Abstract

The aim of the invention is that a bearing for a spherical plug of a ball valve should be provided at the inlet and outlet of the through hole with respective abrasion-resistant sealing rings which are integrated into plastic shells. This allows the use of a clearance-free ball valve for media containing abrasive or fibrous admixtures.

Description

Die Erfindung bezieht sich auf einen aus einem einteiligen Gehäuse und einer geteilten Kugel bestehenden Kugelhahn. Durch die geteilte Kugel wird erreicht, daß in einem einteiligen Gehäuse die Schaltkugel durch eine Öffnung 20 im Gehäuse zwischen die beiden parallel verlaufenden Dichtungen 17, 18 gebracht werden kann.The invention relates to a ball valve consisting of a one-piece housing and a split ball. The split ball ensures that the switching ball can be brought through an opening 20 in the housing between the two parallel seals 17, 18 in a one-piece housing.

Ähnliche Ausführungen der Kugeleinbringung sind bekannt, wobei die Dichtungen allerdings keilförmig im Gehäuse angebracht sind.Similar designs of the ball insertion are known, whereby however, the seals are wedge-shaped in the housing.

Eine Ausführungsform der Erfindung soll nachstehend anhand der Zeichnung erläutert werden. Der in Gesamtheit mit 10 bezeichnete Kugelhahn besitzt ein aus einer Hohlkugel 11 und zwei eingeschweißten Endstücken 12, 13 bestehendes Gehäuse, das in seinem Innenraum die geteilte Schaltkugel 14, 15, 16 mit den beidseitig von dieser angeordneten Dich­ tungsringen 17, 18 aufnimmt, welche vorzugsweise aus Kunst­ stoff bestehen.An embodiment of the invention will be explained below with reference to the drawing. The ball valve, designated in its entirety by 10 , has a housing consisting of a hollow ball 11 and two welded-in end pieces 12, 13 , which in its interior accommodates the divided switching ball 14, 15, 16 with the sealing rings 17, 18 arranged on both sides thereof, which preferably consist of plastic.

Von der Absperrkugel 14, 15, 16 erstreckt sich quer zum Strömungsweg eine mit der Schaltkugel drehfest verbundene Schalt­ welle 19, durch welche die Offen- oder Zustellung der Schalt­ kugel bewirkt werden kann.From the shut-off ball 14, 15, 16 extends transversely to the flow path with the switching ball rotatably connected switching shaft 19 through which the opening or delivery of the switching ball can be effected.
