve core and a second valve core. The first valve core is movably disposed within the first valve chamber to control the on / off connection between multiple first valve ports and between the first and second valve ports. The second valve core is movably disposed within the second valve chamber to control the number of second valve ports connected to the connecting port, thereby controlling multiple flow paths. Simultaneously, the connecting portion can also be used to regulate the flow rate entering each second valve port.

[0136] In this way, compared with the prior art which requires the use of multiple control valves to control multiple flow paths, the control valve in this application can control multiple flow paths simultaneously, thereby reducing the number of control valves used. This solves the problem that the control valves in the prior art are relatively complex to control multiple flow paths, reduces the control difficulty of the fluid system and reduces the manufacturing cost of the system.
