APPARATUS FOR STORING AND FEEDING CRYOGENIC PRODUCTS Russian patent published in 2000 - IPC

FIELD: pipeline systems for feeding cryogenic products. SUBSTANCE: apparatus includes heat insulated inner envelope, outer envelope, drain and loading pipelines, safety and locking fittings. In inner envelope of tank there is intake made of odd number of horizontal pipelines, at least of three pipelines, arranged in central vertical plane passing through lengthwise horizontal symmetry axis of tank. Cavity of central pipeline is joined by means of elbows with cavities of upper and lower pipelines having at opposite sides open tapered ends whose lower edges rest upon faces of plumbs freely suspended on axles secured to inner envelope of tank in planes normal relative to pipelines of intake. Drain pipeline is joined with central pipeline of intake in such a way that symmetry axis of drain pipeline coincides with symmetry axis of tank. EFFECT: possibility for preventing penetration of liquid phase of cryogenic products into cavity of drain pipeline at storing cryogenic product in tank with open draining unit at lengthwise and crosswise liquid oscillations, reduced loss of cryogenic product. 3 dwg
