Description

Die Erfindung betrifft eine Vorrichtung fürThermostatventile mit den Merkmalen nach dem ersten Teil des Patentanspruchs 1.The invention relates to a device for thermostatic valves with the features according to the first part of claim 1.

Bei Raumheizungen ist es wünschenswert und zweckmäßig, die von einem Thermostatventil geregelte Raumtemperatur zeitweise abzusenken, ohne daß dabei das Thermostatventil betätigt werden muß.In space heating, it is desirable and expedient to temporarily lower the room temperature controlled by a thermostatic valve without the thermostatic valve having to be actuated.

Aus der DE-A-3 149 760 ist eine Vorrichtung zur zeitabhängigen Steuerung des Heizmitteldurchsatzes von Heizkörpern bekannt, bei der im Heizmittelkreislauf des Heizkörpers zwei Thermostatventile vorgesehen sind, deren eines einen zeitabhängig zu- und abschaltbaren Bypass aufweist.From DE-A-3 149 760 a device for time-dependent control of the heating medium throughput of radiators is known, in which two thermostatic valves are provided in the heating medium circuit of the heating element, one of which has a bypass that can be switched on and off according to time.

Diese bekannte Vorrichtung erfordert zwei räumlich voneinander getrennt installierte Thermostatventile, wobei eines dieser Ventile zusätzlich mit einem, in einem Bypass angeordneten, elektromagnetisch von einer Zeitschaltuhr ansteuerbaren Hilfsventil versehen ist.This known device requires two thermostatic valves installed spatially separated from one another, one of these valves additionally being provided with an auxiliary valve which is arranged in a bypass and can be controlled electromagnetically by a timer.

Diese Vorrichtung ist in der Installation und im Aufwand relativ teuer und erfordert zur Temperatureinstellung an den beiden Thermostatventile besondere Bedienungskenntnisse.This device is relatively expensive to install and cost and requires special operating knowledge to set the temperature on the two thermostatic valves.

Bei einer anderen, aus der DE-A-2 727 821 bekannten Vorrichtung zur Temperaturabsenkung thermostat-gesteuerter Heizkörper ist im Heizmittelvorlauf des Heizkörpers neben dem Thermostatventil ein elektrothermisch gesteuertes Ventil angeordnet, das von einer Zeitschaltuhr angesteuert werden kann.In another device known from DE-A-2 727 821 for lowering the temperature of thermostatically controlled radiators, an electrothermally controlled valve is arranged in the heating medium flow of the radiator next to the thermostatic valve and can be controlled by a timer.

Diese Vorrichtung ist mit dem Nachteil behaftet, daß bei einem Absinken der Raumtemperatur sich das Thermostatventil stärker öffnen kann und es dann erforderlich ist, mit dem zeitgesteuerten Ventil, das dort als Drossel wirkt, einen größeren Heizmittelzufluß zum Heizkörper steuerungstechnisch entgegen zu wirken.This device has the disadvantage that when the room temperature drops, the thermostatic valve can open more and it is then necessary to counteract a larger inflow of heating medium to the radiator in terms of control technology with the time-controlled valve, which acts there as a throttle.

Der Erfindung liegt die Aufgabe zugrunde, diese bekannten Nachteile zu beseitigen und eine Vorrichtung der eingangsgenannten Art zu schaffen, die nicht nur eine hysteresearme Regelung des Heizmittelvorlaufs ermöglicht, sondern auch in ihrem Aufbau einfach ist.The invention has for its object to eliminate these known disadvantages and to provide a device of the type mentioned, which not only enables low-hysteresis control of the heating medium flow, but is also simple in its construction.

Diese Aufgabe wird mit den Merkmalen im kennzeichnenden Teil des Patentanspruchs 1 gelöst und in den abhängigen Ansprüchen sind weitere vorteilhafte Merkmale beansprucht.This object is achieved with the features in the characterizing part of patent claim 1 and further advantageous features are claimed in the dependent claims.

Vorteilhaft bei dieser Vorrichtung ist nicht nur die regelungstechnisch zweckmäßige Abhängigkeit zwischen der selbsttätigen Raumtemperaturregelung durch das Thermostatventil, das in seiner eingestellten Stellung belassen werden kann, und einer gewünschten zeitweisen Absenkung der Raumtemperatur, zur Erzielung einer hysteresearmen und schnellen Regelung, sondern auch der einfache und übersichtliche Aufbau der Vorrichtung in einem einfach installierbaren Ventilgehäuse, in welchem alle aktiven und passiven Einzelteile der Vorrichtung gemeinsam zueinander angeordnet sind.An advantage of this device is not only the control-related dependency between the automatic room temperature control by the thermostatic valve, which can be left in its set position, and a desired temporary lowering of the room temperature to achieve low-hysteresis and fast control, but also the simple and clear Structure of the device in an easily installable valve housing in which all active and passive individual parts of the device are arranged together.

Die Erfindung wird anhand eine Ausführungsbeispiels in der Zeichnung im folgenden näher erläutert. Es zeigen

  • Fig. 1 eine Schnittansicht durch ein Ventilgehäuse mit einer Vorrichtung nach der Erfindung und mit einer, um den Kopf des Thermostat-Reglers ringförmig angeordneten Zeitsteuereinrichtung des dritten Ventils und
  • Fig. 2 eine Vorderansicht auf eine Vorrichtung nach Fig. 1.
The invention is explained in more detail below using an exemplary embodiment in the drawing. Show it
  • Fig. 1 is a sectional view through a valve housing with a device according to the invention and with a, arranged around the head of the thermostat regulator ring control device of the third valve and
  • FIG. 2 shows a front view of a device according to FIG. 1.

Die, in der Fig. 1 dargestellte, Bauausführung der Vorrichtung besteht im einzelnen aus einem Ventilgehäuse 14, in welchem alle aktiven und passiven Einzelteile der Vorrichtung zueinander angeordnet sind. 15 bezeichnet die Eintrittsöffnung und 16 die Austrittsöffnung des Heizmittels am Ventilgehäuse 14. Beide Öffnungen 15 und 16 können mit insallationskonformen Einrichtungen, wie Gewinde, Flansche, Muttern oder sonstigen Mitteln versehen sein. Die Eintrittsöffnung 15 mündet dort in den Ventilraum 17, in dem die Ventilsitze 18 für das zeitgesteuerte dritte Ventil 3 und 19 für das thermostatgesteuerte zweite Ventil 5 mit den jeweils zugehörigen Ventilkegeln 20 und 21 angeordnet ist.The construction of the device shown in FIG. 1 consists in detail of a valve housing 14 in which all active and passive individual parts of the device are arranged relative to one another. 15 denotes the inlet opening and 16 the outlet opening of the heating means on the valve housing 14. Both openings 15 and 16 can be provided with installation-conforming devices, such as threads, flanges, nuts or other means. The inlet opening 15 opens there into the valve chamber 17, in which the valve seats 18 for the time-controlled third valve 3 and 19 for the thermostatically controlled second valve 5 with the associated valve cones 20 and 21 are arranged.

Der Ventilkegel 21 des zweiten Ventils 5, ist dort auf der Betätigungswelle 22 des thermostatgesteuerten Ventils 1 einstellbar gelagert. Zu diesem Zweck ist die Betätigungswelle 22 mit einem Gewinde 23 versehen, auf dem eine Stellmutter 24 als Anschlag ausgebildet ist, sodaß der Ventilkegel 21 des zweiten Ventils 5 axial einstellbar gegenüber dem Ventilkegel 25 des ersten Ventils 1 ist. Mit dieser Einstellung erfolgt die Vorwahl des Temperaturabsenkungswertes gegenüber der Temperatureinstellung des Reglers 2 am thermostatgesteuerten ersten Ventil 1. Der Ventilkegel 21 kann dort axial bis zur punktiert gezeichneten Position verschoben werden. Der Ventilkegel 21 wird durch eine axial wirkende Druckfeder 26 in Richtung des Ventilkegels 25 gehalten. Zwischen den Ventilkegel 21 und 25 ist der Bypass 4 der Vorrichtung wirksam.The valve cone 21 of the second valve 5 is adjustably mounted there on the actuating shaft 22 of the thermostatically controlled valve 1. For this purpose, the actuating shaft 22 is provided with a thread 23 on which an adjusting nut 24 is designed as a stop, so that the valve cone 21 of the second valve 5 is axially adjustable relative to the valve cone 25 of the first valve 1. With this setting, the temperature reduction value is preselected compared to the temperature setting of the controller 2 on the thermostatically controlled first valve 1. The valve cone 21 can be displaced axially there to the position shown in dotted lines. The valve cone 21 is held in the direction of the valve cone 25 by an axially acting compression spring 26. The bypass 4 of the device is effective between the valve cones 21 and 25.

10 bezeichnet die Zeitschaltuhr zur unmittelbaren Steuerung des Ventils 3, insbesondere über ein Gestänge 11. Die Zeitschaltuhr 10 ist insbesondere ringförmig um den Kopf des Reglers 2 des ersten Ventils 1 angeordnet. Die Zeitschaltuhr 10 kann erforderlichenfalls völlig autonom mit einer eigenen Stromversorgung oder einer sonstigen geeigneten Energieversorgung versehen sein und über einen größeren Zeitraum wartungsfrei arbeiten.10 denotes the timer for direct control of the valve 3, in particular via a linkage 11. The timer 10 is in particular arranged in a ring around the head of the controller 2 of the first valve 1. The time switch 10 can, if necessary, be provided completely autonomously with its own power supply or other suitable energy supply and work maintenance-free over a longer period.

In der Fig. 2 bezeichnet 10 die Zeitschaltuhr mit einer einstellbaren Zeitscheibe 27 mit einem Zifferblatt 28 und mit vorwählbaren Schaltreiter 29. 14 bezeichnet das Ventilgehäuse, das aus einem Metallguß oder aus Kunststoff hergestellt sein kann.In FIG. 2, 10 denotes the time switch with an adjustable time slice 27 with a dial 28 and with preselectable switching tabs 29. 14 denotes the valve housing, which can be made from a cast metal or from plastic.

Die Funktion der Vorrichtung ist nun folgende : Im sogenannten Tagbetrieb, wo keine Temperaturabsenkung erforderlich oder erwünscht ist, regelt das erste thermostatgesteuerte Ventil 1 die Raumtemperatur. Das dritte, zeitgesteuerte, Ventil 3 ist dabei geöffnet. Das zweite, mit dem thermostatgesteuerten Ventil 1 gekoppelte, Ventil 5 kann dort geöffnet sein, z. B. wenn die Raumtemperatur um den (Nacht-) Temperaturabsenkungsbetrag unter der Tagtemperatur liegt.The function of the device is now as follows: in so-called daytime operation, where no temperature reduction is required or desired, the first thermostatically controlled valve 1 controls it Room temperature. The third, time-controlled, valve 3 is open. The second, coupled to the thermostatically controlled valve 1, valve 5 can be opened there, for. B. if the room temperature is below the daytime temperature by the (night) temperature reduction amount.

Im sogenannten Nachtbetrieb, wo die Temperaturabsenkung erwünscht und programmiert ist, ist das dritte, zeitgesteuerte, Ventil 3 durch die Funktion der Zeitschaltuhr 10 von dieser über das Gestänge 11 geschlossen gehalten. Das zweite Ventil 5 öffnet sich nun bei Erreichung des Absenkungstemperaturwertes, der an der Stellmutter 24 eingestellt wurde, indem dort der Ventilkegel 21 gegenüber dem Ventilkegel 25 des ersten Ventils 1 vorwählbar verändert wurde. Das zweite Ventil 5 wirkt dort demnach um die Absenkungstemperatur verzögert gegenüber dem ersten Ventil 1.In the so-called night mode, where the temperature reduction is desired and programmed, the third, time-controlled, valve 3 is kept closed by the timer 10 by means of the function thereof via the linkage 11. The second valve 5 now opens when the lowering temperature value has been reached, which was set on the adjusting nut 24, by changing the valve cone 21 in a preselectable manner with respect to the valve cone 25 of the first valve 1. Accordingly, the second valve 5 is delayed by the lowering temperature compared to the first valve 1.
