Description
Die Erfindung betrifft eine Klappe, insbesondere zum Einbauen in Rohrleitungen, mit einem Klappengehäuse, an dessen zwei axialen Enden Rohrleitungen montierbar sind, mit einer in dem Klappengehäuse schwenkbar gelagerten Klappenscheibe, die in Schließrichtung radial gegen einen Sitzring im Klappengehäuse abdichtet, der aus einem Dichtring und einem den Dichtring radial umfassenden, radial abgestützten Tragring besteht, wobei der Dichtring mit seinen axialen Stirnflächen jeweils axial über die Enden des Klappengehäuses übersteht und den Tragring U-förmig umschließt.The invention relates to a flap, in particular for installation in pipelines, with a flap housing, at the two axial ends of which pipelines can be mounted, with a flap disc pivotably mounted in the flap housing, which seals radially in the closing direction against a seat ring in the flap housing, which consists of a sealing ring and a radially supported support ring which radially surrounds the sealing ring, wherein the sealing ring with its axial end faces projects axially beyond the ends of the flap housing and encloses the support ring in a U-shape.
Im Stand der Technik sind unterschiedliche Möglichkeiten zur Verbindung einer beispielsweise wasserführenden Armatur mit einem Rohr oder Rohrstutzen bekannt. Eine solche Verbindung kann dadurch erfolgen, daß in das einteilige Klappengehäuse je nach gewünschtem Rohrverbindungssystem unterschiedliche Rohranschlußkonturen für Muffen, Spitzenden, Sonderflansche, Steckverbindungen, Bajonettverbindungen, Anschweißflansch etc. eingegossen werden. Die Klappengehäuse unfassen dabei einstückig ausgebildete Flansche, die Gewindebohrungen zur Befestigung von Gegenflanschen an der Rohrleitung aufnehmen.In the state of the art, different possibilities for connecting a water-carrying fitting, for example, to a pipe or pipe socket are known. Such a connection can be made by casting different pipe connection contours for sockets, spigots, special flanges, plug connections, bayonet connections, weld-on flanges, etc. into the one-piece valve housing, depending on the desired pipe connection system. The valve housings include one-piece flanges that accommodate threaded holes for attaching counter flanges to the pipeline.
Nachteilig sind die hiermit verbundenen hohen Kosten für Gussteile, die zum einen besondere teure Formen für jede Klappengröße benötigen, zum anderen nach dem Gießen noch aufwendige mechanische Bearbeitungsvorgänge, insbesondere an den Flanschen erfordern. Ein weiterer Nachteil ist, daß für jede Verbindungsart und Baulänge separate Gehäuse gegossen werden müssen. Dies bedingt kleine Stückzahlen, häufiges Nachrüsten und hohe Lagerkosten.The disadvantage is the high cost of cast parts, which require special, expensive molds for each valve size and, after casting, require complex mechanical processing, particularly on the flanges. Another disadvantage is that separate housings have to be cast for each connection type and length. This means small quantities, frequent retrofitting and high storage costs.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Klappe gattungsgemäßer Art zu schaffen, mittels derer alle auf dem Markt befindlichen Rohrverbindungssysteme mit einem kostenreduzierten Standard-Klappengehäuse abgedeckt werden können.Based on this prior art, the invention is based on the object of creating a flap of this generic type by means of which all pipe connection systems available on the market can be covered with a cost-reduced standard flap housing.
Zur Lösung dieser Aufgabe wird vorgeschlagen, an den Außenseiten des Klappengehäuses mindestens ein axiales Innengewinde mit einem Durchmesser, der größer als der Durchmesser des freien Durchgangs ist, anzuordnen, im Anschluss an das Innengewinde eine senkrechte Anlagefläche am Klappengehäuse auszubilden und in das Innengewinde ein Adapterstück mit Außengewinde einzuschrauben, dessen Stirnseite an der Anlagefläche des Gehäuses und den axial überstehenden axialen Stirnflächen des Dichtrings anliegt, so daß das Adapterstück mit dem Klappengehäuse und der Rohrleitung fluiddicht verbunden werden kann.To solve this problem, it is proposed to arrange at least one axial internal thread with a diameter that is larger than the diameter of the free passage on the outer sides of the valve housing, to form a vertical contact surface on the valve housing following the internal thread and to screw an adapter piece with an external thread into the internal thread, the front side of which rests on the contact surface of the housing and the axially projecting axial end faces of the sealing ring, so that the adapter piece can be connected to the valve housing and the pipeline in a fluid-tight manner.
Der verblüffende Vorteil der Lehre des Anspruchs 1 liegt darin, daß das Klappengehäuse unabhängig von dem gewünschten Rohranschlußssytem fabrikmäßig hergestellt und vorgehalten werden kann. Aufwendige Gießformen und Modelle entfallen. Die Adapterstücke können ebenfalls fabrikmäßig produziert und vorgehalten werden. Insbesondere reduzieren sich die Lagerkosten, da die vorgehaltenen Adapterstücke einen geringeren Wert als das komplette herkömmliche Klappengehäuse haben. Die Adapterstücke werden vor Auslieferung oder erst am Einbauort mit dem Klappengehäuse lediglich fluiddicht verschraubt.The amazing advantage of the teaching of claim 1 is that the flap housing can be manufactured and kept in stock in the factory, regardless of the desired pipe connection system. Complex molds and models are not required. The adapter pieces can also be manufactured and kept in stock in the factory. In particular, storage costs are reduced, since the adapter pieces kept in stock have a lower value than the complete conventional flap housing. The adapter pieces are simply screwed to the flap housing in a fluid-tight manner before delivery or at the installation site.
Bevorzugt ist dabei vorgesehen, daß an dem Adapterstück ein zylindrischer Rohrverbindungssteg zur Herstellung einer Verbindung zwischen Adapterstück und Rohrleitung angeordnet ist. An dem Rohrverbindungssteg können zu allen marktüblichen Rohranschlußsystemen komplementäre ein- oder mehrstückige Befestigungsvorsprünge angeordnet werden.Preferably, a cylindrical pipe connection web is arranged on the adapter piece to create a connection between the adapter piece and the pipeline. Complementary single or multi-piece fastening projections can be arranged on the pipe connection web for all commercially available pipe connection systems.
Das Adapterstück ist vorzugsweise einteilig ausgebildet.The adapter piece is preferably made in one piece.
Nach einer weiteren Ausführungsform ist die Anlagefläche des Gehäuses senkrecht zur Rohrleitung ausgebildet. Dadurch kann ein optimaler Anpressdruck desAccording to a further embodiment, the contact surface of the housing is designed perpendicular to the pipe. This allows an optimal contact pressure of the
Adapterstücks auf das Gehäuse, insbesondere auf die Stirnfläche des Dichtrings erzielt werden.adapter piece onto the housing, particularly onto the front face of the sealing ring.
Nach einer bevorzugten Ausführungsform ist der Innendurchmesser des Rohrverbindungssteges größer als der Außendurchmesser der Rohrleitung. So können die handelsüblichen Steckmuffenverbindungen realisiert werden.According to a preferred embodiment, the inner diameter of the pipe connection web is larger than the outer diameter of the pipeline. In this way, standard push-in socket connections can be realized.
Ferner wird vorgeschlagen, den Außendurchmesser des Rohrverbindungssteges kleiner als den Innendurchmesser der Anschlußrohrleitung auszubilden, sofern die Steckmuffe an der Anschlußrohrleitung angeordnet ist.It is further proposed to make the outer diameter of the pipe connection web smaller than the inner diameter of the connecting pipe, provided that the plug-in sleeve is arranged on the connecting pipe.
Nach einer weiteren bevorzugten Ausführungsform ist der Außendurchmesser des Rohrverbindungssteges gleich groß wie der Außendurchmesser der Rohrleitung. Damit lassen sich die aufsetzbaren Verbindungsmuffen-Systeme (Kupplungen) realisieren.According to a further preferred embodiment, the outer diameter of the pipe connection web is the same size as the outer diameter of the pipeline. This makes it possible to implement attachable connection sleeve systems (couplings).
Das Adapterstück wird vorzugsweise aus metallischen und/oder nicht-metallischen Werkstoffen hergestellt.The adapter piece is preferably made of metallic and/or non-metallic materials.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnungen dargestellt und im Folgenden näher beschrieben. Es zeigt Fig. 1 eine erfindungsgemäße Klappe mit zwei Adapterstücken im Längsschnitt.An embodiment of the invention is shown in the drawings and described in more detail below.
