Description

Technical Field

[0001] This utility model relates to the field of metal honeycomb sealing technology, specifically a modular splicing metal honeycomb sealing structure. Background Technology

[0002] With industrial development, higher demands are being placed on the operating efficiency of equipment such as centrifugal compressors, blowers, steam turbines, and gas turbines. Reducing media leakage is one of the keys to improving efficiency, and a modular, spliced ​​metal honeycomb sealing structure is required when sealing these devices.

[0003] Most currently used metal honeycomb sealing structures are difficult to disassemble and assemble, and it is also difficult to quickly install the sealing ring onto the sealing ring. During use, if the sealing ring is difficult to disassemble and assemble, it can lead to localized damage, requiring the replacement of the entire sealing ring. This increases maintenance and spare parts inventory costs, making the metal honeycomb sealing structure less practical. Furthermore, the difficulty in quickly installing the sealing ring makes the installation process cumbersome, requiring significant manual time and delaying the work process, thus reducing the convenience of the sealing structure. It is also difficult to prevent the sealing ring from deforming. During use, if the sealing ring cannot be prevented from deforming due to thermal expansion and contraction under heat or cold, it can become unusable, resulting in poor quality and a short service life for the sealing structure. Utility Model Content

[0004] The purpose of this invention is to provide a modular splicing metal honeycomb sealing structure to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular splicing metal honeycomb sealing structure, including a sealing ring, a splicing sealing mechanism is provided inside the sealing ring, the splicing sealing mechanism includes a slot, the slot is provided inside the sealing ring, a block is provided on one side of the sealing ring, a block is provided inside the slot, slots are provided inside both the slot and the block, an insert is provided inside the slot, and a sealing sleeve is provided outside the sealing ring.

[0006] As a preferred technical solution, the number of card slots is four sets, with two in each set, and the shape and size of the card slots match the shape and size of the card blocks.

[0007] As a preferred technical solution, the slot is rectangular in shape, and the number of slots is four.

[0008] As a preferred technical solution, the shape of the insert is rectangular, and the shape and size of the insert match the shape and size of the slot.

[0009] As a preferred technical solution, the shape and size of the sealing sleeve match the shape and size of the sealing ring, and the sealing ring is circular.

[0010] As a preferred technical solution, the sealing ring has honeycomb holes inside, and the honeycomb holes are hexagonal in shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of the splicing sealing mechanism, enables the disassembly and splicing of the sealing ring and facilitates the fitting of the sealing sleeve onto the sealing ring. During use, the sealing ring is spliced ​​by engaging the slot blocks and inserting the insert block into the slot. By fitting the sealing sleeve onto the outside of the sealing ring, the sealing sleeve performs the sealing work. This avoids the situation where the sealing ring is difficult to disassemble and splice, resulting in local damage and requiring the replacement of the entire sealing ring, which increases maintenance costs and spare parts inventory costs. This ensures the practicality of the metal honeycomb sealing structure and avoids the situation where the installation process of the sealing ring is complicated due to the difficulty in quickly installing it onto the sealing ring, which requires a lot of manual time to install the sealing ring onto the sealing ring and delays the work progress. This ensures the convenience of the structure.

[0013] 2. This utility model, through the design of honeycomb holes, can prevent the sealing ring from deforming. During use, the honeycomb holes release stress, preventing the sealing ring from deforming or cracking due to stress concentration. This avoids situations where the sealing ring is deformed due to thermal expansion and contraction when heated or cooled, making it unusable, thus ensuring the quality and service life of the sealing structure.

[0021] 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.

[0022] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a sealing ring 1, a splicing sealing mechanism 2 is provided inside the sealing ring 1, and honeycomb holes 3 are opened inside the sealing ring 1.

[0023] Specifically: When this sealing structure is needed, the sealing rings 1 must first be spliced ​​together using the splicing and sealing mechanism 2. After splicing, the sealing sleeve 205 is then fitted onto the sealing ring 1. The splicing and sealing mechanism 2 is used to quickly fix the sealing sleeve 205 to the outside of the sealing ring 1. Once the sealing sleeve 205 is fixed, the sealing ring 1 can be used normally for sealing. During the use of the sealing ring 1, it is necessary to prevent deformation of the sealing ring 1. Stress is released through the honeycomb holes 3 to prevent cracking and deformation of the sealing ring 1 due to stress concentration, thereby completing the work.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the sealing ring 1 is provided with a splicing sealing mechanism 2 inside. The splicing sealing mechanism 2 includes a slot 201. The slot 201 is opened inside the sealing ring 1. A block 202 is provided on one side of the sealing ring 1. The block 202 is provided inside the slot 201. Slots 203 are opened inside both the slot 201 and the block 202. Inserts 204 are provided inside the slots 203. A sealing sleeve 205 is provided outside the sealing ring 1. There are four sets of slots 201, with two slots in each set. The shape and size of the slots 201 match the shape and size of the blocks 202. The slots 203 are rectangular in shape, and there are four slots 203. The blocks 204 are rectangular in shape, and their shape and size match the shape and size of the slots 203. The shape and size of the sealing sleeve 205 match the shape and size of the sealing ring 1. The sealing ring 1 is circular in shape.

[0025] When this sealing structure is needed, the sealing rings 1 need to be spliced ​​together first. Then, the locking block 202 on the sealing ring 1 is inserted into the locking groove 201 in another sealing ring 1. After insertion, the slot 203 in the locking groove 201 is aligned with the slot 203 in the locking block 202. Then, the insert block 204 is inserted into the slot 203 to fix the sealing ring 1. The remaining sealing rings 1 are fixed in the same way to splice the sealing rings 1 into a ring shape, thus completing the splicing work. After splicing, the sealing sleeve 205 needs to be put on the sealing ring 1. At this time, the sealing sleeve 205 is directly put on the outside of the sealing ring 1 to achieve the function of quickly fixing the sealing sleeve 205, so that the sealing sleeve 205 can perform the sealing work, thus completing the sealing and fixing work.

[0026] like Figure 2 and Figure 4 As shown, the sealing ring 1 has honeycomb holes 3 inside, and the honeycomb holes 3 are hexagonal in shape.

[0027] Specifically, during the use of the sealing ring 1, it is necessary to prevent the sealing ring 1 from deforming. The set honeycomb holes 3 are used to release stress, so as to prevent the sealing ring 1 from cracking and deforming due to stress concentration, thereby completing the anti-deformation work.

[0028] The working principle of this utility model is as follows: When the sealing structure is needed, the sealing rings 1 need to be spliced ​​together first. Then, the locking block 202 on the sealing ring 1 is inserted into the locking groove 201 inside another sealing ring 1. After insertion, the slot 203 in the locking groove 201 is aligned with the slot 203 in the locking block 202. Then, the insert block 204 is inserted into the slot 203 to fix the sealing ring 1. The remaining sealing rings 1 are fixed in the same way, and the sealing rings 1 are spliced ​​into a circular ring, thus completing the splicing work. After splicing... At this point, the sealing sleeve 205 needs to be fitted onto the sealing ring 1. The sealing sleeve 205 is directly fitted onto the outside of the sealing ring 1 to quickly fix the sealing sleeve 205, allowing it to perform the sealing work. After the sealing sleeve 205 is fixed, the sealing ring 1 can be used normally for sealing. During the use of the sealing ring 1, it is necessary to prevent the sealing ring 1 from deforming. The honeycomb holes 3 are used to release stress and prevent the sealing ring 1 from cracking or deforming due to stress concentration, thus completing the anti-deformation work.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
