Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to a multi-way valve suitable for energy storage systems. Background Technology

[0002] The valves used in existing energy storage systems are mostly small-flow valves. Different manufacturers have different requirements in terms of the number of pipe ports, interface type, and flow channel size, depending on their different thermal management situations.

[0003] In addition, different energy storage application scenarios have different requirements for internal leakage and different degrees of impact on heat exchange, and existing vehicle valves cannot be fine-tuned and adapted without changing the mold.

[0004] Therefore, existing valve products for energy storage systems suffer from poor versatility. Utility Model Content

[0005] This application provides a multi-way valve suitable for energy storage systems. It can flexibly switch between two-way, three-way, four-way, and five-way configurations by adjusting the number of sealing components and connecting pipes. In addition, the inner diameters of the multiple connecting pipes are partially or completely different, which can match different flow direction requirements, thereby effectively improving the versatility of the multi-way valve and greatly reducing the equipment usage cost.

[0006] This application provides a multi-way valve suitable for energy storage systems, including a valve body, a valve cover, and a ball valve. The ball valve is disposed within the valve cavity of the valve body. One side of the valve cover is sealed to the valve body, and the other side of the valve cover is used to connect to an actuator. The valve body has multiple ports that can communicate with the valve cavity. The valve body has a first connecting flange at each port. The multi-way valve suitable for energy storage systems also includes multiple connecting pipes and at least one sealing element. The number of connecting pipes and the sealing element is adapted to the number of ports. Both the connecting pipes and the sealing element have a second connecting flange that mates with the first connecting flange, so that the connecting pipes can be sealed to the ports, and the sealing element can block the ports. The multiple connecting pipes have different inner diameters.

[0007] In one possible implementation, the valve body has five ports evenly distributed on its surface, wherein the five ports are located on different surfaces of the valve body, and the sum of the number of the sealing element and the connecting pipe is five.

[0008] In one possible implementation, the connecting pipe is a sanitary clamp fitting, a bulge fitting, or a quick-connect fitting.

[0009] In one possible implementation, the connecting pipe has an annular sealing step along the circumferential direction of its inner wall at the pipe opening, and a sealing valve seat is fitted onto the annular sealing step. The connecting pipe is sealed to the port through the sealing valve seat, and the inner side of the sealing valve seat cooperates with the ball valve.

[0010] In one possible implementation, the annular sealing steps of the plurality of connecting pipes have different width dimensions to generate different sealing compressions on the sealing valve seat.

[0011] In one possible implementation, the sealing valve seat is a rubber sealing valve seat.

[0012] In one possible implementation, the connecting pipe is a straight arm structure or a bent pipe structure.

[0013] Beneficial effects: Compared with the prior art, the multi-way valve for energy storage systems provided in this application has multiple ports, as well as connecting pipes and sealing components that cooperate with the ports. Thus, the number of connecting pipes and sealing components can be flexibly adjusted to achieve flexible switching between different application forms such as two-way, three-way, four-way and even five-way, making it more versatile. In addition, since the inner diameters of the pipe openings of the multiple connecting pipes can be partially different (or partially the same) or completely different, the corresponding connecting pipes can be flexibly selected to adapt to different flow requirements, and it can basically be compatible with any size between φ10-φ50.

[0014] The connecting pipe is a separate component and can be designed into different pipe fitting forms according to interface requirements, making it more widely applicable;

[0015] The connecting pipe has an annular sealing step and a sealing valve seat on the inner wall at the pipe opening, which can achieve an effective sealing fit between the connecting pipe and the valve body. In addition, the annular sealing steps of multiple connecting pipes have different widths, which can flexibly select the connecting pipe with the corresponding width of the annular sealing step according to the different leakage requirements of customers, which can further increase the adaptability of the multi-way valve and make it more versatile.

[0016] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] 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.

[0025] refer to Figures 1 to 5This application provides a multi-way valve suitable for energy storage systems, including a valve body 10, a valve cover 20, and a ball valve 30. The ball valve 30 is disposed within the valve cavity 101 of the valve body 10. One side of the valve cover 20 is sealed to the valve body 10, while the other side of the valve cover 20 is used to connect to an actuator 40. This split design of the actuator 40 and the valve body 10 allows the multi-way valve to be matched with actuators 40 of different specifications. In addition, the valve body 10 has multiple ports 102 that can communicate with the valve cavity 101, and the valve body 10 has multiple ports 102 at the ends of the ports 102. A first connecting flange 11 is provided at port 102. The multi-way valve for energy storage system also includes multiple connecting pipes 50 and at least one sealing element 60. The number of connecting pipes 50 and the sealing element 60 is adapted to the number of ports 102. Both the connecting pipes 50 and the sealing element 60 are provided with a second connecting flange 51 that mates with the first connecting flange 11, so that the connecting pipes 50 can be sealed to the ports 102 and the sealing element 60 can seal the ports 102. The multiple connecting pipes 50 are provided with different inner diameters.

[0026] More specifically, the valve body 10 can have three, four, or even five ports, or more. The connecting pipes 50 can have two, three, or even four, or more connections. The sealing elements 60, such as sealing plates, can have one, two, or even three, or more connections. The key is the cooperation between the connecting pipes 50 and the sealing elements 60 and the ports 102. The connecting pipes 50 and ports 102 allow the multi-way valve to connect with external devices, while the sealing elements 60 seal the ports 102. This enables the multi-way valve to operate in two-way, three-way, four-way, or even five-way configurations, or more. The multi-way valve offers flexible switching between different application forms and strong versatility. Multiple connecting pipes 50 have different inner diameters, meaning that some connecting pipes 50 may have the same inner diameter, while only a few may have different inner diameters. Alternatively, all connecting pipes 50 may have different inner diameters; this is not a limitation. The key is that multiple connecting pipes 50 with different inner diameters can directly match products with different flow requirements. For example, it can be compatible with any size of pipe opening from φ10 to φ50, further enhancing the versatility of the multi-way valve and making it more convenient to use.

[0027] In one embodiment, combined Figure 5The valve body 10 has five ports 102 evenly distributed on its surface, located on different surfaces. The total number of sealing elements 60 and connecting pipes 50 is five. For example, in a two-way application, three of the five ports 102 are sealed by the sealing element 60, and the other two ports 102 are connected to two connecting pipes 50. Similarly, in a three-way application, two of the five ports 102 are sealed by the sealing element 60, and the other three ports 102 are connected to three connecting pipes 50. In a four-way application, one of the five ports 102 is sealed by the sealing element 60, and the other four ports 102 are connected to four connecting pipes 50. In a five-way application, the five ports 102 are connected to five connecting pipes 50 respectively, and the sealing element 60 is temporarily not used.

[0028] Furthermore, in two-way, three-way, and four-way applications, the port 102 of the connecting pipe 50 can be selected at any planar position, that is, it can realize straight connection or bent connection, or simultaneously realize straight connection and bent connection.

[0029] The connecting pipe 50 can be a straight arm structure or a bent pipe structure.

[0030] In one embodiment, since the connecting pipe 50 is a separate component, it is only necessary for the connecting pipe 50 to mate with the port 102, and for the first connecting flange 11 and the second connecting flange 51 to mate. The form of the connecting pipe 50 can be varied. For example, depending on the interface requirements, the connecting pipe 50 can be a sanitary clamp fitting, a bulge fitting, or a quick-connect fitting.

[0031] In one embodiment, the connecting pipe 50 has an annular sealing step 52 circumferentially arranged along the inner wall at the pipe opening, and a sealing valve seat 70 is fitted on the annular sealing step 52. The connecting pipe 50 is sealed to the port 102 through the sealing valve seat 70. At the same time, the inner side of the sealing valve seat 70 cooperates with the ball valve 30, thereby ensuring the sealing reliability between the connecting pipe 50 and the valve body 10 through the sealing valve seat 70.

[0032] More preferably, the annular sealing steps 52 of the multiple connecting pipes 50 have different widths to generate different sealing compressions on the sealing valve seat 70. This allows for fine-tuning or changing the compression of the sealing valve seat 70 using connecting pipes with annular sealing steps 52 of different widths to match different internal leakage requirements, further improving the adaptability and versatility of the multi-way valve. In the multiple connecting pipes 50, each connecting pipe 50 may have annular sealing steps 52 of different widths, or several connecting pipes 50 may have annular sealing steps 52 of the same width, with only a portion of the connecting pipes 50 having different widths. When different internal leakage requirements need to be matched, connecting pipes 50 with corresponding annular sealing steps 52 of the appropriate width can be directly installed, making it very convenient to use.

[0033] In one embodiment, the sealing valve seat 70 is a rubber sealing valve seat.

[0034] 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.

[0035] 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.
