Definitions

  • the invention relates to an expansion tank for accommodating a storage volume at pump operated freshwater V ersogungsanlagen or for receiving temperature related volume changes in an enclosed fluid system, in particular a heating system with hot water supply, with a fixed housing and between two liquid terminals thereof arranged stretchable, liquid-filled member.
  • the stretchable member In a known expansion vessel of this type (DE-GM 82 03 569), the stretchable member consists of a bag-shaped membrane, within which a piece of pipe serving as a discharge line is arranged, at least one overflow channel being formed between this piece of pipe and the interior of the bag-shaped membrane. Because of this design, a certain flow through the vessel always takes place during the drawing off of a quantity of liquid, which counteracts undesirable bacterial formation, particularly in fresh water supply systems.
  • the object of the invention is to provide a solution which completely excludes the formation of bacteria due to the contact of partial areas of the stretchable member with one another or with internal internals.
  • this object is achieved according to the invention in that the stretchable member in the unpressurized initial state is designed as a dimensionally stable rubber cylinder, within which there is only liquid, and in that the interior between the fixed housing and the rubber Cylinder is constantly connected to the atmosphere.
  • the fixed outer housing assumes the function of the inner plastic tube provided in the known construction for the axial determination of the connections on both sides and also serves to provide a sufficiently secure shielding in accordance with the legal provisions for pressure vessels.
  • the fixed housing is formed from a plurality of sheet metal parts which are connected to one another by means of spot welding such that the locations of the spots which remain open between the spot welds Welds connecting the inner space with the A t-phere form.
  • the expansion tank shown in the drawing has a fixed housing 1, which is composed of two end sheet metal half-shells 2 and a cylindrical sheet metal section 3 arranged between them, the individual parts being connected to one another by welding.
  • connection flanges 4 are welded, in which a strong rubber cylinder 5 is fastened by means of fastening connection flanges 6, which are provided with connection nipples 7 for liquid supply and discharge lines, not shown.
  • a vent opening 8 is formed in each end shell part 2, such. that the interior 9 between the fixed housing 1 and the rubber cylinder 5 is depressurized or connected to the atmosphere.
  • connections shown in the drawing as continuous weld seams 10 between the half-shell-shaped sheet metal parts 2 and the cylindrical middle part 3 can also be designed as spot weld seams, such that the points of the weld that remain open between the spot welds stitched the connection of the interior 9 with the atmosphere.
  • the rubber cylinder can also consist of other rubber-like materials, that is to say of materials that can be deformed in a joint-free manner, to which all elastomers belong.
  • the dimensioning is always carried out according to the liquid pressures that occur.
  • the rubber cylinder could also be equipped with spring-elastic reinforcements, e.g. B. spiral springs, metal alternativebälgen F o. The like., May be provided.
  • Essential Lich is a dimensioning and design such that the cylinder shape is reset and maintained in any case in the unpressurized initial state, so that contact with inner surface areas is excluded with certainty.
