Abstract
The utility model discloses a high-pressure integrated multi-layer binding container. The high-pressure integrated multi-layer binding container comprises a spherical head and a barrel. The barrel is formed by an inner barrel and a binding layer board. A spherical head end portion, which is welded with the barrel, is in a stepped shape. A step possesses an extended straight edge, wherein the step is formed by combining and welding the spherical head and the inner barrel of the barrel. A height of the extended straight edge is 20-40mm. The structure of the high-pressure integrated multi-layer binding container is simple. During a making process, a postweld heat treatment does not need to be performed on the spherical head and a welded joint of the inner barrel. Production cost is reduced and a production period is shortened.
Description
Technical field
The utility model relates to a kind of pressurized container, especially a kind of high-pressure bottle of integral multi-layered wrapping.
Background technique
Integral multi-layered binding vessel has been cancelled the depth hoop welded joint in the multilayer binding vessel of sectional forming, has eliminated the influence to pressurized container of category-B welded joint that the whole wall thickness in this edge connects, the Security that has improved multilayer binding vessel.The process of manufacturing of integral multi-layered binding vessel is earlier inner core and two ends end socket assembly welding to be formed the inner housing of container and carry out integrated stress heat treatment, carries out the laminated board dressing that welded joint is evenly staggered again.In order to improve the bearing capacity of whole binding vessel, in the whole binding vessel of high pressure, adopt the dome head design usually, according among the GB150.1-2011 about the principle of classification of welded joint; It is the category-A welded joint that the dome head of the whole binding vessel of this high pressure and inner core weld formed circular weld, and according to the relevant regulations requirement of welding about inner core among the GB150, inner core category-A welded joint should be done postweld heat treatment; Therefore; Behind dome head and inner core assembly welding, must to do heat treatment, because the weight and the length of this type of whole binding vessel are all bigger to welded joint; Therefore; Have the heat treatment performance difficulty, the cost of processing is higher, and in heat treatment process, causes defectives such as inner core distortion easily.
The model utility content
The technical problem that model utility will solve: the defective to above existing technology provides a kind of high pressure integral multi-layered binding vessel; The integral multi-layered binding vessel of this high pressure is simple in structure; In working process, need not the welded joint of dome head and inner core is done postweld heat treatment; Reduce cost of production, shortened the manufacture cycle.
The technological scheme that the technical solution problem is taked: the integral multi-layered binding vessel of a kind of high pressure; Comprise dome head, cylindrical shell; Cylindrical shell is made up of inner core and wrapping laminate, and the end of dome head and cylindrical shell welding is a stepped shaft, and the one-level ladder of dome head and cylindrical shell inner core assembly welding has the prolongation straight flange.
Improvement as the utility model: the height that prolongs straight flange is 20-40mm.
Beneficial effect: the integral multi-layered binding vessel of the high pressure of the utility model, owing to adopted the integral multi-layered binding vessel of said high pressure to comprise dome head, cylindrical shell, cylindrical shell is made up of inner core and wrapping laminate; The end of dome head and cylindrical shell welding is a stepped shaft; The one-level ladder of dome head and cylindrical shell inner core assembly welding has the technological scheme that prolongs straight flange, increases the straight flange structure through the one-level ladder at dome head and cylindrical shell inner core assembly welding, for compatibility of deformation provides changeover portion; Make the whole locus of discontinuity of container depart from welded joint; Simultaneously, make the revolution bus of the welding seam bias dome head of dome head and inner core, convert the dome head and the assembly welding of inner core to two straight tubes and dock assembly welding; Therefore formed welded joint also converts the category-B welded joint into by the category-A welded joint that common no straight flange dome head and inner core welding form; According to the relevant regulations requirement among the GB150, need not to do postweld heat treatment behind the dome head of the integral multi-layered binding vessel of high pressure of the utility model and the inner core assembly welding, not only simplified production technology; And reduced cost of production, shortened the manufacture cycle; Owing to reasonably define the height that prolongs straight flange; Reduced to prolong the influence of straight flange, made bearing capacity and the integral multi-layered binding vessel index of high pressure that Security all reaches or be superior to the general spherical shape end socket of the integral multi-layered binding vessel of high pressure of the utility model the dome head pressure-bearing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is integral multi-layered binding vessel dome head of the high pressure of the utility model and cylindrical shell weld part structural representation.
Embodiment
As shown in Figure 1; The integral multi-layered binding vessel of the utility model high pressure comprises dome head 1, cylindrical shell 2, and cylindrical shell is made up of inner core 5 and wrapping laminate 4; The end of dome head and cylindrical shell welding is a stepped shaft, and the one-level ladder of dome head and cylindrical shell inner core assembly welding has the straight flange 3 of prolongation.
When end socket nominal diameter DN≤2000mm, the height h that prolongs straight flange is 20mm; When end socket nominal diameter DN>=2000mm, the height h that prolongs straight flange is 40mm.
Claims (2)
1. integral multi-layered binding vessel of high pressure; Comprise dome head, cylindrical shell; Cylindrical shell is made up of inner core and wrapping laminate, it is characterized in that: the end of dome head and cylindrical shell welding is a stepped shaft, and the one-level ladder of dome head and cylindrical shell inner core assembly welding has the prolongation straight flange.
2. the integral multi-layered binding vessel of high pressure according to claim 1 is characterized in that: the height that prolongs straight flange is 20-40mm.
