Description
Die Erfindung betrifft ein Reparaturventil zur Dampfregelung mit doppeltem Sitz und beidseitigen Verschlußkörpern, wobei der Hauptverschlußkörper unmittelbar und zwangläufig und der kugelförmige und um seinen Mittelpunkt drehbare Reparatur-Verschlußkörper mittels des Hauptverschlußkörpers kraftschlüssig gegen den Sitz geführt wird. Der Erfindung liegt die Aufgabe zugrunde, ein Ventil dieser Gattung (Reparaturventil) derart zu gestalten, daß es bei geringem Herstellungsaufwand eine gute und vollständige Abdichtung auch nach längerer Benutzungszeit gewährleistet, also geringen Verschleiß und wenig Wartung garantiert. Das erfindungsgemäße Ventil ist vor allem durch die Vereinigung folgender Merkmale gekennzeichnet:The invention relates to a repair valve for steam control with a double seat and on both sides Closure bodies, the main closure body being immediate and inevitable and the spherical and repair closure body rotatable about its center by means of the main closure body is positively guided against the seat. The invention is based on the object of a valve this To make genus (repair valve) such that there is a good and low manufacturing cost complete sealing guaranteed even after a long period of use, so low wear and tear little maintenance guaranteed. The valve according to the invention is mainly as follows through the combination Features marked:
1. Der Hauptverschlußkörper ist gleichfalls als um ihren Mittelpunkt drehbare Kugel ausgebildet;1. The main closure body is also designed as a ball rotatable about its center;
2. die beiden Verschlußkörper sind an ihren voneinander abgewandten Seiten in Kugelpfannen und an ihren einander zugekehrten Seiten in Ausnehmungen der sternförmig angeordneten Flügel eines Abstandsstückes gelagert;2. the two closure bodies are on their sides facing away from each other in ball sockets and on their facing sides in recesses of the star-shaped arranged wings a spacer mounted;
3. die beiden Verschlußkörper werden in jeder Hubstellung unter Federwirkung in ihren Lagern gehalten. a5 3. The two closure bodies are held in their bearings in each stroke position under the action of a spring. a 5
Es ist für einen einfachen Wasserleitungshahn ohne Reparaturdichtung bereits vorgeschlagen worden, eine Verschlußkugel mit Pfannenfassung anzuwenden, damit die so durch den Strom des abzusperrenden Mediums frei drehbare Verschlußkugel bei jedem erneuten Absperren mit anderen Teilen ihrer Oberfläche auf den Sitz gedrückt wird, so daß der Verschleiß des beweglichen Schließkörpers über die ganze Oberfläche im statistischen Mittel gleichmäßig verteilt und der Verschleiß je Oberflächeneinheit auf ein Mindestmaß herabgedrückt wird. Dabei wurde die Verschlußkugel in ihrer Halterungspfanne gegen Herausfallen allein durch Adhäsionskräfte gehalten, was eine ungewöhnlich genaue Oberflächenbearbeitung der Kugel und der Pfanne sowie einen molekularen Fiüssigkeitsfilm zwischen beiden voraussetzt. Die erste Bedingung erhöht den HerstellungsauRvand so sehr, daß der Fachmann, obwohl ihm auch Reparaturventile mit begrenzt drehbarer Reparaturverschlußkugel bekannt waren, nicht auf den Gedanken korn- *5 men konnte, die an sich schon aufwendige, komplizierte Pfannenhalterung für die Verschlußkugel aufIt has already been proposed for a simple water tap without a repair seal to use a locking ball with a pan socket so that the locking ball, which is freely rotatable by the flow of the medium to be shut off, is pressed onto the seat with other parts of its surface each time it is shut off, so that the wear and tear of the movable closing body is evenly distributed over the entire surface on a statistical average and the wear per surface unit is suppressed to a minimum. The locking ball was held in its holding socket against falling out solely by adhesive forces, which requires an unusually precise surface treatment of the ball and the socket as well as a molecular liquid film between the two. The first condition increases the HerstellungsauRvand so much so that the skilled person, although he also repair valves with limited swivel repair closing ball were known, not grain-the idea * 5 could men who have been consuming in itself, complex pan holder for the closure ball on

formschlüssig gekoppelt werden können, ohne beide ihre freie Drehbarkeit zu verlieren. Dies erreicht die Erfindung in verblüffend einfacher Weise durch die kraft- und formschlüssige Zwischenschaltung eines bei einem Rückschlagventil mit nur einem beweglichen Schließkörper bekanntgewordenen Abstandsstückes, welches in der erfindungsgemäßen Anwendung nicht nur für eine kongruente, paßgenaue Axialbewegung beider Verschlußkugeln sorgt, sondern auch die Schließkraft der federbelasteten Reparaturverschlußkugel dazu verwendet, um beide Kugeln gleichzeitig leicht auf ihre jeweiligen Pfannenführungsbleche zu drücken, so daß die Kugeln in keiner Betriebsstellung des Ventils aus den Pfannenflächen fallen können, ohne daß es aber erforderlich ist, die Oberflächen der Kugeln und der Pfannen so genau, zu bearbeiten, daß. eine, nennenswerte Adhäsionskraft „erhalten wird, und ohne" daß es erforderlich ist, zur , Sicherstellung des diese. .Haftung ermöglichenden molekularen Flüssig-keitsfilmes das Ventil ausschließlich als Wasserhahn" zu betreiben. Es war also nur bekannt, daß man entweder auf die vorteilhafte allseitige Drehbarkeit der Verschlußkugel verzichten oder aber die mangelhafte Lagerung und demgemäß nur geringe Öffnungshübe in Kauf nehmen müsse oder aber daß man die einwandfreie großhubige Führung der Verschlußkugel mit erheblichem Bearbeitungsaufwand und Verzichtcan be positively coupled without both losing their free rotation. This achieves the Invention in an amazingly simple way through the non-positive and positive interposition of a a non-return valve with only one movable closing body known spacer, which in the application according to the invention not only for a congruent, precisely fitting axial movement both locking balls ensures, but also the closing force of the spring-loaded repair locking ball used to allow both balls to easily approach their respective pan guide plates at the same time press so that the balls cannot fall out of the pan surfaces in any operating position of the valve, but without it being necessary to machine the surfaces of the balls and the sockets so precisely that. an appreciable adhesive force "is obtained, and without" that it is necessary to ensure the these. . Adhesion enabling molecular liquid film the valve exclusively as a faucet " to operate. So it was only known that either the advantageous all-round rotatability of the Do without the locking ball or else the inadequate storage and, accordingly, only small opening strokes You have to accept or that you have the perfect long-stroke guidance of the locking ball with considerable processing effort and waiver
