Definitions

  • the invention relates to a radiator, in particular a tubular radiator, made of at least two identical basic elements, which are arranged laterally next to one another and are connected to one another in a liquid-tight and gas-tight manner at their hub-like head and foot region with the formation of a circular overflow opening by welding or in each case a nipple, one basic element having a connecting piece for the heating medium flow and another basic element is provided with a connecting piece for the heating medium return, at least the end-side basic elements in the head and foot area are provided with an internal thread for a sealing plug or a valve housing and the basic element provided with the connecting piece for the heating medium flow in this inlet area is sealed off from the adjacent base element and is provided in the other hub area with a seal for the valve housing.
  • Radiators of the type described above are known in various designs.
  • the basic element provided with the connecting piece for the heating medium supply is sealed in this inlet area from the neighboring basic element by the overflow opening through a metal disc is closed, which is welded into the overflow opening.
  • a separate welding process is therefore required for the closure, which not only means additional effort, but also is relatively difficult to carry out is because it must be carried out inside the preferably hub-like foot area.
  • the invention has for its object to reduce the technical effort for sealing the adjacent basic elements in the inlet area of the heating medium.
  • the solution to this problem by the invention is characterized in that the circular overflow opening between the base element provided with the connecting piece for the heating medium flow and the adjacent base element is closed by a washer which seals by means of a spacer by the sealing plug screwed into the opposite internal thread the edge surrounding the overflow opening is pressed.
  • This proposal according to the invention eliminates the additional welding process previously required for sealing adjacent basic elements in the inflow area of the heating medium. Instead of this welding process, a loose disc is inserted into the base element provided with the connecting piece for the heating medium flow during assembly of the radiator and pressed by means of the sealing plug, which is anyway necessary for closing the front opening, with the aid of a spacer to the edge surrounding the overflow opening to be closed in such a way that the basic elements welded together in the area of this overflow opening are sealed against one another. Since the sealing process only requires an additional spacer, but the welding of a pane that was previously required can be dispensed with, the technical effort is reduced to approximately 10% compared to the previously known construction.
  • valve housing to be inserted into the base element provided with the connecting piece for the heating medium flow must also be sealed with respect to the circular opening in the overflow area between this base element and the adjacent base element, it is proposed according to a further feature of the invention to carry out the sealing by means of a ring which is formed by an end collar of the valve housing is centered and pressed sealingly against the edge surrounding the overflow opening.
  • the embodiment according to the invention thus also results in a considerable reduction in the manufacturing outlay.
  • the disk or the ring consists of permanently elastic material, preferably of rubber or rubber-like plastic.
  • the spacer for fixing the disc is preferably designed as a tube.
  • the end collar of the valve housing is designed with a conical outer surface and an annular transition surface .
  • the conical surface provides reliable centering, the annular transition surface reliably presses the ring onto the edge of the overflow opening.
  • the invention further proposes that the basic element directly provided with the connecting piece for the heating medium flow with the connecting piece for to provide the heating medium return. This results in the same standard element for connecting the radiator to the heating medium lines, regardless of the number of basic elements of the radiator.
  • the heating power required for each individual case is determined by the number of additional basic elements.
  • the basic elements each consist of two head pieces and at least one connecting tube
  • valve housing is designed to receive the upper part of a thermostatic valve.
  • the connecting piece for the heating medium flow or heating medium return as a pipe piece provided with an internal thread and welded into the foot region of the respective basic element. This results in a particularly simple design for the connecting piece.
  • the radiator consists of a total of nine basic elements G1 to G9.
  • Every basic element G1 to G9 consists of two head pieces K1 and K2, each made, for example, of two half-shells and connected to one another by two connecting pipes V1 and V2.
  • Each basic element G1 to G9 has a hub-like head and foot region, in which two opposite circular overflow openings U are formed. In the edge region surrounding these overflow openings U, the basic elements G1 to G9 are connected to one another in a liquid-tight manner.
  • This connection of adjacent basic elements G1 to G9 takes place either by direct welding of the edges surrounding the overflow openings U or by welded-in threaded rings R which are connected to one another with the aid of a screw nipple N provided with an opposing thread.
  • the direct welding of adjacent basic elements G1 to G9 is shown in FIG. 3 by the weld seam S between the basic elements G1 and G2 and in FIG. 4 by the weld seam S between the basic elements G3 and G4.
  • the welding of the threaded rings R is shown with respect to the basic elements G2 and G3 both in FIG. 3 and in FIG. 4.
  • the first basic element G1 is provided in its hub-like foot region with a connecting piece A V , which is provided as an internally threaded pipe piece welded into the basic element G1 is trained.
  • the basic element G1 adjacent to this basic element G1 and connected to it by weld seams S in the area of the overflow openings U is provided in the foot area with a connector A R for the return of the heating medium.
  • the two basic elements G1 and G2 form a standard element for the connection of the respective radiator, regardless of how many further basic elements G3 to G9 are connected to the basic element G2.
  • the connection is - as can be seen in Fig.
  • Threaded rings R are also welded into the respective free overflow openings U of the base element G1 and the base element G9.
  • a sealing plug VS is screwed into each of these threaded rings R of the last basic element G9 and into the threaded ring R in the foot region of the basic element G1, the sealing plug VS being able to be provided with an opening in the head region of the basic element G9 for the use of a vent valve.
  • the circular overflow opening U in the foot area of these two basic elements G1 and G2 is closed by a disc 1, which by means of a spacer 2 through the in the threaded ring R screwed sealing plug VS is pressed sealingly against the edge surrounding the overflow opening U.
  • the disc 1 consists of permanently elastic material, preferably of rubber or rubber-like plastic. In this way, it forms a liquid-tight seal between the foot region of the two adjacent basic elements G1 and G2.
  • the spacer 2 is preferably designed as a tube.
  • a valve housing 3 is arranged in the head region of this basic element G1, which is shown in longitudinal section in FIG. 4 and is preferably used to hold a thermostatic valve.
  • This valve housing 3 is screwed into the head region of the base element G1 with the aid of the welded one Threaded ring R with the interposition of a seal D.
  • a collar 3a is formed, which forms a conical outer surface and a radially extending, annular transition surface.
  • the collar 3a engages in a ring 4 made of permanently elastic material, preferably rubber or rubber-like plastic, which in this way centers on the one hand and, on the other hand, seals against the edge of the overflow opening U which is connected to the base element G2 by a weld seam S.
  • Basic element G1 is pressed. This not only fixes the inner end of the valve housing 3, but also seals the valve housing 3 against the head region of the base element G1. It is thus ensured that the heating medium can only enter the head region of the base element G2 through the valve housing 3 from the head region of the base element G1.
  • a sealing of the basic elements G1 and G2 forming the standard element in the area of the connecting pieces A V and A R and a sealing of the valve housing 3 in the head area of the basic elements G1 and G2 is thus achieved, without using additional welding processes, by using the permanently elastic material disc 1 or the ring made of permanently elastic material 4, both parts assuming their position and performing their function by screwing in the sealing plug VS or the valve housing 3.
  • Whether and how many additional basic elements G3 to G9 are added to the standard element formed by basic elements G1 and G2 with the help of screw nipples N depends on the heating power required by the respective radiator.
