Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a bypass thrustless sleeve compensator with a double-layer sealing structure, such as... Figure 1 and Figure 2 As shown, it includes a housing assembly 1, which includes an outer tube 11. An inner tube 12 is slidably connected to the right side of the outer tube 11. A corrugated tube 13 is provided between the inner tube 12 and the outer tube 11. A connecting plate 14 is fixed on the outer tube 11.

[0021] Among them, an annular fixing plate is fixed on the inner tube 12. At least six sets of threaded holes 333 are opened on the annular fixing plate. The six sets of threaded holes 333 are equally distributed on the annular fixing plate. The threaded holes 333 on the annular fixing plate, the connecting plate 14 and the sealing plate 25 all have screws passing through them, thereby playing an auxiliary limiting role.

[0022] In the above scheme, the corrugated pipe 13 between the outer tube 11 and the inner tube 12 plays a compensating role, and a rubber sealing ring is provided between the connecting plate 14 and the sealing plate 25 to ensure the sealing effect.

[0023] like Figure 1 and Figure 3 As shown, a double-layer sealing structure 2 is embedded in the outer shell assembly 1. The double-layer sealing structure 2 includes a first filling layer 21, a first sealing component 22 is provided on the right side of the first filling layer 21, a second sealing component 23 is provided on the right side of the first sealing component 22, a second filling layer 24 is provided on the right side of the second sealing component 23, and a sealing plate 25 is provided on the right side of the second filling layer 24. The first sealing component 22 includes a first rubber sealing ring 221, and a rubber pressure plate 222 is provided on the right side of the first rubber sealing ring 221.

[0024] The first sealing component 22 and the second sealing component 23 have the same structure. The second sealing component 23 and the second filling layer 24 are both made of flexible graphite rings, which have the characteristics of high strength, low friction coefficient and non-aging. They can maintain good sealing performance and long service life in harsh environments and ensure sealing effect.

[0025] In the above scheme, the sealing plate 25 is attached to the connecting plate 14, and the bolt 334 passes through the sealing plate 25 and the connecting plate 14 to limit and fix them. The first filling layer 21 and the second filling layer 24 assist in sealing, compensating and protecting the bypass thrustless sleeve compensator. The rubber pressure plate 222 limits the first rubber sealing ring 221. The setting of the first rubber sealing ring 221 plays a sealing role. At the same time, with the assistance of the second sealing component 23, it seals again, thereby ensuring the sealing effect.

The support structure 3 includes a first L-shaped plate 31, and a second L-shaped plate 32 is slidably connected to the first L-shaped plate 31. A height adjustment assembly 33 is fixed on the lower side of both the first L-shaped plate 31 and the second L-shaped plate 32. The height adjustment assembly 33 includes a support rod 331, and a sliding rod 332 is slidably connected to the support rod 331. A threaded hole 333 is opened on the sliding rod 332. The support rod 331 and the sliding rod 332 are disassembled and installed by bolts 334. A shock absorber 335 is fixed on the lower side of the support rod 331, and a base 336 is fixed on the lower side of the shock absorber 335.

[0027] The first L-shaped plate 31 has a groove, and the second L-shaped plate 32 is slidably connected to the groove in the first L-shaped plate 31.

[0028] Specifically, there are two sets of height adjustment components 33, and the two sets of height adjustment components 33 are symmetrically arranged about the central axis of the first L-shaped plate 31;

[0029] Furthermore, a sliding groove is provided in the support rod 331, and a sliding rod 332 is slidably connected in the sliding groove. Multiple sets of threaded holes 333 are provided on the sliding rod 332, and the multiple sets of threaded holes 333 are evenly distributed on the sliding rod 332.

[0030] In the above scheme, the second L-shaped plate 32 is stretched from the first L-shaped plate 31 to the required length, and the bolt 334 is fixed in place through the first L-shaped plate 31, the second L-shaped plate 32 and the outer sleeve 11. The support rod 331 is stretched, and the sliding rod 332 inside the support rod 331 moves to the required length. The base 336 on the shock absorber 335 is in contact with the ground. The bolt 334 is passed through the threaded hole 333, the sliding rod 332 and the support rod 331 and fixed. The bolt 334 passes through the base 336 and the ground to play a limiting role. Under the action of the shock absorber 335, it plays a buffering and shock-absorbing role.

[0031] Working principle: When using the bypass thrustless sleeve compensator with a double-layer sealing structure, the external power supply is connected. The housing assembly 1 ensures the normal operation of the bypass thrustless sleeve compensator. The double-layer sealing structure 2 provides a sealing effect, and the support structure 3 provides support.
