If the two fluid connectors are disassembled, before the two fluid connectors are pulled apart, the driving part has already achieved the closure of the fluid channel by the spherical valve core through the transmission assembly. Therefore, when the staff pulls apart the two fluid connectors, the problem of leakage of the two fluid connectors during the connection process is effectively avoided.

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] See also Figures 1 to 3 , is a fluid connector 100 provided by an embodiment of the present invention, and the fluid connector 100 can be used to cooperate with another fluid connector 100 to form a fluid connector. The fluid connector 100 includes a valve seat 200, a spherical valve core 300, and a transmission assembly 400.

[0056] The valve seat 200 is generally a columnar body, one end of the valve seat 200 is set as a docking end face 221, the valve seat 200 is provided with a fluid channel 230 along its longitudinal direction, and the fluid channel 230 forms a docking port on the docking end face 221. At the same time, the valve seat 200 is provided with a protruding driving portion 240 on the docking end face 221, and the valve seat 200 is provided with a guide groove 222 extending circumferentially on the docking end face 221 with the docking port as the center.

[0057] The spherical valve core 300 is roughly spherical, and a shaft portion 320 is provided on the opposite side of the spherical valve core 300. The spherical valve core 300 is arranged in the fluid channel 230. The shaft portion 320 is penetrated through the rotation hole of the side wall of the valve seat 200 and extends to the outside of the valve seat 200. The spherical valve core 300 is rotatably connected with the valve seat 200 through the shaft portion 320. During the rotation of the spherical valve core 300, the fluid channel 230 is closed or opened. The shaft portion 320 is connected to the spherical valve core 300 by clamping, or the two are connected in an integrated manner, or connected in other ways.

[0058] The transmission assembly 400 is movably located at a position corresponding to the guide groove 222 and is transmission-connected to the outer end of the rotating shaft portion 320. It should be noted that the transmission assembly 400 is movably located at a position corresponding to the guide groove 222, that is, the driving portion 240 of another fluid connector 100 extends into the guide groove 222 to be transmission-connected to the transmission assembly 400.

[0059] When one fluid connector 100 is connected with another fluid connector 100, the guide groove 222 is used to make way and guide the driving part 240, and the driving part 240 extends into the guide groove 222 and is connected to the transmission assembly 400; when the two fluid connectors 100 rotate relative to each other in the positive direction, the driving part 240 moves circumferentially along the guide groove 222, and drives the shaft part 320 to rotate forwardly through the transmission assembly 400, so as to drive the spherical valve core 300 to rotate from the closed position to the open position; and when the two fluid connectors 100 rotate relative to each other in the reverse direction, the driving part 240 moves circumferentially along the guide groove 222, and drives the shaft part 320 to rotate reversely through the transmission assembly 400, so as to drive the spherical valve core 300 to rotate from the open position to the closed position.

[0060] Specifically, when two fluid connectors 100 are assembled, first, the staff operates the two fluid connectors 100 to be connected relative to each other, that is, the butt end faces 221 of the two valve seats 200 are fitted together, the butt ports of the fluid channels 230 are connected, and the driving parts 240 of the two valve seats 200 extend into each other's guide grooves 222 respectively and are connected to the corresponding transmission components 400. Then, the staff operates the two fluid connectors 100 to rotate relative to each other in the positive direction, and the driving part 240 moves in the positive circumferential direction along the guide groove 222. Because the guide groove 222 is circumferentially extended with the butt port as the center, the butt ports of the two valve seats 200 always remain in a relative state. Among them, during the circumferential movement of the driving part 240 along the guide groove 222, the driving part 240 acts on the shaft part 320 through the transmission assembly 400 to drive the shaft part 320 to rotate forward, and the shaft part 320 drives the spherical valve core 300 to rotate forward synchronously, and the spherical valve core switches from a closed state to an open state to the fluid channel 230.

[0061] When the two fluid connectors 100 are disassembled, the staff operates the two fluid connectors 100 to rotate in opposite directions relative to each other, and the driving part 240 moves in opposite directions along the guide groove 222. During the circumferential movement of the driving part 240 along the guide groove 222, the driving part 240 acts on the rotating shaft part 320 through the transmission assembly 400 to drive the rotating shaft part 320 to rotate in the opposite direction, and the rotating shaft part 320 drives the spherical valve core 300 to rotate in the opposite direction synchronously, and the open state of the spherical valve core to the fluid channel 230 is switched to the closed state of the fluid channel 230. After the spherical valve core 300 is in the closed state to the fluid channel 230, the staff pulls one fluid connector 100 away from the other fluid connector 100.

[0062] As can be seen from the above, during the rotational assembly and disassembly of the two fluid connectors 100, the driving parts 240 of the two fluid connectors 100 act on each other's transmission components 400 during the rotation process, and each transmission component 400 drives the spherical valve core 300 to rotate through the rotating shaft part 320, and the spherical valve core 300 opens or closes the fluid channel 230 through rotation. With such a configuration, the staff does not need to perform additional operations to control the rotation of the spherical valve core 300 to open and close the fluid channel 230, thereby reducing the work intensity of the staff.

[0063] It should be emphasized that when the two fluid connectors 100 rotate relative to each other, the driving part 240 acts on the rotating shaft part 320 through the transmission assembly 400, so that the spherical valve core 300 realizes the opening and closing of the fluid channel 230 by rotating. In this way, if the two fluid connectors 100 are assembled, the spherical valve core 300 is driven to rotate after the two fluid connectors 100 are docked, which effectively ensures that the docking ports of the two fluid channels 230 are already in a sealed connection state during the opening of the spherical valve core 300, thereby avoiding the problem of leakage of the two fluid connectors 100 during the connection process. If the two fluid connectors 100 are disassembled, before the two fluid connectors 100 are pulled apart, the driving part 240 has already achieved the closure of the fluid channel 230 by the spherical valve core 300 through the transmission assembly 400. Therefore, when the staff pulls out the two fluid connectors 100, the problem of leakage of the two fluid connectors 100 during the connection process is effectively avoided.

[0064] In some embodiments, reference Figure 2 and Figure 3 The butt end surface 221 is provided with a protruding connection part 250, and the connection part 250 is provided with one or more. At the same time, the butt end surface 221 is also provided with a connection slot 223, and the connection slot 223 is circumferentially extended with the butt end port as the center, and the connection slot 223 and the connection part 250 are provided in equal numbers. In the circumferential direction around the butt end port, the connection slot 223 and the connection part 250 are alternately arranged in sequence. Among them, the guide slot 222 and the driving part 240 are located at the periphery of the connection slot 223, more precisely, the guide slot 222 and the driving part 240 are located at the edge area of ​​the butt end surface 221, but are not limited to being only provided at the edge area of ​​the butt end surface 221.

[0065] In specific applications, when two fluid connectors 100 are connected, the connecting parts 250 of the two valve seats 200 extend into each other's connecting slots 223. When the two fluid connectors 100 rotate relative to each other in the positive direction, the connecting part 250 is held in the connecting slot 223 by rotation, so that the two valve seats 200 are axially locked, thereby realizing the connection of the two fluid connectors 100. When the two fluid connectors 100 rotate relative to each other in the reverse direction, the connecting part 250 is released from the holding of the connecting slot 223 by rotation, so that the two valve seats 200 are released from the axial locking, thereby realizing the separation of the two fluid connectors 100.

[0066] As can be seen from the above, when the two fluid connectors 100 rotate relative to each other in the positive direction, the connecting portion 250 moves in the positive circumferential direction along the connecting slot 223, thereby realizing the connection of the two fluid connectors 100; and the driving portion 240 moves in the circumferential direction along the guide slot 222, thereby driving the spherical valve core 300 to rotate through the transmission assembly 400, thereby realizing the opening of the fluid channel 230. When the two fluid connectors 100 rotate relative to each other in the reverse direction, the connecting portion 250 moves in the reverse circumferential direction along the connecting slot 223, thereby releasing the restriction between the connecting portion 250 and the connecting slot 223; and the driving portion 240 moves in the reverse circumferential direction along the guide slot 222, thereby driving the spherical valve core 300 to rotate in the other direction through the transmission assembly 400, thereby realizing the closing of the fluid channel 230. As further explained above, during the installation and removal process of the two fluid connectors 100, the spherical valve core 300 automatically rotates along with the installation and removal of the fluid connectors 100, thereby realizing the automatic opening and closing of the fluid channel 230 by the spherical valve core 300.

[0067] In some embodiments, reference Figure 2 and Figure 3 When the two fluid connectors 100 rotate relative to each other in the forward direction, the driving part 240 is clamped in the guide groove 222 to axially clamp the two valve seats 200; when the two fluid connectors 100 rotate relative to each other in the reverse direction, the driving part 240 releases the clamping of the guide groove 222 to release the axial clamping of the two valve seats 200.

[0068] To further explain in detail, when the two fluid connectors 100 are connected to each other, the driving parts 240 of the two valve seats 200 extend into each other's guide grooves 222. When the two fluid connectors 100 rotate relative to each other in the positive direction, the driving part 240 is rotated and clamped in the guide groove 222, further axially clamping the two valve seats 200, thereby firmly connecting the two fluid connectors 100. When the two fluid connectors 100 rotate relative to each other in the reverse direction, the driving part 240 releases the clamping with the guide groove 222 by rotation, so that the two valve seats 200 release the axial clamping, so that the two fluid connectors 100 can be pulled apart.

[0069] In order to realize that the driving part 240 can drive the rotating shaft part 320 to rotate through the transmission assembly 400, in some embodiments, refer to Figures 2 to 4 The transmission assembly 400 includes a first transmission member 410 and a second transmission member 420, wherein the first transmission member 410 is substantially block-shaped, is located at a position corresponding to the guide groove 222, and is linearly slidably disposed on the valve seat 200, and the sliding direction is perpendicular to the longitudinal direction of the valve seat 200. A slot 411 is provided on one side of the first transmission member 410 close to the guide groove 222, and the length direction of the slot 411 is perpendicular to the sliding direction of the first transmission member 410. When the two fluid connectors 100 are connected in cooperation, the driving part 240 is plug-connected with the slot 411 and can slide relative to the first transmission member 410 along the length direction of the slot 411. The second transmission member 420 is transmission-connected with the shaft portion 320 and the first transmission member 410, and the first transmission member 410 drives the shaft portion 320 to rotate through the second transmission member 420 when sliding.

[0070] Specifically, when the two fluid connectors 100 are connected to each other, or when the two fluid connectors 100 are in a connected state, the driving part 240 is inserted into the slot 411 of the first transmission member 410 through the guide groove 222. When the two fluid connectors 100 rotate relative to each other in the forward or reverse direction, the driving part 240 pushes the first transmission member 410 to slide linearly. Among them, the length direction of the slot 411 is perpendicular to the sliding direction of the first transmission member 410. When the driving part 240 pushes the first transmission member 410 to slide, the driving part 240 slides along the length direction of the slot 411. Therefore, when the driving part 240 moves in an arc along the guide groove 222, it can also push the first transmission member 410 to slide, and the two do not interfere with each other. Because the first transmission member 410 is connected to the shaft portion 320 through the second transmission member 420, the first transmission member 410 acts on the shaft portion 320 through the second transmission member 420 during the sliding process, thereby driving the spherical valve core 300 to rotate, thereby realizing the closing and opening of the fluid channel 230.

[0071] It should be noted that the transmission assembly 400 adopts a first transmission member 410 that slides linearly. With this arrangement, when the two fluid connectors 100 rotate relative to each other, the circumferential movement is switched to linear movement, and the shaft portion 320 and the first transmission member 410 are located on the same side of the valve seat 200. In this way, the first transmission member 410 can drive the shaft portion 320 to rotate through the second transmission member 420 during the sliding process, thereby realizing the driving of the spherical valve core 300, and the solution can be implemented more conveniently.

[0072] In other possible embodiments, the transmission assembly 400 includes a driving arm (not shown in the figure), one end of the driving arm is connected to the rotating shaft portion 320, and the other end extends to the guide groove 222 along the radial direction of the rotating shaft portion 320. The driving portion 240 is inserted into the guide groove 222 and circumferentially abuts against the driving arm. Therefore, when the two fluid connectors 100 rotate relative to each other, the driving portion 240 acts on the driving arm circumferentially, thereby driving the rotating shaft portion 320 to rotate through the driving arm, thereby driving the spherical valve core 300 to rotate.

[0073] In a specific embodiment, referring to Figure 3 to Figure 4 , a first tooth portion 412 is provided on one side of the first transmission member 410 close to the rotating shaft portion 320, and a plurality of first tooth portions 412 are sequentially provided along the sliding direction of the first transmission member 410; meanwhile, the second transmission member 420 is roughly wheel-shaped, and the second transmission member 420 is sequentially provided with second tooth portions 421 in its circumferential direction, and the first tooth portion 412 meshes with the second tooth portion 421. Specifically, the first transmission member 410 is equivalent to a rack, and the second transmission member 420 is equivalent to a gear. When the driving part 240 pushes the first transmission member 410 to slide linearly, the first transmission member 410 drives the second transmission member 420 to rotate, and the second transmission member 420 drives the spherical valve core 300 to rotate synchronously through the rotating shaft portion 320, thereby realizing the opening or closing of the fluid channel 230.

[0074] Instead of the above-mentioned structure of the first transmission member 410 and the second transmission member 420, in another possible embodiment, the second transmission member 420 is a rod-shaped body, one end of the second transmission member 420 is rotatably connected to the first transmission member 410, and the other end is provided with a sliding hole 422, and the length direction of the sliding hole 422 is arranged in the same direction as the length direction of the second transmission member 420 (refer to Figure 8 A positioning plane is provided on the side of the rotating shaft portion 320, and the rotating shaft portion 320 is penetrated through the sliding hole 422, and the positioning plane of the rotating shaft portion 320 is arranged in contact with the inner wall of the sliding hole 422, thereby, the rotating shaft portion 320 and the second transmission member 420 are slidably arranged and circumferentially restricted.

[0075] Specifically, when the driving part 240 pushes the first transmission member 410 to slide linearly, the second transmission member 420 rotates relative to the first transmission member 410, and the shaft part 320 slides relative to the second transmission member 420 along the length direction of the sliding hole 422, thereby, the second transmission member 420 drives the shaft part 320 to rotate. When the shaft part 320 rotates, it drives the spherical valve core 300 to rotate synchronously, thereby realizing the opening and closing of the fluid channel 230.

[0076] In some embodiments, reference Figures 3 to 5The valve seat 200 includes a valve body 210 and a valve cover 220, wherein the valve body 210 is provided with a first channel 231 along its longitudinal direction and passes through both ends of the valve body 210. The valve cover 220 is provided with a second channel 232, the valve cover 220 is connected to one end of the valve body 210, and the first channel 231 is connected to the second channel 232 to form the above-mentioned fluid channel 230. The butt end surface 221 is the surface of the valve cover 220 away from the valve body 210, and the guide groove 222 is provided on the valve cover 220 and passes through the inner side of the valve cover 220. The spherical valve core 300 is provided in the first channel 231, and the rotating shaft portion 320 on the side of the spherical valve core 300 is rotatably connected to the side wall of the valve body 210 and extends to the outer side of the valve body 210. The driving part 240 is connected to the end of the valve body 210 close to the valve cover 220 and penetrates the valve cover 220 , or the driving part 240 is directly connected to the valve cover 220 .

[0077] Among them, refer to Figure 3 and Figure 6 A first sealing ring 700 is provided between the valve body 210 and the valve cover 220. The first sealing ring 700 is arranged around the side of the spherical valve core 300 close to the valve cover 220. Thus, the first sealing ring 700 makes the valve body 210 and the valve cover 220 sealed and connected. At the same time, a second sealing ring 800 is provided on the side of the valve cover 220 away from the valve body 210. When the two fluid connectors 100 are connected, the second sealing ring 600 is located between the two fluid connectors 100, thereby realizing the sealed connection of the two fluid connectors 100.

[0078] Further, refer to Figure 3 and Figure 6 The valve body 210 is provided with a boss portion 211 on the side with the rotating shaft portion 320. The boss portion 211 is arranged flush with the end surface of the valve body 210 close to the valve cover 220, and the rotating shaft portion 320 is located on the back side of the boss portion 211. The boss portion 211 is provided with a linearly extending and T-shaped sliding groove 212. The sliding groove 212 is arranged corresponding to the guide groove 222, that is, it is located on the side of the guide groove 222 close to the rotating shaft portion 320. The sliding groove 212 passes through the side of the boss portion 211 away from and close to the valve cover 220. The first transmission member 410 is slidably arranged in the sliding groove 212. A part of the valve cover 220 is located on the front side of the boss portion 211 and is arranged in contact with the side of the first transmission member 410 close to the valve cover 220. Therefore, the valve cover 220 is used to keep the first transmission member 410 slidingly arranged in the sliding groove 212.

[0079] It is understandable that the valve cover 220 is used to hide the part of the spherical valve core 300 exposed outside the valve body 210 to form a smooth butt end face 221, thereby ensuring the sealing between the two fluid connectors 100. In addition to ensuring the sealing between the spherical valve core 300 and the fluid channel 230 and the sealing between the two fluid connectors 100, the valve cover 220 also facilitates the first transmission member 410 to be slidably installed on the valve body 210 to be located at the corresponding position of the guide groove 222.

[0080] In some specific embodiments, referring to Figures 2 to 4 A limiting convex edge 241 is provided at the end of the driving portion 240, and a clearance hole 2221 is provided at the end of the guide groove 222. When the two fluid connectors 100 are connected to each other, the limiting convex edge 241 can extend into the inner side of the valve cover 220 through the clearance hole 2221; when one fluid connector 100 is connected with another fluid connector 100, the limiting convex edge 241 is pressed against the inner wall of the valve cover 220.

[0081] To further explain in detail, when the two fluid connectors 100 are connected to each other, the limiting convex edge 241 of the driving part 240 extends into the inner side of each other's valve cover 220 through the clearance hole 2221. When the two fluid connectors 100 rotate relative to each other in the positive direction, the limiting convex edge 241 is rotated and clamped on the inner wall of the valve cover 220, so that the two valve seats 200 are axially clamped, thereby realizing a stable connection between the two fluid connectors 100. When the two fluid connectors 100 rotate relative to each other in the reverse direction, the limiting convex edge 241 rotates back to the clearance hole 2221 to release the axial clamping with the valve cover 220, so that the two valve seats 200 are released from the axial clamping, so that the two fluid connectors 100 can be pulled apart.

[0082] In order to achieve a stable connection between two fluid connectors 100, in some embodiments, refer to Figures 3 to 5 , the butt end surface 221 is provided with a raised connection part 250, the connection part 250 is connected to the end of the valve body 210 close to the valve cover 220, and is arranged in the valve cover 220, or the connection part 250 is directly connected to the valve cover 220. There are one or more connection parts 250, and a limiting boss 251 is arranged at the end of each connection part 250; at the same time, the valve cover 220 is provided with a connection card slot 223, the connection card slot 223 is circumferentially extended with the second channel 232 as the center, and an avoidance hole 2231 for the limiting boss 251 to pass over is arranged at the end of the connection card slot 223. Among them, the connection card slots 223 and the connection parts 250 are arranged in equal numbers, and in the circumferential direction around the second channel 232, the connection card slots 223 and the connection parts 250 are arranged alternately in sequence.

[0083] To further explain in detail, when the two fluid connectors 100 are connected to each other, the limiting bosses 251 at the ends of the connecting parts 250 extend into the inner sides of the valve covers 220 of each other through the avoidance holes 2231. When the two fluid connectors 100 rotate relative to each other in the positive direction, the limiting bosses 251 are rotated and clamped on the inner wall of the valve cover 220, so that the two valve seats 200 are axially clamped, thereby realizing a stable connection between the two fluid connectors 100. When the two fluid connectors 100 rotate relative to each other in the reverse direction, the limiting bosses 251 rotate back to the avoidance holes 2231 to release the clamping with the inner wall of the valve cover 220, so that the two valve seats 200 are released from the axial clamping, so that the two fluid connectors 100 can be pulled apart.

[0084] In some embodiments, reference Figures 2 to 3 , the end of the driving part 240 is provided with a buffer sleeve or a rotating sleeve (equivalent to the above-mentioned limiting convex edge 241), and the driving part 240 is embedded in the slot 411 through the buffer sleeve or the rotating sleeve. It can be understood that if the end of the driving part 240 is provided with a buffer sleeve, the driving part 240 slides in the slot 411 through the buffer sleeve, so that the first transmission member 410 can be stably driven to slide linearly. If the end of the driving part 240 is provided with a rotating sleeve, the driving part 240 slides in the slot 411 through the rotating sleeve, so that the first transmission member 410 can be smoothly driven to slide linearly.

[0085] In some embodiments, reference Figure 3 and Figure 4 , the fluid connector 100 further includes a locking assembly 500. When the first transmission member 410 is at one end of the sliding groove 212, more specifically at a position corresponding to the yield hole 2221, the locking assembly 500 fixes the first transmission member 410 at this position. Therefore, when the two fluid connectors 100 are connected to each other, the driving part 240 is just inserted into the slot 411 of the first transmission member 410 through the guide groove 222; it should be noted that since the first transmission member 410 is restricted to this position, the position of the second transmission member 420 is effectively restricted, thereby keeping the spherical valve core 300 in a closed state with respect to the fluid channel 230. When the first transmission member 410 is at the other end of the sliding groove 212, the locking assembly 500 fixes the first transmission member 410 at this position, thereby keeping the driving portion 240 axially fixed with the valve cover 220, and the two fluid connectors 100 are firmly connected; at the same time, the locking assembly 500 limits the reverse rotation of the first transmission member 410, thereby limiting the rotation of the shaft portion 320, and the spherical valve core 300 remains in an open state with respect to the fluid channel 230.

[0086] Furthermore, the locking assembly 500 includes an operable latch 510 and an elastic member 520, wherein a mounting shell 213 is provided on the outer side of the valve body 210, the mounting shell 213 is located on the side of the boss portion 211 away from the valve cover 220, the latch 510 is slidably arranged on the inner side of the mounting shell 213 along the longitudinal direction of the valve seat 200, the latch 510 is provided with an operating portion, the operating portion is exposed on the outer side of the mounting shell 213, and the staff can push the latch 510 to slide longitudinally through the operating portion. At the same time, a first plug hole 413 and a second plug hole 414 are provided on the side of the first transmission member 410 away from the valve cover 220, when the spherical valve core 300 is in a closed state with respect to the fluid channel 230, the latch 510 is plugged and connected with the first plug hole 413, and when the spherical valve core 300 is in an open state with respect to the fluid channel 230, the latch 510 is plugged and connected with the second plug hole 414. The elastic member 520 is connected to the mounting shell 213 and the latch 510 , and is used to keep the latch 510 plug-in-connected with the first plug hole 413 or the second plug hole 414 .

[0087] Specifically, when the first transmission member 410 is at one end of the sliding groove 212, the first spherical valve core 300 is in a closed state with respect to the fluid channel 230, and the latch 510 is plugged and connected with the first plug hole 413 under the action of the elastic member 520. At this time, the latch 510 keeps the first transmission member 410 at this position, so that the spherical valve core 300 keeps the fluid channel 230 in a closed state. When the first transmission member 410 is at the other end of the sliding groove 212, the first spherical valve core 300 is in an open state with respect to the fluid channel 230, and the latch 510 is plugged and connected with the second plug hole 414 under the action of the elastic member 520. At this time, the latch 510 keeps the first transmission member 410 at this position, so that the spherical valve core 300 keeps the fluid channel 230 in an open state. If the spherical valve core 300 needs to be driven to switch from the open position to the closed position, or from the closed position to the open position, the staff pushes the latch 510 away from the valve cover 220 through the operating portion of the latch 510, thereby releasing the plug connection between the latch 510 and the first plug hole 413 or the second plug hole 414. After the restriction on the first transmission member 410 is released, the driving part 240 can push the first transmission member 410 to move forward or backward along the guide groove 222.

[0088] In some embodiments, reference Figure 4 and Figure 5The spherical valve core 300 is provided with a fluid through hole 310, and the fluid through hole 310 passes through both sides of the spherical valve core 300. When the spherical valve core 300 is in an open state with respect to the fluid channel 230, the two ends of the fluid through hole 310 are respectively facing the fluid channel 230, that is, the two ends of the fluid through hole 310 are connected with the fluid channel 230, so that the fluid channel 230 is in an open state. When the spherical valve core 300 is in a closed state with respect to the fluid channel 230, the two ends of the fluid through hole 310 are respectively facing the channel wall of the fluid channel 230, so that the fluid channel 230 is in a closed state. In other embodiments, the side wall of the spherical valve core 300 is provided with a notch, which can also replace the above-mentioned fluid channel 230.

[0089] In some embodiments, reference Figure 5 and Figure 7 The fluid connector 100 further includes a sealing ring 600. Specifically, a side portion of the rotating shaft portion 320 is provided with an annular groove, and the sealing ring 600 is engaged in the annular groove, so that the sealing ring 600 seals and connects the valve body 210 and the rotating shaft portion 320.

[0090] The present application discloses a fluid connector, including the above-mentioned fluid connector 100 , wherein two fluid connectors 100 are provided so as to be capable of mating connection.

[0091] It is understandable that, referring to Figures 1 to 3 , the fluid connector adopts the above-mentioned two types of fluid connectors 100. When assembling the fluid connector, first, the staff operates the two fluid connectors 100 to be connected relative to each other, that is, the docking end faces 221 of the two valve seats 200 are fitted, the docking ports of the fluid channel 230 are connected, and the driving parts 240 of the two valve seats 200 are respectively extended into each other's guide grooves 222, and connected with the corresponding transmission components 400. Then, the staff operates the two fluid connectors 100 to rotate relative to each other in the positive direction, and the driving part 240 moves circumferentially in the positive direction along the guide groove 222. Because the guide groove 222 is circumferentially extended with the docking port as the center, the docking ports of the two valve seats 200 always remain in a state of relative connection. Among them, during the circumferential movement of the driving part 240 along the guide groove 222, the driving part 240 acts on the shaft part 320 through the transmission assembly 400 to drive the shaft part 320 to rotate forward, and the shaft part 320 drives the spherical valve core 300 to rotate forward synchronously, and the spherical valve core switches the closed state of the fluid channel 230 to the open state of the fluid channel 230, thereby facilitating the assembly of the fluid connector.

[0092] When the fluid connector is disassembled, the staff operates the two fluid connectors 100 to rotate in opposite directions relative to each other, and the driving part 240 moves in opposite directions along the guide groove 222. During the circumferential movement of the driving part 240 along the guide groove 222, the driving part 240 acts on the rotating shaft part 320 through the transmission assembly 400 to drive the rotating shaft part 320 to rotate in the opposite direction, and the rotating shaft part 320 drives the spherical valve core 300 to rotate in the opposite direction synchronously, and the open state of the spherical valve core to the fluid channel 230 is switched to the closed state of the fluid channel 230. After the spherical valve core 300 is in the closed state to the fluid channel 230, the staff pulls one fluid connector 100 away from the other fluid connector 100, thereby facilitating the disassembly of the fluid connector.

[0093] The present application discloses a liquid cooling delivery system, comprising the above-mentioned fluid connector.

[0094] It is understandable that, referring to Figures 1 to 3 , the liquid cooling delivery system adopts the above-mentioned fluid connector. If the staff needs to repair the liquid cooling delivery system, during the installation and removal of the fluid connector, the driving parts 240 of the two fluid connectors 100 act on each other's transmission components 400 during the rotation process, and each transmission component 400 drives the spherical valve core 300 to rotate through the rotating shaft part 320, and the spherical valve core 300 opens or closes the fluid channel 230 through rotation. With this arrangement, the staff does not need to perform additional operations to control the rotation of the spherical valve core 300 to realize the opening and closing of the fluid channel 230, thereby facilitating the staff to carry out maintenance work.

[0095] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
