Description

Technical Field

[0001] This utility model belongs to the field of marine pipeline end face flanges, and specifically relates to a marine pipeline end face flange. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, attached to the pipe ends. Flanges have holes, and bolts are used to tighten two flanges together. A gasket is used for sealing between the flanges. A flange is a disc-shaped component, most commonly found in piping engineering, and flanges are always used in pairs. In piping engineering, flanges are mainly used for connecting pipes. At the ends where two pipes need to be connected, a flange plate is installed on each side. Threaded flanges can be used for low-pressure pipelines, while welded flanges are used for pressures above 4 kg. A gasket is placed between the two flange plates, and then they are tightened with bolts.

[0003] Existing technologies have specifically developed some marine pipe end face flanges. For example, Chinese patent with announcement number "CN112483742A" discloses "a marine pipe end face flange" which improves the sealing performance of the pipe end face by designing two layers of bosses, and also improves the versatility of the structure. By setting a reinforcing rib between the first boss and the second boss, the strength of the pipe end face flange is further improved and its service life is extended.

[0004] Although the design of two layers of bosses improves the sealing performance of the pipe end face and enhances the versatility of the structure, and the addition of a reinforcing rib between the first and second bosses further improves the strength of the pipe end face flange and extends its service life, the sealing performance of the above structure is poor during use. This results in low flange sealing performance and makes disassembly and maintenance difficult for workers. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a marine pipeline end face flange to solve the problems of marine pipeline end face flanges.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A marine pipe end flange includes a mounting ring, one end of which is integrally formed with a circular plate, and the end of the mounting ring adjacent to the circular plate is integrally formed with a connecting seat. The end of the connecting seat away from the mounting ring is threadedly connected to a connecting ring, and the outer ring of the connecting seat away from the mounting ring is integrally formed with a third mounting plate. The end of the third mounting plate away from the mounting ring is fixedly connected to a second mounting plate, and the end of the second mounting plate away from the third mounting plate is integrally formed with an externally protruding threaded plate. The outer ring of the externally protruding threaded plate is threadedly connected to a pressure plate, and the end of the pressure plate away from the externally protruding threaded plate is integrally formed with a connecting plate.

[0008] As a preferred technical solution, the mounting ring has multiple assembly openings inside, and a circular plate is integrally formed at one end of the mounting ring near the connecting seat. The connecting plate, the connecting ring, the connecting seat, and the base plate all have circular openings inside.

[0009] As a preferred technical solution, multiple third reinforcing rods are fixedly installed at the end of the circular plate away from the mounting ring, and the ends of the multiple third reinforcing rods away from the circular plate are fixedly installed at one end of the third mounting plate.

[0010] As a preferred technical solution, the end of the connecting seat away from the mounting ring is provided with an external thread, the end of the connecting seat away from the mounting ring is provided with a second sealing groove, and the outer ring of the connecting seat is provided with a third sealing groove at a position close to the third mounting plate.

[0011] As a preferred technical solution, a second internal thread is provided inside one end of the connecting ring near the connecting seat, and a third sealing ring is integrally formed at one end of the connecting ring near the connecting seat. A second sealing ring is integrally formed inside the connecting ring above the second internal thread. The second internal thread is threadedly connected to the outer ring of the external thread. The third sealing ring is slidably installed inside the third sealing groove, and the second sealing ring is slidably installed inside the second sealing groove.

[0012] As a preferred technical solution, multiple second reinforcing rods are fixedly installed on the end of the third mounting plate away from the third reinforcing rod. The outer ring of the connecting plate is integrally formed with a first mounting plate. Multiple first reinforcing rods are fixedly installed on the outer side of the end of the pressing plate close to the first mounting plate. The ends of the multiple first reinforcing rods away from the pressing plate are fixedly installed on the end of the first mounting plate away from the connecting plate.

[0013] As a preferred technical solution, the end of the pressing plate near the second mounting plate has a first internal thread, and a first sealing ring is integrally formed inside the pressing plate above the first internal thread. The upper end of the first sealing ring has a pressing groove. The pressing plate is threadedly connected to the outer protruding threaded plate through the first internal thread. The first sealing ring seals the outer ring of the connecting ring, and the pressing groove is pressed and installed at the end of the connecting ring away from the connecting seat.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the third sealing ring, which is integrally formed at one end of the connecting ring, will slide and install inside the third sealing groove. Then, the second sealing ring provided inside the connecting ring will slide and install inside the second sealing groove. This can effectively fix the connecting ring and the connecting seat, and also effectively improve the sealing effect.

[0016] Secondly, when the worker connects the pressing plate to one end of the second mounting plate by thread, the pressing plate can better press the connecting ring. After the thread connection, the first sealing ring inside the pressing plate will slide and install on the outer ring of the connecting ring to achieve a seal. Then, the pressing groove will also effectively fit against one end of the connecting ring to provide a better sealing effect for the pressing plate. This effectively provides workers with a convenient way to disassemble and install, and can also effectively improve the sealing performance. Attached Figure Description
