Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a flange with a built-in installation structure. Background Technology

[0002] A flange is a disc-shaped part used to connect pipes, valves, pumps and other equipment. They are usually used in pairs and are connected by bolts with a gasket in between to ensure a tight seal. Flanges are widely used in industries such as petroleum, chemical, power and shipbuilding. They are widely used in practice. When connecting larger pipes, flanges with built-in installation structures are needed to simplify the installation process and improve efficiency.

[0003] According to a flange with a built-in installation structure, which has application number CN202322978885.X, this solution solves the problem that flange installation usually requires manual bolt connection one by one, which leads to a slow installation and replacement process, which is not conducive to efficiency improvement and rapid installation and replacement of flanges.

[0004] However, the following problems still exist in actual use: (1) When in use, although the spring can provide a certain clamping force, in the long-term use, the clamping force will decrease due to fatigue or elastic decay of the spring, which will affect the stability of the connection and cause the connection to loosen. This will increase the safety hazards in practice and reduce the safety in actual use.

[0005] (2) After the connection is installed, the sealing is insufficient, so the medium in the pipeline (such as liquid, gas or corrosive substances) leaks from the connection, resulting in problems such as waste of resources, environmental pollution and equipment corrosion, which will increase the frequency and cost of maintenance. At the same time, the equipment may need to be replaced due to damage, further increasing the operating cost.

[0006] Therefore, this utility model introduces a flange with a built-in installation structure. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a flange with a built-in installation structure, which has the advantages of being more stable during connection and installation, and ensuring sealing after connection, thus solving the problems mentioned in the background art.

[0008] This utility model provides the following technical solution: a flange with a built-in installation structure, including a first flange and a second flange. The bottom of the first flange is provided with a connecting installation mechanism, which includes a pressure plate, a movable rod, a screw, and a limiting bolt. The outer surface of the movable rod is movably connected to the inner wall of the first flange. One end of the screw is fixedly installed to the bottom of the movable rod. The bottom of the pressure plate is fixedly connected to the other end of the movable rod. The inside of the limiting bolt is threadedly connected to the outer surface of the screw.

[0009] Preferably, a sealing mechanism is provided on the right side of the first flange. The sealing mechanism includes a first inner liner, an extension ring, and a second inner liner. The outer surface of the first inner liner is fixedly installed with the interior of the first flange. The top of the extension ring is fixedly installed with the bottom of the first inner liner. The outer surface of the second inner liner is fixedly installed with the interior of the second flange. A connecting groove is provided inside the second inner liner.

[0010] Preferably, the pressure plate has a through groove inside, the inner ring of the through groove is adapted to the outer side of the first inner liner ring, and the outer surface of the movable rod is adapted to the inner wall of the connecting groove.

[0011] Preferably, the second flange has a connecting groove inside.

[0012] Preferably, the outer side of the extension ring is adapted to the inner wall of the connecting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of flange with its own installation structure, through the use of pressure plates, screws, limit bolts, and connecting grooves, can connect the first and second flanges, achieving a more stable connection and avoiding problems such as loosening. The use of the through groove allows the inside of the groove to abut against the outer surface of the first inner liner ring during connection, further ensuring the stability of the connection. This solves the problem of connection instability caused by tension springs, achieving a more stable connection and installation, preventing loosening, reducing safety hazards in practice, and improving safety in real-world use.

[0014] 2. This type of flange with its own installation structure, through the use of a first inner liner and a second inner liner, can limit the position of the pipeline during connection and installation, ensuring accuracy during connection and installation. Through the use of the extension ring and the second inner liner, the sealing performance after the connection of the first flange and the second flange is guaranteed, thus solving the problem of how to ensure the sealing performance after connection. This can achieve a better sealing effect after connection, avoid leakage caused by poor sealing performance, and also reduce the frequency and cost of maintenance in actual practice.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 3 A flange with a built-in installation structure includes a first flange 1 and a second flange 2. The bottom of the first flange 1 is provided with a connecting installation mechanism 13. The connecting installation mechanism 13 includes a pressure plate 3, a movable rod 5, a screw 6 and a limiting bolt 7. The outer surface of the movable rod 5 is movably connected to the inner wall of the first flange 1. One end of the screw 6 is fixedly installed to the bottom of the movable rod 5. The bottom of the pressure plate 3 is fixedly connected to the other end of the movable rod 5. The inside of the limiting bolt 7 is threadedly connected to the outer surface of the screw 6. The inside of the pressure plate 3 is provided with a through groove 4. The inner ring of the through groove 4 is adapted to the outer side of the first inner liner ring 9. The outer surface of the movable rod 5 is adapted to the inner wall of the connecting groove 8.

[0019] Specifically, the movable rod 5 can move flexibly within the inner wall of the first flange 1. Combined with the threaded connection of the screw rod 6 and the limit bolt 7, the entire installation process is simple and can be completed without complicated tools or steps, greatly improving installation efficiency. The fit between the through groove 4 and the first inner liner ring 9 further enhances the stability of the connection. Simultaneously, the fit of the movable rod 5 within the connecting groove 8 makes the entire connection structure tighter and less prone to loosening, thus ensuring the long-term stability and safety of the flange connection.

[0020] Please see Figure 2 and Figure 4 A sealing mechanism 14 is provided on the right side of the first flange 1. The sealing mechanism 14 includes a first inner liner 9, an extension ring 10, and a second inner liner 11. The outer surface of the first inner liner 9 is fixedly installed with the interior of the first flange 1. The top of the extension ring 10 is fixedly installed with the bottom of the first inner liner 9. The outer surface of the second inner liner 11 is fixedly installed with the interior of the second flange 2. A connecting groove 12 is provided inside the second inner liner 11. A connecting groove 8 is provided inside the second flange 2. The outer side of the extension ring 10 is adapted to the inner wall of the connecting groove 12.

[0021] Specifically, the first inner liner ring 9 is fixedly installed inside the first flange 1, ensuring that the starting point of the seal is stable and reliable. The extension ring 10 serves as a connecting bridge, with its top fixedly installed to the bottom of the first inner liner ring 9, and its bottom outer surface adapted to the second inner liner ring 11 through the connecting groove 12, forming a continuous sealing surface that effectively prevents media leakage.

[0022] Working principle: When connecting larger pipes, the first flange 1 and the second flange 2 are first connected to the outer surfaces of the two pipe sections respectively. Then, the first flange 1 and the second flange 2 are connected. First, the limiting bolt 7 is removed from the outer surface of the screw 6. Then, the pressure plate 3 is pressed, so that the inner wall of the through groove 4 inside the pressure plate 3 is connected to the outer surface of the first inner liner ring 9, ensuring the stability of the pressure plate 3 when pressed. Next, the movable rod 5 installed at the bottom of the pressure plate 3 is pressed inside the first flange 1. The diameter of the screw 6 is smaller than the inner diameter of the connecting groove 8. Then, the position where the screw 6 is installed at the bottom of the movable rod 5 is passed through the inner wall of the connecting groove 8 inside the second flange 2, and the outer surface of the movable rod 5 slides tightly against the inner wall of the connecting groove 8. After the outer surface of the movable rod 5 is connected to the inside of the connecting groove 8, the inside of the limiting bolt 7 is threaded to the outer surface of the screw 6, and the upper surface of the limiting bolt 7 is abutted against the lower surface of the second flange 2, which can stabilize the connection between the first flange 1 and the second flange 2.

[0023] When ensuring the sealing performance after connection, when connecting the first flange 1 and the second flange 2, pressing the pressure plate 3 allows the extension ring 10 installed at the bottom of the first inner liner 9 fixedly installed inside the first flange 1 to move synchronously and connect with the inner wall of the connecting groove 12 opened inside the second inner liner 11 fixedly installed inside the second flange 2. This ensures the sealing performance during the connection and installation between the first flange 1 and the second flange 2.
