Description

Technical Field

[0001] This utility model relates to the field of pipe joint technology, and in particular to a grooved flange conversion joint. Background Technology

[0002] Flanges are an important connection method in pipeline construction because they facilitate disassembly, maintenance, and replacement of pipes, fittings, or equipment. When assembling existing flanges, a gasket must be placed between them to ensure the sealing of the flange connection. However, since the flange does not have a gasket positioning structure, the gasket is not easy to align precisely with the flange, which affects the installation of subsequent bolts and other structures. This requires constant adjustment of the alignment, making the operation very troublesome.

[0003] In the prior art, patent (CN219933260U) proposes a grooved flange conversion joint, including a flange and a connector sleeve. The connector sleeve is fixedly connected to the top of the flange. Several bolt holes are opened on the flange. A groove is opened on the outer surface of the connector sleeve. A positioning ring is fixedly connected to the edge of the bottom surface of the flange. Two first protrusions are fixedly connected to the bottom surface of the flange. The positioning ring can pre-position the gasket and align it with the flange. Afterwards, only the gasket needs to be rotated to align the bolt holes with the flange, reducing the trouble of adjustment. The first protrusion abuts against the gasket, and the first and second protrusions interlock with each other. The second protrusion of the gasket abuts against the bottom surface of the flange, effectively achieving a tight seal between the gasket and the flange. It is a four-layer seal, which greatly improves the sealing performance.

[0004] However, in the aforementioned prior art, the stability and sealing of the pipe after it is connected to the joint sleeve are poor, and it is not convenient to quickly disassemble and install it. Summary of the Invention

[0005] The purpose of this utility model is to provide a grooved flange conversion joint, which solves the problems of poor stability and sealing of pipelines after they are connected to the joint cylinder, and the inconvenience of quick disassembly and installation in the prior art.

[0006] To achieve the above objectives, this utility model provides a grooved flange adapter, including a flange and a connecting mechanism. The connecting mechanism includes a connector sleeve, a top ring, a welding ring, a stabilizing component, a supporting component, and an inner sleeve. The inner sleeve is fixedly connected to the connector sleeve and located on the inner wall of the connector sleeve. The supporting component is fixedly connected to the flange and located below the flange. The stabilizing component is fixedly connected to the connector sleeve and located on the periphery of the connector sleeve. The welding ring and the connector sleeve are both fixedly connected to the flange and located above the flange. The top ring is fixedly connected to the connector sleeve and located above the connector sleeve.

[0007] The stabilizing component includes a side ring, multiple uprights, and a stabilizing ring. The stabilizing ring is fixedly connected to the connector cylinder and located on the periphery of the connector cylinder. The lower end of each upright is fixedly connected to the stabilizing ring and located above the stabilizing ring. The upper end of each upright is fixedly connected to the side ring and located below the side ring.

[0008] The supporting assembly includes a bottom ring and a positioning ring. The positioning ring is fixedly connected to the flange and located on the periphery of the flange. The bottom ring is fixedly connected to the connector cylinder and located at the lower end of the connector cylinder.

[0009] The built-in cylinder includes a cylinder body and multiple washers. Each washer is fixedly connected to the cylinder body and located below the cylinder body. The cylinder body is fixedly connected to the connector cylinder and located on the inner side wall of the connector cylinder.

[0010] The flange includes a disc body and multiple perforated sleeves. Each perforated sleeve is fixedly connected to the disc body and located on the periphery of the disc body. The disc body is fixedly connected to the connector cylinder and located below the connector cylinder.

[0011] This utility model discloses a grooved flange conversion joint. The stabilizing ring within the stabilizing assembly maintains its own stability under the support of multiple uprights and side rings. During the process of connecting the pipeline passing through and leaving the pipeline, the movement posture of the connecting pipeline is constantly corrected, ensuring stable airtightness after connection and quick performance during disassembly. This design has a simple structure, is easy to manufacture, and solves the problems of poor stability and sealing of pipelines after connection to the joint cylinder, as well as the inconvenience of quick disassembly and installation.

[0020] This utility model provides a grooved flange conversion joint, including a flange 101 and a connecting mechanism 102. The connecting mechanism 102 includes a joint cylinder 103, a top ring 104, a welding ring 105, a stabilizing component 106, a supporting component 107, and an inner cylinder 108. The stabilizing component 106 includes a side ring 109, multiple uprights 110, and a stabilizing ring 111. The supporting component 107 includes a bottom ring 112 and a positioning ring 113. The inner cylinder 108 includes a cylinder body 114 and multiple gaskets 115. The flange 101 includes a disc body 116 and multiple perforated sleeves 117.

[0021] In this specific embodiment, the inner cylinder 108 is fixedly connected to the joint cylinder 103, the supporting assembly 107 is fixedly connected to the flange 101, the stabilizing assembly 106 is fixedly connected to the joint cylinder 103, the welding ring 105 and the joint cylinder 103 are both fixedly connected to the flange 101, the top ring 104 is fixedly connected to the joint cylinder 103, the stabilizing ring 111 is fixedly connected to the joint cylinder 103, the lower end of each upright 110 is fixedly connected to the stabilizing ring 111, the upper end of each upright 110 is fixedly connected to the side ring 109, the positioning ring 113 is fixedly connected to the flange 101, the bottom ring 112 is fixedly connected to the joint cylinder 103, and each gasket... All 115 are fixedly connected to the cylinder 114, the cylinder 114 is fixedly connected to the connector cylinder 103, each of the hole sleeves 117 is fixedly connected to the disc 116, and the disc 116 is fixedly connected to the connector cylinder 103. The stabilizing ring 111 in the stabilizing component 106 maintains its own stable posture under the support of multiple uprights 110 and the side ring 109. When the connecting pipe passes through and leaves, it constantly corrects the movement posture of the connecting pipe, ensuring stable airtightness after connection and quick performance during disassembly. This design is simple in structure, easy to produce, and solves the problem of poor stability and sealing of the pipe after it is connected to the connector cylinder 103, and the inconvenience of quick disassembly and installation.

[0022] The built-in cylinder 108 is located on the inner wall of the connector cylinder 103, the abutment component 107 is located below the flange 101, the stabilizing component 106 is located on the periphery of the connector cylinder 103, the welding ring 105 and the connector cylinder 103 are both located above the flange 101, and the top ring 104 is located above the connector cylinder 103. When connecting the pipe, the pipe connection end is first passed through the stabilizing ring 111, which limits its position. Then, the pipe is moved downward and abuts against the connector cylinder 103 and the top ring 104. After they are in contact, the connector cylinder 103 is rotated to tighten the top ring 104 and the connecting pipe again. During this process, each upright 110 supports the stabilizing ring 111, keeping the stabilizing ring 111 stable and ensuring that the pipe connection process is balanced and does not wobble. Similarly, the top ring 104 can be smoothly removed from the pipe during the pipe disassembly process, enabling quick disassembly and installation.

[0023] Secondly, the stabilizing ring 111 is located around the periphery of the connector cylinder 103, the lower end of each upright 110 is located above the stabilizing ring 111, and the upper end of each upright 110 is located below the side ring 109. The positioning ring 113 is located around the periphery of the flange 101, and the bottom ring 112 is located at the lower end of the connector cylinder 103. Multiple hole sleeves 117 on the periphery of the disc body 116 are fixed inside the corresponding holes, providing convenience for workers to install screws through the corresponding hole sleeves 117. The inner wall of each hole sleeve 117 has threads that are compatible with the screws to be installed, so workers can directly connect the disc body 116 to other pipe flanges, improving installation efficiency.

[0024] Meanwhile, each washer 115 is located below the cylinder 114, which is located on the inner wall of the connector cylinder 103. Each sleeve 117 is located on the periphery of the disc 116, which is located below the connector cylinder 103. The top ring 104 is fixed to the upper end of the connector cylinder 103, mainly to reduce and seal the tightness of the pipe installation. The bottom ring 112 is fixed to the lower end of the connector cylinder 103, mainly to ensure the tightness of the pipe connection. Both ensure increased airtightness after the pipe connection. Similarly, the multiple washers 115 at the lower end of the cylinder 114 support the cylinder 114 and reduce collisions with the connecting pipes. The positioning ring 113 on the periphery of the disc 116 is made of a softer material and protects the disc 116 during placement, preventing the disc 116 from directly colliding with the ground or placement platform.

[0025] In this embodiment, when connecting the pipe, the pipe connection end is first passed through the stabilizing ring 111, which limits its position. Then, the pipe is moved downwards and abuts against the connector cylinder 103 and the top ring 104. After they are in contact, the connector cylinder 103 is rotated to tighten the top ring 104 and the connecting pipe again. During this process, each upright 110 supports the stabilizing ring 111, maintaining the stability of the stabilizing ring 111's posture and ensuring that the pipe connection process is balanced and does not wobble. Similarly, during pipe disassembly, the top ring 104 can be smoothly detached from the pipe, enabling quick disassembly and installation. The multiple hole sleeves 117 on the periphery of the disc body 116 are fixed inside the corresponding holes, providing convenience for workers to install screws by passing them through the corresponding hole sleeves 117. Each hole... The inner walls of sleeve 117 are threaded to match the screws to be installed, so workers can directly connect the disc 116 to other pipe flanges, improving installation efficiency. The top ring 104 is fixed to the upper end of the connector cylinder 103, mainly to reduce and seal the tightness of the pipe installation. The bottom ring 112 is fixed to the lower end of the connector cylinder 103, mainly to ensure the tightness of the pipe connection. Both ensure increased airtightness after pipe connection. Similarly, the multiple washers 115 at the lower end of the cylinder 114 support the cylinder 114 and reduce collisions with the connected pipes. The positioning rings 113 on the periphery of the disc 116 are made of soft material, which protects the disc 116 during placement and prevents it from directly colliding with the ground or placement platform.
