Description

Technical Field

[0001] The present invention belongs to the technical field of fluid equipment, and particularly relates to a proportionally adjustable integrated valve. Background Art

[0002] With the progress of technology and the improvement of control systems, the control requirements for fluid circuits are getting higher and higher. The equipment with such fluid circuits has more and more complete functions, involving various equipment devices such as vehicles and new energy vehicles, especially the energy exchange control of new energy vehicles, such as the temperature control of the passenger compartment, air conditioning system, power battery, electronic control system, etc.

[0003] At present, the thermal management control system of new energy vehicles is becoming more and more complex. In order to achieve various control and operation modes of the whole vehicle, multiple reversing valves for controlling the fluid flow direction and multiple driving mechanisms are involved in the fluid circuit, and the flow channel layout is complex. In order to achieve the precise distribution of the cooling flow rate of the passenger compartment and the battery pack, the thermal management control system needs to achieve proportional regulation of the loop flow rate. Therefore, a proportional valve needs to be added to the thermal management system, which undoubtedly makes the complexity of the whole control loop higher and the manufacturing cost higher. Therefore, a control device that can integrate multiple reversing valves and driving mechanisms is needed, which is beneficial to reducing the manufacturing cost of the thermal management system, saving layout space, and reducing the number of coolant pipes. Summary of the Invention

[0004] Aiming at the above existing problems, the technical object of the present invention is to propose a proportionally adjustable integrated valve, so as to achieve the effect that multiple fluid passages can be controlled by one integrated valve.

[0005] In order to achieve the above object, the following technical solutions are proposed:

[0006] The proportionally adjustable integrated valve of the present invention includes a driven active valve core and a driven valve core arranged below the active valve core, and the active valve core and the driven valve core are rotatably arranged in the valve body;

[0007] The active valve core includes a first top plate and a first bottom plate, and at least one set of first fluid channels that are connected and can flow out of the valve body is formed between the first top plate and the first bottom plate;

[0008] The driven valve core includes a first plate body and a second plate body, and several second fluid channels that can radially flow outwards to the valve body are formed between the first plate body and the second plate body; A limiting structure is arranged between the active valve core and the driven valve core, which can make the active valve core drive the driven valve core to rotate;

[0009] Several fluid ports that can be communicated with the first fluid channels and the second fluid channels are arranged on the valve body.

[0010] In some embodiments, a third plate body is further provided below the second plate body of the driven valve core provided by the present invention. At least one third fluid flow-through is formed between the second plate body and the third plate body, and a fluid port communicating with the third fluid flow-through is provided on the valve body.

[0011] In some embodiments, the number of fluid ports communicating with the first fluid channel, the second fluid channel, and the third fluid flow-through is 3 each, and each layer of the fluid ports is arranged in 3 horizontally and vertically.

[0012] In some embodiments, the first fluid channel can simultaneously connect two adjacent fluid ports, and can at least partially connect two separated fluid ports.

[0013] In some embodiments, the second fluid channel can simultaneously connect two adjacent fluid ports, and can at least partially connect two separated fluid ports.

[0014] In some embodiments, the second fluid channel and the third fluid flow-through have the same structure.

[0015] To better implement the technical solution, a driving mechanism is connected to the active valve core.

[0016] To better implement the technical solution, a sealing member is further provided between the fluid port portion of the valve body and the active valve core and the driven valve core.

[0017] To better implement the technical solution, the limiting structure includes a block provided at the bottom of the active valve core and extending into the top of the driven valve core, and a set distance is provided between the block and the top structure of the driven valve core in the horizontal direction.

[0018] To better implement the technical solution, the set distance between the block and the top structure of the driven valve core enables the rotation angle of the active valve core to reach half of the central angle occupied by the first fluid channel.

[0019] Due to the adoption of the above technical solution, the beneficial effects of the present invention at least include:

[0020] Through the structural settings of the active valve core and the driven valve core, the functions of multiple conventional valves can be integrated into one, and the control mechanism is greatly reduced, thereby reducing costs, reducing weight, reducing the number of coolant pipes, reducing space requirements, and having important economic value and technical value; by controlling the active valve core with one control structure, the active valve core drives the driven valve core to rotate, which can improve the control flexibility, and does not increase the number of driving mechanisms, and at the same time can achieve proportional adjustment; in addition, the formed multi-layer flow channels are simple to process, further reducing costs and increasing its social value.

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The present invention will be described in detail below with reference to the accompanying drawings.

[0032] As Figures 1 to 7As shown in the figure, a proportionally adjustable integrated valve includes a driven active valve core 2 and a driven valve core 3 disposed below the active valve core 2. The active valve core 2 and the driven valve core 3 are rotatably disposed in a valve body 1. Among them, the active valve core 2 is drivingly installed, and the driving device can be in various forms, including but not limited to an electric motor. The active valve core 2 includes a first top plate 21 and a first bottom plate 22. At least one set of first fluid channels 01 that are connected and can flow out of the valve body 1 are formed between the first top plate 21 and the first bottom plate 22. When the active valve core 2 rotates to the working position, the fluid channels formed between the first top plate 21 and the first bottom plate 22 can communicate with the flow ports 10 provided on the valve body 1. The number of the communicated flow ports 10 is determined by the number of the flow ports 10 that need to be communicated according to the setting and the number of the flow ports 10 covered by the first fluid channels 01 on the active valve core 2. The number of the flow ports 10 covered by the first fluid channels 01 or the area / size of the covered flow ports 10 are used to determine which flow ports are opened or closed or the opening degree of the opened flow ports.

[0033] To better implement this technical solution, the driven valve core 3 includes a first plate body 31 and a second plate body 32. A plurality of second fluid channels 02 that can flow radially outward or nearly radially outward to at least one of the valve bodies 1 are formed between the first plate body 31 and the second plate body 32. A limiting structure 5 is provided between the active valve core 2 and the driven valve core 3, which can enable the active valve core 2 to drive the driven valve core 3 to rotate. The limiting structure 5 includes a block 51 provided at the bottom of the active valve core 2 and extending into the top of the driven valve core 3. A set distance is provided between the block 51 and the top structure of the driven valve core 3 in the horizontal direction. One more specific implementation manner is that the set distance between the block 51 and the top structure of the driven valve core 3 can enable the rotation angle of the active valve core 2 to reach half of the central angle occupied by the first fluid channels 01. More specifically, a recess 52 capable of accommodating the block 51 is provided at the top of the driven valve core 3. The recess 52 is larger than the space occupied by the block 51, so that the block 51 can rotate at a certain angle in the recess 52 without causing the driven valve core 3 to rotate, and the rotation angle can be set according to needs. A plurality of flow ports 10 that can communicate with the first fluid channels 01 and the second fluid channels 02 are provided on the valve body 1, and the number of the flow ports 10 can be set according to needs.

[0034] In order to better implement the present invention, in some embodiments, a third plate body 33 is further provided below the second plate body 32 of the driven spool valve 3, and at least one third fluid passage 03 is formed between the second plate body 32 and the third plate body 33. A fluid port 10 is provided on the valve body 1 and can communicate with the third fluid passage 03. In order to better implement the present invention, in some embodiments, the number of fluid ports communicating with the first fluid passage 01, the second fluid passage 02, and the third fluid passage 03 is 3 each, and each layer of the fluid ports 10 is arranged in 3 horizontally and vertically.

[0035] In order to better implement the present invention, in some embodiments, the first fluid passage 01 can simultaneously connect two adjacent fluid ports 10, and can at least partially connect two separated fluid ports 10.

[0036] The second fluid passage 02 can simultaneously connect two adjacent fluid ports 10, and can at least partially connect two separated fluid ports 10. The second fluid passage 02 has the same structure as the third fluid passage 03. The active spool valve 2 is connected to a driving mechanism 4, and the driving mechanism 4 can be motor-driven. A seal 6 is further provided between the fluid port 10 part of the valve body 1, the active spool valve 2, and the driven spool valve 3, thereby improving the sealing performance between the spool valve and the valve body.

[0037] For a more specific implementation of the present invention, the active spool valve 2 is evenly divided into 8 parts, and two mutually communicating parts are used as the first fluid passage 01, and the central angle occupied by it is about 90°. The number of fluid ports 10 provided on the valve body 1 and communicating with the first fluid passage 01 is 3. The fluid ports 10 are A1, A2, and A3 from left to right respectively. The central angles occupied by the second fluid passage 02 and the third fluid passage 03 provided on the driven spool valve 3 are also about 90°. The fluid ports 10 that the second fluid passage 02 can communicate with are B1, B2, and B3 respectively, and the fluid ports 10 that the third fluid passage 03 can communicate with are C1, C2, and C3 respectively. Each layer of the fluid ports 10 is arranged in 3 horizontally and vertically, and can also be 4 or other numbers. Here, an example is given for a clearer explanation. Among them, the size of the first fluid passage 01 is set to be able to simultaneously connect two adjacent fluid ports 10, and can at least partially connect two separated fluid passages 01, that is, it can connect A2 and A3, or can connect A1, A2, and A3 simultaneously, or can also partially connect A1 and A3 that are separated, so as to achieve the required control of fluid connection. In addition, the setting methods of the second fluid passage 02 and the fluid ports B1, B2, B3, and the third fluid passage 03 and the fluid ports C1, C2, C3 are the same. In addition, the central angle occupied by the block 51 is 45 degrees or close to 45 degrees, and the central angle occupied by the concave part 52 is 90 degrees or close to 90 degrees, such as Figure 7As shown, the central angles occupied by the first fluid passage 01, the second fluid passage 02, and the third fluid passage 03 are 90 degrees or close to 90 degrees, so that the following connection modes can be obtained:

[0038] When the active valve core 2 and the driven valve core 3 are in the initial position, at this time, the side surface of the block 51 in the counterclockwise direction contacts the side surface of the recess 52, so that the active valve core 2 can just drive the driven valve core 3 to rotate. In the initial position, A1 is connected to A2, B1 is connected to B2, and C1 is connected to C2, as Figure 3 shown. Figure 3 In [Figure 3-1], 3-1 is the active valve core 2, and 3-2 and 3-3 are the driven valve cores 3;

[0039] In the initial position, control the active valve core 2 to rotate counterclockwise by about 35 degrees, and at the same time the driven valve core 3 also rotates synchronously, so that A2 is connected to A3, B2 is connected to B3, and C2 is connected to C3, as Figure 4 shown, where the rotation angle is reasonably determined according to the specific settings of the valve, and the control effect is sufficient. The rotation angle enables the above-mentioned communication ports to be connected;

[0040] In the initial position, control the active valve core 2 to rotate counterclockwise by about 35 degrees, and at the same time the driven valve core 3 also rotates synchronously, so that A2 is connected to A3, B2 is connected to B3, and C2 is connected to C3. Then control the active valve core 2 to reverse (i.e., rotate clockwise) by about 15 degrees to realize the connection of A1, A2, and A3 by the active valve core 2 and achieve proportional adjustment, as Figure 5 shown;

[0041] In the initial position, control the active valve core 2 to rotate counterclockwise by about 0-35 degrees, and at the same time the driven valve core 3 also rotates synchronously by the same angle, so that A1, A2, and A3 are connected, B1, B2, and B3 are connected, and C1, C2, and C3 are connected to reach the fully open state, as Figure 6 shown.

[0042] The rotation angles of the above-mentioned active valve core 2 and driven valve core 3 are not unique and depend on the size of the fluid passage on the valve core and the size / width of the communication port provided on the valve body and the distance between the communication ports. During the rotation process of the above-mentioned valve core, the rotation angle is reasonably determined according to the specific settings of the valve to achieve the control purpose. The rotation angle enables the above-mentioned communication ports to be connected or blocked.

[0043] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. Although the present application has been disclosed above with the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, may make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present application, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still fall within the scope of the present application solution.
