Description

Die Erfindung bezieht sich auf einen Brennergriff mit Ventileinrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a burner handle with valve device according to the preamble of claim 1.

Bei derartigen bekannten Brennergriffen (Sievert Flüssiggas-Geräte, Juni 1973, Modell Sievert 3487) ist am hinteren Ende eine Schlauchverschraubung zum Anschluß eines Gaszuführungsschlauches und am vorderen Ende eine Rohrverschraubung zum Anschluß eines Verbindungsrohres zum Brennerkopf vorgesehen. Am vorderen Ende des Brennergriffs sind zwei Spindelventile angeordnet, die als Absperr- und Regelventil ausgebildet sind und von denen das eine zur Einstellung der Hauptflamme und das andere zur Einstellung einer Sparflamme dienen. Es ist ferner ein unter Federdruck stehender Schieberkolben vorgesehen, der mit einem Schnellschalthebel betätigt werden kann um das Sparflammenventil zu überbrücken. Nachteilig bei diesem Brennergriff ist der Umstand, daß das Absperr- und Regelventil für die Hauptflamme in gleicher Weise ausgebildet ist wie für die Sparflamme. Die Bedienungsperson kann demnach das Regelventil für die Sparflamme so verändern, daß von einem Spareffekt nicht mehr gesprochen werden kann. Ebenso entfällt dadurch die notwendige Sicherheit, weil von der Berufsgenossenschaft eine bestimmte Länge der Sparflamme vorgeschrieben ist.In such known burner handles (Sievert LPG devices, June 1973, model Sievert 3487), a hose screw connection for connecting a gas supply hose and a pipe screw connection for connecting a connecting pipe to the burner head are provided at the rear end. At the front end of the burner handle, two spindle valves are arranged, which are designed as shut-off and control valves and one of which is used to set the main flame and the other to set an economy flame. There is also a spool under spring pressure, which can be operated with a quick-release lever in order to bypass the pilot light valve. A disadvantage of this burner handle is the fact that the shut-off and control valve for the main flame is designed in the same way as for the low flame. The operator can therefore change the control valve for the flame so that it can no longer be spoken of a saving effect. This also eliminates the necessary security, because a certain length of the flame is prescribed by the trade association.

Der Erfindung liegt die Aufgabe zugrunde, einen Brennergriff mit Ventileinrichtung zu schaffen, bei der das Sparflamme-Einstellventil voreingestellt werden kann, ohne daß eine unkundige Bedienungsperson diese voreinstellung veränden könnte.The invention has for its object to provide a burner handle with a valve device in which the flame control valve can be preset without an unfamiliar operator could change this preset.

Die Lösung dieser Aufgabe gelingt aufgrund der Maßnahme des Hauptanspruchs. Die Unteransprüche beziehen sich auf Ausgestaltungen und Weiterbildungen der Erfindung.This task is solved on the basis of the measure of the main claim. The subclaims relate to refinements and developments of the invention.

Indem das Absperr- und Regelventil näher zur Griffschale und das Sparflamme-Einstellventil mit Schieberkolben näher zum Verbindungsrohr des Brennerkopfes angeordnet ist, unterliegen das Sparflamme-Einstellventil und der Schieberkolben weniger hohen Drücken. Die Anordnung des Sparflamme-Einstellventils innerhalb einer Achsialbohrung des Schieberkolbens ist nicht nur raumsparend, sondern auch für Laien nicht erkennbar. Während Fachkundige auf diese Weise den Brenner richtig einstellen und bei Verstopfungen durch kurzes Durchblasen reinigen können, ist das Sparflamme-Einstellventil für Unbefugte nicht erkennbar zugänglich.By placing the shut-off and control valve closer to the handle and the flame control valve with slide piston closer to the connecting tube of the burner head, the flame control valve and the slide piston are subject to less high pressures. The arrangement of the flame control valve within an axial bore of the spool is not only space-saving, but also not recognizable to laypersons. While experts can correctly set the burner in this way and clean them with a short blow if there is a blockage, the flame control valve is not visibly accessible to unauthorized persons.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung beschrieben. Es zeigt

  • Fig. 1 einen Längsschnitt durch das vordere Ende eines Brennergriffs,
  • Fig. 2 einen Längsschnitt um 90 Grad gedreht und
  • Fig. 3 eine Seitenansicht des Brennergriffs.
An embodiment of the invention is described with reference to the drawing. It shows
  • 1 shows a longitudinal section through the front end of a burner handle,
  • Fig. 2 rotated a longitudinal section through 90 degrees and
  • Fig. 3 is a side view of the burner handle.

Der abgebrochen dargestellte Brennergriff 1 enthält ein Zuführungsrohr 2, eine Griffschale 3 und ein Ventilgehäuse 4. Das Ventilgehäuse 4 besitzt ein Innengewinde 5 für das Zuführungsrohr 2 und ein Außengewinde 6 für ein nicht dargestelltes Verbindungsrohr zum Brennerkopf. Das Zuführungsrohr 2 stellt die Gas-i Zuführöffnung 46 und der Kanal 13 mit dem Innenkonus 7 die Gas-Abführöffnung 47 des Brenngases dar. Die Zuführöffnung 46 führt in den Übergangskanal 8, der durch ein Absperrund Regelventil 9 mehr oder weniger weit geöffnet werden kann und führt über einen Verbindungskanal 10 in eine Querbohrung 11 des Ventilgehäuses 4. Die Querbohrung 11 ist über einen achsial verlaufenden Kanal 13 und anschließendem Innenkonus 7 mit der Gas-Abführöffnung 47 verbunden.The burner handle 1 shown broken off contains a feed tube 2, a grip shell 3 and a valve housing 4. The valve housing 4 has an internal thread 5 for the feed tube 2 and an external thread 6 for a connecting tube (not shown) to the burner head. The supply pipe 2 represents the gas i supply opening 46 and the channel 13 with the inner cone 7 represents the gas discharge opening 47 of the fuel gas. The supply opening 46 leads into the transition channel 8, which can be opened to a greater or lesser extent by a shut-off and control valve 9 leads via a connecting channel 10 into a transverse bore 11 of the valve housing 4. The transverse bore 11 is connected to the gas discharge opening 47 via an axially extending channel 13 and subsequent inner cone 7.

Innerhalb der Querbohrung 11 ist ein Schieberkolben 14 angeordnet, der mit einem Kopf 15 nach außen ragt und an diesem Ende über Dichtungen 16 abgedichtet wird. Das andere Ende der Querbohrung 11 ist über weitere Dichtungen 17 und 18 und über die Verschlußschraube 19 abgedichtet, die als Sitz einer Rückholfeder 20 ausgebildet ist. Am Schieberkolben 14 ist eine Ringdichtung 21 vorgesehen, und zwar im Bereich einer Konusfläche 12 der Querbohrung 11. Die Rückholfeder 20 drängt den Schieberkolben 14 mit seiner Ringdichtung 21 gegen die Konusfläche 12 und wird dabei von dem jeweiligen Gasdruck in der unteren Gaskammer 22 unterstützt. Die Querbohrung 11 wird durch die Ringdichtung 21 in zwei Gaskammern 22 und 23 unterteilt. Die Gaskammer 22 steht über den Verbindungskanal 10 und den Übergangskanal 8 mit der Gas-Zuführöffnung 46 in Verbindung.Arranged within the transverse bore 11 is a slide piston 14 which projects outwards with a head 15 and is sealed at this end by means of seals 16. The other end of the transverse bore 11 is sealed by further seals 17 and 18 and by the screw plug 19, which is designed as the seat of a return spring 20. An annular seal 21 is provided on the slide piston 14, specifically in the region of a conical surface 12 of the transverse bore 11. The return spring 20 presses the slide piston 14 with its annular seal 21 against the conical surface 12 and is supported by the respective gas pressure in the lower gas chamber 22. The transverse bore 11 is divided into two gas chambers 22 and 23 by the ring seal 21. The gas chamber 22 is connected to the gas supply opening 46 via the connecting duct 10 and the transition duct 8.

Das Ventilgehäuse 4 weist ein Lagerauge 24 auf, an welchem ein Schnellschalthebel 25 schwenkbar befestigt ist, der an dem Kopf 15 des Schieberkolbens 14 einerseits und andererseits an dem Anschlagnocken 40 am Lagerauge 24 anliegt. Dabei muß der Schnellschalthebel 25 aus Sicherheitsgründen den Spielraum 41 behalten. Wenn der Schnellschalthebel 25 betätigt wird, wird der Schieberkolben 14 entgegen der Kraft der Rückholfeder 20 und entgegen dem jeweiligen Gasdruck in der Gaskammer 22 verschoben, und die Ringdichtung 21 kommt von der konischen Fläche 12 frei, so daß ein Ringspalt die Gaskammer 22 mit der Gaskammer 23 verbindet. Der Ringspalt ist genügend groß, so daß der Gasstrom im wesentlichen durch die Einstellung am Absperr- und Regelventil 9 bestimmt wird.The valve housing 4 has a bearing eye 24, to which a quick-release lever 25 is pivotally attached, which rests on the head 15 of the slide piston 14 on the one hand and on the other hand on the stop cam 40 on the bearing eye 24. The quick-release lever 25 must keep the scope 41 for safety reasons. When the quick-release lever 25 is actuated, the slide piston 14 is displaced against the force of the return spring 20 and against the respective gas pressure in the gas chamber 22, and the ring seal 21 comes free from the conical surface 12, so that an annular gap separates the gas chamber 22 with the gas chamber 23 connects. The annular gap is sufficiently large that the gas flow is essentially determined by the setting on the shut-off and control valve 9.

Das Absperr- und Regelventil 9 besteht im wesentlichen aus einer Schraubspindel 26, die durch einen Drehknopf 27 gedreht werden kann und ein konusförmiges Ende 28 besitzt, welches mit einem entsprechenden Ventilsitz 43 im Ventilgehäuse 4 zusammen arbeitet. Auf diese Weise kann der Zustrom von Gas vom Übergangskanal 8 in den Verbindungskanal 10 gesperrt werden, oder es kann ein Drosselspalt freigehalten werden, der die Größe der Hauptflamme bestimmt.The shut-off and control valve 9 consists essentially of a screw spindle 26 which can be rotated by a rotary knob 27 and has a conical end 28 which works together with a corresponding valve seat 43 in the valve housing 4. In this way, the inflow of gas from the transition channel 8 into the connecting channel 10 can be blocked, or a throttle gap can be kept free, which determines the size of the main flame.

In achsialer Richtung des Schieberkolbens 14 ist eine Stufenbohrung 29 vorgesehen, die an einer Querbohrung 30 endet. Die Querbohrung 30 mündet in die obere Gaskammer 23 und steht damit mit dem Auslaufkanal 13 in Verbindung. Innerhalb der Stufenbohrung 29 ist ein Sparflamme-Einstellventil 31 untergebracht, welches als eine Schraubspindel ausgebildet ist und als solche einen mit Querschlitz versehenen Zylinderkopf 32, einen Gewindeteil 33 und einen Ventilkonus 34 besitzt. Der Gewindeteil 33 arbeitet mit einem entsprechenden Gewindeteil der Stufenbohrung 29 zusammen, so daß der Ventilkonus 34 mehr oder weniger weit in Richtung auf einen Ventilsitz verschoben werden kann. Wenn ein Ringspalt freibleibt, so stellt dieser eine Drosselstelle dar, welche den Gasstrom einzustellen ermöglicht, der aus der unteren Gaskammer 22 über eine Querbohrung 35 in eine Kammer 29 gelangt. Die Kammer 29 grenzt an den Ventilkonus 34, der die Öffnungsweite des Sparflamme-Einstellventils 31 an der Drosselstelle bestimmt.In the axial direction of the slide piston 14, a stepped bore 29 is provided, which ends at a transverse bore 30. The transverse bore 30 opens into the upper gas chamber 23 and is thus connected to the outlet channel 13. Within the stepped bore 29 there is accommodated a low-flame setting valve 31 which is designed as a screw spindle and as such has a cylinder head 32 provided with a transverse slot, a threaded part 33 and a valve cone 34. The threaded part 33 cooperates with a corresponding threaded part of the stepped bore 29 so that the valve cone 34 can be displaced more or less towards a valve seat. If an annular gap remains free, this represents a throttle point which enables the gas flow to be set, which flows from the lower gas chamber 22 via a transverse bore 35 into a chamber 29. The chamber 29 adjoins the valve cone 34, which determines the opening width of the flame-setting valve 31 at the throttle point.

Da das Sparflamme-Einstellventil 31 durch Drehen mit einem Schraubenzieher eingestellt wird, muß der Schieberkolben 14 gegen Drehung gesichert sein. Das vordere Ende 42 am Schieberkolben 14 ist deshalb als Vierkantkopf ausgebildet und wirkt mit entsprechenden Vierkantflächen im Ventilgehäuse 4 zusammen. Das Einstellventil 31 sollte schwergängig sein, damit es sich nicht verstellt. In diesem Sinne wirken bereits die Dichtungen 17, welche die untere Gaskammer 22 nach außen abdichten oder ein Dichtungsmaterial, welches auf den Gewindeteil 33 von dem Sparflamme-Einstellventil 31 aufgebracht wird. Als weitere Hemmung kann eine Druckfeder 37 zwischen einem Ansatz oder Flansch des Sparflamme-Einstellventils 31 und einer Stirnfläche des Schieberkolbens 14 gefügt sein, wodurch die beiderseitigen Gewinde 33 gegeneinander verspannt werden.Since the flame control valve 31 is set by turning with a screwdriver, the spool 14 must be secured against rotation. The front end 42 on the spool 14 is therefore designed as a square head and interacts with corresponding square surfaces in the valve housing 4. The adjustment valve 31 should be stiff so that it does not move. The seals 17, which seal the lower gas chamber 22 to the outside, or a sealing material which is applied to the threaded part 33 by the low-flame setting valve 31 already act in this sense. As a further inhibition, a compression spring 37 can be fitted between a shoulder or flange of the flame-setting valve 31 and an end face of the slide piston 14, as a result of which the threads 33 on both sides are braced against one another.

Der Kopf der Verschlußschraube 19 weist eine Aussparung zur Aufnahme einer Verschlußkappe 38 aus Messing oder durchsichtigem Kunststoff auf, um den Zugang zum Sparflamme-Einstellventil 31 abzudecken. Die Verschlußkap-pe 38 muß mit einer Luftausgleichsbohrung 39 für die Be- und Entlüftung bei der Bewegung vom Schieberkolben 14 versehen sein.The head of the locking screw 19 has a recess for receiving a locking cap 38 made of brass or transparent plastic in order to cover the access to the pilot light setting valve 31. The breech cap 38 must be provided with an air compensation bore 39 for ventilation when moving the slide piston 14.

Die Handhabung des Brennergriffs 1 geht wie folgt vor sich:

  • Bei aufgedrehtem Absperr- und Regelventil 9 wird das Sparflamme-Einstellventil 31 fabrikmäßig so eingestellt, daß die Sparflamme ihre vorgeschriebene Länge einnimmt. Durch Verschließen mit der Verschlußkappe 38 wird die Verstellung des Sparflamme-Einstellventils 31 Unbefugten erschwert. Im Betrieb stellt man sich die Hauptflamme mit dem Absperr- und Regelventil 9 ein und kann diese durch Betätigung des Schnellschalthebels 25 über den Schieberkolben 14 ein- und ausschalten.
The torch handle 1 is handled as follows:
  • When the shut-off and control valve 9 is turned on, the flame control valve 31 is set in the factory so that the flame reaches its prescribed length. Closing with the closure cap 38 makes it difficult for unauthorized persons to adjust the flame control valve 31. In operation, the main flame is set with the shut-off and control valve 9 and can be switched on and off by actuating the quick-release lever 25 via the slide piston 14.

Durch Verschmutzungen kann es vorkommen, daß sich der Ringspalt am Ventilkonus 34 vom Sparflamme-Einstellventil 31 ganz oder teilweise zusetzt. Der Fachkundige kann daraufhin die Verschlußkappe 38 abnehmen und durch Öffnen des Sparflamme-Einstellventils 31 den Ringspalt so stark vergrößern, daß nach dem Öffnen vom Regel- und Absperrventil 9 der Düsendurchgang von dem durchströmenden Gas gesäubert wird. Danach wird die Sparflamme neu eingestellt.Dirt can cause the annular gap on valve cone 34 to become clogged in whole or in part by low-flame setting valve 31. The person skilled in the art can then remove the closure cap 38 and enlarge the annular gap by opening the pilot flame adjustment valve 31 to such an extent that after opening the control and shut-off valve 9 the nozzle passage is cleaned of the gas flowing through it. Then the flame is reset.

Handbrenner gibt es in unterschiedlichen Baugrößen. Wegen der weiten Verstellbarkeit des Sparflämme-Einstellventils 31 ist es jedoch möglich, für alle Baugrößen ein und dasselbe Sparflamme-Einstellventil 31 zu verwenden.Hand torches are available in different sizes. Because of the wide adjustability of the flame control valve 31, however, it is possible to use the same flame control valve 31 for all sizes.

Der lange Schnellschalthebel 25 (Fig. 3) sollte nicht auf der Griffschale 3 aufliegen. Dabei könnten leicht Hautfalten eingeklemmt werden. Deshalb ist das Gehäuse 4 so verandert worden, daß durch die geschaffene Auflagefläche 52 für den Schnellschalthebel 25 ein genügend großer Abstand 49 zwischen Griffschale 3 und Schnellschalthebel 25 entsteht. Gleichzeitig wird beiderseits am Gehäuse 4 eine Führungsfläche 50 für den Schnellschalthebel 25 in der oberen Stellung, zusätzlich zu der Führungsfläche 51 in der unteren Stellung gebildet, die wesentlich zu der notwendigen Stabilität im rauhen Baustellenbetrieb beitragen, weil sich der lange Schnellschalthebel 25 nicht mehr seitlich verbiegen läßt.The long quick-release lever 25 (FIG. 3) should not rest on the grip 3. This could easily pinch skin folds. Therefore, the housing 4 has been changed so that a sufficiently large distance 49 between the handle shell 3 and quick-release lever 25 is created by the created bearing surface 52 for the quick-release lever 25. At the same time, a guide surface 50 for the quick-release lever 25 in the upper position is formed on both sides of the housing 4, in addition to the guide surface 51 in the lower position, which contribute significantly to the necessary stability in rough construction site operation because the long quick-release lever 25 no longer bends laterally leaves.

In der Fig. 3 ist die Griffschale 3 vollständig mit Schlauchverschraubung 55 und der Abstand 56 zwischen Griffschale 3 und Schnellschalthebel 25 in der oberen Stellung dargestellt. Der Abstand 56 wurde groß gewählt, damit man die Griffschale 3 bei abgeschalteter Hauptflamme besser umfassen kann.In Fig. 3, the grip shell 3 is shown completely with hose screw 55 and the distance 56 between the grip shell 3 and quick-release lever 25 in the upper position. The distance 56 was chosen to be large, so that one can better grip the grip shell 3 when the main flame is switched off.

Die Auflagefläche 52 begrenzt die Öffnungsbewegung fur den Schieberkolben 14 und das Zusammenpressen der Rückholfeder 20. Dadurch werden Überbelastungen der funktionswichtigen Innenteile vermieden, der Verschleiß und die Reparaturanfälligkeit werden erheblich reduziert.The bearing surface 52 limits the opening movement for the slide piston 14 and the compression of the return spring 20. This prevents overloading of the functionally important internal parts, and significantly reduces wear and the need for repairs.
