Description

Technical Field

[0001] The utility model belongs to the technical field of flexible pipelines, and in particular relates to a pipeline system composed of an L-shaped metal hose and a large pull rod compensator. Background Art

[0002] Pipelines are like the blood vessels of a building. Structural seismic isolation is giving rise to the standardized development of seismic isolation flexible pipe technology. The flexible treatment of pipes that pass through seismic isolation layers and cross seismic isolation joints (trenches) is the most typical and important structural measure, which can ensure that the building can continue to serve without much repair after the earthquake, thereby minimizing the impact of earthquakes on people's normal lives.

[0003] Traditional pipe flexible parts are basically only used to absorb the thermal expansion and contraction deformation of the pipe. The deformation is small and the deformation process is slow, which is equivalent to quasi-static deformation. In recent years, with the increasing application of seismic isolation technology in the construction field, the problem of seismic isolation of pipes passing through seismic isolation layers and crossing seismic isolation joints has become prominent. Pipe seismic isolation must be achieved through flexible elements; the increase in the allowable deformation capacity of flexible elements will inevitably lead to an increase in the length and reduction of the stiffness of the flexible elements of the pipe, which is very likely to cause columnar stability problems of the flexible elements. In addition, the displacement direction of an earthquake is unpredictable, and the deformation capacity of the seismic isolation flexible parts must meet the preset displacement in any direction. Usually, the pipes in a building are densely distributed and the space is small. How to solve the problem of large and random earthquake displacement compensation in a small space has always been a technical problem.

[0004] In summary, in the existing technology, when responding to earthquakes, the pipeline's ability to cope with deformation is relatively single, and it is difficult to cope with displacements in multiple random directions, which seriously affects the service life of the pipeline and needs to be solved.

A mesh sleeve 24 is fixedly installed on the outer wall of the bellows 1, and flanges 25 are provided at both ends of the connecting pipe 21. The flanges 25 are fixedly connected to the pipeline body 1. One end of the connecting pipe 21 is fixedly connected to the elbow 12, and the other end is fixedly connected to the straight pipe 11. Please refer to the attached Figure 2As shown in or 4, flanges 25 are provided at both ends of the connecting pipe 21, which are fixedly connected to the elbow 12 and the straight pipe 11 through the flanges 25, and a mesh sleeve 24 is provided on the outer wall of the bellows 22, and the bellows 22 is protected by the mesh sleeve 24. When impacted, the bellows 22 is deformed by force, and the mesh sleeve 24 provided on the outer wall of the bellows 22 is also deformed accordingly, but the pressure rings 23 provided at both ends are always fixedly connected to the connecting pipe 21, so that the metal hose 2 always maintains a stable connection relationship with the elbow 12 and the straight pipe 11, and deforms with the horizontal force from the outside, and disperses the force to the large pull rod compensator 3 through the support bracket 4, so as to ensure the integrity of the pipeline body 1, maintain the use state, and improve the seismic effect.
