Description

Technical Field

[0001] The utility model relates to the technical field of electronic water valves, in particular to a seven-way electronic water valve. Background Art

[0002] With the rapid development of the new energy vehicle industry in recent years, thermal management systems have become increasingly integrated and intelligent. These systems are complex, with different operating systems requiring different temperature control requirements, resulting in varying coolant flow rates. Consequently, thermal management systems in traditional vehicles are also being optimized, with some models now using electronic water valves instead of traditional thermostats for coolant regulation. For example, prior art publication CN211764806U proposes a thermal management system for new energy vehicles. One end of the evaporator is connected to one end of the compressor via tee A. The other end of the compressor is connected to one end of a check valve A. The other end of the check valve A is connected to one end of the condenser via tee B. The other end of the condenser is connected to a four-way valve and, through an expansion valve, to the evaporator, forming a circuit. One end of an electronic valve A is connected to tee A via tee C. The other end of the electronic valve A is connected to one end of a battery cooling plate. The other end of the battery cooling plate is connected to an air pump via tee D. One end of an electronic valve B is connected to tee A via tee C. The other end of the electronic valve B is connected to one end of a motor. The other end of the motor is connected to the air pump via tee D. The end of the air pump, away from tee D, is connected to tee B via check valve B. The electronic water valve is a new type of coolant flow control valve in new energy vehicle thermal management systems. Its function and operating principle are similar to those of thermostats in traditional fuel vehicles. Its main function is to adaptively adjust the flow rate of coolant in each pipeline according to the temperature changes of different working parts, ensuring that the battery, motor, etc. are in the optimal working temperature environment, so as to achieve the purpose of energy conservation, emission reduction and improved energy utilization.

[0003] However, current thermal management systems rely on multiple electronic valves to control each medium flow channel, maintaining either a series or parallel connection. This allows the thermal management system to implement separate flow loops or adjust them to form a single flow loop. Traditional thermal management systems involve multiple electronic valves, resulting in complex and costly structures and complicated medium flow channels. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a seven-way electronic water valve that can quickly adjust the opening, change the flow channel, and realize proportional switching of the flow channel to ensure that each thermal management system is in the best working state.

[0005] A seven-way electronic water valve of the present utility model comprises an actuator and a valve body half assembly. The actuator is installed above the valve body half assembly. The valve body half assembly consists of a valve cover, a sealing ring, a valve core, a gasket, and a valve body. The valve body is integrally cylindrical. The valve cover is installed above the valve body and is hermetically assembled by welding. A sealing ring is installed between the valve cover and the valve body. A plurality of flow holes H are opened on the bottom surface of the valve body, corresponding one by one to the flow holes of the manifold assembly. The flow holes H at the bottom of the valve body are axially annularly distributed. The flow holes H can be set in a fan shape. A through hole is provided at the center position of the valve cover. The valve core is located inside the valve body. A flow channel is provided on the valve core. A gasket is installed between the valve core and the valve body. The shape of the gasket is the same as the shape of the inner wall of the valve body. The upper end of the valve core has a spline structure, and a matching spline structure is provided on the output end of the actuator. There are a plurality of flow holes F on the side of the valve core. The output end of the actuator is connected to the spline structure at the upper end of the valve core. The actuator provides torque for the valve core to control the rotation of the valve core, which can achieve purposes such as mode calibration and mode switching. After the valve core and the valve body are assembled and installed with the manifold assembly, the flow channels of the manifold assembly correspond to it to realize the connection between specific flow channels of the manifold. The shape of the gasket is the same as the shape of the inner wall of the valve body to ensure the independent sealing of each flow port. The fan-shaped flow holes H reduce the maximum outer diameter of the valve body while ensuring the cross-sectional area of the flow holes. The flow holes on the bottom surface of the valve body are axially annularly distributed. The valve core can connect specific flow holes of the valve body at a specific angle to achieve mode switching. The outer flow channels are annularly distributed at the bottom of the valve body, reducing the volume of the valve body, realizing the overall light weight of the water valve, and making the arrangement of other components and flow channels on the thermal management system more flexible.

[0006] Preferably, three cavities are provided inside the valve core to form three flow channels. The flow channels are staggered. The upper-layer flow channel arches over the lower-layer flow channel. Six flow holes F are opened on the valve core and are evenly distributed on the side wall of the valve core. Each two flow holes F are spaced 60°. One of the flow holes F is divided into two flow holes, spaced 30°. By rotating the valve core, the switching of the flow channels is realized to adjust the flow rate. There are few corners in the flow channels inside the valve, less backflow of the fluid, smaller flow resistance and flow loss, lower pressure drop, and less energy loss.

[0007] Preferably, the actuator consists of an upper housing, a lower housing, a PCBA, a motor, and a gear assembly. The PCBA, the motor, and the gear assembly are assembled in the upper housing and the lower housing. The upper housing and the lower housing are assembled together by welding. A jack is provided on one side of the lower housing for externally connecting a power source and an input signal source. The gear assembly is arranged at the central position to provide torque for the valve body half assembly. When the water valve operates, an external signal is converted into an electric current signal by the PCBA to control the operation of the motor. The gear assembly rotates, and finally drives the valve core to rotate to realize functions such as mode switching of the water valve.

[0008] Preferably, a limiting structure B is provided at the bottom of the valve body, and a limiting structure D matching the limiting structure B is installed at the corresponding position at the bottom of the valve core; the limiting structure D of the valve core cooperates with the limiting structure B in the valve body to realize the angle control of the valve core, so that the valve core can only rotate within a specific angle in the valve body, and the angle of the valve core can be calibrated through the limiting structure.

[0009] Preferably, a plurality of limiting blocks are provided on the inner wall of the valve body, clamping grooves matching the limiting blocks are provided on the outer wall of the sealing gasket, and the lower end surface of the sealing gasket is designed in a grid shape; when the sealing gasket is installed, it is embedded in the limiting blocks, and the limiting blocks can effectively prevent the sealing gasket from rotating or coming off. At the same time, the lower end surface of the sealing gasket is designed in a grid shape, and the compression amount of the sealing gasket can be adjusted while ensuring sealing. When the water valve is working, there is rotational friction between the valve core and the sealing gasket. In order to ensure the lubricity and sealing performance between the two, a lubricating and sealing material can be added on the upper layer of the sealing gasket.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: after the valve core and the valve body are assembled and installed with the manifold assembly, the flow channels of the manifold assembly correspond to them, realizing the connection between specific flow channels of the manifold. The valve core can connect specific through holes of the valve body at a specific angle to realize mode switching. The outer flow channels are annularly distributed at the bottom of the valve body, reducing the volume of the valve body, realizing the overall light weight of the water valve, and making the layout of other components and flow channels on the thermal management system more free.

On the contrary, these embodiments are provided so that the disclosure of the present utility model is more thorough and comprehensive.

[0019] Embodiment 1

The valve body semi-assembly 2 is composed of a valve cover 21, a sealing ring 22, a valve core 23, a gasket 24, and a valve body 25. The valve body 25 is integrally cylindrical. The valve cover 21 is installed above the valve body 25 and is hermetically assembled by welding. A sealing ring 22 is installed between the valve cover 21 and the valve body 25. A number of flow holes H31 are opened on the bottom surface of the valve body 25, corresponding one by one to the flow holes of the manifold assembly, and the flow holes H31 at the bottom of the valve body 25 are annularly distributed along the axis. The flow holes H31 can be set in a fan shape. A through hole is provided at the center position of the valve cover 21. The valve core 23 is located inside the valve body 25. A flow channel is provided on the valve core 23. A gasket 24 is installed between the valve core 23 and the valve body 25. The shape of the gasket 24 is the same as the inner wall shape of the valve body 25. The upper end of the valve core 23 has a spline structure 26, and a matching spline structure is provided on the output end of the actuator 1. There are a number of flow holes F27 on the side of the valve core 23. The actuator 1 is composed of an upper housing 11, a lower housing 12, a PCBA 13, a motor 14, and a gear assembly 15. The PCBA 13, the motor 14, and the gear assembly 15 are assembled in the upper housing 11 and the lower housing 12. The upper housing 11 and the lower housing 12 are assembled together by welding. A socket is provided on one side of the lower housing 12 for externally connecting a power supply and an input signal source. The gear assembly 15 is arranged at the center position to provide torque for the valve body semi-assembly 2. Three cavities are provided inside the valve core 23 to form three flow channels, and the flow channels are staggered. The upper-layer flow channel arches over the lower-layer flow channel. Six flow holes F27 are opened on the valve core 23 and are evenly distributed on the side wall of the valve core 23. Each two flow holes F27 are spaced 60°. One of the flow holes F27 is divided into two flow holes, spaced 30°. A limit structure B30 is provided at the bottom of the valve body 25, and a limit structure D29 matching the limit structure B30 is installed at the corresponding position at the bottom of the valve core 23. A number of limit blocks 28 are provided on the inner wall of the valve body 25, and a clamping groove matching the limit blocks 28 is provided on the outer wall of the gasket 24. The lower end surface of the gasket 24 is designed in a grid shape;

[0021] When the water valve operates, an external signal is converted into a current signal by the PCBA13, which controls the operation of the motor 14. The gear assembly 15 rotates, and finally drives the valve core to rotate, realizing functions such as water valve mode switching. The flow path is switched by rotating the valve core 23 to adjust the flow rate. There are fewer corners in the flow path inside the valve, less fluid backflow, smaller flow resistance and loss, lower pressure drop, and less energy loss. The limit structure D29 of the valve core 23 cooperates with the limit structure B30 inside the valve body 25 to realize the angle control of the valve core 23, so that the valve core 23 can only rotate within a specific angle inside the valve body 25, and the angle of the valve core 23 can be calibrated through the limit structure. When the gasket 24 is installed, it is embedded in the limit block 28. The limit block 28 can effectively prevent the gasket 24 from rotating or coming off. At the same time, the lower end surface of the gasket 24 is designed in a grid shape, and the compression amount of the gasket can be adjusted while ensuring sealing. When the water valve is working, there is rotational friction between the valve core 23 and the gasket 24. In order to ensure the lubricity and sealing between the two, a lubricating and sealing material such as PTFE film can be attached to the upper layer of the gasket.
