Description

Technical Field

[0001] This utility model relates to the field of water valves, specifically to a proportional four-way valve. Background Technology

[0002] In the thermal management system of new energy vehicles, multiple circulation loops are designed. Based on the principle of vehicle thermal management, multiple water valves are needed to achieve water circuit connection and blockage under various operating conditions.

[0003] Currently, in order to improve the driving range of new energy vehicles, the requirements for thermal management design are becoming increasingly stringent, and the number of thermal management components is also increasing. In existing models, these components are distributed, occupying a significant amount of space. This distributed distribution necessitates the use of numerous cooling and air conditioning pipes to connect the components. The problems arising from these extensive cooling and air conditioning pipes include: increased vehicle cost, reduced space utilization, decreased thermal management efficiency, and increased system energy consumption.

[0004] In currently available car models, it is common to see a combination of multiple on / off valves. In order to improve the driving range, new energy vehicles have increasingly more requirements for vehicle thermal management design. From the perspectives of cost saving, weight reduction, and space utilization, it is more important to integrate multiple on / off valves into a smaller number of multifunctional water valves.

[0005] In the existing technology, there are many four-way valves, but it is difficult to combine proportional regulation and ordinary flow channels in series. In order to meet the requirements of cost saving, lightweighting and layout space, a simple and practical structure is needed. Designing a simple and practical structure to overcome the on / off problem is also a technical challenge for most four-way valves.

[0006] In view of this, it is necessary to improve the existing multi-way valves to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a proportional four-way valve to solve the problems of existing proportional four-way valves having a large volume and difficulty in achieving proportional connection.

[0008] To achieve the above objectives, the proportional four-way valve of this utility model includes a valve core and a valve body for housing the valve core. The valve core is rotatably disposed relative to the valve body. The valve core is provided with a transverse flow channel and a longitudinal flow channel. The transverse flow channel extends in the circumferential direction, and the longitudinal flow channel extends axially. The valve body is provided with three transverse flow channel openings and one longitudinal flow channel opening. The three transverse flow channel openings are arranged sequentially in the circumferential direction, and the longitudinal flow channel opening is arranged adjacent to one transverse flow channel opening in the axial direction. The transverse flow channel is used to connect two transverse flow channel openings, and the longitudinal flow channel is used to connect the longitudinal flow channel and one transverse flow channel.

[0009] As a further improvement of this utility model, a transverse flow channel is provided at the middle of the adjacent longitudinal flow channel.

[0010] As a further improvement of this utility model, the transverse flow channel and the longitudinal flow channel are arranged on opposite sides of the valve core.

[0011] As a further improvement of this utility model, the length of the transverse flow channel is less than or equal to the distance between the farthest ends of two adjacent transverse flow channel openings.

[0012] As a further improvement of this utility model, the valve body includes a base plate and a side wall extending from the base plate toward one side, the transverse flow channel and the longitudinal flow channel are disposed on the side wall, and the valve body has an opening on the side away from the base plate.

[0013] As a further improvement of this utility model, a positioning post is provided protruding on the side of the base plate facing the opening, and a positioning groove is provided on the valve core to match the positioning post. The positioning post and the valve core are coaxially arranged.

[0014] As a further improvement of this utility model, the proportional four-way valve also includes a valve cover for blocking the opening, the valve cover having a clearance hole, and the valve core including a body and a rotating shaft extending from the body through the clearance hole.

[0015] As a further improvement of this utility model, the proportional four-way valve further includes a first sealing ring arranged around the rotating shaft. The first sealing ring is located axially between the valve cover and the body. A first protrusion is provided on the valve cover facing the body, and the first protrusion abuts against the first sealing ring axially.

[0016] As a further improvement of this utility model, the proportional four-way valve also includes a second sealing ring. The side of the body facing the valve cover is recessed inward and has a receiving groove. The second sealing ring is arranged radially around the outside of the first sealing ring and is received in the first receiving groove. The valve cover has a second protrusion extending in the direction of the body and abutting against the second sealing ring in the axial direction.

[0017] As a further improvement of this utility model, the proportional four-way valve also includes a sealing gasket fixed to the valve core, the sealing gasket being radially pressed between the valve core and the valve body.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1 to 5 As shown, the proportional four-way valve 100 of this utility model includes a valve core 1, a valve body 2 for housing the valve core 1, a valve cover 3, a first sealing ring 4, a second sealing ring 5, and a sealing gasket 6.

[0028] The valve core 1 is rotatably disposed relative to the valve body 2. The valve core 1 includes a body 11 and a rotating shaft 12 extending from the body 11 through the valve cover 3.

[0029] In this embodiment, the end of the rotating shaft 12 away from the body 11 is provided with a spline for connection and cooperation with the actuator.

[0030] The valve core 1 is provided with a transverse flow channel 13 and a longitudinal flow channel 14. The transverse flow channel 13 extends in the circumferential direction, and the longitudinal flow channel 14 extends axially.

[0031] In this embodiment, the two flow channels cannot operate simultaneously. Therefore, the transverse flow channel 13 and the longitudinal flow channel 14 are located on opposite sides of the valve core 1 to avoid mutual interference. In this embodiment, the opposite sides of the valve core 1 do not necessarily mean that they must be directly opposite each other; as long as the transverse flow channel 13 and the longitudinal flow channel 14 are staggered without affecting each other's flow, it is acceptable.

[0032] The valve body 2 is provided with three transverse flow ports 21 and one longitudinal flow port 22. The three transverse flow ports 21 are arranged in sequence along the circumferential direction. The longitudinal flow port 22 is arranged adjacent to one transverse flow port 21 along the axial direction. The transverse flow channel 13 is used to connect two transverse flow ports 21. The longitudinal flow channel 14 is used to connect the longitudinal flow channel 14 and one transverse flow channel 13.

[0033] Three transverse flow channels 21 are defined as transverse flow channel 1 211, transverse flow channel 212 and transverse flow channel 213 in the circumferential direction.

[0034] In this embodiment, a transverse flow channel 21 is provided adjacent to the middle of the longitudinal flow channel 22, that is, the longitudinal flow channel 22 is adjacent to the second transverse flow channel 212.

[0035] In this embodiment, the proportional four-way valve 100 has three operating modes:

[0036] Operating mode 1: The transverse flow channel 13 is connected to the first transverse flow channel port 211 and the second transverse flow channel port 212.

[0037] Working mode 2: The transverse flow channel 13 is connected to the second transverse flow channel port 212 and the third transverse flow channel port 213.

[0038] Working mode 3: The longitudinal flow channel 14 is connected to the second transverse flow channel port 212 and the longitudinal flow channel port 22.

[0039] In this embodiment, in operating modes one and two, the transverse flow channel 13 is fully connected to the first transverse flow channel port 211 and the third flow channel port. However, by adjusting the angle of the valve core 1, the transverse flow channel 13 is proportionally connected to the second transverse flow channel port 212. This proportional connection means that only a portion of the transverse flow channel 13 is connected to the second transverse flow channel port 212 circumferentially, while another portion is blocked by the valve core 1. Flow control is achieved by adjusting the proportion of the blocked area.

[0040] This utility model's proportional four-way valve 100, within the same volume, can achieve proportional adjustment while switching modes. On the one hand, it can integrate up to three flow channels into a water valve; on the other hand, it supports proportional adjustment of up to two flow channels. Therefore, when applied to thermal management modules, it can reduce the amount of cooling and air conditioning piping, thereby reducing the volume and heat loss of the thermal management system.

[0041] In this embodiment, the length of the transverse flow channel 13 is limited to be less than or equal to the distance between the farthest ends of two adjacent transverse flow channel openings 21. This configuration avoids the transverse flow channel 13 connecting to three transverse flow channel openings 21. However, in some embodiments, the transverse flow channel 13 is made wider, which can increase the number of times the transverse flow channel 13 connects to three transverse flow channel openings 21.

[0042] The valve body 2 includes a base plate 23 and a side wall 24 extending from the base plate 23 toward one side. The transverse flow channel 21 and the longitudinal flow channel 22 are disposed on the side wall 24. The valve body 2 has an opening on the side away from the base plate 23.

[0043] The valve cover 3 is used to cover the opening, and the valve cover 3 is provided with a relief hole, through which the rotating shaft 12 passes.

[0044] The base plate 23 has a protruding positioning post 231 facing the opening, and the valve core 1 has a recessed positioning groove for matching the positioning post 231. The positioning post 231 is coaxially arranged with the valve core 1. The insertion and engagement of the positioning post 231 with the positioning groove can improve the stability of the valve core 1's operation.

[0045] The sealing gasket 6 is fixed to the valve core 1, and the sealing gasket 6 abuts radially between the valve core 1 and the valve body 2. The sealing gasket 6 has notches corresponding to the transverse flow channel 13 and the longitudinal flow channel 14. In addition, the sealing gasket 6 tightly covers the valve core 1 axially. In this embodiment, the sealing gasket 6 achieves full coverage of the valve core 1. The design of the sealing gasket 6 covering the valve core 1 increases the filling of the sealing space inside the proportional four-way valve 100. On the one hand, the valve core 1 is subjected to uniform force, reducing torque and the risk of sealing gasket 6 jamming. On the other hand, the closed space reduces the false detection of external leakage in production, thus optimizing the effect.

[0046] The main body 11 is provided with a mounting slot 112 for mounting the sealing gasket 6.

[0047] The first sealing ring 4 is disposed around the rotating shaft 12 and is located axially between the valve cover 3 and the body 11. A first protrusion 31 is provided on the valve cover 3 protruding towards the body 11, and the first protrusion 31 abuts against the first sealing ring 4 axially. In this embodiment, by providing the first protrusion 31, the first sealing ring 4 can be pressed tightly to prevent external leakage due to the first sealing ring 4 not being placed horizontally.

[0048] The body 11 has an inwardly recessed receiving groove 111 on the side facing the valve cover 3. The second sealing ring 5 is radially arranged around the first sealing ring 4 and received within the receiving groove 111. The valve cover 3 has a second protrusion 32 protruding towards the body 11, and the second protrusion 32 abuts against the second sealing ring 5 axially. The second sealing ring 5 is made of PTFE (polytetrafluoroethylene), which has a self-lubricating effect to reduce torque. The receiving groove 111 radially limits the position of the second sealing ring 5.

[0049] The proportional four-way valve 100 of this utility model, by setting a transverse flow channel 13 and a longitudinal flow channel 14, can achieve proportional adjustment while switching modes, realize the integration of at least three flow channels, optimize the design and reduce the size.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
