Description
Technical field
The application relates to the various high-temperature high-voltage reaction devices in petroleum refining and chemical industry, Coal Chemical Industry, chemical fertilizer industry and other various chemical industry, air-conditioning, air cooling, electric power facility equipment etc. or technical field of heat exchangers, there is load cycle or pressure vessel turnover material opening fluidization adapter flange that operating parameter often fluctuates and pressure vessel thereof particularly to a kind of.
Background technology
Mouthpiece is had on vessel shell, different by the size of container technological parameter and the difference of adapter function, joint pipe structure.Owing to pressure vessel operates the most at high temperature under high pressure, or there is circulation repeatable operation, so mouthpiece must have lasting high intensity and excellent sealing.
The mouthpiece of traditional pressure vessel, is only adding wall thickness with one section of the case weld of pressure vessel.When specification is not standard size needed for thick-walled pipe, use the thick-walled pipe of close specification to process, or use forging manufacture.
Traditional pressure vessel opening adapter as shown in Figure 1, the housing 1 of pressure vessel is had the mouthpiece 3 of heavy wall strengthening segment 2 by angle welding 4 assembly welding, is right-angle structure 5 at housing 1 inwall of pressure vessel in mouthpiece 3.Said structure there is problems in that one is to bear intrinsic pressure effect, not endurance；Two is owing to being a right-angle structure 5 at the inwall of the housing 1 of pressure vessel in mouthpiece 3, will gather material, and viscous fluid easily blocks.
Additionally, prior art has and will be improved to conical structure at the inner walls of pressure vessel in mouthpiece, its cone angle is determined by the Self-locking angle of material, material will not be gathered, but this structure is the conical structure of whole circumference, not only decrease the effective metal at the inner walls of pressure vessel in hole, also the effective thickness minimizing with conical structure inner surface bottom bolt hole is made, substantially weaken the intensity of adapter flange, to equipment safety operation potential threat, if by improving the intensity that the strength of materials makes up the adapter flange of weakening, not only make, between adapter flange and the housing of pressure vessel, Dissimilar Steel Welded Joint occurs, quality is difficult to ensure, and occur in that the physical property difference between two kinds of connectors and mechanical property difference, it is unfavorable for endurance, also add manufacturing cost.The structure appearance easily forming surface weakens excessively, and actual stealthy stiffness difference widens, and the disadvantages outweigh the advantages.
Therefore, research and develop attachment structure between the adapter of material opening and the vessel shell that are applied to petrochemical industry reactor of a kind of cost-effectiveness requirement can simultaneously taken into account by the requirement of intrinsic pressure, endurance, the not technology such as putty, easy welding and low cost and there is important engineering significance.
