Description
Die Neuerung betrifft ein Lager für ein Kugelküken eines Kugelhahnes, das das Kugelküken mit Ausnahme seiner Durchbohrung und einer Durchlaßöffnung für ein Bedienungsorgan völlig umgibt und aus drei Teilen besteht, von denen je eine äußere Lagerschale im Bereich des Ein- und Auslasses abdich tend gegen das Kugelküken gedrückt ist.The innovation concerns a bearing for a ball valve of a ball valve, which Ball plug with the exception of its piercing and one Passage opening for an operating element completely surrounds and consists of three parts, one of which is external Seal the bearing shell in the area of the inlet and outlet tend to be pressed against the ball plug.
Ähnliche Kugelhähne sind bekannt (DE-GM 73 33 493, US-PS 30 41 036).Similar ball valves are known (DE-GM 73 33 493, U.S. Patent 30 41 036).
Sie sind zwar hohlraumfrei ausgebildet, haben aber den Nachteil, daß sie keine zusätzliche Abdichtung am Auslaß und Ein laß haben, wie es die Neuerung darstellt.Although they are cavity-free, they have the disadvantage that they no additional sealing at the outlet and on let it be as it represents the innovation.
Der Neuerung liegt die Aufgabe zugrunde, gegenüber diesem Stand der Technik die Abdichtung zwischen Kugel und Lager schalen zu verbessern.The innovation is based on the task, compared to this State of the art the seal between ball and bearing to improve bowls.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.
Die Kugel ist mit Ausnahme des Einlasses und des Auslas ses sowie der Durchdringung des Bedienungsorganes von Kunststoffschalen umgeben, welche am Einlaß und Auslaß des Kugelhahnes zwecks Erhöhung der Abdichtung von vor gespannten Federn mittels Druckringen gegen die Kugel gedrückt werden.The ball is except for the inlet and the outlet ses and the penetration of the operating element of Surround plastic trays, which at the inlet and outlet of the ball valve in order to increase the seal from before tensioned springs by means of pressure rings against the ball be pressed.
Dieses hat den Vorteil, daß ein zum Verderben oder zum Auskristallisieren neigendes Produkt im Kugelhahn keine Hohlräume vorfindet und eine gleichmäßige Anpressung am Auslaß und Einlaß der Kugel die Dichtheit des Kugelhahnes gewähr leistet.This has the advantage that a to spoil or Crystallizing product in the ball valve none Finds voids and an even pressure Ensure the tightness of the ball valve at the outlet and inlet of the ball accomplishes.
Anhand der Zeichnung ist ein Ausführungsbeispiel des Kugelhahnes nach der Neuerung beschrieben.Based on the drawing is an embodiment of the Ball valve described after the innovation.
Die Kugel 10 des dargestellten Kugelhahnes ist mit einer durchgehenden Bohrung 11 versehen. Um die Kugel 10 über ein Bedienungsorgan 12 in die Durchlaß- und Sperrstellung drehen zu können, ist die Kugel 10 durch die Ausnehmung 13 kraftschlüssig mit dem Bedienungsorgan 12 verbunden. Das die Kugel 10 umgebende Gehäuse ist in der Zeichnung als Block- und Ausführung dargestellt. Andere Gehäusearten sind möglich.The ball 10 of the ball valve shown is provided with a through bore 11 . In order to be able to turn the ball 10 into the passage and blocking position via an operating member 12 , the ball 10 is non-positively connected to the operating member 12 through the recess 13 . The housing surrounding the ball 10 is shown in the drawing as a block and execution. Other types of housings are possible.
Wenn die aus Kunststoff bestehenden Lagerschalen 14, 15, 16 mit der Kugel 10 in dem Gehäuse angebracht sind, bilden die Kugeloberflächen und die Lagerschalen eine enganlie gende Verbindung.If the plastic bearing shells 14, 15, 16 are attached to the ball 10 in the housing, the ball surfaces and the bearing shells form a close connection.
Durch das Einlegen des Druckringes 17 und der Tellerfeder 18 sowie das Zusammenschrauben des Hahnes wird bedingt durch die vorgespannte Tellerfeder mittels des Druckringes und des umlaufenden Einstiches 19 oberhalb des Druckringes eine nahezu gleichbleibende Anpressung des hier befind lichen Lagerschalenteiles auf die Oberfläche der Kugel bewirkt.By inserting the pressure ring 17 and the plate spring 18 and screwing the tap together, the pretensioned plate spring by means of the pressure ring and the circumferential groove 19 above the pressure ring causes an almost constant contact pressure of the bearing shell part located here on the surface of the ball.
Hierdurch wird eine Abdichtung am Ein- und Austritt der Kugel sowie eine Überdeckung der restlichen Kugelober fläche mit Ausnahme des Durchganges des Bedienungsorganes und der Bohrung gewährleistet.This creates a seal at the inlet and outlet of the Ball and an overlap of the remaining ball top area with the exception of the passage of the operating element and the bore guaranteed.
