Description

TECHNICAL FIELD

[0001] The utility model belongs to marine diesel engine pipeline field, concretely relates to a marine diesel engine pipeline convenient to install. BACKGROUND

[0002] The reliability and installation efficiency of the connection of the marine diesel engine pipeline system as a key component of power transmission directly affect the safety and maintenance cost of the ship operation. The traditional marine pipeline is connected by welding, however, in the narrow space of the ship, although the welding connection is good in sealing, it is difficult to disassemble, which is not conducive to the later maintenance or component replacement. In addition, the ship is in complex working conditions such as vibration and corrosion for a long time, and the traditional connection structure is prone to problems such as loosening and leakage, which leads to the decrease of diesel engine efficiency and even safety hazards.

[0003] In the prior art, some improved pipeline connection structures try to simplify the installation steps through buckles or quick couplings, but often have defects such as poor centering and insufficient pressure resistance. The existing marine diesel engine pipeline is large in size, and due to the limitation of manufacturing process, there is usually a certain size deviation between the pipelines, which makes it difficult to successfully position the pipelines at one time, and the pipelines can be successfully installed only after multiple position adjustments. In addition, the surface of the existing marine diesel engine pipeline is relatively smooth, which is difficult to force, increasing the difficulty of installation. For example, although some guide rings can initially guide the insertion of the pipeline, they lack multi-stage limiting and reinforcing mechanisms, and are prone to displacement in a vibrating environment. In addition, the traditional reinforcing method is difficult to balance the installation convenience and sealing strength, especially in high-pressure oil lines, which is prone to sealing failure due to stress concentration.

[0004] Therefore, how to provide a new or otherwise improved connection structure of a marine diesel engine pipeline to alleviate or at least mitigate the above problems or defects is a problem that needs to be solved at present. INVENTION CONTENTS

[0009] The front end of the limiting assembly and the rear end of the guide assembly are provided with reinforcing assemblies, and the reinforcing assemblies comprise first reinforcing discs and second reinforcing discs arranged on the annular shell and the guide ring respectively, and are used for reinforcing and sealing the first pipeline and the second pipeline.

[0010] As a preferred technical scheme, two limiting blocks are symmetrically arranged in the annular limiting groove, the limiting blocks and the limiting holes are alternately distributed along the circumference of the annular shell, and the width of the guide block is smaller than the circumferential interval of the limiting hole.

[0011] As a preferred technical scheme, the outer diameter of the guide ring is gap-fitted with the inner diameter of the annular shell.

[0012] As a preferred technical scheme, the first reinforcing disc and the second reinforcing disc are both provided with coaxial corresponding threaded holes and are connected through bolts.

[0014] As a preferred technical scheme, the first pipeline and the second pipeline are both provided with pull rings, the axis direction of the pull ring is perpendicular to the pipeline axis direction, and the first pipeline and the second pipeline are pulled during installation.
