Description

Technical Field

[0001] This utility model relates to the field of refrigeration accessories, and in particular to an air conditioning valve and an air conditioner having the same. Background Technology

[0002] As a key component of air conditioning systems, the shut-off valve is mainly used to control the opening and closing of the refrigerant flow path between the indoor and outdoor units. In traditional designs, the shut-off valve typically needs to connect to the outdoor unit's flow path, the connecting pipe between the indoor and outdoor units, and may also have interfaces for refrigerant charging or system vacuuming. This results in a relatively complex structure for the shut-off valve, with numerous connecting pipes, a large overall footprint, and cumbersome installation and connection.

[0003] Therefore, it is necessary to improve the structure of the air conditioning shut-off valve to simplify the connection structure. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0066] The following is for reference. Figures 1-13 Description of an air conditioning valve 100 according to a first aspect embodiment of the present invention.

[0067] like Figures 1-3 As shown, the air conditioning valve 100 includes: valve island 10 and shut-off valve core 30.

[0068] Specifically, the valve island 10 is provided with an intermediate channel 131, a first channel 132, and a second channel 1331. The first channel 132 is connected to the intermediate channel 131 through a first port 1321, and the second channel 1331 is connected to the intermediate channel 131 through a second port 1333.

[0069] It should be noted that the number of intermediate channels 131, first channels 132, and second channels 1331 within the air conditioning valve 100 is unlimited. Here, each intermediate channel 131 corresponds to one first channel 132 and one second channel 1331, and each intermediate channel 131 contains a shut-off valve core 30. Combined with... Figure 1 and Figure 2 In this embodiment, the air conditioning valve 100 is provided with two intermediate channels 131, and the two intermediate channels 131 are located at different positions on the valve island 10.

[0070] It should be noted that the relative positions between the first channel 132 and the second channel 1331 are not limited to a specific form. Specifically, in conjunction with... Figure 3 As shown, the first channel 132 and the second channel 1331 can be arranged perpendicularly to each other; or, please combine... Figure 4 and Figure 5 As shown, the first channel 132 and the second channel 1331 can also be configured with a certain angle according to the layout requirements to adapt to various connection needs.

[0071] The valve island 10 is also provided with an operating port 135 that connects to the intermediate channel 131. At least a portion of the shut-off valve core 30 is movably disposed within the intermediate channel 131.

[0072] Specifically, the valve island 10 has an operating port 135 that communicates with the outside. Here, the operating port 135 is used to allow external tools to directly operate the operating end 31 of the shut-off valve core 30.

[0073] The shut-off valve core 30 is movably disposed within the intermediate channel 131 of the valve island 10 and can be switched to a shut-off position or an open position. In some alternative embodiments, the shut-off valve core 30 may be rotary, screw-in, or sliding.

[0074] For example, the movable engagement between the shut-off valve core 30 and the intermediate channel 131 can be a plug structure. For instance, the shut-off valve core 30 can rotatably enter or exit the intermediate channel 131; or, the shut-off valve core 30 can be a spherical valve core, which moves within the intermediate channel 131 by rotating it. The engagement between the shut-off valve core 30 and the intermediate channel 131 in this application can also adopt the valve core and flow channel engagement method in the prior art, to achieve flexible control of the fluid flow state.

[0075] The shut-off valve core 30 is movably disposed within the intermediate channel 131 and can switch between a shut-off position and an open position. The state of the shut-off valve core 30 in the shut-off position is determined by... Figures 6 to 9 As shown, the state of the shut-off valve core 30 in the open position is combined with... Figures 10-13 .

[0076] The shut-off valve core 30 blocks at least one of the first port 1321 and the second port 1333. In the open position, the shut-off valve core 30 either avoids or opens the first port 1321 and the second port 1333, allowing fluid to flow between the channels.

[0077] Specifically, combined Figure 3 When the shut-off valve core 30 is in the shut-off position, it can block the first port 1321 through its end face to block the fluid communication between the first channel 132 and the intermediate channel 131; or block the second port 1333 to cut off the flow path between the second channel 1331 and the intermediate channel 131 to prevent fluid leakage or backflow.

[0078] In some embodiments, combined with Figure 4 When the shut-off valve core 30 is in the shut-off position, it can simultaneously block the first port 1321 and the second port 1333. At this time, the shut-off valve core 30 has two independent sealing surfaces, corresponding to the first channel 132 and the second channel 1331 respectively, thereby achieving simultaneous isolation of the two channels and improving the sealing performance of the shut-off valve core 30.

[0079] In addition, in some technical solutions, the combination of Figure 5 The shut-off valve core 30 has an internal channel, one end of which always faces the first port 1321. When the shut-off valve core 30 is in a certain position, the other end of the internal channel is blocked by the inner wall of the intermediate channel 131, thereby blocking the flow of fluid; when the shut-off valve core 30 is rotated to another position, the other end of the internal channel is aligned with the second port 1333, so that the first port 1321 and the second port 1333 are connected through the internal channel, realizing the switching of the flow path.

[0080] In other embodiments, the shut-off valve core 30 moves or rotates to avoid the first port 1321 and the second port 1333, so that the two channels are naturally connected through the intermediate channel 131, thereby achieving smooth fluid flow.

[0081] Combination Figures 3-5 It can be seen that the relative positional relationship between the first channel 132 and the second channel 1331 is not limited. They can be perpendicular to each other, or they can be set to a certain angle according to actual needs to adapt to different pipeline layouts and installation conditions. In the structure of the shut-off valve core 30 with two sealing surfaces, the angle between the first channel 132 and the second channel 1331 can be matched with the sealing surfaces to achieve a good sealing fit.

[0082] The shut-off valve core 30 includes an operating end 31 located at the operating port 135, allowing external components to engage with the operating end 31 via the operating port 135 to move the shut-off valve core 30. For example, a user can change the position of the shut-off valve core 30 through simple mechanical operations (such as rotation, push-pull, etc.).

[0083] In this application, the valve island 10 and the shut-off valve core 30 constitute the shut-off valve of the air conditioner 1000. This arrangement integrates the function of the original external shut-off valve into the air conditioning valve 100, effectively reducing the external pipeline connection and installation space, improving the overall structural compactness, and also helping to optimize the internal space layout of the air conditioner 1000, thereby improving system integration and assembly efficiency.

[0084] At the same time, the internally integrated structure also improves the connection strength between channels, avoiding structural weakness caused by too many external connections.

[0085] In addition, the simplified pipework structure improves assembly efficiency and further enhances the reliability of the Air Conditioner 1000.

[0086] In summary, the air conditioning valve 100 provided by this utility model has a reasonable structure, high integration, simple pipeline structure, and high assembly efficiency.

[0087] According to some embodiments of the present invention, the air conditioning valve 100 has an operating port 135 and a first port 1321 arranged along a first direction. The shut-off valve core 30 is movable along the first direction. When the shut-off valve core 30 is in the shut-off position, it blocks the first port 1321 to cut off the connection between the first channel 132 and the second channel 1331. When the shut-off valve core 30 is in the open position, it moves away from the first port 1321 so that the first channel 132 and the second channel 1331 are connected through the intermediate channel 131.

[0088] First, the operating port 135 and the first port 1321 are arranged in the same direction, so that the operating path of the shut-off valve core 30 is consistent with the opening and closing direction of the fluid channel, which facilitates the operation of external operating components (such as knobs, wrenches, etc.) to rotate the shut-off valve core 30.

[0089] Furthermore, since the shut-off valve core 30 moves linearly along the first direction, its movement trajectory is stable and not easily deviated, which helps to improve the alignment accuracy of the sealing position, thereby improving the sealing performance and operational reliability of the valve.

[0090] Specifically, in combination Figures 1-2 , Figures 6-7 and Figure 9 When the intermediate channel and the shut-off valve core 30 are configured as a high-pressure shut-off valve 101, the first channel 132 is used to connect the condenser outlet of the outdoor unit of the air conditioner, and the second channel 1331 is used to connect the internal and external pipes to connect the condenser outlet to the evaporator inlet of the outdoor unit of the air conditioner, so as to realize the control of the refrigerant delivery from the outdoor unit 500 to the indoor unit 400.

[0091] Combination Figures 1-2 , Figures 6-7 and Figure 8When the intermediate channel and the shut-off valve core 30 are configured as a low-pressure shut-off valve 102, the first channel 132 is used to connect the compressor suction port or the gas-liquid separator inlet of the outdoor unit, and the second channel 1331 is used to connect the internal and external pipes to connect the compressor suction port to the evaporator outlet of the indoor unit, so as to realize the opening and closing control of the return airflow path.

[0092] Furthermore, the air conditioning valve 100 includes two intermediate channels, one of which serves as part of the valve body of the high-pressure shut-off valve 101, and the other as part of the valve body of the low-pressure shut-off valve 102. Integrating the high-pressure shut-off valve 101 and the low-pressure shut-off valve 102 into the same air conditioning valve 100 makes the functions of the air conditioning valve 100 more integrated, facilitates centralized control and maintenance, and at the same time reduces external piping connections, simplifies the connection structure, and improves structural stability.

[0093] Specifically, the valve island 10 has an operating channel 134 connecting the intermediate channel 131 and the operating port 135, and the inner wall of the operating channel 134 has an internal thread. The outer wall of the shut-off valve core 30 has an external thread that mates with the internal thread, and the shut-off valve core 30 can move spirally in the first direction.

[0094] In the above technical solution, the spiral movement of the shut-off valve core 30 is achieved through threaded connection, which enables precise control of the valve core position, thereby improving the accuracy of blocking or opening the port.

[0095] The screw drive structure also has good self-locking properties. After the valve core 30 is adjusted, its position is not easily displaced, which helps to maintain a stable state and improve the controllability of the valve.

[0096] Specifically, the operating end 31 can be a non-circular countersunk hole or a non-circular boss.

[0097] Here, the non-circular countersunk hole is a groove that is not circular in shape (such as hexagonal, square, straight, plum blossom-shaped, etc.) for external operating tools (such as wrenches, screwdrivers, special screwdrivers) to be inserted for rotation.

[0098] Non-circular bosses refer to operating end 31 as non-circular protrusions (such as hexagonal pillars, square pillars, etc.), which can be clamped by external drive components and rotated.

[0099] Both of the above structures, serving as the operating end 31, can achieve reliable torque transmission, prevent slippage, and further improve the reliable control of the shut-off valve core 30.

[0100] Alternatively, the internal threads are distributed on the inner wall of the operating channel 134 and partially on the inner wall of the intermediate channel 131, extending to the first port 1321. In the first direction, the length of the external threads is greater than the length of the intermediate channel 131, so that a portion of the shut-off valve core 30 is always fitted within the operating channel 134.

[0101] Because the length of the external thread is greater than the length of the intermediate channel 131, a portion of the shut-off valve core 30 is always located within the operating channel 134, preventing it from completely entering the intermediate channel 131 and then leaving the operating channel 134, thereby ensuring the sealing effect.

[0102] Furthermore, due to the length limitation of the external thread, the shut-off valve core 30 will not shift or tilt due to excessive insertion. Moreover, the longer external thread can effectively prevent the shut-off valve core 30 from slipping out or accidentally entering the intermediate channel 131 due to excessive rotation during operation, thus improving safety and reliability during use.

[0103] Alternatively, a limiting ring can be provided at the connection between the intermediate channel 131 and the operating channel 134. When the shut-off valve core 30 moves to its limit position, it engages with the limiting ring to prevent the shut-off valve core 30 from completely entering the intermediate channel 131, while also improving the positioning accuracy of the sealing surface.

[0104] In some embodiments, such as Figure 3 As shown, the diameter of the first port 1321 is smaller than the diameter of the shut-off valve core 30, and an annular contact line is formed between the shut-off valve core 30 and the inner wall of the first port 1321 at the shut-off position.

[0105] At this time, the outer edge of the shut-off valve core 30 is fully fitted against the inner wall of the first port 1321, forming a complete annular contact line. This annular contact line can achieve a hard seal between the shut-off valve core 30 and the first port 1321. When the shut-off valve core 30 and the inner wall of the first port 1321 are metal parts, the annular contact line can achieve a hard seal between metal parts.

[0106] Optional, combined Figures 6-13 The diameter of the operating port 135 is smaller than the diameter of the operating channel 134, and an annular stepped surface 1341 is formed at the connection between the operating port 135 and the operating channel 134. In the open position, the shut-off valve core 30 abuts against the annular stepped surface 1341.

[0107] Specifically, when the shut-off valve core 30 moves to the open position along the first direction, one end face abuts against the annular stepped surface 1341 and forms a full-circle contact with the annular stepped surface 1341, thereby achieving a hard seal structure. In the open position, it also prevents fluid leakage from the operating port 135, improving the overall sealing performance.

[0108] Furthermore, by setting an annular stepped surface 1341 between the operation channel 134 and the operation port 135, there is no need to set additional seals or sealing structures, which simplifies the structure and improves the integration of the air conditioning valve 100.

[0109] In addition, the annular stepped surface 1341 also has a limiting function for the shut-off valve core 30, preventing the shut-off valve core 30 from extending excessively or deviating during operation, thereby improving the stability and controllability of operation.

[0110] According to some alternative embodiments, such as Figures 8-9 and Figures 12-13 As shown, the valve island 10 also includes a first connecting pipe 133, which is connected to the first valve body and communicates with the second channel 1331. The end of the first connecting pipe 133 away from the middle channel 131 forms a first interface 1332, which is used to connect the internal and external unit connecting pipes.

[0111] Combination Figure 12 One end of the second channel 1331 is connected to the middle channel 131, and the other end extends to the end of the first connecting pipe 133, where a first interface 1332 is formed. The first interface 1332 is used to connect the indoor and outdoor unit connecting pipes in the air conditioning system so that refrigerant can flow between the first valve body 13 and the external pipeline.

[0112] The intermediate channel 131 and the first connecting pipe 133 are located on both sides of the mounting plate 11. This makes full use of the space on both sides of the mounting plate 11, avoids component accumulation, and improves space utilization. It also helps to improve the flexibility of the piping arrangement in the air conditioning valve 100.

[0113] In the structure of the air conditioning valve 100, a first sealing member 51 for opening and closing the first interface 1332 is also provided.

[0114] After the first sealing element 51 seals the first interface 1332, it prevents refrigerant from leaking from the first interface 1332 or external impurities from entering through the first interface 1332. When in the open position, the first interface 1332 is open, allowing refrigerant to flow into or out of the second channel 1331 through the first interface 1332.

[0115] This design gives the air conditioning valve 100 a certain degree of flexibility and safety during installation and maintenance.

[0116] For example, when no external piping is connected, sealing the first interface 1332 with the first sealing element 51 can effectively prevent refrigerant leakage and prevent dust, impurities, etc. from entering the valve island 10, ensuring the stability of the air conditioner 1000. When it is necessary to connect the indoor and outdoor unit piping, the first sealing element 51 can be opened to achieve quick connection with the external piping. The operation is simple and highly adaptable.

[0117] Optionally, the first sealing element 51 may be a threaded connection, a rotating cap type or a snap-fit ​​type, etc., to achieve reliable opening and closing control of the first interface 1332.

[0118] Alternatively, the first connecting pipe 133 can be integrally formed into the structure of the valve island 10. This improves structural strength and sealing performance, reduces the risk of leakage, and reduces the number of assembly parts.

[0119] According to some optional embodiments of the present application, the air conditioning valve 100 includes a valve island 10 comprising a mounting plate 11 and a first valve body 13, the first valve body 13 being mounted on the mounting plate 11.

[0120] By setting the first valve body 13 on the mounting plate 11 to form the valve island 10, and then fixing the mounting plate 11, the air conditioning valve 100 is more convenient to connect and its internal structure is more stable.

[0121] Meanwhile, mounting plate 11 can also provide a mounting base for other parts (such as four-way valves, expansion valves, connecting pipe ports, etc.), making it easy to integrate multiple functions.

[0122] Optionally, the mounting plate 11 is provided with a mounting portion for fixing, so as to install the first valve body 13 and other parts. Further optionally, the mounting portion may include mounting holes, mounting rails or other connecting and fixing structures.

[0123] In some technical solutions, the first valve body 13 and the valve island 10 can be formed in one step. Alternatively, the first valve body 13 and the valve island 10 can be integrally cast. Of course, this utility model is not limited to this; the first valve body 13 can also be formed after the valve island 10 has been formed, in which case the first valve body 13 and the valve island 10 can be formed after two processing steps. It is understood that regardless of the specific processing order of the first valve body 13 and the valve island 10, as long as the first valve body 13 and the valve island 10 are set together, it is acceptable.

[0124] In some technical solutions, combined Figure 12 and Figure 13 The valve island 10 also includes a second valve body 15 disposed on the first valve body 13. The second valve body 15 is provided with a filling channel 151. One end of the filling channel 151 is connected to the intermediate channel 131, and the other end forms a second interface 1511.

[0125] Here, the second valve body 15 is directly installed on the first valve body 13, and fluid connection is achieved through the internal filling channel 151, further reducing the number of external pipelines.

[0126] Meanwhile, the air conditioning valve 100 has been upgraded with the functions of charging and discharging refrigerant, further improving its integration.

[0127] In some alternative embodiments, the second valve body 15 is integrally formed into the structure of the first valve body 13. This results in a compact structure, high production efficiency, and better sealing performance; alternatively, the second valve body 15 is fixedly connected to the first valve body 13. This facilitates assembly and maintenance while ensuring the robustness and stability of the connection.

[0128] like Figures 8-9 , Figures 12-13 As shown, the air valve 100 also includes a valve core assembly 60 disposed in the filling channel 151.

[0129] It is known that the valve core assembly 60 is a common component that can automatically control the opening and closing of the channel without manual intervention.

[0130] By placing the valve core assembly 60 within the charging channel 151, refrigerant leakage can be effectively prevented when not charging. Due to its self-locking characteristic, the valve core assembly 60 remains closed when not connected to external equipment, ensuring the sealing and safety of the internal system of the air conditioner 1000 and avoiding potential leakage problems due to accidents. When the operator connects the charging equipment to the second interface 1511, the valve core assembly 60 automatically opens, thereby opening the charging channel 151 to facilitate refrigerant charging operations, improving operational convenience and work efficiency.

[0131] Furthermore, the second valve body 15 is located on the side of the first valve body 13 away from the mounting plate 11.

[0132] The second valve body 15 is stacked on top of the first valve body 13, making full use of the vertical space of the valve island 10 and avoiding lateral expansion on the plane of the mounting plate 11. This helps to achieve a compact overall structure of the valve island 10.

[0133] At the same time, it reduces the number of mounting points and stress points on the mounting plate 11. This helps to reduce the structural burden on the mounting plate 11, avoid local stress concentration, and improve the overall structural stability.

[0134] Furthermore, the filling channel 151 of the second valve body 15 can be directly connected to the intermediate channel 131 inside the first valve body 13, which facilitates the integration of internal fluid channels and reduces external pipeline connections.

[0135] Optionally, the second valve body 15 and the first valve body 13 are integrally formed, or the second valve body 15 is fixedly connected to the first valve body 13.

[0136] Here, integrating the second valve body 15 with the first valve body 13 reduces the number of external connection pipes, making the overall structure of the air conditioning valve 100 simpler and easier to assemble. It also reduces the risk of leakage and improves the stability and reliability of the system.

[0137] The second valve body 15 and the first valve body 13 can be integrally formed. For example, the second valve body 15 and the first valve body 13 can be integrally cast. Of course, this utility model is not limited to this; the second valve body 15 can also be manufactured after the first valve body 13 has been formed. In this case, the first valve body 13 and the second valve body 15 can be formed after two processing steps. It is understood that regardless of the specific processing order of the first valve body 13 and the second valve body 15, as long as the first valve body 13 and the second valve body 15 are set together, it is acceptable.

[0138] The second valve body 15 and the first valve body 13 can be connected by any one or more of the following methods: welding, flange connection, compression fitting, or adhesive bonding.

[0139] The air conditioning valve 100 also includes a second sealing element 52 for opening and closing the second interface 1511.

[0140] Specifically, when the second sealing component 52 seals the second interface 1511, it can prevent refrigerant leakage; when the second sealing component 52 opens the second interface 1511, it allows refrigerant to be charged into or recovered into the system through the second interface 1511.

[0141] In practical applications, operators can connect to external charging equipment via the second interface 1511 and perform refrigerant charging, recovery, or testing operations in the refrigerant circulation loop of the air conditioning system through the charging channel 151. This configuration integrates the charging function into the air conditioning valve 100, eliminating the need for a separate charging port or connecting pipe, improving the structural stability of the charging channel 151, simplifying the structure, and increasing assembly efficiency.

[0142] The second sealing element 52 is a cover and is threadedly connected to the second valve body 15, which facilitates disassembly and maintenance, improving maintainability and ease of operation. At the same time, the threaded connection ensures the stability of the second sealing element 52 and effectively prevents media leakage.

[0143] Furthermore, the operating port 135 and the first port 1321 are arranged along the first direction, and the shut-off valve core 30 is movable along the first direction. The intermediate channel 131 and the second channel 1331 are extended along the second direction, which is perpendicular to the first direction, and the filling channel 151 is always connected to the second channel 1331 through the intermediate channel 131.

[0144] The operating port 135 and the first port 1321 are arranged along the first direction, and the shut-off valve core 30 is movable along the first direction, which helps to simplify the internal structure of the valve body, making the operation more stable and the action response faster.

[0145] Meanwhile, the intermediate channel 131 and the second channel 1331 extend along a second direction, which is perpendicular to the first direction, simplifying the fluid path, reducing flow resistance, and improving flow efficiency. The filling channel 151 is always connected to the second channel 1331 through the intermediate channel 131, ensuring that the filling function is always available at different positions of the shut-off valve core 30.

[0146] In some specific examples, there are at least two first valve bodies 13, each equipped with a shut-off valve core 30. A portion of the first valve bodies 13 and the corresponding shut-off valve core 30 constitute the high-pressure shut-off valve 101 of the air conditioner 1000, and another portion of the first valve bodies 13 and the corresponding shut-off valve core 30 constitute the low-pressure shut-off valve 102 of the air conditioner 1000. Multiple first valve bodies 13 are arranged at intervals on the valve island 10.

[0147] Combination Figures 1-2 , Figure 14 and Figure 15 As shown, the first channel 132 of the high-pressure shut-off valve 101 is connected to the throttling element of the outdoor unit 500, and the low-pressure shut-off valve 102 is connected to the suction port of the compressor 200 in the outdoor unit 500. The two shut-off valve cores 30 control the opening and closing of their respective first ports 1321. During vacuuming, the two shut-off valve cores 30 close their respective first ports 1321. At this time, a vacuum machine connected to the charging channel 151 of at least one of the high-pressure shut-off valve 101 and the low-pressure shut-off valve 102 is used to vacuum the indoor unit 400 side, creating a negative pressure on the indoor unit 400 side. During refrigerant charging, the first channel 132 is opened through the shut-off valve core 30, and refrigerant is then charged into the air conditioner 1000 through the charging channel 151, enabling system debugging and maintenance.

[0148] Further optional, combined Figures 1-2 , Figures 6-13 As shown, the valve island 10 includes two first valve bodies 13, each of which is equipped with a shut-off valve core 30. One first valve body 13 and one shut-off valve core 30 constitute the high-pressure shut-off valve 101 of the air conditioner 1000, and the other first valve body 13 and the other shut-off valve core 30 constitute the low-pressure shut-off valve 102 of the air conditioner 1000. The valve island 10 also includes a mounting plate 11, on which both first valve bodies 13 are mounted.

[0149] In the above technical solution, the two first valve bodies 13 are jointly mounted on a single mounting plate 11, forming an integrated structure. This makes the air conditioning valve 100 compact and saves installation space. Simultaneously, the unified mounting plate 11 helps improve the structural stability and connection reliability between the two valve bodies, reduces the number of pipe connections, and lowers the risk of leakage. Furthermore, the air conditioning valve 100 has a simple structure, facilitating connection with the indoor unit 400 and outdoor unit 500, thus improving the ease of operation of the air conditioner 1000.

[0150] In some technical solutions, the two first valve bodies 13 can be arranged on the same side of the valve island 10 to make the structure more compact and facilitate centralized connection of pipelines. Of course, in this application, the two first valve bodies 13 can also be arranged on different sides of the mounting plate 11 to adapt to the system layout requirements in different directions and improve installation flexibility.

[0151] In some alternative embodiments, the two first valve bodies 13 are located on the same side of the mounting plate 11, and the operating ports 135 on the two first valve bodies 13 face the same direction.

[0152] The design of having all 135 operating ports facing the same direction facilitates unified operation, allowing operators to work from the same side and improving ease of use and work efficiency. At the same time, the more regular structural layout facilitates pipe connections and system integration.

[0153] Alternatively, in some technical solutions, the operating ports 135 of the two first valve bodies 13 face different directions. This is to accommodate different operational needs or avoid interference from surrounding structures, thereby improving the convenience of installation and maintenance.

[0154] Of course, this application is not limited to this. In some technical solutions, the two first valve bodies 13 can also be located on different sides of the mounting plate 11, and the operating ports 135 on the two first valve bodies 13 may face the same or different directions. This configuration of the air conditioning valve 100 can adapt to the complex structure and space constraints of the air conditioner 1000, and the operating position can be flexibly adjusted according to the actual installation environment, improving maintenance convenience. The orientation of the operating ports 135 also offers considerable flexibility, making the overall structure of the air conditioning valve 100 more rational.

[0155] Alternatively, the first channels 132 on all the first valve bodies 13 are located on the same side of the mounting plate 11; the second channels 1331 on the second valve bodies 15 are located on the other side of the mounting plate 11.

[0156] This design helps simplify the layout of external pipes, avoids pipe crossings, tangles, and confusion on one side of the mounting plate, makes the pipe routing clearer, and thus improves the maintainability of the air conditioning valve 100 and reduces the risk of misconnection.

[0157] like Figure 1 , Figure 2 , Figure 8 and Figure 12 As shown, the air conditioning valve 100 according to some embodiments of the present invention further includes: a regulating valve 70, wherein the regulating valve 70 is at least one of an expansion valve 71 and a four-way valve 72, and the regulating valve 70 is mounted on the valve island 10.

[0158] By integrating at least one of the expansion valve 71 and the four-way valve 72 onto the valve island 10, the air conditioning valve 100 can integrate more functions while reducing the additional space and piping connections required to install these components separately, simplifying piping connections, improving structural stability, and further reducing leakage.

[0159] It is worth noting that the installation positions of the expansion valve 71, the four-way valve 72, and the first valve body 13 are highly flexible. These components can all be installed on the same side of the mounting plate 11, or some can be installed on the same side and the rest on different sides, depending on actual needs. By optimizing the relative positions of these components, the refrigerant flow path can be shortened, flow resistance reduced, structural interference avoided, and the structural compactness of the air conditioning valve 100 improved.

[0160] Furthermore, the regulating valve 70 has a valve port 703. The valve island 10 also has a connecting seat 80, which has a connecting channel 81. The two ends of the connecting channel 81 are an external port 811 and an internal port 812, respectively. The valve port 703 of the regulating valve 70 is connected to the internal port 812. There are at least two valve ports 703, and the connecting channels 81 are configured to correspond one-to-one with the valve ports 703.

[0161] The connection channel 81 is mounted on the valve island 10 via the connection seat 80. This improves the structural stability of the connection channel 81. Furthermore, each valve port 703 corresponds to a specific connection channel 81, making the fluid path clear and easy to maintain later.

[0162] Meanwhile, the connecting channel 81 is formed on the connecting seat 80. This means that when the regulating valve 70 needs to be replaced or repaired, only the connection between the connecting seat 80 and the valve island 10 needs to be disassembled, without replacing the entire air conditioning valve 100, thus improving maintenance convenience. Furthermore, integrating the connecting channel 81 onto the connecting seat 80 facilitates modular design, improves assembly efficiency, and allows for flexible replacement of connecting seats 80 with different flow channel configurations to meet different needs, enhancing the adaptability and expandability of the air conditioning valve 100.

[0163] The two ends of the connecting channel 81 are an external interface 811 and an internal interface 812, respectively. The internal interface 812 is used to connect to the valve interface 703 of the regulating valve 70, while the external interface 811 is used to connect to external pipelines. The connecting channel 81 is set to correspond one-to-one with each valve interface 703 of the regulating valve 70 to ensure accurate connection of the fluid path.

[0164] For example, the regulating valve 70 includes an expansion valve 71, the valve port 703 of which is connected to an internal port 812 of a connecting channel 81. Alternatively, the regulating valve 70 includes a four-way valve 72, the port of which is connected to an internal port 812 of a connecting channel 81.

[0165] When the regulating valve 70 includes an expansion valve 71 and a four-way valve 72, two corresponding connection channels 81 are provided, which are connected to the valve interfaces 703 of the expansion valve 71 and the four-way valve 72 respectively, to ensure the independence of their respective fluid paths.

[0166] In some other technical solutions, the air conditioning valve 100 also includes a sealing ring 32, which is sleeved on the outer periphery of the shut-off valve core 30.

[0167] By setting the sealing ring 32, the sealing ring 32 is always in close contact with the inner wall of the intermediate channel 131 during the movement of the shut-off valve core 30 in the first direction, thereby achieving a reliable seal between the shut-off valve core 30 and the inner wall of the intermediate channel 131 and effectively preventing media leakage.

[0168] In some alternative embodiments, the sealing ring 32 is disposed at the end of the shut-off valve core 30 and near the operating end 31.

[0169] Alternatively, an annular sealing groove can be formed on the outer wall of the shut-off valve core 30 near the operating end 31, and the sealing ring 32 can be embedded therein. Alternatively, an annular sealing groove can be formed on the inner wall of the operating channel 134, and the sealing ring 32 can be embedded in the annular sealing groove. This prevents the sealing ring 32 from shifting or falling off during operation and improves sealing stability.

[0170] An air conditioner 1000 according to a second aspect of the present invention includes an air conditioning valve 100 according to a first aspect of the present invention.

[0171] It is worth noting that the type of air conditioner 1000 according to the embodiments of this application is not limited, and can be a wall-mounted air conditioner or a floor-standing air conditioner, etc. Once the type of air conditioner 1000 is determined, the shape of the valve island 10, as well as the number and position of the first valve body 13, can be adaptively designed.

[0172] By adopting the improved air conditioning valve 100, the structure of the air conditioner 1000 is stabilized, the piping complexity is reduced, and the reliability of use is improved.

[0173] The following is for reference. Figure 1 - Figure 3 , Figures 6-13 The air conditioning valve 100 according to a specific embodiment of the present invention is described in detail below. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0174] Reference Figures 1-3 The air conditioning valve 100 includes: valve island 10, shut-off valve core 30, first sealing component 51, second sealing component 52, valve core assembly 60, regulating valve 70, and connecting seat 80.

[0175] The valve island 10 includes: a mounting plate 11, two first valve bodies 13 and two second valve bodies 15.

[0176] Both first valve bodies 13 are mounted on the mounting plate 11 and located on the same side of the mounting plate 11. Each second valve body 15 is correspondingly mounted on one first valve body 13, and the second valve body 15 is located on the side of the first valve body 13 away from the mounting plate 11. The second valve body 15 and the first valve body 13 are integrally formed.

[0177] Reference Figures 6-13 Each first valve body 13 includes: an intermediate channel 131, a first channel 132, a first connecting pipe 133, and an operating channel 134.

[0178] Among them, the second channel 1331 is formed within the first receiver 133.

[0179] The first channel 132 is connected to the intermediate channel 131 through the first port 1321; the second channel 1331 is connected to the intermediate channel 131 through the second port 1333. The end of the first connecting pipe 133 away from the intermediate channel 131 forms the first interface 1332, which is used to connect the indoor and outdoor unit connecting pipes.

[0180] The first valve body 13 is also provided with an operation port 135, which is connected to the intermediate channel 131 through an operation channel 134. The inner wall of the operation channel 134 is provided with internal threads. The internal threads are distributed on the inner wall of the operation channel 134 and partially distributed on the inner wall of the intermediate channel 131, up to the first port 1321.

[0181] The operating port 135 and the first port 1321 are arranged along a first direction. The intermediate channel 131 and the second channel 1331 extend along a second direction, which is perpendicular to the first direction. The operating ports 135 on the two first valve bodies 13 face the same direction.

[0182] Each first valve body 13 is equipped with a shut-off valve core 30.

[0183] At least a portion of the shut-off valve core 30 is movably disposed within the intermediate channel 131. The shut-off valve core 30 is reciprocating along a first direction and switches between a shut-off position and an open position. The shut-off valve core 30 is provided with an external thread that mates with an internal thread. In the first direction, the length of the external thread is greater than the length of the intermediate channel 131.

[0184] When the shut-off valve core 30 is in the shut-off position, it blocks the first port 1321, thus cutting off the connection between the first channel 132 and the second channel 1331. When the shut-off valve core 30 is in the open position, it moves away from the first port 1321, allowing the first channel 132 and the second channel 1331 to connect through the intermediate channel 131. The diameter of the first port 1321 is smaller than the diameter of the shut-off valve core 30, and an annular contact line is formed between the shut-off valve core 30 and the inner wall of the first port 1321 when the valve is in the shut-off position.

[0185] The shut-off valve core 30 includes an operating end 31 located at the operating port 135. The operating end 31 is a non-circular countersunk hole, which allows external parts to cooperate with the operating end 31 through the operating port 135 to make the shut-off valve core 30 move.

[0186] The diameter of the operating port 135 is smaller than the diameter of the operating channel 134, and an annular stepped surface 1341 is formed at the connection between the operating port 135 and the operating channel 134.

[0187] When the shut-off valve core 30 is in the open position, a portion of the shut-off valve core 30 is always assembled in the operating channel 134, and the shut-off valve core 30 abuts against the annular stepped surface 1341.

[0188] A sealing ring 32 is fitted on the shut-off valve core 30, and the sealing ring 32 is at least partially located between the intermediate channel 131 and the operating port 135.

[0189] The first sealing element 51 is used to open and close the first interface 1332.

[0190] The second valve body 15 is provided with a filling channel 151. One end of the filling channel 151 is connected to the intermediate channel 131, and the other end forms a second interface 1511.

[0191] The second sealing element 52 is a cover and is threadedly connected to the second valve body 15 to open and close the second port 1511.

[0192] The regulating valve 70 includes an expansion valve 71 and a four-way valve 72. Both the expansion valve 71 and the four-way valve 72 are mounted on the valve island 10.

[0193] The regulating valve 70 has a valve port 703. The connecting seat 80 is provided with a connecting channel 81. The two ends of the connecting channel 81 are an external port 811 and an internal port 812, respectively, and the valve port 703 of the regulating valve 70 is connected to the internal port 812.

[0194] Other components of the air conditioning valve 100 according to the present invention, such as the first sealing member 51 and the second sealing member 52, as well as their operation, are known to those skilled in the art and will not be described in detail here.

[0195] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0196] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
