Mode for Carrying Out the Invention

[0026] Hereinafter, with reference to the drawings in the embodiments of the present application, the technical aspects in the embodiments of the present application will be described clearly and completely. However, it is obvious that the described embodiments are only some of the embodiments of the present application, not all of them. Hereinafter, the description of at least one exemplary embodiment is actually only illustrative and does not impose any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0027] As shown in FIGS. 1 to 17, an embodiment of the present application is a five-way valve including a main body portion 10 having a valve chamber 12, a first inlet 113, a second inlet 114, a first outlet 112, a second outlet 111, a third outlet 115, and a fourth outlet 116, a valve core 20 rotatably provided in the valve chamber 12 and having a first chamber 21, a second chamber 22, a third chamber 23, and a fourth chamber 24 provided at intervals, and a single motor actuator 30 drivingly connected to the valve core 20. The five-way valve is configured such that when the valve core 20 rotates, the first inlet 113 is communicated with the first outlet 112 through the first chamber 21, the second inlet 114 is communicated with the third outlet 115 through the third chamber 23, and the second outlet 111 and the fourth outlet 116 are blocked (first operating condition); the first inlet 113 is communicated with the first outlet 112 through the first chamber 21, the second inlet 114 is communicated with both the third outlet 115 and the fourth outlet 116 through the third chamber 23, and the second outlet 111 is blocked (second operating condition); the first inlet 113 is communicated with the first outlet 112 through the first chamber 21, the second inlet 114 is communicated with the fourth outlet 116 through the third chamber 23, and the third outlet 115 and the second outlet 111 are blocked (third operating condition); the second inlet 114 is communicated with the second outlet 111 through the second chamber 22, the first inlet 113 is communicated with the third outlet 115 through the fourth chamber 24, and the first outlet 112 and the fourth outlet 116 are blocked (fourth operating condition); the second inlet 114 is communicated with the second outlet 111 through the second chamber 22, the first inlet 113 is communicated with both the third outlet 115 and the fourth outlet 116 through the fourth chamber 24, and the first outlet 112 is blocked (fifth operating condition); the second inlet 114 is communicated with the second outlet 111 through the second chamber 22, the first inlet 113 is communicated with the fourth outlet 116 through the fourth chamber 24, and the first outlet 112 and the third outlet 115 are blocked (sixth operating condition). The five-way valve can be switched to any of these conditions.

[0028] In this embodiment, by driving and rotating one valve core 20 with one single-motor actuator 30, it is possible to realize the switching between a plurality of operating conditions of the five-way valve. Compared with the case in the prior art where the five-way valve drives two valve cores 20 respectively with two motors to switch the operating conditions of the five-way valve, this aspect reduces one set of motor and valve core 20, reduces the difficulty of production and manufacturing of the five-way valve, improves the mounting accuracy of the overall structure of the five-way valve, and reduces the manufacturing cost of the five-way valve.

[0029] Specifically, in the second operating condition, the single-motor actuator 30 drives the valve core 20 to rotate and hold at a plurality of different positions, and can adjust the ratio of the fluids output from the third outlet 115 and the fourth outlet 116. In the fifth operating condition, the single-motor actuator 30 drives the valve core 20 to rotate and hold at a plurality of different positions, and can adjust the ratio of the fluids output from the third outlet 115 and the fourth outlet 116.

[0030] In this embodiment, by driving and rotating one valve core 20 with one single-motor actuator 30, it is possible to adjust the flow rate of the outlets in the second and fifth operating conditions of the five-way valve. Compared with the case in the prior art where the five-way valve drives two valve cores 20 respectively with two motors to rotate and adjust the flow rate of the outlets of the five-way valve, this aspect reduces one set of motor and valve core 20, and reduces the difficulty of production and manufacturing and the manufacturing cost of the five-way valve.

[0031] As shown in FIGS. 8 and 9, the valve core 20 includes a first axial zone 251, a second axial zone 252, and a third axial zone 253 provided in order in the axial direction. The openings of the first chamber 21, the second chamber 22, the third chamber 23, and the fourth chamber 24 all face the inner wall of the valve chamber 12. The first chamber 21 includes a first main chamber 211 and a first sub-main chamber 212 that communicate with each other. The third chamber 23 includes a third main chamber 231 and a third sub-main chamber 232 that communicate with each other. The second chamber 22 includes a second main chamber 221 and a second sub-main chamber 222 that communicate with each other. The fourth chamber 24 includes a fourth main chamber 241 and a fourth sub-main chamber 242 that communicate with each other. Here, the first main chamber 211 and the second main chamber 221 are both located in the first axial zone 251. The first sub-main chamber 212, the third main chamber 231, the fourth main chamber 241, and the second sub-main chamber 222 are all located in the second axial zone 252. The third sub-main chamber 232 and the fourth sub-main chamber 242 are both provided in the third axial zone 253.

[0032] In this embodiment, a plurality of chambers for realizing the flow rate adjustment function and the working condition switching function of the five-way valve are provided on the same valve core 20, that is, the valve core 20 is divided into three layers: the first axial zone 251, the second axial zone 252, and the third axial zone 253, and a plurality of chambers having a flow relationship, that is, the first chamber 21, the second chamber 22, the third chamber 23, and the fourth chamber 24 are limited to the first axial zone 251, the second axial zone 252, and the third axial zone 253. In this way, the two mutually communicating segments in each chamber can be separated in the axial direction. Further, by rotating the valve core 20, the communication between different chambers and different inlets and outlets can be realized, and further, the purpose of switching the working conditions and adjusting the flow rate can be achieved. Compared with the case where the flow rate adjustment and the working condition switching of the five-way valve can be realized by rotating two valve cores in the prior art, this embodiment combines the functions of the two valve cores and then forms a new valve core 20, reducing the production cost of the five-way valve.

[0033] As shown in FIGS. 8 and 9, the valve core 20 includes, in the circumferential direction, a first sector zone 261, a second sector zone 262, a third sector zone 263, a fourth sector zone 264, a fifth sector zone 265, a sixth sector zone 266, a seventh sector zone 267, and an eighth sector zone 268 provided in sequence. Here, the first main chamber 211 is distributed in the first sector zone 261 and the second sector zone 262, the first main chamber 212 is distributed in the first sector zone 261 and the second sector zone 262, the third main chamber 231 is distributed in the third sector zone 263 and the fourth sector zone 264, the third main chamber 232 is distributed in the second sector zone 262 and the third sector zone 263, the second main chamber 221 is distributed in the seventh sector zone 267 and the eighth sector zone 268, the second main chamber 222 is distributed in the seventh sector zone 267 and the eighth sector zone 268, the fourth main chamber 241 is distributed in the fifth sector zone 265 and the sixth sector zone 266, and the fourth main chamber 242 is distributed in the sixth sector zone 266 and the seventh sector zone 267.

[0034] In this embodiment, a plurality of chambers for realizing the flow rate adjustment function and the working condition switching function of the five-way valve are provided on the same valve core 20. That is, the valve core 20 is divided into eight columns of the first sector zone 261, the second sector zone 262, the third sector zone 263, the fourth sector zone 264, the fifth sector zone 265, the sixth sector zone 266, the seventh sector zone 267, and the eighth sector zone 268, and a plurality of chambers having a flow relationship are limited within a plurality of sector zones. In this way, two communicating segments communicating with each other in each chamber can be separated in the radial direction. By rotating the valve core 20, the communication between different chambers and different inlets and outlets can be realized, and further, the purpose of switching the working conditions and adjusting the flow rate can be achieved. In this embodiment, compared with the case where the functions of the five-way valve are realized by rotating two valve cores in the prior art, since the functions of the two valve cores are combined to form a new valve core 20, the production cost of the five-way valve is reduced.

[0035] Specifically, in the axial direction of the valve core 20, the first axial zone 251, the second axial zone 252, and the third axial zone 253 have the same length. In the circumferential direction of the valve core 20, the first sector zone 261, the second sector zone 262, the third sector zone 263, the fourth sector zone 264, the fifth sector zone 265, the sixth sector zone 266, the seventh sector zone 267, and the eighth sector zone 268 have the same radian.

[0036] In this embodiment, by limiting the lengths of the first axial zone 251, the second axial zone 252, and the third axial zone 253 to be equal, it is limited that the communication areas between the chambers in each axial zone and the inlets and outlets of the main body 10 are all the same, and by making the communication areas between different axial zones and the inlets and outlets different, it is possible to prevent the flow rates of the inlets and outlets of the five-way valve from being different. By limiting the radians of the plurality of sector zones to be equal, it is ensured that the rotation angles corresponding to each sector zone of the valve core 20 are the same, and the reliability of the rotation of the valve core 20 is ensured.

[0037] As shown in FIG. 11, in the circumferential direction of the valve core 20, the opening angles of both the third outlet 115 and the fourth outlet 116 are both H1, the interval angle between the third outlet 115 and the fourth outlet 116 is H2, and the opening angles of both the third two main chambers 232 and the fourth two main chambers 242 are both H3, where H1 < H2 < H3. By doing so, since H3 > H2, when the valve core 20 rotates by a certain angle, it is ensured that the third outlet 115 and the fourth outlet 116 communicate simultaneously, and the performance of the five-way valve can be ensured.

[0038] As shown in FIGS. 6 and 7, the valve core 20 includes shaft sleeves 271, two circular end plates 272, a plurality of axial spacers 273, and a plurality of sector spacers 274. The two circular end plates 272 are provided in parallel and are both fixedly connected to the shaft sleeve 271. The two circular end plates 272 and the shaft sleeve 271 are all provided coaxially. Here, the plurality of axial spacers 273 and the plurality of sector spacers 274 are distributed in the space between the two circular end plates 272, and the space between the two circular end plates 272 is divided into a first chamber 21, a second chamber 22, a third chamber 23, and a fourth chamber 24. The single motor actuator 30 is drivingly connected to the shaft sleeve 271.

[0039] In this embodiment, the valve core 20 body is constituted by the shaft sleeve 271 and the circular end plates 272 at both ends. Further, by dividing the internal space of the valve core 20 body axially and radially by the plurality of axial spacers 273 and the plurality of sector spacers 274, the first chamber 21, the second chamber 22, the third chamber 23, and the fourth chamber 24 are formed to form the valve core 20. By doing so, all the main chambers communicating with each other in each chamber can be separated in both the axial and radial directions of the valve core 20, and at the same time, it is ensured that the first chamber 21, the second chamber 22, the third chamber 23, and the fourth chamber 24 can also be separated in the axial and radial directions of the valve core 20, ensuring the performance of the valve core 20.

[0040] Optionally, at least one of the circular end plates 272 has ribs to increase the structural strength of the valve core 20.

[0041] Specifically, each axial spacer 273 and each sector spacer 274 are both connected to the shaft sleeve 271, each sector spacer 274 is connected to at least two axial spacers 273, the third two main chambers 232 include a first sub-chamber C2 and a second sub-chamber C3 that communicate with each other, the fourth two main chambers 242 include a third sub-chamber C6 and a fourth sub-chamber C7 that communicate with each other, the valve core 20 further includes a first arc-shaped plate 281 and a second arc-shaped plate 282, and in the circumferential direction of the valve core 20, the first arc-shaped plate 281, the first sub-chamber C2, the second sub-chamber C3, the second arc-shaped plate 282, the third sub-chamber C6, and the fourth sub-chamber C7 are provided in sequence. Here, under the first operating condition, the first sub-chamber C2 communicates with the third outlet 115, the second arc-shaped plate 282 seals the fourth outlet 116, under the third operating condition, the second sub-chamber C3 communicates with the fourth outlet 116, the first arc-shaped plate 281 seals the third outlet 115, under the fourth operating condition, the third sub-chamber C6 communicates with the third outlet 115, the first arc-shaped plate 281 seals the fourth outlet 116, under the sixth operating condition, the fourth sub-chamber C7 communicates with the fourth outlet 116, and the second arc-shaped plate 282 seals the third outlet 115. In this embodiment, each axial spacer 273 and each sector spacer 274 are both connected to the shaft sleeve 271, which facilitates the installation and positioning of the axial spacer 273 and the sector spacer 274, and each sector spacer 274 is connected to at least two axial spacers 273, ensuring the restriction and support for the sector spacer 274 and ensuring the structural stability and reliability.

[0042] Optionally, a plurality of wave ribs extending along the circumferential direction are arranged in parallel on both the first arc-shaped plate 281 and the second arc-shaped plate 282, improving the structural strength and sealing effect of the valve core 20, and since the wave ribs are provided along the circumferential direction, the rotational resistance of the valve core 20 can be reduced.

[0043] As shown in FIGS. 4 to 7, the bottom wall of the valve chamber 12 has an arcuate groove 13, and the arcuate groove 13 is provided surrounding the axis of the valve core 20. The five-way valve further includes a limiting block 40, and the limiting block 40 is located on one side facing the bottom wall of the valve chamber 12 of the valve core 20, and the limiting block 40 is located within the arcuate groove 13.

[0044] Optionally, the limiting block 40 and the valve core 20 are of an integral structure, and injection molding can be used, thus reducing costs.

[0045] As shown in FIG. 16, the arcuate groove 13 has a first arcuate wall, a second arcuate wall, a first end wall and a second end wall. The limiting block 40 has a fan-shaped structure, and the limiting block 40 has a third arcuate wall, a fourth arcuate wall, a third end wall and a fourth end wall. Here, the first arcuate wall and the third arcuate wall are aligned, the second arcuate wall and the fourth arcuate wall are aligned, the first end wall is snap-fitted with the third end wall, and the second end wall is snap-fitted with the fourth end wall. In this way, the rotation of the limiting block 40 within the arcuate groove 13 realizes the limitation of the rotation of the valve core 20, and prevents the rotation angle of the valve core 20 from being too large or from not being accurately returned when returning.

[0046] Optionally, the valve core 20 has an engaging hole, and a support shaft is provided on the bottom wall of the valve chamber 12, and the support shaft penetrates into the engaging hole. The support shaft and the valve body 14 are of an integral structure.

[0047] Specifically, the valve core 20 has a first set position and a second set position. When the valve core 20 is in the first set position, the five-way valve is in the first operating condition, and the first end wall and the third end wall are separated. When the valve core 20 is in the second set position, the five-way valve is in the sixth operating condition, and the second end wall and the fourth end wall are separated. The rotation angle of the valve core 20 when the five-way valve is switched from the first operating condition to the sixth operating condition along the rotation direction is N, and the rotation angle range of the limiting block 40 in the arc-shaped groove 13 is larger than N. By doing so, the rotation angle range of the limiting block 40 in the arc-shaped groove 13 becomes larger than N. While restricting the rotation of the valve core 20 by the limiting block 40 and the arc-shaped groove 13, it does not affect the maximum rotation range of the valve core 20. That is, the rotation angle of the limiting block 40 in the arc-shaped groove 13 is larger than N, and the remaining amount is located at both ends of the rotation angle N, ensuring the reliability of the rotation of the valve core 20 of the five-way valve.

[0048] Specifically, the valve core 20 has a first set position. When the valve core 20 is in the first set position, the five-way valve is in the first operating condition. The valve core 20 has a preliminary rotation angle M. Here, when the valve core 20 rotates within the M angle range from the first set position along the rotation direction, the five-way valve is maintained in the first operating condition. When the valve core 20 rotates more than M angle from the first set position along the rotation direction, the five-way valve is switched to other operating conditions. By doing so, as shown in FIG. 13, when the valve core 20 is in the first set position, if a rotation or mounting error occurs in the valve core 20, it is possible to prevent a part of the third outlet 115 from being sealed by the first arc-shaped plate 281 and a part of the fourth outlet 116 from being opened by the second arc-shaped plate 282. Moreover, by doing so, by sufficiently providing the rotation angle and rotation time required for the five-way valve to switch from the first operating condition to the second operating condition, the valve core 20 maintains the five-way valve in the first operating condition within the preliminary rotation angle M, preventing a sudden switch of the operating condition from affecting the valve core 20 and preventing insufficient rotation.

[0049] Furthermore, the main body 10 includes a valve body 14 and a gasket 15. The valve body 14 has a valve chamber 12, the gasket 15 is provided in the valve chamber 12, and the first inlet 113, the second inlet 114, the first outlet 112, the second outlet 111, the third outlet 115, and the fourth outlet 116 are all provided in the gasket 15. Here, the first outlet 112, the first inlet 113, and the third outlet 115 are arranged side by side along the axial direction of the valve core 20, the second outlet 111, the second inlet 114, and the fourth outlet 116 are arranged side by side along the axial direction of the valve core 20, the first outlet 112 and the second outlet 111 are arranged side by side along the circumferential direction of the valve core 20, the first inlet 113 and the second inlet 114 are arranged side by side along the circumferential direction of the valve core 20, and the third outlet 115 and the fourth outlet 116 are arranged side by side along the circumferential direction of the valve core 20.

[0050] Specifically, as shown in FIG. 11, the included angle between both ends of the gasket 15 is 110°.

[0051] In this embodiment, as shown in FIGS. 10 to 16, the preliminary rotation angles are M = 8.5°, N = 225°, H1 = 28°, H2 = 62°, and H3 = 90°. Specifically, as shown in FIG. 13, the included angle between one end of the first arc-shaped plate 281 close to the third outlet 115 and the closer edge of the third outlet 115 is 8.5°, and the included angle between one end of the second arc-shaped plate 282 close to the fourth outlet 116 and the closer edge of the fourth outlet 116 is 8.5°. Specifically, the relationship between the plurality of main chambers and the plurality of chambers of the valve core 20 is as shown in FIG. 8.

[0052] Specifically, as shown in FIG. 8, the first one main chamber 211 includes an A1 sub-chamber and an A2 sub-chamber that communicate with each other, the first two main chamber 212 includes a B1 sub-chamber and a B2 sub-chamber that communicate with each other, the third one main chamber 231 includes a B3 sub-chamber and a B4 sub-chamber that communicate with each other, the fourth one main chamber 241 includes a B5 sub-chamber and a B6 sub-chamber that communicate with each other, the second one main chamber 221 includes an A7 sub-chamber and an A8 sub-chamber that communicate with each other, and the second two main chamber 222 includes a B7 sub-chamber and a B8 sub-chamber that communicate with each other.

[0053] As shown in FIGS. 11 to 16, the valve core 20 is in the first set position, and the rotation angle of the valve core 20 is 0°. At this time, the five-way valve is in the first operating condition. At this time, the third two main chamber 232 communicates with the third outlet 115, the fourth outlet 116 is sealed by the second arc-shaped plate 282, the first two main chamber 212 communicates with the first inlet 113, the third one main chamber 231 communicates with the second inlet 114, the first one main chamber 211 communicates with the first outlet 112, and the second outlet 111 does not communicate with other chambers and communicates with the closed chamber shown in FIG. 8. Therefore, the second outlet 111 has no communication relationship. The third two main chamber 232 communicates with the third one main chamber 231, and the first two main chamber 212 communicates with the first one main chamber 211. Therefore, at this time, the second inlet 114 communicates with the third outlet 115, and the first outlet 112 communicates with the first inlet 113.

[0054] The valve core 20 rotates counterclockwise by 22.5° with respect to the first set position, that is, the valve core 20 rotates by an angle of the preliminary rotation angle M + H1 / 2. At this time, the five-way valve is in the second working condition. The first arc-shaped plate 281 seals half of the third outlet 115. The second arc-shaped plate 282 on the other side also rotates by the same angle, communicating half of the fourth outlet 116 with the third two main chambers 232, and other communication relationships are not affected. At this time, the second inlet 114 communicates with the third outlet 115 and the fourth outlet 116 respectively, and the fluid inlet ratio of the second inlet 114 is 100%. The fluid ratios flowing out from the third outlet 115 and the fourth outlet 116 are 50% respectively. In this case, the ratio relationship of the fluids flowing out from the third outlet 115 and the fourth outlet 116 can be adjusted by rotating the rotation angle of the valve core 20. Specifically, the flow rate adjustment range is, that is, the rotation angle range of the valve core 20, that is, 8.5° to 36.5°. When the angle of the valve core 20 rotating counterclockwise is 8.5° to 22.5°, the occupancy ratio of the fluid flowing out from the third outlet 115 is larger than the occupancy ratio of the fluid flowing out from the fourth outlet 116. When the angle of the valve core 20 rotating counterclockwise is 22.5°, the fluids flowing out from the third outlet 115 and the fourth outlet 116 are of the same amount. When the angle of the valve core 20 rotating counterclockwise is 22.5° to 36.5°, the occupancy ratio of the fluid flowing out from the third outlet 115 is smaller than the ratio of the fluid flowing out from the fourth outlet 116. When the angle of the valve core 20 rotating counterclockwise is 36.5°, the third outlet 115 is completely sealed by the first arc-shaped plate 281, and the second arc-shaped plate 282 completely avoids the fourth outlet 116. At this time, the second inlet 114 communicates with the fourth outlet 116, and other communication relationships remain unchanged.

[0055] When the valve core 20 rotates counterclockwise by 45°, the five-way valve is in the third working condition. Similar to the case where the valve core 20 rotates counterclockwise by 36.5° as described above, the third outlet 115 is completely sealed by the first arc-shaped plate 281, the second arc-shaped plate 282 completely avoids the fourth outlet 116, and other communication relationships remain unchanged. At this time, the second inlet 114 communicates with the fourth outlet 116, and the first outlet 112 communicates with the first inlet 113.

[0056] When the valve core 20 rotates 180° counterclockwise, the five-way valve is in the fourth working condition. At this time, the fourth two main chambers 242 communicate with the third outlet 115, the fourth outlet 116 is sealed by the first arc-shaped plate 281, the fourth one main chamber 241 communicates with the first inlet 113, the second two main chambers 222 communicate with the second inlet 114, the second one main chamber 221 communicates with the second outlet 111, the first outlet 112 does not communicate with other chambers and communicates with the closed chamber shown in Fig. 8. Therefore, since the first outlet 112 has no communication relationship, at this time, the first inlet 113 communicates with the third outlet 115, and the second outlet 111 communicates with the second inlet 114.

[0057] When the valve core 20 rotates counterclockwise by 202.5°, the five-way valve is in the fifth operating condition. At this time, when combined with Fig. 11, it can be seen that the second arc-shaped plate 282 seals half of the third outlet 115, and the first arc-shaped plate 281 on the other side communicates the half of the fourth outlet 116 with the fourth second main chamber 242, and other communication relationships are not affected. At this time, the first inlet 113 communicates with the third outlet 115 and the fourth outlet 116 respectively, and the fluid inlet ratio of the first inlet 113 is 100%. The fluid ratios flowing out from the third outlet 115 and the fourth outlet 116 are 50% respectively. In this case, the ratio relationship of the fluids flowing out from the third outlet 115 and the fourth outlet 116 can be adjusted by rotating the rotation angle of the valve core 20. Specifically, the flow rate adjustment range is, that is, the rotation angle range of the valve core 20, that is, 188.5° - 216.5°. When the angle of the valve core 20 rotating counterclockwise is 188.5° - 202.5°, the occupancy ratio of the fluid flowing out from the third outlet 115 is smaller than the occupancy ratio of the fluid flowing out from the fourth outlet 116. When the angle of the valve core 20 rotating counterclockwise is 202.5°, the occupancy ratio of the fluid flowing out from the third outlet 115 is equal to the occupancy ratio of the fluid flowing out from the fourth outlet 116. When the angle of the valve core 20 rotating counterclockwise is 202.5° - 216.5°, the occupancy ratio of the fluid flowing out from the third outlet 115 is larger than the occupancy ratio of the fluid flowing out from the fourth outlet 116. When the angle of the valve core 20 rotating counterclockwise is 216.5°, the second arc-shaped plate 282 completely seals the third outlet 115, and the first arc-shaped plate 281 completely bypasses the fourth outlet 116. At this time, the first inlet 113 communicates with the fourth outlet 116, and the second outlet 111 communicates with the second inlet 114.

[0058] When the valve core 20 rotates counterclockwise by 225°, the five-way valve is in the sixth operating condition. Similar to the case when the valve core 20 rotates counterclockwise by 202.5° above, the third outlet 115 is completely sealed by the second arc-shaped plate 282, the first arc-shaped plate 281 completely bypasses the fourth outlet 116, and other communication relationships remain unchanged. At this time, the first inlet 113 communicates with the fourth outlet 116, and the second outlet 111 communicates with the second inlet 114.

[0059] Specifically, as shown in FIG. 16, when the five-way valve is in the first operating condition, the first end wall of the limiting block 40 and the third end wall of the arc-shaped groove 13 are separated, and there is a complementary angle between the second end wall of the limiting block 40 and the fourth end wall of the arc-shaped groove 13. The complementary angle is 5°, and the rotation angle of the limiting block 40 within the arc-shaped groove 13 is 230°. The purpose of setting the complementary angle is to facilitate the positioning of the valve core 20 in the initial position. After the valve core 20 is installed, first, the second end wall of the limiting block 40 on the valve core 20 can be brought into close contact with the fourth end wall of the arc-shaped groove 13. Then, the entire valve core 20 is rotated by 5° to ensure the accuracy of the position of the valve core 20 in the first operating mode. At the same time, when the five-way valve switches from the first operating mode to the sixth operating mode, the rotation angle required by the valve core 20 is 225°. By setting the complementary angle of 5°, after the valve core 20 rotates 225°, the second end wall of the limiting block 40 abuts against the fourth end wall of the arc-shaped groove 13, exerting a limiting effect on the valve core 20 to prevent the valve core 20 from continuously rotating. Moreover, in this way, every time the valve core 20 rotates and returns, the valve core 20 can be newly positioned by the method of adjusting the initial position of the valve core 20 during the above installation, ensuring the reliability of the five-way valve.

[0060] Optionally, in another embodiment, it is not necessary to set the complementary angle of 5°. When the valve core 20 is in the first set position, that is, when the rotation angle of the valve core 20 is 0°, the second end wall of the limiting block 40 abuts against the fourth end wall of the arc-shaped groove 13. In this way, the valve core 20 of the five-way valve can rotate 230°, that is, N = 230°, and it is easy to perform a return limit on the position of the valve core 20 in the initial position.

[0061] Specifically, due to different rotation angles of the valve core 20, the five-way valve further has a plurality of other communication operating conditions, all of which perform a four-way function and there is no ratio adjustment relationship, so they will not be listed one by one here.

[0062] As shown in FIGS. 4 and 10, the gasket 15 has an arc-shaped structure. The outer side of the gasket 15 is in close contact with the inner wall of the valve chamber 12, and the inner side of the gasket 15 is in close contact with the outer peripheral surface of the valve core 20. The main body 10 further includes two arc-shaped baffles 16 provided on the inner wall of the valve chamber 12. The two arc-shaped baffles 16 are respectively in contact with both ends in the circumferential direction of the gasket 15. On the side of the gasket 15 facing the inner wall of the valve chamber 12, a plurality of seal ribs are distributed in the axial and circumferential directions. In this way, the gasket 15 is restricted by the two arc-shaped baffles 16 to prevent the gasket 15 from rotating in the valve chamber 12. Moreover, a plurality of seal ribs are distributed in the axial and circumferential directions of the gasket 15, which can provide the replenishment of the elastic margin for sealing and improve the sealing reliability of the gasket 15. Specifically, the sealing reliability is improved by making the interval between the seal ribs extending along the axial direction in the gasket 15 smaller than the interval between the seal ribs extending along the circumferential direction of the gasket 15.

[0063] As shown in FIG. 3, the valve body 14 includes a base 141, a cylinder 142, and a plurality of reinforcing ribs 143. The cylinder 142 is connected to the base 141, and each reinforcing rib 143 is connected to both the base 141 and the outer wall of the cylinder 142. The cylinder 142 has a valve chamber 12, the base 141 has six flow paths, and the six flow paths are respectively communicated with a first inlet 113, a second inlet 114, a first outlet 112, a second outlet 111, a third outlet 115, and a fourth outlet 116. In this way, the six flow paths are respectively communicated with six inlets / outs, and further, by communicating with the six flow paths respectively through external connection pipes, the communication between the outside and the five-way valve is realized. By providing a plurality of reinforcing ribs 143, the overall structural strength of the valve body 14 is improved. At the same time, the gasket 15 is restricted by the two arc-shaped baffles 16 provided on the inner wall of the valve chamber 12, the communication between the flow path and the inlet / out is ensured, and the reliability of the five-way valve is ensured.

[0064] Optionally, the base 141 has a plurality of metal sleeves 144 to receive the pressing and tightening force of the bolt during the installation process, preventing the pressing and tightening force from concentrating on the valve body 14 and causing excessive force on the base 141 or the cylinder body 142 of the valve body 14, which could lead to cracking. The main body 10 further includes a flat gasket 19, which is in sealing connection with the base 141 and further seals an external connection pipe connected to the flow port at the position of the six flow ports.

[0065] Specifically, the main body 10 further includes a valve cover 17 and a sealing ring 18. The valve cover 17 is in sealing connection with the valve body 14, the valve cover 17 seals the opening of the valve chamber 12, the sealing ring 18 is provided in the concave groove of the valve cover 17, the five-way valve further includes a rotating shaft 50, a part of the rotating shaft 50 is fixed in the valve core 20, the rotating shaft 50 penetrates through the sealing ring 18, and the output shaft of the single-motor actuator 30 is in driving connection with the rotating shaft 50. In this way, the sealing between the valve body 14 and the valve cover 17 is realized by the sealing ring 18, preventing the fluid in the valve body 14 from flowing out from the valve cover 17 and improving the sealing performance of the five-way valve.

[0066] Optionally, the rotating shaft 50 penetrates into the shaft sleeve 271, the rotating shaft 50 is made of a metal material, and the valve core 20 is made of plastic.

[0067] As shown in FIG. 17, the single-motor actuator 30 includes a housing 31, a motor 32 provided in the housing 31, a gear assembly 33, and a control panel 34. The motor 32 is in driving connection with the input shaft of the gear assembly 33, the output shaft of the gear assembly 33 is in driving connection with the valve core 20, and the housing 31 is in fixed connection with the main body 10. In this way, the control device and the driving device are combined to form the single-motor actuator 30, reducing the processing and manufacturing costs of the five-way valve. Moreover, the single-motor actuator 30 mainly drives the valve core 20 to rotate by the gear assembly 33, has a simple structure, and reliable transmission.

[0068] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes are possible to the present application. Any modifications, equivalent substitutions, improvements, etc. made within the scope of the spirit and principle of the present application should all be included within the protection scope of the present application.
