Description

Die Neuerung betrifft ein Lager für ein Kugelküken eines Kugelhahnes das das Kugelküken mit Ausnahme seiner Durch­ bohrung und einer Durchlaßöffnung für ein Bedienungsorgan völlig umgibt und aus zwei Teilen besteht, von denen min­ destens eine Schale im Bereich des Ein- und Auslasses ab­ dichtend gegen das Kugelküken gedrückt ist. Jeweils im Be­ reich des Ein- und Auslasses des Kugelkükens ist im Bereich der Schalen, welche aus Kunststoff bestehen, ein abriebfes­ ter Ring integriert. Dieser Ring besteht vorzugsweise aus Metall, Kunststoff oder Keramik und hat die Aufgabe, bei ab­ rassiven Fördermedien den Verschleiß der Dichtungen zu min­ dern. Ein ähnlicher Kugelhahn ist bekannt (DE 28 07 913 C2). Er ist zwar hohlraumfrei ausgebildet, hat aber den Nachteil, daß er keinen zusätzlichen verschleißfesten Ring am Ein- und Auslaß des Kugelkükens hat, wie es die Neuerung darstellt. Der Neuerung liegt die Aufgabe zugrunde, gegenüber diesem Stand der Technik, die Abdichtung im Kugelhahn-Durchgang zu verbessern.The innovation concerns a bearing for a ball plug Ball valve that the ball chick with the exception of its through bore and a passage opening for an operating element completely surrounds and consists of two parts, of which min preferably a bowl in the area of the inlet and outlet is sealingly pressed against the ball plug. Each in the Be The range of the inlet and outlet of the ball plug is in the area the shells, which are made of plastic, are abrasion-resistant integrated ring. This ring preferably consists of Metal, plastic or ceramic and has the task of ab rassive media to wear the seals to min other. A similar ball valve is known (DE 28 07 913 C2). Although it is free of cavities, it has the disadvantage that that he has no additional wear-resistant ring on the Ball valve outlet has, as it represents the innovation. The innovation is based on the task, compared to this State of the art, the seal in the ball valve passage to improve.

Diese Aufgabe wird durch den gekennzeichneten Patentanspruch gelöst.This object is characterized by the claim solved.
