Description

Wärmeregler mit einem durch eine Membran gedrosselten Hauptventil und einem ein Hilfsventil steuernden Wärmefühler aus Hartgummi Es sind Temperaturregler bekannt, bei denen die Zufuhr des Heizmittels durch einen Hilfsstrom gesteuert wird, dessen Druck durch eine einstellbare Drosselung und ein durch einen Wärmefühler gesteuertes Hilfsventil beeinflußt ,wird, so daß sich eine das Hauptventil tragende Membran hebt oder senkt.Thermal regulator with a main valve throttled by a diaphragm and a hard rubber heat sensor controlling an auxiliary valve. They are temperature regulators known, in which the supply of the heating medium is controlled by an auxiliary stream, its pressure by an adjustable throttle and by a heat sensor Controlled auxiliary valve is influenced, so that a main valve supporting Diaphragm raises or lowers.

Der Wärmefühler ist bei Reglern dieser Art auf einer an der Wand zu befestigender: Grundplatte angebracht und mit dem Regelventil durch Hilfsrohre verbunden. Die Regeleinrichtung besteht also aus zwei örtlich getrennten Teilen. Das Hartgummirohr des Wärmefühlers muß dabei verhältnismäßig lang sein, damit man dem Hilfsventil des Fühlers einen großen Hub geben kann, um trotz beträchtlicher Länge der möglichst schwach gehaltenen Hilfsrohre die ganze Einrichtung genügend temperaturempfindlich zu machen.With controllers of this type, the heat sensor is on one on the wall fastening: base plate attached and connected to the control valve by auxiliary pipes. The control device thus consists of two spatially separated parts. The hard rubber pipe of the heat sensor must be relatively long so that the auxiliary valve of the sensor can give a large stroke, despite the considerable length of the possible weakly held auxiliary pipes make the whole facility sufficiently temperature-sensitive close.

Den Gegenstand der Erfindung bildet ein Wärmeregler, insbesondere für Gasfeuerungen, mit einem durch eine Membran geführten Hauptventil und einem ein Hilfsventil steuernden Wärmefühler aus Hartgummi, bei denen- Regelventil, Hilfsventil und Wärmefühler eine Baueinheit bilden und in einer Achse liegen.The subject matter of the invention is a heat regulator, in particular for gas firing, with a main valve guided through a membrane and a an auxiliary valve controlling a heat sensor made of hard rubber, in which- control valve, auxiliary valve and heat sensors form a structural unit and lie in one axis.

Auf der Zeichnung ist ein Ausführungsbeispiel im Längsschnitt dargestellt.In the drawing, an embodiment is shown in longitudinal section.

Das in die Gasleitung eingeschaltete Ventilgehäuse a enthält das von einer Membran b geführte Regelventil c und trägt zugleich den Wärmefühler, der im wesentlichen aus einem hohlen Hartgummikörper f, einem darin befindlichen, mit ihm durch den Kopfteil g einstellbar verbundenen Stahlstabe h und einem an dessen freiem Ende befestigten Hilfsventil i besteht. Letzteres beherrscht einen Hilfsgasstrom, der durch eine im Innern des Ventilgehäuses a angeordnete Zweigleitung o durch den Raum über der Membran b in den Hartgummikörper f und weiter durch einet: Kanal g zur Brennstelle fließt.The valve housing a, which is connected to the gas line, contains that of a diaphragm b guided control valve c and at the same time carries the heat sensor, which is in essentially of a hollow hard rubber body f, one located in it, with him adjustable by the head part g connected steel rod h and one at its free End attached auxiliary valve i consists. The latter controls an auxiliary gas flow, by a arranged in the interior of the valve housing a branch line o through the Space above the membrane b into the hard rubber body f and further through one: channel g flows to the burning point.

Die in feintretende Gasmenge wird durch die verschiedene Wärmeausdehnung des Hartgummikörper s f und des Stahlstabes h in :3bhängigkeit von der Raumtemperatur durch das Hilfsventil i gesteuert, dadurch wird der auf die Membran b wirkende Rück des Hilfsgases verändert, so daß das Hauptventil c je nach der Durchbiegung der Membran den Hauptgasstrom drosselt oder freigibt.The amount of gas entering fine is due to the various thermal expansion of the hard rubber body s f and of the steel rod h in: 3dependence on the room temperature controlled by the auxiliary valve i, thereby acting on the diaphragm b back of the auxiliary gas changed so that the main valve c depending on the deflection of the Membrane throttles or releases the main gas flow.

Durch die Anordnung des Hilf svelitils i und des Hartgummikörpers f in einer Achse mit dem Hauptventil c wird der Gesamtaufbau und die Zugänglichkeit des Ganzen besonders einfach und die Anschlußlänge des Gerätes auf ein Mindestmaß gebracht.By the arrangement of the auxiliary svelitils i and the hard rubber body f in one axis with the main valve c is the overall structure and accessibility The whole thing is particularly simple and the connection length of the device to a minimum brought.

Der Hartgummikörper f ist zweckmäßig zylindrisch, er kann aber auch kegelförmig oder anders gestaltet sein.The hard rubber body f is expediently cylindrical, but it can also be conical or designed differently.
