Abstract

A ball shut-off valve is welded into a pipe. The valve active components such as ball and seal are inserted vertically through an opening (8) in the ball housing (1). A control organ (15) rotates and controls a passage (16) with a ball plug (2) and a housing wall (10) with an inlet and outlet with sealing elements (4,5,6). The ball plug is part of a unit (11) and is connected to a half shell (3) by means of screws (12).

Description

Die Erfindung beinhaltet einen Absperrkugelhahn, welcher in eine Rohrleitung eingeschweißt werden kann und die Verschleißteile wie Schaltkugel und Dichtelemente vertikal über eine Öffnung im Kugelhahngehäuse eingebracht werden können.The invention includes a shut-off ball valve, which in a pipeline can be welded and the wearing parts such as switching ball and Sealing elements introduced vertically through an opening in the ball valve housing can be.

Ein Hauptanliegen der Neuerung ist, dass Flanschverbindungen, wie bei herkömmlichen Kugelhähnen üblich, vermieden werden und somit der TA- Luftforderung entsprochen wird (Umweltbelastung).A main concern of the innovation is that flange connections, as with conventional ball valves, can be avoided and thus the TA- Air demand is met (environmental pollution).

Ähnliche Ausführungen sind bekannt (P 220 2097.9, GM 80 11085), wobei die Schaltkugel bzw. die Dichtelemente in eine konische Ausnehmung des Gehäuses eingebracht werden, wobei eine Fixierung des Durchganges (Gehäuse/Schaltkugel) und eine angefederte Abdichtung im Durchgang nicht gegeben sind.Similar designs are known (P 220 2097.9, GM 80 11085), the Switch ball or the sealing elements in a conical recess of the Housing are introduced, with a fixation of the passage (Housing / switching ball) and a spring-loaded seal in the passage given are.

Bei der Erfindung wird eine in sich verschraubte Einheit in eine zylinderische Ausnehmung des Kugelhahngehäuses eingesetzt und durch eine ca. 90° Dehnung in die Durchgangsstellung gebracht. Hierbei werden die Dichtelemente federnd vorgespannt.In the invention, a screwed unit in a cylindrical Recess of the ball valve housing inserted and through an approx. 90 ° Elongation brought into the open position. Here, the sealing elements spring-loaded.

In der folgenden Beschreibung wird der Einschweißkugelhahn anhand von 5 Zeichnungen näher beschrieben:In the following description, the weld-in ball valve is based on FIG. 5 Drawings described in more detail:

Fig. 1 Längsschnitt durch den Einschweißkugelhahn in geschlossener Stellung. Fig. 1 longitudinal section through the welding ball valve in the closed position.

Fig. 2 Längsschnitt Fig. 2 longitudinal section

Fig. 3 Querschnitt Fig. 3 cross section

Fig. 4 Darstellung in ungespanntem Zustand. Fig. 4 representation in the untensioned state.

Fig. 5 Darstellung in Durchgangsstellung mit vorgespannten Dichtelementen. Fig. 5 representation in the through position with prestressed sealing elements.

Der Einschweißkugelhahn besteht aus einem einteiligen Gehäuse (1), welches hauptsächlich zum Einschweißen in Rohrleitungen vorgesehen ist.The welding ball valve consists of a one-piece housing ( 1 ), which is mainly intended for welding in pipelines.

Die Schaltkugel (2) wird als Einheit (11) zusammen mit den Schalen(3) und den Dichtungen (4), (5), (6) in eine Ausnehmung (7) des Gehäuses (1) eingebracht, welche im rechten Winkel zum Durchgang (8) des Gehäuses (1) eine Erweiterung (9) gegenüber den Dichtflächen (10), Fig. 4, aufweist.The switching ball ( 2 ) is introduced as a unit ( 11 ) together with the shells ( 3 ) and the seals ( 4 ), ( 5 ), ( 6 ) into a recess ( 7 ) in the housing ( 1 ), which is at a right angle to Passage ( 8 ) of the housing ( 1 ) has an extension ( 9 ) relative to the sealing surfaces ( 10 ), Fig. 4.

Hierdurch ist es möglich, dass die Dichtringe (4), (5), (6), ungespannt eingesetzt werden (Fig. 4) und erst durch Drehen der Einheit (11) in die Durchgangsstellung (Fig. 5) eine Abdichtung an den Dichtflächen (10) bewirkt wird.This makes it possible for the sealing rings ( 4 ), ( 5 ), ( 6 ) to be inserted without tension ( FIG. 4) and only for the sealing surfaces to be sealed by turning the unit ( 11 ) into the through position ( FIG. 5) ( 10 ) is effected.

Zum Herausnehmen der Einheit (11) wird diese in die Ausgangsstellung gedreht (Fig. 4).To remove the unit ( 11 ), it is rotated into the starting position ( FIG. 4).

Als Festpunkte zum Drehen der Einheit (11) sind die Köpfe der Verbindungsschrauben (12) vorgesehen, welche in Ausnehmungen (13) des Gehäusedeckels (14) integriert sind.The heads of the connecting screws ( 12 ) are provided as fixed points for rotating the unit ( 11 ) and are integrated in recesses ( 13 ) in the housing cover ( 14 ).

Die Auf-Zu-Stellung der Schaltkugel(2) wird durch die im Gehäusedeckel (14) nach außen geführte Schaltwelle (15) bewirkt.The open-close position of the switching ball ( 2 ) is brought about by the switching shaft ( 15 ) guided outwards in the housing cover ( 14 ).
