Description

Technical Field

[0001] The invention relates to a novel rotatable flange for a container ship and an installation method thereof, and belongs to the technical field of ship design. Background Art

[0002] Some piping systems have high requirements for the installation angle of the pipeline. Due to the limitation of the bolt hole position, the traditional flange may not be able to flexibly adjust the angle during installation. The bolt holes of the traditional flange are fixedly distributed, which requires the connected pipeline to be docked at a specific angle. For example, in some complex pipeline layouts, if two adjacent sections of pipeline need to be connected at a non-standard angle (not the common 90 degrees, 180 degrees, etc.), it is difficult for traditional flanges to meet such precise angle installation requirements. Because once the bolt holes cannot be aligned, the connecting bolts cannot be installed normally, and forced installation may cause the flange to be poorly sealed and leak. Safety hazards such as leakage. Moreover, in some occasions with limited space, such as the pipeline system inside the ship, the fixed angle installation method of the traditional flange may lead to unreasonable pipeline layout, occupy too much space, and even affect the installation and maintenance of other equipment.

[0003] At present, flanges are fixed by bolt holes on the flange surface. The adjustable angle of the pipeline during installation is limited, which is equivalent to the angle between the bolt holes, so the installation angle of the pipeline cannot be accurately controlled during installation. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a new type of rotatable flange for a container ship and an installation method. The flange includes a flange body and a rotating flange plate. The installation angle can be controlled by relative rotation between the rotating flange plate and the flange body.

[0005] The technical solution adopted by the present invention is: a new type of flange with a rotatable angle for container ships, the flange comprises a flange body and a rotating flange plate, the outer periphery of the flange body is provided with a flange body outer boss, the upper and lower sides of the flange body outer boss are respectively provided with a flange body upper outer ring and a flange body lower outer ring, and the interior of the flange body is provided with a flange body inner wall surface for welding with a pipeline;

[0006] The inner side of the rotating flange is provided with a flange inner groove, and the upper and lower sides of the flange inner groove are respectively provided with a flange upper inner ring and a flange lower inner ring, and the flange inner groove matches with the outer boss of the flange body;

[0007] The rotating flange comprises more than two groups of split flanges, which are combined into a complete annular flange, and the split flanges are connected by a flange body weld;

[0008] A ring-disk weld is provided between the upper outer ring of the flange body and the upper inner ring of the flange plate, and a ring-disk weld is provided between the lower outer ring of the flange body and the lower inner ring of the flange plate;

[0009] Bolt holes are arranged on the rotating flange.

[0010] The rotating flange comprises two separate flanges, a first flange and a second flange, and the first flange and the second flange are connected via a flange body weld.

[0011] A method for installing a new type of rotatable flange for a container ship comprises the following steps:

[0012] S1. Weld the end of the pipe to the inner wall of the flange body;

[0013] S2. When connecting the pipeline, the first flange and the second flange of the rotating flange are respectively installed on the flange body, and the outer boss of the flange body is inserted into the inner groove of the flange;

[0014] S3, welding the first flange and the second flange to form a flange body weld;

[0015] S4. Rotate the rotating flange, rotate the rotating flange and the flange body relative to each other, find the appropriate installation angle of the pipeline, and then connect the bolts through the bolt holes of the rotating flange to the flange of the connecting pipeline;

[0016] S5. Weld the outer ring on the flange body to the inner ring on the flange plate, and weld the lower outer ring on the flange body to the lower inner ring on the flange plate.

[0017] Compared with the prior art, the present invention has the following advantages: some pipeline systems have high requirements for pipeline installation angles. Due to the limitation of the bolt hole position, it is difficult to accurately control the installation angle of the pipeline in traditional flanges. The flange includes two parts: a flange body and a rotating flange. The installation angle can be controlled by the relative rotation between the rotating flange and the flange body. After the rotating flange is rotated and the relative rotation between the rotating flange and the flange body is found to have a suitable installation angle for the pipeline, the bolts are passed through the bolt holes of the rotating flange to connect with the flange of the connecting pipeline; then the outer ring on the flange body is welded to the inner ring on the flange, and the lower outer ring of the flange body is welded to the lower inner ring of the flange. The flange has a simple principle, is convenient and practical to install, and greatly improves the flexibility of pipeline installation on the basis of meeting the pipeline connection requirements. It has a good application effect and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS
