[0050] In the embodiment, the rotation of the valve core 20 driven by the single motor actuator 30 can realize the conversion between the multiple working conditions of the five-way valve, compared with the prior art in which two motors are respectively used to drive two valve cores 20 to realize the conversion between the working conditions of the five-way valve, the present application reduces a set of motor and valve core 20, reduces the production and manufacturing difficulty of the five-way valve, improves the installation precision of the overall structure of the five-way valve, and reduces the manufacturing cost of the five-way valve.
[0051] Specifically, in the second working condition, the single motor actuator 30 can drive the valve core 20 to rotate to and remain at multiple different positions to adjust the proportion of the fluid output by the third outlet 115 and the fourth outlet 116; and in the fifth working condition, the single motor actuator 30 can drive the valve core 20 to rotate to and remain at multiple different positions to adjust the proportion of the fluid output by the third outlet 115 and the fourth outlet 116.
[0052] In the embodiment, the rotation of the valve core 20 driven by the single motor actuator 30 can adjust the outlet flow in the second and fifth working conditions of the five-way valve. Compared with the prior art in which two motors are respectively used to drive the rotation of two valve cores 20 to adjust the outlet flow of the five-way valve, the present scheme reduces a set of motor and valve core 20, and reduces the production difficulty and manufacturing cost of the five-way valve.
[0053] As shown in Figure 8 and Figure 9 , the valve core 20 includes a first axial zone 251, a second axial zone 252 and a third axial zone 253 arranged in sequence in the axial direction, and the openings of the first cavity 21, the second cavity 22, the third cavity 23 and the fourth cavity 24 are all directed to the inner wall of the valve chamber 12; the first cavity 21 includes a first primary cavity 211 and a first secondary cavity 212 which are in communication with each other, the third cavity 23 includes a third primary cavity 231 and a third secondary cavity 232 which are in communication with each other, the second cavity 22 includes a second primary cavity 221 and a second secondary cavity 222 which are in communication with each other, and the fourth cavity 24 includes a fourth primary cavity 241 and a fourth secondary cavity 242 which are in communication with each other; wherein the first primary cavity 211 and the second primary cavity 221 are both located in the first axial zone 251, the first secondary cavity 212, the third primary cavity 231, the fourth primary cavity 241 and the second secondary cavity 222 are all located in the second axial zone 252, and the third secondary cavity 232 and the fourth secondary cavity 242 are both arranged in the third axial zone 253.
[0054] In the embodiment, the multiple cavities for realizing the flow regulation function and the working condition conversion function of the five-way valve are arranged on the same valve core 20, i.e., the valve core 20 is divided into three layers of the first axial zone 251, the second axial zone 252 and the third axial zone 253, and the multiple cavities having a flow relationship, i.e., the first cavity 21, the second cavity 22, the third cavity 23 and the fourth cavity 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 communication sections in each cavity which are in communication with each other can be spaced apart in the axial direction, and the rotation of the valve core 20 can realize the communication between different cavities and different inlets and outlets, thereby achieving the purpose of working condition conversion and flow regulation. Compared with the prior art in which the rotation of two valve cores can realize the flow regulation and working condition conversion of the five-way valve, the present embodiment combines the functions of the two valve cores to form a new valve core 20, thereby reducing the production cost of the five-way valve.
[0055] As shown in Figure 8 and Figure 9As shown, the spool 20 includes, in the circumferential direction, a first sector 261, a second sector 262, a third sector 263, a fourth sector 264, a fifth sector 265, a sixth sector 266, a seventh sector 267 and an eighth sector 268 arranged in sequence; wherein the first primary cavity 211 is distributed in the first sector 261 and the second sector 262, the second primary cavity 212 is distributed in the first sector 261 and the second sector 262, the third primary cavity 231 is distributed in the third sector 263 and the fourth sector 264, the fourth primary cavity 232 is distributed in the second sector 262 and the third sector 263, the second primary cavity 221 is distributed in the seventh sector 267 and the eighth sector 268, the second primary cavity 222 is distributed in the seventh sector 267 and the eighth sector 268, the fourth primary cavity 241 is distributed in the fifth sector 265 and the sixth sector 266, and the fourth primary cavity 242 is distributed in the sixth sector 266 and the seventh sector 267.
[0056] In the present embodiment, the multiple cavities for realizing the five-way valve flow regulating function and the working condition conversion function are arranged on the same spool 20, i.e., the spool 20 is divided into eight rows of the first sector 261, the second sector 262, the third sector 263, the fourth sector 264, the fifth sector 265, the sixth sector 266, the seventh sector 267 and the eighth sector 268, and multiple cavities having a flow relationship are defined in multiple sectors. In this way, two mutually communicating communication sections in each cavity can be spaced apart in the radial direction, and the communication of different cavities and different inlets and outlets is realized by the rotation of the spool 20, thereby achieving the purpose of working condition conversion and flow regulation. Compared with the prior art in which two spools are rotated to realize the five-way valve function, the functions of the two spools are combined in the present embodiment to form a new spool 20, thereby reducing the production cost of the five-way valve.
[0057] Specifically, in the axial direction of the spool 20, the lengths of the first axial region 251, the second axial region 252 and the third axial region 253 are equal; and in the circumferential direction of the spool 20, the arc lengths of the first sector 261, the second sector 262, the third sector 263, the fourth sector 264, the fifth sector 265, the sixth sector 266, the seventh sector 267 and the eighth sector 268 are equal.
[0058] In the present embodiment, by defining that the lengths of the first axial region 251, the second axial region 252 and the third axial region 253 are equal, it is ensured that the communication areas of the cavities in each axial region and the inlets and outlets of the main body 10 are equal, thereby preventing the situation that the inlet and outlet flow rates of the five-way valve are different due to the unequal communication areas of different axial regions and inlets and outlets. By defining that the arc lengths of the multiple sectors are equal, it is ensured that the rotation angles of the spool 20 corresponding to each sector are equal, thereby ensuring the reliability of the rotation of the spool 20.
[0059] As shown in Figure 11 the third outlet 115 and the fourth outlet 116 are H2, and the opening angles of the third two main cavities 232 and the fourth two main cavities 242 are H3, wherein H1 < H2 < H3. By setting H3 > H2, it can be ensured that the third outlet 115 and the fourth outlet 116 can be simultaneously communicated when the valve core 20 rotates a certain angle, thereby ensuring the performance of the five-way valve.
[0060] As shown in Figure 6 and Figure 7 the valve core 20 comprises a shaft sleeve 271, two circular end plates 272, a plurality of axial partitions 273 and a plurality of sector partitions 274. The two circular end plates 272 are arranged in parallel and are fixedly connected with the shaft sleeve 271, and the two circular end plates 272 and the shaft sleeve 271 are coaxially arranged. The plurality of axial partitions 273 and the plurality of sector partitions 274 are distributed in the space between the two circular end plates 272 to divide the space between the two circular end plates 272 into the first cavity 21, the second cavity 22, the third cavity 23 and the fourth cavity 24. The single motor actuator 30 is drivingly connected with the shaft sleeve 271.
[0061] In the embodiment, the valve core 20 is formed by the shaft sleeve 271 and the two circular end plates 272 at the ends, and the first cavity 21, the second cavity 22, the third cavity 23 and the fourth cavity 24 are formed by the plurality of axial partitions 273 and the plurality of sector partitions 274 in the axial and radial directions. In this way, the mutual communication of the main cavities in each cavity can be ensured to be spaced apart in the axial and radial directions of the valve core 20, and the first cavity 21, the second cavity 22, the third cavity 23 and the fourth cavity 24 can also be spaced apart in the axial and radial directions of the valve core 20, thereby ensuring the performance of the valve core 20.
[0062] Optionally, at least one of the circular end plates 272 has a rib to increase the structural strength of the valve core 20.
[0063] Specifically, each axial partition plate 273 and each sector partition plate 274 are connected with the sleeve 271, and each sector partition plate 274 is connected with at least two axial partition plates 273; the third two main cavities 232 include a first sub-cavity C2 and a second sub-cavity C3 which are in communication with each other, and the fourth two main cavities 242 include a third sub-cavity C6 and a fourth sub-cavity C7 which are in communication with each other; the spool 20 further includes a first arc-shaped plate 281 and a second arc-shaped plate 282; in the circumferential direction of the spool 20, the first arc-shaped plate 281, the first sub-cavity C2, the second sub-cavity C3, the second arc-shaped plate 282, the third sub-cavity C6 and the fourth sub-cavity C7 are sequentially arranged; wherein in the first working condition, the first sub-cavity C2 and the third outlet 115 are in communication, and the second arc-shaped plate 282 blocks the fourth outlet 116; in the third working condition, the second sub-cavity C3 and the fourth outlet 116 are in communication, and the first arc-shaped plate 281 blocks the third outlet 115; in the fourth working condition, the third sub-cavity C6 and the third outlet 115 are in communication, and the first arc-shaped plate 281 blocks the fourth outlet 116; in the sixth working condition, the fourth sub-cavity C7 and the fourth outlet 116 are in communication, and the second arc-shaped plate 282 blocks the third outlet 115. In the embodiment, by connecting each axial partition plate 273 and each sector partition plate 274 with the sleeve 271, the installation and positioning of the axial partition plates 273 and the sector partition plates 274 are facilitated, and by connecting each sector partition plate 274 with at least two axial partition plates 273, the limiting and supporting of the sector partition plates 274 are ensured, and the stability and reliability of the structure are ensured.
[0064] Optionally, a plurality of wave-shaped ribs extending in the circumferential direction are arranged on the first arc-shaped plate 281 and the second arc-shaped plate 282, which improves the structural strength and sealing effect of the spool 20, and the wave-shaped ribs are arranged in the circumferential direction, so that the rotating resistance of the spool 20 can be reduced.
[0065] As shown in Figures 4 to 7 the bottom wall of the valve cavity 12 has an arc-shaped groove 13 which is arranged around the axis of the spool 20, and the five-way valve further includes a limiting block 40 which is located on the side of the spool 20 facing the bottom wall of the valve cavity 12, and the limiting block 40 is located in the arc-shaped groove 13.
[0066] Optionally, the limiting block 40 and the spool 20 are an integral structure which can be formed by injection molding, so that the cost can be reduced.
[0067] As shown in Figure 16As shown, the arc-shaped groove 13 has a first arc-shaped wall, a second arc-shaped wall, a first end wall and a second end wall, and the limiting block 40 has a third arc-shaped wall, a fourth arc-shaped wall, a third end wall and a fourth end wall; wherein the first arc-shaped wall and the third arc-shaped wall are matched, the second arc-shaped wall and the fourth arc-shaped wall are matched, the first end wall and the third end wall are in stop cooperation, and the second end wall and the fourth end wall are in stop cooperation. In this way, the rotation of the valve core 20 is limited by the rotation of the limiting block 40 in the arc-shaped groove 13, preventing the valve core 20 from rotating too much or not being able to reset accurately.
[0068] Optionally, the valve core 20 has a matching hole, and the bottom wall of the valve cavity 12 is provided with a support shaft which penetrates into the matching hole. The support shaft and the valve body 14 are in an integrated structure.
[0069] Specifically, the valve core 20 has a first set position and a second set position, the five-way valve is in the first working condition when the valve core 20 is in the first set position, and the first end wall and the third end wall are spaced apart; the five-way valve is in the sixth working condition when the valve core 20 is in the second set position, and the second end wall and the fourth end wall are spaced apart; the rotation angle of the valve core 20 is N when the five-way valve is switched from the first working condition to the sixth working condition in the rotation direction, and the rotation angle range of the limiting block 40 in the arc-shaped groove 13 is greater than N. In this way, the rotation angle range of the limiting block 40 in the arc-shaped groove 13 is greater than N, and the maximum rotation range of the valve core 20 is not affected when the rotation of the valve core 20 is limited by the limiting block 40 and the arc-shaped groove 13, that is, the rotation angle of the limiting block 40 in the arc-shaped groove 13 is greater than N and the excess is located at both ends of the rotation angle N, which ensures the reliability of the rotation of the valve core 20 of the five-way valve.
[0070] Specifically, the valve core 20 has a first set position, the five-way valve is in the first working condition when the valve core 20 is in the first set position, and the valve core 20 has a reserved rotation angle M; wherein the five-way valve remains in the first working condition when the valve core 20 rotates within the M angle range from the first set position in the rotation direction, and the five-way valve is switched to other working conditions when the valve core 20 rotates more than M angles from the first set position in the rotation direction. In this way, Figure 13 As shown, the valve core 20 is prevented from rotating or having installation errors at the first set position, so that a small part of the third outlet 115 is blocked by the first arc-shaped plate 281, and a small part of the fourth outlet 116 is opened by the second arc-shaped plate 282, and in this way, the five-way valve is given enough rotation angle and rotation time required for switching from the first working condition to the second working condition, so that the valve core 20 makes the five-way valve continue in the first working condition within the reserved rotation angle M, preventing sudden switching of the working condition from affecting the valve core 20 and causing the rotation to be out of place.
[0071] Further, the main body 10 comprises a valve body 14 having the valve cavity 12 and a sealing gasket 15 arranged in the valve cavity 12, 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 arranged in the sealing gasket 15; wherein the first outlet 112, the first inlet 113 and the third outlet 115 are arranged along the axial direction of the valve core 20, the second outlet 111, the second inlet 114 and the fourth outlet 116 are arranged along the axial direction of the valve core 20, the first outlet 112 and the second outlet 111 are arranged along the circumferential direction of the valve core 20, the first inlet 113 and the second inlet 114 are arranged along the circumferential direction of the valve core 20, the third outlet 115 and the fourth outlet 116 are arranged along the circumferential direction of the valve core 20.
[0072] Specifically, as shown in Figure 11 , the included angle between the two ends of the sealing gasket 15 is 110°.
[0073] In this embodiment, as shown in Figures 10 to 16 , the reserved rotation angle M = 8.5°, N = 225°, H1 = 28°, H2 = 62°, H3 = 90°, specifically, as shown in Figure 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 cavities and the plurality of cavity bodies of the valve core 20 is as shown in Figure 8 .
[0074] Specifically, as shown in Figure 8 , the first main cavity 211 comprises A1 and A2 sub-cavities in communication with each other, the second main cavity 212 comprises B1 and B2 sub-cavities in communication with each other, the third main cavity 231 comprises B3 and B4 sub-cavities in communication with each other, the fourth main cavity 241 comprises B5 and B6 sub-cavities in communication with each other, the second main cavity 221 comprises A7 and A8 sub-cavities in communication with each other, and the second main cavity 222 comprises B7 and B8 sub-cavities in communication with each other.
[0075] As shown in Figures 11 to 16As shown, 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 working condition, at this time, the third two main cavities 232 and the third outlet 115 are communicated, the fourth outlet 116 is blocked by the second arc-shaped plate 282, the first two main cavities 212 and the first inlet 113 are communicated, the third one main cavity 231 and the second inlet 114 are communicated, the first one main cavity 211 and the first outlet 112 are communicated, the second outlet 111 is communicated with the closed cavity shown in Figure 8, and is not communicated with other cavities, so the second outlet 111 has no communication relationship, the third two main cavities 232 and the third one main cavity 231 are communicated, the first two main cavities 212 and the first one main cavity 211 are communicated, so at this time, the second inlet 114 and the third outlet 115 are communicated, and the first outlet 112 and the first inlet 113 are communicated.
[0076] When the valve core 20 is counterclockwise rotated by 22.5° relative to the first set position, that is, the valve core 20 is rotated by an angle of M+H1 / 2 reserved rotation angle, at this time, the five-way valve is in the second working condition, the first arc-shaped plate 281 blocks half of the third outlet 115, and the second arc-shaped plate 282 on the other side also rotates the angle, and communicates half of the fourth outlet 116 with the third two main cavities 232, and other communication relationships are not affected. At this time, the second inlet 114 is communicated with the third outlet 115 and the fourth outlet 116 respectively, and the fluid entering proportion of the second inlet 114 is 100%, and the fluid outflow proportion of the third outlet 115 and the fourth outlet 116 is 50% respectively. In this case, the proportion relationship of the fluid outflow 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 adjustment range is the rotation angle range of the valve core 20, that is, 8.5° to 36.5°, when the valve core 20 is counterclockwise rotated by 8.5° to 22.5°, the proportion of the fluid outflow from the third outlet 115 is greater than that of the fluid outflow from the fourth outlet 116, when the valve core 20 is counterclockwise rotated by 22.5°, the fluid outflow from the third outlet 115 and the fluid outflow from the fourth outlet 116 are equal, when the valve core 20 is counterclockwise rotated by 22.5° to 36.5°, the proportion of the fluid outflow from the third outlet 115 is less than that of the fluid outflow from the fourth outlet 116, when the valve core 20 is counterclockwise rotated by 36.5°, the third outlet 115 is completely blocked 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 and the fourth outlet 116 are communicated, and other communication relationships are unchanged.
[0077] When the valve core 20 is counterclockwise rotated by 45°, the five-way valve is in the third working condition. As described above when the valve core 20 is counterclockwise rotated by 36.5°, the third outlet 115 is completely blocked by the first arc-shaped plate 281, the second arc-shaped plate 282 completely avoids the fourth outlet 116, and other connection relationships remain unchanged. At this time, the second inlet 114 and the fourth outlet 116 are connected, and the first outlet 112 and the first inlet 113 are connected.
[0078] When the valve core 20 is counterclockwise rotated by 180°, the five-way valve is in the fourth working condition. At this time, the fourth two main cavities 242 and the third outlet 115 are connected, the fourth outlet 116 is blocked by the first arc-shaped plate 281, the fourth one main cavity 241 and the first inlet 113 are connected, the second two main cavities 222 and the second inlet 114 are connected, the second one main cavity 221 and the second outlet 111 are connected, and the first outlet 112 and the closed cavity shown in Figure 8 are connected, not connected with other cavities. Therefore, the first outlet 112 has no connection relationship. At this time, the first inlet 113 and the third outlet 115 are connected, and the second outlet 111 and the second inlet 114 are connected.
[0079] When the valve core 20 is counterclockwise rotated by 202.5°, the five-way valve is in the fifth working condition. At this time, the first arc-shaped plate 281 and the second arc-shaped plate 282 are combined to block the third outlet 115, and the fourth one main cavity 241 and the fourth two main cavities 242 are connected. The first inlet 113 and the second inlet 114 are connected, and the second outlet 111 and the third outlet 115 are connected. The first outlet 112 is not connected with other cavities, and has no connection relationship. At this time, the first inlet 113 and the second inlet 114 are connected, and the second outlet 111 and the third outlet 115 are connected. Figure 11 It can be seen that the second arc-shaped plate 282 blocks half of the third outlet 115, and the first arc-shaped plate 281 on the other side connects half of the fourth outlet 116 with the fourth two main cavities 242, and other connection relationships are not affected. At this time, the first inlet 113 is connected with the third outlet 115 and the fourth outlet 116 respectively, and the fluid entering proportion of the first inlet 113 is 100%, and the fluid proportion flowing out of the third outlet 115 and the fourth outlet 116 is 50% respectively. In this case, the proportion relationship of the fluid flowing out of 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 adjustment range, i.e. the rotation angle range of the valve core 20, is 188.5° to 216.5°. When the valve core 20 is counterclockwise rotated by 188.5° to 202.5°, the proportion of the fluid flowing out of the third outlet 115 is less than the proportion of the fluid flowing out of the fourth outlet 116; when the valve core 20 is counterclockwise rotated by 202.5°, the proportion of the fluid flowing out of the third outlet 115 is equal to the proportion of the fluid flowing out of the fourth outlet 116; when the valve core 20 is counterclockwise rotated by 202.5° to 216.5°, the proportion of the fluid flowing out of the third outlet 115 is greater than the proportion of the fluid flowing out of the fourth outlet 116; when the valve core 20 is counterclockwise rotated by 216.5°, the second arc-shaped plate 282 completely blocks the third outlet 115, and the first arc-shaped plate 281 completely avoids the fourth outlet 116. At this time, the first inlet 113 and the fourth outlet 116 are connected, and the second outlet 111 and the second inlet 114 are connected.
[0080] When the valve core 20 rotates counterclockwise 225°, the five-way valve is in the sixth working condition, which is the same as when the valve core 20 rotates counterclockwise 202.5°. The third outlet 115 is completely blocked by the second arc plate 282, and the first arc plate 281 completely avoids the fourth outlet 116. Other connections remain unchanged. At this time, the first inlet 113 and the fourth outlet 116 are connected, and the second outlet 111 and the second inlet 114 are connected.
[0081] Specifically, such as Figure 16 As shown, when the five-way valve is in the first working condition, the first end wall of the limiting block 40 and the third end wall of the arc 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 groove 13. The complementary angle is 5°, and the rotation angle of the limiting block 40 in the arc groove 13 is 230°. The purpose of setting the complementary angle is to facilitate the positioning of the valve core 20 in its initial position. After installing the valve core 20, the second end wall of the upper limit block 40 and the fourth end wall of the arc groove 13 can be made to fit together first. Then, the valve core 20 can be rotated by 5° as a whole to ensure the accuracy of the valve core 20's position in the first working condition. At the same time, when the five-way valve switches from the first working condition to the sixth working condition, the valve core 20 needs to rotate by 225°. By setting the complementary angle of 5°, after the valve core 20 rotates 225°, the second end wall of the limit block 40 and the fourth end wall of the arc groove 13 abut against each other, which limits the valve core 20 and prevents it from continuing to rotate. Moreover, with this setting, after each rotation and reset of the valve core 20, the valve core 20 can be repositioned by adjusting the initial position of the valve core 20 during installation, ensuring the reliability of the five-way valve.
[0082] Optionally, in another embodiment, the 5° offset angle can be omitted. 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 and the fourth end wall of the arc groove 13 abut against each other. With this setting, the valve core 20 of the five-way valve can rotate to 230°, that is, N = 230°, which facilitates the reset and restriction of the position of the valve core 20 in the initial position.
[0083] Specifically, by rotating the valve core 20 at different angles, the five-way valve also has a variety of other connection conditions, but they all function as four-way valves and have no proportional adjustment relationship, so they will not be listed here.
[0084] like Figure 4 and Figure 10As shown, the sealing gasket 15 is arc-shaped, the outer side of the sealing gasket 15 is attached to the inner wall of the valve cavity 12, and the inner side of the sealing gasket 15 is attached to the outer circumferential surface of the valve core 20. The main body part 10 further comprises two arc-shaped baffles 16 arranged on the inner wall of the valve cavity 12, and the two arc-shaped baffles 16 respectively abut the two ends of the sealing gasket 15 in the circumferential direction. On the side of the sealing gasket 15 facing the inner wall of the valve cavity 12, the sealing gasket 15 is distributed with a plurality of sealing ribs in the axial and circumferential directions. In this way, the sealing gasket 15 is limited by the two arc-shaped baffles 16 to prevent the sealing gasket 15 from rotating in the valve cavity 12, and the sealing gasket 15 is distributed with a plurality of sealing ribs in the axial and circumferential directions to provide an elastic allowance for sealing and improve the sealing reliability of the sealing gasket 15. Specifically, the spacing between the sealing ribs of the sealing gasket 15 extending in the axial direction is smaller than the spacing between the sealing ribs of the sealing gasket 15 extending in the circumferential direction, so as to improve the sealing reliability.
[0085] As shown, Figure 3 The valve body 14 comprises 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 the outer wall of the base 141 and the cylinder 142. The cylinder 142 has the valve cavity 12, and the base 141 has six flow channels that are respectively communicated with 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. In this way, the six flow channels are respectively communicated with the six inlets and outlets, and then communicated with the six flow channels through external connecting pipes to realize the communication between the outside and the five-way valve. The plurality of reinforcing ribs 143 improve the overall structural strength of the valve body 14. At the same time, the two arc-shaped baffles 16 arranged on the inner wall of the valve cavity 12 limit the sealing gasket 15 to ensure the communication between the flow channels and the inlets and outlets, and ensure the reliability of the five-way valve.
[0086] Optionally, the base 141 has a plurality of metal sleeves 144 to withstand the downward locking force of the bolts during installation, preventing the downward locking force from being concentrated on the valve body 14 to cause the base 141 or the cylinder 142 of the valve body 14 to be excessively stressed and then cracked. The main body part 10 further comprises a flat gasket 19 that is sealingly connected to the base 141 to seal the external connecting pipes connected to the six flow channel openings.
[0087] Specifically, the main body 10 also includes a valve cover 17 and a sealing ring 18. The valve cover 17 and the valve body 14 are sealed together. The valve cover 17 blocks the opening of the valve cavity 12, and the sealing ring 18 is disposed in the groove of the valve cover 17. The five-way valve also includes a rotating shaft 50, a part of which is fixed inside the valve core 20. The rotating shaft 50 passes through the sealing ring 18, and the output shaft of the single motor actuator 30 is drivenly connected to the rotating shaft 50. This configuration uses the sealing ring 18 to achieve a seal between the valve body 14 and the valve cover 17, preventing fluid in the valve body 14 from flowing out of the valve cover 17 and improving the sealing performance of the five-way valve.
[0088] Optionally, the rotating shaft 50 is inserted into the bushing 271. The rotating shaft 50 is made of metal, and the valve core 20 is made of plastic.
[0089] like Figure 17 As shown, the single-motor actuator 30 includes a housing 31 and a motor 32, a gear assembly 33, and a control board 34 disposed within the housing 31. The input shafts of the motor 32 and the gear assembly 33 are drivenly connected, and the output shaft of the gear assembly 33 is drivenly connected to the valve core 20. The housing 31 and the main body 10 are fixedly connected. This configuration combines the control device and the drive device 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 through the gear assembly 33, resulting in a simple structure and reliable transmission.
[0090] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
