Description
Temperaturregler für Gasfeuerstätten Gegenstand der Erfindung ist ein einstellbarer Temperaturregler für Gasfeuerstätten, der im Vergleich zu den bisher bekannt gewordenen Reglern dieser Art dadurch besonders einfachen Aufbau und große Betriebssicherheit erhalten hat, daß für die Einstellung erfindungsgemäß die axiale Verschraubung zwischen dem den Gaseinlaß- und den Gasauslaßstutzen sowie den Wärmefühler tragenden Gehäuseteil und einem zweiten Gehäuseteil (Schale) benutzt wird, in welchem das Reglerventil und der zugehörige Ventilsitz untergebracht sind.Temperature controller for gas fireplaces is the subject of the invention an adjustable temperature controller for gas fireplaces that compares to the Controllers of this type that have become known up to now are therefore particularly simple in structure and great operational reliability has been obtained that according to the invention for the setting the axial screw connection between the gas inlet and the gas outlet nozzle as well as the housing part carrying the heat sensor and a second housing part (shell) are used in which the regulator valve and the associated valve seat are housed.
Ein Ausführungsbeispiel ist in der Zeichnung in einem Axialschnitt, teilweise in Seitenansicht dargestellt.An exemplary embodiment is shown in the drawing in an axial section, partially shown in side view.
Das Reglergehäuse besteht aus den beiden Schalen a und b. Die Schale b ist mit dem Gaseinlaßstutzen i und dem Gasauslaßstutzen m versehen und trägt den Wärmefühlkörper,_ der aus einem in ihr befestigten Rohr f und einem im Rohr längsverschiebbaren Stab d besteht. Das Rohr f hat einen größeren Wärmeausdehnungskoeffizienten als d''''er Stab d.The controller housing consists of the two shells a and b. The shell b is provided with the gas inlet nozzle i and the gas outlet nozzle m and carries the heat sensor, which consists of a tube f fixed in it and a rod d which can be moved longitudinally in the tube. The tube f has a greater coefficient of thermal expansion than d '''' he rod d.
In der Schale a ist der Ventilsitz e und das zugehörige Ventil c untergebracht, die beide möglichst großen Durchmesser besitzen, so daß in an sich bekannter Weise die Ventilöffnung auch bei kleiner Ventilbewegung möglichst groß wird. Auf das Ventil c wirkt die ebenfalls in der Schale a untergebrachte Ventilfeder.The valve seat e and the associated valve c are housed in the shell a, both of which have the largest possible diameter, so that in a manner known per se the valve opening becomes as large as possible even with a small valve movement. On the valve c acts the valve spring, which is also housed in shell a.
Die Schale a ist erfindungsgemäß in die Schale b in axialer Richtung einschraubbar. Durch weiteres Hineinschrauben der Schale a in b wird das Ventil c dem Stab d des Wärmefühlers genähert und schließlich vom Ventilsitz e abgehoben.According to the invention, the shell a is in the shell b in the axial direction screwable. By further screwing in the shell a in b, the valve c approached the rod d of the heat sensor and finally lifted off the valve seat e.
Das Gas gelangt aus dem Stutzen i in das Innere der Schale a durch einen in der Schale b vorgesehenen Umlaufkanal k mit Löchern 1. The gas passes from the nozzle i into the interior of the shell a through a circulation channel k with holes 1 provided in the shell b.
Die Einstellung der Schale a in der Schale b kann an der Temperatureinstellung g einer auf die Schale a gesetzten Kappe abgelesen werden, die sich über dem entsprechend zylindrisch gestalteten Hals der Schale b an einer daran angebrachten Marke vorbeidreht.The setting of the bowl a in the bowl b can be read from the temperature setting g of a cap placed on the bowl a, which turns over the correspondingly cylindrical neck of the bowl b past a mark attached to it.
Die Zeichnung zeigt den Regler in Nichtgebrauchstellung bzw. in der Stellung, die er bei sehr hoher Außentemperatur einnimmt, bei welcher demzufolge der Gasdurchfluß abgesperrt ist.The drawing shows the controller in the non-use position or in the Position that it assumes when the outside temperature is very high, and consequently at which the gas flow is shut off.
Soll geheizt werden, so wird die Schale a in die Schale b so weit hineingeschraubt, daß das Ventil c sich auf den Stab d des Wärmefühlers aufsetzt und dadurch geöffnet wird. Tritt sodann eine Temperatursteigerung ein, so dehnt sich das Rohr f mehr aus als der Stab d. Letzterer weicht zurück und läßt das Ventil c seinem Sitz e sich nähern, bis schließlich der Gasdurchlaß gänzlich abgesperrt wird.If it is to be heated, the shell a is screwed into the shell b so far that the valve c sits on the rod d of the heat sensor and is thereby opened. If the temperature then increases, the tube f expands more than the rod d. The latter moves back and lets the valve c approach its seat e until finally the gas passage is shut off completely.
Die Temperatur, bei welcher dies eintritt, läßt sich durch entsprechende Drehung der Schale a in ihrem Verschraubungsgewinde bequem und genau einstellen.The temperature at which this occurs can be determined by appropriate Conveniently and precisely adjust the rotation of the shell a in its screw thread.
