Embodiment Construction

[0022] The invention provides a flexible compensation mechanism for marine seawater pipelines, which can realize flexible compensation, relieve pipeline vibration, reduce noise, and have wide applications. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 with figure 2 As shown, the present invention provides a ship seawater pipeline flexibility compensation mechanism, including a sleeve 10, two connecting pipes 20 and a compensation device. The two connecting pipes 20 have the same central axis, and there is a buffer space between the two connecting pipes 20; the sleeve 10 is arranged on the outer circumference of the two connecting pipes 20; the compensation device includes a flange plate fixed on the two connecting pipes 20 30 , an annular fixing plate fixed on the inner wall of the casing 10 , and an elastic flexible body 40 adhered between the flange plate 30 and the...

Abstract

The invention discloses a ship seawater pipeline flexible compensation mechanism which comprises sleeves, two connecting pipes and compensation devices. The two connecting pipes have identical centralaxes and are separated from each other by cushion distances; the sleeves are arranged on the outer peripheries of the two connecting pipes; the compensation devices comprise flange plates, annular fixing plates and elastic flexible bodies, the flange plates are fixed onto the two connecting pipes, the annular fixing plates are fixed onto the inner walls of the sleeves, and the elastic flexible bodies are adhered between the flange plates and the fixing plates. The ship seawater pipeline flexible compensation mechanism has the advantages that the elastic flexible bodies are arranged between the flange plates and the fixing plates, accordingly, the stress levels of pipelines can be effectively lowered, pipeline vibration generated by equipment or fluid excitation can be effectively consumed, and the noise levels of the pipelines can be lowered; the flange plates are arranged on the inner sides of the fixing plates and can be compressed to the fixing plates under internal pressures of fluid in the pipelines, and accordingly the ship seawater pipeline flexible compensation mechanism has a self-sealing characteristic; the ship seawater pipeline flexible compensation mechanism is easy and convenient to manufacture and mount, low in cost and extensive in application range.

Description

technical field [0001] The invention relates to a ship pipeline, in particular to a flexible compensation mechanism for a ship seawater pipeline. Background technique [0002] Pipelines are widely used in the shipbuilding industry, mainly connected to various mechanical equipment, and play the role of working medium transportation and energy transmission. When the mechanical equipment undergoes thermal expansion or is displaced by external force, the pipeline interface will be displaced. Exceeding the allowable displacement will cause damage to the pipeline structure, especially for seawater pipelines. Once a breach occurs, the seawater will be massive. Enter the cabin, causing an irreparable accident. [0003] In order to realize displacement compensation, an elbow structure is usually set up in the industry, and port displacement compensation is performed through the flexibility of the pipeline itself. However, this method has limited compensation ability and requires a ...
