Definitions
- the invention relates to a coupling piece for small gas cylinders, which have a holding flange and a coaxial extraction valve and an external thread with a diameter D1 for fitting burners, which are equipped with an adjusting valve for the burner output, the coupling piece having a drilled threaded connection with one of the Have external threads of the small gas bottle complementary internal thread, a pierced pressure piece for opening the sampling valve and a clamping ring, which is divided into sectors that can be clamped against the retaining flange by means of a screw cap with a truncated cone surface.
- Couplings of this type are known; they are non-detachably connected to the respective burner, so that only burners can be used for the small gas bottles in question which have an internal thread within the coupling piece which matches the external thread of the small gas bottle.
- the burners in question are not with others Gas sources connectable, and the known small gas bottles can not be equipped with burners that have other coupling threads.
- the invention is therefore based on the object of specifying a coupling piece of the type described at the outset, which fits the standardized small gas cylinders and actuates their removal valve, but also enables the connection of the small gas cylinders to burners with a different design.
- the threaded connector has at its end facing away from the internal thread a pierced transition piece which carries an external thread with a diameter D2 which is larger than the diameter D1 of the external thread of the small gas bottle.
- Such a coupling piece enables the use of burners that are not exclusively intended for the known small gas cylinders, for example also for burners that do not necessarily have a metric thread. Couplings of this type, which can be produced cheaply as mass products, on the other hand enable the optional use of small gas cylinders which are not matched to one another.
- transition piece is connected to the threaded connector via a threaded connection, which is made non-detachable, for example by gluing. This makes production easier, and the transition piece and the threaded connector represent an inseparable unit.
- transition piece between the screw cap and its own external thread has a flange with a polygonal outer surface, which is used to attach a tool is provided.
- This polygon is preferably a hexagon for attaching a wrench. This allows the coupling piece to be tightly connected to the burner, with which it remains connected as long as the burner is to be used for the same small gas cylinders.
- the end of the transition piece facing away from the screw cap is designed as an annular surface for compressing a seal which lies between the burner and the transition piece.
- a burner 1 which has a handle part 2 and a burner tube 3, which is connected to the handle part via an adjusting valve 4.
- the burner works according to the so-called Bunsen principle, ie gas flows through a burner nozzle (not shown here) into the burner tube 3, to which ambient air is admixed by the injection effect of the gas jet via the suction openings 5.
- the adjustment valve 4 is adjustable via a knurled knob 6 and thus the so-called burner output.
- a pushbutton 7 is arranged laterally in the grip part 2 and actuates a main valve (not shown here) and a piezo igniter (also not shown).
- the main valve is closed as long as the push button is in the position shown.
- the pushbutton 7 By pressing the pushbutton 7, the main valve is opened and an ignition spark is transmitted to the burner tube 3, which ignites a flame when the adjusting valve 4 is open.
- the ignition spark is transmitted through a line which runs in a protective tube 8 and is connected to an electrode arranged in the burner tube 3.
- the push button 7 can be locked in the inserted state by pressing in a locking button 9 so that the main valve remains open.
- the locking button 9 is released and jumps out of the handle part 2 in a direction parallel to the burner tube 3.
- the pushbutton 7 then moves under spring force into the pushed-out position according to FIG. 1, as a result of which the main valve is closed and the burner flame goes out.
- the grip part At the end facing away from the burner tube 3, the grip part has an internal thread 10 with the diameter D2. The burner described above is state of the art and is therefore not further explained.
- the core of the invention is a coupling piece 11 which is screwed into the internal thread 10 and which connects the burner to a small gas bottle 12, which is also state of the art.
- the small gas bottle 12 has a holding flange 13 and a coaxial removal valve 14 which is surrounded by an external thread 15 which also belongs to the small gas bottle 12. This external thread has a diameter D1.
- the coupling piece 11 includes an axially pierced threaded connector 16 with an internal thread 17 which is complementary to the external thread 15 of the small gas bottle 12 and a pressure piece 18 which is also coaxially pierced therewith for opening the removal valve 14.
- the pressure piece 18 holds the removal valve 14 in the open position as long as that 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 cannot escape from the small gas bottle as long as the pushbutton 7 of the burner 1 is not actuated and the main valve is thereby opened.
- the coupling piece 11 has a clamping ring 19 known per se, which is divided into sectors 20 by a plurality of slots distributed equidistantly on the circumference, which can be clamped against the holding flange 13 by means of a screw cap 21.
- the screw cap 21 is provided with a truncated cone surface 21a which presses the sectors 20 against the holding flange 13. This radial pressing of the sectors 20 onto the holding flange 13 takes place by means of an axial movement component of the screw cap 21, which is indirectly connected to the threaded connector 16 via an actuating thread 22.
- This type of attachment or support of a burner with respect to a gas bottle is also known from the prior art specified at the outset.
- the threaded connector 16 is screwed at its end facing away from the internal thread 17 to a pierced transition piece 23 by means of a threaded connection 24, which is made non-detachable after assembly, for example by gluing.
- 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.
- a flange 25 with a polygonal outer surface 26 is arranged, which is used for attaching a tool in order to screw the coupling piece 11 firmly to the burner 1.
- the transition piece 23 is on its end 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 described in any more detail.
- a pierced pipe socket 29 In the center of the circular ring surface of the grip part 2 there is a pierced pipe socket 29 with a tapered extension 30 which engages in a complementary bore of the threaded socket 16.
- the entire coupling piece is rotationally symmetrical and that the various axial bores of the individual parts are connected in series, so that the fuel gas can flow out of the small gas bottle 12 as long as the coupling piece 11 is firmly connected to the small gas bottle 12 and the adjusting valve 4 and the main valve, not numbered, are open.
- Other seals that are made of elastomeric materials are not specified.
- the coupling piece 11 performs two functions: It can be connected to an equally standard burner 1, which is not designed for standardized small gas cylinders 12, for an unlimited period of time. However, its pressure piece 18 also extends the function of this burner 1, namely by causing the otherwise not possible opening of the extraction valve 14 of the small gas bottle 12.
