Abstract
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 double hinge and a large pull rod compensator. Background Art
[0002] Pipes are like the blood vessels of a building. Structural seismic isolation is promoting the standardized development of seismic isolation flexible pipe technology. The flexible treatment of pipes passing through isolation layers and crossing isolation joints (trenches) is the most typical and important structural measure. It can ensure that the building can continue to serve with little repair after the earthquake, 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 isolation layers and crossing 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 in stiffness of the pipe flexible elements, which can easily 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 compensating for large and random earthquake displacements 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 limited, 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.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The utility model provides Figure 1 、 23 shows a pipeline system composed of an L-shaped double hinge and a large tie rod compensator, comprising an L-shaped pipeline body 1, wherein the pipeline body 1 comprises two vertically arranged straight pipes 11 and an elbow 12 installed between the two straight pipes 11, and is characterized in that: a hinge compensator 2 and a large tie rod compensator 3 are respectively provided on the straight pipes 11, and the large tie rod compensator 3 comprises a connecting pipe 31, a tie rod body 32 and a bellows 33, wherein the bellows 33 is symmetrically installed on the connecting pipe 31, one end of the connecting pipe 31 is fixedly connected to the elbow 12, and the tie rod body 32 is installed on the connecting pipe 31 via a spherical and conical washer. The bellows 33 is fixedly connected to the connecting pipe 31, and an end plate 34 is provided on the connecting pipe 31, and the tie rod body 32 is connected to the end plate 34 via a spherical and conical washer. Two mutually perpendicular straight pipes 11 are connected by an elbow 12 to form an L-shaped pipe body 1, wherein one straight pipe 11 is arranged perpendicular to the seismic isolation wall, and one end passes through the seismic isolation wall. The straight pipe 11 is fixed by a fixed support 4, thereby achieving the fixation of the pipe body 1, and the fixed connection support 5 on the elbow 12 is used to fix the straight pipe through the fixed support to bear the weight of the pipe system, while ensuring the displacement stroke freedom of the pipe in any direction, and dispersing the horizontal and vertical forces through the hinge compensator 2 and the large pull rod compensator 3 along the direction of the force, so as to ensure that the pipe body 1 improves its ability to cope with impact force and pulling force for normal use; a hinge compensator 2 is set on one straight pipe 11, and a large pull rod compensator is set on the other straight pipe 11 Compensator 3, when the straight pipe 11 where the hinge compensator 2 is located is set vertically, the large tie rod compensator 3 is set horizontally. At this time, when the tie rod compensator 3 is subjected to vertical and horizontal forces, a spherical or conical washer 35 will be set on the tie rod body 32. Through the washer 35, when the connecting pipe 31 is deformed by the force of the bellows 1 33, the large tie rod compensator 3 absorbs the large seismic displacement from the vertical position of the pipeline body 1. The hinge compensator 2 uses the bellows 2 22 to make the straight pipe 11 located in the two middle pipes 21 shrink on one side when subjected to horizontal forces, and drive the hinge plate 24 to rotate and adjust to the corresponding angle. The hinge compensator 2 absorbs the large seismic displacement from the horizontal position of the pipeline body 1, thereby extending the service life of the pipeline body 1.
[0022] Specifically, the washer 35 is a spherical or conical washer, and the end of the connecting pipe 31 opposite to the elbow 12 is fixedly connected to the straight pipe 11. Figure 5As shown, the tie rod body 32 is connected to the end plate 34 through a washer 35. When the straight pipe 11 provided with the large tie rod compensator 3 is impacted, the large tie rod compensator 3 will deform through the two bellows 33 angles, driving the tie rod body 32 provided on the outer wall of the connecting pipe 31 to rotate in a certain direction along with the direction of the force to adapt to the offset angle of the two bellows 33, so as to absorb the large earthquake displacement from the vertical position of the pipeline body 1, and can move vertically along the direction of the force to avoid damage to the straight pipe 11 caused by the force.
[0023] Specifically, the hinge compensator 2 includes an intermediate tube 21, a second bellows 22 and a vertical plate 23. The second bellows 22 is fixedly mounted on the intermediate tube 21. The vertical plate 23 is fixedly mounted on the outer wall of the intermediate tube 21 and is located on both sides of the second bellows 22. A hinge plate 24 is provided on each of the two vertical plates 23, and the two hinge plates 24 are rotatably connected. The hinge compensators 2 are divided into two groups, one group of which is fixedly connected to the elbow 12, and the other group of which is fixedly connected to the straight pipe 11. With the straight pipe 11 as the base point, the state of the two groups of hinge compensators 2 when absorbing large earthquake displacements in the horizontal position can be referred to the attached figure. Figure 4 As shown, the two bellows 22 will be matched with the hinge plate 24, and the bellows 22 will be deformed at a certain angle. The hinge plate 24 on the bellows 22 will rotate at a certain angle to adapt to the movement of the two bellows 22. At this time, the pipe body 1 can refer to the attached Figure 5 As shown, two sets of hinge compensators 2 are used in conjunction to disperse the impact force on the straight pipe 11, and the hinge compensators 2 are fixed to the straight pipe 11 by means of flanges and connected to the elbow 12, so that when the straight pipe 11 is subjected to impact force, the hinge compensators 2 can move horizontally in the direction of the force to avoid damage to the straight pipe 11 caused by the force.
[0024] Specifically, fixed supports 4 are fixedly mounted on the outer walls of the two straight tubes 11, and a support bracket 5, which is a sliding support or a spring hanger, is fixedly connected to the outer wall of the elbow 12. The sliding support or spring hanger allows the elbow 12 to adjust its position when any straight tube 11 is impacted, ensuring that the L-shaped piping system can move freely when any straight tube 11 is impacted, thereby protecting the piping system from damage caused by the impact.
[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
