Description

Die Erfindung betrifft ein Thermosiat-Radiatorventil gemäß dem Oberbegriff des Anspruches 1. Ein derartiges Thermostat ist aus der DE-AS 19 07 231 bekannt-The invention relates to a Thermosiat radiator valve according to the preamble of claim 1. A Such a thermostat is known from DE-AS 19 07 231-

Aus der DE-OS 17 98 294 ist auch schon ein Thermostat-Radiatorventil bekannt, dessen von dem Ventil abgesetzter Fühler mit einer heizeinrichtung versehen ist Bei eingeschalteter Heizeinrichtung wird dem Fühler also eine Erhöhung der Raumtemperatur vorgetäuscht Trotzdem soll die Regelfunktion des Fühlers erhalten bleiben. Diese Aufgabe ist mit dem bekannten Thermostat nur unzureichend gelöst Zudem bereitet die Anbringung der Heizeinrichtung an dem Fühler dann Schwierigkeiten, wenn der Fühler Bestandteil des Ventils selbst ist, wie bei dem Thermostat der einleitend angegebenen Gattung. Ferner führt die Wärmeübertragung durch Wärmeleitung zu ungleichmäßiger Temperaturverteilung auf dem Fühler und damit zu einem unbefriedigenden Regelverhalten desFrom DE-OS 17 98 294 a thermostatic radiator valve is already known, of which The valve remote sensor is provided with a heating device When the heating device is switched on So the sensor simulates an increase in room temperature. Nevertheless, the control function of the Sensor are retained. This task is only inadequately achieved with the known thermostat the attachment of the heating device to the sensor causes difficulties when the sensor is a component of the valve itself is, as in the case of the thermostat, of the type specified in the introduction. Furthermore, the Heat transfer by conduction leads to uneven temperature distribution on the sensor and thus to an unsatisfactory control behavior of the

Die gleichen Nachteile weist auch ein aus der DE-OS 2139 812 bekanntes Tbermostat-Regelventil auf.The same disadvantages are also found in the DE-OS 2139 812 well-known thermostatic control valve.

Der Erfindung liegt die Aufgabe zugrunde, einThe invention is based on the object Thermostat-Radiatoryentil der einleitend angegebenenThermostatic radiator valve of the initially specified Gattung zu schaffen, das eine Nachtabsenkung unterGenerate to create a night setback below Beibehaltung des Prinzips der DurchflußdrosselungRetention of the principle of flow restriction

gestattetallowed

Diese Aufgabe ist erfindungsgemäß dadurch gerast,According to the invention, this task is achieved by

ίο daß zwischen dem Ventilgehäuse und dem dieses übergreifenden Teil des Handgriffes ein ringförmiger Raum zur Aufnahme einer elektrischen Heizeinrichtung vorgesehen ist, der mit dem den Fühler umgebenden Raum in Verbindung stehtίο that between the valve housing and this overlapping part of the handle an annular space for receiving an electrical heating device is provided, which is in communication with the space surrounding the sensor

Hierdurch wird erreicht, daß die Heizeinrichtung ortsfest bleibt und einschließlich ihrer Zuleitungsdrähte keinerlei mechanischen Beanspruchungen ausgesetzt ist Die Heizleistung ist leicht dotierbar. Die Wärmeübertragung erfolgt weitgehend durch Konfektion.This ensures that the heating device remains stationary and, including its lead wires, is not exposed to any mechanical stresses The heating power can be easily doped. The heat transfer takes place largely through assembly.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schemaiisch dargestellt Ein feststehendes Ventiloberteil ist von einem ringförmigen Raum 5 umgeben, den ein Gehäuse einnimmt, in dem elektrische Heizwiderstände 6 angeordnet sind, mittels derer die gewünschte Nachtabsenkung vorgenommen wird. Die elektrischen Heizwiderstände 6 sind mittels Anschlußdrähte an einem Klemmkasten 8 so angeschlossen, daß sowohl die elektrischen Heizwiderstände 6 als auch der Klemmkasten 8 und die Anschlußdrähte am Klemmkasten 8 in Bezug auf das Ventiloberteil 7 ortsfest angeordnet sind und an der Drehbewegung eines Handgriffes 1 nicht teilnehmen. Die von den elektrischen Heizwiderständen 6 ausgestrahlte Wärme gelangt über einen Raum 4 und Luftkanäle 3 zu einem Fühler 2. Die hierdurch bewirkte Temperaturerhöhung an dem Fühler 2 führt zu einer Vergrößerung des Volumens dessen Wachsfüllung. Diese Volumenvergrößerung im Fühler 2 führt zu einer Abwärtsbewegung eines Ventilkörpers 9. Der Durchfluß de- Heizungsvorlauf-Wassers zum Heizkörper wird dadurch verkleinert Mit der Verkleinerung der durch einen Heizkörper fließende Wassermenge wird auch die Wärmeabgabe verkleinert. Damit wird die Temperatur des zu beheizenden Raumes heruntergesetzt Die Dauer der Beheizung der elektrischen Heizwiderstände und damit die Dauer der Nachtabsenkung wird auf einer elektrischen Zeitschaltuhr 10 eingestellt.In the drawing, an embodiment of the invention is shown schematically A fixed Valve top is surrounded by an annular space 5, which occupies a housing in which electrical Heating resistors 6 are arranged, by means of which the desired night reduction is made. the electrical heating resistors 6 are connected by means of connecting wires to a terminal box 8 so that both the electrical heating resistors 6 and the terminal box 8 and the connecting wires on the terminal box 8 with respect to the upper valve part 7 are arranged stationary and on the rotational movement of a Handle 1 does not participate. The heat radiated from the electrical heating resistors 6 arrives Via a room 4 and air ducts 3 to a sensor 2. The temperature increase caused by this at the sensor 2 leads to an increase in the volume of its wax filling. This increase in volume in the sensor 2 leads to a downward movement of a valve body 9. The flow of the heating flow water to the radiator is thereby reduced in size with the reduction of the through a radiator The amount of flowing water also reduces the heat dissipation. This increases the temperature of the heating room reduced The duration of the heating of the electrical heating resistors and thus the duration of the night reduction is set on an electrical timer 10.
