Fluid connectors and their connection ends

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 8, 2024, with application number 202420454081.1 and invention name “Fluid connector and its connection end”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of pipeline connection, and more specifically, to a connection end of a fluid connector and also to a fluid connector. Background Art

[0003] Liquid cooling technology is increasingly being used in applications such as servers. The fluid connectors used to connect pipes in liquid cooling technology are a key factor influencing its effectiveness. Current fluid connectors are all detachable, consisting of two detachable connector heads. However, connecting the two detachable connector heads in these existing detachable fluid connectors still presents significant operational inconveniences, particularly in applications involving small-diameter pipes and high-pressure environments.

[0004] During the process of realizing the present invention, the inventors discovered that there are at least the following problems in the prior art: the connection end of the detachable fluid connector is inconvenient to assemble and disassemble, which is a problem that those skilled in the art urgently need to solve.

[0005] Summary of the Invention

[0006] In view of this, the first purpose of the present application is to provide a fluid connector, which can solve the problem of inconvenient disassembly and assembly of the connecting end of a detachable fluid connector. The second purpose of the present application is to provide a fluid connector.

[0007] In order to achieve the above first purpose, this application provides the following technical solutions:

[0008] A connecting end of a fluid connector includes a valve seat and a valve core, the valve seat having a communicating channel, the valve core being rotatably connected relative to the valve seat and capable of rotating to close the communicating channel and to open the communicating channel, the valve seat forming a connecting head at one end of the communicating channel for connecting a pipeline, the center line of the connecting head and the rotation axis of the valve core being radially staggered.

[0009] During use, when the position of the valve core is constrained, it is necessary to rotate the valve seat to close or open the connecting channel. The rotation of the valve seat relative to the rotation axis will drive the corresponding end of the connected pipe to rotate in the working state. Since the center line of the connecting head and the rotation axis are radially staggered, the corresponding end of the pipe no longer rotates around its own center line, but rotates in an arc around the staggered rotation axis, and the rotation range is significantly increased. This allows the above-mentioned connecting end to be disassembled and assembled to simultaneously drive the valve core to rotate relative to the valve seat. At this time, the valve seat is operated to rotate. Since the rotation range of the connecting head and the pipe connected during installation is in an arc, the rotation range is increased and the rotation resistance is relatively small, making the valve core opening and closing operation convenient and simple. In summary, the connecting end of the fluid connector can effectively solve the problem of inconvenient disassembly and assembly of the connecting end of the detachable fluid connector.

[0010] In some technical solutions, the valve core has a connecting hole, and when the valve core rotates relative to the valve seat until the connecting hole and the corresponding end of the connecting channel are aligned, the connecting channel is opened; when the valve core rotates relative to the valve seat until the connecting hole and the corresponding end of the connecting channel are completely offset, the connecting channel is closed.

[0011] In some technical solutions, the connecting channel is linear; the connecting hole is a straight hole.

[0012] In some technical solutions, the communicating through hole is a cylindrical channel, the communicating hole is a cylindrical hole, and the diameters of the two are equal; when the valve core rotates relative to the valve seat until the communicating hole and one end of the communicating channel are aligned, the axis of the communicating hole and the axis of the communicating channel coincide; when the valve core rotates relative to the valve seat until the communicating hole and one end of the communicating channel are completely staggered, the physical part on the valve core closes the corresponding end of the communicating channel.

[0013] In some technical solutions, the valve core is disc-shaped and is arranged perpendicular to the connecting channel. The outer peripheral surface of the valve core is a cylindrical surface to rotatably cooperate with the cylindrical hole on the valve seat.

[0014] In some technical solutions, the center line of the connecting head and the rotation axis are arranged in parallel.

[0015] In some technical solutions, the valve seat is provided with a pushing portion on the side away from the connecting head for insertion into the valve core of the other connecting end; the valve core has a bayonet for cooperating with the pushing portion of the other connecting end; the valve seat has a card groove cooperating with the pushing portion of the other connecting end to constrain them to rotate with each other around the valve core rotation axis.

[0016] In some technical solutions, the valve seat includes a valve body and a valve cover, the valve body has the connecting head at one end and the valve cover at the other end, and the valve core is arranged between the valve cover and the valve body; the valve body is provided with the communicating channel, and the valve cover is provided with a docking channel, and the docking channel and the communicating channel are coaxially arranged and have equal diameters; the pushing part and the card groove are provided on the side surface of the valve cover away from the valve body, so that the pushing part can be rotatably engaged with the card groove of the other connecting end.

[0017] To achieve the second objective, the present application further provides a fluid connector comprising two connecting ends, each including a valve seat and a valve core, the valve seat having a communication channel, the valve core being movable relative to the valve seat and capable of closing and opening the communication channel; the valve seat of one connecting end being rotatably connected to the valve seat of the other connecting end about a rotation axis; the valve seat having a push portion extending into the valve core of the other connecting end, capable of pushing the valve core to open the communication channel on the valve seat when the valve seat rotates relative to the other valve seat about the rotation axis; one end of the communication channel forming a connecting head for connecting to a pipeline, the valve seat being radially offset from the centerline of the connecting head and the rotation axis. Similar to the above-mentioned connecting end, both are radially offset from the centerline of the connecting head and the rotation axis of the valve core. Since the above-mentioned connecting end has the above-mentioned technical effects, a fluid connector having the same connecting end should also have corresponding technical effects.

[0026] An embodiment of the present application discloses a fluid connector, which can solve the problem that the connection end of a detachable fluid connector is inconvenient to assemble and disassemble.

[0027] 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.

[0028] Please refer to Figures 1-4, Figure 1 is a structural schematic diagram of the connection end provided in an embodiment of the present application; Figure 2 is a cross-sectional structural schematic diagram of the connection end provided in an embodiment of the present application in a plug-in state; Figure 3 is a schematic diagram of the plug-in structure of the connection end provided in an embodiment of the present application; Figure 4 is a schematic diagram of the exploded structure of the connection end provided in an embodiment of the present application.

[0029] For example, Chinese patent publication number CN117249325A discloses a fluid connector structure comprising two mating connecting ends, each of which includes a valve seat and a valve core. The valve core is rotatably mounted within the valve seat, the valve core having a communication hole, and the valve seat having a communication channel. One end of the valve seat is used to connect to the other connecting end and has a push portion inserted into the valve core of the other connecting end. The other end of the valve seat is used to connect to a pipeline, and the communication channel connects the other connecting end and the pipeline. When the valve core rotates until the communication hole and the communication channel are aligned, the connection state is reached; when the valve core rotates until the communication hole and the communication channel are completely offset, the connection state is reached.

[0030] During use, when the two ends of a fluid connector rotate relative to each other, one end will always rotate relative to the other, pushing the valve core of each other to open. This rotation of the connector will also cause the connecting pipe to rotate. If the connecting pipe is not flexible, it will cause increased rotational resistance. In some actual application scenarios, there are many fluid connectors to operate, which makes the operator very tired during operation, resulting in significantly low operating efficiency.

[0031] In some embodiments, a connection end 100 of a fluid connector is provided to solve the problem of relatively large relative rotational resistance between the two connection ends 100 during actual installation, so as to further solve the problem of inconvenient assembly and disassembly between the connection ends 100 of a detachable fluid connector. The center line of the connection head 5 at one end of the connection end 100, which is used to connect the pipeline, is radially staggered with the rotation axis of the valve core 2 in the connection end 100. When the valve seat 1 of the connection end 100 is actively rotated so that the valve rotates and opens relative to the valve seat 1, the rotation of the valve seat 1 drives the connection pipeline to rotate. At this time, the connection pipeline no longer rotates around its own center line following the connection head 5, but rotates around the rotation axis of the valve. Because the two are radially staggered, the end of the connection pipeline rotates in an arc, has a larger range of motion, and is easier to rotate. The radial staggered setting refers to the staggering in the radial direction of the rotation axis, rather than a cross-coplanar setting. It is generally a parallel setting, of course, it can also present a certain non-coplanar intersection.

[0032] In some embodiments, based on some of the above embodiments, the connection end 100 includes a valve seat 1 and a valve core 2, wherein the valve seat 1 is provided with a communication channel 3, and the valve core 2 is rotatable relative to the valve seat 1 to achieve a rotational connection, and the valve core 2 can rotate relative to the valve seat 1 to close the communication channel 3 or to open the communication channel 3. Closing the communication channel 3, such as blocking one end or the middle of the communication channel 3, prevents fluid from flowing in from one end and out from the other end; while opening the communication channel 3 allows fluid to flow in from one end and out from the other end.

[0033] The valve seat 1 has a connecting head 5 formed at one end of the communication channel 3 for connecting to a pipeline. Generally, one end of the valve seat 1 is used to connect to another connecting end 100, while the other end is provided with the connecting head 5 for connecting to the pipeline. In the connected state, the communication channel 3 and the pipeline are in a communication relationship, and generally, the ends thereof are connected. The connecting head 5 can have a threaded structure or a clamping mechanism to facilitate connection to the pipeline. The specific connection method between the connecting head 5 and the pipeline can refer to the existing technology.

[0034] The center line of the connecting head 5 and the rotation axis of the valve core 2 are radially staggered. As mentioned above, during use, when the position of the valve core 2 is constrained, the valve seat 1 needs to be rotated to close or open the connecting channel 3. The rotation of the valve seat 1 relative to the rotation axis will drive the corresponding end of the connected pipe to rotate in the working state. Since the center line of the connecting head 5 and the rotation axis are radially staggered, the corresponding end of the pipe no longer rotates around its own center line, but rotates in an arc around the staggered rotation axis, and the rotation range is significantly increased. This allows the above-mentioned connecting end 100 to rotate the valve core 2 relative to the valve seat 1 during disassembly and assembly. Since the rotation range is in an arc, the rotation range is expanded and the rotation resistance is relatively small, making the opening and closing operation of the valve core 2 convenient and simple. In summary, the connecting end 100 of the fluid connector can effectively solve the problem of inconvenient disassembly and assembly of the connecting end 100 of the detachable fluid connector.

[0035] In some embodiments, based on some of the above embodiments, the valve core 2 can be provided with a connecting hole 4. When the valve core 2 rotates relative to the valve seat 1 until the connecting hole 4 and the corresponding end of the connecting channel 3 are aligned, the connecting channel is opened; when the valve core 2 rotates relative to the valve seat 1 until the connecting hole 4 and one end of the connecting channel 3 are completely offset, the connecting channel is closed. The connecting hole 4 is provided to better connect with the connecting channel 3 when opened, avoiding the formation of localized overly large pits. Generally, the cross-sectional shape and size of the connecting hole 4 and the connecting channel 3 are equal to achieve a better connection effect. Of course, some misalignment or differences in size and shape are also acceptable.

[0036] In practical applications, the cross-section of the communication hole 4 and / or the communication channel 3 can be circular or square. Because the communication hole 4 needs to rotate to two different positions that cannot overlap, the communication hole 4 is generally located on one side of the rotation axis of the valve core 2. The specific location can be set as needed.

[0037] In some embodiments, based on the above embodiments, the communication channel 3 can be linear, and the communication hole 4 can be a straight hole. This ensures that, during actual circulation, the fluid does not change direction when flowing through the connection end 100 into the pipeline or another connection end 100, thereby ensuring smoother fluid flow. In this case, the communication channel 3 and the communication hole 4 preferably have equal diameters and are of the same size.

[0038] In some embodiments, based on some of the above embodiments, the communicating through-hole can be a cylindrical channel, and the communicating hole 4 can be a cylindrical hole, with both having equal diameters. When the valve core 2 rotates relative to the valve seat 1 until the communicating hole 4 and one end of the communicating channel 3 are aligned, the axis of the communicating hole 4 and the axis of the communicating channel 3 coincide. It should be noted that in actual installation, the axis of the pipe connected to the connecting head 5 also coincides with the communicating through-hole. When the valve core 2 rotates relative to the valve seat 1 until the communicating hole 4 and one end of the communicating channel 3 are completely offset, the physical portion of the valve core 2 can be made to block the corresponding end of the communicating channel 3, thereby keeping that end of the communicating channel 3 in a closed state.

[0039] In some embodiments, based on some of the above embodiments, generally speaking, the valve core 2 can be disc-shaped and arranged perpendicular to the above-mentioned communication channel 3, so that the outer peripheral surface of the valve core 2 is a cylindrical surface to rotate with the cylindrical hole in the valve seat 1, thereby realizing a rotational connection between the valve seat 1 and the valve core 2. Of course, the relative rotational connection between the valve core 2 and the valve seat 1 can also be formed based on other structural constraints.

[0040] In some embodiments, based on the above embodiments, the centerline of the connector head 5 and the rotation axis can be arranged parallel to each other to achieve better staggering. It should be noted that, generally speaking, the greater the staggering distance between the connector head 5 and the rotation axis, the better. However, too large a distance will result in excessive bulk. The staggering distance between the centerline of the connector head 5 and the rotation axis can be equal to or slightly greater than the radius of the connecting channel, but should not exceed the diameter of the connecting channel.

[0041] In some embodiments, based on some of the above embodiments, the valve core 2 can have a bayonet 7 or other limiting portion to cooperate with the bayonet connection to another docking structure, such as another connecting end 100, so as to be fixed, so that when the valve seat 1 rotates, the valve core 2 will not rotate relative to the other docking structure, thereby driving the valve seat 1 to rotate, that is, the valve core 2 and the valve seat 1 can be rotated relative to each other to realize the opening of the valve core 2.

[0042] In some embodiments, based on the above embodiments, the valve seat 1 may be provided with a push portion 6 on a side away from the connecting head for insertion into the valve core 2 of the other connecting end 100. For example, the valve core 2 may have a bayonet 7 for mating with the push portion 6 of the other connecting end 100. The push portion 6 is inserted into the bayonet 7 of the valve core 2 of the other connecting end 100. The valve seat 1 may have a slot mating with the push portion 6 of the other connecting end 100, so as to constrain the valve core 2 to rotate around the rotation axis of the valve core 2.

[0043] Specifically, when there are two such connecting ends 100 for mating connection, for the convenience of description, the two connecting ends 100 are respectively referred to as the first connecting end and the second connecting end. The structure name corresponding to the first connecting end is incremented by the first, such as the first valve seat, the first valve core, the first pushing portion, etc., and the structure name corresponding to the second connecting end is incremented by the second, such as the second valve seat, the second valve core, the second pushing portion, etc. It should be noted that the first connecting end and the second connecting end can have exactly the same structure, or there can be some differences, such as being a male end and a female end, respectively.

[0044] When operating from the disconnected state to the connected state, the first and second connecting ends are first inserted into each other, that is, the first pushing portion is inserted into the second valve seat retaining groove, and the second pushing portion is inserted into the first valve seat retaining groove. The end of the first pushing portion extends into the retaining groove of the second valve core, and the end of the second pushing portion extends into the retaining groove of the first valve core to achieve torque transmission. Because the first pushing portion is inserted into the second valve seat retaining groove and the second pushing portion is inserted into the first valve seat retaining groove, the first and second valve seats are constrained to rotate relative to each other about the axis of the valve core. Specifically, this can be a rotational locking relationship, so that after rotation, they are axially locked.

[0045] Then, the first valve seat 1 and the second valve seat 1 are rotated relative to each other. At this time, at least one of the first valve seat 1 and the second valve seat 1 needs to rotate relative to the mounting base. For example, the first valve seat 100 rotates, and the pipe fixed to the first valve seat 1, with one end connected to the first valve seat 1, will rotate relative to the other end about the rotation axis. During the rotation, the first valve core 2 and the second valve seat 1 are relatively fixed and both rotate relative to the first valve seat 1, while the second valve core 2 and the first valve seat 1 are relatively fixed and both rotate relative to the second valve seat 1. When the second valve seat 1 rotates to the full position relative to the first valve seat 1, the first valve core 2 and the second valve core 2 are both in the open position.

[0046] In some embodiments, based on some of the above embodiments, in order to facilitate the installation of the valve core 2, the valve seat 1 can include a valve body 8 and a valve cover 9, and the valve body 8 has a connecting head at one end and a valve cover 9 at the other end, with the valve core 2 disposed between the valve cover 9 and the valve body 8; the valve body 8 is provided with a connecting channel 3, and the valve cover 9 is provided with a docking channel 10. The docking channel 10 and the connecting channel 3 are coaxially arranged and have the same diameter. When the valve core 2 rotates to open the connecting channel 3, the connecting hole 4 on the valve core 2 is connected between the connecting channel 3 and the docking channel 10. On the side surface of the valve cover 9 away from the valve body 8, a push portion 6 and a clamping groove 11 are provided, that is, the first valve cover is provided with a first clamping groove, and the second valve cover is provided with a second clamping groove, so that the push portion 6 can be rotatably engaged with the clamping groove 11 of the other connecting end 100. Generally speaking, the slot 11 has a perforated portion and a groove portion connected to the perforated portion and narrower than the perforated portion. The pushing portion 6 includes a handle and an enlarged head arranged at one end of the handle in the axial direction. The enlarged head can pass through the above-mentioned perforated portion until the handle enters the perforated portion, wherein the enlarged head protrudes from the handle, and then the pushing portion 6 rotates with the valve seat 1. At this time, the handle enters the groove, and the enlarged head cannot cross the groove due to its protruding handle setting, thereby realizing axial clamping.

[0047] Based on the connection end 100 provided in the above embodiment, the present application further provides a fluid connector, which includes any one of the connection ends 100 in the above embodiment. Since the fluid connector adopts the connection end 100 in the above embodiment, the beneficial effects of the fluid connector can be referred to the above embodiment.

[0048] In some embodiments, which may be based on or different from some of the above embodiments, a fluid connector is provided, comprising two connecting ends 100. Each connecting end 100 includes a valve seat 1 and a valve core 2. The valve seat 1 has a communication channel 3. The valve core 2 is movable relative to the valve seat 1 and can move between closing and opening the communication channel 3. In the two connecting ends 100, the valve seat 1 of one connecting end 100 is rotatably connected to the valve seat 1 of the other connecting end 100 about a rotation axis. The valve seat 1 has a push portion 6 that extends into the valve core 2 of the other connecting end 100. When the valve seat 1 rotates relative to the other valve seat 1 about the rotation axis, the push portion 6 can push the valve core 2 to open the communication channel 3 on the valve seat 1. One end of the communication channel 3 forms a connecting head 5 for connecting to a pipeline. The valve seat 1 is disposed such that the centerline of the connecting head 5 is offset from the rotation axis. The specific mating relationship between the valve core 2 and the valve seat 1 can refer to the above embodiments.

[0049] In some embodiments, based on some of the above embodiments, when the valve core 2 is pushed to rotate to open the connecting channel 3, the connecting channels 3 on the two valve seats 1 are coaxially arranged. Based on the above embodiments, when the valve core 2 is pushed to rotate to open the connecting channel 3, each connecting channel, each docking channel 10 and each connecting hole 4 can be coaxially arranged.

[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
