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 double-hinged 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. Utility Model Content

[0005] The utility model aims to provide a pipeline system composed of an L-shaped metal hose and a double-hinged compensator, so as to solve the problem that it is difficult to cope with large displacements in multiple random directions, which seriously affects the service life of the pipeline.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipeline system composed of an L-shaped metal hose and a double hinged compensator, comprising an L-shaped pipeline body, wherein the pipeline body comprises two vertically arranged straight pipes and an elbow installed between the two straight pipes, and is characterized in that: a hinge compensator and a metal hose are respectively arranged on the two straight pipes, the hinge compensator comprises a bellows and two end pipes, the two end pipes are respectively fixedly connected to the two ends of the bellows, and a hinged plate is rotatably installed on the outer wall of the end pipe.

[0007] Preferably, the outer walls of the two end tubes are respectively provided with vertical plates, the hinged plates are rotatably mounted on the outer walls on both sides of the vertical plates, and the corrugated tube is located between the two vertical plates.

[0008] Preferably, the hinge compensators are in two groups, wherein one group of the hinge compensators is fixedly connected to the elbow, and the other group of the hinge compensators is fixedly connected to the straight pipe.

[0009] Preferably, the metal hose comprises a connecting pipe, a second bellows and a pressure ring, both ends of the second bellows are fixedly connected to the connecting pipe, and the pressure ring is fixedly connected to the connection between the connecting pipe and the second bellows.

[0010] Preferably, one end of the connecting pipe is fixedly connected to the elbow, and the other end thereof is fixedly connected to the straight pipe.

[0011] Preferably, fixed supports are respectively fixedly installed on the outer walls of the two straight pipes, and a support bracket is fixedly connected to the outer wall of the elbow.

[0012] The technical effects and advantages of the utility model are as follows: through the lateral deflection of the metal hose, the large earthquake displacement from the horizontal pipe is absorbed, and through the hinge compensator, the large earthquake displacement from the vertical pipe is absorbed. The metal hose and the hinge compensator allow the pipeline body to have a certain moving space to increase the pipeline body's ability to cope with displacement during an earthquake and ensure its use. Support brackets are arranged at the elbows to withstand the weight of the pipeline body and ensure that the pipeline can be moved in any direction, thereby ensuring that the pipeline is not damaged when subjected to an earthquake impact.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 The pipe system of an L-shaped metal hose and a double hinge compensator combination shown in the figure comprises an L-shaped pipe body 1, the pipe body 1 comprises two vertically arranged straight pipes 11 and an elbow 12 installed between the two straight pipes 11, and the two straight pipes 11 are respectively provided with a hinge compensator 2 and a metal hose 3. There are two fixed supports 5, and the two straight pipes 11 are respectively fixedly connected to the fixed supports 5. The pipeline body 1 is composed of two mutually perpendicular straight pipes 11 and an elbow 12. The seismic isolation wall is set in the seismic isolation layer. The pipeline body 1 is fixedly installed on one side of the seismic isolation wall through a fixed support 5, and one end of the pipeline body 1 extends to the other side of the seismic isolation wall. The straight pipe 11 is respectively provided with a metal hose 3 and a hinge compensator 2. When the metal hose 3 is located on the vertical straight pipe 11 and the hinge compensator 2 is located on the relatively horizontal straight pipe 11, during an earthquake, the lateral deflection of the metal hose 3 will absorb the large seismic displacement from the horizontal pipe, and the hinge compensator 2 will absorb the large seismic displacement from the vertical pipe. The metal hose 3 and the hinge compensator 2 are used to give the pipeline body 1 a certain moving space to increase the pipeline body 1 to cope with the displacement during an earthquake and ensure its use. The support bracket 4 is fixedly connected at the elbow 12. While bearing the weight of the pipeline body 1, it can ensure that the pipeline body 1 can move in any direction and ensure that the pipeline body 1 is not damaged when it is impacted by an earthquake.

[0021] Specifically, the metal hose 3 includes a connecting pipe 31, a second bellows 32 and a pressure ring 33. Both ends of the second bellows 32 are fixedly connected to the connecting pipe 31, and the pressure ring 33 is fixedly connected to the connection between the connecting pipe 31 and the second bellows 32. One end of the connecting pipe 31 is fixedly connected to the elbow 12, and the other end thereof is fixedly connected to the straight pipe 11. Figure 2 and Figure 4As shown, connecting flanges are provided at both ends of the connecting pipe 31, which are fixedly connected to the elbow 12 and the straight pipe 11 through the connecting flanges, and a mesh sleeve is provided on the outer wall of the bellows 32 to protect the bellows 32. When impacted, the bellows 32 is deformed by force, and the mesh sleeve provided on the outer wall of the bellows 32 is also deformed accordingly, but the pressure rings 33 provided at both ends are always fixedly connected to the connecting pipe 31, so that the metal hose 3 and the elbow 12 and the straight pipe 11 always maintain a stable connection relationship, and the horizontal force from the outside is dispersed to ensure the use of the pipeline body 1. The integrity of the pipeline body 1 is ensured by ensuring the integrity between the straight pipe 11 and the horizontal pipe, and the anti-seismic effect is improved through the metal hose 3 and the hinge compensator 2.

[0022] Specifically, the hinge compensator 2 includes a bellows 21 and two end tubes 22. The two end tubes 22 are fixedly connected to the two ends of the bellows 21, and the outer wall of the end tube 22 is rotatably mounted with a hinge plate 23. The outer walls of the two end tubes 22 are respectively provided with vertical plates 24, and the hinge plates 23 are rotatably mounted on the outer walls of the vertical plates 24 on both sides. The bellows 21 is located between the two vertical plates 24. The hinge compensator 2 is divided into two groups, one of which is fixedly connected to the elbow 12, and the other is fixedly connected to the straight pipe 11. Please refer to Figure 3 and Figure 5 As shown, there are two groups of hinge compensators 2, and flanges are respectively provided at both ends of the hinge compensators 2. The hinge compensators 2 are fixed between the straight pipe 11 and the elbow 12 by the flanges, and the hinge compensators 2 are adjacently arranged on the horizontal pipe. A bellows 21 is arranged between the end pipes 22. When subjected to a force perpendicular to the horizontal pipe, the bellows 21 will be offset by the force, with the straight pipe 11 as the base point, and move in the direction of the force. When the hinge plate on the vertical plate 24 moves, the connection angle between the hinge plate and the bellows 21 is also deflected to meet the actual moving angle, and the fixed support 5 and the support bracket 4 on one side are driven to offset, and the metal hose 3 located in the vertical direction is also deformed accordingly, so that the pipeline body 1 can be adjusted in time when subjected to force, thereby improving the seismic isolation capability.

[0023] Specifically, the outer walls of the two straight pipes 11 are respectively fixedly installed with fixed supports 5, and the outer wall of the elbow 12 is fixedly connected with a support bracket 4. The pipeline body 1 is L-shaped, in which one straight pipe 11 is perpendicular to the seismic isolation wall, and one end thereof passes through the outer walls on opposite sides of the seismic isolation wall and extends to the upper side of the seismic isolation wall. The support bracket 4 can be a sliding support or a spring support bracket 4. The specific use can be based on the position of the pipeline body 1 in the seismic isolation layer. Through the movable support bracket 4, the elbow 12 can adjust its position accordingly when the straight pipes 11 on both sides are stressed, so as to facilitate use.

[0024] Working principle: When an earthquake occurs, the L-shaped pipe body 1 in the seismic isolation layer will produce a large displacement of 360° in any direction. The metal hose 3 and two sets of hinge compensators 2 absorb the displacement in the horizontal and vertical directions respectively. At the same time, the support bracket 4 on the elbow 12 bears the weight of the straight pipe 11, and transmits the seismic displacement in different directions together with the elbow 12, which can cope with large earthquake displacement in any direction of 360°, increase seismic resistance and ensure use.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
