[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] like Figure 1-Figure 18 As shown, an embodiment of the present application provides a valve device, including a housing 1 and a valve core assembly, wherein the housing 1 has an inlet 11 and multiple outlets, such as two, three or four outlets, preferably two outlets, so that the valve device forms a three-way valve. The valve core assembly is arranged inside the housing 1, and the valve core assembly is located between the inlet 11 and the outlet, so that the inlet 11 is connected to the multiple outlets respectively through the valve core assembly in the inner cavity to achieve flow diversion.

[0048] The valve core assembly includes a fixed valve member 2 and a movable valve member 3, wherein the movable valve member 3 is rotatably arranged in the housing 1, and the fixed valve member 2 is fixed in the housing 1 so that the movable valve member 3 can rotate along the first axis relative to the fixed valve member 2. The movable valve member 3 is close to the inlet 11 of the housing 1, and a plurality of movable valve member flow channels are arranged on the movable valve member 3, and the movable valve member flow channels are connected with the inlet 11. The fixed valve member 2 is close to the outlet of the housing 1, and a plurality of fixed valve member flow channels are arranged on the fixed valve member 2, and the number of the plurality of fixed valve member flow channels is consistent with the number of the plurality of outlets, and the plurality of fixed valve member flow channels are connected with the plurality of outlets one-to-one, for example, the fixed valve member flow channels are arranged with two, three or four, and preferably two are arranged here. Here, the fixed valve member 2 is arranged as a valve block, and the movable valve member 3 is arranged as a valve sheet.

[0049] During the rotation of the movable valve member 3 relative to the fixed valve member 2, the plurality of fixed valve member flow channels cooperate with the plurality of movable valve member flow channels, and the fluid channels connecting the movable valve member flow channels and the fixed valve member flow channels are connected to form a fluid channel connecting the inlet 11 and the outlet of the housing 1. Here, the plurality of fixed valve member flow channels and the plurality of movable valve member flow channels cooperate to form at least two fluid channels, one end of the two fluid channels is connected to the inlet 11, and the other end is connected to the two outlets respectively, so that the two fluid channels formed by cooperation can realize the diversion of the fluid. Moreover, when the rotation angle of the movable valve member 3 is within the preset range, the flow rate of one of the fluid channels remains unchanged, and the flow rate of the other fluid channel increases or decreases as the rotation angle of the movable valve member 3 changes.

[0050] It should be noted that, in the above, the flow rate of one fluid channel remains unchanged, which can be either zero or a fixed value. That is, when the flow rate of one fluid channel is adjusted separately, the flow rate of another fluid channel can be zero or a fixed value.

[0051] With such arrangement, the flow rates of different fluid channels can be flexibly controlled by controlling the rotation angle of the movable valve member 3, and only one valve device is required to realize independent regulation of a single fluid channel, which has a simple structure, low processing cost and is easy to control.

[0052] In this solution, the valve device is configured as a three-way valve, and the housing 1 is provided with an inlet 11 and two outlets, the two outlets are respectively a first outlet 12 and a second outlet 13, and the fixed valve member 2 is provided with two fixed valve member flow passages, respectively a first fixed valve member flow passage 21 and a second fixed valve member flow passage 22, the first outlet 12 is communicated with the first fixed valve member flow passage 21, and the second outlet 13 is communicated with the second fixed valve member flow passage 22. The movable valve member 3 is provided with two movable valve member flow passages, respectively a first movable valve member flow passage 31 and a second movable valve member flow passage 32, and the first movable valve member flow passage 31 and the second movable valve member flow passage 32 are both communicated with the inlet 11. Among them, at least one of the first movable valve member flow passage 31 and the second movable valve member flow passage 32 cooperates with the first fixed valve member flow passage 21 to form a first fluid channel, and at least one of the first movable valve member flow passage 31 and the second movable valve member flow passage 32 cooperates with the second fixed valve member flow passage 22 to form a second fluid channel. When the rotation angle of the movable valve member 3 is within a preset range, the flow rate of the first fluid channel remains unchanged, and the flow rate of the second fluid channel increases or decreases with the change of the rotation angle of the movable valve member 3. In this way, the flow rate of a single fluid channel can be independently adjusted through the cooperation of two flow channels and two movable valve member flow channels, with a simple structure, safety and stability.

[0053] It should be noted that, in a specific solution, the first fixed valve member flow channel 21 can cooperate with the first movable valve member flow channel 31 to form a first fluid channel, and the second fixed valve member flow channel 22 can cooperate with the second movable valve member flow channel 32 to form a second fluid channel; or both the first movable valve member flow channel 31 and the second movable valve member flow channel 32 can be connected and cooperated with the first fixed valve member flow channel 21 to form a first fluid channel, and both the first movable valve member flow channel 31 and the second movable valve member flow channel 32 can be connected and cooperated with the second fixed valve member flow channel 22 to form a second fluid channel. The actual situation depends on the rotation angle of the movable valve member 3, and what remains unchanged is that the first fixed valve member flow channel 21 corresponds to the first fluid channel, and the second fixed valve member flow channel 22 corresponds to the second fluid channel.

[0054] Of course, in other schemes, the valve device can also be configured as a four-way valve, that is, an inlet 11 and three outlets can be set on the shell 1, three flow channels can be set on the fixed valve member 2, and two movable valve member flow channels can be set on the movable valve member 3. Through the cooperation of the two movable valve member flow channels and the three flow channels, two fluid channels are formed at the same time.

[0055] The flow channel opening of the first fixed valve member flow channel 21 and the flow channel opening of the second fixed valve member flow channel 22 are arranged at a distance along the direction around the first axis, and the flow channel opening of the first movable valve member flow channel 31 and the flow channel opening of the second movable valve member flow channel 32 are arranged at a distance along the direction around the first axis. For the convenience of description, in this article, the flow channel opening of the first fixed valve member flow channel 21 is defined as the first flow channel opening 23, and the flow channel opening of the second fixed valve member flow channel 22 is defined as the second flow channel opening 24, that is, the first flow channel opening 23 and the second flow channel opening 24 are arranged at a distance along the direction around the first axis; the flow channel opening on the first movable valve member flow channel 31 is defined as the third flow channel opening 33, and the flow channel opening on the second movable valve member flow channel 32 is defined as the fourth flow channel opening 34, and the third flow channel opening 33 and the fourth flow channel opening 34 are arranged at a distance along the direction around the first axis. Moreover, the first flow channel opening 23 and the second flow channel opening 24 are located on a side of the fixed valve component 2 close to the movable valve component 3, and the third flow channel opening 33 and the fourth flow channel opening 34 are located on a side of the movable valve component 3 close to the fixed valve component 2, so that the first flow channel opening 23 and the second flow channel opening 24 on the fixed valve component 2 can cooperate with the third flow channel opening 33 and the fourth flow channel opening 34 on the movable valve component 3.

[0056] During the rotation of the movable valve member 3 relative to the fixed valve member 2, the flow channel opening (first flow channel opening 23) of the first fixed valve member flow channel 21 and the flow channel opening (second flow channel opening 24) of the first movable valve member flow channel 31 can be connected and cooperate to form a first valve opening, and the flow rate of the first fluid channel can be controlled by controlling the opening size of the first valve opening. At the same time, the flow channel opening (third flow channel opening 33) of the second fixed valve member flow channel 22 and the flow channel opening (fourth flow channel opening 34) of the second movable valve member flow channel 32 can be connected and cooperate to form a second valve opening, and the flow rate of the second fluid channel can be controlled by controlling the opening size of the second valve opening. When the rotation angle of the movable valve member 3 is within the preset range, the opening of the first valve opening remains unchanged, and the opening of the second valve opening increases or decreases with the change of the rotation angle of the movable valve member 3. In this way, when the rotation angle of the movable valve member 3 is within a preset range, the first flow channel opening 23 and the third flow channel opening 33 cooperate separately, and the second flow channel opening 24 and the fourth flow channel opening 34 cooperate separately, so that the first valve opening and the second valve opening formed are tightly matched, the structure is simple and reliable, and the stability is strong.

[0057] In some preferred embodiments, the first flow channel opening 23 is larger than the third flow channel opening 33. Thus, when the rotation angle of the movable valve member 3 is within a preset range, the third flow channel opening 33 can always be completely within the range of the first flow channel opening 23, so that the opening of the first valve opening formed by the first flow channel opening 23 and the third flow channel opening 33 remains unchanged.

[0058] The minimum distance between the first flow channel opening 23 and the second flow channel opening 24 is less than or equal to the maximum distance between the two sides of the fourth flow channel opening 34 along the rotation direction around the first axis. In this way, the fourth flow channel opening 34 can be located in the interval area between the first flow channel opening 23 and the second flow channel opening 24, and thus the fourth flow channel opening 34 is in a closed state. At this time, the opening of the second valve port formed by the fourth flow channel opening 34 and the second flow channel opening 24 is zero. When the rotation angle of the movable valve member 3 is within the preset range, the opening of the second valve port can increase from zero or gradually decrease to zero, thereby reasonably controlling the opening range of the second valve port.

[0059] The following is a detailed description of the two embodiments of this solution in conjunction with the specific solutions.

[0060] like Figure 3-10 As shown, in the first embodiment, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 are all generally arc-shaped. Specifically, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 are all located on the first circumference, and the center of the first circumference is located on the first axis, that is, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 are all set to be an arc shape with the first axis as the center. In this way, it is convenient for multiple flow channel openings to be conducted and matched, and it is also conducive to improving the matching accuracy.

[0061] In the specific scheme, the radial dimensions of the first flow channel opening 23 and the second flow channel opening 24 are greater than the radial dimensions of the third flow channel opening 33 and the fourth flow channel opening 34, so that the third flow channel opening 33 can completely fall within the range of the first flow channel opening 23, and the fourth flow channel opening 34 can completely fall within the range of the second flow channel opening 24, which is conducive to the fluid flowing from the movable valve component 3 to the fixed valve component 2.

[0062] It should be noted that the "radial dimension" in this article refers to the dimension in the direction close to and away from the first axis. For example, if the flow channel opening is an arc shape (strip-shaped and extending along the arc line), the radial dimension is the distance between the inner arc edge and the outer arc edge of the flow channel opening. The "corresponding central angle of a certain thing" in this article is the angle formed by the two ends of the thing in the direction around the first axis and the lines connecting the first axis, which is also equivalent to the central angle of the arc corresponding to the arc when the thing is an arc shape.

[0063] Among them, the center angle corresponding to the first flow channel opening 23 is greater than the center angle corresponding to the third flow channel opening 33, so that the third flow channel opening 33 can rotate with the valve member 3 within the range of the first flow channel opening 23, and the opening of the first valve opening formed by the first flow channel opening 23 and the third flow channel opening 33 remains unchanged. And the center angle corresponding to the second flow channel opening 24 is greater than the center angle corresponding to the fourth flow channel opening 34, so that the fourth flow channel opening 34 can rotate with the valve member 3 within the range of the second flow channel opening 24, and the opening of the second valve opening formed by the second flow channel opening 24 and the fourth flow channel opening 34 remains unchanged. In this way, in the first valve opening and the second valve opening, the opening of one can be kept unchanged, and the opening of the other can be increased or decreased, thereby improving the adjustability of the two fluid channels.

[0064] The interval area between the first flow channel opening 23 and the second flow channel opening 24 is the first interval area, and the interval area between the third flow channel opening 33 and the fourth flow channel opening 34 is the second interval area. Here, the central angle corresponding to the first interval area is greater than or equal to the central angle corresponding to the fourth flow channel opening 34. In this way, the fourth flow channel opening 34 can be placed in the first interval area between the first flow channel opening 23 and the second flow channel opening 24, thereby placing the fourth flow channel opening 34 in a closed state. At this time, the opening of the second valve opening formed by the fourth flow channel opening 34 and the second flow channel opening 24 is zero. When the rotation angle of the movable valve member 3 is within the preset range, the opening of the second valve opening can be increased from zero or gradually decreased to zero, thereby reasonably controlling the opening range of the second valve opening.

[0065] In some preferred embodiments, the center angle corresponding to the first spacing area is greater than or equal to the center angle corresponding to the second spacing area, and the center angle corresponding to the first spacing area is less than the sum of the center angle corresponding to the second spacing area and the center angle corresponding to the fourth flow channel opening 34. In the process of the movable valve member 3 rotating in the clockwise direction relative to the fixed valve member 2, when the third flow channel opening 33 just completely falls into the range of the first flow channel opening 23, the fourth flow channel opening 34 just enters the first spacing area, or has entered the first spacing area, and the fourth flow channel opening 34 has not completely left the range of the second flow channel opening 24. At this time, the movable valve member 3 continues to rotate in the clockwise direction, the third flow channel opening 33 is still within the range of the first flow channel opening 23, and the overlapping area of ​​the fourth flow channel opening 34 and the second flow channel opening 24 gradually decreases. In this way, the opening of the second valve opening can be reduced or increased while ensuring that the opening of the first valve opening remains unchanged.

[0066] like Figure 4 , 5As shown, a widening portion 331 is provided at one end of the third flow channel opening 33 away from the fourth flow channel opening 34, and the radial dimension of the widening portion 331 is greater than the radial dimension of other positions on the second flow channel opening 24, so as to widen part of the second flow channel opening 24. In this way, when the widening portion 331 enters the range of the first flow channel opening 23, the opening of the first valve opening can be quickly changed, until the widening portion 331 completely enters the range of the first flow channel opening 23, the change of the opening of the first valve opening slows down, and then the change speed of the opening of the first valve opening can be designed according to actual needs.

[0067] Among them, the center angle corresponding to the second flow channel opening 24 is less than or equal to the difference between the center angle corresponding to the third flow channel opening 33 and the fourth flow channel opening 34 and the center angle corresponding to the widening portion 331. Here, the center angle corresponding to the third flow channel opening 33 and the fourth flow channel opening 34 is the sum of the center angle corresponding to the third flow channel opening 33, the center angle corresponding to the fourth flow channel opening 34, and the center angle corresponding to the second interval area. In this way, when the fourth flow channel opening 34 is completely within the range of the second flow channel opening 24, the third flow channel opening 33 can overlap with the second flow channel opening 24. At this time, at least the widening portion 331 of the third flow channel opening 33 is in the first interval area between the first flow channel opening 23 and the second flow channel opening 24, so that the third flow channel opening 33 and the fourth flow channel opening 34 cannot be completely within the range of the second flow channel opening 24, and the maximum flow rate of the second fluid channel can be adaptively controlled according to actual needs.

[0068] In the specific scheme, the center angle corresponding to the first flow channel opening 23 is equal to the center angle corresponding to the third flow channel opening 33 and the fourth flow channel opening 34. In this way, the third flow channel opening 33 and the fourth flow channel opening 34 can be completely within the range of the second flow channel opening 24 at the same time, and then the maximum flow rate of the first fluid channel can be adaptively controlled according to actual needs. The center angle corresponding to the first spacing area is equal to the center angle corresponding to the second spacing area. In the process of the movable valve member 3 rotating in the clockwise direction relative to the fixed valve member 2, when the first spacing area and the second spacing area overlap, the third flow channel opening 33 just completely enters the range of the first flow channel opening 23, and the fourth flow channel opening 34 just leaves the range of the second flow channel opening 24. In this way, when adjusting the two fluid channels, any rotation angle of the movable valve member 3 will adjust the flow of the two fluid channels, which is conducive to improving the sensitivity of the adjustment and avoiding the redundancy of the rotation angle.

[0069] In addition, the central angle corresponding to the third flow channel opening 33 and the central angle corresponding to the fourth flow channel opening 34 may be equal to the central angle corresponding to the first interval area, so as to further improve the sensitivity of the adjustment.

[0070] The following specifically describes the process in which the movable valve member 3 rotates relative to the fixed valve member 2 in the clockwise direction according to the specific solution of the first embodiment.

[0071] The movable valve member 3 rotates to Figure 5 When the movable valve member 3 is in the position shown, the third flow channel opening 33 and the fourth flow channel opening 34 are partially within the range of the second flow channel opening 24, and the widened portion 331 of the third flow channel opening 33 is in the first spacing area. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the second fluid channel remains unchanged at first and then gradually decreases. Figure 6 When the movable valve member 3 is in the position shown in FIG. 1 , the third flow channel opening 33 is in the first interval area, and the fourth flow channel opening 34 is completely within the range of the second flow channel opening 24. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel gradually increases, and the flow rate of the second fluid channel remains unchanged. Figure 7 When the movable valve member 3 is in the position shown in FIG. 1 , the third flow channel opening 33 is completely within the range of the first flow channel opening 23, and the fourth flow channel opening 34 is completely within the range of the second flow channel opening 24. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel gradually remains unchanged, and the flow rate of the second fluid channel decreases. Figure 8 When the movable valve member 3 is in the position shown, the third flow channel opening 33 is completely within the range of the first flow channel opening 23, and the fourth flow channel opening 34 is completely within the first interval area. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel gradually increases, and the flow rate of the second fluid channel remains unchanged. Fig. 9 In the position shown, the third flow channel opening 33 and the fourth flow channel opening 34 are completely within the range of the first flow channel opening 23, and the flow rate of the first fluid channel is at a maximum value.

[0072] like Figure 11-18 As shown, in the second embodiment, the fourth flow channel opening 34 is generally arc-shaped. In addition, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 may all be generally arc-shaped. Specifically, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 are all located on the first circumference, and the circle of the first circumference is located on the first axis, that is, the first flow channel opening 23, the second flow channel opening 24, the third flow channel opening 33 and the fourth flow channel opening 34 are all set to be an arc shape with the first axis as the center. In this way, it is convenient for multiple flow channel openings to be conducted and matched, and it is also conducive to improving the matching accuracy.

[0073] The fourth flow channel 34 includes a plurality of openings, which are arranged in a direction around the first axis, and the radial dimensions of the plurality of openings are different, so that the flux of each opening when it overlaps with the second flow channel 24 is different. In the process of the movable valve member 3 rotating relative to the fixed valve member 2, the plurality of openings overlap and communicate with the second flow channel 24 in sequence, so that the opening of the second valve port formed by the fourth flow channel 34 and the second flow channel 24 increases or decreases with the rotation of the movable valve member 3. In this way, the opening size of the second valve port is adjusted by the different radial dimensions at different positions on the fourth flow channel 34, which has a simple structure and is easy to control accurately.

[0074] like Fig.12 As shown, the number of openings is set to three, including a first opening 341, a second opening 342 and a third opening 343 arranged in sequence along the direction around the first axis, the first opening 341 is close to the third flow channel opening 33, and the third opening 343 is far away from the third flow channel opening 33. When the third flow channel opening 33 is just completely within the range of the first flow channel opening 23, the opening of the first valve opening formed by the third flow channel opening 33 and the first flow channel opening 23 is the largest. At this time, the third opening 343 overlaps and communicates with the second flow channel opening 24, and the first opening 341 and the second opening 342 are in the first interval area. In this way, when the movable valve member 3 rotates relative to the fixed valve member 2 along the clockwise direction, the opening of the first valve opening remains unchanged, and the opening of the second valve opening gradually decreases, thereby realizing independent regulation of a single fluid channel.

[0075] In some preferred solutions, the central angle corresponding to any one of the first opening 341, the second opening 342 and the third opening 343 is equal to the central angle corresponding to the second flow channel opening 24, so that any one of the first opening 341, the second opening 342 and the third opening 343 can overlap and conduct with the second flow channel opening 24 alone, thereby forming three different flow control nodes, which is conducive to achieving precise control of the flow of the fluid channel. Moreover, the radial size of the third opening 343 is larger than the radial size of the second opening 342, and smaller than the radial size of the first opening 341. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow of the second fluid channel first decreases and then increases, thereby enabling adaptive and precise control of the flow of the fluid channel according to actual needs.

[0076] The following specifically describes the process in which the movable valve member 3 rotates relative to the fixed valve member 2 in the clockwise direction with respect to the specific scheme of the second embodiment.

[0077] The movable valve member 3 rotates to Fig.133, the third flow channel 33 is completely in the first spacing area, the first opening 341 of the fourth flow channel 34 is completely in the range of the second flow channel 24, and when the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel is zero and remains unchanged, and the flow rate of the second fluid channel gradually decreases. Fig.14 3, the third flow channel 33 is completely in the first spacing area, the second opening 342 of the fourth flow channel 34 is completely in the range of the second flow channel 24, and when the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel gradually increases, and the flow rate of the second fluid channel gradually increases. Fig.15 2, the third flow channel opening 33 is completely within the range of the first flow channel opening 23, and the third opening portion 343 of the fourth flow channel opening 34 is completely within the range of the second flow channel opening 24. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel remains unchanged, and the flow rate of the second fluid channel gradually decreases. Fig.16 When the movable valve member 3 is in the position shown, the third flow channel opening 33 is completely within the range of the first flow channel opening 23, and the fourth flow channel opening 34 is completely within the first interval area. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the flow rate of the first fluid channel gradually increases, and the flow rate of the second fluid channel is zero and remains unchanged. Fig.17 In the position shown, the first opening 341 of the third flow channel opening 33 and the fourth flow channel opening 34 is completely within the range of the first flow channel opening 23, and the second opening 342 and the third opening 343 of the fourth flow channel opening 34 are in the first spacing area. When the movable valve member 3 rotates clockwise relative to the fixed valve member 2, the third flow channel opening 33 leaves the range of the first flow channel opening 23, and the second opening 342 of the fourth flow channel opening 34 enters the range of the first flow channel opening 23, thereby changing the flow rate of the first fluid channel.

[0078] like Figure 4 , 12 As shown, in this solution, each fixed valve member flow channel includes a guide hole 35 and a throttling hole. The throttling hole is closer to the fixed valve member 2 relative to the guide hole 35. The guide holes 35 of multiple fixed valve member flow channels are connected as a whole and are arranged as a groove-type structure, and the groove width of the groove-type structure gradually decreases along the direction close to the groove bottom, so as to achieve the guiding effect on the fluid through the guide hole 35. The throttling holes of multiple fixed valve member flow channels are all arranged at the groove bottom of the groove structure. Specifically, the third flow channel opening 33 and the fourth flow channel opening 34 are respectively located at one end of the two throttling holes away from the guide hole 35, and the width of the throttling hole is smaller than the width of the guide hole 35, so as to achieve the throttling of the fluid through the throttling hole. In this way, through the design of the throttling hole and the guide hole 35, the circulation effect of the fluid can be improved.

[0079] like Figure 1 ,2 As shown, a drainage chamber 25 is provided between the fixed valve member 2 and the housing 1, and the drainage chamber 25 extends along the circumference of the fixed valve member 2, wherein the inner side of the drainage chamber 25 is connected to a fixed valve member flow channel, and the outer side of the drainage chamber 25 is connected to an outlet, so as to realize a one-to-one connection between a fixed valve member flow channel and an outlet. In this way, through the design of the drainage chamber 25, the fixed valve member flow channels and the outlet in different directions can be connected, which is conducive to realizing a one-to-one connection between multiple fixed valve member flow channels and multiple outlets.

[0080] In the specific scheme, two outlets are provided on the shell 1, the first outlet 12 is provided at the end of the shell 1, and the second outlet 13 is provided on the side of the shell 1, and two fixed valve flow channels are provided on the fixed valve member 2. The first fixed valve flow channel 21 runs through the fixed valve member 2 and is connected with the first outlet 12, and the second fixed valve flow channel 22 first extends from one end of the fixed valve member 2 to the middle part, and then extends from the middle part to the side of the fixed valve member 2. The drainage chamber 25 includes a drainage groove provided on the inner side of the shell 1, which extends along the circumference of the fixed valve member 2 and is connected with the second fixed valve flow channel 22. At the same time, the drainage groove is correspondingly connected with the second outlet 13, thereby realizing the connection between the second fixed valve flow channel 22 and the second outlet 13.

[0081] The valve device also includes a drive assembly 4, which is fixedly connected to the housing 1 and is transmission-connected to the movable valve member 3 via a drive shaft. For example, the drive assembly 4 includes a motor stator and a motor rotor, and the motor stator is fixedly connected to the housing 1. The motor stator is transmission-connected to the movable valve member 3 via a drive shaft. The movable valve member 3 is driven to rotate relative to the housing 1 by controlling the motor rotor to rotate relative to the motor stator.
