Description

Zweck der Erfindung gegenüber bekannten Sicherheitsventilen ist, durch Vermeiden jeder Reibung in der Ventilführung verspätetes Öffnen oder Längenbleiben des Ventils auszuschließen. Statt eine Gleitführung oder ein Gelenk zu verwenden, wird deshalb der Ventilabschlußkörper von einem Hebel geführt, dessen bewegliche Verbindung mit dem Ventilgehäuse bzw. mit der Ventilgrundplatte erfindungsgemäß aus einem oder mehreren Federblättern besteht.The purpose of the invention over known safety valves is through Avoid any friction in the valve guide, opening it too late or staying too long exclude the valve. Instead of using a sliding guide or a joint, therefore the valve closure body is guided by a lever, its movable Connection with the valve housing or with the valve base plate according to the invention consists of one or more spring leaves.

Die Erfindung ist in einem ;lusführungsbeispiel dargestellt. Es zeigt _1bb. i einen Längsschnitt durch das Sicherheitsventil, Abb. 2 eine Draufsicht.The invention is shown in an exemplary embodiment. It shows _1bb. i a longitudinal section through the safety valve, Fig. 2 a plan view.

Auf einer einen Teil des Ventilgehäuses bildenden Platte i befindet sich der Ventilsitz 2 und die Spannschraube 3 der `'entilbelastungsfeder. Aiii Ende der Platte sitzt die im wesentlichen aus einem Federblatt .4 bestehende bewegliche Verbindung des Ventilhebels 5 mit dem Ventilgehäuse i. Der Ventilhebel 5 gibt dem N'entilal>schlußkörper 6 die Führung. Zur Betriebssicherheit kann das Federblatt .4 in mehrere nebeneinanderliegende Federblätter unterteilt werden.Located on a part of the valve housing forming plate i the valve seat 2 and the tensioning screw 3 of the valve loading spring. Aiii the end the plate sits essentially consisting of a spring leaf .4 movable Connection of the valve lever 5 to the valve housing i. The valve lever 5 gives the N'entilal> closing body 6 the guide. For operational safety, the spring leaf .4 be divided into several adjacent spring leaves.
