Embodiment Construction

[0016] Such as figure 1 As shown, a multi-directional vibration damping device for conveying fluid pipelines includes: an outer shell 1, an end cover A2, a miniature shock absorber, an inner shell 7, a cover plate 8, a connecting plate 9, bolts 10, nuts 11 and washers 12. The shell 1 described above is in the shape of a half cylinder, made of steel pipes, the diameter of which matches the outer diameter of the pipeline to be damped, and the length is 40-300 mm, and parallel miniature shock absorbers are installed inside.

[0017] Such as figure 2 As shown, the shape of the end cap A is half a ring, the outer diameter of the ring is equal to the inner diameter of the outer shell 1, the inner diameter of the ring is equal to the outer diameter of the inner shell 7, and the thickness is 2-10 mm. Between the inner circles, several through holes are evenly distributed along the circumferential direction, the diameter of the through holes is equal to the diameter of the steel wire...

Abstract

The invention discloses a multidirectional vibration damping device for a fluid conveying pipeline. The multidirectional vibration damping device comprises two parts which are the same in structure. Each part comprises an outer shell, an end cover A, minitype absorbers, an inner shell, a cover plate and a connecting plate, wherein the multiple minitype absorbers are arranged in an inner cavity of the outer shell; each minitype absorber comprises steel wires, end covers B, a cylinder and steel balls, wherein the end covers B are welded to the cylinder, the steel balls are arranged in the cylinder, and the two steel wires are welded to the two end covers B respectively; the steel wires are welded to the end cover A so that the end cover A, the outer shell and the inner shell can be welded into a whole; the cover plate seals an inner cavity formed by the end cover A, the inner shell and the outer shell and is welded to the end cover A, the inner shell and the outer shell into a whole; and the connecting plate and the cover plate are a whole. The inner shells of the two parts of the multidirectional vibration damping device are tightly attached to the outer wall of the pipeline, the connecting plates are fastened together by thread fastening pieces, and vibration attenuation for the pipeline is achieved. The multidirectional vibration damping device is simple in structure, convenient to use, capable of reducing radial vibration and axial vibration of the pipeline and suitable for space pipeline vibration attenuation.

Description

technical field [0001] The invention relates to a pipeline damping device, in particular to a multi-directional damping device for a fluid transport pipeline. Background technique [0002] Pipeline transportation of fluid is an economical and convenient way of transportation, which plays an important role in the transportation of hot and cold water, oil, natural gas and other fluids, and is widely used in various industrial devices and living facilities. The flow of fluid in the pipeline will produce complex vibration phenomena, especially the heat medium flowing in the pipeline, such as the northern heating hot water, where liquid and gas are mixed, and the temperature changes greatly, which will induce pipeline vibration. In addition, when the diameter of the pipeline changes The part is prone to fluid-solid coupling resonance phenomenon, which makes the vibration increase rapidly. Affected by the building or geographical location, the pipe network is complex, and there a...
