AI Technical Summary
Existing expansion joints cause the rubber sleeve to deform and the fluid pressure to drop when the fluid pressure increases, making it difficult to accurately control the fluid pressure. They are especially unsuitable for pipelines with high fluid pressure requirements.
A pressure adjustment device is used between the rubber sleeve and the limiting shell. By adjusting the bolts and the limiting plate, the deformation range of the rubber sleeve is limited, thus ensuring stable fluid pressure.
It effectively limits excessive deformation of the rubber sleeve, avoids excessively low fluid pressure, and ensures stable fluid pressure output, making it suitable for pipelines with high fluid pressure requirements.

[0010] After the fluid pipeline is loaded with the utility model, if the pipeline needs to avoid the rubber sleeve body from deforming too much to affect the pressure of the outflow fluid, the limiting plate can be inwardly extruded by rotating the adjusting bolt, so that the limiting plate is shrunk, and then when the fluid pressure is applied to the rubber sleeve body, the excessive deformation of the rubber sleeve body can be limited by the smaller limiting plate, so that the influence of the deformation of the rubber sleeve body on the fluid pressure of the pipeline is reduced, and the output fluid pressure is prevented from being too low.
