Description

Technical Field

[0001] This application relates to the field of pipe connection technology, and in particular to a joint assembly and a transformer. Background Technology

[0002] Existing pipelines are typically connected by flange joints to increase pipeline length and enable the transport of media such as liquids and gases.

[0003] However, existing flange butt joints are of a split structure, consisting of a pair of flange joints. During connection, one butt pipe connects to one flange joint, and the other butt pipe connects to the other flange joint. Then, the two flange joints are butt-jointed, and sealing gaskets, sealing rings, and other sealing components are installed on the flange faces where the two flange joints meet to achieve a seal. When the connection is not secure or the sealing components are damaged, the medium is prone to leakage, resulting in waste of the medium. Furthermore, the instantaneous leakage poses a risk of injuring bystanders and also pollutes the environment. Utility Model Content

[0004] The purpose of this application is to provide a joint assembly and a transformer, which aims to solve the problems of poor sealing performance and high leakage risk in existing flange butt joints.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, some embodiments of this application provide a connector assembly, including:

[0007] A pipe fitting, wherein the pipe fitting is an integrally formed structure, and the pipe fitting includes a first end and a second end;

[0008] A first fastener is connected to the first end and is used to fasten one end of the first pair of pipes to the first end;

[0009] The second fastener is connected to the second end and is used to fasten one end of the second pair of pipes to the second end.

[0010] The connector assembly provided in this application embodiment can firmly fix the butt pipe to the pipe connector by fasteners at both ends of the pipe connector. By using an integrally molded pipe connector structure, that is, the entire connector is a complete component, the mating surface and sealing element of the traditional flange butt joint are eliminated, avoiding leakage problems caused by poor mating or damage to the sealing element, thereby improving the sealing effect and reducing the risk of media leakage.

[0011] In some embodiments, the first fastener is a clamp or a nut, and / or the second fastener is a clamp or a nut.

[0012] In some embodiments, the inner wall of the clamp is provided with an annular groove structure.

[0013] In some embodiments, the clamp includes a first clamp body and a second clamp body that are joined together, and the first clamp body and the second clamp body are capable of opening or closing.

[0014] In some embodiments, one side of the first hoop is rotatably connected to one side of the second hoop, and the other side of the first hoop is connected to the other side of the second hoop by a third fastener.

[0015] In some embodiments, the third fastener is a bolt, which is used to connect the first hoop to the other side of the second hoop via a torque wrench.

[0016] In some embodiments, the axial length of the clamp is 90–110 mm.

[0017] In some embodiments, the outer walls of the first end and the second end are respectively provided with protruding structures around the perimeter.

[0018] In some embodiments, the pipe fitting is a straight pipe fitting or a bend pipe fitting.

[0019] Secondly, some embodiments of this application also provide a transformer, including: a transformer body and a connector assembly as described in the above embodiments, wherein the transformer body is provided with an oil pipeline, the oil pipeline including a first pair of connecting pipes and a second pair of connecting pipes, the first pair of connecting pipes and the second pair of connecting pipes being connected through the connector assembly.

[0020] The transformer provided in this application embodiment, through the joint assembly of the above embodiment, can improve the sealing performance of the pipeline connection, reduce the risk of oil leakage, and since the joint assembly does not need to be equipped with a seal, it can also prevent foreign objects caused by seal damage from entering the transformer through the pipeline, thereby improving safety.

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0035] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0038] The existing flange joint is a split structure, consisting of two independent flange joints connected by bolts. A sealing gasket or sealing ring is installed between the flange faces of the flange joints to achieve a seal. When the two flange joints become loose or the seal is damaged, the transmitted medium will leak. The leak may also pose a risk of injuring bystanders and pollute the environment.

[0039] To address the aforementioned technical problems, this application provides a novel connector assembly. By replacing the traditional flange butt joint with an integrally molded pipe joint structure, the mating surface and sealing elements of the traditional flange butt joint are eliminated, avoiding leakage problems caused by loosening of the joint or damage to the sealing elements. This improves the sealing effect and reduces the risk of leakage of the transmission medium.

[0040] In some embodiments, refer to Figure 1 As shown, this application provides a connector assembly, including: a pipe connector 1, a first fastener, and a second fastener. The pipe connector 1 is an integrally formed structure, including a first end 101 and a second end 102; the first fastener is connected to the first end 101 and is used to fasten one end of a first pair of connecting pipes to the first end 101; the second fastener is connected to the second end 102 and is used to fasten one end of a second pair of connecting pipes to the second end 102.

[0041] It is understood that, unlike existing split flange butt joints, the pipe joint 1 provided in this embodiment is a one-piece molded structure, meaning the entire joint is a single, complete component. There are no detachable mating surfaces like on flange butt joints, allowing the medium to be directly transmitted through the internal channel of the pipe joint 1 without relying on external seals. This design reduces the risk of leakage, improves safety, and minimizes environmental pollution.

[0042] The two ends of the pipe connector 1 are referred to as the first end 101 and the second end 102, respectively. Each end is used to connect a connecting pipe; that is, one connecting pipe is connected to the first end 101 of the pipe connector 1, and the other connecting pipe is connected to the second end 102. Furthermore, to ensure that the connecting pipes are securely connected to both ends of the pipe connector 1, this embodiment can use matching fasteners. Specifically, a first fastener is used to fasten one end of the first connecting pipe to the first end 101, and a second fastener is used to fasten one end of the second connecting pipe to the second end 102. By directly fixing the connecting pipes to the integrated structure of the pipe connector 1, installation only requires fixing the two connecting pipes to the two ends of the pipe connector 1, eliminating the need for complex operations such as alignment, sealing, and tightening bolts required by traditional flange joints, thereby improving installation convenience.

[0043] Therefore, the connector assembly provided in this application embodiment can reduce potential leakage points, improve the sealing of pipeline connections, reduce the risk of leakage of transmission media, and thus improve the reliability and safety of the entire connector assembly.

[0044] In some embodiments, refer to Figures 2 to 4 As shown, the first fastener is a clamp 2 or a nut, and / or the second fastener is a clamp 2 or a nut.

[0045] The first and second fasteners in this application embodiment can be configured in various combinations. Specifically, the first fastener can be a clamp 2, and the second fastener can also be a clamp 2. In this case, the first fastener fixes the first pair of connecting pipes to the first end 101 of the pipe connector 1 under pressure, and the second fastener fixes the second pair of connecting pipes to the second end 102 of the pipe connector 1 under pressure. Alternatively, the first fastener can be a clamp 2, and the second fastener can be a nut. In this case, the first fastener fixes the first pair of connecting pipes to the first end 101 of the pipe connector 1 under pressure, and the second fastener is threadedly connected to the second end 102 of the pipe connector 1, thereby pressing the second pair of connecting pipes onto the second end 102 of the pipe connector 1. Alternatively, the first fastener can be a nut, and the second fastener can be a clamp 2. In this case, the first fastener is threadedly connected to the first end 101 of the pipe connector 1, thereby pressing the first pair of connecting pipes onto the first end 101 of the pipe connector 1, and the second fastener fixes the second pair of connecting pipes to the second end 102 of the pipe connector 1 under pressure. Alternatively, the first fastener can be a nut, and the second fastener can also be a nut. In this case, the first fastener is threadedly connected to the first end 101 of the pipe connector 1, thereby pressing the first pair of pipes onto the first end 101 of the pipe connector 1. The second fastener is threadedly connected to the second end 102 of the pipe connector 1, thereby pressing the second pair of pipes onto the second end 102 of the pipe connector 1.

[0046] The first and second fasteners in this embodiment, using a combination of clamps 2 and nuts, enable rapid installation and disassembly of pipelines while ensuring good sealing. Furthermore, the combination is flexible and diverse, allowing for the selection of a suitable fastening method based on specific application requirements.

[0047] In some embodiments, refer to Figure 4 As shown, the inner wall of the clamp 2 is provided with an annular groove structure 201.

[0048] When clamp 2 is used to fasten a flexible connecting pipe (such as a negative pressure resistant transparent steel wire hose), due to the flexibility and compressibility of the hose material, it deforms under pressure and fills the annular groove structure 201 on the inner wall of clamp 2. This filling effect effectively fills any tiny gaps, thereby enhancing the sealing performance of the connection. Furthermore, the design of the annular groove structure 201 also creates one or more additional sealing surfaces, increasing the length and complexity of the path through which fluid leakage can occur, further reducing the likelihood of leakage.

[0049] Understandably, after the hose is filled into the annular groove structure 201, it not only enhances the sealing performance, but also plays a similar "locking" role, reducing the possibility of the hose sliding relative to the clamp 2 and greatly improving the stability of the connection.

[0050] Therefore, by providing an annular groove structure 201 on the inner wall of the clamp 2, this embodiment of the application not only improves the sealing performance of the pipe connection, but also enhances the stability of the connection, effectively preventing safety hazards caused by loosening.

[0051] In some embodiments, refer to Figure 4 As shown, the annular groove structure 201 includes multiple annular grooves arranged at intervals along the axial direction of the clamp 2.

[0052] This design means that each annular groove acts as an additional sealing layer. When the hose is tightened by clamp 2, it fills these grooves, forming multiple sealing points. Compared to a single annular groove design, multiple grooves provide more complex leakage paths, significantly improving sealing performance. Furthermore, multiple grooves help distribute the pressure applied to the hose more evenly. This not only prevents hose damage caused by excessive local pressure but also ensures that the entire contact surface effectively participates in sealing, improving the overall sealing effect. In addition, each groove filled with hose material can be considered a "locking point," and together they greatly increase the difficulty of the hose slipping out or loosening from clamp 2, effectively reducing the risk of loosening.

[0053] Therefore, by providing multiple annular grooves arranged axially at intervals on the inner wall of the clamp 2, the sealing and stability between the hose and the clamp 2 can be significantly improved, effectively preventing safety hazards caused by loosening.

[0054] In some embodiments, refer to Figures 2 to 6 As shown, the clamp 2 includes a first clamp body 202 and a second clamp body 203 that are spliced ​​together, and the first clamp body 202 and the second clamp body 203 can open or close.

[0055] The clamp 2 is divided into two parts: the first clamp body 202 and the second clamp body 203. During the installation process, the connecting pipe can be put on the end of the pipe joint 1 first, and then the two clamp bodies can be joined and tightened around the connecting pipe. Unlike the traditional integral clamp, it does not need to slide from one end to the designated position, which is particularly advantageous in environments with limited space.

[0056] Therefore, the present application embodiment, by adopting an openable and closable split clamp design, can significantly improve the ease of installation of the connector.

[0057] like Figures 4 to 6As shown, the first hoop 202 has a portion of the annular groove structure 201, and the second hoop 203 has the other portion of the annular groove structure 201. When the first hoop 202 and the second hoop 203 are assembled, the portion of the annular groove structure 201 on the first hoop 202 and the other portion of the annular groove structure 201 on the second hoop 203 are combined to form a complete annular groove structure. As an example, the clamp 2 is divided into two halves, namely the first hoop 202 and the second hoop 203. Correspondingly, the first hoop 202 has one half of the annular groove structure 201, and the second hoop 203 has the other half of the annular groove structure 201. This design facilitates processing.

[0058] In some embodiments, refer to Figures 2 to 6 As shown, one side of the first hoop 202 is rotatably connected to one side of the second hoop 203, and the other side of the first hoop 202 is connected to the other side of the second hoop 203 by a third fastener 204.

[0059] As an example, one side of the first hoop 202 is provided with at least one first connecting ear 205, and the first connecting ear 205 is provided with a first connecting hole 206. One side of the second hoop 203 is provided with at least one second connecting ear 207, and the second connecting ear 207 is provided with a second connecting hole 208. A rotating shaft 209 passes through the first connecting hole 206 and the second connecting hole 208, thereby realizing the rotatable connection between the first hoop 202 and the second hoop 203. Optionally, one side of the first hoop 202 can also be rotatably connected to one side of the second hoop 203 through components such as hinges. This design allows the clamp 2 to be opened and closed by rotation, so that the clamp 2 can be easily fitted onto the connecting pipe. Furthermore, the rotatable connection provides a certain degree of freedom for angle adjustment, allowing the position of the clamp 2 to be finely adjusted according to actual needs to ensure a good fit. In addition, the other side of the first hoop 202 is provided with a first docking part 210, which has at least one first fastening hole 211. The other side of the second hoop 203 is provided with a second docking part 212, which has at least one second fastening hole 213. At least one third fastener (such as a bolt, pin, etc.) can be inserted through the first fastening hole 211 and the second fastening hole 213 to dock the first docking part 210 and the second docking part 212. This allows for quick locking after the hoop 2 is closed, ensuring stability and operational efficiency.

[0060] In another example, the first hoop 202 has a first mating portion 210 on each side, and the first mating portion 210 has at least one first fastening hole 211. The second hoop 203 has a second mating portion 212 on each side, and the second mating portion 212 has at least one second fastening hole 213. A corresponding number of third fasteners 204 can be inserted through the first fastening holes 211 and the second fastening holes 213 to mate the first mating portions 210 on both sides of the first hoop 202 with the second mating portions 212 on both sides of the second hoop 203. During installation, the connecting pipe can be first fitted onto the end of the pipe connector 1, and then the two hoops can be joined together and fastened using the third fasteners 204 on both sides. During disassembly, the third fasteners 204 on both sides can be removed.

[0061] Therefore, the present application embodiment, through its split clamp design, can significantly improve the ease and stability of the installation of the connecting pipe.

[0062] In some embodiments, refer to Figures 2 to 6 As shown, the third fastener 204 is a bolt, which is used to connect the first hoop 202 to the second hoop 203 via a torque wrench.

[0063] A torque wrench is a tool used to precisely apply a predetermined torque. By pre-setting the required torque value, it ensures that bolts are tightened to the same tightness each time they are installed, avoiding overtightening or loosening due to human error. Furthermore, whether operated by different users or by the same user multiple times, using a torque wrench and tightening to the set torque guarantees consistent installation results, thereby improving the reliability and safety of the entire connector assembly.

[0064] Therefore, by using bolts and tightening them with a torque wrench, the embodiments of this application not only improve the convenience and reliability of the clamp 2 connection, but also ensure a stable tightening effect every time it is installed, significantly reducing the risk of pipe loosening.

[0065] In some embodiments, refer to Figure 3 As shown, the axial length L of the clamp 2 is 90-110 mm.

[0066] If the axial length of clamp 2 is less than 90mm, a shorter clamp 2 means a reduced effective contact area with the butt joint, resulting in uneven or insufficient clamping force distribution on the butt joint, which reduces the overall stability and sealing of the connection. If the axial length of clamp 2 is greater than 110mm, an excessively long clamp 2 reduces the flexibility of the entire joint assembly, requiring more operating space for installation and maintenance, making installation and disassembly more difficult, especially in space-constrained situations. Furthermore, a longer clamp 2 requires more material, increasing manufacturing costs.

[0067] Therefore, by setting the axial length of the clamp 2 to 90-110mm, this embodiment of the application can provide sufficient contact area, ensuring the tightness and sealing of the connection while taking into account the ease of installation and economy.

[0068] In some embodiments, refer to Figure 1 As shown, the outer wall of the first end 101 and the outer wall of the second end 102 are respectively surrounded by protruding structures 103.

[0069] The raised structure 103 of this application can be a wavy raised structure, a serrated raised structure, a spiral raised structure, a wedge-shaped raised structure with stepped distribution, etc. The raised structure 103 increases the contact area between the connecting pipe and the pipe fitting 1. Furthermore, when the clamp 2 is used to tighten a flexible connecting pipe (such as a negative pressure resistant transparent steel wire hose), due to the flexibility and compressibility of the hose material, it deforms under pressure and tightly adheres to the raised structure 103 on the outer wall of the pipe fitting 1 end, improving the sealing effect and further reducing the possibility of leakage. The raised structure 103 also acts as a "locking" mechanism, preventing the connecting pipe from sliding or loosening during use, thus enhancing the overall stability of the connection.

[0070] Therefore, by providing a protruding structure 103 on the outer wall of the end of the pipe connector 1 and combining it with an appropriate clamping method, the sealing and stability of the connection between the pipe connector and the pipe connector 1 can be significantly improved.

[0071] In some embodiments, refer to Figure 1 As shown, pipe fitting 1 is either a straight pipe fitting or a bent pipe fitting.

[0072] Straight pipe fittings are primarily used to directly connect two pipe sections together, forming a straight transmission path. Due to their simple geometry, straight pipe fittings are relatively easy to manufacture and can be mass-produced using standard molds, thereby reducing manufacturing costs. They are particularly suitable for most fluid or gas transmission systems requiring straight-line transmission, such as industrial production lines and water supply systems.

[0073] Pipe bends are used to change the direction of transmission paths. The bending angle of a pipe bend can be 45°, 90°, etc. Different bending angles can be selected to adapt to complex wiring requirements, depending on the actual needs. Understandably, in situations with limited space or where it is necessary to bypass obstacles, pipe bends can effectively optimize pipe layout and avoid unnecessary long-distance laying. They are particularly suitable for working environments with complex or varied terrain, such as underground pipe networks and internal building piping systems, and can flexibly handle various bends and turns.

[0074] In some embodiments, this application also provides a transformer, including: a transformer body and a connector assembly as described in the above embodiments. The transformer body is provided with an oil pipeline, which includes a first pair of connecting pipes and a second pair of connecting pipes. The first pair of connecting pipes and the second pair of connecting pipes are connected through the connector assembly.

[0075] The transformer body is equipped with oil pipelines for operations such as adding, filtering, and transferring insulating oil. In actual use, if traditional flange joints are used to connect the oil pipelines, there is a risk of oil leakage due to loosening of the joints, resulting in waste of oil resources. Furthermore, there is a risk of injury to bystanders at the moment of loosening, and the leaked oil will also cause environmental pollution.

[0076] Therefore, the transformer in this embodiment of the application, by employing an integrally molded pipe joint 1 and a clamp 2 structure, can effectively improve the sealing performance of the pipe connection, reduce the risk of oil leakage, and reduce environmental pollution. Furthermore, since the joint assembly does not require sealing elements, it also prevents foreign matter from entering the transformer through the pipe due to seal damage, thereby improving safety and reliability. In addition, the transformer in this embodiment of the application can be applied to substations, power plants, and other similar locations.

[0077] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
