Embodiment Construction
[0024] The present invention will be further described below in conjunction with specific embodiment:
[0025] Such as figure 1 , 2 , 3 and 4, a vibration-damping ship pipeline T-joint, including a T-shaped pipeline 10, the T-shaped pipeline 10 is provided with a joint housing, the joint housing is divided into an outer shell 1 and an inner The shell 2, the shell 1 is an equally divided wave structure; the wave crest of the wave shell is provided with a vertical spring 4 perpendicular to the shell, the vertical spring 4 is connected with the connecting ring 6, and the vertical spring 4 is provided with an adjustable elastic on the outside of the shell. The bolt 8; the connecting piece 7 is perpendicular to the inner shell 2, and the connecting piece 7 is provided with a connecting ring 6, which is connected by a parallel spring 5, and the parallel spring 5 is parallel to the inner shell; The partition 3, the transverse partition 3 is connected with the parallel spring 5; the...

The invention discloses a shock absorption ship pipeline T-joint which comprises a T pipeline. A joint shell is arranged outside the T pipeline and is divided into an outer shell body and an inner shell body. The outer shell body is of an equally-divided wavy structure. A perpendicular spring perpendicular to the outer shell body is arranged on the peak of the wavy outer shell body and connected with a connecting ring. A bolt for adjusting the tightness is arranged at the position, outside the outer shell body, of the perpendicular spring. A connector is perpendicular to the inner shell body and provided with a connecting ring. The connecting rings are connected through a parallel spring which is parallel to the inner shell body. A transverse partition plate is arranged in the joint shell and connected with the parallel spring close to the middle. When the pipeline is hit to shake, the spring in the T-joint shell and the wavy outer shell body have an effect on reducing the displacement and stress in the perpendicular direction, the transverse direction and the longitudinal direction of the joint, and the vibration displacement of the whole pipeline is reduced.
Description
technical field [0001] The invention relates to a pipeline vibration damping device, in particular to a vibration damping ship pipeline T-shaped joint. Background technique [0002] Ships will inevitably face collision problems during their operation, which is directly related to the vitality of ships. There are many pipeline systems on ships, and the pipeline system is mainly used to transport various fluid media and its accessories, pumps, monitoring instruments and valves. The pipeline system includes: pipelines, fittings (such as elbows, reducers, branch pipe connections, etc.), flanges, gaskets, bolted connections, valves, pipeline supports and hangers, and pumps. Under the normal working conditions of the system, these supports can meet the thermal deformation and static stress requirements of the pipeline. However, except for the rigid and guide hangers, most of the spring hangers on the pipeline will deform and increase with the increase of external force. Large, i...
