Description
The technical field is as follows:
the utility model relates to a welding pipe platform commonly used among high-voltage apparatus, concretely relates to high-voltage apparatus's sealed pipe platform.
Background art:
one end of the existing pipe stand 1 extends into a tank wall or a tank wall 4, if an outer pipeline 3 needs to turn, the existing pipe stand is generally connected with an elbow 2 and then connected with the outer pipeline 3, and if the existing pipe stand relates to turning, the elbow is generally welded on the pipe stand. In high-pressure equipment, welding is involved, but the high processing technology and the detection technology are high, and welding seam flaw detection is generally involved. As shown in fig. 1, after being connected with an elbow 2, the common pipe stand 1 structure has two welding seams 21 and 22, and one set of long storage tank and a conveying pipeline thereof can reach dozens or even hundreds, the pipe stand connection mode has the disadvantages of multiple welding times, multiple flaw detection processes, complex machining process and complex detection, and if the pipe stand can be formed at one time, the machining process and the detection process can be reduced.
For one-time pipeline bending, if the steel pipe is manufactured into the bent pipe by adopting a stretch bending process, the stretch bending process changes the material property of a metal material, the pipe wall at the bent pipe is inevitably thinned, and the bent pipe is not suitable for high-pressure equipment.
If the mould is opened to manufacture a standardized turning pipeline, the solution is not more suitable for non-standard products and the specificity of the non-standard products, and the standard part is difficult to adapt to the customized non-standard products.
The utility model has the following contents:
the utility model aims to solve the technical problem that effectively reduce the process number of times and the detection number of times in the pipe connection mode among the current high-voltage apparatus, reduce work load, reduce material and cost of labor, improve machining efficiency, provide a neotype pipe stand connected mode.
For solving above-mentioned technical problem, the present case utility model provides a technical scheme does: the utility model provides a sealed tube stage of high-pressure equipment, the one end of this sealed tube stage is sealed, and one end opening is provided with the pipeline interface on the pipe wall of this sealed tube stage, an external pipeline and this pipeline interface sealing connection.
The tube stand is a forged tube stand. The pipe table is a cast pipe table.
The interface is a circular hole; the external pipeline is a round pipe. The interface is a square hole; the external pipeline is a square pipe.
The pipe stand and the pipeline are steel pipes. The pipe stand is a double-wall pipe stand. The sealing connection mode is welding.
Due to the adoption of the technical scheme:
1. the pipe table is formed by one-time forging or casting, one end of the pipe table is closed, the other end of the pipe table is opened, a through hole is formed in the tank wall/the tank wall, the open end of the through hole extends into the through hole, the tank wall is welded with the pipe table, a side wall hole is formed in the side wall of the closed end of the pipe table, and the outer pipeline can extend into the side wall hole and is welded with the pipe table. Compared with the existing elbow connection mode of the pipeline, the connection mode of the pipe table type and the elbow connection mode of the pipeline reduces a welding seam and a flaw detection procedure;
according to statistics, in one high-voltage equipment/set, the number of the structures is dozens, even hundreds or hundreds, 1 welding line is not reduced for the connection mode, 1 flaw detection is reduced, and dozens, even hundreds or hundreds of welding lines and flaw detection procedures are reduced in the whole equipment/set.
The pipe stand structure connection mode of present case seems simple, has reduced the work load of machining process number of times, the number of times of detecting a flaw in fact by a wide margin, effectively reduces processing cost and detection cost.
2. If a plurality of pipelines are connected to the same pipe table, the processing procedures are saved more.
3. According to the understanding of ordinary technicians, if a pipeline turns, an elbow is preferred; the pipe stand and the connection mode belong to the extremely creative idea that the elbow pipe stand is provided with one end plugged, and the times of welding and flaw detection are greatly reduced due to the creative idea, so that the material cost and the labor cost are obviously reduced under the accumulative effect in the whole equipment, and the operation efficiency is greatly improved.
4. The pipe stand facilities are customized products, and compared with standard parts, the pipe stand facilities can better meet requirements on equipment design, such as various personalized requirements of installation, production processing, welding processes and the like.
