Description

Technical Field

[0001] This utility model relates to the field of connecting flange technology, and in particular to an installation structure for a connecting flange. Background Technology

[0002] A connecting flange is used to secure and connect pipes, equipment, or parts together to form a continuous system. It allows for easy disassembly and reinstallation of components, can withstand working pressure and temperature, provides reliable sealing performance, and can compensate for installation errors within a certain range, ensuring the safe and stable operation of the system.

[0003] Existing connecting flanges can only be tightened on one side of the flange at a time during installation, and cannot be tightened symmetrically on the outside of the flange at the same time. On the one hand, asymmetrical tightening will lead to uneven stress distribution between the flange and the gasket, which may cause deformation of the sealing surface and affect the sealing effect. On the other hand, uneven bolt tightness will make it difficult to disassemble later, and it will be difficult to achieve the ideal sealing effect when reinstalling.

[0004] To address the above issues, we have introduced an installation structure for connecting flanges. Utility Model Content

[0005] This utility model discloses an installation structure for a connecting flange, which aims to solve the technical problem that the outer side of the flange cannot be symmetrically fastened at the same time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation structure for a connecting flange includes a first flange and a second flange. The second flange is disposed on one side of the first flange. Five side grooves are symmetrically opened on the outer sides of the first flange and the second flange, which are close to each other. Five connecting blocks are rotatably connected to the outer side of the first flange. A threaded rod is rotatably connected to one side of each connecting block. The threaded rod passes through the corresponding side groove. A nut is threadedly connected to the end of each threaded rod away from the connecting block. A first gear is fixedly connected to the outer end of each threaded rod. A second gear is rotatably connected to the outer side of the first flange. The first gear meshes with the second gear.

[0008] By setting the first and second flanges to be tightly connected through the side groove and connecting block structure, the threaded rod passes through the side groove and the flange is tightened by the nut, thus achieving a firm connection between the two flanges. The meshing design of the first gear and the second gear makes the connection and disassembly of the flanges more convenient and faster, reducing the tedious steps of manual operation and improving installation efficiency.

[0009] In a preferred embodiment, a motor is fixedly connected to the outer side of the first flange, and a third gear is fixedly connected to the output shaft of the motor, the third gear meshing with the second gear.

[0010] By setting the motor to drive the second gear through the third gear, automatic rotation and fastening are achieved, reducing the workload of manual operation and significantly improving the efficiency of flange installation and disassembly. It is especially suitable for occasions that require frequent disassembly and assembly, improving the accuracy and consistency of the connection and ensuring the robustness of the flange.

[0011] In a preferred embodiment, the side grooves on the second flange away from the first flange are provided with slots, and the nuts are used in conjunction with the corresponding slots.

[0012] By using a slot and nut together, the nut can be accurately engaged and locked during the connection of the first and second flanges, preventing the nut from loosening and ensuring stability and safety. This is especially helpful in improving the reliability of the connection under high pressure or vibration.

[0013] In a preferred embodiment, a sealing ring is fixedly connected to the side of the first flange closest to the second flange, and a sealing groove is provided on the side of the second flange closest to the first flange, wherein the sealing ring and the sealing groove are used in conjunction.

[0014] The sealing function is provided by the combination of sealing ring and sealing groove, which ensures that the connection between the first flange and the second flange can effectively prevent the leakage of liquid or gas. This design greatly improves the performance of the flange in the liquid pipeline system and ensures the safe operation of the system.

[0015] In a preferred embodiment, the motor is electrically connected to an external control device.

[0016] By setting up remote or automated control equipment, operators can easily adjust the tightness of flange connections, improving operational convenience and efficiency, reducing human error, and making it suitable for automated production environments.

[0017] The mounting structure for the connecting flange provided by this utility model has the following advantages:

[0018] In this invention, the installation structure of the aforementioned connecting flange, when in use, involves threaded rods penetrating into the side grooves of the first and second flanges. The rotation of the second gear simultaneously engages with the first gears outside multiple threaded rods, causing the threaded rods to rotate and engage with corresponding nuts. This allows for symmetrical tightening of both the first and second flanges. On one hand, the uniform force distribution improves the safety and stability of the connection, reducing system failures or safety hazards caused by connection failures. On the other hand, symmetrical tightening ensures uniform stress distribution on both the first and second flanges, thereby reducing the risk of deformation of the sealing surface. Compared to traditional devices, this significantly improves operational quality and efficiency. Attached Figure Description

The first gear 7 is meshed with the second gear 8.

[0028] In this embodiment, the first flange 1 and the second flange 2 are tightly connected by the side groove 3 and the connecting block 4. The threaded rod 5 passes through the side groove 3 and is fastened by the nut 6 to achieve a firm connection between the two flanges. The meshing design of the first gear 7 and the second gear 8 makes the connection and disassembly of the flanges more convenient and quick, reduces the tedious steps of manual operation, and improves the installation efficiency.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, a motor 9 is fixedly connected to the outer side of the first flange 1, and a third gear 10 is fixedly connected to the output shaft of the motor 9. The third gear 10 is meshed with the second gear 8.

[0030] In this embodiment, the motor 9 drives the second gear 8 through the third gear 10 to achieve automatic rotation and fastening, reducing the workload of manual operation and significantly improving the efficiency of installing and disassembling the flange.

[0031] Reference Figure 2 and Figure 5 In a preferred embodiment, the side groove 3 on the second flange 2 is provided with a slot 11 on the side away from the first flange 1, and the nuts 6 are used in conjunction with the corresponding slot 11.

[0032] In this embodiment, the use of the slot 11 and the nut 6 together ensures that the nut 6 can be accurately engaged and locked during the connection of the first flange 1 and the second flange 2, preventing the nut 6 from loosening and ensuring stability and safety.

The distal end of the threaded rod 5 passes through the side groove 3 and engages with a nut 6 to fix the second flange 2. One end of the threaded rod 5 is fixed with a first gear 7, which meshes with a second gear 8 installed on the outside of the first flange 1. Through gear meshing, the threaded rod 5 rotates and operates synchronously. A motor 9 is fixed on the outside of the first flange 1, and a third gear 10 is connected to its output shaft. The third gear 10 meshes with the second gear 8, and the motor 9 drives the threaded rod 5. The slot 11 on the second flange 2 provides a more secure fit for the nut 6. The sealing ring 12 and sealing groove 13 provide a seal inside the first flange 1 and the second flange 2, preventing liquid or gas leakage. Through symmetrical tightening, the stress distribution of the first flange 1 and the second flange 2 is ensured to be uniform, thereby reducing the risk of deformation of the sealing surface. This significantly improves the work quality and efficiency compared to traditional devices.
