Abstract
Description
Die vorliegende Erfindung betrifft ein Steuerrohr für ein Coaxialventil mit einem am Steuerrohr angeordnetem Ventilschließkörper.The present invention relates to a head tube for a coaxial valve with a valve closing body arranged on the head tube.
Der Ventilschließkörper eines herkömmlichen Coaxialventils wird getrennt von dem Steuerrohr gefertigt und meist mittels Verschrauben, Kleben, Schweißen oder Löten am Steuerrohr befestigt. Das Steuerrohr wird dabei meist aus einem Rohr gefertigt, wobei der Ventilschließkörper durch eine Dreh- und Fräsbearbeitung hergestellt wird. Nachteilig bei dieser Bauweise ist, daß mehrere Fertigungsschritte an mehreren Werkstücken und Werkzeugen notwendig sind, wobei diese anschließend montiert werden müssen.The valve closing body of a conventional one Coaxial valves are usually made separately from the head tube attached to the head tube by screwing, gluing, welding or soldering. The Head tube is usually made from a tube, the Valve closing body through a turning and milling process will be produced. The disadvantage of this design is that several Manufacturing steps on several workpieces and tools necessary are, afterwards must be installed.
Aufgabe der vorliegenden Erfindung ist es, eine Steuerrohr für ein Coaxialventil bereitzustellen, welches aus wenigen Teilen besteht und einfach und kostengünstig in der Herstellung ist.Object of the present invention is a head tube for to provide a coaxial valve which consists of a few parts and simple and inexpensive is in the making.
Diese Aufgabe wird erfindungsgemäß mit einem Steuerrohr gemäß den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Steuerrohrs nach Anspruch 1 ergeben sich durch die Merkmale der Unteransprüche.This object is achieved with a Head tube according to the characteristics of claim 1 solved. Further advantageous configurations of the head tube according to the invention according to claim 1 result from the features of the subclaims.
Das erfindungsgemäße Steuerrohr zeichnet sich vorteilhaft dadurch aus, daß das Steuerrohr zusammen mit dem Ventilschließkörper einstückig ausgebildet ist. Das erfindungsgemäße Steuerohr kann dabei vorteilhaft aus einem Vollprofil herausgedreht und/oder gefräst werden. Durch die Einstückigkeit von Steuerrohr und Ventilschließkörper entfallen vorteilhaft die bei herkömmlichen Steuerrohren erforderlichen Montageschritte zur Befestigung des Ventilschließkörpers am Steuerrohr selbst. Zudem werden Montagefehler ausgeschlossen und die Standzeit des Steuerrohrs vorteilhaft erhöht. Auch entfallen zusätzliche Kosten durch die geringere Anzahl an Fertigungsschritten wie z.B. Ablängen, Einspannen , Umspannen, Positionieren, die für jedes einzelne Bauteil notwendig wären. Eine weitere Kostenreduktion liegen in der Zeiteinsparung durch die kürzeren Prozeßzeiten, da die Nebenzeiten, die durch den Transport und die Zwischenlagerung aufgrund der Auslastung der einzelnen Maschinen entstehen können, reduziert werden. Auch die Transportkosten und die Zwischenlagerungskosten können so reduziert werden.The head tube according to the invention stands out advantageous in that the Control tube is integrally formed together with the valve closing body. The control ear according to the invention can advantageously be turned out of a full profile and / or milled become. Due to the one piece of Head tube and valve closing body are eliminated advantageous that with conventional Steering tubes required assembly steps to attach the Valve closing body on Head tube itself. In addition, assembly errors are excluded and the service life of the head tube advantageously increased. There are also no additional ones Costs due to the lower number of manufacturing steps such as Cut, Clamping, reclamping, positioning, which is necessary for each individual component would. Another cost reduction lies in the time saved the shorter process times, because of the non-productive times caused by transport and intermediate storage reduced due to the utilization of the individual machines become. Also the transport costs and the intermediate storage costs can so be reduced.
Der Ventilschließkörper ist vorteilhaft ein konusförmiges Teil, welches über mindestens einen Verbindungssteg am Rohr des Steuerrohrs angeformt ist. Der größte Außendurchmesser des Ventilschließkörpers ist dabei in Relation zum Innendurchmesser des Rohres des Steuerrohrs so zu bemessen, daß fensterartige Durchtrittsöffnungen zwischen dem Ventilschließkörper und dem Rohr bzw. dessen Stirnseite gebildet sind, deren Öffnungsquerschnitt hinreichend groß für den geforderten Mengenstrom des Mediums durch das Coaxialventil ist. Es hat sich gezeigt, die Anordnung dreier Verbindungststege im Abstand von jeweils 120° zueinander eine hinreichend feste Verbindung zwischen Ventilschließkörper und Rohr ergibt, die die vom Ventilsitz auf den Ventilschließkörper angreifenden Reaktionskräfte sicher auf das Rohr übertragen. Gleichzeitig wird beim Vorsehen von drei Verbindungsstegen ein hinreichend großer Öffnungsquerschnitt der fensterartigen Öffnungen erzielt.The valve closing body is advantageously a conical part, which about at least one connecting web formed on the tube of the head tube is. The largest outside diameter of the valve closing body in relation to the inner diameter of the tube of the head tube to be dimensioned so that window-like Through openings between the valve closing body and the tube or its end face are formed, the opening cross section of which is sufficient great for the required Volume flow of the medium through the coaxial valve. It has shown, the arrangement of three connecting webs at a distance of 120 ° from each other a sufficiently firm connection between the valve closing body and Pipe results that the attacking from the valve seat on the valve closing body reaction forces transferred safely to the pipe. At the same time, if three connecting bridges are provided, one is sufficient large opening cross-section the window-like openings achieved.
Zur Reduzierung der Strömungsgeräusche und zur Minderung des Strömungswiderstands des Coaxialventils, ist der Ventilschließkörper strömungsgünstig auszuformen. Hierzu kann der Ventilschließkörper vorzugsweise zwei konusförmige Bereiche aufweisen, wobei der erste Bereich mit dem Ventilsitz zusammenwirkt und der zweite Bereich im Steuerrohr befindlich ist. Die beiden konusförmigen Bereiche sind dabei über einen Verbindungsbereich miteinander verbunden, wobei die Durchmesser der beiden Bereiche zu ihren freien Enden hin kleiner werden. Aus strömungstechnischen Gründen kann es vorteilhaft sein, die konusförmigen Bereiche nicht spitz, sondern stumpf auszubilden. Die jeweilige Ausgestaltung und die Abmessungen des Steuerrohrs und seiner einzelnen Komponenten sollte in jedem Fall den jeweiligen Bedingungen und Anforderungen angepaßt sein.To reduce the flow noise and to reduce the flow resistance of the coaxial valve, the valve closing body is to be shaped in a streamlined manner. This can the valve closing body preferably two conical Have areas, the first area cooperating with the valve seat and the second area is in the head tube. The two conical Areas are over a connection area connected to each other, the diameter of the two areas become smaller towards their free ends. Out fluidic establish it may be advantageous not to make the conical areas pointed, but to train dull. The respective design and the Dimensions of the head tube and its individual components should in any case be adapted to the respective conditions and requirements.
Nachfolgend wird eine vorteilhafte Ausführungsform des erfindungsgemäßen Steuerrohrs für ein Coaxialventil anhand von Zeichnungen näher erläutert.Below is an advantageous one embodiment of the head tube according to the invention for a Coaxial valve explained in more detail with reference to drawings.
