AI Technical Summary

Problems solved by technology

[0002] Bellows compensators are widely used in marine exhaust systems at this stage. Since bellows compensators need exhaust pipe length and exhaust temperature to calculate the amount of compensation and the amount of use, it is also necessary to calculate the amount of compensation based on the direction of the exhaust pipe, Arrangement positions such as bending radius and technical requirements further set a fixed installation position. Each type of ship needs to be designed separately, which is complex in design, difficult in installation, and high in construction costs. In addition, the bellows compensator is very easy to be damaged and broken. low safety performance

Embodiment Construction

[0032] The technical solutions in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. However, this should not be construed as limiting the present invention to specific embodiments, but only for explanation and understanding:

[0033] Such as figure 1 and figure 2 As shown, this embodiment provides a marine thermal expansion tube compensation device, including a first base body 1, a sliding tube 2, a second base body 3, a gland 7, a loose flange 4, a flat sealing ring 5 and a radial Sealing ring 6.

[0034] The first seat body 1 includes a first pipe body 101 and two flanges. The first pipe body 101 is in the shape of a round pipe and is made of stainless steel. The two flanges can be made of 20# steel or stainless steel. The flanges are respectively welded to both ends of the first pipe body 101 .

[0035] The sliding tube 2 is in the shape of a circular tube, and the outer diameter of the slidi...

Abstract

The invention discloses a marine thermal expansion pipe compensation device. The marine thermal expansion pipe compensation device comprises a first base body, a sliding pipe, a loose flange and a second base body which are sequentially installed. The first base body comprises a first pipe body, and flanges are arranged at two ends of the first pipe body. The outer diameter of the sliding pipe issmaller than the inner diameter of the first pipe body, one end of the sliding pipe extends into the first pipe body, and a sliding plate is arranged at the other end of the sliding pipe. An end coverused for installing the sliding plate is arranged at one end of the second base body, and a flange is arranged at the other end of the second base body. The loose flange is connected to the outer wall of the sliding pipe in a sleeving mode, and the flange, close to the sliding plate, on the first base body is connected with the loose flange. A plane sealing ring is arranged between the inner bottom face of the end cover and the end face of the sliding plate. A radial sealing ring is arranged between the loose flange and the sliding pipe. The problem that the coaxiality deviation and the disalignment requirement caused by working state changes are generated when an exhaust pipe is installed is solved, the service life is long, and the application cost is low.

Description

technical field [0001] The invention relates to the technical field of thermal compensation tube structure, in particular to a thermal expansion tube compensation device for ships. Background technique [0002] Bellows compensators are widely used in marine exhaust systems at this stage. Since bellows compensators need exhaust pipe length and exhaust temperature to calculate the amount of compensation and the amount of use, it is also necessary to calculate the amount of compensation based on the direction of the exhaust pipe, Arrangement positions such as bending radius and technical requirements further set a fixed installation position. Each type of ship needs to be designed separately, which is complex in design, difficult in installation, and high in construction costs. In addition, the bellows compensator is very easy to be damaged and broken. low safety performance. Contents of the invention [0003] The purpose of the present invention is to provide a marine therm...
