Description
Kugelsektorventil Die Erfindung betrifft ein Kugelsektorventil, d. h. ein Kugelventil, welches so ausgebildet ist, daß der Ventilkörper lediglich von einem Teil der Kugel gebildet wird.Ball Sector Valve The invention relates to a ball sector valve, i. H. a ball valve which is designed so that the valve body only from part of the sphere is formed.
Herkömmliche Kugelventile weisen einen im wesentlichen sphärischen Ventilkörper (Kugel) mit einem diametral hindurchgehenden Kanal auf. Die Kugel ist um eine zur Kanalachse senkrechte Achse drehbar. In der Öffnungaatellung ist der Einlaß und der Auslaß des Ventilgehäuses durch den Kanal der Kugel verbunden, während die Kugel in der Absperrstellung mit der Kanalachse im rechten Winkel zur gemeinsamen Aehsenlinie des Einlassen und des Auslasses steht und der Durchgang an der Seite des Kanals durch das Material der Kugel abgesperrt wird. Um die Gehäuseöffnungen sind Dichtungsringe angebracht, die an der sphärischen Wandung der Kugel anliegen. wenn das Ventil geschlossen ist, wird die Kugel, welche in der Regel in axialer Richtung etwas beweglich ist, durch den Druck von der Einlaßseite gegen den Dichtungsring an der Auslaßseite gepreßt, so daß die Dichtung lediglich an der kuslaßseite vorhanden ist.Conventional ball valves have an essentially spherical valve body (ball) with a diametrically penetrating channel. The ball can be rotated about an axis perpendicular to the channel axis. In the opening position the inlet and the outlet of the valve housing are connected by the channel of the ball, while in the shut-off position the ball is with the channel axis at right angles to the common axis line of the inlet and the outlet and the passage on the side of the channel through the material the ball is shut off. Sealing rings, which rest against the spherical wall of the ball, are attached around the housing openings. when the valve is closed, the ball, which is movable in the axial direction somewhat usually pressed by the pressure from the inlet side against the sealing ring at the outlet is such that the Seal is only present on the kuslaßseite.
Man hat deshalb vorgeschlagen, den Ventilkörper als eine
"unvollständige KUKe1" auszubilden und damit leichter au machen, indem
lediglich soviel
Gemäß ler Erfindung wird dieses Problem dadurch gelöst, daß der Ventilkörper die Form eines hohlen sphärischen Keiles von genügendem Winkelausmaß zur Absperrung des Auslasses des Ventilgehäuses aufweist und durch einen Ring in Form einer hohlen sphärischen Zone ergänzt ist, die in-der Offenstellung des Ventils den Ventilauslaß ganz oder teilweise umgibt und an einem um diese angeordneten Dichtungsring anliegt. Hierdurch kann man einen einfachen Dichtungsring verwenden und gleichzeitig den Vorteil eines leichten Ventilkörpers beibehalten.According to the invention, this problem is solved in that the valve body the shape of a hollow spherical wedge of sufficient angular extent to be a barrier of the outlet of the valve housing and by a ring in the form of a hollow spherical zone is added, which in-the open position of the valve the valve outlet completely or partially surrounds and rests against a sealing ring arranged around them. This allows you to use a simple sealing ring and at the same time the Maintaining the advantage of a lightweight valve body.
Die beiliegende Zeichnung zeigt eine Ausführungsform der Erfindung. Fig. 1 veranschaulicht das Ventil in Perspektive, wobei das Gehäuse axial geschnitten ist, und Fig. 2 zeigt einen horizontalen Schnitt entlang der Linie II- II in Fig. 1.The accompanying drawing shows an embodiment of the invention. FIG. 1 illustrates the valve in perspective, with the housing being axially sectioned, and FIG. 2 shows a horizontal section along the line II-II in FIG. 1.
Das dargestellte Ventil hat ein Gehäuse, welches aus einem im wesent- lichen zylindrischen Hauptteil 1 besteht, der an einem Ende einen nach innen gerichteten, den Einla9 3 begrenzenden Flansch 2 aufweist und am anderen Ende mit einem ringförmigen Wandstück 4 verschraubt ist, welches den Auslaß 5 des Ventils begrenzt. Zwischen die beiden Gehäuseteile ist ein Dichtungsring 6 eingelegt. Der Gehäuseteil 1 ist mit Gewindelöchern zum Ansohluß an eine Rohrleitung versehen. Das Wandstück 2 weist entsprechen-de (nicht sioht@are) Gewindelöcher auf. The illustrated valve has a housing which consists of a union in essential cylindrical main body 1 having at one end an inwardly directed, the Einla9 3-limiting flange 2 and is screwed at the other end with an annular wall portion 4, which outlet the 5 of the valve is limited. A sealing ring 6 is inserted between the two housing parts. The housing part 1 is provided with threaded holes for connection to a pipeline . The wall piece 2 has corresponding (not sioht @ are) threaded holes.
Der mylindrische Gehäuseteil 1 ist an diametral gegentiberliegenden
Seiten mit Eälsea d, 9 aupbildet, die keasial sind und deren
geaeinsane Lohse in rechten Winkel zur Lohse des ZTliniers
1 verläuft.-Ia diese Hälse sind Etilsen 10, 11 eingasetst,
durch die sich Zapfen 12 und 1; erstrecken,
Der Ring 22 braucht nicht vollständig geschlossen zu sein. bi kann an einer dem Teil 23 diametral gegenüberliegenden Stelle unterbrochen sein. Er soll jedoch wenigstens 2000 des Umfanges des Auslasses umfacre:#, ',iamit der Dichtungsring sicher festgehalten wird.The ring 22 need not be completely closed. bi can be interrupted at a point diametrically opposite the part 23. However, it is to at least 200 0 of the circumference of the outlet umfacre: #, ', iamit the sealing ring is held securely.
Im dargestellten Ausführungebeispiel ist der Ventilkörper als ein Teil einer Kugelschale dargestellt, d.h. sowohl seine inneren als auch seine äußeren Oberfl,;-.chen sind sphärisch. Dies hat den Vorteil, daß das Ventil so leicht wie möglich wird, ist jedoch nicht absolut notwendig. Die Tnnenfläche des Ventilkörpers kann z. B. eine Zylinderflache sein, dir mit dem Rina 22 koaxial ist.In the illustrated embodiment, the valve body is as a Part of a spherical shell shown, i.e. both its inner and outer Surfaces are spherical. This has the advantage that the valve is as light as becomes possible, but is not absolutely necessary. The inner surface of the valve body can e.g. B. be a cylinder surface, you with the Rina 22 is coaxial.
