Definitions

  • the invention relates to a closed expansion vessel for liquid-filled systems according to the preamble of claim 1.
  • Expansion vessels of this type are mainly used to compensate for volume changes in the liquid occurring in drinking water and heating systems or to maintain a minimum pressure in the system.
  • the expansion vessel has a flexible membrane which separates its interior into a liquid space, which is connected to the system in question, and an air or gas space, in which a certain form is generally present.
  • the air or gas cushion is compressed, and the associated increase in pressure ensures that the liquid taken up is returned to the system in the event of a drop in pressure or a decrease in volume.
  • Separation membranes are used in a wide variety of designs and installation methods. Examples include the so-called inverted membranes, which are installed as the actual partition in the expansion tank, and the bladder membranes, which form a flexible hollow body within the expansion tank.
  • a container which is visible from the outside is arranged on the outside of the expansion vessel, the interior of which is connected to the gas space via a passage.
  • the gas space is provided with an extension that can be seen from the outside. If the separating membrane should now leak, then the liquid, if it penetrates into the gas space, will also run into the container and can be immediately recognized from the outside. With a simple visual inspection, it can thus be determined at any time whether the separating membrane is still intact or possibly has a defect.
  • the passage is preferably provided in the lower third of the gas space, particularly preferably at its lowest point.
  • a float can be contained in the interior of the container, the exterior of which expediently has a clearly visible rontrast color.
  • the solution according to the invention enables any penetration of liquid into the gas space from the outside to be determined in a simple and safe manner.
  • the associated additional costs in the production of expansion vessels are very low, which is of crucial importance in view of the fact that such vessels are nowadays offered at very low prices.
  • the invention only requires a single additional opening in the vessel wall, the diameter of which can also be kept comparatively small.
  • points that entail the risk of increased pressure loss should be avoided as far as possible, and experience has shown that such points are more effectively sealed the shorter and simpler their circumferential line is.
  • conceivable measuring devices with electrodes arranged in the gas space are disadvantageous, since for this purpose conductor leadthroughs have to be inserted in the vessel wall, which can only be sealed satisfactorily with considerable effort because of the necessary insulation.
  • the expansion vessel generally designated 2 in FIGS. 1 and 2, has a vessel wall 4, which is generally made of steel. This encloses a gas space 6. In the gas space 6 a bubble separating membrane 8 is mounted, the interior of which forms a liquid space 10.
  • the liquid chamber 10 is connected to a via a connection 12 - Not shown here - connected liquid-filled system.
  • a container Arranged on the lower wall section 4.1 of the expansion vessel 2 is a container, designated in its entirety by 14, the construction of which is described in more detail below.
  • the interior of the container 14 can be seen from the outside and is connected to the gas space 6 of the expansion vessel via a passage 16.
  • FIG. 2 it is indicated in an illustrative manner how liquid 18 penetrates from a possibly leaky point 20 of the separating membrane 8 into the gas space 6 and subsequently runs through the passage 16 into the container 14 and can be determined there.
  • the container 14 is formed by a tube 22 which is closed on one side and which is pushed with its open side onto a connection fitting 24 in a press fit.
  • the tube is transparent and preferably made of plastic and conveniently has a diameter of about 0.5 to 2 centimeters.
  • the fit of the tube on the fitting and their mutual sealing can optionally be secured with a suitable adhesive.
  • connection fitting 24 is screwed into the lower vessel wall section 4.1, an interposed sealing ring 26 additionally sealing the connection point.
  • the connection fitting could also be attached to the Weld on the wall or form one piece with the wall.
  • the longitudinal axis of the container 14 expediently runs vertically. However, it could just as well be oriented obliquely to the vertical, a certain inclination to the horizontal, preferably by an angle of at least 30 degrees, being maintained in order to allow the ingress of liquid or the escape of the gas present in the container in the event of a membrane defect .
  • a float 28 in the interior of the tube 22, which in the present case has the shape of a ball.
  • the float 28 lies on the bottom of the tube (position drawn in solid lines).
  • the float 28 is raised in the direction of arrow A (position shown in dashed lines) and thus indicates a defect in the separating membrane, which is clearly recognizable from the outside.
  • the possible displacement distance of the float 28 is preferably limited so that it can be seen from the outside in any case.
  • the lower edge 30 of the connection fitting 24 forms an upper stop for the float 28, since the float diameter is chosen to be larger than the inside diameter of the connection fitting.
  • any other limiting means could also be considered for this purpose, such as additionally inserted stop elements or a corresponding narrowing of the container cross section.
  • the container that is visible from the outside does not necessarily have to be tubular, but could also be spherical or cuboid, for example, or have any other suitable shape. It would also be sufficient if the container were only partially visible.
