Definitions

  • the invention relates to electric towel warmer radiators heat transfer fluid.
  • the invention aims to reduce the sealing defects on the plugs used to close the radiator electric towel warmers.
  • Electric towel warmer radiators have existed for about twenty years. These radiators consist of an assembly of tubular elements comprising collectors and heating tubes on which it is possible to put towels for their heating and / or drying. Inside the tubular elements of these radiators circulates a heat transfer fluid in a closed circuit. Some ends of the tubular elements are equipped with screw caps which are used for their closure.
  • screw caps have a head.
  • Each cap is screwed on a tapping formed in the inner wall of the tubular element of the towel rail radiator.
  • the seal is provided by a seal, which is crushed between the head of the screw and the tapping of the tube.
  • No specific housing is provided for the seal, which is housed in part in the tapping and overflowing, more or less, under the head of the screw, in particular depending on the importance of tightening the cap.
  • This embodiment traditionally used for twenty years, causes leaks and requires careful assembly, to limit the risk of leakage of the heat transfer fluid.
  • the tightening of the seal may change, sealing defects may also appear over time.
  • This type of leakage can occur at any open end of the collectors of the towel rail, and regardless of the type of screw element (cap, immersion heater, or other).
  • the object of the present invention is to overcome the disadvantages of the present devices for closing the open ends of tubular elements of electric heated towel rail radiators, in particular to propose a new type of mounting for the screw plugs used to seal said tubular elements.
  • Another object of the invention is to improve the sealing of shut-off devices, of the stopper type, of the open ends of said tubular elements, by allowing the standardization of shutter devices, irrespective of the size of the seals used. artwork.
  • an electric towel warmer radiator comprising tubular elements, such as heating tube (s) and collector (s), at least one of its ends is closed by at least one of the tubular elements by a screw cap engaging in a tapping formed mainly in the internal wall of said tubular element, the seal being provided by a joint arranged between the tapping and the screw head of the plug, the radiator being characterized in that an annular groove is formed in the inner wall of said tubular element at the end of the tapping, and is intended to receive an O-ring which at rest , has a thickness greater than the depth of said groove, and under stress is housed entirely within the groove allowing the screw head of the cap to abut on the end face of said tubular element.
  • tubular elements such as heating tube (s) and collector (s)
  • a screw cap engaging in a tapping formed mainly in the internal wall of said tubular element
  • the seal being provided by a joint arranged between the tapping and the screw head of the plug
  • the radiator being characterized in that an annular groove is formed in the inner wall of said
  • the seal ensures an excellent seal, with easy assembly.
  • the seal is properly positioned in its specific housing, in which it is only partially crushed by the head of the screw during the screwing of the cap, which increases its life.
  • the tightening of the plug is each time identical since the head of the screw of said plug abuts, so in direct support, on the end face of the tubular member of the towel rail radiator, the force of crushing of the seal is thus independent of the clamping force of the plug.
  • the annular groove is formed entirely in the inner wall of said tubular element, the entire face of the screw head of the plug, facing the end face of the tubular element. applying on said end face of the tubular element.
  • the manufacture of the cap can thus be standardized, since the screw head can be arbitrary, and this whatever the size of the seal used.
  • the annular groove is formed mainly in the inner wall of said tubular element, and partly in an annular zone of the face of the screw head of the cap, turned towards the face. end of the tubular element.
  • This part of the groove formed partially in the complementary annular zone of the face of the screw head of the plug corresponds to a recess of shallow depth, relative to the depth of the part of the groove formed mainly in the inner wall of the tubular element.
  • the section of the annular groove is substantially rectangular in shape.
  • the section of the groove may have at least one side (axial or radial), of rounded shape.
  • the annular groove thus maintains the entire seal in the annular groove, which forms its housing, without leaving the latter during crushing.
  • the seal is preferably a rubber O-ring.
  • the figure 1 is an elevational view of an electric towel rail radiator according to the present invention, comprising a screw cap.
  • the figure 2 is a sectional view showing the mounting of the screw cap of the radiator of the figure 1 according to a first embodiment of the invention.
  • the figure 3 is a sectional view showing the mounting of the screw cap of the radiator of the figure 1 according to a second embodiment of the invention.
  • the towel radiator 1 presented on the figure 1 is composed of tubular elements consisting of a manifold for the hot coolant 2, a manifold for the cold coolant 3 substantially vertical, to which are connected a plurality of horizontal heating tubes 4.
  • the coolant is heated by a resistor heating 5 connected to a power supply 6, and circulates in all of the heating tubes 4.
  • Screw plugs 7, not shown, can also be provided to close, for example, the top of the two collectors 2, 3.
  • the Figures 2 and 3 are in section the mounting of the screw cap 7.
  • the body 10 of the screw cap 7 is intended to engage and screw into a tapping 11 formed in the inner wall of said manifold 3.
  • annular groove 9 in the form of a shoulder, is formed completely in the inner wall of said manifold 3, at the open end of the tapping 11.
  • the annular groove 9 is partially (predominantly) formed in the inner wall of the collector 3, and partially (in the minor part) in the face of the plug facing the end of the collector 3.
  • the depth of the portion of the throat in the plug is small compared to the depth of the portion of the groove in the collector.
  • An O-ring 8 is housed in the annular groove 9: this seal has a thickness greater than the total depth of said groove 9, so as to exceed, at rest, said groove, therefore the end face 13 of the manifold 3 .
  • the seal 8 is never completely crushed, and always remains fully positioned in its specific housing that constitutes the annular groove 9.
  • the crushing force of the seal is independent of the clamping force of the screw cap 7.
  • the groove 9 has the shape of a ring, the section of which is substantially rectangular, and the seal is a rubber O-ring.
