Abstract
The invention discloses a sleeve structure of an outer container of a low-temperature pressure vessel. The sleeve structure comprises an inner container and the outer container. The outer container is sleeved on the inner container. The outer container comprises an outer left head, an outer right head and an outer cylindrical body. Multiple supports are arranged between the inner container and the outer container. The supports are fixedly welded to the outer cylindrical body by support caps. The outer left head and the outer right head are sealedly welded respectively to two ends of the outer cylindrical body. The sleeve structure has the advantage that a composite welding line is arranged at a left side of the outer left head and the outer cylindrical body so that the multiple supports and the support caps can be welded simultaneously, gaps between the supports and the inner and outer containers can be adjusted conveniently, the supports are distributed uniformly, and the outer left head, the outer right head and the outer cylindrical body are orderly welded, and thus the problem that the existing welding technology adopts a support step-by-step welding process is solved and welding stress at the welding line is reduced and cracking of the support parts of the pressure vessel is avoided in use.
Description
Technical field
The present invention relates to a kind of sleeve structure of low-temperature pressure container outer container, belong to the low-temperature pressure container technical field.
Background technique
Outer double-layer structure in the general employing of portable low-temperature pressure container; as shown in Figure 1; this double layer construction passes through up and down totally 8 supports and forms; each support is placed in the support cap; support cap and outer container are welded to connect; outer container comprises outer left end socket; outer left-hand cylinder body; outer right end socket; four parts of outer right cylindrical shell; the bevel for welding of last composite weld is opened the right of left-hand cylinder body and the left side of outer right cylindrical shell outside respectively; for guaranteeing the circularity of cylindrical shell; adopt the vertical sleeve structure of horizontal vessel; before inner container and the outer container suit; earlier respectively outer left end socket and outer left-hand cylinder body; outer right end socket and outer right cylindrical shell weld; during suit earlier outer right cylindrical shell with outer right end socket is vertical is placed on the machine frame; then inner container is lifted by crane and outer right cylindrical shell suit with driving; after cover installs; in support is placed in; between the outer container; weld support cap then; after 4 supporting structures weld; lift by crane outer left-hand cylinder body and outer left end socket; compound with outer right cylindrical shell; after other 4 supports and support cap assembling are finished; with outer left-hand cylinder body and the last composite weld of outer right cylindrical shell; 8 are supported suit at twice; cause support distribution inhomogeneous; the weld joint welding stress of support cap is bigger, in use the cracking problem occurs through regular meeting.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of minimizing weld joint welding stress, made the sleeve structure of the low-temperature pressure container outer container that container support place in use no longer ftractures.
Technical solution of the present invention is achieved in that a kind of sleeve structure of low-temperature pressure container outer container, comprises inner container, outer container, and described inner container is sleeved in the outer container, and described outer container comprises outer left end socket, outer right end socket, outer cylinder body three parts; Be provided with a plurality of supports between described inner container and the outer container; Described each support is fixedly welded on the outer cylinder body by support cap, and seal welding is at the outer cylinder body two ends respectively for described outer left end socket, outer right end socket, and the composite weld on the described outer container is arranged on the left side of outer left end socket and outer cylinder body.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The sleeve structure of a kind of low-temperature pressure container outer container of the present invention, by composite weld being arranged on the left side of outer left end socket and outer cylinder body, a plurality of supports and support cap can be welded simultaneously, the convenient gap of supporting with inside and outside container of adjusting, make to support evenly and distribute, outer left end socket, outer right end socket, outer cylinder body three parts are successively welded, solve the problem that supports the substep welding in the prior art in the welding process, reduced the welding stress of weld joint, made container support place in use the cracking problem no longer occur.
