Description
Temperaturgesteuertes Durchflussregulierventil Die Erfindung bezieht sich auf ein temperatur gesteuertes Durchflussregulierventil, mit einem federbe lasteten Ventilschliesskörper, wie es zum Beispiel in mit der Warmwasserheizung kombinierten Boileranlagen zur temperaturabhängigen Regulierung verwendet wird.
Gemäss der Erfindung sind zwischen einem Ventil gehäuseteil und der zur Federbelastung entgegenge setzten Seite des Ventilschliesskörpers in der Bewe gungsrichtung des letzteren mehrere, sich unter Wärme einfluss bombierende Bimetallscheiben in einer Reihe hintereinander angeordnet, wobei die Bombierung von einander benachbarten Scheiben entgegengesetzt ver läuft, so dass bei Zunahme der Bombierung der Schliesskörper entgegen der Federbelastung bewegt wird.
Ein Ausführungsbeispiel des erfindungsgemässen Durchflussregulierventils ist auf der Zeichnung im Axialschnitt dargestellt.
Der im Ventilgehäuse 1 axialgeführteVentilschliess- körper 2 ist einenends durch eine an einem zu ihm koaxialen Schraubdeckel 3 des Gehäuses 1 abge stützte Schraubenfeder 4 belastet, welche den Schliess körper in seiner die Ventilöffnung 5 schliessenden Lage zu halten sucht. Auf der axial entgegengesetzten Seite weist der Schliesskörper 2 einen koaxialen Gewinde zapfen 6 auf, auf welchen eine zylindrische Schliess körperstange 7 axial einstellbar und mittels einer Mutter 8 gesichert mit ihrem hülsenförmigen Ende 9 aufgeschraubt ist. Diese Stange ist mit ihrem andern Ende in einem mit dem Ventilgehäuse verschraubten, hohlzylindrischen Tauchkörper 10 koaxial geführt.
Zwischen der geschlossenen Stirnseite des Tauchkör pers und dem hülsenförmigen Ende 9 der Stange 7 sind auf der letzteren mehrere Bimetall-Ringscheiben 11, welche zum Beispiel aus aufeinandergewalztem Nickel- und Eisenblech bestehen, in einer Reihe hintereinander verschiebbar angeordnet. Diese Ring scheiben sind bei Zimmertemperatur flach und er fahren eine mit steigender Temperatur zunehmende Bombierung, welche bei einander benachbarten Schei ben entgegengesetzt verläuft.
Bei Zunahme der Bom- bierung gelangt daher die Scheibenreihe zunächst einerseits an der Tauchkörperstirnseite und ander seits an der als Anschlag dienenden Stangenhülse 9 zum Anstehen (vgl. Zeichnung), und schliesslich wird der Ventilschliesskörper entgegen der Wirkung der Schliessfeder 4 aus der Schliesslage bewegt.
Durch Ändern der Anzahl der Bimetallscheiben 11 kann nicht nur die für den Öffnungsbeginn des Ventils massgebende Temperatur, sondern auch das Verhältnis des Öffnungsweges zum Temperaturanstieg geändert werden. Die Feineinstellung erfolgt mittels der Verschraubung zwischen der Stange 7 und dem Schliesskörper 2.
Temperature-controlled flow regulating valve The invention relates to a temperature-controlled flow regulating valve, with a spring-loaded valve closing body, as is used, for example, in boiler systems combined with hot water heating for temperature-dependent regulation.
According to the invention, several bimetallic disks cambering under the influence of heat are arranged in a row one behind the other between a valve housing part and the side of the valve closing body opposite to the spring load, in the direction of movement of the latter, the camber of adjacent disks running in opposite directions, so that as the crown increases, the closing body is moved against the spring load.
An embodiment of the flow regulating valve according to the invention is shown in the drawing in an axial section.
The valve closing body 2 axially guided in the valve housing 1 is loaded at one end by a helical spring 4 supported on a screw cap 3 of the housing 1 that is coaxial with it and which seeks to hold the closing body in its position in which the valve opening 5 closes. On the axially opposite side, the closing body 2 has a coaxial thread pin 6 on which a cylindrical closing body rod 7 is axially adjustable and secured with its sleeve-shaped end 9 by means of a nut 8. This rod is guided coaxially with its other end in a hollow cylindrical immersion body 10 screwed to the valve housing.
Between the closed end face of the Tauchkör pers and the sleeve-shaped end 9 of the rod 7, several bimetallic washers 11, which for example consist of rolled nickel and iron sheets, are arranged in a row one behind the other. These ring washers are flat at room temperature and he drives a crown that increases with increasing temperature, which runs in opposite directions in adjacent discs.
When the camber increases, the row of disks comes to rest against the front of the immersion body on the one hand and on the rod sleeve 9 serving as a stop on the other (see drawing), and finally the valve closing body is moved out of the closed position against the action of the closing spring 4.
By changing the number of bimetallic disks 11, not only the temperature which is decisive for the start of opening of the valve, but also the ratio of the opening path to the temperature rise can be changed. The fine adjustment takes place by means of the screw connection between the rod 7 and the closing body 2.
