Symmetrical hyperboloid vibration reduction connecting pipe for combined flanges with self-locking function and manufacturing method

Abstract

The invention discloses a symmetrical hyperboloid vibration reduction connecting pipe for combined flanges with a self-locking function and a manufacturing method. The vibration reduction connecting pipe comprises a symmetrical hyperboloid flexible pipe body, an intermediate constraint ring and two self-locking type combined flanges, the middle of the symmetrical hyperboloid flexible pipe body issleeved with the intermediate constraint ring, and the two ends of the symmetrical hyperboloid flexible pipe body are correspondingly provided with the self-locking type combined flanges and connectedwith the corresponding self-locking type combined flanges in a locking fit mode. The vibration reduction connecting pipe has the comprehensive properties such as the high pressure resistance, the fatigue resistance, the low rigidity, the high displacement compensating capacity and the excellent vibration reduction property; and through the self-locking type combined flanges, self-locking of a skeleton layer body is achieved when the pipe body is pressed, the rewinding skeleton layer forms an anti-fatigue buffering layer between the inner walls of locking flanges and the pipe body, fastening parts rewinding a skeleton material are locked through clamping grooves between sealing flanges and the locking flanges when the sealing flanges and the locking flanges compress the skeleton material in the working process, and a high-reliability locking anti-pulling function is achieved.

Description

technical field [0001] The invention relates to the field of pipe joints of pipelines leading to the sea, in particular to a symmetrical hyperboloid vibration-damping joint with a self-locking function combined flange and a manufacturing method thereof. Background technique [0002] In the design of modern ships, vibration reduction and noise reduction has been an important technical problem that has been difficult to solve for a long time. attention of the technology industry. The main element of seawater pipeline vibration reduction is the vibration-damping connection connecting equipment and seawater pipeline. As an important damping component in seawater pipelines, the damping joint has technical requirements such as large displacement compensation capability, excellent vibration damping performance, and high reliability. In some more important and complex parts, it also needs to have low stiffness and balance, etc. special performance. [0003] In the course of the d...

AI Technical Summary

Problems solved by technology

Among them, CKXT marine flexible single-ball rubber joints and CKST marine flexible double-ball rubber joints have low rigidity and good vibration damping effect, but their safety and reliability are poor, and they are not suitable for important pipeline systems with high pressure levels; Metal bellows and PXG balanced vibration damping joints have poor displacement compensation and vibration damping performance, and are not suitable for piping systems with high requirements for displacement compensation and vibration damping

In addition, there are some newly developed high-performance vibration-absorbing connectors with large displacement compensation capabilities and high reliability, but generally have high rigidity, which will be limited to a certain extent in the military application of important naval seawater pipelines in the future.

[0004] With the rapid development of modern acoustic stealth technology, new types of important ships have greatly increased the requirements for vibration reduction and noise reduction of sea-through pipelines. Comprehensive technical performance such as vibration damping performance, it is difficult for existing domestic and foreign related technical products to have the above performance characteristics
