[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the valve core assembly for a one-way valve, the one-way valve for an air conditioner and the air conditioner provided by the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] The air conditioning check valve is one of the important components of the air conditioner. It can control the flow direction of the refrigerant and ensure the normal operation of the system. It is an indispensable part of the air conditioning system. In the air conditioning check valve, the valve core assembly is the core component that controls whether the refrigerant can flow.

[0034] like Figure 1 As shown, in some related technologies, the valve core assembly includes: a housing 1, a valve port member 2 and a valve core 3, the housing 1 includes: a pipe section 4 and a limit section 5, the pipe section 4 and the limit section 5 are integrally formed by stretching or stamping. The valve core 3 and the valve port member 2 are both arranged in the limit section 5, and the limit section 5 is provided with a flow hole 6. The valve core 3 blocks or opens the valve port 7 on the valve port member 2 by moving, and the pipe section 4 is used to be plugged with the pipeline.

[0035] However, since the shell 1 is integrally formed by stretching or stamping, the wall thickness of the shell 1 is relatively small, especially since the pipe section 4 has no support inside. During transportation or assembly, if it encounters radial external force, it is easy to deform, so that its cross section is no longer circular, resulting in inability to be plugged into the pipeline, thereby affecting the assembly efficiency.

[0036] In order to solve the above problems, the utility model discloses a valve core assembly for a one-way valve. The one-way valve is used to be connected between a first pipeline 60 and a second pipeline 70. When the fluid flows from the first pipeline 60 to the second pipeline 70, the one-way valve is opened to connect the first pipeline 60 and the second pipeline 70, and the refrigerant can flow from the first pipeline 60 to the second pipeline 70; when the refrigerant flows from the second pipeline 70 to the first pipeline 60, the one-way valve is closed to cut off the first pipeline 60 and the second pipeline 70, and the fluid cannot flow from the second pipeline 70 to the first pipeline 60.

[0037] The valve core assembly of the utility model can be applied to the one-way valve of the air conditioner, and can also be applied to the one-way valve of other refrigeration or heating equipment. The valve core assembly of the utility model is specifically described below by taking the one-way valve applied to the air conditioner as an example. It can be understood that when the valve core assembly is used for the one-way valve of the air conditioner, the fluid therein is the refrigerant.

[0038] like Figures 2 to 4 The first embodiment of the utility model shown discloses a valve core assembly for a one-way valve, including: an integrally formed housing 10, a valve port member 20, a valve core 30 and a reinforcement ring 40. The housing 10 is an integrally formed structure, and may have an inner cavity that penetrates axially, and a flow hole 121 that communicates with the inner cavity is provided on the outer peripheral wall of the housing 10. A valve port 21 that penetrates circumferentially is provided on the valve port member 20, and the valve port member 20 is arranged in the inner cavity and divides the inner cavity into a first cavity 111 and a second cavity 122, and the first cavity 111 is connected to the second cavity 122 through the valve port 21, and the flow hole 121 is connected to the second cavity 122. The valve core 30 is disposed in the second cavity 122, and the valve core 30 is movable between a closed valve position and an open valve position; in the closed valve position, the valve core 30 blocks the valve port 21 to prevent the fluid in the second cavity 122 from flowing to the first cavity 111; in the open valve position, the valve core 30 is separated from the valve port 21, and the fluid in the first cavity 111 flows out through the second cavity 122 and the flow hole 121 in sequence. The reinforcement ring 40 is disposed in the inner cavity, and the outer peripheral wall of the reinforcement ring 40 abuts against the inner peripheral wall of the inner cavity to support the housing 10 in the radial direction.

[0039] During use, when the refrigerant flows from the first cavity 111 to the second cavity 122, the valve core 30 moves from the closed valve position to the open valve position under the push of the refrigerant. At this time, the valve core 30 is separated from the valve port 21, and the first cavity 111 and the second cavity 122 are connected through the valve port 21; when the refrigerant flows from the second cavity 122 to the first cavity 111, the valve core 30 moves from the open valve position to the closed valve position under the action of the refrigerant. At this time, the valve core 30 blocks the valve port 21, so that the fluid in the second cavity 122 cannot flow to the first cavity 111.

[0040] The valve core assembly of the utility model is provided with a reinforcement ring 40 in the inner cavity of the shell 10, and the outer circumferential wall of the reinforcement ring 40 abuts against the inner circumferential wall of the inner cavity, so that the shell 10 can be supported in the radial direction. When the shell 10 is squeezed by external force in the radial direction, a part of the external force can be shared in the radial direction by the reinforcement piece, so as to prevent the shell 10 from deformation and make the overall strength of the shell 10 higher.

[0041] It should be noted that, in the present embodiment, the valve core 30 has a blocking end, and when the valve core 30 is in the valve closing position, the outer peripheral wall of the blocking end of the valve core 30 abuts against the inner wall of the valve port 21 to achieve blocking. However, this is not restrictive, and in some other embodiments not shown in the figure, when the valve core 30 is in the valve closing position, the blocking end of the valve core 30 can also be located outside the valve port 21. As long as the structure can achieve blocking between the valve core 30 and the valve port 21, it is within the protection scope of the present utility model without violating the inventive concept of the present utility model.

[0042] like Figure 2 As shown, in this embodiment, the shell 10 includes: a connecting pipe section 11 and a limiting section 12. The connecting pipe section 11 has a first end and a second end in the axial direction, a first cavity 111 is located in the connecting pipe section 11, and the first cavity 111 forms a first opening 112 at the first end of the connecting pipe section 11; the limiting section 12 has a first end and a second end in the axial direction, the first end of the limiting section 12 is connected to the second end of the connecting pipe section 11, and a first step portion 13 is formed at the connection between the limiting section 12 and the connecting pipe section 11, the valve mouth member 20 is located at the first end of the limiting section 12, and a second cavity 122 is formed between the valve mouth member 20 and the second end of the limiting section 12, the flow hole 121 is provided on the limiting section 12, and the second end of the limiting section 12 is formed with an opening structure, and the limiting section 12 is provided with a limiting portion 123 at the opening structure to prevent the valve core 30 from being separated from the shell 10 under the action of the refrigerant.

[0043] like Figure 2 As shown, the reinforcement ring 40 includes a first annular portion 41 . The first annular portion 41 is disposed in the first cavity 111 , the outer peripheral wall of the first annular portion 41 abuts against the inner peripheral wall of the first cavity 111 , and the inner peripheral wall of the first annular portion 41 forms a connecting channel 45 for connecting with the first pipeline 60 .

[0044] The first annular portion 41 has a first end and a second end in the axial direction, the first end of the first annular portion 41 extends to the position of the first opening 112, and the second end of the first annular portion 41 abuts against the first step portion 13. That is, in this embodiment, the first annular portion 41 is a cylindrical structure, the first end of the first annular portion 41 of the cylindrical structure extends to the position of the first opening 112, and the second end abuts against the first step structure, so as to achieve the limited cooperation with the housing 10 in the axial direction to prevent the first annular portion 41 from sliding relative to the housing 10 when the first pipeline 60 is plugged in.

[0045] It should be noted that the second end of the first annular portion 41 can directly abut against the first step portion 13, or can also abut against the first step portion 13 indirectly. As long as it can abut against the first step portion 13 to achieve axial limit fit. In this embodiment, the first annular portion 41 abuts against the first step portion 13 indirectly, and the specific structure is as follows:

[0046] like Figure 2 As shown, the valve member 20 has a first end and a second end in the axial direction, and the valve port 21 extends from the first end to the second end of the valve member 20. The outer peripheral wall of the first end of the valve member 20 forms an annular convex edge 22, and the first side of the annular convex edge 22 abuts against the first step portion 13, and the second end of the first annular portion 41 abuts against the second end of the annular convex edge 22 and abuts against the first step portion 13 through the annular convex edge 22. The valve member 20 is provided with an annular convex edge 22, so that it can be automatically assembled. Figure 2 The first opening 112 of the middle housing 10 is placed into the housing 10 and installed to the first end of the limiting section 12. Due to the presence of the annular convex edge 22, after being installed in place, the annular convex edge 22 will abut against the first step portion 13 to limit the position, thereby preventing the valve port member 20 from being installed too close to the second end of the limiting section 12, thereby affecting the movement of the valve core 30. In addition, after the first annular portion 41 is assembled, the second end of the first annular portion 41 abuts the annular convex edge 22 against the first step portion 13. After the first annular portion 41 is fixed to the housing 10, the valve port member 20 is also fixed, thereby avoiding the step of welding the valve port member 20 separately and simplifying the assembly process.

[0047] like Figure 3 and Figure 4 As shown, the first embodiment of the present invention is disclosed to be applied to a one-way valve and a scenario, wherein the one-way valve is used for air conditioning.

[0048] In this embodiment, if Figure 3 As shown, the one-way valve includes: a valve body 50 and the above-mentioned valve core assembly, and the valve core assembly is arranged in the valve body 50. Specifically, the valve body 50 is an integrally formed structure, and the valve body 50 has a first end and a second end in the axial direction, and the valve body 50 has a channel running from the first end to the second end thereof, and the valve core assembly is arranged in the channel.

[0049] The housing 10 is disposed in the valve body 50 , and has a first end and a second end in the axial direction. A gap is formed between a first end surface 113 of the first end of the housing 10 and a second end surface 511 of the first end of the valve body 50 in the axial direction.

[0050] Specifically, if Figure 3As shown, the valve body 50 includes: a first connection portion 51, a main body portion 52, and a second connection portion 53. In other words, in the axial direction of the valve body 50, the first connection portion 51, the main body portion 52, and the second connection portion 53 are sequentially connected, and the first connection portion 51, the main body portion 52, and the second connection portion 53 form an integrally formed structure. By adopting the integrally formed structure, the valve body 50 is formed into a whole, thereby improving the overall strength of the valve body 50.

[0051] The first connection portion 51 has a first end and a second end in the axial direction, wherein the first end of the first connection portion 51 is the first end of the valve body 50, a first passage penetrating axially is arranged inside the first connection portion 51, the outer peripheral wall of the pipe section 11 abuts against the inner peripheral wall of the first passage, the first opening 112 faces the first end of the first connection portion 51, and the first end of the first connection portion 51 has a second end face 511. The first end of the pipe section 11 in the axial direction is the first end of the housing 10 in the axial direction, and the first end of the pipe section 11 in the axial direction has a first end face 113, and there is a gap between the first end face 113 and the second end face 511 in the axial direction.

[0052] like Figure 3 and Figure 4 As shown, the reinforcement ring 40 has a first end and a second end in the axial direction. In this embodiment, the first end of the first annular portion 41 is the first end of the reinforcement ring 40 in the axial direction. The first end of the first annular portion 41 has a third end face 44, and the third end face 44 is flush with the first end face 113. A connecting channel 45 extending to the first end of the reinforcement ring 40 is formed inside, and the connecting channel 45 is used for plugging and matching with the first pipeline 60. Figure 3 As shown, when the first pipeline 60 is plugged into the connecting channel 45, the first pipeline 60 is connected to the valve port 21, and the outer peripheral wall of the first pipeline 60, the third end face 44, the first end face 113 and the outer peripheral wall of the valve body 50 near the first end form a receiving groove 80 for receiving the solder 90. During welding, after the solder 90 melts in the receiving groove 80, it can contact the first pipeline 60, the third end face 44 of the reinforcement ring 40, the first end face 113 of the shell 10, and the inner peripheral wall of the valve body 50 near the first end, so that the first pipeline 60, the reinforcement ring 40, the shell 10, and the valve body 50 are welded and fixed at one time, and the sealing between the first pipeline 60 and the reinforcement ring 40, the reinforcement ring 40 and the shell 10, and the shell 10 and the valve body 50 is completed, thereby improving the assembly efficiency. In addition, by providing the receiving groove 80, the contact area between the solder 90 and the first pipeline 60 and the valve body 50 is also increased, thereby improving the sealing and reliability of the connection.

[0053] like Figure 3As shown, the main body 52 has a first end and a second end along the axial direction, the first end of the main body 52 is connected to the second end of the first connecting part 51, and a second channel axially penetrating is arranged inside the main body 52, the limiting section 12 of the shell 10 is located in the second channel, the inner diameter of the first connecting part 51 is smaller than the inner diameter of the main body 52, and a flow space is formed between the outer peripheral wall of the limiting section 12 of the shell 10 and the inner peripheral wall of the second channel, and the second cavity 122 in the limiting section 12 is connected to the flow space through the flow hole 121. Since the inner diameter of the main body 52 is larger than the inner diameter of the first connecting part 51, the flow area of ​​the flow space can be made larger to reduce the resistance to the flow of the refrigerant.

[0054] like Figure 3 As shown, the second connection part 53 is cylindrical, and the second connection part 53 has a first end and a second end in the axial direction. The first end of the second connection part 53 is connected to the second end of the main body 52, and the second end of the second connection part 53 is used for plugging and matching with the second pipeline 70. A third channel is axially penetrated inside the second connection part 53, and the first channel, the second channel and the third channel are connected in sequence to form a channel. As shown in the figure, during assembly, the second pipeline 70 is inserted into the third channel from the second end of the second connection part 53, so that the second pipeline 70 is connected to the flow space in the second channel.

[0055] During use, when the refrigerant flows in from the first pipeline 60, under the action of the refrigerant, the valve core 30 in the closed valve position moves to the open valve position, so that the first cavity 111 is connected with the second cavity 122, and the refrigerant enters the second cavity 122 through the valve port 21, and then flows into the flow space through the flow port, and then flows into the second pipeline 70; when the refrigerant flows in the opposite direction, the refrigerant in the second pipeline 70 flows into the second channel, and a part of the refrigerant enters the second cavity 122 from the opening at the second end of the limiting section 12, and acts on the valve core 30. Under the action of the refrigerant, the valve core 30 moves from the open valve position to the closed valve position, thereby blocking the valve port 21, so that the refrigerant cannot flow into the first pipeline 60.

[0056] It should be noted that in the first embodiment, the first annular portion 41 is a cylindrical structure, but this is not restrictive. Figure 5 In the second embodiment shown, a valve core assembly is also disclosed, and its structure is basically the same as that of the first embodiment, except that, in this embodiment, the second end of the first annular portion 41 is formed with an inner fold 411 that abuts against the first end of the valve port member 20. In this way, on the one hand, the abutting area between the inner fold 411 and the first end of the valve port member 20 is larger, so that the force is more uniform; on the other hand, Figure 6The second embodiment shown is used in the scenario of a one-way valve. When the first pipeline 60 is plugged into the connecting channel 45 of the first annular portion 41, the first pipeline 60 can be pressed against the inner fold edge 411. The inner fold edge 411 and the annular flange 22 are pressed against the first step portion 13 through the first pipeline 60, making the connection more stable.

[0057] It should also be noted that in the above-mentioned embodiments 1 and 2, the valve port member 20 is provided with an annular convex edge 22, but this is not restrictive. Figure 7 In the third embodiment shown, a valve core assembly is also disclosed, and its structure is basically the same as that of the second embodiment. The difference is that in this embodiment, the first end of the valve mouth member 20 is not provided with an annular flange 22, and the valve mouth member 20 is fixedly connected to the housing 10 by welding or interference fit.

[0058] like Figure 8 In the fourth embodiment shown, a valve core assembly is also disclosed, and its structure is basically the same as that of the second embodiment, except that, in this embodiment, the second end of the first annular portion 41 is formed with an inner fold 411, the inner fold 411 is connected to the valve port member 20, and the first annular portion 41 and the valve port member 20 are an integrally formed structure. In this embodiment, the first annular portion 41 and the valve port member 20 are integrally formed by stretching or stamping, which makes the assembly process more convenient and improves the assembly efficiency.

[0059] It should be noted that, in this embodiment, the first annular portion 41 and the valve mouth piece 20 are integrally formed by stretching or stamping, but this is not restrictive. In some other embodiments not shown in the figure, the first annular portion 41 and the valve mouth piece 20 can also be connected by welding.

[0060] like Fig. 9 In the fifth embodiment shown, a valve core assembly is also disclosed, and its structure is basically the same as that of the second embodiment, except that, in this embodiment, the reinforcement ring 40 also includes: a second annular portion 42. The second annular portion 42 is connected to the first annular portion 41, and a second step portion 43 matching the first step portion 13 is formed at the connection between the first annular portion 41 and the second annular portion 42. The second annular portion 42 is plugged into the first end of the limiting section 12, and the second step portion 43 abuts against the first step portion 13. The valve port member 20 is located inside the second annular portion 42 and is fixed by welding or interference fit. By providing the second annular portion 42, the limiting section 12 of the housing 10 can also be reinforced by the second annular portion 42, so that the limiting section 12 can be prevented from being deformed, and the valve core 30 can be prevented from being stuck, thereby improving the stability and reliability of the valve core assembly. In addition, through the limiting fit of the second step portion 43 and the first step portion 13, after the first pipeline 60 is assembled, the reinforcement member can be abutted against the first step portion 13 by the first pipeline 60, so as to facilitate subsequent welding and fixing.

[0061] In this embodiment, the second annular portion 42 and the first annular portion 41 are integrally formed by stretching or stamping. However, this is not restrictive, and in some other embodiments not shown in the figure, the first annular portion 41 and the second annular portion 42 can also be connected by welding.
