Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and more specifically, to a novel three-way water valve. Background Technology

[0002] With the development of new energy vehicle technology, reducing costs and improving efficiency is a key focus and a challenging issue that requires long-term attention in R&D. The three-electric system (battery, motor, and electronic control system) of new energy vehicles has consistently suffered from high costs and low efficiency. Among these systems, the vehicle's thermal management system is the most energy-intensive and costly component. The three-way water valve is a crucial component in the circulating water circuit of this system; however, current three-way water valves have complex structures and numerous internal parts, leading to high manufacturing costs, cumbersome inventory management, and complex assembly processes. Therefore, the inherent cost of the three-way water valve in the vehicle's thermal management system significantly hinders cost reduction and efficiency improvement in the design of the three-electric system for new energy vehicles.

[0003] In summary, existing three-way water valves used in vehicle thermal management systems suffer from technical problems such as complex structure and high operating costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing three-way water valves used in vehicle thermal management systems have complex structures and high operating costs.

[0005] To address the aforementioned problems, this utility model provides a novel three-way water valve, comprising a hollow cylindrical water valve housing and a valve core located within the water valve housing. The water valve housing has a cylindrical valve cavity at its center. The valve core is cylindrical, and its outer peripheral wall is fitted and sealed to the valve cavity of the water valve housing. Three valve connectors are evenly spaced at 120° intervals on the outer peripheral wall of the water valve housing. A flow channel hole is provided in the valve cavity at the position corresponding to the valve connector. Two valve holes are spaced at 120° intervals on the outer peripheral wall of the valve core, and the two valve holes communicate within the valve core. A sealing sleeve is fitted onto the outer peripheral wall of the valve core. The sealing sleeve includes two sealing ring portions located on the upper and lower sides of the valve holes, respectively, and three sealing strip portions disposed between the valve holes and oriented parallel to the axial direction of the valve core. The two ends of each sealing strip portion are integrally formed and connected to the two sealing ring portions. Both the sealing ring portions and the sealing strip portions abut against and seal against the inner peripheral wall of the water valve housing.

[0006] This utility model provides an optimized and improved three-way water valve that improves upon the traditional valve core sealing design. The valve core and valve housing are connected via a plug-in mechanism, meaning the water flow at the valve joint is switched by rotating the valve core. Therefore, the sealing structure between the valve core and the inner cavity of the valve housing is crucial. It must prevent water leakage and ensure the effective switching of the water flow at the joint. Conventional sealing designs are therefore complex, requiring numerous individual sealing units and different sealing structures for different sealing positions. Consequently, the sealing design of the water valve alone necessitates the manufacture of various components, leading to challenges in supply, storage, and... Assembly also requires specific consideration. The improved sealing design of this application achieves the leak-proof seal of the water valve by two sealing rings located on the upper and lower sides of the valve hole, while the accurate sealing between the flow channels is achieved by three circumferential sealing strips separated between the two valve holes. In order to simplify the sealing design, the two sealing rings and three sealing strips are injection molded or otherwise integrally formed, thus combining the original multiple sealing components into a single piece, which greatly saves upstream supply and storage costs, reduces assembly steps, effectively reduces the cost of the water valve device, and effectively solves the technical problems of complex structure and high operating cost of existing three-way water valves used in vehicle thermal management systems.

[0007] As a preferred embodiment, the valve core has protruding rotating shaft structures at both ends, and the bottom surface of the inner peripheral wall of the water valve housing has a raised limiting boss. A limiting hole is located at the center of the top surface of the limiting boss, and the end of the rotating shaft structure extends into the limiting hole to limit the valve core. This design optimizes the rotational fit between the valve core and the water valve housing. By limiting the rotating shaft structure coaxial with the valve core through the limiting boss and the limiting hole, the end of the rotating shaft cannot disengage from the limiting hole, ensuring stable rotation of the valve core and preventing jamming.

[0008] As a preferred embodiment, the outer peripheral wall of the valve core is provided with an annular groove and a vertical groove at positions corresponding to the sealing ring and sealing strip, respectively. The annular groove and the vertical groove are connected to each other for positioning the sealing sleeve. This design optimizes the positioning method between the sealing sleeve and the outer peripheral wall of the valve core. The grooves on the outer peripheral wall of the valve core are designed to perfectly fit the structure of the sealing sleeve, effectively positioning the sealing sleeve. Since the sealing sleeve must be pressed against the inner wall of the water valve housing, this structure can effectively prevent the sealing sleeve from shifting on the valve core surface and can also prevent misinstallation during the assembly process.

[0009] As a preferred embodiment, the top end face of the valve core is provided with a protruding limiting block, and the inner peripheral wall of the water valve housing is provided with a protruding limiting mating block at the height corresponding to the limiting block. The rotation range of the valve core within the water valve housing is limited by the abutting of the respective side end faces of the limiting block and the limiting mating block. This design optimizes the rotational fit between the valve core and the water valve housing. Since the valve core has two different switching positions, to ensure that the flow channel hole on the water valve housing is aligned with the valve hole on the valve core, the limiting block and the limiting mating block limit the rotation angle of the valve core by the abutting of their respective side end faces.

[0010] As a preferred embodiment, both the limiting block and the limiting mating block are arc-shaped protrusions with an arc angle of 120°. The abutting of their end faces ensures that the valve core's rotation range is 120°. This design further optimizes the structure of the limiting block and the limiting mating block based on the above structure, making their structures suitable for the cylindrical surfaces of the valve core and valve cavity. The 120° design ensures accurate positioning of the valve core at its rotational extreme point.

[0011] As a preferred embodiment, the inner peripheral wall of the water valve housing is provided with a stepped surface structure below the limiting mating block, and the bottom end face of the limiting mating block is integrally connected to the protruding side of the stepped surface structure. This design further optimizes the inner peripheral wall structure of the water valve housing at the location of the limiting mating block by providing a circumferential stepped surface structure. The outer side of the stepped surface has a larger diameter, and the inner side has a smaller diameter. This stepped surface structure can limit the bottom side of the limiting block on the valve core, effectively limiting the axial position of the valve core, ensuring accurate height of the valve core within the valve cavity, and guaranteeing the effective operation of the valve.

[0012] As a preferred embodiment, the diameter of the valve orifice is consistent with the diameter of the flow channel orifice in the valve cavity. This reduces the diameter of the original mating position, lowers the driving torque required for valve core rotation, and reduces the operating energy consumption of the water valve.

[0013] As a preferred embodiment, the rotating shaft structure is fitted with a sealing gasket and a cover plate. The cover plate is fastened and fixed to the water valve housing, and the sides of the sealing gasket and the cover plate abut against each other. This design optimizes the fit between the valve core end and the valve cavity opening end, and the combination of the cover plate and the sealing gasket effectively prevents water leakage.

[0014] As a preferred embodiment, the end of the rotating shaft structure located on the outer side of the cover plate is provided with a protruding circumferential positioning structure for connecting to an external drive mechanism via the circumferential positioning structure. The circumferential positioning structure at the shaft end can be a spline or a flat rectangular structure, facilitating the transmission of rotation through this structure.

Figure 1 A schematic diagram of the external overall structure of a novel three-way water valve provided by this utility model; Figure 2 for Figure 1 Schematic diagram of the internal structure of the new type of three-way water valve; Figure 3 for Figure 1 A schematic diagram of the valve core structure of the new type of three-way water valve; Figure 4 for Figure 3 A partial structural diagram of the valve core of the new type of three-way water valve; Figure 5 for Figure 3 A schematic diagram of the sealing sleeve structure of the valve core of the new type of three-way water valve; Figure 6 for Figure 1 A schematic diagram of the internal structure of the housing of the new type of three-way water valve.

[0020] This embodiment provides a novel three-way water valve, comprising a hollow cylindrical water valve housing 1 and a valve core 2 located within the water valve housing 1. The water valve housing 1 has a cylindrical valve cavity at its center. The valve core 2 is cylindrical, and its outer peripheral wall is fitted and sealed to the valve cavity of the water valve housing 1. Three valve connectors 5 are evenly arranged at 120° intervals on the outer peripheral wall of the water valve housing 1. The valve cavity has flow channels at positions corresponding to the valve connectors 5. Two flow channels are arranged at 120° intervals on the outer peripheral wall of the valve core 2. There are two valve holes 4, which are connected inside the valve core 2. A sealing sleeve 3 is fitted on the outer peripheral wall of the valve core 2. The sealing sleeve 3 includes two sealing ring parts 3-1 located on the upper and lower sides of the valve hole 4, and three sealing strip parts 3-2 disposed between the valve holes 4 and parallel to the axial direction of the valve core 2. The two ends of the sealing strip parts 3-2 are integrally formed and connected to the two sealing ring parts 3-1. The sealing ring parts 3-1 and the sealing strip parts 3-2 abut against the inner peripheral wall of the water valve housing 1 for sealing.

[0021] This utility model provides an optimized and improved three-way water valve that improves upon the traditional valve core 2 sealing design. The valve core 2 and the water valve housing 1 are connected via a plug-in mechanism, meaning the water flow mode of the valve connector is switched by rotating the valve core 2. Therefore, the sealing structure between the valve core 2 and the inner cavity of the valve housing is crucial. It must ensure that the valve does not leak water and that the water flow switching at the connector is effective. Consequently, conventional sealing designs are complex, requiring numerous individual sealing units and different sealing structures for different sealing positions. Therefore, the sealing design of the water valve alone necessitates the manufacture of various different parts, which also necessitates improvements in supply, storage, and assembly. The sealing design of this application is targeted, and the improved sealing design of this application achieves the sealing of the water valve to prevent external leakage by two sealing rings 3-1 located on the upper and lower sides of the valve hole 4, while the sealing of accurate switching between the flow channels is achieved by three sealing strips 3-2 circumferentially separated between the two valve holes 4. In order to simplify the sealing design, the two sealing rings 3-1 and the three sealing strips 3-2 are integrally molded by injection molding or other methods. In this way, the original multiple sealing components are combined into a single piece, which greatly saves the upstream supply and storage costs, reduces assembly steps, effectively reduces the cost of the water valve device, and effectively solves the technical problems of complex structure and high operating cost of the existing three-way water valve used in vehicle thermal management systems.

[0022] In the technical solution provided in this embodiment, the valve core 2 has protruding rotating shaft structures 6 at both ends, and the bottom surface of the inner peripheral wall of the water valve housing 1 has a raised limiting boss 14. The center of the top surface of the limiting boss 14 has a limiting hole, and the end of the rotating shaft structure 6 extends into the limiting hole to limit the valve core 2. This design optimizes the rotational fit between the valve core 2 and the water valve housing 1. By limiting the rotating shaft structure 6, which is coaxial with the valve core 2, through the limiting boss 14 and the limiting hole, the rotating shaft end cannot rotate away from the limiting hole, ensuring stable rotation of the valve core 2 and preventing jamming.

[0023] In the technical solution provided in this embodiment, the outer peripheral wall of the valve core 2 is provided with an annular groove 11 and a vertical groove 12 at positions corresponding to the sealing ring portion 3-1 and the sealing strip portion 3-2, respectively. The annular groove 11 and the vertical groove 12 are connected and used to sink and position the sealing sleeve 3. This design optimizes the positioning method between the sealing sleeve 3 and the outer peripheral wall of the valve core 2. The outer peripheral wall of the valve core 2 is designed with grooves that are fully adapted to the structure of the sealing sleeve 3. The sealing sleeve 3 is effectively positioned by the grooves. Since the sealing sleeve 3 needs to be pressed against the inner side wall of the water valve housing 1, this structure can effectively prevent the sealing sleeve 3 from deviating on the surface of the valve core 2 and can also prevent misinstallation during the assembly of the sealing sleeve 3.

[0024] In the technical solution provided in this embodiment, a protruding limiting block 9 is provided on the top end face of the valve core 2, and a protruding limiting mating block 10 is provided on the inner peripheral wall of the water valve housing 1 at the height corresponding to the limiting block 9. The rotation range of the valve core 2 within the water valve housing is limited by the abutting of the respective side end faces of the limiting block 9 and the limiting mating block 10. This design optimizes the rotational fit between the valve core 2 and the water valve housing 1. Since the valve core 2 has two different switching positions, to ensure that the flow channel hole on the water valve housing 1 is aligned with the valve hole 4 on the valve core 2, the limiting block 9 and the limiting mating block 10 limit the rotation angle of the valve core 2 by the abutting of their side end faces.

[0025] In the technical solution provided in this embodiment, both the limiting block 9 and the limiting mating block 10 are arc-shaped protrusions with an arc angle of 120°. The abutting of their end faces ensures that the rotation range of the valve core 2 is 120°. This design further optimizes the structure of the limiting block 9 and the limiting mating block 10 based on the above structure, making their structures suitable for the cylindrical surfaces of the valve core 2 and the valve cavity. The 120° design ensures accurate positioning of the valve core 2 at its rotational extreme point.

[0026] In the technical solution provided in this embodiment, the inner peripheral wall of the water valve housing 1 is provided with a stepped surface structure 13 below the limiting mating block 10, and the bottom end face of the limiting mating block 10 is integrally connected to the protruding side of the stepped surface structure 13. This design further optimizes the inner peripheral wall structure of the water valve housing 1 at the position of the limiting mating block 10 by setting a circumferential stepped surface structure 13. The outer side of the stepped surface has a larger diameter, and the inner side has a smaller diameter. The stepped surface structure can limit the bottom side of the limiting block 9 on the valve core 2, effectively limiting the axial position of the valve core 2, ensuring the accurate height of the valve core 2 in the valve cavity, and guaranteeing the effectiveness of valve operation.

[0027] In the technical solution provided in this embodiment, the diameter of the valve hole 4 is consistent with the diameter of the flow channel hole in the valve cavity. This reduces the diameter of the original mating position, lowers the driving torque required for the valve core 2 to rotate, and reduces the operating energy consumption of the water valve.

[0028] In the technical solution provided in this embodiment, the cover plate 7 is fastened and fixed to the water valve housing 1, and the sealing gasket 8 abuts against the side of the cover plate 7. This design optimizes the fit between the end of the valve core 2 and the opening end of the valve cavity, and the design of the cover plate 7 and the sealing gasket 8 can effectively prevent water leakage.

[0029] In the technical solution provided in this embodiment, the end of the rotating shaft structure 6 located on the outer side of the cover plate 7 is provided with a protruding circumferential positioning structure for connecting to an external drive mechanism through the circumferential positioning structure. The circumferential positioning structure at the shaft end can be a spline or a flat rectangular structure, facilitating the transmission of rotation through this structure.

[0030] Although the embodiments of this utility model have been disclosed above, the scope of protection of this utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model, and all such changes and modifications will fall within the protection scope of this utility model.
