Description
Gegenstand der Erfindung ist ein Membrandruckregler nach Patent 944661 mit einem auf Membranen befestigten hohlen Ventilsitzkörper, der frei schwebend ohne besondere Führung gegen einen oberhalb des Ventilsitzkörpers angeordneten Ventilteller hin beweglich ist, wobei der Ventilsitzkörper als Venturidüse ausgebildet ist. Insbesondere bezieht sich die vorliegende Erfindung auf einen Membrandruckregler dieser Art, bei dem der Eingang und der Ausgang des Reglers in seiner Mittelachse angeordnet sind.The subject of the invention is a diaphragm pressure regulator according to patent 944661 with a hollow valve seat body attached to membranes and floating freely without special guidance against a valve disk arranged above the valve seat body is movable towards, wherein the valve seat body is designed as a Venturi nozzle. In particular the present invention relates to a diaphragm pressure regulator of this type, in which the input and the output of the controller are arranged in its central axis are.
Die Erfindung bezweckt, einen Regler dieser Art wesentlich zu vereinfachen. Zu diesem Zweck besteht die Erfindung darin, daß der Boden des Eingangsstutzens zugleich als Ventilteller oder Träger desselben ausgebildet ist. Vorzugsweise ist ferner die Ausgleichsmembran, über die der obere Rand der Venturidüse überhängt, an einem Lötring des Gehäuseoberteils aufgehängt. Die Befestigungsmutter für die Ventilteile kann zugleich als Belastungsgewicht für die Membran ausgebildet sein. Zweckmäßig besteht die Sicherheitseinrichtung in einer Sicherungsdüse im Gehäuseoberteil. Schließlich ist die Venturidüse in Richtung auf den Ausgang des Reglers wirkend angeordnet, wodurch ein Sog und damit ein Unterdruck unter der Membran gegenüber dem Reglerausgang erzeugt wird.The aim of the invention is to substantially simplify a controller of this type. To this end, the invention consists in that the bottom of the inlet nozzle is designed at the same time as the same valve plate or carrier. Preferably is also the compensating membrane over which the upper edge of the Venturi nozzle overhangs, suspended from a soldering ring on the upper part of the housing. The fastening nut for the Valve parts can also be designed as a loading weight for the membrane. The safety device expediently consists of a safety nozzle in the upper part of the housing. Finally, the venturi acts in the direction of the output of the regulator arranged, whereby a suction and thus a negative pressure under the membrane opposite the controller output is generated.
Zwei Ausführungsbeispiele des Gegenstandes der Erfindung sind in der Zeichnung dargestellt, es zeigt Abb. I einen Membrandruckregler im senkrechten Schnitt, Abb. II eine Ansicht einer anderen Ausführungsform mit geschnittenem Ausgangsstutzen.Two embodiments of the subject matter of the invention are shown in FIG Drawing shown, Fig. I shows a diaphragm pressure regulator in vertical section, Fig. II is a view of another embodiment with a cut outlet nozzle.
Das aus Gehäuseoberteil a und -unterteil c bestehende Reglergehäuse trägt je einen in der Gehäuseachse angeordneten Eingangs- und Ausgangsstutzen. Der Boden des Eingangsstutzens ist als Ventilteller b ausgebildet bzw. trägt diesen.The controller housing consisting of housing upper part a and lower part c carries one inlet and one outlet nozzle each arranged in the housing axis. Of the The bottom of the inlet connection is designed as a valve disk b or carries it.
Die Ausgleichsmembran e, über die wie beim Hauptpatent der obere Rand der Venturidüse k überhängt, ist an einem Lötring q des Gehäuseoberteils a aufgehängt. Die Befestigungsmutter ia für die Ventilteile ist zugleich als Belastungsgewicht für die Arbeitsmembran f ausgebildet. Die Sicherheitseinrichtung besteht in einer Sicherungsdüse r, die in der Wandung des Gehäuseoberteils a angeordnet ist. Die Venturidüse k wirkt in Richtung auf den Ausgang des Reglers, wodurch ein Sog und damit ein Unterdruck unter der Membran f gegenüber dem Reglerausgang erzeugt wird.The compensating membrane e, over which the upper edge of the Venturi nozzle k overhangs as in the main patent, is suspended from a soldering ring q of the upper housing part a. The fastening nut ia for the valve parts is also designed as a loading weight for the working diaphragm f. The safety device consists of a safety nozzle r, which is arranged in the wall of the upper housing part a. The Venturi nozzle k acts in the direction of the outlet of the regulator, whereby a suction and thus a negative pressure is generated under the membrane f in relation to the regulator outlet.
Abb. II zeigt den gleichen Regler, wie er in Abb. 1 dargestellt ist, jedoch mit winkligem Anschluß der Zuleitung und der Ableitung an die Eingangs- und Ausgangsstutzen.Fig. II shows the same regulator as shown in Fig. 1, but with angled connection of the supply line and the discharge line to the input and Outlet port.
