Description

Technical Field

[0001] This utility model relates to the field of water valve equipment technology, and in particular to multi-way water valves. Background Technology

[0002] A multi-way water valve is a valve device that connects and controls multiple pipelines. It generally consists of a main body, a sealing ring and a column valve located inside the main body, and actuators and flanges located at both ends of the main body.

[0003] In the existing technology, multi-way water valves may have hot water flow channels and cold water flow channels flowing at the same time. If the two flow channels are adjacent, heat leakage is likely to occur, which will cause heat loss in the thermal management module.

[0004] In addition, the main housing contains both a column valve and a sealing ring. The sealing ring is located between the column valve and the main housing. When the column valve rotates, the sealing ring is prone to rotating with it, which leads to unstable internal leakage performance of the multi-way valve. Utility Model Content

[0005] This application provides a multi-way water valve that can effectively reduce heat loss between adjacent hot water and cold water channels, and can also limit the sealing ring in the rotation direction of the valve to ensure the leak-proof performance of the multi-way valve.

[0006] This application provides a multi-way water valve, including a valve body. An actuator and a flange are respectively connected to opposite ends of the valve body. A columnar valve core is fitted inside the valve body, and a sealing ring is provided between the columnar valve core and the valve body. The surface of the columnar valve core has multiple flow channel openings that cooperate with a water plate, allowing the columnar valve core to form various flow channels with the sealing ring and the valve body when rotating at different angles. Among the multiple flow channel openings are adjacently distributed hot and cold flow channels, with an air gap between the hot and cold flow channels. The opposite ends of the sealing ring are respectively provided with a first limiting structure, and the actuator and the flange are respectively provided with a second limiting structure that cooperates with the first limiting structure, thereby limiting the sealing ring when the columnar valve core rotates.

[0007] In one possible implementation, the hot runner and the cold runner are included in a plurality of flow channel ports in a vertically adjacent manner, and / or in a laterally adjacent manner, wherein the vertical direction refers to the axial direction of the columnar valve core.

[0008] In one possible implementation, the air gap is either a closed air gap or an open air gap.

[0009] In one possible implementation, the first limiting structure is located near the outer surface of the sealing ring, the first limiting structure is a groove structure, and the second limiting structure is a protrusion structure.

[0010] In one possible implementation, the first limiting structure is a trapezoidal groove structure. In the circumferential direction of the sealing ring, the opening size of the trapezoidal groove structure is larger than the bottom size of the trapezoidal groove structure, and the opening size is 1.05-1.15 times the bottom size.

[0011] In one possible implementation, the outer surface of the sealing ring is uniformly provided with multiple sets of sealing ribs along the circumferential direction and the longitudinal direction perpendicular to the circumferential direction. Each set of sealing ribs includes two parallel sealing strips. The sealing strips are trapezoidal strips, and the size of the end closer to the sealing ring is larger than the size of the end farther from the sealing ring. The first limiting structure is located between the two sealing strips of the same set of sealing ribs.

[0012] Beneficial effects: Compared with the prior art, the multi-way water valve provided in this application can reduce the thermal conductivity of the columnar valve core to a certain extent by setting an air gap between the adjacent hot flow channel and cold flow channel on the surface of the columnar valve core, thereby reducing the heat loss of the thermal management module. At the same time, a first limiting structure is set at the opposite ends of the sealing ring, and a second limiting structure is set on the actuator and flange respectively. The sealing ring can be limited when the columnar valve core rotates, preventing the sealing ring from rotating with it, thereby ensuring that the valve body is always in a sealed state, and thus ensuring the anti-internal leakage performance of the multi-way water valve.

[0013] The first limiting structure is a trapezoidal groove structure, and the opening size of the trapezoidal groove structure is 1.05 to 1.15 times the bottom size of the groove. On the one hand, it plays a guiding role in the assembly process, making it easy to install quickly and accurately. On the other hand, after the assembly is in place, it will form a relatively tight fit at the bottom of the groove and the position near the bottom of the groove. This can enhance the stability and firmness of the first limiting structure and the second limiting structure in limiting the sealing ring.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 4 This application provides a multi-way water valve, including a valve body 10, wherein an actuator 20 and a flange 30 are respectively connected to opposite ends of the valve body 10. A columnar valve core 11 is provided inside the valve body 10, and a sealing ring 12 is provided between the columnar valve core 11 and the valve body 10. When the columnar valve core 11 rotates, it will cooperate with the sealing ring 12 and the valve body 10 to form different flow channel forms when rotated to different angles, thereby meeting different mode requirements. The sealing ring 12 plays a sealing role to prevent internal leakage of the multi-way water valve.

[0023] The surface of the columnar valve core 11 is provided with a plurality of flow channel openings 101 that cooperate with the water plate, so that when the columnar valve core 11 rotates at different angles, it can cooperate with the sealing ring 12 and the valve body 10 to form various types of flow channels. This method of arranging flow channel openings 101 on the surface can prevent the flow channel from passing through the interior of the columnar valve core 11, thereby reducing the water flow resistance. In addition, the inner wall of the flow channel opening 101 adopts a smooth transition structure, which can further reduce the water flow resistance.

[0024] The plurality of flow channel ports 101 include adjacent hot flow channels 111 and cold flow channels 112, wherein an air gap 13 is provided between the hot flow channels 111 and the cold flow channels 112, thereby reducing the thermal conductivity and thus reducing the heat loss of the thermal management module. Such an air gap is not required between two adjacent hot flow channels 111 or two cold flow channels 112.

[0025] The sealing ring 12 is provided with a first limiting structure 121 at each of its opposite ends. Correspondingly, the actuator 10 and the flange 30 are provided with a second limiting structure 31 that cooperates with the first limiting structure 121. This limits the sealing ring 12 when the columnar valve core 11 rotates, thereby preventing the sealing ring 12 from rotating with the columnar valve core 11. This ensures that the valve body 10 is always in a sealed state, thus ensuring the anti-internal leakage performance of the multi-way water valve.

[0026] In one embodiment, the plurality of flow channel ports 101 include the hot flow channel 111 and the cold flow channel 112 distributed vertically adjacent to each other, and / or the hot flow channel 111 and the cold flow channel 112 distributed laterally adjacent to each other, wherein the vertical direction refers to the axial direction of the columnar valve core 11.

[0027] In one embodiment, the air gap 13 is either a closed air gap or an open air gap. As a closed air gap, it contains air, which can provide relatively better heat insulation and a slower heat transfer rate. As an open air gap, the antifreeze in the valve body 10 will enter the air gap 13, and the heat insulation effect will be relatively worse than that of the closed structure, but it can still provide heat insulation.

[0028] In one embodiment, the first limiting structure 121 is located near the outer surface of the sealing ring 12. The first limiting structure 121 is a groove structure, and correspondingly, the second limiting structure 31 is a protrusion structure that cooperates with the groove structure.

[0029] More preferably, the first limiting structure 121 is a trapezoidal groove structure. Furthermore, in the circumferential direction of the sealing ring 12, the opening size of the trapezoidal groove structure is larger than the bottom size of the groove, and the opening size is 1.05-1.15 times the bottom size. In this way, compared to a vertically extending square groove structure, the trapezoidal groove can play a guiding and limiting role during assembly, facilitating the quick and accurate installation of the multi-way water valve. At the same time, compared to a semi-circular or arc-shaped groove, the trapezoidal groove, combined with the protruding structure, can better fulfill the limiting role. Especially as the assembly is complete, the tightness of the fit at the bottom of the groove and near the bottom will be better, effectively improving the stability and firmness of the first limiting structure 121 and the second limiting structure 31 in limiting the sealing ring 12.

[0030] Considering that the slotted design may have a certain negative impact on the structural strength of the sealing ring 12, in one embodiment, the outer surface of the sealing ring 12 is uniformly provided with multiple sets of sealing ribs 122 along the circumferential direction and the longitudinal direction perpendicular to the circumferential direction. Each set of sealing ribs 122 includes two parallel sealing strips. The sealing strips are trapezoidal strips, and the size of the end closer to the sealing ring 12 is larger than the size of the end farther away from the sealing ring 12. At the same time, the first limiting structure 121 is located between the two sealing strips of the same set of sealing ribs 122. In this way, the sealing strips on both sides can greatly offset the influence of the first limiting structure 121 on the structural strength of the sealing ring 12, making the overall structure of the multi-way water valve more stable.

[0031] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
