Description

Technical Field

[0001] This invention relates to the field of water valve technology, and in particular to an integrated actuator water valve and its control method. Background Technology

[0002] Existing water circuit switching valves mostly adopt a separate assembly structure for the valve body and actuator, and are generally equipped with motor drive or manual adjustment. The overall structure is large and the assembly is complicated, making it difficult to adapt to the narrow installation space of equipment such as automotive thermal management. At the same time, the traditional water valve port structure is simple, and most of them can only realize the path switching of a single scenario. They cannot meet the needs of two-way, three-way, and four-way multi-mode water circuit switching, resulting in poor versatility. The motor drive structure has a slow response speed and low control accuracy, and is prone to adjustment deviation and high energy consumption under long-term high-pressure fluid conditions. Summary of the Invention

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-6 and Figure 9 This is the first embodiment of the present invention, which provides an integrated actuator water valve and its control method. The integrated actuator water valve includes a main component 1, including a housing 11. A flow channel 111 is opened inside the housing 11. A ball valve core 12 is disposed inside the housing 11. A flow groove 12-1 is opened inside the ball valve core 12. A valve stem 13 is connected to the ball valve core 12. The ball valve core 12 and the valve stem 13 are connected by a splined shaft. A top cover 14 is bolted to the housing 11. A sealing ring 112 is provided on the housing 11 and the top cover 14. An actuator 15 is bolted to the top cover 14. The actuator 15 mainly consists of a 24V electromagnetic coil and a control circuit module. The valve consists of a block, a valve core transmission assembly, an angle limiting structure, and a position feedback module. The other end of the valve stem 13 is inserted into the actuator 15. The upper end of the valve stem 13 is connected to the valve core transmission assembly of the integrated electromagnetic actuator 15. The 24V electromagnetic coil generates electromagnetic attraction to drive the valve stem 13 and the ball valve core 12 to complete rotation and axial fine adjustment. With the help of the control circuit, the working status is adjusted in real time, and the ball valve core 12 is precisely driven to rotate to the target angle to realize the on / off switching of the four water interfaces and the multi-proportional flow regulation. For three-way and four-way water valves, different ball valve cores 12 can be replaced to meet the usage requirements. The ball valve core 12 in the figure meets the usage requirements of the three-way water valve.

[0033] A main sealing ring 16 is provided on one side of the flow channel 111. The main sealing ring 16 is used to seal between the flow channel 111 and the ball valve core 12. A secondary sealing ring 17 is provided on the outer sleeve of the valve stem 13. The secondary sealing ring 17 is used to seal between the valve stem 13 and the ball valve core 12. An outer sealing gasket 18 is provided at the bottom of the housing 11. A flange-type mounting bracket is provided at the bottom of the housing 11, which can be tightly connected to the matching parts on the vehicle by four bolts. The outer sealing gasket 18 is used to seal between the housing 11 and the matching parts to ensure no leakage during multi-channel switching and to ensure the reliability of water flow.

[0034] This water valve can flow a 50% water and 50% ethylene glycol mixture, meeting the media flow requirements of automobiles. The connector model is EWCAP-120-S-004-1-Z01 or equivalent, and the female connector is TE_1-1456426-6 or equivalent. The internal leakage of coolant is required to be ≤20mL / Min under 100KPa conditions, and the external leakage of gas is ≤5SCCM under 300KPa pressure. The flow resistance characteristics are yet to be determined. The electrical operating voltage range is 18~32V, the operating current is ≤600mA under 24V conditions, and the sleep current is ≤100μA. The operating temperature range is -40~100℃, the circuit switching time is ≤10S, the operating noise at a distance of 500mm is ≤55dB(A), the protection level reaches IP67 and IP6K9K, the burst pressure is greater than 700KPa, and the service life is greater than 200,000 cycles.

[0035] Auxiliary component 2, located on one side of ball valve core 12, includes auxiliary component 21. By setting auxiliary component 21, when the water valve needs to be used as a two-way water valve, the valve core 12 corresponding to the three-way water valve can be directly changed to meet the usage scenario of the two-way water valve without replacing the new valve core 12.

[0036] A sealing plate 211 is slidably disposed inside the ball valve core 12. A push block 212 is fixed on one side of the sealing plate 211. The push block 212 is rectangular. The sealing plate 211 can contact the flow channel 111. By controlling the sealing plate 211 to move towards the flow channel 111 and tightly fitting with the main sealing ring 16 on the flow channel 111, the flow channel 111 can be blocked, thereby turning the tee into a two-way valve.

[0037] The auxiliary component 2 also includes an adjustment member 22 located on one side of the push block 212. The adjustment member 22 is configured to push the push block 212 to move, thereby causing the sealing plate 211 to seal one of the flow channels 111.

[0038] Example 2, refer to Figures 3-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, a first protrusion 213 is fixed to the side of the sealing plate 211, and a corresponding first groove 12-2 is provided in the ball valve core 12. The first protrusion 213 can engage with the first groove 12-2. Through the cooperation of the first protrusion 213 and the first groove 12-2, the relative position of the sealing plate 211 and the ball valve core 12 can be locked. A rubber layer is provided on the surface of the sealing plate 211. When the first protrusion 213 and the first groove 12-2 engage, the rubber layer is compressed, so that the sealing plate 211 and the ball valve core 12 can fit tightly together.

[0040] Specifically, there are two first protrusions 213, and the number of first grooves 12-2 is the same. In the initial state, the two are engaged with each other. When the pusher 212 is pushed, the sealing plate 211 tends to move towards the flow channel 111. The first protrusions 213 will squeeze and rub against the inner wall of the first groove 12-2, which will then separate the two. Then the sealing plate 211 is unlocked, so that it can move towards the flow channel 111 and fit tightly against the main sealing ring 16 on the flow channel 111, which can block the flow channel 111, thereby turning the tee into a two-way.

[0041] Specifically, the adjusting component 22 includes a screw 221 connected to the housing 11 by a bearing. A rectangular sleeve 222 is externally threaded onto the screw 221. The rectangular sleeve 222 has a threaded groove inside, which restricts its rotation. Therefore, when the screw 221 is rotated, the rectangular sleeve 222 can slide radially along the screw 221 and move closer to the push block 212. Eventually, the rectangular sleeve 222 contacts the push block 212. After that, the screw 221 continues to rotate, causing the rectangular sleeve 222 to continue to move, which will push the push block 212 to move, thereby causing the sealing plate 211 to move towards the flow channel 111.

[0042] The reverse rotation of screw 221 can drive rectangular sleeve 222 to move in the opposite direction.

[0043] Specifically, an extension block 223 is fixed to the outside of the rectangular sleeve 222, and a guide post 224 is fixed inside the housing 11. The extension block 223 has a guide groove corresponding to the guide post 224. Through the cooperation of the guide post 224 and the extension block 223, the two will jointly restrict the rectangular sleeve 222 from rotating, and it can only slide horizontally in a specific direction.

[0044] Specifically, there are two guide posts 224 and two extension blocks 223. A support block 225 is fixed to the end of the guide post 224. The support block 225 is fixed to the inner wall of the housing 11. The support block 225 is provided to provide auxiliary support for the guide post 224.

[0045] In the initial state, the rectangular sleeve 222 will be located at the position furthest from the ball valve core 12. At this time, the rectangular sleeve 222 will not interfere with the rotation of the ball valve core 12, and the push block 212 will be completely inside the ball valve core 12. When it is necessary to change the three-way valve to a two-way valve, rotate the screw 221 to first drive the rectangular sleeve 222 to approach the push block 212. Only after it contacts the push block 212 can it further drive the push block 212 to move.

[0046] Example 3, referring to Figures 3-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a second protrusion 226 is fixed at the end of the rectangular sleeve 222, and a second groove 212-1 corresponding to the second protrusion 226 is opened at the end of the push block 212. Through the cooperation of the second protrusion 226 and the second groove 212-1, the relative positions of the rectangular sleeve 222 and the block 212 can be locked.

[0048] The force required for the second protrusion 226 and the second groove 212-1 to change from an engaged state to a disengaged state is greater than the force required to change the engaged state of the first protrusion 213 and the first groove 12-2.

[0049] In the initial state, there is a certain gap between the second protrusion 226 and the second groove 212-1. As the screw 221 rotates, the rectangular sleeve 222 approaches the push block 212, and then a pushing force is applied to the push block 212. The first protrusion 213 and the first groove 12-2 will separate, causing the sealing plate 211 to move towards the flow channel 111 and fit tightly with the main sealing ring 16 on the flow channel 111, thus blocking the flow channel 111. At this time, the sealing plate 211 cannot continue to move. Therefore, as the rectangular sleeve 222 moves further, the second protrusion 226 and the second groove 212-1 will engage.

[0050] When used as a three-way water valve, the screw 221 is rotated in the opposite direction, causing the rectangular sleeve 222 to move in the opposite direction. Under the action of the second protrusion 226 and the second groove 212-1, the push block 212 and the sealing plate 211 move in the opposite direction synchronously. When the sealing plate 211 is about to move to the initial position, the first protrusion 213 and the first groove 12-2 will gradually engage. At this time, the second protrusion 226 and the second groove 212-1 will continue to maintain the engagement state. When the sealing plate 211 moves to the limit position, the rectangular sleeve 222 continues to rotate in the opposite direction, which will cause the second protrusion 226 and the second groove 212-1 to separate. Finally, the rectangular sleeve 222, the sealing plate 211 and the push block 212 all return to the initial position.

[0051] Specifically, one end of the screw 221 extends through to the outside of the housing 11, and a handle 227 is fixed at this end. A shaft seal assembly is provided at the connection point between the screw 221 and the bearing of the housing 11, so that the medium flowing inside the housing 11 will not leak out from the screw 221.

[0052] Specifically, there are four flow channels 111, which are evenly distributed in a circle inside the housing 11.

[0053] Specifically, the internal control unit of actuator 15 sends an angle adjustment command, the internal electromagnetic coil of actuator 15 is energized, and the valve stem 13 is driven to rotate through electromagnetic attraction. The valve stem drives the ball valve core 12 to rotate synchronously to the target angle. Different rotation angles of the ball valve core 12 can switch the on / off state of each flow channel, and precisely control the on / off state and switching of the four water circuit interfaces.

[0054] When in use, if it is necessary to convert the three-way water valve into a two-way water valve, first control the actuator 15 so that the position of the flow groove 12-1 is aligned with the three flow channels 111, so that the push block 212 can be in a coaxial position with the rectangular sleeve 222.

[0055] Rotating handle 227 drives screw 221 to rotate. As screw 221 rotates, rectangular sleeve 222 approaches push block 212 and then applies a pushing force to push block 212. The first protrusion 213 and the first groove 12-2 will separate, driving sealing plate 211 to move towards flow channel 111 and tightly fit with the main sealing ring 16 on flow channel 111, thus blocking flow channel 111. At this time, sealing plate 211 cannot move further. Therefore, as rectangular sleeve 222 moves further, second protrusion 226 and second groove 212-1 will engage, and sealing plate 211 will continue to block flow channel 111. At this time, only two flow channels 111 can be connected.

[0056] When used as a three-way water valve, the screw 221 is rotated in the opposite direction, causing the rectangular sleeve 222 to move in the opposite direction. Under the action of the second protrusion 226 and the second groove 212-1, the rectangular sleeve 222 drives the push block 212 and the sealing plate 211 to move in the opposite direction synchronously. When the sealing plate 211 is about to move to the initial position, the first protrusion 213 and the first groove 12-2 will gradually engage. At this time, the second protrusion 226 and the second groove 212-1 will continue to maintain the engaging state. When the sealing plate 211 moves to the limit position, the rectangular sleeve 222 continues to rotate in the opposite direction, which will cause the second protrusion 226 and the second groove 212-1 to separate. Finally, the rectangular sleeve 222, the sealing plate 211 and the push block 212 all return to the initial position.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
