Definitions

  • the invention relates to a coupling piece for small gas cylinders, the one Holding flange and a coaxial extraction valve and an external thread having a diameter D1 for the placement of burners that are equipped with a control valve for the burner output, whereby the Coupling a drilled threaded connector with one to the External thread of the small gas bottle complementary internal thread pierced pressure piece for opening the sampling valve and one Have clamping ring, which is divided into sectors that by means of a Screw cap with a truncated cone surface against the retaining flange are braced.
  • Couplings of this type are known; they are insoluble with the respective Burner connected so that only for the small gas bottles in question Burners are usable within the coupling piece Have internal thread that to the external thread of the small gas bottle is appropriate.
  • the burners in question are not with others Gas sources connectable, and the known small gas bottles can not Burners that have different coupling threads.
  • EP 0 221 259 A1 discloses a complete gas burner with adjusting valve and ignition electronics using two different positive locking Fasteners either using each a connecting element with different connections different To connect liquefied gas cylinders or with simultaneous use both positive connection elements with two connections one and the same liquid gas bottle, the two corresponding complementary Has connection elements.
  • Such LPG bottles are as small gas bottles standardized in trade.
  • One connecting element of the gas burner consists of an internal fine thread, the other connecting element from an elastomer ring with spring tongues and from a clamping ring with a conical inner surface, which on the spring tongues acts.
  • the known clutch is neither intended for this nor suitable with complete gas burners of different origins and with different connection elements and dimensions to be connected.
  • the invention is therefore based on the object of a coupling piece Specify the genus described above, which to the standardized Small gas bottles fit and operate their extraction valve, but also the Connection of the small gas cylinders with differently equipped burners allows.
  • the solution to the problem is the one specified at the beginning Coupling piece according to the invention in that the threaded connector a pierced end facing away from the internal thread Has transition piece that has an external thread with a diameter D2 carries, which is larger than the diameter D1 of the external thread Small gas cylinder.
  • Such a coupling piece allows the use of burners that are not are intended exclusively for the known small gas cylinders, for example for burners that are not necessarily metric Have threads.
  • Such coupling pieces which are cheap as mass products are producible, allow the optional use of Small gas cylinders, on the other hand, which are not adapted to each other.
  • transition piece has a Threaded connection is connected to the threaded connector, which is unsolvable is made, for example by gluing. This will make it relieved, and the transition piece and the threaded connector provide one inseparable unit.
  • transition piece between the Screw cap and its own external thread with a flange has a polygonal outer surface for attaching a tool is provided.
  • This polygon is preferably a hexagon for that Apply a wrench. This allows the coupling piece tightly connected to the burner with which it is connected for as long remains as the burner can be used for the same small gas cylinders should.
  • a burner 1 is shown, the handle part 2 and a burner tube 3, which is connected to the handle part via an adjusting valve 4.
  • the Brenner works on the so-called Bunsen principle, i.e. through one here Not shown burner nozzle gas flows into the burner tube 3, through the Injection effect of the gas jet through the suction openings 5 ambient air is added.
  • the adjustment valve 4 is via a knurled knob 6 adjustable and thus the so-called burner output.
  • a push button 7 is arranged on the side, which is not one here shown main valve and a piezo igniter also not shown actuated. As long as the push button is in the drawn position, the main valve is closed. Pressing the pushbutton 7 will Main valve opened and an ignition spark transferred to burner tube 3, the a flame ignites when the adjusting valve 4 is open. The spark is transmitted through a line that runs in a protective tube 8 and on an electrode arranged in the burner tube 3 is connected.
  • the Push button 7 can be pushed in by pushing it in lock a locking button 9 so that the main valve remains open. When the push button 7 is pressed again, the locking button 9 released and jumps out of the handle part 2 in a direction parallel to Burner tube 3 out.
  • the pushbutton 7 then reaches the spring force in the pushed out position according to Figure 1, whereby the main valve is closed and the burner flame goes out.
  • the handle part On the burner tube 3 opposite end, the handle part has an internal thread 10 with the Diameter D2. The burner described above is state of the art and is therefore not explained further.
  • the essence of the invention is a coupling piece 11 which fits into the internal thread 10 is screwed in and that the burner with a small gas bottle 12th connects, which is also state of the art.
  • the small gas bottle 12 has a retaining flange 13 and a coaxial removal valve 14 which by an external thread 15 also belonging to the small gas bottle 12 is surrounded. This external thread has a diameter D1.
  • An axially drilled threaded connector 16 is part of the coupling piece 11 one complementary to the external thread 15 of the small gas bottle 12 Internal thread 17 and a coaxial likewise pierced pressure piece 18 for opening the sampling valve 14.
  • the pressure piece 18 holds it Removal valve 14 in the open position as long as the coupling piece 11 is connected to the small gas bottle 12. For this reason it will Appropriately leave the coupling piece on the burner 1 so that the fuel gas is out the small gas bottle cannot escape as long as the push button 7 of the Burner 1 is not actuated and the main valve is opened.
  • this has Coupling piece 11 a known clamping ring 19, which by a Plurality of equidistantly distributed slots in sectors 20 is divided, by means of a screw cap 21 against the holding flange 13 are braced.
  • the screw cap 21 with a Truncated cone surface 21a provided that the sectors 20 against the retaining flange 13 presses.
  • This radial pressing of the sectors 20 onto the holding flange 13 happens by an axial component of movement of the screw cap 21, indirectly via an actuating thread 22 with the threaded connector 16 connected is.
  • This type of attachment or support Brenners compared to a gas bottle is indicated by the above State of the art known.
  • the threaded connector 16 is on its end facing away from the internal thread 17 with a pierced Transition piece 23 screwed by means of a threaded connection 24, the is made insoluble after assembly, for example by Bonding.
  • the pierced transition piece 23 has an external thread 23a with a diameter D2 which is significantly larger than the diameter D1 of the external thread 15 of the small gas bottle 12.
  • the transition piece 23 is on to produce the necessary seal its face 27 facing the burner 1 as an annular surface formed on which a sealing ring 28 rests.
  • the handle part 2 of the burner 1 has a circular ring surface which is suitable for this and is not designated in any more detail.
  • the coupling piece 11 performs two functions: It can also be used with one commercially available burner 1, which is not for standardized small gas cylinders 12 trained to connect indefinitely. It can be expanded by Pressure piece 18 but also the function of this burner 1 by namely the otherwise not possible opening of the removal valve 14 of the Small gas bottle 12 brings about.
