Kugelhähne werden in Rohrleitungen verwendet, um Flϋssigkeitsströme abriegeln zu können.Ball valves are used in pipelines to block fluid flows.
Gemäß dem Stand der Technik verfügen Kugelhähne über Spindeln mit Mitnehmerstegen, welche in eine korrespondierende Führung eines Dichtkörpers eingreifen. Gemäß dem Stand der Technik werden Spindeln durch das Innere eines Gehäuseteils in einen Spindelsitz eingeführt, bis sie an einen Anschlag anstoßen. Dann wird der korrespondierende Dichtkörper in das Gehäuse des Kugelhahns eingeschoben, so dass der Mitnehmersteg in die Führung eingreift. Daraufhin wird das Gehäuse verschlossen. Diese Montage ist relativ aufwändig.According to the prior art, ball valves have spindles with driving webs, which engage in a corresponding guide of a sealing body. In the prior art, spindles are inserted through the interior of a housing part into a spindle seat until they abut against a stop. Then, the corresponding sealing body is inserted into the housing of the ball valve, so that the carrier web engages in the guide. Then the housing is closed. This assembly is relatively expensive.
Aufgabe der vorliegenden Erfindung ist es daher, einen Kugelhahn zu konzipieren, welcher einfacher montierbar ist, und dennoch ein sicherer unverlierbarer Eingriff des Mitnehmer¬ stegs in die korrespondierende Führung des Dichtkörpers gewährleistet ist. Gemäß den Merkmalen des unabhängigen Anspruchs 1 wird dies dadurch erreicht, dass die Spindel über einen Mitnehmersteg verfügt, welcher hintergreifend in eine korrespondierende Führung eines kugelförmigen Dichtkörpers eingreift.Object of the present invention is therefore to design a ball valve, which is easier to install, and yet a safe captive engagement of Mitnehmer¬ web is ensured in the corresponding guide of the sealing body. According to the features of independent claim 1, this is achieved in that the spindle has a carrier web, which engages behind a corresponding engagement in a corresponding guide of a spherical sealing body.
Gemäß den Merkmalen des abhängigen Anspruchs 2 weist der Mitnehmersteg die Form eines Schwalbenschwanzes, T-Stücks oder einer Ellipse auf.According to the features of the dependent claim 2, the entrainment bar in the form of a dovetail, T-piece or an ellipse.
Gemäß den Merkmalen des abhängigen Anspruchs 3 ist der Dichtkörper innerhalb des Gehäuses in Gleit- und Dichtschalen gelagert.According to the features of the dependent claim 3, the sealing body is mounted within the housing in sliding and sealing shells.
Gemäß den Merkmalen des Verfahrensanspruchs 4 wird der Kugelhahn dadurch hergestellt, dass die Spindel von außen in einen Spindelsitz eines ersten Gehäuseteils eingeführt wird, der kugelförmige Dichtkörper derart in das erste Gehäuseteil eingeführt wird, dass der Mitnehmersteg der Spindel in die korrespondierende Führung des Dichtkörpers eingreift und ein zweites Gehäuseteil mit dem ersten Gehäuseteil verbunden wird.According to the features of the method claim 4, the ball valve is produced in that the spindle is inserted from the outside into a spindle seat of a first housing part, the spherical sealing body is inserted into the first housing part such that the Mitnehmersteg the spindle engages in the corresponding guide of the sealing body and a second housing part is connected to the first housing part.
Die Erfindung wird nun anhand der Figuren im Detail erläutert.The invention will now be explained in detail with reference to the figures.

Fig. 2 einen erfindungsgemäßen Kugelhahn,2 shows a ball valve according to the invention,
Fig. 3 bis 5 spezielle Ausführungsformen der Spindeln. Figur 1 zeigt einen Kugelhahn 1 mit einer Spindel 2, einem kugelförmigen Dichtkörper 3 sowie zwei Gehäuseteilen 4, 5 gemäß dem Stand der Technik. Die Spindel befindet sich innerhalb eines Spindelsitzes 12 und wird mittels zweier Dichtungen 10 gegenüber dem Gehäuse 4, 5 abgedichtet. Ferner verfügt die Spindel 2 über einen rechteckigen Mitnehmersteg 7, welcher in eine rechteckige Führung 8 des kugelförmigen Dichtkörpers 3 eingreift. Der kugelförmige Dichtkörper 3 verfügt ferner über eine Durchgangsleitung 6.Fig. 3 to 5 specific embodiments of the spindles. Figure 1 shows a ball valve 1 with a spindle 2, a spherical sealing body 3 and two housing parts 4, 5 according to the prior art. The spindle is located within a spindle seat 12 and is sealed by means of two seals 10 relative to the housing 4, 5. Furthermore, the spindle 2 has a rectangular carrier web 7, which engages in a rectangular guide 8 of the spherical sealing body 3. The spherical sealing body 3 further has a passage line 6.
Figur 2 zeigt einen erfindungsgemäßen Kugelhahn 1 mit zwei Gehäusehälften 4, 5, einem kugelförmigen Dichtkörper 3 mit Durchgangsleitung 6 sowie einer Spindel 2. Die Spindel 2 sitzt innerhalb eines Spindelsitzes 12 im Gehäuseteil 4. Sie verfügt über einen Mitnehmersteg 11 in Form eines Schwalbenschwanzes, welcher in eine korrespondierende Führung 13 des kugelförmigen Dichtkörpers 3 eingreift. Die Spindel 2 ist ferner über eine Dichtung 10 gegenüber dem Gehäuseteil 4 abgedichtet. Ein zweites Gehäuseteil 5 ist mit dem ersten Gehäuseteil 4 verschraubt. Hierdurch ist der kugelförmige Dichtkörper 3 derartig in dem Kugelhahn 1 gelagert, dass er nicht mehr entweichen kann. Ferner befindet sich der kugelförmige Dichtkörper 3 innerhalb zweier Gleit- und Dichtschalen 9, die vorzugsweise aus Teflon gefertigt sind, sodass der kugelförmige Dichtkörper 3 gegenüber den Gehäuseteilen 4, 5 einerseits dicht gelagert ist, andererseits bei einer Drehbewegung eine geringe Reibung entsteht.Figure 2 shows a ball valve 1 according to the invention with two housing halves 4, 5, a spherical sealing body 3 with through-line 6 and a spindle 2. The spindle 2 is seated within a spindle seat 12 in the housing part 4. It has a Mitnehmersteg 11 in the form of a dovetail, which engages in a corresponding guide 13 of the spherical sealing body 3. The spindle 2 is further sealed by a seal 10 relative to the housing part 4. A second housing part 5 is screwed to the first housing part 4. As a result, the spherical sealing body 3 is mounted in the ball valve 1 such that it can no longer escape. Further, the spherical sealing body 3 is within two sliding and sealing shells 9, which are preferably made of Teflon, so that the spherical sealing body 3 against the housing parts 4, 5 on the one hand tightly mounted, on the other hand, a slight friction occurs during a rotary motion.
Bei der Montage eines derartigen erfindungsgemäßen Kugelhahns 1 wird zunächst eine Gehäusehälfte 4 mit einer Gleit- und Dichtschale 9 versehen. Anschließend wird die Spindel 2 mitsamt Dichtung 10 von außen in den Spindelsitz 12 bis zu einem Anschlag eingeführt. Nun wird der kugelförmige Dichtkörper 3 derartig in das Gehäuseteil 4 eingeführt, dass der Mitnehmersteg 11 der Spindel 2 in die korrespondierende Führung 13 des kugelförmigen Dichtkörpers 3 eingreift. Nun wird die zweite Gehäusehälfte 5, in der sich ebenfalls eine Gleit- und Dichtschale 9 befindet, mit der ersten Gehäusehälfte 4 derart verschraubt, dass der kugelförmige Dichtkörper 3 dicht innerhalb des Kugelhahnes 1 gelagert ist. Wird nun die Spindel 2 verdreht, so wird über den Mitnehmersteg 11 und die korrespondierende Führung 13 der kugelförmige Dichtkörper 3 ebenfalls verdreht, wodurch je nach Stellung durch die Durchgangsleitung 6 Wasser strömen kann oder nicht.When mounting such a ball valve 1 according to the invention, first a housing half 4 is provided with a sliding and sealing shell 9. Subsequently, the spindle 2 together with the seal 10 is introduced from the outside into the spindle seat 12 up to a stop. Now, the spherical sealing body 3 is inserted into the housing part 4 in such a way that the carrier web 11 of the spindle 2 engages in the corresponding guide 13 of the spherical sealing body 3. Now, the second housing half 5, in which there is also a sliding and sealing shell 9, screwed to the first housing half 4 such that the spherical sealing body 3 is mounted tightly within the ball valve 1. If now the spindle 2 is rotated, then the spherical sealing body 3 is likewise rotated via the entrainment web 11 and the corresponding guide 13, whereby, depending on the position, water can flow through the through-line 6 or not.
