Description

Absperrventile für heiße Medien, z. B. Heißwasserzapfventile des Sanitärarmaturenfaches, zeigen oft die unangenehme Erscheinung, daß sie einige Zeit nach dem Schließen zu tröpfeln beginnen. Das ist- darauf zurückzuführen, daß nach dem Schließen das Ventil wieder erkaltet und dann durch die Kontraktion der Ventilteile - Spindel, Kegelstück usw. - der feste Schließdruck der Dichtung nachläßt. Zur Behebung dieses Mangels ist bekanntgeworden, zwischen Dichtung und Schließteil des Ventils eine dünne Scheibe aus Federmetall anzuordnen, die beim Schließen so weit durchfedern soll, _ daß die spätere Kontraktion. ausgeglichen wird.Shut-off valves for hot media, e.g. B. hot water nozzles in the sanitary fittings compartment, often show the unpleasant appearance that they close after some time begin to trickle. This is due to the fact that after closing the valve cooled down again and then through the contraction of the valve parts - spindle, cone etc. - the firm closing pressure of the seal decreases. To remedy this deficiency has become known, a thin washer between the seal and the closing part of the valve to arrange made of spring metal, which should spring so far when closing, _ that the later contraction. is balanced.

Die Nachteile dieser Ausführung, daß die Kraft der Federscheibe genau zum Werkstoffverhalten der Dichtung abgestimmt sein muß, 'andernfalls keine befriedigende Wirkung eintritt, daß ferner die Schließ-und Öffnungswege verlängert sind und die Gefahr besteht, daß beim Absperrvorgang nicht genügend weit durchgedreht wird und dann trotz der Federscheibe das Tröpfeln eintritt, werden gemäß der Erfindung in vollkommener Weise dadurch behoben, daß zwischen Ventildichtung und Schließteil ein so ausgeführter Bimetallkörper angeordnet ist, daß er die durch Erwärmung oder Abkühlung am Schließteil eintretenden Längenänderungen kompensiert. Vorzugsweise hat der Bimetallkörper die Ausführung einer oder mehrerer in der Ventilachse liegender Bimetall-Tellerscheiben, deren Dehnmetall auf der Innenseite des Tellers liegt. In dieser Ausführung wird der Teller bei fallender Temperatur höher, kompensiert also die Kontraktion im Ventil. Infolge der automatischen Kompensation aller durch Temperaturschwankungen auftretenden Längenänderungen verhält es sich wie ein aus dehnungsfreiem Werkstoff hergestelltes Ventil. Die Zeichnung veranschaulicht die Erfindung an dem Beispiel eines Ventiloberteiles des Sanitärarmaturenfaches mit stehender Spindel 1 und axial bewegtem Kegelstück 2 mit Anordnung von zwei Stück solcher Bimetall-Tellerscheiben 3, die in einer hülsenartigen Eindrehung 4 des Kegelstückes über der Ventildichtung 5 angeordnet sind. Die Ventildichtung 5 ist etwa mit der Mutter 6 in dem Metalleinsatz 7 befestigt, der seinerseits in der hülsenförmigen Eindrehung 4 geführt und vorteilhaft durch die nach innen gebördelteHülsenkante 8 am Platze gesichert ist.The disadvantages of this design is that the force of the spring washer is accurate must be matched to the material behavior of the seal, otherwise not a satisfactory one The effect occurs that furthermore the closing and opening paths are lengthened and the There is a risk that the shut-off process will not turn sufficiently far and then despite the spring washer the dripping occurs, according to the invention in completely corrected by the fact that between valve seal and closing part a so designed bimetal body is arranged that it by heating or Cooling off occurring changes in length on the closing part. Preferably the bimetallic body has the design of one or more lying in the valve axis Bimetal plate washers, the expanded metal of which lies on the inside of the plate. In this version, the plate is compensated higher when the temperature drops so the contraction in the valve. As a result of the automatic compensation of all through Changes in length that occur due to temperature fluctuations behave like an off valve made of non-stretch material. The drawing illustrates the Invention using the example of an upper valve part of the sanitary fittings compartment standing spindle 1 and axially moved cone piece 2 with an arrangement of two pieces such bimetallic plate washers 3, which are in a sleeve-like recess 4 of the cone piece are arranged above the valve seal 5. The valve seal 5 is approximately with the Nut 6 fastened in the metal insert 7, which in turn is in the sleeve-shaped Notch 4 guided and advantageously through the inwardly beaded sleeve edge 8 is secured in place.
