Definitions

  • the invention relates to a double jacket storage for the preparation and storage of hot service water, consisting of a container provided with cold water supply and hot water outlet connection, which is surrounded by a shape-matching outer jacket guiding the heating medium, on which heating medium supply and return connections are arranged.
  • Such double jacket storage are well known and in use, so that no special printed evidence is required in this regard.
  • the actual storage container sits in the form-fitting, pot-shaped outer jacket and protrudes with one end, i.e. with its bottom located out of the outer jacket, or the then only cylindrical outer jacket essentially comprises only the cylindrical part of the container.
  • an end ring bent off on the outer circumference is generally welded in, which must therefore be manufactured separately and requires two circumferential weld seams for its connection to the container and the connecting edge of the outer casing.
  • a so far better solution is a storage container according to DE-U-91 13 120, in which the end ring is designed in the form of an offset of the peripheral edge of the container bottom, to which the end edges of the side wall parts of the inner and outer containers are connected in a liquid-tight manner.
  • This requires a corresponding dimensioning allowance on the floor panel cut so that the end ring area can also be formed when the floor is being shaped.
  • special shaping measures are required to ensure a coaxial assignment from the bottom to the cylindrical part of the container and from the end edge of the outer casing to the end ring molded onto the bottom.
  • the invention has for its object to improve and simplify a double jacket storage of the generic type with respect to its outer jacket termination in that it is neither the manufacture and welding of a separate ring still requires a special shape of the container bottom.
  • the circumferential corrugation which is curved outwards, can be produced in a simple manner, possibly even when the sheet metal blank is rolled into the cylindrical part of the container, the end edge of the outer jacket then simply being attached to the circumferential corrugation and welded.
  • the peripheral bead is advantageously provided with a diverging contact and centering surface towards the adjacent bottom of the container, to which the correspondingly diverging end edge of the outer jacket is applied and welded.
  • the diverging end edge of the outer casing can be designed as an extension of a circulating cranking oriented towards the relevant floor, which will be explained in more detail below.
  • the outer casing at the other end with a locking edge that is crimped against the container, this with an axis parallel to the container axis, towards the adjacent floor Provide directed investment edge and is welded to the container with this. It would also be conceivable and feasible to provide the principle of arranging a peripheral bead at this end, although this peripheral bead must be dimensioned somewhat less in terms of its bulge around the end edge of the outer jacket, which determines the connection to the other peripheral bead is to be able to slide over the less convex bead.
  • the double jacket storage consists of a cold water supply and hot water outlet connection 3, 4 provided container 1, which is surrounded by a shape-matching, the heating medium leading outer jacket 2, are arranged on the heating medium supply and return connections 6, 7.
  • FIG. 1 shows a vertical store, the outer casing 2 being cup-shaped and enclosing the container 1 except for the upper part, and in FIG. 4 a horizontal store in which only the essentially cylindrical part 1 'of the container 1 from the outer casing 2 'is included.
  • FIG. 3 The embodiment according to FIG. 3 is preferred, in which the peripheral bead 9 is provided with a diverging contact and centering surface 12 towards the adjacent bottom 11 of the container 1 and the correspondingly diverging end edge 10 of the outer jacket 2 is applied and welded thereon.
  • the outer casing 2 automatically receives an axially parallel centering to the container 1 when it is joined together.
  • the diverging end edge 10 of the outer casing 2 is also designed as an extension of a circumferential crank 13 oriented converging towards the relevant floor 11.
  • a circumferential crank 13 is extremely simple to produce and in connection with the diverging end edge 10
  • this embodiment has the advantage that the circumferential bead 9 does not have to be bulged out so deeply.
  • the outer casing 2 ' which here only comprises the cylindrical part 1' of the container 1, is connected in the same way as explained in connection with FIG. 3 to the container 1 or to its peripheral bead 9 on the left side .
  • the outer casing 2' (see FIG. 5) is provided with a locking edge 14 which is cranked towards the container 1 and which has an abutment edge which extends axially parallel to the container axis 15 and is directed towards the adjacent bottom 11 ' 15 and is welded to the container 1.
  • this termination area could also be formed in the same way as shown in FIG. 3, but with the proviso that the peripheral bead 9 there only may be bulged out so far that the end edge 10 can be pushed over it.
  • the sealing edge 14 can then be dimensioned to be less wide, and the contact edge 16 is then also adapted in its orientation to the contact and centering surface there of the peripheral bead.
