Abstract
The utility model discloses a jacketed container inner barrel body welding structure. The jacketed container inner barrel body welding structure comprises an inner barrel body and a jacket, wherein the jacket is welded and is subjected to transition on the inner barrel body by a base plate; an air hole is formed in the base plate; the thickness of the base plate and the thickness of the inner barrel body are equal. According to the jacketed container inner barrel body welding structure, the base plate is adopted for transition, the thickness of the base plate and the thickness of the inner barrel body are generally equal, and compared with an annular plate, the thickness of the base plate is greatly thinned, and the cost is controlled.
Description
Technical field
The utility model relates to a kind of inner barrel, relates in particular to a kind of jacketed vessel inner barrel Welding Structure.
Background technology
For pressure vessel, under given conditions, post weld heat treatment is an indispensable operation, and its Main Function is to eliminate welding stress, improves the moulding and toughness of welding point, avoids cracking etc.The carrying out of post weld heat treatment plays vital effect to coming into operation of follow-up equipment.
Need to carry out the jacketed vessel of post weld heat treatment for inner core, conventionally have following two kinds of processing modes.
Shown in Fig. 1, adopt the normal structure of being used to have, chuck 3
,be directly welded in inner core 1
,upper, make inner core 1
,heat treatment cannot carry out separately, must be by chuck 3
,with inner core 1
,after welding, carry out in the lump, so on the one hand due to chuck 3
,there is the effect of thermal insulation layer, may cause the inequality of being heated of inner core, and after heat treatment, need inner core 1
,carry out the water pressure test, to verify inner core 1 after heat treatment
,bearing capacity.Due to inner core 1 now
,with chuck 3
,weld, when the water pressure test, inner core 1
,whether have leak source, we cannot observe out from outward appearance, so chuck 3
,welding can only be at inner core 1
,separately heat treatment----hydraulic pressure complete and qualified after carry out.
Shown in Fig. 2, another kind of normal structure, though can meet above-mentioned requirements in technique, ring flat-plate 2
,thickness thicker after as calculated, cause the rising of cost.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
For addressing the above problem, the utility model provides a kind of jacketed vessel inner barrel Welding Structure.
The technical solution adopted in the utility model is:
Jacketed vessel inner barrel Welding Structure, comprises inner barrel and chuck, and described chuck on inner barrel, has air-vent on described backing plate, the thickness of described backing plate and inner core body wall uniform thickness by backing plate welding transition.
The beneficial effects of the utility model: adopt backing plate transition, the thickness of backing plate is generally all got and inner barrel uniform thickness, the ring flat-plate of comparing, attenuate is more, has controlled cost.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of another kind of prior art.
Fig. 3 is structural representation of the present utility model.
Wherein: 1, inner barrel, 2, backing plate, 3, chuck, 4, air-vent.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As shown in Figure 1, jacketed vessel inner barrel Welding Structure of the present utility model, comprises inner barrel 1 and chuck 3, and chuck 3 on inner barrel 1, has air-vent 4, the thickness of backing plate 2 and inner barrel 1 wall uniform thickness by backing plate 2 welding transition on backing plate 2.
Chuck 3 on inner barrel 1, can carry out separately the heat treatment of inner core 1 by backing plate 2 welding transition, can not cause inner barrel 1 inequality of being heated.
On backing plate 2, have air-vent 4, can check out that by this air-vent 4 backing plate 2 is covered weld seam by chuck chamber and has or not leakage phenomenon, send in advance alerting.
Adopt backing plate 2 transition, the thickness of backing plate 2 is generally all got and inner barrel 1 uniform thickness, the ring flat-plate of comparing, and attenuate is more, has controlled cost.
Claims (1)
1. jacketed vessel inner barrel Welding Structure, comprises inner barrel and chuck, it is characterized in that: described chuck on inner barrel, has air-vent on described backing plate, the thickness of described backing plate and inner core body wall uniform thickness by backing plate welding transition.
