Description

[Technical field]

[0001] This application claims priority to a Chinese patent application filed on December 31, 2020, bearing application number 202011625561.2 and titled "Fluid Control Device", and a Chinese patent application filed on December 31, 2020, bearing application number 202011626190.X and titled "Fluid Control Assembly and Fluid Control Device", the entire contents of which are incorporated herein by reference.

[0002] The present invention is in the field of fluid control, and more particularly, relates to fluid control assemblies and devices. [Background technology]

[0003] Since the fluid flow paths are switched in the vehicle thermal management system, the vehicle thermal management system uses a plurality of flow path switching valves to control the flow paths. A flow path switching valve has a valve body and a valve element housed inside the valve body. A typical flow path switching valve has a configuration similar to that shown in Figure 1, with two or more connecting pipes 2 protruding from the periphery of a valve body 1, an external pipeline connected to the connecting pipes, and the valve element moving inside the valve body to change the communication form of the flow path.

[0004] In many cases, the vehicle thermal management systems used in different vehicle models are different, some may use a four-way flow valve and some may use a five-way flow valve. Thus, factories that manufacture flow path diverter valves need to manufacture various styles of flow path diverter valves to suit different systems, and furthermore, customers may have different requirements for the location of the connection ports for other reasons. For this reason, it is necessary to manufacture multiple types of flow path switching valves to meet customer requirements, and since the product shapes are different, the production line for producing these products must be changed. Therefore, manufacturing various types of flow path switching valves results in large input costs for the manufacturing plant. Summary of the Invention [Problem to be solved by the invention]

[0010] Hereinafter, a specific embodiment to which the configuration of the present invention is applied will be described in detail.

[0011] As one embodiment, a fluid control device 10 is shown with reference to FIGS. The fluid control device 10 can be used to switch flow paths. Fluid control device 10 includes a fluid control assembly 11 and a fluid connection 16 . The fluid control assembly 11 mainly includes a valve disc member 12 (shown in FIG. 5), a valve body member 15 and a control member 14, and the fluid control assembly 11 has a valve chamber, and at least a portion of the valve disc member 12 is located in the valve chamber. The control member 14 can control the movement of the valve body member 12 in the valve chamber, and the movement of the valve body member 12 can, for example, cause the valve body member 12 to rotate or move, thereby enabling communication or switching of the flow path of the fluid control device.

[0012] The fluid control device provided by the embodiments of the present invention is not limited to a valve, and may be a device applied to other fluid control systems such as a pump, a heat exchanger, etc., and may be an integrated component having multiple functions, such as an integrated component of a heat exchanger and a valve, an integrated component of a valve and a pump, or an integrated component of a pump and a heat exchanger.

[0013] The fluid control device 10 has, for example, two connection ports, and the flow path between the two connection ports can be made to communicate or not communicate by the movement of the valve body member 12. The fluid control device 10 has, for example, three connection ports, and two of the connection ports can be selectively brought into communication by the movement of the valve body member 12. The fluid control device 10 may have, for example, four or more connection ports, and by movement of the valve body member 12, it is possible to realize continuity of the flow paths between the different connection ports, thereby realizing the function of switching and connecting the flow paths.

[0014] The valve body member 15 has a main body portion 151 forming at least a portion of the peripheral wall of the valve chamber and a protrusion portion 152 protruding from a peripheral wall 155 of the main body portion 151, and the fluid control device has a first flow path 13 (shown in FIG. 5) located inside the main body portion 151, the protrusion portion 152 having two or more second flow paths 156 that can communicate with the first flow path 13, the protrusion portion 152 having two or more lugs 157 having the second flow paths 156, and the communication ports 1561 of the second flow paths 156 of at least a portion of the lugs 157 are directed to the flow path connection portion 16. In this embodiment, the communication ports 1561 of the second flow paths 156 of all the lugs 157 are directed to a flow path connection portion 16 having two or more third flow paths 161, the second flow paths 156 and the third flow paths 161 are correspondingly connected to each other, the second flow paths 156 and the third flow paths 161 which are connected to each other are hermetically sealed, and the flow path connection portion 16 and the valve body member 15 are hermetically sealed. Among them, the communication ports 1561 of at least a portion of the second flow passages 156 face in the same direction and are located in the same plane, which facilitates installation of the fluid control assembly 11 .

[0015] In this way, the communication port 1561 of the second flow path of the valve body member 15 can be communicated with the third flow path 161 of the flow path connection part 16, and both of the fluid inlets and outlets of the fluid control device 10 are provided in the flow path connection part 16. The flow path connection part 16 realizes the guidance and branching of the flow path, and the connection of the flow path connection part 16 to an external pipeline or passage, making it easy to arrange the pipeline of the connection port and making the overall structure compact.

[0016] In some embodiments, the fluid connection portion 16 is integrally injection molded, the body portion 151 and the protrusion portion 152 are integrally injection molded, and the fluid connection portion 16 is fixed to the protrusion portion 152 by welding. The flow path connection portion 16 can be made of a plastic material and formed by injection molding, the valve body member 15 can also be formed by injection molding of a plastic material, and the welding between the flow path connection portion 16 and the protrusion portion 152 can be performed by a plastic welding method. The flow path connecting portion 16 is integrally injection molded, the valve body member 15 is integrally injection molded, and the flow path connecting portion 16 and the valve body member 15 are fixed by welding, so that the processing is simple. In some embodiments, the communication ports 1561 of the second flow paths 156 are oriented in the same direction and are located in the same plane, the communication ports 1618 (shown in FIG. 8 ) of the third flow paths 161 are located in the same plane, and the plane in which the communication ports 1561 of the second flow paths 156 are located is welded to the plane in which the communication ports 1618 of the third flow paths 161 are located.

[0017] The axial direction of the main body portion 151 is the axial direction H of the valve body member 15, and at least a part of the protrusion 152 protrudes from the main body portion 151 along the radial direction D of the valve body member 15, and each lug 157 has a tip portion 1571 facing the flow path connection portion 16, and the tip portion 1571 is provided with a communication port 1561 of the second flow path 156. The tip portion 1571 has a bottom end surface 1575, and in a cross section parallel to the radial direction of the valve body member 15, the bottom end surfaces 1575 of at least two of the lugs 157 are located on the same cross section. By positioning at least two of the bottom end surfaces 1575 on the same cross section, it becomes easier to seal and fix them to the flow path connection portion 16, and by sealing and fixing one cross section, it becomes possible to realize sealed installation of at least two second flow path communication ports 1561 and the third flow path 161, which is further advantageous for sealing operations, facilitates optimization of the configuration, and is easy to assemble.

[0018] In this embodiment, referring to Figures 3 to 5, the protrusion 152 has five lugs 157 arranged along the circumferential direction of the main body portion 151, each of the lugs 157 also having a tip portion 1571, each of the tip portions 1571 having a bottom end surface 1575, and the five bottom end surfaces 1575 are in the same cross section in a cross section parallel to the radial direction of the valve body member 15. The five bottom end faces 1575 on the same cross section as the flow passage connection portion 16 are fixed by welding at the same time, which simplifies the assembly process and reduces the production cost.

[0019] In this embodiment, the five lugs 157 are spaced apart, and the tip portions 1571 thereof are also spaced apart. However, in some embodiments, the lugs 157 may be adjacently located.

[0020] Here, the term "protruding from the main body portion 151 along the radial direction of the valve body member 15" means that the protruding portion 152 has a portion that protrudes from the main body portion 151 in the radial direction of the valve body member 15, and is not limited to the protruding portion 152 as a whole protruding from the main body portion 151 in the same radial direction. Here, protruding in the radial direction means having a portion that protrudes in the radial direction relative to the peripheral wall 155 of the main body portion 151.

[0021] The projection 152 has connecting portions 158 located between and connecting outer walls 1572 of adjacent lugs 157 . The connection portion 158 can increase the mechanical strength of the lug 157, thereby contributing to improved stability when the valve body member 15 and the flow passage connection portion 16 are assembled.

[0022] The connection portion 158 has a bottom end surface 1581, which may be flush with the bottom end surface 1575 of the lug 157, and the connection portion 158 may be welded to the flow passage connection portion 16. In this way, when the bottom end surface 1575 of the lug 157 is welded to the flow path connection portion 16, the connection portion 158 can also be welded and fixed to the flow path connection portion 16 at the same time, which contributes to improving the robustness of the weld between the lug 157 and the flow path connection portion 16.

[0023] In a vertical cross section passing through the axis of the main body 151, the lug 157 has a root portion 1573 and an outer edge portion 1574, and the communication port 1561 of the second flow passage 156 is located between the root portion 1573 and the outer edge portion 1574. In a radial cross section of the main body portion 151 , the distance between at least a portion of the outer edge portion 1574 and the axis of the main body portion 151 is greater than the distance between the root portion 1573 and the axis of the main body portion 151 .

[0024] In this embodiment, the root portion 1573 extends from the peripheral wall 155 of the valve body member 15 in a direction away from the valve chamber and extends along the axial direction of the main body portion 151, and the tip portion 1571 of the root portion 1573 forms a part of the wall of the communication port 1561 of the second flow path.

[0025] Since the distance between at least a portion of the outer edge portion 1574 and the axis of the main body portion 151 is greater than the distance between the root portion 1573 and the axis of the main body portion 151, the lugs 157 are easy to connect to the flow path connection portion 16, and at the same time, if necessary, the bottom end surfaces 1575 of each lug 157 can all be positioned in the same plane, facilitating the design of the configuration of the flow path connection portion 16. When customer requirements are different, one fluid control assembly 11 can be combined with a flow path connection portion 16 having a different connection port shape to meet the customer requirements, thereby realizing standardized production of the fluid control assembly 11 and reducing costs.

[0026] In this embodiment, the valve body member 15 has a tubular structure, the valve body member 15 has a first end 153 and a second end 154 along the axial direction of the valve body member 15, the control member 14 is located on the first end 153 side, the lug 157 protrudes from the second end 154, and the flow path connection portion 16 is assembled to the second end 154 of the valve body member 15, so that the structure is simple, the connection between the lug 157 and the flow path connection portion 16 is facilitated, and the connection structure becomes more compact.

[0027] In this embodiment, the communication ports 1618 of each third flow path 161 are directed toward the valve body member 15, the communication ports 1618 of each third flow path 161 and the communication ports 1561 of each second flow path are provided in correspondence with each other, the flow path connection portion 16 has the same number of third flow paths 161 as the second flow paths 156, and each second flow path 156 and the third flow path 161 are in one-to-one correspondence. The flow path connection part 16 is welded and fixed to the valve body member 15, thereby switching and connecting the second flow path 156 of the valve body member 15 to the flow path connection part 16, and communicating with an external pipeline or passage via the flow path connection part 16, making the structure easy to connect and convenient to install and arrange.

[0028] With reference to FIG. 8, the flow path connection portion 16 has a main body portion 167 and a fitting portion 168 . The main body portion 167 and the fitting portion 168 are of an integral structure, the fitting portion 168 protrudes integrally from the main body portion 167, the fitting portion 168 has communication ports 1618 of the third flow path 161, the main body portion 167 is provided with connection holes 1671 corresponding to the number of communication ports 1618 of the third flow path 161, and the flow path connection portion 16 can be formed by integral injection molding. The fittings 168 have welded portions 1681 surrounding the communication ports 1618 of the third flow paths 161, and the welded portions 1681 in each fitting 168 can be independently installed.

[0029] In another embodiment, the body portion 167 may have welds located between adjacent mating portions 168 and used to improve weld strength.

[0030] The valve body member 12 may have a variety of configurations, such as a spherical shape, a cylindrical shape, or an irregular shape, and may have an internal hole or a communicating groove on the side. This specification is not particularly limited thereto, and various valve body members 12 having the functions described herein are considered to be included in this specification.

Since the distance between at least a portion of the outer edge portion 1574 and the axis of the main body portion 151 is greater than the distance between the root portion 1573 and the axis of the main body portion 151, the lugs 157 are easy to connect to the flow path connection portion 16, and at the same time, if necessary, the bottom end surfaces 1575 of each lug 157 can all be positioned in the same plane, facilitating the design of the configuration of the flow path connection portion 16. When customer requirements are different, one fluid control assembly 11 can be combined with a flow path connection part 16 having a different connection port shape to meet the customer requirements, thereby realizing standardized production of the fluid control assembly 11 and reducing costs.

[0048] In this embodiment, the communication port 1618 of each third flow path 161 is directed toward the valve body member 15, and at least one of the third flow paths 161 of the flow path connection portion 16 has a first portion 1611 of the third flow path and a second portion 1612 of the third flow path, and the first portion 1611 of the third flow path and the second portion 1612 of the third flow path are independently installed in the flow path connection portion 16, and the first portion 1611 of the third flow path and the second portion 1612 of the third flow path are connected to the same second flow path 156.

[0049] In this embodiment, the fluid control assembly 11 has five lugs 157 , each lug 157 having a second flow passage 156 . The flow path connection portion 16 has five flow guide portions 162, each of which corresponds to each lug 157, and each of the flow guide portions 162 has a first portion 1611 of a third flow path and a second portion 1612 of the third flow path which are independently installed, and fluid can flow independently through the first portion 1611 of the third flow path and the second portion 1612 of the third flow path. In this manner, the second flow passage 156 of each lug 157 is formed into two sub-flow passages by a switching connection via the flow passage connection portion 16, and thus, when the fluid control assembly 11 has five flow passages, it is formed into ten flow passages by a switching connection via the flow passage connection portion 16, making it applicable to systems that require switching of flow passages of ten connection ports in a vehicle thermal management system.

[0050] In another embodiment, refer to FIG. 17, which shows a diagram of a fluid connection 16. Since none of the flow guide sections 162 of the flow path connection section 16 need have the first portion 1611 of the third flow path and the second portion 1612 of the third flow path, but may have one, two, three or four of them, the fluid control assembly 11 of this embodiment can be used in cases where there are five, six, seven, eight, nine or ten connection ports.

[0051] In other embodiments, in application scenarios where there are less than five connection ports, the second flow paths 156 of the two lugs 157 of the valve body member 15 can also be mixed in the flow path connection portion 16, that is, the flow path connection portion 16 can realize the requirement of flow path switching for four connection ports. The above number of connection ports is merely an example, and the number of connection ports can be arbitrarily adjusted according to actual circumstances.

[0052] In another embodiment, FIG. 20 shows another fluid connection 16 .

[0053] The communication port 1618 of the third flow path 161 of the flow path connection portion 16 and the communication port 1561 of the second flow path are provided corresponding to each other, and the third flow path 161 has a trunk portion 1613, a first branch portion 1614, a second branch portion 1615 and a third branch portion 1617, and the communication port 1618 of the third flow path 161 is located in the trunk portion 1613, and the first branch portion 1614, the second branch portion 1615 and the third branch portion 1617 are individually connected to the trunk portion 1613. In this manner, fluid from one second flow path 156 with lug 157 enters this third flow path 161 and is diverted from the trunk portion 1613 to the first branch portion 1614, the second branch portion 1615 and the third branch portion 1617 to accommodate different system requirements.

[0054] 18, 19a and 19b, one embodiment of a fluid control device 40 is shown.

[0055] FIG. 18 illustrates a fluid control device 40 that is generally similar to the fluid control device illustrated in FIG. At least the difference lies in that the configuration of the valve body member 15 and the configuration of the flow passage connection portion 16 are different. In this embodiment, the peripheral wall portion of the lug 157 of the valve body member 15 and the outer circumferential wall of the main body portion 151 are spaced apart from each other, and along the extension direction of the lug 157, as shown in FIG. 18, the lug 157 extends in a curved shape, and along the direction perpendicular to the fluid flow direction, the cross section of the lug 157 is annular, thereby reducing the fluid resistance when the fluid flows through the lug 157. In this case, the lug 157 can be welded and fixed to the main body portion 151 and sealed, and the flow path connection portion 16 has a main body portion 167 and a fitting portion 168 protruding from this main body portion 167, and the fitting portion 168 has a welding portion 1681 welded to the lug 157. In this embodiment, the valve body member 15 has a tubular structure, the valve body member 15 has a first end 153 and a second end 154 along the axial direction of the valve body member 15, the fluid control assembly 11 has a control member 14 located on the first end 153 side, and a lug 157 protrudes from between the first end 153 and the second end 154.

[0056] The axial direction of the main body portion 151 is the axial direction of the valve body member 15, the protrusions 152 protrude from the main body portion 151 along the radial direction of the valve body member 15, and each lug 157 has a tip portion 1571 facing the flow path connection portion 16, and the tip portion 1571 is provided with a communication port 1561 of the second flow path. The tip portion 1571 has a bottom end surface 1575, and in a cross section parallel to the radial direction of the valve body member 15, at least two of the bottom end surfaces 1575 are located on the same cross section. By positioning at least two of the bottom end surfaces 1575 on the same cross section, it becomes easier to seal and fix them to the flow path connection portion 16, and by sealing and fixing one cross section, it becomes possible to realize sealed installation of at least two second flow path communication ports 1561, which is further advantageous for sealing operations, facilitates optimization of the configuration, and is easy to assemble.

[0057] In a longitudinal cross section passing through the axis of the main body portion 151, the lug 157 has a root portion 1573 and an outer edge portion 1574, and the second flow path communication port 1561 is located between the root portion 1573 and the outer edge portion 1574, and in a radial cross section of the main body portion 151, the distance between at least a portion of the outer edge portion 1574 and the axis of the main body portion 151 is greater than the distance between the root portion 1573 and the axis of the main body portion 151.

[0058] FIG. 21 shows a schematic diagram of a fluid control device 50, in which the axial direction of the main body 151 is the axial direction of the valve body member 15, the lugs 157 protrude from the main body 151 along the radial direction of the valve body member 15, and each lug 157 has a tip 1571 facing the flow path connection portion 16, and the tip 1571 is provided with a communication port 1561 for the second flow path. The tip 1571 has a bottom end surface 1575, and in a cross section forming an angle of 0 to 90° with the axial direction of the valve body member 15, at least two of the bottom end surfaces 1575 are located on the same cross section.

[0059] In another embodiment, the root portion 1573 extends to the peripheral wall 155 of the valve body member 15, the root portion 1573 extends along the axial direction of the main body portion 151, and the tip portion 1571 of the root portion 1573 forms a portion of the wall of the communication port 1561 of the second flow path.

The root portion 1573 extends along a direction that forms an included angle a with the axis of the main body portion 151. The angle that the included angle a forms with the axis of the main body portion 151 is (0, 90). <a≦90°である。 In some embodiments, the angle between the included angle a and the axis of the main body 151 is 90°, the root 1573 extends radially of the main body 151, and the tip of the root 1573 forms a part of the wall of the communication port 1561 of the second flow path 156, and in this case, the axial height of the fluid control device can be reduced.

[0061] Here, when the lug 157 has a non-linear structure, in the axial direction of the valve body member 15 passing through the axis, the connection position between the root portion 1573 and the peripheral wall 155 of the valve body member 15 is defined as a first point, the farthest end of the root portion 1573 from the peripheral wall 155 of the valve body member 15 is defined as a second point, and the angle between the first point and the second point and the included angle a and the axis of the main body portion 151 is defined as the angle between the line connecting the first point and the second point and the axis of the main body portion 151. When the angle between the included angle a and the axis of the main body portion 151 is 90 degrees, the plane on which the bottom end surface 1575 of the lug 157 is located is parallel to the axial direction of the valve body member 15 . In this case, the connection method between the protrusion 152 and the flow path connection portion 16 may refer to the connection method in any of the above-mentioned embodiments. For example, the protrusion 152 is welded and fixed to the flow path connection portion 16, or, if the flow path connection portion 16 has a branch portion, the branch portion and the protrusion 152 are welded or molded into an integral structure.

[0062] 22 to 25, the configuration of a fluid control device 60 is shown.
