- Such a container is fitted to the respective tubular manifold can be connected.
- the production is particularly easy because the bubble-shaped Membrane in a simple way with its opening edge, preferably sealing, either in the water connection or be inserted into the gas connection can, whereupon then the container in question detachable at the assigned distributor or the assigned Distribution line is attached, for example by means of a screw connection. This ensures that one Damage to the membrane due to thermal stress, as is the case for example with a welding process would be avoided reliably.
- a particularly preferred embodiment is provided that is the opening edge of the bubble-shaped membrane opposite end of the membrane attached to a holding element is.
- the holding element can be formed either in the container his or in the distributor or the connection line.
- the membrane preferably has a free end on one side Rastansatz on, in a corresponding recess can engage in the retaining element.
- the respective other connecting piece in which the opening edge the membrane is not inserted, firmly with the Connecting line or the distributor is connected.
- the respective other connecting piece offers in particular a welded joint, which manufacturing technology a particularly low cost means.
- the respectively detachable with the distributor or the connecting line connected connecting pieces, in which the Opening edge of the membrane is used preferably a screw connection.
- a Plug connection for example a bayonet connection, be provided.
- the preferred bottle-shaped container consist preferably made of metal or plastic.
- metal in particular aluminum is suitable.
- bottle-shaped containers are made of plastic, is preferably provided that they each off a body made in a molding process with one-piece molded water and gas connection piece consist.
- An expansion vessel for heaters or the like, in particular for wall-mounted baths, is generally designated 1.
- This Expansion vessel 1 in the embodiment 1, a tubular distributor 2 with three connecting pieces 3 on.
- This tubular distributor 2 is connected to a not shown water mains.
- all connecting pieces 3 of the distributor 2 are preferably bottle-shaped container 4 detachably arranged, screwed in particular, as indicated by nuts 5 is. All three bottle-shaped container 4 are identical.
- Each bottle-shaped container 4 has an approximately cylindrical Cavity, which of a bubble or ball-shaped membrane 8 in a water chamber 6 and a Gas space 7 is divided.
- the membrane 8 is with its opening edge 8a sealing in a water connection 9 inserted and open to the connection piece 9, i.e. the respective bubble-shaped membrane 8 is via the connecting pieces 3 and 9 and the tubular Distributor 2 directly to the water supply network to be connected the heating system in connection.
- the inner the respective bubble-shaped membrane 8 thus forms respectively the water space 6. It can be seen all the water spaces 6 of the bottle-shaped container 4 via the tubular Distributor 2 connected to each other, leaving a Ensures pressure equalization between the water chambers 6 is.
- the bottle-shaped container 4 also have top side smaller gas connection piece 10, which with connection piece 11 connected to a connecting line 12 are.
- This connection line 12 is at a suitable location provided with a gas filling valve 13.
- the gas chambers 7 of the individual bottle-shaped container. 4 via the connecting line 12 for pressure equalization with each other can have a single Gas filling valve 13 with the required gas, for example Nitrogen, to be filled.
- the expansion vessel 1 is formed like a module, it consists in principle of the tubular distributor 2 and any number, individual, identical, bottle-shaped Containers 4. Depending on the required water expansion volume then have a corresponding number of bottle-shaped Container 4 can be used. For example only two bottle-shaped container 4 is needed, so can but also the illustrated tubular distributor be used with three connecting pieces 3, a connecting piece 3 is then easy with a pressure-tight Plug closed. Alternatively, of course also a tubular distributor 2 with only two connecting pieces 3 are used. In a fault case can in this embodiment, easily a single damaged container 4 are replaced, it does not need to replace the entire expansion tank 1 to become.
- Fig. 2 is another embodiment of an inventive Expansion vessel shown, wherein the same Reference numerals as in Fig. 1 are related, if same or similar parts are concerned.
- the bubble-shaped membrane 8 is accordingly in the individual containers 4 each with its opening edge 8a inserted sealingly in the gas connection piece 10.
- the distribution line 12 has accordingly for each connection of a container 4 plug-type connecting pieces 11 with internal thread, what a screwing the container 4 with inserted membrane 8 allows.
- a bayonet or Snap connection can be used.
- the water space 6 of the respective container 4 is thus from respective cavity within the respective container. 4 formed outside the membrane 8.
- FIG. 2 shows, it can be provided in an embodiment, that the membrane 8 facing away from the opening edge in each case End is fixed, this end is 8b designated and formed like a pin.
- a holding element 14 is formed, which formed in this embodiment of a bore is through which the pin-like end 8b of the respective Membrane 8 is passed locking. Further are through the holding member 14 around openings 15th recessed in the respective container bottom to the passage of water from the distributor 2 in the container 4 or vice versa to enable.
- the retaining element 14 may alternatively, which is not shown is, even in the area of the connecting piece 3 of the Distributor 2 may be formed.
- FIGs. 3 and 4 are plan views of possible arrangements of bottle-shaped container 4 to an expansion vessel shown.
