Description

Technical Field

[0001] This utility model relates to the field of compensator technology, and in particular to a sealed and durable compensator. Background Technology

[0002] Existing compensators typically use bellows fitting during production, resulting in relatively poor load-bearing capacity and wear resistance at the connection points, relatively low sealing load-bearing capacity at the compensating moving parts, and relatively low tensile strength. For some applications with high strength requirements, existing compensators cannot meet the needs. Furthermore, due to the difficulty of maintenance, existing compensators have relatively short maintenance cycles, leading to relatively high operating costs. Utility Model Content

[0003] The purpose of this utility model is to provide a sealed and durable compensator. It achieves a dual compensation function by setting two L-shaped mating frames on the outside of the main structure of the compensator, and then combining them with a bellows on the outside. The sleeve body is connected by a retaining ring inside. Through the multi-phase sealing structure of the mating position, not only is the sealing performance guaranteed during use, but the overall wear resistance is also better and the service life is longer. This can effectively reduce the maintenance and use costs in the later use and meet the use requirements of application environments with high tensile strength and sealing performance requirements.

[0004] The technical solution of this utility model is as follows:

[0005] A durable, sealed compensator, characterized in that: it comprises a cylindrical compensator sleeve body with its central axis pointing left to right; symmetrical second compensator assembly sleeves are connected to the left and right sides of the compensator sleeve body; the outer sides of the connection points between the compensator sleeve body and the second assembly sleeves are joined together by cylindrical compensator connecting retaining rings; the compensator sleeve body and the second assembly sleeves are provided with opposing L-shaped reinforcing support frames; a bellows structure is connected to the outer side of the reinforcing support frame; the two ends of the bellows structure are welded to the outer cylindrical surface of the reinforcing support frame; and circumferentially distributed compensator connecting support brackets are provided on the outer side of the reinforcing support frame. The connecting brackets are connected together by main body connecting bolts. A cylindrical combined sealing and limiting collar is provided at the position where the inside of the compensator connecting retaining ring mates with the outer cylindrical surface of the second combined sleeve. A sleeve combined limiting post is provided on the outer cylindrical surface of the second combined sleeve. A sleeve combined buffer sealing ring is provided between the sleeve combined limiting post and the combined sealing and limiting collar. A second reinforcing sealing and mating retaining ring is provided between the inside of the compensator connecting retaining ring and the outer cylindrical surface of the compensator sleeve body. The outer end face of the second reinforcing sealing and mating retaining ring is connected to the reinforcing support assembly frame on the compensator sleeve body by welding to the outer end face of the compensator connecting retaining ring.

[0006] Furthermore, the cross-section of the sleeve assembly limiting post is circular, and the end face of the sleeve assembly limiting post and the second combined sleeve are on the same plane.

[0007] Furthermore, both the combined sealing limiting collar and the sleeve combined buffer sealing ring have square cross-sections.

[0008] Furthermore, the length of the second reinforced sealing retaining ring is greater than the sum of the lengths of the combined sealing limiting collar, the sleeve combined limiting post, and the sleeve combined buffer sealing ring.

[0009] Furthermore, the dimension of the compensator connecting the outer corner is smaller than the dimension of the position closer to the second combined sleeve.

[0010] The beneficial effects of this utility model are:

[0011] This invention achieves a dual compensation effect by setting two L-shaped mating frames on the outside of the main structure of the compensator, and then combining them with a corrugated pipe on the outside. The main body of the sleeve is connected by a retaining ring inside. Through the mating position multi-phase sealing structure, not only is the sealing performance guaranteed during use, but the overall wear resistance is also better and the service life is longer. This can effectively reduce the maintenance and use costs in the later use and meet the use requirements of application environments with high tensile strength and sealing performance requirements.

Detailed Implementation

[0020] like Figures 1 to 7As shown, a sealed and durable compensator includes a cylindrical compensator sleeve body 1 with its central axis pointing left to right. Symmetrical second compensator combination sleeves 2 are connected to the left and right sides of the compensator sleeve body 1. These three components form the main body of the compensator sleeve and work together in use. The outer sides of the connection points between the compensator sleeve body 1 and the second combination sleeves 2 are joined by cylindrical compensator connecting retaining rings 3. The compensator sleeve body 1 and the second combination sleeves 2 are provided with L-shaped reinforcing support frames 5 facing opposite directions, improving the structural strength of the external positions and providing more space on the internal positions. A bellows structure 4 is connected to the outer side of the reinforcing support frame 5. The two ends of the bellows structure 4 are welded to the outer cylindrical surface of the reinforcing support frame 5, achieving external compensation. The outer side of the reinforced support frame 5 is provided with circumferentially distributed compensator connecting brackets, which are connected together by main body connecting bolts 10. A cylindrical combined sealing limiting collar 6 is provided inside the compensator connecting retaining ring 3 at the position where it mates with the outer cylindrical surface of the second combined sleeve 2, serving as the internal second compensation structure. A sleeve combined limiting post 8 is provided on the outer cylindrical surface of the second combined sleeve 2. A sleeve combined buffer sealing ring 7 is provided between the sleeve combined limiting post 8 and the combined sealing limiting collar 6. A second reinforced sealing mating retaining ring 9 is provided between the inner side of the compensator connecting retaining ring 3 and the outer cylindrical surface of the compensator sleeve body 1. The outer end face of the second reinforced sealing mating retaining ring 9 is welded to the outer end face of the compensator connecting retaining ring 3 and the reinforced support frame 5 on the compensator sleeve body 1, ensuring sealing and load-bearing capacity at both ends. This provides stronger resistance to compensation impact during use, better durability, and the overall compensation structure achieves multi-position, multi-layer sealing mating, ensuring sealing safety during use. It achieves a dual compensation function by setting two L-shaped mating frames on the outside of the main structure of the compensator, and then combining them with corrugated pipes on the outside. The main body of the sleeve is connected by retaining rings inside. Through the mating position multi-phase sealing structure, it not only ensures the sealing performance during use, but also has better overall wear resistance and longer service life. This can effectively reduce the maintenance and use costs in the later use and meet the use requirements of application environments with high tensile strength and sealing performance requirements.

[0021] Preferably, the sleeve combination limiting post 8 has a circular cross-section, and the end face of the sleeve combination limiting post 8 and the second combination sleeve 2 are on the same plane, which makes the external flatness better when they are in contact and the safety during production and processing is also higher.

[0022] Preferably, both the combined sealing limiting collar 6 and the sleeve combined buffer sealing ring 7 have square cross-sections, resulting in a larger combined contact surface when they are fitted together, which further improves the sealing stability.

[0023] Preferably, the length of the second reinforced sealing retaining ring 9 is greater than the sum of the lengths of the combined sealing limiting collar 6, the sleeve combined limiting post 8, and the sleeve combined buffer sealing ring 7, so that the load-bearing capacity of the two sides of the structure is different, the load-bearing strength of the inner side is higher, and the safety during use is more guaranteed.

[0024] Preferably, the size of the compensator connecting the outer corner is smaller than the size of the side closer to the second combined sleeve 2, making the overall product easier to assemble, taking up less space, and more convenient to use.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
