Die Erfindung wird nachstehend an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigtThe invention is described below using an exemplary embodiment shown in the drawing explained in more detail. It shows
F i g. 1 einen Längsschnitt durch ein Ventil gemäß der Erfindung undF i g. 1 shows a longitudinal section through a valve according to the invention and
Fig.2 eine Draufsicht auf den unteren Ventilteil bei abgenommenem thermostatischem Teil.2 shows a plan view of the lower valve part with the thermostatic part removed.
In einem Ventilgehäuse 1 arbeitet mit dem Ventilsitz! ein Verschlußglied 3 zusammen. Dieses wird über einen Schaft 4 von der Balgdose 5 eines thermostatischen Systems verstellt. Der Füllraum 6 dieses Systems ist mit Flüssigkeit gefüllt und steht über ein Kapillarrohr 7 mit dem thermostatischen Fühler in Verbindung. Durch eine Längenänderung des zweiten Balges 8 mit Hilfe des Drehknopfes 9 kann das Volumen des Füllraumes 6 verändert und dadurch der Sollwert des Durchflußquerschnitts des Ventils eingestellt werden.In a valve housing 1 works with the valve seat! a closure member 3 together. This is via a shaft 4 from the bellows box 5 of a thermostatic System misaligned. The filling space 6 of this system is filled with liquid and stands over Capillary tube 7 in connection with the thermostatic sensor. By changing the length of the second Bellows 8 with the help of the rotary knob 9 can change the volume of the filling space 6 and thereby the setpoint of the flow cross-section of the valve can be set.
Der thermostatische Teil des Ventils einschließlich des Drehknopfes ist abnehmbar, indem die Überwurfmutter 10 von dem oberen Teil 1 a des Gehäuses abgeschraubt wird.The thermostatic part of the valve including the rotary knob can be removed by unscrewing the union nut 10 from the upper part 1a of the housing.
Da der Aufbau und die Wirkungsweise eines bis hierher beschriebenen Ventils bekannt sind, wird von einer Erläuterung weiterer Einzelheiten, sofern sie nicht erfindungswesentlich sind, Abstand genommen.Since the structure and mode of operation of a valve described up to this point are known, from an explanation of further details, provided that they are not essential to the invention, dispensed with.
Zur Lösung der der Erfindung zugrunde liegenden Aufgabe ist nun an dem Ventilschaft 4 ein fester Anschlag 11 vorgesehen, der mit einer im oberen Gehäuseteil 1 α axial verschraubbaren Anschlagplatte 12 zusammenwirken kann. Die Anschlagplatte ist durch einen Spreizring 13 gegen ein Herausfallen und durch die Feder 14 gegen ein unbeabsichtigtes Verdrehen gesichert. Wie F i g. 2 deutlicher zeigt, besitzt die Anschlagplatte 12 einen Innenachtkant 15 und tragt an ihrer Oberseite eine Skala 16. Die abgewinkelten Enden 17 des Spreizringes können hierbei als Zeiger für die Skala 16 dienen.To achieve the object on which the invention is based, a fixed stop 11 is now provided on the valve stem 4, which stop can interact with a stop plate 12 which can be axially screwed into the upper housing part 1 α. The stop plate is secured against falling out by an expanding ring 13 and against unintentional rotation by the spring 14. Like F i g. 2 shows more clearly, the stop plate 12 has an inner octagon 15 and carries a scale 16 on its upper side. The angled ends 17 of the expansion ring can serve as pointers for the scale 16.
Es sei angenommen, daß in der veranschaulichten obersten Stellung der Anschlagplatte 12 (Skaleneinstellung auf 14) für die Bewegung des Ventilkörpers 3 der gesamte oder fast der gesamte Hub zur Verfügung steht, der von dem thermostatischen System aufgebracht werden könnte. In diesem Fall hat das Ventil den geringsten Durchflußwiderstand. Bei einer raschen Sollwert- oder Istwertänderung des thermostatischen Systems gelangt eine recht große Durchflußmenge durch das Ventil. Wenn man im Sinne der Erfindung eine gute Ausnutzung des Heizmediums im Heizkörper erzielen will, kommt diese Einstellung nur dort in Frage, wo das Heizmedium infolge eines großen Leitungswiderstandes nur mit geringer Durchflußgeschwindigkeit zur Verfügung steht. In allen anderen Fällen aber wird die Anschlagplatte mit Hilfe eines Außenachtkantschlüssels verschraubt, so daß sie sich in Richtung auf den Ventilsitz bzw. den Anschlag 11 an dem Ventilschaft 4 verschiebt. Der maximale Hub ist nunmehr durch die Anschläge 11, 12 begrenzt. Er ist kleiner, oft sogar erheblich kleiner als derjenige Hub, der infolge einer vollen Aussteuerung durch das thermostatische System auftreten würde. Der begrenzte Hub erhöht den Durchflußwiderstand am Ventil, so daß die Durchflußmenge des Heizmediums pro Zeiteinheit herabgesetzt bleibt und eine bessere Ausnutzung seiner Wärme im Heizkörper gewährleistet ist. Durch entsprechende Einstellung der Skala 16 kann man die zulässige maximale Öffnungsstellung des Ventils und damit dessen Durchflußwiderstand einjustieren. Man kann es daher erreichen, daß in einer Anlage sämtliche Heizkörper, die von diesen Ventilen bedient werden, bei voller Öffnungsstellung mit der gleichen Menge des Wärmeträgers pro Zeiteinheit beliefert werden, auch wenn die Durchflußwiderstände in den Zuleitungen, beispielsweise infolge unterschiedlicher Länge, verschieden sein sollten.It is assumed that in the illustrated uppermost position of the stop plate 12 (scale setting on 14) for the movement of the valve body 3 the entire or almost the entire stroke to Is available that could be applied by the thermostatic system. In this case it has the valve has the lowest flow resistance. In the event of a rapid change in the setpoint or actual value of the thermostatic system, a fairly large amount of flow passes through the valve. If you are in According to the invention, a good utilization of the heating medium in the radiator wants to be achieved, this comes Setting only in question, where the heating medium only with due to a high line resistance low flow rate is available. In all other cases, however, the stop plate screwed with the help of an external octagon wrench so that they are in the direction of the The valve seat or the stop 11 moves on the valve stem 4. The maximum stroke is now limited by the stops 11, 12. It is smaller, often even considerably smaller, than the stroke that results full modulation by the thermostatic system would occur. The limited stroke increases the flow resistance at the valve, so that the flow rate of the heating medium per unit of time remains reduced and a better utilization of its heat in the radiator is guaranteed. By Appropriate setting of the scale 16 can be used to determine the maximum permissible opening position of the valve and thus adjust its flow resistance. One can therefore achieve that in one plant all radiators operated by these valves with the fully open position the same amount of heat transfer medium per unit of time are supplied, even if the flow resistances in the supply lines, for example due to different lengths, should be different.

In the case of radiators, this means that it is also advantageous if the stop of the heat transfer medium is secured at high speed, the side of the plate facing the attachment is limited by the line resistance, by pulling a spreader ring, which leads to the inside and flows through the radiator. As a result, angled ends serve as pointers. The expansion ring of the short dwell time in the radiator takes place here 60 has a double function, which is therefore possible, poor utilization of the heat transfer medium. The because the scale is attached to the surface of the stop plate, targetable temperature, lowering of the heat transfer medium, which is secured by the expansion ring, depends on the local conditions (size of the .) for example using a diagram that shows the Drosab. The disadvantage described is particularly noticeable resistance above the associated scale value lig in those cases where the heat consumed is shown, which is determined by the water meter for the corresponding installation location, so make both settings,
