Description of the utility model

of the company Gebr. OTTO K.G., 591 Kreuztal / Krs. Siegen

concerning: "Large capacity pressure vessel for hot water heating"

The hiring relates to a large-capacity pressure vessel for Hot water heating, which consists of a two-chamber pressure-resistant container, one chamber of which is designed to hold hot water and the other chamber of which is designed to hold a compressible medium, e.g. compressed gas.

Several types of pressure expansion vessels for hot water heating are already known. Most is a spherical one Vessel in use, which consists of two half-shells of approximately the same size; the edge is then in the connecting joint a stretchable membrane used, which the two above

Chambers separates.

A pressure expansion vessel in spherical shape is also known, which contains a bubble corresponding to the walls of the ball, which by means of an annular retaining ring is in active ©! = ment is maintained. In this pressure expansion vessel, the bladder is filled with the compressible pressure medium, e.g. nitrogen.

The above-mentioned types of pressure expansion vessels are suitable not suitable for use in larger heating systems, For example, for high-rise or multi-storey buildings, as the amount of water circulating in the heating system is too large here.

A large-volume pressure vessel is already known in which a large number of smaller pressure expansion vessels of the type specified above are used in series. Such a pressure vessel however, its structure is extremely complicated, prone to failure and difficult to repair, especially when failures occur It is not easy to determine which of the small expansion vessels in the large-capacity tank are built in, does not work. Approx. 40 to 50 such small pressure expansion vessels are required for a suitability of 10,000 liters of a suitably designed pressure vessel.

The innovation is based on the task of having one in his Construction and production as simple as possible large-scale

to create pressure vessels that are easy to maintain.

The object is achieved in that, according to the invention, a only partially in the active position resting on the inner wall of the container bubble or the like. designed to receive hot water is and that to limit the expansion or inflation of the bladder or the like. one is roughly across the Container extending partition is arranged, which, as known per se, with holes, slots or the like. is provided.

It is also a pressure expansion vessel for small amounts of water known, in which two smaller perforated containers are provided within a pressure vessel, each have a membrane. In this container, the hot water is on one side of the membrane in the respective Small container promoted, so that the nitrogen contained in the large container surrounding the small container, e.g. less than 1 atm counteracts the expansion of the two membranes. On the one hand, this embodiment is how the one described above, not for large hot water systems usable and on the other hand, through the use of the membrane, the corrosive water also enters at least partially in contact with the walls of the inner container.

When using the bladder in the innovative sense for However, the intake of hot water will be complete and with

Safety avoided having the hot water at any one Place comes into contact with the pressure vessel wall. Corrosion of the container is therefore at least due to the DHW completely switched off.

A modified embodiment of the innovation consists in that the partition in the direction of the bladder or the like. is concave.

Appropriately, the bladder or the like. locked on the partition; the lock can be arranged in the middle of the partition.

It can also be in the bladder or the like. a spacer can be provided; the spacer is expediently rod- or tubular and placed in the center of the bladder.

The spacer can or the like as a tube with holes, slots. be trained; the pipe is conveniently in Extension of the inlet connection for the hot water attached.

A useful modification of the innovation consists in that the bladder or the like. at the inlet connection with an elastic Sealing flange is provided; also at the locking point can the bladder or the like. be provided with an elastic Qummlbolzen.

According to a modified version of the innovation, the longitudinal direction of the container can be extended by inserting cylindrical rings. In this way , a standardization of the large-capacity pressure vessel, which is available in different sizes, is possible.

In the drawing , an example from implementation is shown. Show it:

FIG. 3 shows a further detail from FIG. 1.

A pressure vessel 1 designed as a standing vessel, e.g. with a capacity of 10,000 liters, has a Manhole 2 open. In the case of a smaller design of the container, the manhole 2 can be designed as an inspection opening the meaning of which is described below.

On the transverse side of the cylindrical container opposite the manhole 2, an inlet nozzle 3 is provided.

Approximately in the middle between the inlet connection 3 and the manhole 2 there is provided a partition 4 made of metal or plastic, for example, which is fixed to the walls of the container 1 is connected and holes 5, slots, holes or the like. having.

The partition 4 is in the illustrated embodiment in In the direction of the inlet connection 3, it is concave and is used to delimit a space in which a bladder 7 is arranged. This bladder 7 is used to receive the pressurized water Warm water heating and can be inflated against the pressure of a gas (e.g. nitrogen); while with the known smaller ones Pressure expansion vessels are operated with a gas pressure of 1 atm, in the present case a significantly higher one Pressure, e.g. 5 atm, provided.

The maximum expansion of the bladder 7 is caused on the one hand by the container inner wall 8 and on the other hand by the partition 4 limited. The bladder 7 is designed in such a way that, as described in more detail below, it is only in the area of the inlet connection 3 is clamped so that the pressurized water entering the bladder 7 does not come into contact with the container wall 8 at any point can occur and in no case - in contrast to the known pressure expansion vessels - does not result in corrosion.

A support tube 9 is provided as an extension of the inlet connection 3, which fulfills a multiple function. On the one hand, the support tube 9 serves as a spacer for the

-7- 4ft

Bladder 7 in its central area and extends from the inlet nozzle 3 to the partition wall 4. This is on the other side Support tube 9 with Locharn, holes, slots 10 or the like. provided so that the pressurized water or the like through these holes. can enter the bladder 7. When the gas pressure increases, the pressurized water occurs through the bores, slots or the like. above the inlet nozzle 3 out of the bladder 7 again.

As can be seen in particular from FIG. 3, the support tube 9, which may be closed at the free end 12, is with the container bladder connected, which at the point opposite the inlet connection 3 has a vulcanized threaded bolt 13 which is provided within a thickened or reinforced region 14 of the bladder 7. Of course the support tube 9 can also be open at the top at the point just indicated.

The vulcanized threaded bolt 13 is pushed through the partition 4 and by means of two nuts 16 and 17 held. Between the nut 16 and the partition 4 1st a washer 15 is provided. The locking of the bladder 7 in the area of the partition 4 can also be applied to other Way to be done.

With the size of the bladder 7 at maximum inflation captured space, a lock is particularly useful, because when you squeeze the

the same / also a squeezing of sections is effectively avoided.

As can be seen, for example, in FIG. 2, the single bubble opening is firmly connected to the inlet connection 3 or also to the support tube 9, with a reinforcing bead 20 attached the inlet opening of the support tube 9 is provided. These Reinforcement is ring-shaped and has a shoulder surface 22 in the opening in the container 1.

The reinforcement 20 merges into a wide, scabbard-shaped sealing point 21. This part is through a retaining plate 23 by means of screws, nuts 24 or the like. sealed in its margins. The sealing takes place in relation to the opening of the container 1.

In the space 6 containing the pressure vessel, a filling valve for the compressed gas and, for example, a pressure gauge 26 are provided.

In a modified embodiment of the innovation, the partition 30 (indicated by a dashed line in FIG. 1) is designed as a flat perforated disk, which is connected to the container wall at approximately the same distance from the inlet connection 3 and manhole 2.

As a bladder 7 is not suitable for the purpose of the innovation just a stretchable Qummibubble, but also a stretch-resistant one Structure. Such a stretch-resistant structure could for example consist of three layers, of which the middle one can be synthetic fabric insert.

As stated above, the container according to the innovation can also be produced in smaller sizes; in this case an inspection opening is provided instead of the manhole, whose "glazing" is removable. The distance between the inspection opening and the locking bolt in the Partition 4 is shorter than an arm's length in this case, so that you can comfortably reach the bolts by hand from the inspection opening.
