Abstract
The utility model discloses a structure for connecting an internal container and an external container of a low-temperature liquid storage tank. The structure comprises the inner container, the outer container, and an overhead multi-way assembly on the outer container, wherein the inner container is located in the outer container, and is provided with an upper head. The structure is characterized by further comprising an expansion joint neck tube, wherein one end of the expansion joint neck tube is connected with the overhead multi-way assembly, and the other end of the expansion joint neck tube is connected with the upper head of the inner container. According to the structure, the static evaporation rate of media of the low-temperature liquid storage tank can be effectively reduced, and the enough axial flexibility is provided for the inner container.
Description
Technical field
The utility model relates to a kind of interior outer container linkage structure of cryogenic liquid tank.
Background technique
At present, cryogenic liquid tank adopt connecting tube connect in during outer container, be limited to mezzanine space, the length of connecting tube can not be long, the relative evaporation of tank body is higher, more difficultly reaches the requirement of the adiabatic deep cooling pressurized container of GB/T18442-2011 < < fixation type vacuum > > to relative evaporation.Meanwhile, independent connecting tube connection easily causes outer upper cover to deform.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of interior outer container linkage structure of cryogenic liquid tank is provided, and it can effectively reduce the medium static evaporation rate of the cryogenic tank that is easy to get soon, gives axially enough extending amounts of inner container.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of interior outer container linkage structure of cryogenic liquid tank, comprise inner container, outer container and be arranged on many logical assemblies on the top on outer container, inner container is positioned at outer container, inner container has upper cover, it is characterized in that: also comprise expansion joint neck tube, one end of expansion joint neck tube is connected with the upper many logical assemblies in top, and the other end of expansion joint neck tube is connected with the upper cover of inner container.
Further in order to fix the axial direction of inner container, avoid expansion joint neck tube to be subject to the tensile buckling of inner container gravity and the distortion of outer container upper cover, between described inner container and outer container, be provided with axially support assembly, this axially support assembly comprises suspender belt backing plate and suspender belt, suspender belt backing plate is arranged on the madial wall of outer container, one end of suspender belt is connected on suspender belt backing plate, and the other end is connected with the bottom of inner container.
Further in order to fix the radial direction of inner container, avoid expansion joint neck tube to be subject to the tensile buckling of inner container gravity and the distortion of outer container upper cover, between described inner container and outer container, be provided with radial support assembly, this radial support assembly comprises support stick and supporting sleeve, support stick is fixedly connected on inner container and along the radial arrangement of inner container, described supporting sleeve is fixedly connected on outer container, and described support stick is inserted in supporting sleeve.
Adopted after technique scheme, adopt expansion joint neck tube to replace connecting tube, can effectively reduce the medium static evaporation rate of cryogenic liquid tank, adopt axially support assembly and radial support assembly can fix interior outer container, avoided original inner container gravity by connecting tube, to directly act on the local phenomenon that causes the distortion of outer container upper cover of upper cover of outer container.
Accompanying drawing explanation
