  • a heat insulating material having a substantial resistance to compression
  • an inner tank 3 is provided inside of this heat insulating layer 2.
  • This inner tank 3 is constructed by a thin film construction made of a low-temperature resistant material such as aluminum, nickel steel etc.
  • the inner tank 3 has a sufficient flexibility and is constructed such that when it is subjected to the inner pressure it could not withstand such inner pressure and hence is deflected towards and brought into close contact with the heat-insulating layer 2, thereby transmitting the inner pressure to the latter. Therefore, substantially all of the inner pressure is supported by the rigid outer tank 1 having the pressuretight construction.
  • the inner tank 3 consists of a flat bottom plate 6 and a cylindrical side shell connected through a thin film connector construction 5 in the shape of a portion of a toroid to the bottom plate 6.
  • the cylindrical side shell plate is provided with vertically extending corrugations 4 which permits the cylindrical side shell plate to expand and contract in' the peripheral direction thereof.
  • l0 designates a top cover for the inner tank, which is constructed by a thin plate made of Al, Ni-steel etc. and whose outer peripheral edge in opposition with the inner tank 3 is bent downwards to form a small gap therebetween.

  • 12 designates a member made of wood etc. and adapted to support the top cover 10 of the inner tank 3 an connect the top cover 10 to the truss 8.
  • FIGS. 68 Various types of the devices for suspending the upper peripheral edge of the inner tank 3 may be constructed and embodiments thereof will now be explained with reference to FIGS. 68.
  • the upper peripheral edge 13 of the inner tank 3 is pivoted to one end of a rocking lever l4 arranged on the top cover 10 and pivoted to it.
  • the rocking lever 14 is provided at its opposite end with a weight 15 which is always in balance with that end which suspends the upper peripheral edge 13 of the inner tank 3.
  • the upper peripheral edge 13 of the inner tank 3 is'suspended through a spring or bellows 16 from the top cover construction 7 of th outer tank 1.
  • the upper peripheral edge 13 of the inner tank 3 is suspended through a wire and a pulley 17 from the top cover construction 7 of the outer tank 1 and always in balance with a weight 18 acting upon the pulley 17. All of these embodiments provide means for freely following the load produced by the low-temperature liquefied gas charged in the inner tank 3 and hence follow the displacement of the upper peripheral edge 13 of the inner tank 3.
  • the inner tank 3 is made of the thin film renders it possible to bring the inner tank 3 into a close contact with the heat-insulating layer 3 by means of the inner pressure produced by the low-temperature liquefied gas charged in the inner tank 3 thus transmitting the inner pressure to the heatinsulating layer 2, with the result that the outer tank 1 can withstand the above-mentioned inner pressure and hence can store the low-temperature liquefied gas in a safe manner.
  • FIG. 3 diagrammatically illustrates the contraction of the inner tank 3 shown in vertical cross section. As seen from FIG. 3 the inner tank 3 takes a sectional form shown by a full line ac at room temperature under no load condition.
  • the bottom plate 6 when exposed at the low temperature under the no load condition is contracted towards its center to displace a point cto a point c.
  • the contraction of the side shell reduces the diameter of the inner tank 3 and hence displaces a point a to a point a, with the result that a full line ac is displaced to dotted lines ac.
  • the liquid load applied to the inner tank 3 having the thin film structure tends to the inner tank 3 to deflect and bring it into a close contact with the heatinsulating layer 2, thereby tending to displace the dotted lines a'-c to the original full line ac.
  • the contraction of the bottom plate 6 from the point c to the point c and the contraction of the side shell plate 3 from the point a to the point a tend to bring back the point a to the point b instead of bringing back the point a' to the point b instead of bringing back the point a to the point a.
  • the deflection of the inner tank 3 caused by the liquid load at the low temperature consists of a longitudinal contractive displacement represented by the movement of the point a to the point b, a peripheral expansion of the side shell 3 from the dotted lines a-c under no load condition to the full line bc under loaded condition, and a change of curvature of the connector construction 5.
  • the longitudinal contractive displacement can freely be carried out with the aid of the balancing weight device 9 suspending the upper peripheral edge 13 of the inner tank 3, while the peripheral expansion of the side shell plate can be carried out by deformation of the longitudinal corrugations 4.
  • deformation of the corrugations 4 is illustrated in FIG. 4-A in which a full line shows the state of the shell 3 in section at room temperature under no load condition and dotted lines show how the side shell 3 deforms at the low temperature under load condition.
  • the corrugations 4 become expanded by the presence of the inner pressure.
  • FIG. 4-A points d, e and f are displaced to points d, e and 1", respectively, and the distance between the points e and f is reduced by contraction to that between the points e and f.
  • the deformation of the corrugations 4 causes the distance between the points d and e to increase to that between the points d and e.
  • the elongation between the points d and e compensates for the contraction between the points 2 and f thus bringing the side shell plate 3 into contact with the heat insulating wall 2.
  • the corrugations 4 are liable to be easily deformed by an extremely small force so that dangerous. thermal stress is not produced in the side shell 3.
  • FIG. 4-8 shows a variant of the corrugations 4 shown in FIG.
  • corrugations 4 in which corrugations 4 are different in shape from the corrugations 4 shown in FIG. 4-A.
  • the corrugations 4 constitute a camber of a plate. This camber is eliminated by contraction of the side shell 3 at the low temperature to deform the side shell 3 into a circular form without undulations in section, thereby bringing it into a close contact with the inside surface of the heat-insulating layer 2.
  • the corrugations herein described also means the above mentioned camber.
  • the inner tank 3 is constructed by a thin film and the corrugations terminate smoothly at the neighborhood of the connector construction 5 so that the curvature of the connector construction 5 can be changed without difficulty.
  • Such change of the curvature of the connector construction 5 may more easily be carried out by provision of additional corrugations (not shown) along the periphery of the connector construction 5.
  • the inner tank according to the invention can be easily deformed in response to the load and the contraction phenomenon due to the low temperature and thereby reduces crack and damages of the tank and stores the low-temperature liquefied gases in a safe manner.
  • the downwards bent peripheral edge of the top cover 10 of the inner tank 3 prevents the low-temperature liquefied gas from flowing out of the inner tank 3 even when the level of the lowtemperature liquefied gas abruptly changes owing to earthquake or other causes.
  • the small gap formed between the downwards bent peripheral edge of the top cover 10 and the upper peripheral edge 13 of the inner tank 3 serves to allow communication between inside and outside of the inner tank 3 and hence passage of vapor.
  • the space formed between the inner and outer tanks is filled with vapor so that frost and ice etc. do not occur at those portions which are positioned in this space without necessitating any means of drying the space formed between the inner and outer tanks, as in double-walled tanks heretofore proposed.
  • the storage tanks according to the invention are simple and economical to construct, and result in a considerable safety in the storage of the low-temperature liquefied gases.
  • a liquefied gas storage tank comprising, in combination, an outer tank having a pressure tight and hermetically sealed rigid construction, a heat-insulating layer having a substantial resistance to compression and provided at the inside surface of at least side and bottom portions of said outer tank, a top closure structure provided on said outer tank, an inner tank having a thin wall construction located inwardly of said heat insulating layer and adapted to contain a low-temperature liquefied gas therein, the pressure of said liquefied gas being supported through said inner tank and heat insulating layer by said outer tank, said inner tank being formed into a bagshaped body consisting of a flat bottom plate and a cylindrical side shell connected at its bottom edge to said flat bottom plate by a thin film connector construction in the shape of a portion of a toroid.
  • Said side shell including an upper, peripheral edge defining an upper opening, movable suspension means connecting said upper peripheral edge of said bagshaped inner tank to said top closure structure of said outer tank, said upper opening of said inner tank being covered by a top cover plate secured to said top closure structure independently of said inner tank and provided with a heat-insulating layer, and said inner tank having elongated substantially vertical corrugations arranged in spaced relationship about the periphery of said side shell, said corrugations extending radially across said connector construction and smoothly reducing in width as they approach said flat bottom plate and smoothly terminating in the area of the junction of said connector constructions to said flat bottom plate.
