DIN EN 16447:2014 Edition

Tue, 05 Nov 2024 16:01:23 +0000

Diese Norm beschreibt die allgemeinen Anforderungen an Rückschlagklappen, die zur explo-sionstechnischen Entkopplung verwendet werden. Bei einer Rückschlagklappe zur explosionstechnischen Entkopplung handelt es sich um ein Schutzsystem, das verhindert, dass sich eine Explosion über Verbindungsrohre oder -kanäle in andere Teile der Apparatur oder Anlagenbereiche ausbreitet. Eine Rückschlagklappe zur explosionstechnischen Entkopplung kann die Ausbreitung einer Explosion nur dann stoppen, wenn diese in Gegenrichtung zum üblichen Prozessstrom erfolgt. Sie verhindert nicht die Aus-breitung von Explosionen in Richtung des üblichen Prozessstroms.*Inhaltsverzeichnis
