Der vollst\u00e4ndig gleiche innere Hohlraum des Ventils bietet einen geraden Str\u00f6mungskanal mit geringem Widerstand f\u00fcr das Medium. Das Hauptmerkmal ist die kompakte Struktur, die einfache Bedienung und Wartung, die Eignung f\u00fcr allgemeine Arbeitsmedien wie Wasser, L\u00f6sungsmittel, S\u00e4uren und Erdgas und auch f\u00fcr Medien mit rauen Arbeitsbedingungen wie Sauerstoff, Wasserstoffperoxid, Methan und Ethylen.<\/p>\n<p>1. Schwimmender Kugelhahn<\/p>\n<p>Die Kugel des Kugelhahns ist schwimmend gelagert. Unter der Einwirkung des Mediendrucks kann die Kugel eine gewisse Verschiebung erzeugen und fest auf die Dichtfl\u00e4che des Auslassendes dr\u00fccken, um sicherzustellen, dass das Auslassende abgedichtet ist. Der schwimmende Kugelhahn hat eine einfache Struktur und eine gute Dichtungsleistung, aber die Last der Kugel, die das Arbeitsmedium tr\u00e4gt, wird vollst\u00e4ndig auf den Auslassdichtungsring \u00fcbertragen, so dass es notwendig ist, zu pr\u00fcfen, ob das Dichtungsringmaterial der Arbeitslast des Kugelmediums standhalten kann. Diese Konstruktion ist bei Mittel- und Niederdruckkugelh\u00e4hnen weit verbreitet.<\/p>\n<p>2. Kugelhahn mit Zapfen<\/p>\n<p>Die Kugel des Kugelhahns ist fest und bewegt sich nicht, wenn sie gedr\u00fcckt wird. Der Kugelhahn mit Zapfen ist mit einem schwimmenden Ventilsitz ausgestattet. Nachdem der Ventilsitz den Druck des Mediums aufgenommen hat, bewegt er sich, so dass der Dichtungsring fest auf die Kugel gepresst wird, um die Abdichtung zu gew\u00e4hrleisten. Die Lager sind in der Regel auf dem oberen und unteren Schaft der Kugel installiert, und das Betriebsdrehmoment ist gering, was f\u00fcr Ventile mit hohem Druck und gro\u00dfem Durchmesser geeignet ist. Um das Betriebsdrehmoment des Kugelhahns zu verringern und die Zuverl\u00e4ssigkeit der Dichtung zu erh\u00f6hen, wurden in den letzten Jahren \u00f6lgedichtete Kugelh\u00e4hne entwickelt. Dabei wird ein spezielles Schmier\u00f6l zwischen die Dichtfl\u00e4chen eingespritzt, um einen \u00d6lfilm zu bilden, der die Dichtungsleistung verbessert und das Betriebsdrehmoment reduziert. Es ist besser f\u00fcr Hochdruckkugelh\u00e4hne und Kugelh\u00e4hne mit gro\u00dfem Durchmesser geeignet.<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Ein schwimmend gelagerter Kugelhahn ist ein Ventil mit Vierteldrehung, das eine Kugel zur Steuerung des Fl\u00fcssigkeitsstroms verwendet.

Die Kugel ist im Ventilgeh\u00e4use frei beweglich, so dass sie sich drehen und den Durchflussweg \u00f6ffnen oder schlie\u00dfen kann.
