Abstract
The utility model discloses a reinforced type safety injection tank spherical crown. The reinforced type safety injection tank spherical crown comprises a circular-arc-shaped spherical crown body, wherein the spherical crown body is formed by welding a plurality of split steel plates, wherein the opening end of the spherical crown body is outwards expanded to form a blank holder body; an upper anti-deformation ring is arranged on the blank holder body; an outer anti-deformation ring is arranged outside the spherical crown body below the upper anti-deformation ring; the outer anti-deformation ring wraps the outer wall of the spherical crown body; and a rib plate is arranged between the outer anti-deformation ring at the outer part of the spherical crown body and the blank holder ring. The reinforced type safety injection tank spherical crown has the advantages that the anti-deformation capacity of the spherical crown body is improved by virtue of the upper anti-deformation ring and the outer anti-deformation ring on the spherical crown body; and the rib plate is welded between the outer anti-deformation ring and the blank holder body, so that the outer anti-deformation ring can be well fixed on the spherical crown body.
Description
Technical field
The utility model relates to a kind of reinforced peace and annotates the case spherical crown.
Background technology
It is fully cooling for reactor core is carried out that peace is annotated case, it is an important component part of security system, it is spherical that peace is annotated case, its structured material is carbon steel, the inside surface of install bin is one deck stainless steel material, and the basic structure that peace is annotated case mainly comprises spherical crown, middle stack shell and lower spherical crown, and the structural strength of spherical crown in the past reduces, after between using one section, spherical crown is prone to the phenomenon of distortion, affects the serviceable life of spherical crown.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of reinforced peace to annotate the case spherical crown, solve low, the yielding defect of spherical crown intensity in the past.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of reinforced peace is annotated the case spherical crown, comprise the spherical crown body that is circular-arc, the spherical crown body is formed by the Plate Welding of multi-disc limb shape and the spherical crown body open end launches to form the flanging circle body laterally, the anti-deformation ring is set on the flanging circle body, the spherical crown body that is positioned at anti-deformation ring below is outside equipped with outer anti-deformation ring, outer anti-deformation ring is wrapped on the outer wall of spherical crown body, between described outer anti-deformation ring in the spherical crown body exterior and flanging circle body, is provided with gusset.
Further, gusset is welded between outer anti-deformation ring and flanging circle body.
The beneficial effects of the utility model are: provide a kind of reinforced peace to annotate the case spherical crown, by anti-deformation ring and outer anti-deformation ring are set on the spherical crown body, improve the non-deformability of spherical crown body, and between outer anti-deformation ring and flanging circle body, the upper gusset of welding, make outer anti-deformation ring can better be fixed on the spherical crown body.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation that peace is annotated the case spherical crown;
Wherein: 1, spherical crown body, 2, the flanging circle body, 3, outer anti-deformation ring, 4, gusset.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, a kind of reinforced peace is annotated the case spherical crown, comprise the spherical crown body 1 that is circular-arc, spherical crown body 1 is formed by the Plate Welding of multi-disc limb shape and spherical crown body 1 openend launches to form flanging circle body 2 laterally, be welded with the anti-deformation ring on flanging circle body 2, spherical crown body 1 outside weld that is positioned at anti-deformation ring below is connected to outer anti-deformation ring 3, outer anti-deformation ring 3 is wrapped on the outer wall of spherical crown body 1, be provided with gusset 4 between described outer anti-deformation ring 3 in spherical crown body 1 outside and flanging circle body 2, gusset 4 is welded between outer anti-deformation ring 3 and flanging circle body 2, external diameter≤the 4850mm of outer anti-deformation ring 3.
By anti-deformation ring and outer anti-deformation ring 3 raising spherical crown body 1 non-deformabilities are set at spherical crown body 1, and the upper gusset 4 of welding between outer anti-deformation ring 3 and flanging circle body 2, make outer anti-deformation ring 3 can better be fixed on spherical crown body 1.
