Description

The invention relates to a distributor, in particular in tube form or bar form, for connecting pipes and functional elements of a heating or cooling system, with at least one primary connection and at least one secondary connection to a tubular or bar-shaped base body, wherein the secondary connection means for displaying connected to the flow rate, which is flowed through by a distributor through the fluid.

In the prior art distributors are known in bar form or in tube form in different constructions. It is also known to design such distributors with attached, non-flow through flow displays. A generic distributor is from the DE 201 08 789 U1 known. In this case, a through-flow of the fluid flow indicator is screwed to the manifold mainly below the distributor bar. In such a known embodiment, an optical control of the current flow values of the individual heating or cooling circuits is made possible, wherein the display device only slightly contaminated over time, since it is constantly flowed through. Dirt particles are discharged. Deposits do not arise or hardly.

However, these screwed flow indicators require considerable mounting space, which is disadvantageous in the usual way limited space in distribution cabinets, in which such distributors are arranged as return manifold and flow distributor.

Based on this prior art, the present invention seeks to provide a distributor of the generic type, which requires little additional space and in which nevertheless contamination of the display device is avoided over time.

To achieve this object, the invention proposes that the secondary connection is only in line-open connection with the device for indicating the flow rate and the device is conductively connected to the interior of the base body via a third connection.

The primary connection to the base body is preferably provided on an end face of the base body. It serves to connect either the flow of a heating or cooling system or the return of such a system. The secondary connections are designed to couple connection cables for the individual heating or cooling circuits. In the base body, which is intended for the flow, the corresponding heating or cooling elements are supplied with fluid via the secondary connections. A return bar connects the lines coming back from each surface heating or cooling circuit to the secondary connections, while connecting the return of the entire system to the primary connection. Due to the fact that according to the invention, as is usual in the state of the art, a flow-through device is connected to the secondary connection, but that the secondary connection is in open connection only with the device for indicating the flow rate and the further guidance of the flow control device Fluids is passed through this device to a third terminal of the body in the interior of the body, a more compact design than previously possible. For example, in a base body, which serves as a feed bar, the flow is supplied via the primary port. Via the third connection, the medium flowing in the base body is branched off, passed through the device for indicating the flow rate and led out of this to the secondary connection of the base body, via which the fluid passed through is in each case supplied to a surface heating circuit or cooling circuit.

If the main body is connected as a return bar, fluid is supplied from a surface heating circuit or cooling circuit via the secondary connection. This fluid is directed from the secondary port directly into the flow rate indicator and exits this device via the third port, which is in open communication with the interior of the body. The total amount of fluid thus recirculated is discharged via the return at one end face of the main body.

In order to promote the compact design of the distributor, it is provided that the secondary connection is formed by a chamber of the main body, which has a first connection opening for a fluid circuit and a second connection opening for the device.

In this case, the secondary port is formed as a separate chamber in the base body, which is connected to the first connection opening either to a Flächenheizkreis laxative or connected by a Flächenheiz- or cooling circuit recirculating. The chamber has a second connection opening for the device for indicating the flow rate, wherein this device is in turn connected in a line-open manner via the third connection to the interior of the base body.

Also to promote the compact design of the distributor is also provided that the second connection opening parallel to the third Connection of the body is aligned and both open out on a surface, in particular side surface of the body.

In this embodiment, only the first connection opening of the secondary terminal is provided, for example, on the underside of the base body, while the two connection openings are provided on a side surface of the base body, namely the second connection opening for the device for displaying the flow rate and the third connection of the device leads into the interior of the body. The arrangement of the terminals on a side surface of the base body, the compact design is promoted.

Also for the same reason, it is preferably provided that the device for indicating the flow rate is formed by a molded part, which has two mutually parallel connection piece on a side surface facing the base body, which can be inserted into each of the second connection opening and the third terminal, as well as an internally connecting the connecting piece channel, wherein in the channel a flow indicator is arranged.

Characterized in that the device for indicating the flow rate is formed by a corresponding molded part, this is in a simple manner to connect to the main body and connect, wherein in the assembly target position quasi a lateral completion of the body formed by the device for displaying the flow rate in the form of the molded part which leads to a compact design of the overall element.

Particularly preferred is also provided that the device for indicating the flow rate has an adjusting means for adjusting a flow rate.

For example, a spindle can be arranged in the device with which the flow through the corresponding heating or cooling circuit can be adjusted. This makes it possible to hydraulically balance the heating or cooling circuits connected to the main body.

In this case, it is preferably provided that adjusting means is installed at an end region of the channel connecting the connecting pieces and has an externally accessible handle for its adjustment.

The handle can for example be manually operated or by means of a tool such as screwdrivers or wrenches.

To make the display of the device for displaying the flow rate well visible to the user, it is preferably provided that the device for indicating the flow rate total or at least in the region of the display means of the device consists of clear material.

It may be sufficient merely to provide the area of the display made of transparent material. But it can also consist of the entire device, in particular the entire molded part of clear material.

In order to further promote the compact design is provided that the molding is at least partially covered by the base body, wherein the base body has a recess into which the molding is suitably used, so that it is at least partially surrounded by the body.

For the same reason as well, it is provided that the molded part terminates flush with the installation target position at least with one longitudinal side surface of the main body.

Depending on whether the base body is to be used as a feed bar or as a return bar, it is possible to mount the molded part either in a first mounting position or in a relation to the first position rotated by 180 ° mounting position. By reversing the mounting position, a flow in the corresponding other direction is possible while ensuring the correct display of the flow rate. The element by means of which the flow is indicated is preferably a float element together with a compression spring. Such a float element may, for example, be arranged in the channel connecting the connecting pieces. The channel may have at one end an installation opening through which the compression spring and the float can be inserted.

When installed correctly, the fluid flows through the float and absorbs it due to the flow resistance in the direction of flow. The float is moved against the resistance of a compression spring, so that the float takes a certain position depending on the flow, which corresponds to a corresponding flow rate.

Preferably, in the area in which the float is located, a scaling is attached to the preferably transparent housing, so that the current flow can be easily read off.

If the corresponding molding is installed in a 180 ° rotated position, then this is required for a body that forms, for example, the return beam, whereas the above-described training relates to a lead beam.

It can then in turn flow the fluid via a connection piece in the device for displaying the flow rate. Even then, the float is taken along due to the flow and moved against the spring, so in turn can read off a corresponding flow rate. Since preferably the molded part is connected via a detachable plug connection with the base body, a change in the flow direction and an adaptation to the local conditions in a simple manner is possible even with already installed basic bodies. This can e.g. become necessary if, after assembly of the main body and after connection of the surface heating circuits or area cooling circuits, it is determined that the lines for the flow and return of the heating or cooling system are reversed. It can then be realized in this way with little effort, an alternative embodiment of the manifold, the advantage of the simple display of the flow rate is maintained.

In this embodiment, it can be provided that the device for indicating the flow rate is releasably secured to the base body, in particular by means of latching.

Such a latching connection is easy to implement, wherein the detent is designed such that in the mounting position desired locking with the body is achieved. By a corresponding tool engagement, the detent can be canceled and the molded part are released from the body, for example, to replace this or to install in another position can. By securing the locking, unintentional removal or even vandalism is prevented.

A particular embodiment, which makes it possible to form distributors of different lengths, is seen in that the base body consists of at least one, preferably a plurality of close-coupled main body segments and at the ends of the base body formed therefrom provided head plates optionally with a primary fluid connection part, each Segment has a device for displaying the flow rate and a secondary port.
