Description

Technical Field

[0001] The invention relates to the technical field of flange rings, and more specifically to a high-pressure butt-welding flange. Background Art

[0002] Flange ring, also known as flange ring or gasket, is a mechanical component used to achieve sealing function. It is widely used in the connection of industrial pipelines, containers, equipment, and the installation of specific household products such as toilets. Its main function is to prevent fluid or gas leakage and ensure the sealing and stability of the system.

[0003] Flange rings are usually welded at both ends of the pipeline to achieve the connection between the two sections of the pipeline. During the specific use process, the welding position will cause welds to form over time and due to external environmental factors and the force at the connection position of the two sections of the pipeline. When a weld is formed between the welded flange ring and the pipeline, the welding relationship between the flange ring and the pipeline is no longer firm, and there is a risk of collapse.

[0004] Therefore, it is necessary to provide a high-pressure butt welding flange to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a high-pressure butt-welding flange.

[0007] Furthermore, a rotating bead located inside the connecting barrel is provided at one end of the connecting column away from the locking structure.

[0008] Furthermore, the locking structure includes a first locking arm, one end of the first locking arm is hinged to the second locking arm, one end of the second locking arm is hinged to the third locking arm, the other end of the first locking arm is fixedly connected to a rotating block, the other end of the third locking arm is fixedly connected to a locking block, and the top of the rotating block is rotatably connected to the locking block.

[0009] Furthermore, one end of the first connecting rod away from the connecting rod bolt is fixedly connected to the outer wall of the flange body, and a side of the connecting rod bolt away from the first connecting rod is provided with a thread, which is adapted to the threaded barrel.

[0011] Furthermore, the locking arm includes a locking threaded rod and a locking ring, and a locking groove is formed on the top of the locking block, and the size of the locking groove is adapted to the size of the locking threaded rod.

[0012] The beneficial effects of this utility model are:

[0013] The utility model is provided with a connecting structure and a locking structure, which can help the device to fix the two flange bodies on the two ends of the pipeline during operation.

[0025] like Figure 1-4 As shown, the present application provides a high-pressure butt-welding flange, including a flange body 1, a connecting structure 2, a locking structure 3 and a locking arm 306, the connecting structure 2 includes a first connecting rod 201, one end of the first connecting rod 201 is connected to a connecting rod bolt 202, one end of the connecting rod bolt 202 is connected to a threaded barrel 203, one end of the threaded barrel 203 is fixedly connected to a hexagonal bolt 204, one end of the hexagonal bolt 204 is connected to a connecting column 207, the outer wall of the connecting column 207 is provided with a connecting barrel 205, and the other end of the connecting barrel 205 is connected to the locking structure 3.

[0026] One end of the connecting column 207 away from the locking structure 3 is provided with a rotating bead 208 located inside the connecting barrel 205 .

[0027] The locking structure 3 includes a first locking arm 301, one end of the first locking arm 301 is hinged to the second locking arm 302, one end of the second locking arm 302 is hinged to the third locking arm 303, the other end of the first locking arm 301 is fixedly connected to a rotating block 304, the other end of the third locking arm 303 is fixedly connected to a locking block 305, and the top of the rotating block 304 is rotatably connected to the locking block 305.

[0028] One end of the first connecting rod 201 away from the connecting rod bolt 202 is fixedly connected to the outer wall of the flange body 1 , and a thread is formed on one side of the connecting rod bolt 202 away from the first connecting rod 201 , and the thread is matched with the thread barrel 203 .

[0029] The connecting column 207 is rotatably connected in the connecting barrel 205 .

[0030] The locking arm 306 includes a locking threaded rod and a locking ring. A locking groove is formed on the top of the locking block 305, and the size of the locking groove matches the size of the locking threaded rod.

[0031] The hinged positions of the first locking arm 301, the second locking arm 302, and the third locking arm 303 are connected by a detachable rivet structure.

[0032] Three connection structures 2 are installed on one side of the flange body 1 , and the second connecting rods 206 of the three connection structures 2 are connected to the first locking arm 301 , the second locking arm 302 , and the third locking arm 303 respectively by rivets.

[0033] Working principle:

[0034] Before using the device, first check the various components of the device to ensure that the various components of the device cooperate properly and ensure that the device can work normally.

[0035] When the device needs to be used, first disassemble its threaded barrel 203 and connecting rod bolt 202 to divide its connecting structure 2 into two sections. The user first assembles its locking structure 3 around the pipe. After assembly, ensure that the first locking arm 301, the second locking arm 302 and the third locking arm 303 can hold the pipe, and lock the locking structure 3 with the pipe through the cooperation between the rotating block 304, the locking block 305 and the locking arm 306.

[0036] When the locking is completed, the user matches the flange body 1 with one end of the pipe, so that the flange body 1 drives the first connecting rod 201 and the connecting rod bolt 202 to move. After the connecting rod bolt 202 and the threaded barrel 203 are matched, the threaded barrel 203 is rotated to lock the connecting rod bolt 202 and the threaded barrel 203. The rotation of the threaded barrel 203 drives the connecting column 207 to rotate in the connecting barrel 205. When the threaded barrel 203 is rotated to the extreme position, the flange body 1 is fully matched with the pipe, and the user welds the flange body 1 to the pipe.

[0037] By providing a connecting structure 2 and a locking structure 3, the device can help fix the two flange bodies 1 at the two ends of the pipeline during operation. By adopting the connection relationship between the connecting structure 2 and the locking structure 3, the force generated at the connection position of the two flange bodies 1 is distributed to the pipeline, avoiding the problem of welds at the welding points due to excessive force, thereby ensuring the stability of flange welding.
