In a further embodiment of the aforementioned embodiment shape are according to claim 3, the ends of the connection tube-shaped direct line in spacer sleeves tight used in the extension of horizontal an connecting piece of the flow connection and the lower connection final fitting in the lower water channel are provided. The spacers do not only take over the water conductive connection between the direct line and the Flow connection or the lower connection fitting, son They serve when connecting the connecting piece of the Flow connection and the lower connection fitting with a heating panel also as an abutment, especially when Pressure welding. Such spacers can be different be designed like this. For example, they have Spacer sleeves on the side for pressure welding. You can also use smooth faces between the be tightly integrated between two sheets of a heating panel. It is also possible that the spacer sleeves are short have axial stubs with which they have recesses in push through the sheet forming a heating panel. Derar ring beads may be radially outward be flanged to the spacer sleeves on the sheets to be determined. The spacers can be round, oval or be polygonal.

The connecting piece can in particular components of form spherical housings. You can be one-sided or be attached in one piece to the housing on both sides. in the In the case of the flow connection and the return connection the spherical housing also carry sleeves with internal or  External threads, which are then connected to the customer's heating water can be coupled or returned.

The flow connection can be independent of the return flow finally be assigned to a valve radiator. He can but also be connected to it at a distance. This can be done by a connecting plate, the header the housing, between the housing and the connector closing sleeves or at the free ends of the connecting sleeve sen can be attached. Furthermore, flow connection and return connection can be connected by a pipe section. The pipe section can form part of one of the housings.

1 1, a valve element is in the Fig. Designated by a heating panel 2 to 4. The heating panel 2 is composed of two profiled sheets 3 , 4 , whereby a lower horizontal water channel 5 , an upper horizontal water channel 6 and a plurality of horizontal water channels 5 , 6 connecting vertical water channels 7 are formed ge. The circumferential side of the channels 5-7 , the Ble che 3 , 4 are tightly connected.

Trapezoidal air baffles 8 are attached to the outside of the sheet 4 adjacent to a wall in the assembled position of the valve heating element 1 . As a result, who formed the vertical chimneys 9 ( Fig. 2).

In the area of the end face 10 of the heating panel 2 , a valve set 11 is provided on the back ( FIG. 1). The valve assembly 11 is composed of a lower connection fitting 12 , a riser pipe 13 , an upper connection fitting 14 and a thermostatic valve 15 . The lower connection fitting 12 consists of a spherical housing 16 with a flattened side 17 and a cylindrical connecting piece 18 on the side 17 opposite the flattened side. At the connection piece 18 is joined by pressure welding to the outside of the sheet 4 of the heating panel 2 . For this purpose, a spacer sleeve 19 is incorporated in the lower water channel 5 between the two sheets 3 , 4 . The housing 16 is conductively connected to the lower horizontal leg 20 of the riser pipe 13 . The upper horizontal leg 21 of the riser pipe 13 is connected to the upper connection fitting 14 . Depending on the position of the thermostatic valve 15 , the riser pipe 13 is then conductively connected to the upper water channel 6 or separated from it.

On both sides of the vertical central transverse plane MQE of the heating panel 2 , the flow connection 22 for the heating water and the return connection 23 are provided at a standardized distance A of 50 mm from each other. As in this case the Figs. 2 and 4 reveal in more detail, consist of both the flow connection 22 and the return port 23 each consist of a spherical housing 24, 25 with a zylin-cylindrical connection pieces 26, 27 as well as from an open to un th connecting sleeve 28, 29 for connection to the heating water supply 30 or heating water return 31, not illustrated in any more detail and indicated only by an arrow.

In the lower water channel 5 is an extension of the connection piece 26 of the flow connection 22, a ring-shaped spacer 32 between the sheets 3 , 4 of the heating panel 2 is inserted and tightly connected by pressure welding with the sheets 3 , 4 and with the connecting piece 26 of the before run connection 22 . Between this spacer sleeve 32 and in the extension of the connecting socket 18 of the lower connection fitting 12 of the valve set 11, the spacer sleeve 19 extends through the lower water channel 5, a direct line 33 in the form of a round connecting tube (see also FIG. 5). The ends 34 , 35 of the direct line 33 are inserted tightly into the walls of the spacer sleeves 19 , 32 .

In an extension of the connecting piece 27 of the Rücklaufan circuit 23 , a spacer 36 is pressed against a peripheral bead 37 of the direct line 33 in the lower water channel 5 . The spacer 36 determines the position of the return port 23 relative to the Vorlaufan circuit 22 and also allows the determination of the return port 23 by pressure welding on the heating panel 2nd

If the thermostatic valve 15 is open, the Heizwas water flows from the heating water supply 30 via the Vorlaufan circuit 22 and the direct line 33 to the lower connection fitting 12 . From here, the heating water passes through the riser pipe 13 to the upper connection fitting 14 and via this into the upper water channel 6 . From here, ver shares the heating water through the vertical water channels 7 and reaches the lower water channel 5 on the circumferential side of the direct line 33 in the Rücklaufan circuit 23 , from where it then flows into the heating water return 31 .

The variant illustrated in FIGS . 6 and 7 egg nes valve radiator 1 a shows two spaced apart heating panels 2 , 2 a. The heating panels 2 , 2 a are constructed like the heating panel 2 of FIGS . 1 to 4, so that a further explanation seems to be unnecessary.

However, the supply connection 22 a, the return connection 23 a, the valve set 11 a and the transfer of the heating water from the supply connection 22 a to the valve set 11 a and with the thermostatic valve 15 open from this to the return connection 23 a were changed.

The flow connection 22 a now consists of a spherical housing 24 a with two diametrically opposite abge cylindrical connecting piece 26 a and a downward connection sleeve 29 a. The connecting piece 26 a are welded between the sheets 4 , 4 a of the heating panels 2 , 2 a. For this purpose, a distance sleeve 32 , 32 a is provided as an abutment in the lower water channels 5 , 5 a of the heating panels 2 , 2 a, so that the pressure welding can be applied.

The lower connection fitting 12 a of the valve assembly 11 a consists of a spherical housing 16 a with two dia metric connecting pieces 18 , 18 a, which are also placed between the sheets 4 , 4 a of the heating panels 2 , 2 a. Di punch sleeves 19 , 19 a in the lower water channels 5 , 5 a also serve as an abutment for the application of the pressure welding process. In addition, the spacer sleeves 19 , 32 and 19 a, 32 a serve the storage of direct lines 33 , 33 a for the heating water in the form of round connecting pipes, which pull the lower water channels 5 , 5 a in the longitudinal direction.

The riser pipe 13 of the valve assembly 11 a is attached with its lower horizontal leg 20 inside the valve radiator 1 a to the spherical housing 16 a conducting water.

The return port 23 a is in principle formed as the flow port 22 a. It comprises a spherical housing 25 a with two diametrical cylindrical connecting piece 27 , 27 a, which are placed between the sheets 4 , 4 a of the heating panels 2 , 2 a, and a downward opening fene not shown in detail according to the connecting sleeve 29 a of the flow connection 22 a. In extension of the connecting piece 27 , 27 a of the return port 23 a are spacers 36 , 36 a in the lower water channels 5 , 5 a, which allow the return water from the lower water channels 5 , 5 a to get into the return port 23 a can. The air baffles 8 are in this embodiment between the two heating panels 2 , 2 a.

Referring to FIGS. 6 and 7 passes therefore the heating water from the Heizwasserzuführung 30 via the lead terminal 22 a in the direct lines 33, 33 a. From here, the heating water flows from both sides into the lower connecting arm 12 a and then via the riser 13 to the upper connection fitting, not shown. When the thermostatic valve is open, the heating water thus reaches the lower water channels 5 , 5 a via the upper water channels and the vertical water channels in the heating panels 2 , 2 a, which are not illustrated, and from here via the return connection 23 a to the heating water return 31 .

The embodiment of a valve heater 1 b illustrated in FIG. 8 corresponds in principle to that of FIGS. 1 to 4, but with the difference that the flow connection 22 is now closer to the valve assembly 11 than the return connection 23 . For this purpose, a spacer sleeve 38 is now used in the lower water channel 5 b of the heating panel 2 b in extension of the connecting piece 27 of the Rücklaufan circuit 23 . This serves both as an abutment for the application of the pressure welding process and for transferring the heating water from the lower water channel 5 b into the return connection 23 and from this to the heating water return 31 . For this purpose, corresponding bores 39 are machined into the spacer sleeve 38 . The spacer sleeve 32 in the extension of the connecting piece 26 of the flow connection 22 is dimensioned as in the embodiment form of FIGS. 1 to 4 in relation to the cross section of the lower water channel 5 b so that a sufficiently large amount of heating water flows the spacer sleeve 32 around and Return port 23 can get.

The flow connection 22 , the direct line 33 and the lower connection fitting 12 of the valve assembly 11 are formed as in the embodiment of FIGS. 1 and 2. A further explanation is therefore unnecessary.

In the embodiment of FIG. 9, a valve radiator 1 c is provided with two heating panels 2 b, 2 c arranged next to one another at a distance. The Vorlaufan circuit 22 , the direct line 33 and the lower connection fitting 12 of the valve assembly 11 are formed as in the imple mentation forms of FIGS . 1 to 4 and 8. There is no need for further explanations.

The return port 23 b, however, is now composed of a spherical housing 25 b with two diametrical cylindrical connecting pieces 27 b. In an extension of the connecting piece 27 b in the lower water channels 5 b, 5 c of the heating panels 2 b, 2 c spacers 38 with holes 39 are used, which serve to transfer the heating water from the lower water channels 5 b, 5 c into the return connection 23 b and enable the use of the pressure welding process for the determination of the return connection 23 b as an abutment.

In the embodiment of FIG. 9, therefore, the heating water flows from the heating water supply 30 via the before run connection 22 and the direct line 33 in the lower water channel 5 b of the heating panel 2 b to the lower connection armature 12 of the valve assembly 11 . From here, the heating water passes through the riser 13 to the upper connection fitting, not shown in more detail, which distributes the heating water to both heating panels 2 b, 2 c when the thermostatic valve is open. The heating water then passes from the heating panels 2 b, 2 c via the lower water channels 5 b, 5 c and the return connection 23 b to the heating water return 31 .

The embodiment of FIG. 10 corresponds largely to that of Fig. 9. However, it is now the pre overflow port 22 a and the lower connecting fitting 12 a of the valve set 11a according to the embodiment of FIGS. 6 through diametrically opposed connection pieces 26, 26 a or 18 , 18 a inserted between the sheets 4 , 4 a of both heating panels 2 b, 2 c. For this purpose, spacer sleeves 38 with holes 39 are then provided in the lower water channel 5 c, which, on the one hand, permit the use of the pressure welding process as an abutment to fix the flow connection 22 a and the lower connection fitting 12 a, and also return the heating water to the return connection 23 b to ensure. This corresponds to the design of FIG. 9.

Fig. 11 shows a direct line 33 b for transferring the heating water from a flow connection, for. B. 22 , to the lower connection fitting 12 of a valve set 11 in the form of a square tube. This is closed at the front. It has at the ends 34 a, 35 a side recesses 40 through which the heating water can flow. In addition, the ends 34 a, 35 a of the direct line 33 b are designed so that they are tight in the lower water channel, for. B. 5 , a heating panel, e.g. B. 2 , can be welded. When using a direct line 33 b according to FIG. 11 can then on spacers for the flow connection, for. B. 22 , and the lower connection fitting, for. B. 12 can be dispensed with.

In the context of Fig. 12 to 14 the embodiment of a valve radiator 1 d with a heating panel 2 d veran illustrates, in which a length section of the lower water passage 5 d as a direct line 33 c formed between the pre spill port 22 and the lower connecting fitting 12 of the valve trim 11 is. For this purpose, this direct line 33 c is closed both on the circumferential side and on the end side.

Furthermore, in this embodiment, care is taken that the vertical water channels 7 a in the height range between the upper horizontal water channel 6 a and the lower horizontal water channel 5 d are connected to one another several times via horizontal branch channels 41 . In this way, the heating water can flow with the thermostat valve 15 open from the area above the section of the lower water channel 5 d formed as a direct line 33 c transversely into the area on the other side of the vertical central transverse plane MQE and from here then into the lower one Water channel 5 d and from the sem get into the return port 23 . Otherwise, the embodiment of FIGS . 12 to 14 corresponds to that of FIG. 8, so that a further explanation is omitted.

The illustrated exporting in FIGS. 15 and 16 approximate shape of a valve radiator 1 e with a heating panel 2 e sees a formed in the heating panel 2 e, circumference side and closed-end channel as Direktlei tung 33 d between the supply header 22 and the lower connecting fitting 12 of a valve trim 11 before. The Di rektleitung 33 d can extend over the entire length of the heating panel 2 e. However, it is below the lower water channel 5 e, so that now the Rücklaufan circuit 23 c must have a longer connection sleeve 29 b for connec tion with the heating water return 31 .

Otherwise, the embodiment of FIGS. 15 and 16 corresponds to that of FIG. 8, so that a further explanation can be omitted here.
