[0042] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] Please refer to Figures 1 to 5. A detachable joint valve body provided in an embodiment of the present application includes a valve seat 10. A valve seat flow channel 11 is provided in the valve seat 10. The flow channel in the valve seat 10 can be a straight flow channel or a curved or bent flow channel. An active cavity for accommodating a valve core 20 is provided in the valve seat 10 or at one end thereof. That is, an active cavity can be provided inside the valve seat 10, or an active cavity can be provided at one end of the valve seat 10 by means of other structures, for example, at one end of the valve seat 10. A valve cover 14 is provided at the end. The end cavity between the valve cover 14 and the valve seat 10 is a movable cavity. A lever 141 is provided on the end of the valve cover 14 away from the valve seat 10. The valve cover 14 is provided with an arc-shaped hole 142. When the two valve bodies are docked, the levers 141 on the two valve bodies can be inserted into each other's arc-shaped holes 142 and connected to each other's valve cores 20. Therefore, when the two valve bodies are rotated in two opposite directions, the valve core 20 can rotate relative to the valve seat 10 to open or close the valve seat flow channel 11. In addition to the valve seat 10, the detachable joint valve body also includes a joint 30. A joint flow channel 31 is provided in the joint 30. One end of the joint 30 is provided with a valve seat connecting portion 32 that is detachably connected to the valve seat 10. The end of the joint 30 away from the valve seat connecting portion 32 is provided with a pipe connecting portion 33 adapted to the pipe. The joint flow channel 31 and the valve seat flow channel 11 are connected to each other. When the diameter of the pipeline meets the assembly size of the valve seat 10, the pipeline can be directly connected to the valve seat 10; when the diameter of the pipeline does not match the assembly size of the valve seat 10, the connector 30 can be connected to the valve seat 10 through the valve seat connecting part 32, and the pipeline can be connected to the pipeline connecting part 33 of the connector 30; in addition, a valve seat 10 can be selected to match multiple connectors 30. When the pipeline to be connected matches one of the connectors 30, this connector 30 can be connected to the valve seat 10. Therefore, by detachably connecting the connector 30 to the valve seat 10, the assembly operation of different pipelines can be met, thereby providing users with more options and facilitating the connection operation of the pipeline. In addition, the split structure of the valve body can not only reduce the manufacturing difficulty, but also reduce the maintenance cost of the valve body. For example, when the connector 30 is damaged, only the connector 30 can be replaced without replacing the entire valve body.

[0044] In some embodiments, the valve seat connecting portion 32 is threadedly connected to the valve seat 10. For example, when the valve seat 10 is provided with an external thread, the valve seat connecting portion 32 is provided with an internal thread that cooperates with the external thread. When the valve seat 10 is provided with an internal thread, the valve seat connecting portion 32 is provided with an external thread that cooperates with the internal thread. For example, one end of the valve seat flow channel 11 shown in Figure 2 has a valve seat internal thread interface 12, and the valve seat connecting portion 32 is threadedly connected to the valve seat internal thread interface 12, wherein the inner diameter of the valve seat internal thread interface 12 is preferably larger than the diameter of the valve seat flow channel 11, that is, the valve seat 10 is provided with a countersunk hole at one end facing the joint 30, the countersunk hole is coaxial with the valve seat flow channel 11, and the valve seat internal thread interface 12 is arranged on the inner side wall of the countersunk hole. To ensure the axial alignment of the connector 30 and the valve seat 10, as shown in FIG3 , the outer diameter of the connector 30 body is larger than the outer diameter of the valve seat connection portion 32. When the connector 30 body contacts the end surface of the valve seat 10, the valve seat connection portion 32 is fully threaded into the valve seat internal threaded interface 12. Furthermore, a seal 40 is provided between the valve seat connection portion 32 and the valve seat internal threaded interface 12. This seal 40 prevents leakage of the liquid conveyed within the valve seat 10. A sealing groove 13 can be provided within the counterbore. The sealing groove 13 can be located on the circumferential surface of the counterbore, i.e., the seal 40 is disposed within the sealing groove 13. When the valve seat connection portion 32 is threadedly connected to the valve seat internal threaded interface 12, the outer circumference of the end of the valve seat connection portion 32 passes through the seal 40. Alternatively, a sealing ring can be provided on the inner end surface of the counterbore. During connection, the end of the valve seat connection portion 32 can press the sealing ring against the inner end surface of the counterbore, thereby achieving a seal at the connection between the connector 30 and the valve seat 10.

[0045] In some embodiments, the pipe connection portion 33 includes an internal pipe thread interface provided inside the connector 30 and / or an external pipe thread interface provided outside the connector 30. That is, the internal pipe thread interface and the external pipe thread interface can be provided selectively or simultaneously. The pipe can be threadedly connected to the internal pipe thread interface or the external pipe thread interface, or after the connector 30 is removed from the valve seat 10, it can be threadedly connected to the valve seat internal thread interface 12. The internal pipe thread interface and the external pipe thread interface can improve the threaded connection adaptability of the connector 30 to the pipe.

[0046] In some embodiments, the external pipe thread interface is a stepped external thread interface, where the outer diameter of the stepped internal thread interface decreases from one end of the connector 30 near the valve seat 10 to the other end, i.e., the outer circumference of the connector 30 is provided with multiple threaded segments. The internal pipe thread interface is a stepped internal thread interface, where the inner diameter of the stepped internal thread interface increases from one end of the connector 30 near the valve seat 10 to the other end, i.e., the interior of the connector 30 is provided with multiple threaded segments. The pipe is selectively connected to one or more threaded segments on the stepped external thread interface, or to one or more threaded segments on the stepped internal thread interface. When the pipe diameter is small, a threaded segment with a smaller diameter can be selected for connection; when the pipe diameter is large, a threaded segment with a larger diameter can be selected for connection, to meet the requirements of pipes of different diameters.

[0047] In some embodiments, the pipe connection portion 33 includes an internal pipe threaded interface disposed within the connector 30 and an annular clamping portion disposed on the outer periphery of the connector 30. The annular clamping portion may be an annular protrusion and / or an annular clamping groove 21 disposed on the outer periphery of the connector 30. The pipe may be threadedly connected to the internal pipe threaded interface, or may be sleeved around the outer periphery of the connector 30 at the end away from the valve seat 10 and clamped to the annular clamping portion. When the outer periphery of the connector 30 is provided with an annular protrusion, the pipe should be made of an elastically deformable material, such as a plastic pipe. The pipe can be elastically deformed and tightened onto the connector 30 under the support of the annular protrusion. When the outer periphery of the connector 30 is provided with an annular clamping groove 21, a clamping ring that cooperates with the annular clamping groove 21 may be provided within the pipe.

[0048] In some embodiments, the outer circumference of the connector 30 is provided with multiple annular clamping portions, each of which has the same outer diameter. For example, multiple annular clamping portions of the same outer diameter may be provided at intervals around the outer circumference of the connector 30, or the outer diameters of the multiple annular clamping portions may decrease from one end of the connector 30 near the valve seat 10 to the other end. For example, multiple annular clamping portions of varying outer diameters may be provided directly on the outer circumference of the connector 30, or multiple cylindrical segments of varying outer diameters may be provided on the outer circumference of the connector 30, with the outer diameter of each cylindrical segment decreasing from one end of the connector 30 near the valve seat 10 to the other end, with each cylindrical segment provided with at least one annular clamping portion. During assembly, the pipe selectively engages with one or more of the annular clamping portions, and engaging the multiple annular clamping portions can improve the connection stability of the pipe.

[0049] In some embodiments, to facilitate screwing of the connector 30, at least a portion of the outer circumference of the connector 30 is provided with a flat surface. The at least portion of the outer circumference refers to a portion of the outer circumference of the connector 30 in the axial direction. For example, a flat surface can be provided on the outer circumference of a section of the connector 30 near the valve seat connection portion 32, and a pipe connection portion 33 can be provided on the outer circumference of a section of the connector 30 away from the valve seat 10. The flat surface is parallel to the central axis of the connector 30. For example, the connector 30 has a polygonal prism structure, preferably a hexagonal prism, and all six faces of the outer circumference of the hexagonal prism are flat surfaces. Alternatively, the connector 30 can have a cylindrical structure, and the outer circumference of the cylindrical structure has one or more flat surfaces.

[0050] In some embodiments, the center line of the joint flow channel 31 is staggered with the rotation axis of the valve core 20, that is, the center line of the joint flow channel 31 is not coaxial with the rotation axis of the valve core 20. Since the joint 30 is connected to the valve seat 10 and the pipeline is connected to the joint 30, when the valve seat 10 rotates, the pipeline will be driven to rotate around its own axis through the joint 30, thereby causing the pipeline to twist and deform, which will lead to the problem of loosening of the pipeline. Especially for the structure with a leakage sensor in the pipeline, the twisting and deformation of the pipeline may cause the leakage sensor to break or other problems of losing detection function. Therefore, in this embodiment, by staggering the center line of the joint flow channel 31 with the rotation axis of the valve core 20, the pipeline can be prevented from rotating and twisting around its own axis, and it will only cause the pipeline to rotate around the rotation axis of the valve core 20, that is, the pipeline will rotate eccentrically, but the twisting and deformation is small. In comparison, the damage to the pipeline is small.

[0051] The embodiment of the present application also provides a rotary gate valve, as shown in Figures 1 and 5. The rotary gate valve includes a valve core 20 and a detachable joint valve body provided by any of the above embodiments, and further includes a valve cover 14, a first sealing ring 50, a second sealing ring 60, and a locking member 70. The valve cover 14 is fixed to the end of the valve seat 10 away from the joint 30. The two can be radially fixedly connected by screws, or fixed by other means. An active cavity is formed between the inner end face of the valve cover 14 and the valve seat 10. The valve core 20 is located in the active cavity. The valve cover 14 has an arc-shaped hole 142. The two end faces of the valve core 20 are in contact with the valve seat 10 and the valve cover 14 through the first sealing ring 50 and the second sealing ring 60, respectively, to perform a sealing function. For the beneficial effects of the rotary gate valve, reference can be made to the above-mentioned detachable joint valve body, which will not be repeated here.

[0052] The embodiment of the present application also provides a pipeline connector, as shown in Figure 6, the pipeline connector includes: a first connecting end 100 and a second connecting end 200, the first connecting end 100 includes a first valve body and a first valve core, the first valve core is rotatably connected to the first valve body, and one end of the first valve body is provided with a first lever; the second connecting end 200 includes a second valve body and a second valve core, the second valve core is rotatably connected to the second valve body, and one end of the second valve body is provided with a second lever, the first lever is connected to the second valve core, and the second lever is connected to the first valve core. For example, referring to Figures 4 and 5, the end of the first lever can be inserted into the arc hole 142 of the second valve body to extend into the second valve core. The first valve body 100 and the second valve body 200 are connected to each other and can be rotated relative to each other, so as to drive the second valve core through the first lever, and the second valve core can be rotated through the second lever. The first valve body and the second valve body are both detachable valve bodies provided by any of the above embodiments, wherein the outer periphery of the ends of the first lever and the second lever are provided with a snap-fitting protrusion, which extends into the valve cover 14 and is connected to the valve core 20 and can be snapped into the valve cover 14 to avoid separation of the first connection end 100 and the second connection end 200 from each other. In addition, to facilitate locking the open and closed positions of the valve core 20, a valve core 20 opening locking hole and a valve core 20 closing locking hole can be provided on the valve core 20, and an axially movable locking member 70 is provided on the valve seat 10. When the valve core 20 rotates until the valve core 20 opening locking hole corresponds to the locking member 70, the head of the locking member 70 can extend into the valve core 20 opening locking hole to lock the position of the valve core 20; when the valve core 20 rotates until the valve core 20 closing locking hole corresponds to the locking member 70, the head of the locking member 70 can extend into the valve core 20 closing locking hole to lock the position of the valve core 20. Regarding the beneficial effects of the pipeline connector, reference can be made to the above-mentioned detachable joint valve body, which will not be repeated here.

[0053] The present application also provides a liquid cooling system including a pipe and the pipe connector provided in the above embodiment, wherein the pipe is connected to a joint 30, and further including a liquid pump that can transport liquid through the pipe and the pipe connector to achieve a cooling effect on the heat generating component.
