Description

Bei den bekannten Abflußventilen für brennbare Flüssigkeiten oder Gase, bei denen der Ventilkegel bei starker Erhöhung der Temperatur in seiner Umgebung nach Zerstörung eines Anschlages aus leicht schmelzbarer Masse durch eine Feder auf seinen Sitz gedrückt wird, tritt leicht ein Festsetzen des Ventilkegels auf der Spindel ein, so daß die Einrichtung im Falle der Gefahr versagt. UmIn the known drain valves for combustible Liquids or gases in which the valve cone increases significantly in temperature in its vicinity after the destruction of a stop made of easily meltable mass is pressed onto its seat by a spring, the valve cone easily jams on the spindle so that the device fails in the event of danger. Around

ίο diesen Mangel zu beseitigen, ist gemäß vorliegender Erfindung der Ventilkegel auf der Spindel zwischen dem leicht schmelzbaren Anschlage und einem zweiten Anschlage, der die Bohrung des Ventilkegels durch eine Kegelfläche abdichtet, beweglich.ίο to remedy this deficiency is in accordance with the present Invention of the valve cone on the spindle between the easily fusible stop and a second stop which the bore of the valve plug through a Seals conical surface, movable.

Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiel in- einem Schnitt durch die Achse der Ventilspindel dar. Auf der Ventilspindel α sitzt in bekannter Weise die Scheibe b aus einer leicht schmelzbaren Masse. Oberhalb derselben sitzt auf der Ventilspindel eine Scheibe c, deren Abstand von der Scheibe b von solcher Größe ist, daß der Ventilkegel d sich um ein gewisses Stück auf der Spindel α verschieben kann.The drawing shows the subject matter of the invention in an exemplary embodiment in a section through the axis of the valve spindle. The disk b made of an easily meltable mass sits on the valve spindle α in a known manner. Above the same sits on the valve spindle a disk c, the distance from the disk b of such a size that the valve cone d can move a certain distance on the spindle α .

Wenn das Ventil geöffnet ist, so wird der Ventilkegel durch die Feder e an die Scheibe b angedrückt. Ist das Ventil geschlossen, so liegt der Ventilkegel an der Scheibe c an. Es findet also bei jedem öffnen und Schließen des Ventiles eine Verschiebung des Ventilkegels ä gegen die Spindel α statt, so daß ein Festsetzen des Kegels nicht eintritt.When the valve is open, the valve cone is pressed against the disk b by the spring e. When the valve is closed, the valve cone rests against disk c. There is therefore open at each and closing of the valve a displacement of the poppet ä against the spindle α held so that a setting of the cone does not occur.

Die Scheibe c ist an der dem Ventilteller zugekehrten Seite kegelförmig gestaltet und greift in eine kegelförmige Vertiefung am Ventilteller ein, so daß sie die Bohrung des Ventiltellers abdichtet.The disc c is designed and conical on the side facing the valve disk engages in a conical recess on the valve plate, so that it the bore of the Seals valve disc.
