Description

Technical Field

[0001] The utility model relates to the field of intelligent thermal management systems for new energy vehicles, and in particular to a multi-way electronic water valve with a shared shell and proportional control. Background Art

[0002] At present, the thermal management system of new energy vehicles is becoming increasingly complex. The temperature control requirements between different working circuits such as electric drive circuit / battery circuit / motor circuit are different, and the coolant flow rate flowing to each working system is also different. From the perspective of technical advantages and costs, most new energy vehicle manufacturers use thermal management integrated modules to adjust the flow and temperature of each circuit. Due to the different cooling system architectures of various new energy vehicle manufacturers, the requirements for the number of integrated channels of water valves in the thermal management integrated module are different. For example, small integrated modules often use three-way electronic water valves or four-way electronic water valves, and large integrated modules often use five-way / eight-way electronic water valves. The water valve structures are also various, mainly customized development, with a long development cycle, and the platform effect is not satisfactory, which brings high R&D / manufacturing costs. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and to provide a multi-way electronic water valve with a shared shell and proportional control. By adopting this solution, a central drainage port is provided at the bottom of the valve, and a number of evenly distributed flow channel ports are provided on the side wall of the valve to form a platform shell, thereby realizing a shared water valve shell for the multi-way water valves, which is beneficial to the platform development of the water valve, shortens the development cycle, and reduces the complexity.

[0004] The utility model is achieved through the following technical solutions:

[0005] A multi-way electronic water valve with a shared housing and proportional control, comprising:

[0006] A valve housing, wherein a plurality of uniformly distributed flow openings are uniformly distributed on the circumferential side wall of the valve cavity of the valve housing, and the plurality of uniformly distributed flow openings are circumferentially arranged along the axis of the valve cavity; a central drainage port is coaxially opened at the center of the bottom of the valve cavity of the valve housing;

[0007] A valve core is coaxially rotatably disposed in the valve cavity and is capable of rotating about its own axis; the valve core is sealed to the inner wall of the valve housing via an inner sealing gasket, and the inner sealing gasket has openings at positions corresponding to the uniformly distributed flow channel openings;

[0008] The part of the valve core located in the valve cavity is provided with two first flow channels and a second flow channel that are not connected to each other. During the rotation of the valve core, the first flow channel can be connected to at least one of the uniformly distributed flow channel openings, and the second flow channel can be connected to at least one of the remaining uniformly distributed flow channel openings.

[0009] Compared to existing technologies, which feature a wide variety of water valve structures, primarily custom development, long development cycles, and unsatisfactory platformization, resulting in high R&D and manufacturing costs, this utility model provides a multi-way electronic water valve with a shared housing and proportional control. This solution utilizes a central drainage port at the bottom of the valve housing and several evenly distributed flow openings on the sidewalls to form a platform housing. This allows for a shared housing for multiple valves, facilitating platform-based water valve development, shortening development cycles, and reducing complexity. This design is primarily used in electronic water valves for thermal management integrated modules in new energy vehicles.

[0010] The specific scheme includes a valve shell, a central drainage port is coaxially opened at the center of the bottom of the valve cavity of the valve shell, and several evenly distributed flow openings are opened on the circumferential side wall of the valve cavity. In this way, an integrated multi-way water valve can be formed through the central drainage port and several evenly distributed flow openings, realizing a multi-channel shared water valve shell, which is conducive to the platform development of water valves and shortens the development cycle. For example, if 4 evenly distributed flow openings are set, a four-way valve can be formed by closing the central drainage port, and a five-way valve can be formed by not closing the central drainage port. In addition, a valve core is provided, which extends into the valve cavity and can rotate coaxially within the valve cavity. Two mutually unconnected first and second flow channels are provided on both sides of the bottom of the valve core. The first and second flow channels can realize the communication function between the valve core and the multiple uniformly distributed flow channel openings around the valve housing during the rotation of the valve core, realize the communication between the multiple uniformly distributed flow channel openings, and also realize the proportional adjustment function of the water valve, realizing different flow rates in the same flow channel; an inner sealing gasket is provided between the side of the valve core and the inner wall of the valve cavity, and the inner sealing gasket has openings at the corresponding uniformly distributed flow channel openings. In this way, during the rotation of the valve core, a rotary sealing function can be realized, and it is ensured that the flow channel can realize liquid circulation with the corresponding uniformly distributed flow channel openings. Among them, the uniformly distributed flow channel openings are preferably four and are symmetrically arranged around the axis of the valve cavity.

[0011] In order to further realize an integrated multi-way water valve, the outer side wall of the valve housing is circumferentially provided with a plurality of integrally formed pipes, and each of the pipes is connected to a corresponding one of the uniformly distributed flow channel openings.

[0012] To facilitate rotation of the valve core, a coaxial shaft is provided at each end of the valve core. The lower shaft is rotatably connected to the bottom of the valve cavity, while the upper shaft extends out of the valve housing and connects to an external drive mechanism. A shaft seal is provided within the lower shaft and the center hole of the end cap, providing a dynamic seal between the valve core and the end cap.

[0013] To seal the top of the valve housing, an end cap is installed. The center of the end cap contains a hole for the valve core's upper rotating shaft to pass through. The valve cap is mounted on the top of the valve housing and connected to it by welding or screws, providing a clearance fit with the valve core. The valve core's upper rotating shaft can be connected to an external drive device through the hole, and the top of the end cap often has mounting holes for external devices.

[0014] To achieve sealing at various flow openings, a sealing ring mounting groove is provided on the bottom of the valve chamber and the mounting surface for the counterpart. A sealing ring is positioned within the groove. The sealing ring is located on the bottom of the water valve housing and the mounting surface for the counterpart. Once installed, the sealing ring achieves sealing at various flow openings while preventing leakage between the mounting surface of the electronic water valve and the counterpart.

[0015] As a further structure of a shared water valve housing, the first flow channel is connected to the central drainage port. During the rotation of the valve core, the first flow channel can communicate with the central drainage port and at least one of the uniformly distributed flow ports, and the second flow channel can communicate with at least two of the remaining uniformly distributed flow ports. In this solution, a central drainage port is added to the bottom of the valve housing to increase the number of channels. If there are four uniformly distributed flow ports, the water valve with the added central drainage port becomes a five-way water valve, forming a shared water valve housing for the five-way water valve.

[0016] As a specific structure of the valve core, the rotating shaft at the lower end of the valve core includes a hollow arc-shaped plate segment, and the arc-shaped plate segment and the central drainage port are coaxial; the first flow channel and the second flow channel are respectively located on both sides of the arc-shaped plate segment;

[0017] Both ends of the arc-shaped plate segment are provided with movable sealing ends; during the rotation of the valve core, the movable sealing ends are used to close or open one of the uniformly distributed flow channel openings. In this solution, the inner diameter of the arc-shaped plate segment is not less than the diameter of the central drainage port, and is coaxially arranged; thus, the inner concave side of the arc-shaped plate is the first flow channel, which can always be in a conductive state with the central drainage hole at the bottom of the valve housing regardless of the angle to which the valve core rotates, and is used to achieve communication with the central drainage port and one or two other uniformly distributed flow channel openings through the first flow channel; the outer convex side of the arc-shaped plate is the second flow channel, which has a larger circumferential length and can be connected with at least two of the remaining uniformly distributed flow channel openings.

[0018] In order to improve the sealing effect, in the circumferential direction of the axis of the central drainage port, the movable sealing end is an arc surface that is adapted to the inner wall of the valve housing.

[0019] As a redundant solution, in the circumferential direction of the central drainage port axis, the arc of the second flow channel is ≥180°.

[0020] As another specific structure of the valve core, the bottom of the valve core blocks the central drainage port; the portion of the valve core located in the valve cavity includes a linear plate segment, which is arranged radially along the valve cavity; the first flow channel and the second flow channel are respectively located on both sides of the linear plate segment, and both sides of the linear plate segment have an arc surface with a central concave portion, and the linear plate segment is symmetrical along the axis of the valve cavity;

[0021] Each end of the linear plate segment is provided with a movable sealing end; during rotation of the valve core, the movable sealing end is used to close or open one of the uniformly distributed flow openings. In this embodiment, if there are four uniformly distributed flow openings and the central drainage opening is blocked, a four-way water valve with a common valve housing is formed. The valve core drives the linear plate segment to rotate, thereby connecting the first flow channel with two of the uniformly distributed flow openings, and connecting the second flow channel with the other two uniformly distributed flow openings, thereby achieving flow regulation.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] 1. The utility model provides a multi-way electronic water valve with a shared shell and proportional control. By adopting this solution, a central drainage port is set at the bottom of the valve and four evenly distributed flow channel ports are set on the side wall of the valve to form a platform shell, so that the four-way water valves share the same water valve shell, which is beneficial to the platform development of water valves, shortens the development cycle and reduces the complexity.

[0024] 2. The utility model provides a multi-way electronic water valve with a shared shell and proportional control. By adopting this solution, a central drainage port is added to the bottom of the valve shell, and four evenly distributed flow channel ports are set on the side wall of the valve to form a platform shell, so that the five-way water valves can share the same water valve shell, which is beneficial to the platform development of water valves, shortens the development cycle, and reduces the complexity.

[0025] 3. The utility model provides a multi-way electronic water valve with a shared shell and proportional control. By adopting this solution, it is easy to realize the linear proportional adjustment function of the water valve flow port, reduce the complexity of valve core injection molding, and improve injection molding reliability; it can also reduce the overall size of the water valve, reduce material consumption, and facilitate product miniaturization and reduce product unit cost.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0039] Example 1:

[0040] This embodiment 1 provides a multi-way electronic water valve with a shared housing and proportional control, such as Figures 1-9 Shown, including:

[0041] A valve housing 1, wherein a plurality of uniformly distributed flow openings 102 are uniformly distributed on the circumferential side wall of the valve cavity of the valve housing 1, and the plurality of uniformly distributed flow openings 102 are circumferentially arranged along the axis of the valve cavity; a central drainage port 101 is coaxially opened at the center of the bottom of the valve cavity of the valve housing 1;

[0042] The valve core 2 is coaxially rotatably disposed in the valve cavity and can rotate around its own axis; the valve core 2 is sealed to the inner wall of the valve housing 1 via an inner sealing gasket 3, and the inner sealing gasket 3 has openings at positions corresponding to the uniformly distributed flow channel openings 102;

[0043] The part of the valve core 2 located in the valve cavity is provided with two first flow channels 201 and second flow channels 202 which are not connected to each other. During the rotation of the valve core 2, the first flow channel 201 can be connected with at least one of the uniformly distributed flow channel openings 102, and the second flow channel 202 can be connected with at least one of the remaining uniformly distributed flow channel openings 102.

[0044] Compared to existing technologies, which feature a wide variety of water valve structures, primarily custom development, long development cycles, and unsatisfactory platformization, resulting in high R&D and manufacturing costs, the present invention provides a multi-way electronic water valve with a shared housing and proportional control. This solution utilizes a central drainage port 101 at the bottom of the valve housing 1 and several evenly distributed flow openings 102 on the sidewalls of the valve housing 1 to form a platform-like housing. This allows multiple water valves to share a common valve housing 1, facilitating platform-based water valve development, shortening development cycles, and reducing complexity. This design is primarily used in electronic water valves for thermal management integrated modules in new energy vehicles.

[0045] In the specific scheme, it includes a valve shell 1, a central drainage port 101 is coaxially opened at the center of the bottom of the valve cavity of the valve shell 1, and a number of evenly distributed flow channel ports 102 are opened on the circumferential side wall of the valve cavity. In this way, an integrated multi-way water valve can be formed by the central drainage port 101 and the several evenly distributed flow channel ports 102, realizing a multi-channel shared water valve shell 1, which is conducive to the platform development of the water valve and shortens the development cycle. For example, if 4 evenly distributed flow channel ports 102 are set, a four-way valve can be formed by closing the central drainage port 101, and a five-way valve can be formed by not closing the central drainage port 101. In addition, a valve core 2 is provided, which extends into the valve cavity and can rotate coaxially in the valve cavity. Two mutually unconnected first flow channels 201 and second flow channels 202 are provided on both sides of the bottom of the valve core 2. The first flow channel 201 and the second flow channel 202 can realize the communication function between the valve core 2 and the valve housing 1 during the rotation process, realize the communication between the multiple uniformly distributed flow channels 102, and also realize the proportional adjustment function of the water valve, realizing different flow rates in the same flow channel; an inner sealing gasket 3 is provided between the side of the valve core 2 and the inner wall of the valve cavity, and the inner sealing gasket 3 has openings at the positions corresponding to the uniformly distributed flow channels 102. In this way, during the rotation process of the valve core 2, a rotary sealing function can be realized, and it is ensured that the flow channel can realize liquid circulation with the corresponding uniformly distributed flow channels 102. Among them, the uniformly distributed flow channels 102 are preferably four and symmetrically arranged around the axis of the valve cavity.

[0046] In order to further realize an integrated multi-way water valve, the outer side wall of the valve housing 1 is circumferentially provided with a plurality of integrally formed pipes, each of which is connected to a corresponding uniformly distributed flow channel opening 102 .

[0047] To facilitate the rotation of the valve core 2, a coaxial rotation shaft is provided at each end of the valve core 2. The lower end of the valve core 2 is rotatably connected to the bottom of the valve cavity, while the upper end of the valve core 2 extends out of the valve housing 1 and is connected to an external drive mechanism. A shaft seal is provided within the lower end of the valve core 2 and the center hole of the end cap 4 to achieve a dynamic sealing function between the valve core 2 and the end cap 4.

[0048] To seal the top of the valve housing 1, an end cap 4 is installed. A hole is defined in the center of the end cap 4, through which the upper rotating shaft of the valve core 2 passes. The valve cap is mounted on the top of the valve housing 1 and connected to the valve housing 1 by welding or screws, providing a clearance fit with the valve core 2. The upper rotating shaft of the valve core 2 can be connected to an external drive device through the hole. The top of the end cap 4 often includes mounting holes for external mechanisms.

[0049] To achieve sealing at various flow passages, a sealing ring mounting groove 103 is provided on the bottom of the valve chamber and the mounting surface for the counterpart. A sealing ring is positioned within this groove. The sealing ring is positioned at the bottom of the water valve housing 1 and the mounting surface for the counterpart. This groove 103 ensures sealing at various flow passages while preventing leakage between the mounting surface of the electronic water valve and the counterpart.

[0050] Example 2:

[0051] This embodiment 2 is further optimized on the basis of embodiment 1, such as Figure 2-Figure 8 As shown, a valve body structure with an additional central drainage port 101 is provided.

[0052] As a further structure of the shared water valve housing 1, the first flow channel 201 is connected to the central drainage port 101. During the rotation of the valve core 2, the first flow channel 201 can be respectively connected to the central drainage port 101 and at least one of the uniformly distributed flow ports 102, and the second flow channel 202 can be connected to at least two of the remaining uniformly distributed flow ports 102. In this solution, by adding a central drainage port 101 to the bottom of the valve housing 1 to increase the channel, if there are four uniformly distributed flow ports 102, the water valve with the added central drainage port 101 becomes a five-way water valve, thereby forming a five-way water valve shared water valve housing 1.

[0053] As a specific structure of the valve core 2, the rotating shaft at the lower end of the valve core 2 includes a hollow arc-shaped plate segment, and the arc-shaped plate segment and the central drainage port 101 are coaxial; the first flow channel 201 and the second flow channel 202 are respectively located on both sides of the arc-shaped plate segment;

[0054] Both ends of the arc-shaped plate segment are provided with movable sealing ends; during the rotation of the valve core 2, the movable sealing ends are used to close or open one of the uniformly distributed flow channel openings 102. In this solution, the inner diameter of the arc-shaped plate segment is not less than the diameter of the central drainage port 101, and is coaxially arranged; in this way, the inner concave side of the arc-shaped plate is the first flow channel 201, and no matter to which angle the valve core 2 rotates, the first flow channel 201 can always be in a conductive state with the central drainage hole at the bottom of the valve housing 1, and the first flow channel 201 is used to achieve communication with the central drainage port 101 and another or two uniformly distributed flow channel openings 102; the outer convex side of the arc-shaped plate is the second flow channel 202, which has a larger circumferential length and can be connected with at least two of the remaining uniformly distributed flow channel openings 102.

[0055] In order to improve the sealing effect, in the circumferential direction of the axis of the central drainage port 101, the movable sealing end is an arc surface adapted to the inner wall of the valve housing 1.

[0056] As a redundant solution, in the circumferential direction of the axis of the central drainage port 101 , the arc of the second flow channel 202 is ≥180°.

[0057] Specific working principle:

[0058] like Figure 2-Figure 8 As shown, a five-way water valve is provided, with four evenly distributed flow channels 102 symmetrically along the valve cavity axis. The first flow channel 201 is always connected to the central drainage port 101. Here, the four evenly distributed flow channels 102 are divided into a first evenly distributed flow channel 1021, a second evenly distributed flow channel 1022, a third evenly distributed flow channel 1023 and a fourth evenly distributed flow channel 1024. By rotating the valve core 2, the flow rate can be adjusted and turned on and off. Figure 6 As shown, when the valve core 2 rotates to this state, the first flow channel 201 is connected to the central drainage port 101 and the fourth uniformly distributed flow channel port 1024 respectively, and the second flow channel 202 is connected to the first uniformly distributed flow channel port 1021, the second uniformly distributed flow channel port 1022 and the third uniformly distributed flow channel port 1023. At this time, the second uniformly distributed flow channel port 1022 serves as a confluence port, and the first uniformly distributed flow channel port 1021 and the third uniformly distributed flow channel port 1023 serve as flow distribution ports. As the valve core 2 rotates, the flow distribution of the first uniformly distributed flow channel port 1021 and the third uniformly distributed flow channel port 1023 is realized, and in the process of implementing proportional distribution, the fourth uniformly distributed flow channel port 1024 always remains connected to the central drainage port 101.

[0059] like Figure 7 As shown, when the valve core 2 rotates to this state, the first flow channel 201 is connected to the central drainage port 101 and the fourth uniformly distributed flow channel port 1024 respectively, while the third uniformly distributed flow channel port 1023 is disconnected, and the second flow channel 202 is connected to the first uniformly distributed flow channel port 1021 and the second uniformly distributed flow channel port 1022.

[0060] Example 3:

[0061] This embodiment 3 is further defined on the basis of embodiment 1, as follows: Figure 9 As shown, another valve body structure is provided.

[0062] The bottom of the valve core 2 blocks the central drainage port 101; the portion of the valve core 2 located within the valve cavity includes a linear plate segment, which is radially arranged along the valve cavity; the first flow channel 201 and the second flow channel 202 are respectively located on both sides of the linear plate segment, and both sides of the linear plate segment are arc-shaped with a concave center, and the linear plate segment is symmetrical along the axis of the valve cavity;

[0063] Each end of the linear plate segment is provided with a movable sealing end; during the rotation of the valve core 2, the movable sealing end is used to close or open one of the uniformly distributed flow openings 102. In this embodiment, if there are four uniformly distributed flow openings 102, a four-way water valve with a common water valve housing 1 is formed. The valve core 2 drives the linear plate segment to rotate, thereby connecting the first flow channel 201 with two of the uniformly distributed flow openings 102, and connecting the second flow channel 202 with the other two uniformly distributed flow openings 102, thereby achieving flow regulation.

[0064] Specific working principle:

[0065] like Figure 9 As shown, a four-way water valve is provided, with four evenly distributed flow channels 102 symmetrically along the valve cavity axis, and the bottom of the valve core 2 blocks the central drainage port 101. Here, the four evenly distributed flow channels 102 are divided into a first evenly distributed flow channel 1021, a second evenly distributed flow channel 1022, a third evenly distributed flow channel 1023 and a fourth evenly distributed flow channel 1024; by rotating the valve core 2, the flow rate can be adjusted and turned on and off. Figure 9 As shown, when the valve core 2 rotates to this state, the first flow channel 201 is connected with the third evenly distributed flow channel opening 1023 and the fourth evenly distributed flow channel opening 1024, and the second flow channel 202 is connected with the first evenly distributed flow channel opening 1021 and the second evenly distributed flow channel opening 1022. In this way, as the valve core 2 rotates, the flow distribution of the first evenly distributed flow channel opening 1021 and the second evenly distributed flow channel opening 1022, as well as the flow distribution of the third evenly distributed flow channel opening 1023 and the fourth evenly distributed flow channel opening 1024 can be achieved.

[0066] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
