Description
Zur Abdichtung der Ventilspindel, insbesondere an sogenannten Stahlflaschenventilen, welche Gase unter hohem Überdrucke enthalten, wird ein Gummiring angewendet, welcher die Ventilspindel umgibt und deren Hub mitmacht, solange derselbe in seiner Elastizität nicht nachgelassen hat. Tritt dagegen im Laufe der Zeit eine Verminderung der Elastizität ein, so macht der GummiringFor sealing the valve spindle, especially on so-called steel cylinder valves, which contain gases under high overpressure, a rubber ring is used, which surrounds the valve spindle and its Hub participates as long as the same has not decreased in its elasticity. Kick it a reduction in elasticity over time, this is what the rubber ring does
ίο aus eigener Elastizität den Spindelhub nicht mehr vollständig mit, und infolgedessen treten alsdann Undichtigkeiten an der Spindel auf, die zu Betriebsstörungen, Materialverlust und zu großen Sach- und Personenschäden führen können.ίο not the spindle stroke due to its own elasticity more completely with it, and as a result, leaks occur on the spindle leading to operational disruptions, loss of material and serious damage to property and personal injury being able to lead.
Gegenstand dieser Erfindung ist eine Abdichtung an den Ventilspindeln solcher Ventile, bei welchen der vorerwähnte Übelstand dadurch beseitigt ist, daß der Betriebsdruck direkt so auf den Dichtring einwirkt, daß er denselben während des Spindelhubes gegen alle Anliegeflächen anpreßt und ihn somit in seiner Elastizität unterstützt.The object of this invention is a seal on the valve stems of such valves, in which the aforementioned drawback is eliminated that the operating pressure acts directly on the sealing ring that it counteracts the same during the spindle stroke presses all contact surfaces and thus supports it in its elasticity.
In der Zeichnung ist ein solches Ventil in zwei Ausführungsformen dargestellt.In the drawing, such a valve is shown in two embodiments.
Abb. ι zeigt ein Ventil mit Obersitz, d. h. der Ventilkegel 4 drückt mit seiner Dichtung 5 von oben auf den Ventilsitz über der Zustrombohrung 2.Fig. Ι shows a valve with a top seat, d. H. the valve cone 4 presses with its seal 5 from above onto the valve seat above the inflow bore 2.
Abb. 2 zeigt ein sonst gleiches Ventil, jedoch mit Untersitz, d. h. der Ventilkegel wird mit der Dichtung 5 von unten gegen den Ventilsitz in der Zustrombohrung 2 herangezogen. Fig. 2 shows an otherwise identical valve, but with a bottom seat, i.e. H. the valve cone will pulled with the seal 5 from below against the valve seat in the inflow bore 2.
Beide Beispielsformen haben bei 8 eine seitliche Abflußbohrung, welche bei geöffnetem Ventil bei der Dichtung 5 in direkter offener Verbindung mit der Zustrombohrung 2 steht, also mit der dort angeschlossenen Gasflasche. Both example forms have a lateral drain hole at 8, which when open Valve at the seal 5 in direct open connection with the inflow bore 2 stands, i.e. with the gas bottle connected there.
Die Bewegung des Ventilkegels 4 geschieht zwangsläufig in bekannter Weise durch Drehen am Handrade sowohl für das Schließen wie auch für das Öffnen des Ventils bei 5.The movement of the valve cone 4 inevitably takes place in a known manner by turning on the handwheel for both closing and opening the valve at 5.
Der Drehkörper mit dem Handrade ist nach außen nicht abgedichtet; es liegt lediglich eine Abdichtung zwischen Ventilkegel 4 •und dem Gehäuse 3, und zwar ein Dichtring 9 in Form eines Schlauchabschnittes, der mit seinen beiden Enden tief in Ringnuten mit trapezförmigem Querschnitt des Gehäuses und des Ventilkegels eingelagert ist. Da der Dichtring leinen rechteckigen Querschnitt hat, verbleibt ihm auch bei geschlossenem Ventil infolge des größeren Querschnittes der Ringnut innerhalb derselben eine gewisse Bewegungsfreiheit, so daß er sich innerhalb der Nut verkürzen und verdicken bzw. verlängern und verdünnen kann, ohne über seine Elastizitätsgrenze hinaus beansprucht zu werden. Infolgedessen kann er die Bewegung des Ventilkegels, also dessen Hub mitmachen, ohne daß er in einer seiner Stellungen die feste Anlage gegen den Boden der Ringnuten verliert.The rotating body with the handwheel is not sealed to the outside; it just lies a seal between the valve cone 4 • and the housing 3, namely a sealing ring 9 in the form of a hose section with both ends deep in annular grooves trapezoidal cross-section of the housing and the valve cone is incorporated. Because the sealing ring l has a rectangular cross-section, it remains even when the valve is closed due to the larger cross-section of the annular groove within the same a certain freedom of movement, so that it shortens and thickens or lengthen within the groove and can be thinned without being stressed beyond its elastic limit. As a result, he can participate in the movement of the valve cone, i.e. its stroke, without him in one of his positions the firm contact against the bottom of the annular grooves loses.
Wesentlich ist, daß die Ringnuten den Dichtring an beiden Enden umschließen. Die Ringnuten sind so ausgebildet, daß sich die äußere, zwischen Ventilkegel und Gehäuse außerhalb des Dichtringes liegende Fuge bei der Bewegung des Ventilkegels nicht öffnet.It is essential that the annular grooves enclose the sealing ring at both ends. the Annular grooves are designed so that the outer, between valve cone and housing The joint outside the sealing ring does not open when the valve cone moves.
Die beiden Körper 3 und 4 passen an dieser Fuge schließend ineinander und bewegen sich teleskopartig zueinander. Diese äußere Dichtfuge verändert somit ihre Durchlaßöffnung während der Bewegung des Ventilkegels überhaupt nicht. Die innere, der Druckseite zugekehrte Fuge zwischen den Körpern 3 und 4 kann sich bei der Bewegung des Ventilkegels öffnen (Abb. 2), was aber nicht erforderlich ist (Abb. 1).The two bodies 3 and 4 fit into each other at this joint and move telescope to each other. This outer sealing joint thus changes its passage opening not at all during the movement of the valve plug. The inner, the pressure side the facing joint between the bodies 3 and 4 can open when the valve cone moves (Fig. 2), but it does not is required (Fig. 1).
