[0054] The application will be further described in detail below with reference to the accompanying drawings.

[0055] Please refer to Figures 1 to 3 A fluid connector 100 is provided for an embodiment of the application, which can be used to connect with another fluid connector 100 to form a fluid connector. The fluid connector 100 comprises a valve seat 200, a spherical valve core 300, and a transmission assembly 400.

[0056] The valve seat 200 is generally a cylindrical body, one end of the valve seat 200 is provided with a butt joint end face 221, and the valve seat 200 is provided with a fluid passage 230 along the longitudinal direction thereof, and the fluid passage 230 forms a butt joint port at the butt joint end face 221. At the same time, the valve seat 200 is provided with a protruding driving part 240 at the butt joint end face 221, and the valve seat 200 is provided with a guide groove 222 extending circumferentially with the butt joint port as the center at the butt joint end face 221.

[0057] The spherical valve core 300 is generally spherical, and the spherical valve core 300 is provided with a rotating shaft part 320 at opposite positions, the spherical valve core 300 is arranged in the fluid passage 230, the rotating shaft part 320 penetrates the rotating hole of the side wall of the valve seat 200 and extends to the outside of the valve seat 200, and the spherical valve core 300 is rotationally connected with the valve seat 200 through the rotating shaft part 320. The spherical valve core 300 closes or opens the fluid passage 230 during rotation. The rotating shaft part 320 is connected with the spherical valve core 300 in a clamping manner, or the two are integrally connected, or connected in other manners.

[0058] The transmission assembly 400 is movably arranged at the position corresponding to the guide groove 222 and is in transmission connection with the outer end of the rotating shaft part 320. It should be noted that the transmission assembly 400 is movably arranged at the position corresponding to the guide groove 222, that is, the driving part 240 of the other fluid connector 100 extends into the guide groove 222 to be in transmission connection with the transmission assembly 400.

[0059] When one fluid connector 100 is connected with another fluid connector 100, the guide groove 222 is used for the driving part 240 to make room and guide, the driving part 240 extends into the guide groove 222 and is in transmission connection with the transmission assembly 400; wherein, when two fluid connectors 100 are in positive relative rotation, the driving part 240 moves along the guide groove 222 in the circumferential direction, and drives the rotation shaft part 320 to rotate in the positive direction 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 two fluid connectors 100 are in reverse relative rotation, the driving part 240 moves along the guide groove 222 in the circumferential direction, and drives the rotation shaft part 320 to rotate in the reverse direction 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 connects two fluid connectors 100, that is, the abutting end faces 221 of the two valve seats 200 are in abutment, the abutting ports of the fluid channels 230 are in communication, and the driving parts 240 of the two valve seats 200 extend into the guide grooves 222 of each other, and are connected with the corresponding transmission assemblies 400. Then, the staff rotates two fluid connectors 100 in the positive direction, and the driving part 240 moves along the guide groove 222 in the positive circumferential direction. Because the guide groove 222 extends in the circumferential direction with the abutting port as the center, the abutting ports of the two valve seats 200 always remain in the connected state. During the movement of the driving part 240 along the guide groove 222 in the circumferential direction, the driving part 240 acts on the rotation shaft part 320 through the transmission assembly 400 to drive the rotation shaft part 320 to rotate in the positive direction, and the rotation shaft part 320 drives the spherical valve core 300 to rotate in the positive direction synchronously, and the spherical valve core switches the closed state of the fluid channel 230 to the open state of the fluid channel 230.

[0061] When two fluid connectors 100 are disassembled, the staff rotates two fluid connectors 100 in the reverse direction, and the driving part 240 moves along the guide groove 222 in the reverse circumferential direction. During the movement of the driving part 240 along the guide groove 222 in the circumferential direction, the driving part 240 acts on the rotation shaft part 320 through the transmission assembly 400 to drive the rotation shaft part 320 to rotate in the reverse direction, and the rotation shaft part 320 drives the spherical valve core 300 to rotate in the reverse direction synchronously, and the spherical valve core switches the open state of the fluid channel 230 to the closed state of the fluid channel 230. After the spherical valve core 300 is in the closed state of the fluid channel 230, the staff disconnects one fluid connector 100 from another fluid connector 100.

[0062] From the above, in the process of rotating assembly and disassembly, the driving part 240 of the two fluid connectors 100 acts on the transmission assembly 400 of each other in the rotating process, each transmission assembly 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. In this way, the staff does not need additional operation to control the rotation of the spherical valve core 300 to realize the opening and closing of the fluid channel 230, reducing the working strength 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 to make the spherical valve core 300 rotate to open and close the fluid channel 230. In this way, if the two fluid connectors 100 are assembled, the spherical valve core 300 is driven to rotate only after the two fluid connectors 100 are connected, which effectively ensures that the two fluid channels 230 are in a sealed connection state during the opening process of the spherical valve core 300, thereby avoiding the problem of liquid leakage during the connection of the two fluid connectors 100. If the two fluid connectors 100 are disassembled, the driving part 240 has realized the closure of the spherical valve core 300 to the fluid channel 230 through the transmission assembly 400 before the two fluid connectors 100 are pulled apart. Therefore, the staff effectively avoids the problem of liquid leakage during the connection of the two fluid connectors 100 when pulling apart the two fluid connectors 100.

[0064] In some embodiments, referring to Figure 2 and Figure 3 , the connecting part 250 is provided on the abutment end face 221, and the connecting part 250 is provided with one or more; at the same time, the abutment end face 221 is also provided with a connecting clamping groove 223, the connecting clamping groove 223 is arranged in a circumferential direction around the abutment port, and the connecting clamping groove 223 and the connecting part 250 are arranged in the same number. In the circumferential direction around the abutment port, the connecting clamping groove 223 and the connecting part 250 are arranged in turn and staggered. Among them, the guide groove 222 and the driving part 240 are located at the periphery of the connecting clamping groove 223, more correctly, the guide groove 222 and the driving part 240 are located at the edge area of the abutment end face 221, but it is not limited to be arranged only at the edge area of the abutment end face 221.

[0065] In the specific application, when the two fluid connectors 100 are connected, the connecting portions 250 of the two valve seats 200 respectively extend into the connecting clamping grooves 223 of each other. When the two fluid connectors 100 are connected in the positive direction, the connecting portions 250 are clamped in the connecting clamping grooves 223 by rotation, and thus the two valve seats 200 are axially clamped, thereby achieving the connection of the two fluid connectors 100. When the two fluid connectors 100 are connected in the reverse direction, the connecting portions 250 are released from the clamping of the connecting clamping grooves 223 by rotation, and thus the two valve seats 200 are released from the axial clamping, thereby achieving the disconnection of the two fluid connectors 100.

[0066] As can be seen from the above, when the two fluid connectors 100 are connected in the positive direction, the connecting portions 250 move in the positive direction along the connecting clamping grooves 223, thereby achieving the connection of the two fluid connectors 100; and the driving portions 240 move along the guide grooves 222, thereby driving the spherical valve core 300 to rotate through the transmission assembly 400, thereby achieving the opening of the fluid passage 230. When the two fluid connectors 100 are connected in the reverse direction, the connecting portions 250 move in the reverse direction along the connecting clamping grooves 223, thereby releasing the connecting portions 250 from the clamping of the connecting clamping grooves 223; and the driving portions 240 move in the reverse direction along the guide grooves 222, thereby driving the spherical valve core 300 to rotate in the other direction through the transmission assembly 400, thereby achieving the closing of the fluid passage 230. As can be further seen from the above, during the assembly and disassembly of the two fluid connectors 100, the spherical valve core 300 automatically rotates along with the assembly and disassembly of the fluid connectors 100, thereby achieving the automatic opening and closing of the fluid passage 230 by the spherical valve core 300.

[0067] In some embodiments, with reference to Figure 2 and Figure 3 When the two fluid connectors 100 are connected in the positive direction, the driving portions 240 are clamped in the guide grooves 222, thereby axially clamping the two valve seats 200; and when the two fluid connectors 100 are connected in the reverse direction, the driving portions 240 are released from the clamping of the guide grooves 222, thereby releasing the two valve seats 200 from the axial clamping.

[0068] Further specifically, when the two fluid connectors 100 are connected, the driving portions 240 of the two valve seats 200 respectively extend into the guide grooves 222 of each other. When the two fluid connectors 100 are connected in the positive direction, the driving portions 240 are clamped in the guide grooves 222 by rotation, and further axially clamping the two valve seats 200, thereby stably connecting the two fluid connectors 100. When the two fluid connectors 100 are connected in the reverse direction, the driving portions 240 are released from the clamping of the guide grooves 222 by rotation, and thus the two valve seats 200 are released from the axial clamping, thereby achieving the disconnection of the two fluid connectors 100.

[0069] To realize that the driving part 240 can drive the rotating shaft part 320 to rotate through the transmission assembly 400, in some embodiments, referring to Figures 2 to 4 The transmission assembly 400 includes a first transmission part 410 and a second transmission part 420. The first transmission part 410 is substantially in the shape of a block and is located at the position corresponding to the guide groove 222 and is linearly slidably arranged on the valve seat 200, and the sliding direction is perpendicular to the longitudinal direction of the valve seat 200. The side of the first transmission part 410 close to the guide groove 222 is provided with a slot 411, and the length direction of the slot 411 is perpendicular to the sliding direction of the first transmission part 410. When the two fluid connectors 100 are connected, the driving part 240 is insertedly connected with the slot 411 and can slide relative to the first transmission part 410 along the length direction of the slot 411. The second transmission part 420 is in transmission connection with the rotating shaft part 320 and the first transmission part 410. When the first transmission part 410 slides, the rotating shaft part 320 is driven to rotate through the second transmission part 420.

[0070] Specifically, when the two fluid connectors 100 are connected or in the connected state, the driving part 240 is inserted into the slot 411 of the first transmission part 410 through the guide groove 222. When the two fluid connectors 100 rotate forward or reversely, the driving part 240 pushes the first transmission part 410 to linearly slide. The length direction of the slot 411 is perpendicular to the sliding direction of the first transmission part 410. During the sliding of the first transmission part 410, the driving part 240 slides along the length direction of the slot 411, so that the driving part 240 can slide when moving along the circular arc of the guide groove 222, and the first transmission part 410 does not interfere with the driving part 240. Because the first transmission part 410 is in transmission connection with the rotating shaft part 320 through the second transmission part 420, the first transmission part 410 acts on the rotating shaft part 320 through the second transmission part 420 during the sliding process, so as to drive the spherical valve element 300 to rotate, thereby realizing the closing and opening of the fluid passage 230.

[0071] It should be noted that the first transmission part 410 of the transmission assembly 400 is linearly slidable. In this way, when the two fluid connectors 100 rotate relative to each other, the circumferential direction movement is switched to linear movement, and the rotating shaft part 320 and the first transmission part 410 are located on the same side of the valve seat 200. In this way, the first transmission part 410 can drive the rotating shaft part 320 to rotate through the second transmission part 420 during the sliding process, so as to realize the driving of the spherical valve element 300, and the scheme can be conveniently implemented.

[0072] In other possible embodiments, the transmission assembly 400 comprises a driving arm (not shown in the figure) which is connected to the rotating shaft portion 320 at one end and extends to the guide groove 222 in the radial direction of the rotating shaft portion 320. The driving portion 240 is arranged through the guide groove 222 and is in circumferential abutment with the driving arm. Thus, when the two fluid connectors 100 rotate relative to each other, the driving portion 240 acts on the driving arm in the circumferential direction, thereby driving the rotating shaft portion 320 to rotate through the driving arm, and further driving the spherical valve element 300 to rotate.

[0073] In a specific embodiment, referring to Figures 3 to 4 , the first transmission member 410 is provided with a first tooth portion 412 on the side close to the rotating shaft portion 320, and a plurality of first tooth portions 412 are arranged in sequence along the sliding direction of the first transmission member 410. Meanwhile, the second transmission member 420 is substantially in the shape of a wheel, and a plurality of second tooth portions 421 are arranged in sequence in the circumferential direction of the second transmission member 420. The first tooth portion 412 is in meshing engagement with the second tooth portion 421. Specifically, the first transmission member 410 corresponds to a rack, and the second transmission member 420 corresponds to a gear. When the driving portion 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 element 300 to rotate synchronously through the rotating shaft portion 320, thereby realizing the opening or closing of the fluid passage 230.

[0074] Instead of the structure of the first transmission member 410 and the second transmission member 420 described above, in another possible embodiment, the second transmission member 420 is in the shape of a rod, one end of the second transmission member 420 is rotationally connected to the first transmission member 410, and the other end is provided with a sliding hole 422, the length direction of the sliding hole 422 is arranged in the same direction as the length direction of the second transmission member 420 (see Figure 8 ). The side of the rotating shaft portion 320 is provided with a positioning plane, and the rotating shaft portion 320 is arranged through the sliding hole 422, and the positioning plane of the rotating shaft portion 320 is arranged in abutment with the inner wall of the sliding hole 422. Thus, the rotating shaft portion 320 is arranged in sliding connection with the second transmission member 420 and is arranged in circumferential limitation.

[0075] Specifically, when the driving portion 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 rotating shaft portion 320 slides relative to the second transmission member 420 along the length direction of the sliding hole 422. Thus, the second transmission member 420 drives the rotating shaft portion 320 to rotate. The rotating shaft portion 320 drives the spherical valve element 300 to rotate synchronously when rotating, thereby realizing the opening or closing of the fluid passage 230.

[0076] In some embodiments, referring to Figures 3 to 5The valve seat 200 includes a valve body 210 and a valve cover 220. The valve body 210 has a first channel 231 extending longitudinally through both ends. The valve cover 220 has a second channel 232 connected to one end of the valve body 210. The first channel 231 and the second channel 232 are connected to form the fluid channel 230. The mating end face 221 is the surface of the valve cover 220 away from the valve body 210. A guide groove 222 is provided on the valve cover 220 and extends through the inner side of the valve cover 220. A spherical valve core 300 is disposed in the first channel 231. 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 drive unit 240 is connected to the end of the valve body 210 near the valve cover 220 and passes through the valve cover 220, or the drive unit 240 is directly connected to the valve cover 220.

[0077] Among them, reference 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 spherical valve core 300 near the side of the valve cover 220, thereby sealing the valve body 210 and the valve cover 220. 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 800 is located between the two fluid connectors 100, thereby achieving a sealed connection between the two fluid connectors 100.

[0078] Furthermore, referring to Figure 3 and Figure 6 The valve body 210 has a boss 211 on the side with the pivot 320. The boss 211 is flush with the end face of the valve body 210 near the valve cover 220, and the pivot 320 is located on the back side of the boss 211. The boss 211 has a straight, T-shaped sliding groove 212, which is correspondingly located on the side of the guide groove 222 near the pivot 320. The sliding groove 212 passes through the side of the boss 211 away from and near the valve cover 220. The first transmission member 410 is slidably disposed in the sliding groove 212. A part of the valve cover 220 is located on the front side of the boss 211 and is fitted against the side of the first transmission member 410 near the valve cover 220. Thus, the valve cover 220 is used to keep the first transmission member 410 slidably disposed in the sliding groove 212.

[0079] It can be understood that the valve cover 220 is used to hide the exposed part of the spherical valve core 300 outside the valve body 210 to form a smooth butt joint end surface 221, so as to ensure 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 sliding installation of the first transmission member 410 on the valve body 210 to be located at the corresponding position of the guide groove 222.

[0080] In some embodiments, with reference to Figures 2 to 4 , the end of the driving part 240 is provided with a limiting protrusion 241, and the end of the guide groove 222 is provided with a let-out hole 2221. When the two fluid connectors 100 are connected, the limiting protrusion 241 can extend into the inside of the valve cover 220 through the let-out hole 2221; when one fluid connector 100 is connected with the other fluid connector 100, the limiting protrusion 241 abuts against the inner wall of the valve cover 220.

[0081] Further specifically, when the two fluid connectors 100 are connected, the limiting protrusion 241 of the driving part 240 extends into the inside of the valve cover 220 of the other through the let-out hole 2221. When the two fluid connectors 100 are rotated in the same direction, the limiting protrusion 241 is clamped on the inner wall of the valve cover 220 through rotation, so that the two valve seats 200 are axially clamped, thereby realizing the stable connection of the two fluid connectors 100. When the two fluid connectors 100 are rotated in opposite directions, the limiting protrusion 241 is rotated back to the let-out 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, thereby realizing the disconnection of the two fluid connectors 100.

[0082] In order to realize the stable connection of the two fluid connectors 100, in some embodiments, with reference to Figures 3 to 5 , the butt joint end surface 221 is provided with a protruding connecting part 250, the connecting part 250 is connected with the end of the valve body 210 close to the valve cover 220 and penetrates the valve cover 220, or the connecting part 250 is directly connected with the valve cover 220. The connecting part 250 is provided with one or more, and the end of each connecting part 250 is provided with a limiting boss 251; at the same time, the valve cover 220 is provided with a connecting clamping groove 223, the connecting clamping groove 223 is arranged in a circumferential direction around the second channel 232, and the end of the connecting clamping groove 223 is provided with a let-out hole 2231 for the limiting boss 251 to pass through. Among them, the connecting clamping groove 223 and the connecting part 250 are arranged in equal number, and in the circumferential direction around the second channel 232, the connecting clamping groove 223 and the connecting part 250 are arranged in turn.

[0083] Further specifically, when the two fluid connectors 100 are connected, the limiting bosses 251 at the ends of the connecting portions 250 respectively extend into the inner sides of the valve covers 220 through the avoiding hole positions 2231. When the two fluid connectors 100 are connected in the forward direction, the limiting bosses 251 are clamped on the inner walls of the valve covers 220 through rotation, so that the two valve seats 200 are axially clamped, and the two fluid connectors 100 are stably connected. When the two fluid connectors 100 are connected in the reverse direction, the limiting bosses 251 are released from the clamping on the inner walls of the valve covers 220 through rotation, so that the two valve seats 200 are released from the axial clamping, and the two fluid connectors 100 can be disconnected.

[0084] In some embodiments, referring to Figures 2 to 3 , the end of the driving portion 240 is provided with a buffer sleeve or a rotating sleeve (equivalent to the limiting boss 241 described above), and the driving portion 240 is embedded in the insertion slot 411 through the buffer sleeve or the rotating sleeve. It can be understood that if the end of the driving portion 240 is provided with a buffer sleeve, the driving portion 240 slides in the insertion slot 411 through the buffer sleeve, thereby stably driving the first transmission member 410 to slide linearly. If the end of the driving portion 240 is provided with a rotating sleeve, the driving portion 240 slides in the insertion slot 411 through the rotating sleeve, thereby smoothly driving the first transmission member 410 to slide linearly.

[0085] In some embodiments, referring to Figure 3 and Figure 4 , the fluid connector 100 further comprises 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 avoiding hole position 2221, the locking assembly 500 fixes the first transmission member 410 at the position. Therefore, when the two fluid connectors 100 are connected, the driving portion 240 is inserted into the insertion 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 limited at the position, the position of the second transmission member 420 is effectively limited, and the ball valve core 300 is kept in a closed state of the fluid passage 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 the position, so that the driving portion 240 is kept in an axially clamped state with the valve cover 220, and the two fluid connectors 100 are stably 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 rotating shaft portion 320, and the ball valve core 300 is kept in an open state of the fluid passage 230.

[0086] Further, the locking assembly 500 comprises a plug 510 and a resilient member 520, wherein the valve body 210 is provided with a mounting shell 213 on the side of the boss portion 211 away from the valve cover 220, the plug 510 is slidingly arranged on the inner side of the mounting shell 213 along the longitudinal direction of the valve seat 200, the plug 510 is provided with an operation portion exposed on the outer side of the mounting shell 213, and the worker can push the plug 510 to slide longitudinally through the operation portion. Meanwhile, the first transmission member 410 is provided with a first insertion hole 413 and a second insertion hole 414 on the side away from the valve cover 220, when the ball valve core 300 is in the closed state of the fluid passage 230, the plug 510 is connected with the first insertion hole 413 in plug-in connection, and when the ball valve core 300 is in the open state of the fluid passage 230, the plug 510 is connected with the second insertion hole 414 in plug-in connection. The resilient member 520 is connected with the mounting shell 213 and the plug 510, and is used to keep the plug 510 in plug-in connection with the first insertion hole 413 or the second insertion hole 414.

[0087] Specifically, when the first transmission member 410 is at one end of the sliding groove 212, the first ball valve core 300 is in the closed state of the fluid passage 230, and the plug 510 is connected with the first insertion hole 413 in plug-in connection under the action of the resilient member 520. At this time, the plug 510 keeps the first transmission member 410 in the position, so as to keep the ball valve core 300 in the closed state of the fluid passage 230. When the first transmission member 410 is at the other end of the sliding groove 212, the first ball valve core 300 is in the open state of the fluid passage 230, and the plug 510 is connected with the second insertion hole 414 in plug-in connection under the action of the resilient member 520. At this time, the plug 510 keeps the first transmission member 410 in the position, so as to keep the ball valve core 300 in the open state of the fluid passage 230. If it is needed to drive the ball valve core 300 to switch from the open position to the closed position, or from the closed position to the open position, the worker pushes the plug 510 to move away from the valve cover 220 through the operation portion of the plug 510, so as to release the plug-in connection between the plug 510 and the first insertion hole 413 or the second insertion hole 414. After the restriction on the first transmission member 410 is released, the driving portion 240 can push the first transmission member 410 to move forward or reversely along the guide groove 222.

[0088] In some embodiments, with reference to Figure 4 With Figure 5The fluid through hole 310 is provided with two ports, and the two ports of the fluid through hole 310 are respectively directed to the fluid channel 230 when the spherical valve core 300 is in the open state of the fluid channel 230, that is, the two ports of the fluid through hole 310 are communicated with the fluid channel 230, so that the fluid channel 230 is in the open state. When the spherical valve core 300 is in the closed state of the fluid channel 230, the two ports of the fluid through hole 310 are respectively directed to the channel wall of the fluid channel 230, so that the fluid channel 230 is in the closed state. In other embodiments, the side wall of the spherical valve core 300 is provided with a notch portion, which can also replace the above-mentioned fluid channel 230.

[0089] In some embodiments, with reference to Figure 5 With Figure 7 The fluid connector further comprises a sealing ring 600. Specifically, the side of the rotating shaft portion 320 is provided with an annular clamping groove, and the sealing ring 600 is clamped in the annular clamping groove, so that the sealing ring 600 seals the connection between the valve body 210 and the rotating shaft portion 320.

[0090] The application discloses a fluid connector comprising the above-mentioned fluid connector 100, and the fluid connector 100 is provided with two fluid connectors 100 to be connected in cooperation.

[0091] It can be understood that, with reference to Figures 1 to 3 The fluid connector adopts the above-mentioned two fluid connectors 100. When the fluid connector is assembled, first, the staff operates the two fluid connectors 100 to be connected, that is, the abutting end faces 221 of the two valve seats 200 are abutted, the abutting ports of the fluid channels 230 are communicated, the driving portions 240 of the two valve seats 200 respectively extend into the guide grooves 222 of each other and are connected with the corresponding transmission assemblies 400. Then, the staff operates the two fluid connectors 100 to be rotated in the same direction, and the driving portions 240 move in the circumferential direction along the guide grooves 222. Since the guide grooves 222 extend in the circumferential direction with the abutting ports as the center, the abutting ports of the two valve seats 200 always remain in the connected state. During the circumferential movement of the driving portions 240 along the guide grooves 222, the driving portions 240 act on the rotating shaft portions 320 through the transmission assemblies 400 to drive the rotating shaft portions 320 to rotate in the same direction, and the rotating shaft portions 320 drive the spherical valve cores 300 to rotate in the same direction, so that the closed state of the spherical valve cores 300 to the fluid channels 230 is switched to the open state of the fluid channels 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 reversely, and the driving part 240 moves reversely along the guide groove 222. During the 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 reversely, and the rotating shaft part 320 drives the spherical valve core 300 to rotate reversely synchronously, and the opening state of the spherical valve core 300 to the fluid passage 230 is switched to the closed state of the fluid passage 230. After the spherical valve core 300 is in the closed state to the fluid passage 230, the staff pulls one fluid connector 100 from the other fluid connector 100, thereby facilitating the disassembly of the fluid connector.

[0093] The application discloses a liquid cooling delivery system comprising the fluid connector.

[0094] It can be understood that the liquid cooling delivery system adopts the fluid connector. Figures 1 to 3 If the staff needs to maintain the liquid cooling delivery system, during the assembly and disassembly of the fluid connector, the driving part 240 of the two fluid connectors 100 acts on the transmission assembly 400 of each other during the rotation, and each transmission assembly 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 passage 230 through the rotation. In this way, 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 passage 230, thereby facilitating the maintenance work of the staff.

[0095] The technical means disclosed in the application is not limited to the technical means disclosed in the above embodiments, and also includes the technical solutions composed of any combination of the above technical features. It should be noted that, for ordinary skilled in the art, without departing from the principles of the application, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the application.
