Description

Technical Field

[0001] This utility model relates to the field of flange assembly technology, specifically a multi-layer sealing flange assembly device. Background Technology

[0002] Multi-layer sealing flange assembly refers to the process of assembling the flange body, sealing elements, and connecting bolts and nuts in a specific sequence by setting two or more layers of sealing elements (such as gaskets and sealing rings) in the flange connection structure. The purpose is to enhance the sealing performance of the flange connection through the synergistic effect of the multi-layer sealing structure, improve its adaptability to complex operating conditions such as high pressure, high temperature, and corrosive media, and ensure the safety and reliability of the system operation. During assembly, it is necessary to ensure that the installation position of each layer of sealing elements is accurate and the force is evenly distributed, and that the bolts are tightened to the specified torque and sequence to optimize the multi-layer sealing effect.

[0003] However, in the current process of assembling multi-layer sealing flanges with bolts and nuts, the bolts may be too long, which may require the nuts to be tightened a lot of turns. This requires workers to continuously tighten the nuts. Since flange assembly requires a large number of bolts and nuts, this greatly affects the assembly efficiency. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model discloses a multi-layer sealing flange assembly device, including an installation ring 1 and an assembly assembly. The installation ring 1 is the main structure of the device and is used to install other structures. A rotating component 11 is rotatably arranged on the inner side of the installation ring 1. A ball bearing 14 is rolled on the connection side between the installation ring 1 and the rotating component 11. That is, the installation ring 1 and the rotating component 11 do not directly contact each other. The rotating component 11 is supported by the ball bearing 14 and the ball bearing 14 rolls to reduce the friction when the rotating component 11 rotates. The assembly assembly is the assembly structure of the multi-layer sealing flange.

[0026] The assembly includes an internal hexagonal tube 12, an internally threaded hexagonal block 13 on the outside of the internal hexagonal tube 12, a hexagonal groove 22 on the inside of the rotating part 11, the internally threaded hexagonal block 13 being installed and removed in the hexagonal groove 22, a threaded post 23 being rotatably provided inside the hexagonal groove 22, the threaded post 23 being threadedly connected to the internally threaded hexagonal block 13, a rotating bolt 24 being provided on the outside of the threaded post 23, the rotating bolt 24 being used to rotate the threaded post 23 from the outside, that is, by installing the internally threaded hexagonal block 13 in the hexagonal groove 22, and rotating the threaded post 23 by rotating the rotating bolt 24, the threaded post 23 is connected to the internally threaded hexagonal block 13, at which point the internal hexagonal tube 12 can be fixed on the rotating part 11;

[0027] The rotating bolt 24 has a sliding insert 33 inside, and a spring 34 is provided on the top inner side of the rotating bolt 24. The bottom of the spring 34 is connected to the sliding insert 33, and the spring 34 always pushes the sliding insert 33. The bottom outer side of the rotating part 11 has a socket 4, and the sliding insert 33 is installed and removed in the socket 4. When the threaded post 23 is connected to the internal threaded hexagonal block 13, the bottom of the sliding insert 33 is aligned with the socket 4. The spring 34 pushes the sliding insert 33, so that the sliding insert 33 is inserted into the socket 4, fixing the rotating bolt 24 and preventing it from rotating. The outer side of the sliding insert 33 has a pulling structure, so that the sliding insert 33 can be pulled upward from the outside.

[0028] The assembly components also include bolts 2 and nuts 21. Nuts 21 and bolts 2 are threaded together, that is, the flange is assembled by nuts 21 and bolts 2. The outer side of nuts 21 is slidably connected to the inner side of hexagonal tubes 12. After nuts 21 are installed on bolts 2, hexagonal tubes 12 are fitted onto the outer side of nuts 21, and bolts 2 are manually limited. A motor 3 is installed on one side of the mounting ring 1. A first bevel gear 31 is installed on the drive shaft of the motor 3. A second bevel gear 32 is installed on the outer side of the rotating part 11. The first bevel gear 31 and the second bevel gear 32 mesh. The switch of the motor 3 is installed on the motor 3. A handle 41 is installed on one side of the motor 3. The operator holds the handle 41 to use the equipment. The motor 3 drives the first bevel gear 31 to rotate. Through gear transmission, the rotating part 11 drives the hexagonal tubes 12 and nuts 21 to rotate in sequence, so that nuts 21 can be quickly tightened onto bolts 2, thereby speeding up the assembly efficiency.

[0029] The internal hexagonal tube 12 is available in various sizes (internal hexagonal size) and lengths, but the internally threaded hexagonal block 13 behind it remains unchanged. This allows it to be used with different internal hexagonal tubes 12 to accommodate different bolts 2 and nuts 21.

[0030] The working principle of this utility model is as follows: By installing the internally threaded hexagonal block 13 in the hexagonal slot 22, and rotating the threaded post 23 by rotating the rotating bolt 24, the threaded post 23 is connected to the internally threaded hexagonal block 13. At this time, the internal hexagonal tube 12 can be fixed on the rotating part 11. When the threaded post 23 is connected to the internally threaded hexagonal block 13, the bottom of the sliding insert 33 is aligned with the socket 4. The sliding insert 33 is pushed by the spring 34, so that the sliding insert 33 is inserted into the socket 4, fixing the rotating bolt 24 and preventing it from rotating. The flange is assembled by the nut 21 and the bolt 2. After the nut 21 is installed on the bolt 2, the internal hexagonal tube 12 is put on the outside of the nut 21, and the bolt 2 is manually limited. The motor 3 drives the first bevel gear 31 to rotate. Through gear transmission, the rotating part 11 drives the internal hexagonal tube 12 and the nut 21 to rotate in sequence, so that the nut 21 can be quickly tightened on the bolt 2, thereby speeding up the assembly efficiency. By replacing different internal hexagonal tubes 12, different bolts 2 and nuts 21 can be adapted.
