Description
Technical Field
The utility model relates to a be suitable for cutting ferrule formula reducing flange system structure that different latus rectum pipelines connect belongs to shipbuilding technical field.
Background
In the prior art, for a pipeline system of a ship, a steel pipe with the drift diameter being more than or equal to 15mm is usually connected with a copper pipe or a stainless steel pipe with the drift diameter being less than 15 mm. Currently, there are two common connection methods:
the first is to use galvanized steel pipe and through-the-cabin bayonet joint welding, but it requires later welding. If the pipeline system uses galvanized steel pipes, the later welding can damage the zinc layer of the pipeline, and the inner wall of the pipeline can not be repaired by coating, so that the corrosion of the pipeline can be accelerated; meanwhile, later welding occurs on the ship, and the welding space is not necessarily enough to carry out butt welding.
The second method is to use a flange to weld with a through cabin clamping sleeve joint, and although the method avoids various defects of the first method, the welding workload is only advanced to the position before ship loading. Welding work is still required and requires grinding and painting. If the pipeline system is processed by hot galvanizing, the clamping sleeve thread is possibly damaged in the hot galvanizing stage. If stainless steel materials which do not require surface treatment are used, a certain cost is added
For example, chinese patent with patent publication No. CN204828982U discloses a flanged steel skeleton cast nylon reducer pipe, which comprises a reducer pipe body, wherein flanges are arranged at two ends of the reducer pipe body, the reducer pipe body and the flanges are made of MC nylon material through one-time casting, and the reducer pipe further comprises a steel skeleton with the same shape as the reducer pipe body and the flanges, the steel skeleton is a metal plate with uniform hollowing, and the steel skeleton is wrapped in the MC nylon material forming the reducer pipe body and the flanges. The reducer pipe is lined with the steel skeleton in the nylon body, has a simple structure, is convenient to prepare, does not need special equipment, and can be produced by using the existing centrifugal casting equipment.
The pipe fitting provides the capability of reducing the diameter and has better pressure resistance, but because the pipe fitting needs one-step casting molding, corresponding production equipment is needed, and the production requirement is higher and the cost is higher.
If chinese patent with patent publication No. CN212319076U discloses a novel ferrule flange, which relates to the non-welded flange technical field, including flange plate and ferrule, flange-flange connecting thread through holes have been evenly opened between the left and right side walls of the flange plate with the central axis symmetry of the flange plate, the connection surface of the flange plate and ferrule protrudes towards one side of the ferrule, flange ferrule connecting thread blind holes have been evenly opened with the central axis symmetry of the flange plate on one side wall of the flange plate connected with the ferrule, the ferrule includes a flange connecting ring connected with the flange plate and a pipe connecting ring far away from one end of the flange plate, the flange connecting ring has been opened with ferrule flange connecting thread through holes, the pipe connecting ring has been opened with ferrule-pipe connecting thread through holes.
The device can be used for connecting the flange with the pipeline in a clamping sleeve fixing mode without welding operation, so that the flange is very convenient to install, overhaul and replace, and the technical problem that the pipeline can be connected under the condition that fire can not be objectively started is solved; but the problem of reducing diameter cannot be solved.
Therefore, in order to solve the above-mentioned background problems, it is urgent to develop a ferrule type variable diameter flange system structure suitable for connecting pipelines with different diameters.
