Description

Technical Field

[0001] This invention relates to the field of valves, and in particular to a multi-way valve and a method for adjusting the valve core position of a multi-way valve. Background Technology

[0002] Currently, in the thermal management applications of new energy vehicles, butterfly valves, ball valves, and column valves are commonly used for water valves. This approach is used to switch, combine, and divide the coolant. However, the fluid flow direction of these valves is mainly controlled by the valve core, and the irregular arrangement of the flow channels leads to chaotic pipe layouts and problems with the installation of actuators and other components. Furthermore, because the valve body needs to be designed according to the valve core, the valve's applicability is poor.

[0003] To solve the above problems, the existing approach is to integrate all the flow ports of the valve into one side of the valve body, and this side is flat, which facilitates the pipe layout of the components and the design of the flow channels. The problem is that after the fluid passes through the valve core, the valve core is pressurized on one side, resulting in uneven force. This can easily lead to excessive local friction of the valve core or seals, causing wear, or leakage due to valve core tilting. Summary of the Invention

[0004] The main technical problem solved by this invention is to address the issue of uneven force distribution on the valve core of a disc valve due to pressure on only one side.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A multi-way valve is provided, comprising: a valve body, a valve core, and a valve cover, wherein the valve body is provided with an inner cavity for mounting the valve core, and the valve core is rotatably mounted in the inner cavity;

[0007] Along the axial direction of the valve core, the valve body has end face A and end face B; the valve cover is mounted on end face A of the valve body, and the valve cover is provided with a plurality of flow channels;

[0008] The valve core includes: valve core A near end face A and valve core B near end face B, and both valve core A and valve core B are provided with several valve core flow channels that are not interconnected.

[0009] The present invention also provides a multi-way valve, the multi-way valve comprising a valve body and a valve core, the valve core being rotatably disposed within the valve body.

[0010] The valve core includes valve core A and valve core B. Both valve core A and valve core B are provided with a plurality of valve core flow channels. One end of the valve body is provided with a flow channel opening that communicates with the valve core flow channels of valve core A and valve core B respectively.

[0011] As a further improvement of the present invention, valve core A and valve core B are arranged symmetrically.

[0012] As a further improvement of the present invention, valve core A and valve core B are separately disposed, and the valve core further includes: a transmission component for driving valve core A and valve core B to move together, wherein one of valve core A and valve core B is an active valve core and the other is a driven valve core.

[0013] As a further improvement of the present invention, the flow channel includes an inner flow channel and an outer flow channel, the inner flow channel and the outer flow channel are disposed at one end of the valve body along the axial direction, and the outer flow channel is disposed radially outside the inner flow channel.

[0014] As a further improvement of the present invention, each of the valve core flow channels is connected to at least two flow ports, and the valve body is provided with a valve body flow channel for connecting the external flow port and the valve core B.

[0015] As a further improvement of the present invention, valve core A and valve core B are connected by bearings.

[0016] As a further improvement of the present invention, the bearing is a one-way bearing, which is the transmission assembly. The valve core A and the valve core B are respectively connected to the two rings of the one-way bearing, so that when the active valve core of the valve core A and the valve core B rotates in one direction, it drives the driven valve core to rotate, and when the active valve core rotates in the other direction, it does not drive the driven valve core to rotate.

[0017] As a further improvement of the present invention, a drive shaft is provided in the valve body, and the drive shaft is poweredly connected to valve core A and / or valve core B; the drive shaft can be integrated with valve core A and / or valve core B or can be provided separately.

[0018] Of the valve cores A and B, one is the active valve core and the other is the driven valve core, which is poweredly connected to the transmission shaft. The active valve core drives the driven valve core to rotate through the transmission assembly.

[0019] As a further improvement of the present invention, the transmission assembly is composed of at least one set of structural components, each set of structural components including at least two structural members, the two structural members being respectively disposed on the active valve core and the driven valve core, such that one of the structural members can contact the other structural member during the rotation of the active valve core, and after the two structural members contact each other, the active valve core can drive the driven valve core to rotate.

[0020] As a further improvement of the present invention, the structural component consists of two blocking blocks, which are respectively fixedly connected to or integrated with the active valve core and the driven valve core.

[0021] As a further improvement of the invention, one of the blocking blocks is disposed in an annular groove on the active valve core / the driven valve core.

[0022] As a further improvement of the present invention, the transmission assembly consists of a ratchet and several spring plates. One end of each spring plate engages with the ratchet, such that when the active valve core rotates in one direction, it drives the driven valve core to rotate, and when the active valve core rotates in another direction, it does not drive the driven valve core to rotate.

[0023] As a further improvement of the present invention, the transmission assembly includes a rotatable lever and a spring plate, the spring plate applying a force toward the ratchet to the lever.

[0024] As a further improvement of the present invention, the multi-way valve also includes a valve cover, which is installed on one end face of the valve body, and a plurality of flow ports are provided on the valve cover.

[0025] The present invention also provides a method for adjusting the valve core position of a multi-way valve as described above, comprising the following steps:

[0026] S1: Provide a multi-way valve, wherein one of the valve cores A and B is an active valve core and the other is a driven valve core;

[0027] S2: Drive the active valve core to rotate until the active valve core abuts against the driven valve core;

[0028] S3: Continue to drive the active valve core to rotate until the driven valve core reaches the set position;

[0029] S4: Drive the active valve core to rotate in the reverse direction until the active valve core reaches the set position.

[0030] The beneficial effects of this invention are:

[0031] 1. In this application, by setting two symmetrical valve cores in the valve body, when the multi-way valve is in use, the flow channels in the first valve core and the second valve core are both subjected to fluid pressure, and the pressure is directed in opposite directions, which reduces the overall force on the valve core and solves the problem of pressure on one side of the disc valve. Setting the flow channel opening on the same side can facilitate the installation of the hand parts.

[0032] 2. In this application, the two valve cores are connected by a bearing to reduce friction and increase coaxiality. Furthermore, a transmission assembly is provided between the two valve cores, which can transmit power so that the transmission shaft only needs to be connected to one valve core to drive the two valve cores to rotate.

[0033] 3. In this application, since the valve core is composed of two parts, valve core A and valve core B, each valve core has several flow channels and the valve body has several flow port. The number of flow ports that can be connected to external pipelines can be selected according to the actual situation, while other flow ports are sealed. Therefore, the valve has good compatibility.

[0034] 4. In this application, since the valve core is composed of two parts, valve core A and valve core B, the number of flow channels that can be set in the valve core is greater, the applicability is wider, and the selectivity of flow channels is increased, which facilitates the design of flow channel passages.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1:

[0046] See Figure 1 A multi-port valve includes: a valve body 1, a valve core 2, and a valve cover 3. The valve body 1 has an inner cavity 8, the valve core 2 is rotatably installed in the inner cavity 8, and the valve cover 3 is fixedly installed on the valve body 1.

[0047] See Figure 2 Along the axial direction of the valve core 2, the valve body 1 has end face A and end face B;

[0048] The valve cover 3 is installed on the end face A of the valve body and is provided with a plurality of flow channels 31. A sealing element 4 is provided between the valve cover 3, the valve body 1, and the valve core 2.

[0049] The valve core 2 includes: a valve core A21 near end face A, a valve core B22 near end face B, and a transmission assembly for driving the valve core 21A and the valve core B22 to move together. The valve core A21 and the valve core B22 are provided with a number of valve core flow channels that are not interconnected. Each valve core flow channel is connected to at least two flow channel ports 31. Correspondingly, the valve body 1 is also provided with a valve body flow channel 9 for connecting the flow channel ports 31 and the valve core B22.

[0050] See appendix Figure 1-2The flow channels include internal flow channels and external flow channels. Each external flow channel is provided on the valve cover 3, and several internal flow channels 32 are distributed on the valve cover 3 corresponding to the valve core 2. The number of internal flow channels 32 is the same as the number of external flow channels 31.

[0051] The valve core A21 and the valve core B22 are separately arranged. A bearing 5 is arranged between the valve core A21 and the valve core B22. A positioning shaft 6 is arranged on the top of the valve core B22. A cavity for accommodating the bearing 5 is arranged at the bottom of the valve core A21. The cavity is interference-fitted with the outer ring of the bearing 5, and the positioning shaft 6 is interference-fitted with the inner ring of the bearing 5.

[0052] Furthermore, a drive shaft 7 is installed below the valve body 1, and the drive shaft 7 is poweredly connected to the valve core B22. The transmission assembly is provided between the valve core A21 and the valve core B22 to transmit power between the valve core A21 and the valve core B22.

[0053] The drive shaft 7 can also be mounted on the valve cover 3 and poweredly connected to the valve core A21;

[0054] The drive shaft 7 can be installed independently or integrated with valve core A21 or valve core B22.

[0055] Of the valve cores A and B, one is the driving valve core, and the other is the driven valve core, which is poweredly connected to the drive shaft. The driving valve core drives the driven valve core to rotate through a transmission assembly. In the following embodiments, valve core B22 is the driving valve core, and valve core A21 is the driven valve core.

[0056] The transmission assembly consists of at least one set of structural components. Each set of structural components includes at least two structural members, which are respectively disposed on the active valve core and the driven valve core, such that one structural member can contact the other structural member during the rotation of the active valve core, and after the two structural members contact each other, the active valve core can drive the driven valve core to rotate.

[0057] See Figure 3 and Figure 4 The transmission assembly consists of a blocking block A211 and a blocking block B221, which are respectively disposed on the valve core A21 and the valve core B22. In addition, to reduce space, the blocking block A211 is disposed in an annular groove on the valve core A21. When the valve core A21 rotates, the blocking block B221 moves relative to it in the annular groove. When the two blocking blocks touch, the valve core A21 can drive the valve core B22 to rotate.

[0058] In actual use, first rotate valve core B22 in one direction. When the two blocking blocks touch, adjust the angle position of valve core A21. After valve core A21 is in position, rotate valve core B22 in the opposite direction to adjust the angle position of valve core B22.

[0059] Example 2:

[0060] The transmission component in Embodiment 1 can be a one-way bearing. Accordingly, a one-way bearing is used instead of bearing 5 in Embodiment 1, so that when valve core A21 rotates in one direction, it can drive valve core B22 to rotate, and when valve core A21 rotates in another direction, it will not drive valve core B22 to rotate.

[0061] Example 3:

[0062] See Figure 5 In Embodiment 1, the transmission assembly can be composed of a ratchet 26 and several spring plates 25. The spring plates 25 are evenly arranged in a ring on the valve core B22, and the ratchet 26 is fixedly arranged on the valve core A21. The ratchet 26 cooperates with the spring plates 25 so that when the valve core A21 rotates in one direction, it can drive the valve core B22 to rotate, and when the valve core A21 rotates in another direction, it will not drive the valve core B22 to rotate.

[0063] Example 4:

[0064] See Figure 6 In embodiment 3, the transmission assembly includes a rotatable lever 27 and a spring 25. The spring 25 applies a force toward the ratchet 26 to the lever 27 to ensure the engagement of the lever 27 and the ratchet 26.

[0065] A method for adjusting the valve core position of a multi-way valve includes the following steps:

[0066] S1: A multi-way valve 100 is provided, wherein one of the valve cores A21 and B22 is an active valve core and the other is a driven valve core;

[0067] S2: Drive the active valve core to rotate until the active valve core and the driven valve core abut against each other;

[0068] S3: Continue to drive the active valve core to rotate until the driven valve core reaches the set position;

[0069] S4: Reverse drive the active valve core to rotate until the active valve core reaches the set position.

[0070] This method of adjusting the valve core position of a multi-way valve allows for separate adjustment of the positions of the active valve core and the driven valve core.

[0071] In this application, by setting two symmetrical valve cores in the valve body 1, when the multi-way valve is in use, the flow channels in the first valve core 21 and the second valve core 22 are both subjected to fluid pressure, and the pressure is directed in opposite directions, which reduces the overall force on the valve core 2, solves the problem of pressure on one side of the disc valve, and sets the flow channel opening on the same side, which facilitates the installation of the hand parts.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
