Description

DEUTSCHESGERMAN

Bei der Lagerung leichtverdunstender Flüssigkeiten werden zur Verringerung der Atmungsverluste Über- und Unterdruckventile angeordnet.When storing liquids that evaporate easily, over- and vacuum valves arranged.

Da die meist als stehende Zylinder ausgeführten Großtanke nur geringe Betriebsdrücke gestatten, müssen solche Ventile bei kleinsten Druckintervallen (beispielsweise 50 bis 200 mm WS) ansprechen. Sie müssen also sehr zuverlässig arbeiten, was bei den bislang bekanntgewordenen Ventilkonstruktionen nicht der Fall ist.Since the large tanks, which are usually designed as upright cylinders, only allow low operating pressures, such valves must respond at the smallest pressure intervals (for example 50 to 200 mm water column). she So they have to work very reliably, which is not the case with the valve designs that have become known up to now the case is.

Weiter muß dafür gesorgt werden, daß im Winter der Ventilteller an seinem Ventilsitz oder in seiner Ventilführung nicht festklebt oder festfriert, da hierdurch der zuverlässige Unter- bzw. Überdruck überschritten wird und damit der Behälter zerstört werden kann.It must also be ensured that in winter the valve plate on its valve seat or in its Valve guide does not stick or freeze, as the reliable underpressure or overpressure is exceeded as a result and thus the container can be destroyed.

Man hat versucht, ein Festfrieren des Ventiltellers oder der Ventilführung zu verhindern, indem man den Ventilsitz mit einer sogenannten Messerschneide oder die Ventilführung als Dreieckschneide ausgebildet hat. Hierdurch wird die Gefahr des Festfrierens wohl herabgesetzt, aber nicht beseitigt.Attempts have been made to prevent the valve head or valve guide from freezing by using the Has designed the valve seat with a so-called knife edge or the valve guide as a triangular edge. This may reduce the risk of freezing, but it does not eliminate it.

Es wurden auch Versuche unternommen, den Ventilteller selbst aus Kunststoff herzustellen oder durch Aufspritzen einer Kunststoffschicht die Gefahr des Festfrierens zu verhüten. Aber auch diese Lösung hat bisher zu keiner Befriedigung geführt.Attempts have also been made to manufacture the valve disc itself from plastic or to prevent the risk of freezing by spraying on a plastic layer. But also this solution has not yet led to any satisfaction.

Man verwendet auch Membranventile, welche zwar anfangs gut arbeiten, aber mit zunehmender Betriebsdauer verspröden, rissig werden und somit eine einwandfreie Betriebsweise beeinträchtigen.Diaphragm valves are also used, which work well at the beginning, but as the service life increases become brittle, crack and thus impair proper operation.

Die nachstehend beschriebene Erfindung beseitigt die bisher bestehenden Mängel.The invention described below overcomes the heretofore existing shortcomings.

Die Frostsicherheit wird hierbei durch Verwendung eines wasserabweisenden Werkstoffes erzielt, welcher gleichzeitig auch korrosionsfest und bis zu gewissen Grenzen wärmefest ist, und zwar durch Anordnung eines Kunststoff-Ventilsitzes, z. B. aus Fluon, Teflon od. ä. Um die wasserabweisende Wirkung des Ventilsitzes zu erhöhen und einen flächenmäßig günstigeren Anpressungsdruck durch Eigengewicht des Ventiltellers zu erzielen, erhält zweckmäßig der Ventilsitz ein schneidenförmiges Profil.The frost protection is achieved here by using a water-repellent material, which at the same time is also corrosion-resistant and heat-resistant up to certain limits, namely by arrangement a plastic valve seat, e.g. B. Fluon, Teflon od. Ä. To the water-repellent effect of the valve seat to increase and a more favorable contact pressure in terms of area due to the weight of the valve disk to achieve, the valve seat is expediently given a blade-shaped profile.

Es ist ferner bekannt, daß metallische Ventilteller bei großem Durchmesser gewichtsmäßig für kleinste betriebliche Ansprechdrücke sehr ungünstig sind. Ferner ist die Abdichtung des großen Ventiltellers bereits durch geringste Verschmutzung oder durch Staubteilchen immer in Frage gestellt. Die Erfindung beseitigt diese Nachteile, indem sie den Ventilteller -50 aus spezifisch leichtem, korrosionsbeständigem und weicherem Kunststoff vorsieht, so daß bereits bei geringsten Ansprechdrücken eine gute Abdichtung zwischen Ventilsitz und Ventilteller erreicht wird.It is also known that metal valve disks with large diameters in terms of weight for the smallest operational response pressures are very unfavorable. Furthermore, the sealing of the large valve disk always called into question by the slightest pollution or by dust particles. The invention eliminates these disadvantages by making the valve disc -50 from specifically light, corrosion-resistant and Provides softer plastic, so that a good seal even with the lowest response pressures is reached between the valve seat and valve disc.

Die Ventilteller-Schaftführung ist ebenfalls aus wasserabweisendem und korrosionsfestem Kunststoff ausgebildet, um ein Festsetzen durch Frost zu verhüten und gewichtsmäßig günstigere Bedingungen zu erzielen.The valve disk shaft guide is also made of water-repellent and corrosion-resistant plastic designed to prevent freezing-up and to conditions that are more favorable in terms of weight achieve.

Nachstehend eine kurze Beschreibung des Erfmdungsgegenstandes: Below is a brief description of the subject matter of the invention:

In einem Metall-Ventilgehäuse 1 wird der korrosionsbeständige Paßring α mit dem fest eingearbeiteten, wasserabweisenden, korrosions- sowie wärmefesten Kunststoff b im Paßsitz eingesetzt.In a metal valve housing 1, the corrosion-resistant fitting ring α with the permanently incorporated, water-repellent, corrosion-resistant and heat-resistant plastic b is used in a snug fit.

In einem Metall-Ventilteller 2 wird in gleicher Form der Paßring c mit dem fest eingearbeiteten, korrosionsfesten, aber weicheren Kunststoff d eingedrückt. In a metal valve disk 2, the fitting ring c with the firmly incorporated, corrosion-resistant, but softer plastic d is pressed in in the same form.

Die Ventiltellerführung e erhält eine zylindrische wasserabweisende, korrosionsbeständige und wärmefeste Kunststoffhülse sowie Kunststoffschaft.The valve disk guide e is given a cylindrical, water-repellent, corrosion-resistant and heat-resistant plastic sleeve and plastic shaft.
