Title (EN) CRYOGENIC SHUT-OFF VALVE
(FR) VANNE D'ARRÊT CRYOGÉNIQUE
(DE) KRYOGENES ABSPERRVENTIL
Abstract:
(EN) The invention relates to a valve (10) for use in low temperature regions, in particular below 40 °C, preferably below 100 °C, particularly preferable below 150 °C, comprising a flow channel (1), and a closing element (3) that is adjustable relative to a valve seat (2) in the flow channel (1), by way of which a defined flow cross-section can be freed for the medium flowing in the flow channel (1). The valve (10) comprises a valve gasket (5), which in a closed state of the valve (10) seals the flow channel (1) between valve seat (2) and closing element (3). According to the invention, the valve gasket (5) is made of a polyketone.
(FR) L'invention concerne une vanne (10) destinée à être utilisée à de basses températures, en particulier en dessous de -40° C, de préférence en dessous de -100° C, particulièrement de préférence en dessous de -150° C, ladite vanne comprenant un canal d'écoulement (1) et un élément de fermeture (3) pouvant être relativement déplacé à l'encontre d'un siège de vanne (2), élément de fermeture par lequel une section transversale d'écoulement définie destinée au fluide en écoulement dans le canal d'écoulement (1) peut être libérée, la vanne (10) comprenant un élément d’étanchéité de vanne (5), lequel assure l'étanchéité du canal d'écoulement (1) entre le siège de vanne (2) et l'élément de fermeture (3), lorsque la vanne est à l'état fermé (10), Selon l'invention, l’élément d’étanchéité de vanne (5) se compose d'une polycétone.
(DE) Die Erfindung betrifft ein Ventil (10) zum Einsatz im Tieftemperaturbereich, insbesondere unter -40 °C, vorzugsweise unter -100 °C, besonders bevorzugt unter -150 °C, umfassend einen Strömungskanal (1) und ein in dem Strömungskanal (1) entgegen einem Ventilsitz (2) relativ verstellbares Schließelement (3), mit dem ein definierter Strömungsquerschnitt für das im Strömungskanal (1) strömende Medium freigebbar ist, wobei das Ventil (10) eine Ventildichtung (5) umfasst, die im geschlossenen Zustand des Ventils (10) den Strömungskanal (1) zwischen Ventilsitz (2) und Schließelement (3) abdichtet. Erfindungsgemäß ist vorgesehen, dass die Ventildichtung (5) aus einem Polyketon besteht.
