Definitions

  • the invention relates, on the one hand, to a method for sealingly attaching a connection adapter having a housing with two lines to a radiator, one line with its connecting flange being connected to a connecting piece of the radiator flow and the other line to a connecting piece of the radiator return.
  • the invention also relates to the connection adapter itself, which is suitable for connecting a valve, in particular a thermostatic valve, or a pump to a radiator.
  • the invention relates to a radiator suitable for the connection of the adapter and the system of adapter and radiator.
  • Such two-pipe connections are mainly used in radiators, the sockets of flow and return opening in the lower area.
  • This type of connection is known, for example, from so-called towel radiators, which are installed in bathrooms as large radiators equipped with a large number of individual heating pipes.
  • the two-pipe connections of these radiators usually obey a certain standard.
  • the sockets have an internal thread of inches and are spaced 50 mm apart. Intermediate pieces are screwed into the threads, to which an adapter is screwed by means of union nuts.
  • the disadvantage of this known type of connections is that they are comparatively complex to assemble because of the large number of components required and that they require a large construction volume.
  • hemp, Teflon or special sealing bushes are used for the sealing of the pipe connections.
  • Clamping ring screw connections sealing over metal are also known.
  • the known seals seal the thread or the outer wall of the nested pipes. These seals are complex to assemble and tend to leak.
  • a disadvantage of the large construction volume is the disturbing aesthetic impression. So it is particularly important with towel radiators that they blend aesthetically into the ambience of the bathroom, whereby conspicuous connection components or protruding thermostatic valves negatively influence the sometimes complex design of these radiators.
  • the object of the present invention is now to create a method for the simple and safe mounting of a connection adapter.
  • Another object is to create a radiator that is particularly suitable for the use of such a connection adapter.
  • the main basic idea of the invention is to design an adapter so that it has two end connection flanges, in particular in one plane, which are then each pressed by means of a seal onto the end faces of the connecting pieces of the radiator serving as counterpart.
  • the necessary contact pressure is exerted by means of a fastener which easily accesses the housing and the radiator.
  • the solid housing of the adapter is now connected directly to the heater, the connections being tightly clamped between the adapter and the heater.
  • the seal is made via the end sealing surfaces, which can be of any design and are placed against one another by means of the seal. According to the power flow generated by the fastener passes through the entire housing and not only through the flanges of the Adapter. This provides a much more stable connection of adapters with a connected valve or pump.
  • the end faces of the connecting flanges are each placed on end faces of the connecting piece by means of a seal and the housing is releasably fastened to the radiator with a fastening means.
  • the fastening means acts on a part connected to the radiator in such a way that a force flow passes through the housing, which generates a contact pressure between the connection adapter and the radiator, this acting in particular symmetrically on the seals as a preload.
  • the symmetrical flow of force is particularly advantageous because it ensures uniform loading and sealing of the nozzle.
  • the type of mounting according to the invention has several advantages, which essentially result from the fact that the previously required union nuts can be dispensed with:
  • the mounting of the adapter is particularly simple and convenient, requiring only the actuation of one, in particular a single, fastening means in a particularly simple case, an externally accessible screw is required. This enables quick and safe installation.
  • the type of fastening offers the possibility of saving components, such as previously required intermediate pieces, and thus reducing costs on the one hand and installation space on the other.
  • the distance between the adapter and the radiator can be reduced by more than one centimeter by means of the invention.
  • the housing is fastened to the radiator with only a single fastening means, which engages on the side of the housing facing away from the connecting flanges, which is easily accessible to the fitter with tools.
  • the fastening means is a screw which extends through a bore in the housing and which acts on a thread located on the radiator.
  • connection adapter is advantageous, the at least two connection flanges of which face the radiator have sealing faces on the end face, each of which has a seal ah connecting piece Radiator be sealed.
  • a fastening means is provided which engages on the side of the housing facing away from the connecting flanges and which, in engagement with a holding means provided on the heating element, generates a force acting axially to the connecting flanges.
  • the fastening means acting on the side facing away from the connecting flanges in turn generates the power flow running through the housing.
  • Such an adapter can be used to connect any fittings, and it is particularly advantageous to connect a valve, such as a thermostatic valve or a pump, to it.
  • the adapter can also serve as a simple connection piece to the pipelines of the flow and return. It could also be designed as a blind plug or bypass line. To connect the elements mentioned and to connect the heating pipes, the adapter naturally has corresponding connection options of the known type.
  • the adapter is advantageously made of metal or plastic.
  • the adapter can be designed to be particularly compact if the sealing surfaces of the connecting flanges are introduced, in particular screwed, into the housing.
  • the sealing surfaces inside the housing surround the mouths of the cables running in the housing and are particularly well protected against possible damage during assembly due to their recessed position.
  • seals with a correspondingly large sealing ring can be provided, which can be inserted into the flanges designed as recesses. These can be pre-assembled by simply plugging them into the adapter and protecting the sealing surfaces with their presence.
  • the sealing surfaces of the flanges thus form receptacles for inserting the seals. It is particularly advantageous if the sealing surfaces lie in a single common plane, so that a simple sealing on the end surfaces of the radiator connecting pieces, which are usually in a common plane, is possible.
  • a particularly simple assembly is ensured if a simple screw is provided as the fastening means, the head of which, in particular as a hexagon socket, is accessible from the side of the housing facing away from the connecting flanges and extends through a hole made in the housing.
  • the adapter can thus be assembled and disassembled in a single operation.
  • the counterpart matching the screw, in particular the internal thread is advantageously attached directly to the radiator.
  • a carrier plate is provided for this purpose with an internal thread that is welded as connection 'between the neck of the radiator. With such a sheet fastened by spot welding, existing radiators can also be retrofitted.
  • the geometry of the connecting pieces is usually standardized, so that only one type of mounting plate has to be provided for all types of radiators.
  • a radiator equipped with such a non-releasably attached holding means is particularly suitable for connecting the connection adapter according to the invention. Retaining means and fasteners are designed so that they can be easily and conveniently brought into mutual engagement.
  • the bore provided for the fastening means, in particular for the screw parallel to the axes of the connection flanges and in the plane formed by the axes.
  • the hole runs centrally between the axes.
  • the fastening means in particular the screw
  • the holding means at least to such an extent that the sealing surfaces of the connection adapter can be pressed securely onto the connecting piece of the radiator.
  • a through hole is therefore proposed in particular for the internal thread of the holding means.
  • an internal thread in a blind hole it is important to ensure that the screw can be screwed sufficiently deep into the internal thread.
  • FIG. 1 a towel radiator with adapter and thermostatic valve
  • FIG. 2 shows a connection adapter from a front view
  • connection adapter 3 shows a connection adapter from the rear view
  • Figure 4 six ways of sealing with a sealing ring.
  • FIG. 1 shows a known towel radiator 1 from the rear facing the wall, with its two vertical manifolds 2 and its horizontally arranged heating tubes 3.
  • a connection adapter 5 is attached on the bottom heating tube 4, which has an internal separation.
  • the connection adapter 5 Via the connection adapter 5, the supply and return lines (not shown) emerging from the wall of the heating system are connected via connection piece 6.
  • a thermostatic valve 7 is connected by means of the housing of the adapter 5.
  • the detailed drawing in Figure 1 shows the adapter 5 in an enlarged view.
  • the nozzles 6 in this case have a standardized distance of 50 mm and are in a plane perpendicular to the wall.
  • the lines are deflected knee-shaped by 90 ° from the level of the radiator to the wall.
  • the thermostatic valve 7 is attached laterally via a separate connection and is integrated into the return line of the adapter.
  • connection adapter In the rear view of the connection adapter according to Figure 2, the individual parts are shown in an exploded view.
  • the compact housing 8 can be seen with two connecting flanges 9, which are provided for connection to corresponding connecting pieces 10 of the radiator 1.
  • the connecting flanges 9 have sealing surfaces 11 screwed into the housing, which surround the mouths 12 of the lines running in the housing. Flow and return line of the heating system are connected as described, via the nozzle 6. In this case, a thermostatic valve 7 is introduced in the return.
  • the sealing surfaces 11 form receptacles which are suitable for inserting seals 13 ' .
  • the seals 13 are made of rubber or a soft plastic and have a sealing disk covering the sealing surfaces 11.
  • the sealing washers on the other hand, rest on the end face of the connecting piece 10 and reach into it with a cylindrical approach. For a better hold in the socket 10, the cylindrical approaches are surrounded with retaining beads.
  • a screw 14 is provided as the fastening means, which extends through a bore 15 made in the housing 8 and whose head is accessible from the side of the housing 8 facing away from the connecting flanges 9.
  • the bore 15 is parallel to the axes of the connecting flanges 9 and lies in the plane formed by the axes.
  • the bore 15 runs centrally between the axes in order to distribute the force evenly over both connecting flanges 9.
  • the screw 14 can be screwed into an internal thread 16 located on the heating element 1, which is introduced into a connecting piece 17 connecting the connecting piece 10a of the flow to the connecting piece 10b of the return.
  • the connecting piece 17 is inserted centrally between the connecting pieces by spot welding.
  • connection adapter is shown again from the rear.
  • a cover 18 is also shown, which is clamped onto the socket 10 after the adapter has been installed and which contributes to a harmonious design of the radiator and connection adapter system.
  • FIG 4 three methods of sealing are shown, in each of which an O-ring 19 is provided between the connector 10 and the housing 8.
  • a groove 20 is screwed into the sealing surface 11, in which the O-ring 19 lies.
  • the mouth 12 is surrounded by a cone, on which the internal thread of the socket strikes.
  • the connecting pieces 10 are usually painted with lacquer, it is advantageous to provide the seal as in Example 4b where there is no lacquer, namely, for example, in the inner diameter of the connecting piece 10. This prevents the O-ring from being connected to a painted area and leaks can occur if the paint expands when it is heated.
  • FIG. 4c shows an exemplary embodiment in which a groove is screwed radially into the inner wall of the housing surrounding the sealing surface 11.
  • Figures 4d to 4f show other methods of sealing.
  • a further part to be screwed into the socket 10, for example by means of a teflon seal, this part then sealingly sealing against the housing 8.
  • the fastening screw 14 is screwed directly into the radiator 1, a plug with thread being welded into the pipe 4 between the connecting pieces 10 a and 10 b of the radiator 1, into which the fastening screw 14 is screwed.
