Abstract
Description
Technical Field
[0001] This utility model relates to the field of control valve technology, specifically a control valve assembly for a thermal management system of new energy vehicles. Background Technology
[0002] With the rapid development of the new energy vehicle industry, thermal management systems have become a key technology for ensuring vehicle safety and performance. As the core component for flow control in thermal management systems, the performance of control valve components directly determines the system's operating efficiency and reliability.
[0003] Currently, thermal management control valves for new energy vehicles on the market generally have some shortcomings. They have complex structural designs and are difficult to disassemble and maintain. Traditional valve components often adopt an integrated or multi-part nested structure. During maintenance, a large number of parts need to be disassembled with the help of professional tools, resulting in maintenance time of up to several hours. This not only increases after-sales costs but also significantly prolongs vehicle downtime and affects user experience. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a control valve assembly for a thermal management system of a new energy vehicle, comprising: a valve shell structure 1, wherein an inlet pipe 2, an outlet pipe 3, and a valve core structure 4 are slidably connected to the inner wall of the valve shell structure 1; the valve shell structure 1 includes a first half-shell 11, wherein a second half-shell 12 is fixedly connected to the outer wall of the first half-shell 11 by bolts, and sealing plates 13 are fixedly connected to the outer walls of both the first half-shell 11 and the second half-shell 12; ball grooves 14 are provided on the inner walls of both the first half-shell 11 and the second half-shell 12; outlet ports 15 and inlet ports 16 are provided on the outer walls of both the sides of the first half-shell 11 and the second half-shell 12; and drive grooves 17 are provided on the outer walls of the tops of both the first half-shell 11 and the second half-shell 12.
[0026] The inner wall of the discharge port 15 is slidably connected to the outer wall of the discharge pipe 3. The discharge pipe 3 is slidably locked by the discharge ports 15 on the first half shell 11 and the second half shell 12. The inner wall of the feed port 16 is slidably connected to the outer wall of the feed pipe 2. The feed pipe 2 is slidably locked by the feed ports 16 on the first half shell 11 and the second half shell 12. The sealing plates 13 on the first half shell 11 and the second half shell 12 are pressed and contacted with each other to form a planar seal.
[0027] The outer wall of the feed pipe 2 is fixedly connected with a first sealing ring 21, and the outer wall of the discharge pipe 3 is fixedly connected with a second sealing ring 31.
[0028] The inner wall of the feed port 16 slides in contact with the outer wall of the first sealing ring 21, and the inner wall of the discharge port 15 slides in contact with the outer wall of the second sealing ring 31 to prevent fluid from leaking from the pipeline interface.
[0029] The valve core structure 4 includes a ball valve core 41, a sealing sleeve 42 is fixedly connected to the outer wall of the ball valve core 41, a drive shaft 43 is fixedly connected to the outer wall of the top of the ball valve core 41, a sealing gasket 44 is fixedly connected to the outer wall of the drive shaft 43, and a servo motor 45 is rotatably connected to the outer wall of the top of the drive shaft 43.
[0030] The outer wall of the bottom of the servo motor 45 is fixedly connected to the outer wall of the top of the first half shell 11 and the second half shell 12 by bolts. The outer wall of the drive shaft 43 is slidably connected to the inner wall of the drive groove 17. The outer wall of the sealing gasket 44 is in slidable contact with the inner wall of the drive groove 17 to prevent fluid from leaking to the outside from the protruding end of the drive shaft 43. The outer wall of the sealing sleeve 42 is slidably connected to the inner wall of the ball groove 14.
[0031] In use, the valve housing structure 1 combines the valve core structure 4, the feed pipe 2 and the discharge pipe 3 inside it to form the entire valve body;
[0032] The ball valve core 41 is a hollow ball with a through flow channel inside. The outer wall is covered with a sealing sleeve 42. When the servo motor 45 starts, it drives the drive shaft 43 to rotate. Since the drive shaft 43 is rigidly connected to the ball valve core 41, the ball valve core 41 rotates synchronously with the drive shaft 43. The servo motor 45 has a built-in Hall sensor to provide real-time feedback on the rotation angle of the drive shaft 43, realizing closed-loop control. When the ball valve core 41 rotates to a specific angle, its internal flow channel is aligned with the feed pipe 2 and the discharge pipe 3 to form a fluid passage. When it rotates to other angles, the sealing sleeve 42 on the outer wall of the ball valve core 41 blocks the feed port 16 or the discharge port 15, cuts off the fluid passage, and realizes the valve closing function.
[0033] When disassembly and maintenance are required, unscrew the fixing bolts at the bottom of the servo motor 45 to release the servo motor 45 from the first half-shell 11 and the second half-shell 12. Then, loosen the connecting bolts between the first half-shell 11 and the second half-shell 12 in a diagonal sequence to release the connection between the first half-shell 11 and the second half-shell 12. Then, slide the ball valve core 41 out of the ball groove 14. The discharge pipe 3 drives the second sealing ring 31 to slide out of the inner wall of the discharge port 15. The feed pipe 2 drives the first sealing ring 21 to slide out of the inner wall of the feed port 16. This completes the disassembly of the valve body structure 1. The reverse is also true.
[0034] The first half-shell 11 and the second half-shell 12 are fastened by bolts. The middle sealing plate 13 is squeezed and deformed to form a planar seal. The first sealing ring 21 on the outer wall of the feed pipe 2 is interference-fitted with the inner wall of the feed interface 16. The second sealing ring 31 on the discharge pipe 3 is interference-fitted with the inner wall of the discharge interface 15 to prevent fluid from leaking from the pipe interface. The sealing gasket 44 on the drive shaft 43 slides in contact with the inner wall of the drive groove 17 to prevent fluid from leaking to the outside from the protruding end of the drive shaft 43.
