[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, 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, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. 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.

[0026] The valve island assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figures 1-6 and Figures 12-17 As shown, the valve island assembly 100 according to an embodiment of the present invention includes a valve 1 and a valve island 2.

[0028] The valve component 1 includes a main body 11 and multiple connecting pipes 12. The connecting pipes 12 are located on the main body 11, and the number of connecting pipes 12 is N, satisfying N≥3. At least one connecting pipe 12 of the valve component 1 is located within a valve island 2. The valve island 2 has multiple flow channels 21 corresponding one-to-one with each of the multiple connecting pipes 12, and the connecting pipes 12 extend into the corresponding flow channels 21. The valve component 1 can be a directional control valve, which can be a rotary three-way valve, a rotary four-way valve, a rotary five-way valve, an electrically operated three-way valve, an electrically operated four-way valve, or an electrically operated five-way valve.

[0029] Therefore, the valve island assembly 100 of this application, through multiple connecting parts 12 and multiple flow channels 21 corresponding to each of the multiple connecting parts 12, allows the flowing medium to flow within the multiple connecting parts 12 and the corresponding flow channels 21. Under the action of the valve core, the flow direction of the flowing medium within the valve element 1 changes, thereby supporting the switching of more functional modes (such as cooling / heating / defrosting). It should be noted that the specific structure and operation for realizing the change of the flow direction of the flowing medium within the valve element 1 under the action of the valve core are described in detail below.

[0030] At least N-1 connecting parts 12 have sealing rings 3 between their outer walls and the inner walls of their corresponding flow channels 21. When multiple connecting parts 12 are installed in the valve island 2, the sealing rings 3 are deformed by the pressure of the inner walls of the corresponding flow channels 21, thereby filling the contact area between the sealing rings 3 and the inner walls of the flow channels 21 to achieve a sealing effect and prevent leakage between different flow channels 21. At the same time, since at least N-1 connecting parts 12 and their corresponding flow channels 21 are directly elastically sealed by the sealing rings 3, even if there is no sealing ring 3 between one connecting part 12 and its corresponding flow channel 21, cross-flow or leakage of the medium between the connecting parts 12 or the flow channels 21 can be effectively prevented. This allows the flowing medium to flow within the valve island assembly 100 according to a specified path, maintaining stable and reliable sealing performance and pressure resistance even under complex reversing conditions of the air conditioning system, thereby improving the overall reliability of the valve island assembly 100.

[0031] For example, such as Figures 1-6 As shown, when there are four nozzles 12, at least three nozzles 12 have sealing rings 3 between their outer wall surfaces and the corresponding inner wall surfaces of the flow channels 21; or, as... Figures 12-17As shown, when there are three connecting pipe sections 12, at least two of the connecting pipe sections 12 have sealing rings 3 between their outer wall surfaces and the inner wall surfaces of their corresponding flow channels 21. Simultaneously, multiple sealing rings 3 can be provided between the outer wall surfaces of the connecting pipe sections 12 and the inner wall surfaces of their corresponding flow channels 21. These multiple sealing rings 3 are spaced apart along the length of the connecting pipe section 12 to improve the sealing effect.

[0032] Furthermore, by having at least one connecting part 12 of the valve component 1 located within the valve island 2, the multiple flow paths of the valve component 1 and the multiple flow channels 21 of the valve island 2 are integrated, thereby achieving miniaturization and centralization of the valve island assembly 100. This results in a compact overall structure and small size for the valve island assembly 100, effectively reducing installation space and pipe length. Simultaneously, this highly integrated valve island assembly 100 facilitates rapid docking with heat exchangers or compressors in different locations. The number of connecting parts 12 in the valve island assembly 100 can be flexibly set according to actual needs, improving the versatility of the valve island assembly 100 while achieving system miniaturization and centralized management.

[0033] It should be noted that there is no limit to the number of takeover units 12. Figure 7 Four connecting parts 12 are shown for illustrative purposes. Figure 18 The diagram shows three connecting parts 12 for illustrative purposes, but those skilled in the art, after reading the following technical solution, will obviously understand that the solution can be applied to a solution with five or more connecting parts 12, which also falls within the protection scope of this utility model.

[0034] It should be noted that the embodiments of this application do not impose specific restrictions on the type of valve 1. For example, valve 1 can be a switch valve, check valve, directional valve, flow regulating valve, or pressure regulating valve, etc. For example, valve 1 can be a shut-off valve, solenoid valve, electronic expansion valve, four-way directional valve, etc.

[0035] According to the valve island assembly 100 of this utility model embodiment, the valve component 1 includes a main body 11 and a plurality of connecting pipes 12. The connecting pipes 12 are disposed on the main body 11, and the number of connecting pipes 12 is N, satisfying N≥3. At least one connecting pipe 12 of the valve component 1 is located inside the valve island 2. The valve island 2 has a plurality of flow channels 21 corresponding one-to-one with the plurality of connecting pipes 12. The connecting pipes 12 extend into the corresponding flow channels 21 so that the flowing medium can flow in the plurality of connecting pipes 12 and the corresponding flow channels 21. This achieves the integrated arrangement of the multiple flow paths of the valve component 1 and the multiple flow channels 21 of the valve island 2, making the overall structure of the valve island assembly 100 compact and small in size, effectively reducing installation space and pipeline length. At the same time, by having sealing rings 3 between the outer wall surface of at least N-1 connecting pipes 12 and the inner wall surface of the corresponding flow channels 21, leakage of the flowing medium between different flow channels 21 is prevented, ensuring that the flowing medium can flow in the valve island assembly 100 according to the prescribed path, thereby improving the overall reliability of the valve island assembly 100.

[0036] In some embodiments of this utility model, such as Figure 4 , Figure 7 and Figure 8 As shown, the outer wall surface of the connecting pipe 12 has a groove 1211, which extends along the circumferential direction of the connecting pipe 12, and the sealing ring 3 is located in the groove 1211. Thus, the groove 1211 ensures that the sealing ring 3 is always maintained in a predetermined position, effectively preventing the sealing ring 3 from being pushed out and failing when the connecting pipe 12 extends into the valve island 2, and ensuring tight contact between the sealing ring 3 and the inner wall surface of the flow channel 21, so that the sealing ring 3 is sufficiently compressed, thereby optimizing the sealing performance.

[0037] In some embodiments of this utility model, the main body 11 includes a valve body and a valve core (not shown in the figure). The valve body is located within the valve island 2 and has a valve cavity (not shown in the figure). The connecting pipe 12 is disposed on the valve body and communicates with the valve cavity. The valve core is movably disposed within the valve cavity to switch the communication state of the connecting pipe 12.

[0038] Thus, by moving up and down or rotating the valve core within the valve cavity, the connection state between each connecting section 12 is controlled, thereby achieving connection or disconnection between different connecting sections 12, thereby changing the flow direction of the flowing medium within the valve component 1. Simultaneously, as the valve core changes the flow direction of the flowing medium within the valve component 1, the connection of multiple flow channels 21 within the valve island 2 also changes accordingly, thereby directly completing the distribution and reversal within the valve island assembly 100.

[0039] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 7 As shown, valve component 1 also includes a coil structure 13. The coil structure 13 is sleeved on the valve body and located outside the valve island 2, and is adapted to drive the valve core. Thus, by attracting or pushing the valve core through the coil structure 13, the communication state between the various connecting parts 12 is controlled, realizing the on / off or reversal of the fluid medium. Simultaneously, using the coil structure 13 to drive the valve core allows for rapid response to switching commands, making the flow direction switching action within the valve island assembly 100 flexible and reliable.

[0040] For example, coil structure 13 includes an electromagnetic coil that electromagnetically engages with the valve core to drive the valve core to move. Taking an electronic expansion valve as an example, the electromagnetic coil can be used to receive the electronic expansion valve opening control signal (e.g., a pulse signal) and control the opening of the electronic expansion valve according to the electronic expansion valve opening control signal. It should be noted that the method of the electromagnetic coil engaging with the valve core to drive the valve core to move is well known to those skilled in the art and will not be described in detail here.

[0041] Meanwhile, the coil structure 13 is located outside the valve body and outside the valve island 2, so that there is no need to provide space for the coil structure 13 inside the valve body, which makes it easier to set at least most of the outer peripheral wall of the valve body into a cylindrical form, simplifying the valve body structure and facilitating processing.

[0042] In some embodiments of this utility model, such as Figure 3 , Figures 6-11 As shown, there are four connecting parts 12, including a first connecting part 121, a second connecting part 122, a third connecting part 123, and a fourth connecting part 124. In the first working condition, the first connecting part 121 and the third connecting part 123 are connected, and the second connecting part 122 and the fourth connecting part 124 are connected. In the second working condition, the first connecting part 121 and the second connecting part 122 are connected, and the third connecting part 123 and the fourth connecting part 124 are connected.

[0043] Thus, by setting up four connecting parts 12, the four-way valve can switch between two working conditions (first working condition and second working condition) inside the valve island assembly 100. By having sealing rings 3 between the outer wall surface of at least N-1 connecting parts 12 and the inner wall surface of the corresponding flow channel 21, leakage between the flowing media in different flow channels 21 is prevented, ensuring that the flowing media can still flow in the valve island assembly 100 according to the prescribed path under different working conditions.

[0044] Specifically, such as Figure 3 and Figure 6 As shown, the flow channel 21 includes a first flow channel 211 corresponding to the first connecting part 121, a second flow channel 212 corresponding to the second connecting part 122, a third flow channel 213 corresponding to the third connecting part 123, and a fourth flow channel 214 corresponding to the fourth connecting part 124. In the first operating condition, the valve core repositioning connects the first connecting part 121 to the third connecting part 123 and the second connecting part 122 to the fourth connecting part 124. The flowing medium enters the valve island assembly 100 from the first flow channel 211 away from the first connecting part 121, and enters the valve cavity through the first flow channel 211 and the first connecting part 121. Then, it flows into the third connecting part 123 through the valve core, and flows through the third connecting part 123 to the third flow channel 213, and then flows out of the valve island assembly 100 from the end of the third flow channel 213 away from the third connecting part 123. At the same time, the flowing medium enters the valve island assembly 100 from the second flow channel 212 away from the second connecting part 122, and enters the valve cavity through the second flow channel 212 and the second connecting part 122. Then, it flows into the fourth connecting part 124 through the valve core, and flows through the fourth connecting part 124 to the fourth flow channel 214, and then flows out of the valve island assembly 100 from the end of the fourth flow channel 214 away from the fourth connecting part 124.

[0045] In the second operating condition, the valve core repositions again, connecting the first connecting part 121 to the second connecting part 122 and the third connecting part 123 to the fourth connecting part 124. The flowing medium enters the valve island assembly 100 from the first flow channel 211 away from the first connecting part 121, and enters the valve cavity through the first flow channel 211 and the first connecting part 121. Then, it flows into the second connecting part 122 through the valve core, and flows through the second connecting part 122 to the second flow channel 212, and then flows out of the valve island assembly 100 from the end of the second flow channel 212 away from the second connecting part 122. At the same time, the flowing medium enters the valve island assembly 100 from the third flow channel 213 away from the third connecting part 123, and enters the valve cavity through the third flow channel 213 and the third connecting part 123. Then, it flows into the fourth connecting part 124 through the valve core, and flows through the fourth connecting part 124 to the fourth flow channel 214, and then flows out of the valve island assembly 100 from the end of the fourth flow channel 214 away from the fourth connecting part 124.

[0046] In some embodiments of this utility model, such as Figure 14 , Figures 17-19 As shown, there are three connecting parts 12, including a fifth connecting part 125, a sixth connecting part 126, and a seventh connecting part 127. In the first operating condition, the fifth connecting part 125 and the sixth connecting part 126 are connected; in the second operating condition, the sixth connecting part 126 and the seventh connecting part 127 are connected. Thus, this arrangement enables dual-condition (first and second operating conditions) switching within the valve island assembly 100 when there are three connecting parts 12. Furthermore, the presence of sealing rings 3 between the outer walls of at least N-1 connecting parts 12 and the inner walls of the corresponding flow channels 21 prevents leakage of the flowing media between different flow channels 21, ensuring that the flowing media can still flow within the valve island assembly 100 according to the prescribed path under different operating conditions.

[0047] Specifically, flow channel 21 includes a fifth flow channel 215 corresponding to the fifth connecting section 125, a sixth flow channel 216 corresponding to the sixth connecting section 126, and a seventh flow channel 217 corresponding to the seventh connecting section 127. In the first operating condition, the valve core is repositioned to connect the fifth connecting section 125 and the sixth connecting section 126. The flowing medium enters the valve island assembly 100 from the end of the fifth flow channel 215 away from the fifth connecting section 125, and enters the valve cavity through the fifth flow channel 215 and the fifth connecting section 125. Then, it flows into the sixth connecting section 126 through the valve core, and flows to the sixth flow channel 216 through the sixth connecting section 126. Finally, it flows out of the valve island assembly 100 from the end of the sixth flow channel 216 away from the sixth connecting section 126. At the same time, the seventh connecting section 127 is blocked by the valve core, and there is no medium flowing in the seventh flow channel 217.

[0048] In the second operating condition, the valve core is repositioned again to connect the sixth connecting part 126 and the seventh connecting part 127. The flowing medium enters the valve island assembly 100 from the end of the sixth flow channel 216 away from the sixth connecting part 126, and enters the valve cavity through the sixth flow channel 216 and the sixth connecting part 126. Then it flows into the seventh connecting part 127 through the valve core, and flows to the seventh flow channel 217 through the seventh connecting part 127 and then flows out of the valve island assembly 100 from the end of the seventh flow channel 217 away from the seventh connecting part 127. At the same time, the fifth connecting part 125 is blocked by the valve core, and there is no medium flowing in the fifth flow channel 215.

[0049] In some embodiments of this utility model, such as Figure 7 and Figure 18 As shown, multiple connecting parts 12 are located on the same side of the main body 11. This arrangement ensures that when the valve component 1 mates with the valve island 2, all connecting parts 12 extend in the same direction, thereby simplifying installation, optimizing the layout of the valve island assembly 100, and further miniaturizing the valve island assembly 100.

[0050] In some embodiments of this utility model, such as Figure 3 , Figure 4 , Figure 7 , Figure 14 , Figure 15 and Figure 18 As shown, the main body 11 has a mounting portion 111 that extends along the circumferential direction of the valve component 1 and is connected to the valve island 2. Thus, the main body 11 is connected to the valve island 2 via the mounting portion 111, and the mounting portion 111 provides a reliable fixing surface for the valve component 1, ensuring stable positioning of the valve component 1 and tight engagement with the valve island 2 during valve island assembly 100 installation. This guarantees that the valve component 1 maintains sealing and structural stability when subjected to pipeline pressure and operational vibration.

[0051] In some embodiments of this utility model, such as Figure 4 and Figure 15 As shown, the valve island 2 has a mounting groove 22, the bottom wall of which has a first groove 221 and a second groove 222. At least a portion of the main body 11 is located in the first groove 221, and the mounting part 111 is located in the mounting groove 22. The valve island assembly 100 also includes a fixing part 4. The fixing part 4 is located in the second groove 222 and is connected to the second groove 222 by brazing. The fixing part 4 and the mounting part 111 are directly welded together. The mounting part 111 is made of stainless steel, the fixing part 4 is made of stainless steel, and the valve island 2 is made of aluminum.

[0052] Thus, the first groove 221 is used to accommodate the main body 11 of the valve component 1 to limit the main body 11, ensuring that the sealing ring 3 at the connecting pipe 12 is effectively sealed after assembly due to the pressure of the inner wall of the corresponding flow channel 21, and the second groove 222 is used to accommodate the fixing part 4 and provide welding operation space and heat insulation distance, reducing the impact on the valve component 1.

[0053] Meanwhile, when the valve island 2 is made of aluminum and the mounting part 111 is made of stainless steel, in order to prevent the valve island 2 from undergoing electrochemical corrosion, a stainless steel fixing part 4 is introduced into the second groove 222 as an indirect component. The fixing part 4 is connected to the second groove 222 by brazing and the mounting part 111 by direct welding, thereby realizing the indirect connection between the mounting part 111 and the valve island 2, and thus realizing the connection between the valve body and the valve island 2.

[0054] Furthermore, the mounting part 111 and the fixing part 4 are directly welded together, which can accommodate various welding methods, such as butt welding, lap welding, fillet welding, etc. For example, as Figure 4 and Figure 15 As shown, taking the axial direction of the mounting part 111 as the up-down direction as an example, the upper surface of the welding position of the mounting part 111 and the upper surface of the fixing part 4 can be flush.

[0055] Furthermore, the fixing part 4 and the second groove 222 are connected by brazing, specifically by brazing with solder: the solder wets and fills the mating surface of the second groove 222 and the fixing part 4 to form a dense brazing seam, thereby achieving high connection strength and stable sealing.

[0056] Furthermore, the fixing part 4 and the mounting part 111 are directly welded together, specifically by direct laser melting welding: the laser rapidly melts the connection area locally and forms a continuous weld, achieving high connection strength, good overall rigidity, and reliable sealing under vibration and internal pressure impact.

[0057] Specifically, the assembly sequence of the valve island assembly 100 is as follows: first, the stainless steel fixing part 4 is welded to the side wall of the second groove 222 of the valve island 2; then, at least a portion of the main body part 11 of the valve component 1 is located in the first groove 221, and the mounting part 111 is located in the mounting groove 22, so that the connecting pipe part 12 and the sealing ring 3 in the corresponding flow channel 21 are in effect under compression; finally, the stainless steel mounting part 111 and the stainless steel fixing part 4 are directly welded together in an annular shape.

[0058] Furthermore, the brazing connection between the mounting part 111 and the side wall of the second groove 222 helps to reduce the thermal impact of welding on the mounting part 111. At the same time, the brazing of stainless steel and aluminum helps to reduce the electrochemical corrosion rate and enables reliable welding between two different materials. When stainless steel is directly welded to stainless steel, the base materials have the same or similar melting points. The laser beam energy is concentrated, the local temperature is high, and it can quickly melt the local part of the base material to form a weld. The heat-affected zone is very small, and the welding time is short and the welding speed is fast.

[0059] In some embodiments of this utility model, the valve island 2 has a mounting groove 22, the bottom wall of which has a first groove 221 and a second groove 222. At least a portion of the main body 11 is located within the first groove 221, and the mounting part 111 is located within the mounting groove 22. Thus, by limiting the main body 11 through the first groove 221, the connecting pipe 12 is aligned with the corresponding flow channel 21. After assembly, the sealing ring 3 is effectively compressed by the inner wall of the flow channel 21, ensuring a sealing effect. Simultaneously, the second groove 222 provides space and heat insulation distance for welding operations, reducing the impact of heat input on the valve 1, and facilitating the formation of continuous and uniform welds, thereby improving the stability of the fit between the main body 11 and the valve island 2, as well as their vibration and pressure resistance.

[0060] In some embodiments of this invention, the mounting part 111 is made of stainless steel, and the valve island 2 is made of aluminum. The mounting part 111 and the mounting groove 22 are connected by brazing. Thus, by brazing the stainless steel mounting part 111 and the aluminum valve island 2, a reliable connection can be achieved with lower heat input, reducing the heat-affected zone and deformation between the valve body and the valve island 2. Simultaneously, brazing can form a continuous and dense connection interface, which is beneficial for long-term sealing and fatigue resistance. Compared to fusion welding, brazing can reduce the electrochemical corrosion rate of dissimilar metals, improving service life and environmental adaptability.

[0061] In some embodiments of this utility model, the mounting part 111 is made of stainless steel, and the valve island 2 is made of cast iron or stainless steel. The mounting part 111 is directly welded to the mounting groove 22. When the valve island 2 is made of stainless steel, it has good compatibility with the stainless steel mounting part 111, facilitating direct welding between the mounting part 111 and the mounting groove 22; or, when the valve island 2 is made of cast iron, it effectively enhances the overall load-bearing capacity of the valve island 2, thereby improving overall reliability.

[0062] In some embodiments of this utility model, such as Figure 1 , Figure 3 , Figure 6 , Figure 12 , Figure 14 and Figure 17As shown, the valve island assembly 100 also includes pipe connectors 5. Each pipe connector 5 corresponds one-to-one with a plurality of flow channels 21. At least a portion of each pipe connector 5 is located outside the valve island 2, and one end of each pipe connector 5 is connected to the end of the corresponding flow channel 21 away from the connecting pipe portion 12.

[0063] Therefore, by setting pipe joints 5 corresponding to each flow channel 21 in the valve island assembly 100, the pipe joints 5 lead out to the outside of the valve island 2 and connect to external pipelines or other system components (such as compressors, indoor / outdoor heat exchangers), thereby enabling the flow medium inside the valve island assembly 100 to flow out through the pipe joints 5 or the flow medium from the outside to flow into the valve island assembly 100 through the pipe joints 5. At the same time, under the action of the valve core, the flow direction of the flow medium in the valve element 1 switches according to the operating conditions, so that the pipe joints 5 can serve as both the flow medium output end of the valve island assembly 100 and, when needed, the input end to complete the flow medium introduction in the opposite direction. This allows the multiple flow channels 21 inside the valve island assembly 100 to reliably transport and switch multiple branches of the medium with the external system through the corresponding external pipe joints 5.

[0064] In some embodiments of this utility model, such as Figure 3 , Figure 6 , Figure 14 and Figure 17 As shown, the pipe fitting 5 and the connecting pipe 12 extend in the same direction. This arrangement reduces flow loss of the fluid medium and facilitates the layout of the flow channels 21 within the valve island 2, thus improving the compactness of the valve island 2 structure.

[0065] In some embodiments of this utility model, the pipe joint 5 is welded to the valve island 2, thereby forming a continuous metal connection interface through welding, so as to make the connection strength between the pipe joint 5 and the valve island 2 high, ensure reliable sealing, and improve reliability.

[0066] In some embodiments of this utility model, the pipe joint 5 and the valve island 2 are integrated into one piece, so that the connection interface between the pipe joint 5 and the valve island 2 is eliminated, the overall rigidity is improved, the sealing reliability is maintained under vibration and internal pressure impact conditions, and the number of parts and assembly processes is reduced at the same time.

[0067] In some embodiments of this utility model, multiple pipe joints 5 are located on the same side of the valve island 2, or at least two pipe joints 5 are located on different sides of the valve island 2. It is understood that when multiple pipe joints 5 are located on the same side of the valve island 2, the inlet and outlet of the pipe joints 5 can be integrated on one side, reducing crossing and mutual interference; or, when at least two pipe joints 5 are located on different sides (which can be opposite sides or adjacent sides), the pipe joints 5 can be connected to the corresponding connecting components (e.g., compressors, indoor / outdoor heat exchangers, etc.) nearby, shortening the pipeline length and reducing structural interference. Therefore, multiple pipe joints 5 can be located on the same side or different sides of the valve island 2 according to the setting scenario of the valve island assembly 100, improving versatility. For example, as... Figure 1 and Figure 12 As shown, multiple pipe fittings 5 ​​are located on opposite sides of the valve island 2.

[0068] The following describes an air conditioner according to an embodiment of the present invention.

[0069] An air conditioner according to an embodiment of the present invention includes a valve island assembly 100.

[0070] According to an embodiment of the present invention, an air conditioner includes a valve island assembly 100. The valve 1 includes a main body 11 and multiple connecting pipes 12. The connecting pipes 12 are located on the main body 11, and the number of connecting pipes 12 is N, satisfying N≥3. At least one connecting pipe 12 of the valve 1 is located within a valve island 2. The valve island 2 has multiple flow channels 21 corresponding one-to-one with the multiple connecting pipes 12. The connecting pipes 12 extend into the corresponding flow channels 21, allowing the flowing medium to flow within the multiple connecting pipes 12 and the corresponding flow channels 21. This integrated arrangement of multiple flow paths of the valve 1 and multiple flow channels 21 of the valve island 2 results in a compact overall structure and small size for the valve island assembly 100, effectively reducing installation space and pipe length. Simultaneously, sealing rings 3 are provided between the outer wall surfaces of at least N-1 connecting pipes 12 and the inner wall surfaces of the corresponding flow channels 21, preventing mutual leakage of the flowing medium between different flow channels 21 and ensuring that the flowing medium can flow within the valve island assembly 100 according to a predetermined path, thereby improving the overall reliability of the air conditioner.
