Description

Apparatus for operating tank storage systems in the solid-lined composite with pipe systems for fluids

TECHNICAL AREA

The invention relates to a device for the operation of tank storage systems in the solid-lined composite with fluid piping systems, mainly liquid products, but generally also suitable for gaseous products, in particular for application in high microbiological quality requirements subject product handling and product transfer in the food and beverage industry, pharmacy and biotechnology, with the tank storage system comprising at least one tank, with a pipe system consisting of at least one pipeline, either with one each in a tank bottom of the respective tank or with one respective tank associated valve manifold, which is designed as an elongated hollow structure which ascends from bottom to top, usually a vertical course and has the connection openings for connecting its interior with each of the pipes , and each with a disc valve, which is arranged in each connection between the pipe and the associated connection opening and this connection in close proximity to the hollow structure switches.

STATE OF THE ART

Conventional piping systems in the abovementioned fields of application, which generally meet the high demands on product quality, have so-called valve matrix systems in which a large number of valves for switching the manifold pipelines of the respective process are combined in so-called valve blocks. The pipelines from and to the tanks of the tank storage system are brought to these valve blocks. Such solid-pipe systems may harbor risks of undefined microbiological processes that may occur in the more or less long pipelines between the valves and the process tank. Also due to thorough basic planning of the process plants, these potential dangers can not always be reliably controlled or eliminated. Details of this problem can be found in DE 101 08 259 C1.

Based on the above problem, DE 101 08 259 C1 proposes a piping system of the initially identified type, in which the process lines and function valves are mounted directly under the respective tank outlet. This piping system has been proven in practice in the meantime; it is in the company publication Tuchenhagen Brewery Systems, ECO-Matrix ^®, 223d-10/06, described in more detail under the name ECO-Matrix ^®, and in particular under the aspect of cost and the influence on the product quality.

In the case of the latter preheating system, the functional valves can be fastened either laterally on the tank outlet tree, the so-called valve distributor tree, or vertically on the bottom flange of the tank. This piping technique significantly minimizes the formation of contamination and its subsequent distribution in the process system. The piping system, which is separate from the tank, enables complete product emptying and tank-independent cleaning. Compared to traditional systems, this piping technique reduces instrumentation costs while optimizing the process for nearly lossless production operation.

In traditional piping systems of the type described at the outset and in so-called. ECO-Matrix ^® -Verrohrungen predominantly sophisticated, leak secured valves double sealing valves are used, so-called. Double seat valves and so-called., Are used, which are also referred to as a mix-proof configured valves. As a double-seat valves valves are designated with two independently operable Schließgliedem, each closure member having a sealing point and between the sealing points a leakage chamber is arranged, which has at least one connection to the environment of the double seat valve. A double seal valve is a valve having a single closure member having two axially spaced seal locations therebetween where the leakage space described above is arranged. These two leakage-protected globe valves combine in themselves all the required properties that today in their entirety can be required by a process valve in the field of application in question, wherein, if necessary, the so-called seat cleaning is also included. But these lift valves are structurally correspondingly expensive and therefore costly.

DE 101 08 259 C1 also mentions so-called disc valves having two seals which are spaced apart on the sealing circumference of the disk-shaped closing member and between which an annular circumferential leakage cavity is arranged, which connects to the surroundings of the disk valve via at least one connecting path is. Further details on how to design the known piping system in connection with leak-proof disc valves concretely are not found in DE 101 08 259 C1.

In addition, in particular in a plurality of tanks of a tank storage system, if they are arranged in rows, in the elongated piping of the piping system according to DE 101 08 259 C1, but also generally in traditional piping systems with elongated pipes, special precautions necessary to length changes due to temperature changes and to compensate for the associated demands. A so-called expansion compensator with hygienic properties, which represents a sophisticated component and at all required locations in the piping system and with the vorg. Problem is manageable, is known for example from WO 01/25670 A1. In DE 101 08 259 C1, however, the entire strain and stress problem is not discussed, which also in the use of disc valves of vorg. Art plays a special role and decisively determines the operational safety and stability of a process plant.

In the document DE 900 763 C a compensation arc is described, there referred to as U-balancer, with the length changes due to temperature changes compensations can be compensated. Fig. 1 of this document shows a U-stabilizer, which is contracted by the heating of the pipeline, and Fig. 2 also shows a U-balancer, which is spread by the heating of the pipeline. These known per se and usually used in piping systems with elongated pipes expansion elements whenever they are deformed as intended generate reaction forces on the connected pipe strands, which must be recorded on benchmarks. DE 900 763 C is based on the object, the thermal expansion of any pipe so in per se known expansion members, such as the vorg. U-balancer, in that the fixed point pressures, caused by bias and heating, are canceled. The proposed solution is characterized by a in contrast to the hot pipe cold lever or cold pipe to the warmer lever which is arranged so that from the temperature or length difference of these elements ne adjusting movement to produce a reactionless expansion compensation arises.

It has been shown that with higher product quality and safety and when using double-seat valves and / or double-sealing valves, the piping system according to DE 101 08 259 C1 represents the more economical alternative to traditional piping systems. For piping systems according to DE 101 08 259 C1 using leak-proof disc valves so far exist no concrete solution proposals, although such disc valves are much cheaper than double-seat or double-seal valves.

When economic considerations take precedence over product quality and safety, so-called open piping systems are used in the beverage industry, especially in breweries, in which preferred are simple-sealing disk valves, so-called single disk valves, but also leak-proof disk valves with two axially spaced ones , circumferential sealing points, between which a leakage cavity of vorg. Art is arranged for use. The so-called distribution panels (eg DE 298 21 813 U1) are here a preferred embodiment, so-called pipe fences represent another variable. Nevertheless, in order to ensure a relatively high investment cost with a high degree of flexibility in terms of a variety of necessary and / or desirable piping connections between, for example, a fermenter tank outlet and a number of other functional units.

Thus, in the case of the well-known, manually operated distributor arrangements, the so-called distributor panels or pipe fences, for example the task of several tanks, for example fermentation tanks in a fermenting cellar or other functional units, in each case via their tank outlet line, which is connected to a pipe fence, if necessary connect to a Jungbier filling line or a Jungbier emptying line or a Yeast harvesting line or a drainage line or a tank cleaning line. Since both the tank outlet line and the other aforementioned lines in the pipe fence each end in a pipe connection, which in each case via a directly upstream shut-off device, usually the disk valve, can be shut off, two selected on the basis of the desired connection pipe connections, and so that the associated different function lines, which have a defined, fixed distance from each other, are connected to one another via a detachable connecting bow. Depending on the arrangement of the pipe connections to be connected to each other while the connection sheet is provided with a hinge, so that the same connection sheet, the optional connection of the candidate pipe connections can be performed together.

The manual connection of the pipe connections with each other is still the rule in practice. This procedure is labor-intensive and thus expensive and can also be faulty if accidentally wrong lines are assigned to each other. Faulty connections can have serious consequences if, for example, enemy liquids are mixed together (detergents such as acid or lye, for example, enter the beer) or if high-quality product is mistakenly discarded via the drain. While fixed piping in accordance with DE 101 08 259 C1 with remote-controllable double-seat and / or double-sealing valves offers maximum product quality and safety with economic advantages over traditional solid piping, open piping systems in the form of distributor panels or pipe fences in connection with disk valves can not be undercut in terms of capital outlay , Their manual handling is labor-intensive and thus expensive and can also be faulty. Highest product quality and safety can not be achieved. Automated handling of open piping systems, if it is even possible, largely eliminates the investment costs saved.

Experts have long sought to combine the advantages of the two well known piping systems, solid tubing and open piping systems in a new piping system. The preheating system according to DE 101 08 259 C1 in its basic structure offers the basis for this.

It is an object of the present invention to further develop the respective device of the generic type in such a way that it is constructed in a simple and cost-effective manner and meets the highest demands on the quality of the fluid product treated in the tank storage system with high operational reliability.

SUMMARY OF THE INVENTION The object is achieved by a device having the features of claim 1 or independent claim 4. Advantageous embodiments of the devices according to the invention are described in the respective subclaims.

The present invention is based in a first basic concept on the basic features of the piping system according to DE 101 08 259 C1 and provides a practical solution for the use of butterfly valves, regardless of whether they are single-disc valves or leak-proof. cherte disc valves, so-called double disc valves, acts. An essential solution element is a compensation arc in the broadest sense as part of the respective pipeline in the area of the valve manifold tree. Either this compensating arc partially encloses with its flanks the valve manifold or it is adjacent to one of its flanks of this valve manifold.

Since the bottom of the respective tank generally tapers downwards, the valve manifold designed as a hollow structure is expediently arranged at the lowest point of the respective tank bottom. If the tank bottom shape is designed to be axially symmetrical with respect to the longitudinal axis of the tank, which is the case with most tank shapes used in practice, the longitudinal axis of the hollow structure is arranged coaxially with the longitudinal axis of the tank.

The present invention dissolves in a second basic concept of the features of the Vorrohrungssystems according to DE 101 08 259 C1 insofar as now the valve manifold tree no longer opens directly into a tank bottom of the respective tank, but is connected to the respective tank via a pipe and this in the upper end of the valve manifold tree opens.

The embodiments of the device according to the invention which are described in detail below can be applied without restriction to each of the two basic concepts of a tank storage system described above, in the solid-lined composite with pipe systems for fluids.

With a first arrangement variant of the compensating bow, it is possible to realize piping systems in which the connection openings are provided either on one side and in series or on both sides and in each case in a row arrangement on the valve manifold, wherein in the second case mutually adjacent connection openings are offset axially relative to each other. For the piping of the pipeline system there are no restrictions on their arrangement and their course. They can run in a single plane parallel to the longitudinal axis of the valve manifold tree, they can be connected in two the parallel planes which are arranged on one side of the valve manifold and oriented parallel to the longitudinal axis thereof, or they may extend in two mutually parallel planes, which are oriented parallel to the longitudinal axis of the valve manifold and accommodate the latter between them. In addition, an arrangement is possible in which the pipes of the pipe system extend in planes which are oriented parallel to the longitudinal axis of the valve manifold and cross at right angles. In this regard, intersecting pipelines require that the connection openings are provided on one side and in each case in a row arrangement on the valve distributor tree, wherein adjacent connection openings are each offset axially relative to each other and by 90 degrees.

The second arrangement variant of the compensating bow is to be used in each case in conjunction with the first, when the connection openings are provided on both sides, in each case opposite one another and in each case in a row arrangement on the valve manifold. This solution excludes the arrangement of the piping of the pipe system in a single plane parallel to the longitudinal axis of the valve manifold. The pipelines of the pipe system are then to be arranged in mutually parallel planes. The second arrangement variant of the balance sheet is also to be used in conjunction with the first, when the pipes of the pipe system in planes which are oriented parallel to the longitudinal axis of the valve manifold tree, intersect at right angles and the connection openings on both sides, each opposite each other and each provided in a row on the valve manifold are, wherein axially adjacent pairs of connection openings are offset in each case by 90 degrees.

With the first arrangement variant of the compensating bow alone or with a combination of the first with the second arrangement variant of the compensating bow, all conceivable piping can be carried out, which consists of a row or matrix arrangement of the tanks of a tank storage system in direct connection with the respective valve manifold in the region Tank bottom (first basic concept) or the valve manifolds in the respective connection to the associated tank (second basic concept) result. Clear and visually pleasing piping under the above-mentioned arrangement conditions are achieved, in particular, when, as proposed, the pipe valve receiving female pipe connection is oriented in a second escape direction, which is parallel to the first direction of escape of the connected pipe sections of the pipeline.

There are no special conditions attached to the geometric design of the compensating bow in the broadest sense. It is essential that the flanks of the compensating bow have a sufficient deformability with respect to the connection point of the pipe connection receiving the disk valve. The flanks of the balance arc may have a converging to diverging course toward its open side.

Simple and easily adaptable to the respective piping conditions balance sheet are obtained according to a further proposal in that the balance sheet is U-shaped and consists of three straight pipe sections, which are oriented at right angles to each other and connected to the balancing pipe sections of the pipe each connected via a 90-degree arc.

Another inventive idea is that the balance sheet has a connection opening in a portion adjacent to the valve manifold and that the connection opening and the connection opening are connected to each other via the pipe connection receiving the disk valve. This basic solution does not require a special embodiment of the disc valve. The latter can be designed as leak-proof double-disk valve or as a single-disk valve.

Finally, another essential inventive idea is that the connection point of the pipe connection at the compensating bow with respect to the first escape direction of the pipe sections of the pipe connected to the equalizing bow at least one distance, the sliding movements of the pipe sections in the first direction of escape allows. These displacement movements are essentially changes in the length of the pipes due to temperature changes. The deformability of the flanks of the balance arc is over the vorg. determinable minimum distance so that under all conceivable operating conditions the forces occurring at the disc valve and the pipe connection in the area of the valve manifold lead to no damage to the components and the connection points and to no impairment of the function of the disc valves.

The design of the designed as an elongated hollow structure valve manifold tree is particularly simple if, as further proposed, it is designed as a cylindrical tube.

As an alternative to the embodiment of the hollow structure in the form of a cylindrical tube, it is further provided that the hollow structure is composed in each case of an aggregation of individual housing parts which are fluidly interconnected in the direction of the longitudinal axis of the hollow structure and each have at least one connection opening. These housing parts can be either discrete, separate parts joined to the hollow structure in its entirety, or a one-piece whole in which the individual housing parts are firmly bonded together. In both embodiments, the housing parts are formed according to another proposal, if necessary, different sizes, so that at these housing parts at least one connection opening can be performed, which has a dependent on the size of the respective associated housing part passage cross-section. Connection openings with different sized passage cross sections on a housing part are also provided. Thanks to this variety of designs, the hollow structure in all of its flow-through areas can be adapted to the fluidic requirements of the connected pipelines of different nominal diameters. According to a first embodiment, the pipe connection receiving the disk valve opens into the latter perpendicular to the longitudinal axis of the valve manifold. This embodiment is geometrically relatively simple and correspondingly easy to manufacture. A second embodiment provides that the pipe valve receiving the pipe connection opens with rising to the longitudinal axis of the valve manifold tree course in the latter. This embodiment is complex in terms of manufacture, but it can be emptied completely more complete.

The hollow structure can be completely emptied and properly cleaned, if its lower end facing away from the tank is connected to a pipe for cleaning.

The invention provides in the pipe connection between the connection opening on the hollow structure and the connection opening in the balance sheet before a disk valve, which is formed depending on the process conditions either as a single disk valve or as a leak-proof double-disk valve (DE 28 47 038 A1, DE 29 48 534 C2 DE 30 42 895 C2).

The single-disk valve has on the circumference of a disc-shaped closing member on a single circumferential sealing point. The double disc valve is used in two different embodiments. In one embodiment, two disc-shaped closing members are provided in the same direction, each having at its periphery a circumferential sealing point, wherein between the two axially spaced sealing points an annular circumferential leakage cavity is arranged, which is connected via at least one connection path with the environment of the disc valve. The other embodiment has a single disc-shaped closing member having at its periphery two axially spaced, circumferential sealing points, between which an annular circumferential leakage cavity is arranged, which is connected via at least one communication path with the surroundings of the disc valve. The basic design of a mix-proof designed disc valve of the latter type is for example from the DE-A-22 29 978 known. With such a disc valve, but also with the former type, a cleaning of the leakage cavity is possible in the closed position.

The double-disk valve with two disk-shaped closing elements which can be switched in the same direction is again designed in three variants. A first variant is characterized in that the disc-shaped closing members are switched dependent on each other and synchronously, in a second variant, the disc-shaped closing members are switched interdependent and delayed and in a third variant, the closing members switch independently.

With the third variant, the double-disc valve, as also proposed, be subjected to a seat cleaning by a respective partial opening movement of its closing members such that during the partial opening movement of a closing member the other is not moved and remains closed. A related kinematics requires that the one sealing point remains in its closed position, while the other sealing point is transferred to a partial open position, so that brought for the purpose of seat cleaning on the exposed sealing point cleaning liquid from the associated pipe section and the leakage cavity in the environment the disc valve can be removed.

Both the single-disk valve and the leak-proof double-disk valve in the two embodiments described above are each actuated either manually or by means of a remotely controllable drive.

It is further proposed that the tank-side end of the valve manifold can be shut off from the associated tank by means of a disk valve. Such a shut-off facility creates the conditions for a separate revision or inspection of the associated tank on the one hand and the valve manifold and the connected pipe system on the other.

DETAILED DESCRIPTION

FIG. 1 shows the lower end of a cone-shaped tank bottom 1.1a of a tank 1.1 of a tank storage system 1, which may consist of a number i = 1 to n tanks 1.1 to 1.n, for example in a row-shaped arrangement. Each tank bottom 1.1a to 1.na of the respective tank 1.1 to 1.n opens at its lower end respectively into a valve manifold B1 to Bn (first basic concept), which is preferably designed as an elongate hollow structure B1a to Bna in the form of a cylindrical tube , A longitudinal axis L of the valve manifold tree B1 to Bn and thus of the hollow structure B1a to Bna is oriented vertically and aligned coaxially with the longitudinal axis of the respective tank 1.1 to 1.n. At the tank bottom 1.1a to 1.na remote from the lowest end of the respective hollow structure B1a to Bna a third pipe system 4, for example, arranged for cleaning.

The inventively proposed device is equally applicable to tank storage systems 1, in which the respective tank bottom 1.1a of the tank 1.1 does not open directly, in the manner described above, in an associated valve manifold B1, but where the respective Ventilvertei- 1 to Bn with the geometry described above, with a generally vertical upward slope from the bottom to the top, with the associated tank 1.1 to 1.n connected via a pipeline 5 (FIG. 1, designated there but not shown) (second basic concept). The tanks 1.1 to 1.n can assume any arrangement and positioning which is not encompassed by that of the valve manifold tree B1 to Bn directly opening out in a tank bottom 1.1a to 1.na of the respective tank 1.1 to 1.n, eg laterally on the valve manifold tree B1 to Bn lying or standing arranged tanks 1.1 to 1.n. The illustrated pipeline 5 may be a vertical or a possibly inclined end section in the region of its end section connected to the valve distributor tree B1 to Bn. The inclined end portion, which extends in the limit case horizontally, finds with a corresponding pipe bend connection to the upper end of the valve manifold tree B1 to Bn. The embodiments of the device according to the invention described below are fully applicable to the two basic concepts described above of the tank storage system 1 and the valve manifold tree B1 to Bn in its respective arrangement to the tank 1.1 to 1.n.

A first pipe system 2 (FIGS. 1a and 1), for example for filling the tank 1.1 to 1.n, consists in the most general case of a first group of pipes 2.1 to 2.n, whose pipes 2.1 to 2.n are arranged in rows and in a row single plane parallel to the longitudinal axis L of the hollow structure B1a to Bna are arranged. The limited in the embodiment of two pipes 2.1 and 2.2 piping is passed at a distance x, relative to the longitudinal axis L, the hollow structure B1a to Bi n.

The respective pipe 2.1 and 2.2 is formed in the region of the valve manifold tree B1 to Bn in the form of a U-shaped compensating bow AB, which in a plane perpendicular to the longitudinal axis L of the valve manifold B1 to Bn latter ren partially with its two flanks AB ¹ and AB In a section adjacent to the valve distributor tree B1 to Bn, in the exemplary embodiment, the compensating bend AB has, in the exemplary embodiment, a connection opening V in the right-hand second flank AB ", which has a connection opening V associated connection opening A in the hollow structure B1a to Bna corresponds. The connection opening A and the connection opening V are connected to one another via a pipe connection RV receiving a disk valve S. In the exemplary embodiment, the disk valve S is a leakage-proof double-disk valve S **, which alternatively can also be designed as a single-disk valve S ^* . The connection point of the respective pipe connection RV on the leveling sheet AB has, relative to a first escape direction F1 of the respective pipe sections a 'and a "of the pipes 2.1 and 2.2 connected to the leveling curve AB at least the predetermined distance x, the displacement movements of the pipe sections a', a "in the first escape direction F1 permits. In the exemplary embodiment, the pipe connection RV is oriented in a second escape direction F2, which runs parallel to the first escape direction F1. As shown, the U-shaped balance arc AB preferably consists of three straight pipe sections which are oriented at right angles to each other and which are connected to one another and to the pipe sections a ', a "via a 90-degree arc.

The above-described U-shaped configuration of the balance sheet AB and the arrangement of the connection opening V with respect to the connection opening A is not mandatory. It can take any form in which the flanks of the compensating bow AB have a converging to diverging course towards its open side. It can also have, for example, the form of a so-called Lyra arch. It merely has to ensure that its connection point forms a bendable flank AB 'or AB "to the however oriented pipe connection RV The second escape direction F2 can also be oriented perpendicularly or obliquely to the first escape direction F1.

In the same way as the first pipe system 2 is a second pipe system 3 (Figure 1a), for example, for the emptying of the tank 1.1 to 1.n, formed, which consists of a second group of pipes 3.1 to 3.n, the pipes 3.1 to 3 .n are also arranged in a row in relation to each other and in a single plane parallel to the longitudinal axis L of the hollow structure B1a to Bna. Also in the exemplary embodiment pipelines 3.1 and 3.2 Restricted piping is guided past the hollow structure B1a to Bi n at the distance x. The respective pipe 3.1 and 3.2 is formed in the region of the valve manifold tree B1 to Bn in the form of a further U-shaped compensating arc AB, which in a plane perpendicular to the longitudinal axis L of Ventilvertei- lerbaumes B1 to Bn latter partially with its flanks AB 'and AB In the section adjacent to the valve distributor tree B1 to Bn, in the exemplary embodiment, the compensating bend AB has a connection opening V in the left-hand first flank AB 'relative to the display position, which has an associated connection opening A in the hollow structure B1a to Bna The connection opening A and the connection opening V are connected to one another via a pipe connection RV receiving a disk valve S. In the exemplary embodiment, the disk valve S is a leak-proof double disk valve S **. The connection point of the respective pipe connection RV on the leveling sheet AB faces one first escape Direction F1 of the respective pipe sections a 'and a "of the pipes 3.1 and 3.2 connected to the leveling curve AB at least the vorg. In the exemplary embodiment, the pipe connection RV is oriented in a second escape direction F2, which runs parallel to the first escape direction F1. as shown, from three straight pipe sections, which are oriented at right angles to each other and which are connected to each other and to the pipe sections a ', a "in each case via a 90-degree arc.

Since the pipes 2.1, 2.2 and 3.1, 3.2 of the pipe system 2, 3 run in a single plane parallel to the longitudinal axis L of the valve manifold tree B1 to Bn, their respective first escape direction F1 coincide and the respective second escape direction F2 of these pipes run in a common another level. For the third pipe system 4, for example a pipe for cleaning, the geometrical statements of the first pipe system 2 apply, since, as FIG. 1a makes clear, the respective pipe guides are congruent. The disk valves S, S ^* , S * ^* are each manually operated in the embodiment. They are readily accessible by means of a remotely controllable drive, for example example, in the form of a pressure medium-loaded spring / piston drive, actuated.

The tank-side end of the valve manifold B1, B2, ..., Bi, ..., Bn is compared to the associated tank 1.1, 1.2, ..., Li, ..., 1.n each by means of a disc valve S, which in present trap is designed as a single-disc valve S *, lockable.

The hollow structure B1a to Bna can each also be composed of an aggregation of a number j = 1 to m individual housing parts, for example, any hollow structure Bia consists of the housing parts Bia.1 to Bia.m, which in the direction of Longitudinal axis L are fluidly interconnected and each having at least one connection opening A. These housing parts Bia.1 to Bia.m may be designed to be of different sizes, in which case, for example, the respective connection opening A may have a passage cross-section which is dependent on the size of the respectively assigned housing part Bia.1 to Bia.m. If there is more than one connection opening A on the respective housing part Bia.1 to Bia.m, differently sized passage cross-sections of the connection openings A are also executed if required.

From Figure 1 it can be seen that the pipe joint RV opens perpendicular to the longitudinal axis L of the valve manifold tree B1, B2 Bi, ..., Bn in the latter. It is also proposed that the pipe connection RV opens with the longitudinal axis L of the valve manifold tree B1, B2, ..., Bi, ..., Bn ascending course in the latter. The latter embodiment ensures in any case complete emptying of the pipe joint RV and the associated disk valve S, S ^* , S **.

A second embodiment of the device according to the invention (Figures 2, 2a) differs from the first embodiment according to Figure 1 in that the connection openings A are provided on one side and in series on the valve manifold tree B1 to Bn. The pipes 2.1, 2.2 and 3.1, 3.2 and 4 of the pipe system 2, 3, 4 are, as in Figure 1, in a single plane parallel to the longitudinal axis L of the valve manifold tree B1 to Bn. An operator B has unimpeded access, for example, to the disc valve S, S ^** from the side of the second flank AB "of the compensating bow AB.

The plan view of the device according to FIG. 2, FIG. 2a, makes it clear that the pipe systems 2, 3 and 4 extending parallel to three, arranged in rows, form B1a to B3a via the compensating bend AB provided on the valve manifold B1a to B3a over a sufficient length Possibility of length changes.

3a and 3b illustrate the top view of the pipe systems 2, 3 and 4 of the device according to the invention, as described in detail on the basis of Figures 1 and 1a on a single valve manifold tree B1a, in its course parallel to three illustrated, row-shaped valve assembly shown. Divider B1 a to B3a. Here, too, it becomes clear that the pipe systems 2, 3 and 4 have a sufficient possibility of length changes via the respective compensating curves AB provided on the valve manifold tree B1a to B3a. The illustration according to FIG. 3 is identical to that according to FIG. 1.

The third embodiment of the device according to the invention according to Figures 4 and 4a differs from the first embodiment according to Figures 1 and 1a in that, based on the presentation position, the horizontally extending third pipe system 4 via the vertically extending pipe joint RV from below to the valve manifold B1a is connected. The deformability of the flanks AB 'and AB "of the leveling bow AB of the pipe system 4 is not impaired by this pipe guide Instead of a bending stress, the pipe joint RV and the disk valve S, S ^** arranged there essentially undergo a torsional stress.

In the figures 5 and 5a, a device according to the invention is shown in a fourth embodiment, in which the connection openings A on both sides, each opposite each other and each in a row on the valve manifold tree B1 to Bn and accordingly provided on the hollow structure B1 a to Bna and the pipeline guide via three valve manifolds arranged in series B1 to B3 or hollow structures B1a to B3a are shown (Figure 5a). The third pipe system 4 is, according to the embodiment according to Figures 4 and 4a, connected vertically from below to the valve manifold tree B1 to Bn. By way of example, the disk valves S are in each case single-disk valves S ^* , which are readily interchangeable with leak-proof disk valves S **. The pipelines of the pipe system 2, 4 on the one hand and the pipe system 3 on the other run in two mutually parallel planes, which are arranged on one side on the valve manifold B1 to Bn and are oriented parallel to the longitudinal axis L. Since the levels of the pipes 2,4 and 3 now have a distance from each other, the first escape directions F1 no longer coincide, so that compared to the uniform for all horizontal pipe connections RV second escape direction F2 now two different distances x, namely a distance X _2nd of the first pipe system 2, which is also effective for the third pipe system 4, and a distance X _{3 of} the second pipe system 3 are given. The smaller distance X ₃ is dimensioned so that the required sliding movement of the pipe sections a \ a "of the pipes 3.1 and 3.2 of the second pipe system 3 in the first escape direction F1 is ensured in each case.

It can also be seen that this solution makes use of the second arrangement variant of the compensating sheet AB in conjunction with the first arrangement variant of the compensating sheet AB. The compensating arc AB of the second pipe system 3 encloses with its flanks AB ', AB "the respective valve distributor tree B1 to B3 (first arrangement variant), while the compensating curve of the first pipe system 2 with one of its flanks AB', AB" in the exemplary embodiment first edge AB ¹ , the respective valve manifold tree B1 to B3 is adjacent (second arrangement variant).

The arrangement principles described above of the device according to the invention for tank storage systems 1 in a row-like arrangement can be transferred to matrix-type arrangements (FIGS. 6 and 7) in which the respective pipelines of the pipeline systems 2 and 3 and optionally 4 extend in planes, which are oriented parallel to the longitudinal axis L of the valve manifold tree B1 to Bn and intersect at right angles. In this case, in the two exemplary embodiments, the connection openings A are provided on one side and in a row arrangement on the valve distributor tree B1 to B6 and accordingly on the hollow structures B1a to B6a, wherein adjacent connection openings A are offset from one another axially and by 90 degrees.

The pipelines 2, 3 which are led past the respective hollow structures B1a to B6a are connected in parallel to the respectively incoming and outgoing pipelines 2, 3 (FIG. 6) or they each extend in a meandering manner and are each in series connected to the respective inlet and outlet pipe 2, 3 (Figure 7).
