Abstract

The flap (1) locates in a cylindrical conduit incorporating a ring (13) on its inner wall (12), the flap bearing on this ring to effect closure and aligning in a plane parallel to the conduit axis when open. To effect sealed closure the flap bears a metal ring, of elliptical shape conforming to the conduit ring (13), locating in a groove formed by a stepping of the flap periphery and a screw (5) fixed retaining ring (4). This metal ring is of greater internal dia. (Dr) than the groove dia. (Ds) and is thus, able to deform elastically and radially during clamping of the retaining ring. The metal ring is composed of three annular discs with the outer discs projecting beyond the inner disc.

Description

Klappenventi 1 Die Erfindung betrifft ein Xlappenventil mit einem von der Gehäusewana des Ventils getragenen, in einem Winkel zur Normalebene des Gehäuses liegenden Dichtring und einer Klappe, die auf ihrem Umfang einen in Schließstellung der Klappe sich mit seinem Umfang gegen den Dichtring legendon Ring in einen Spalt zwischen dem Körper der Klappe und olnem darauf aug schraubten Befestigungsring trägt. Flap valve 1 The invention relates to a flap valve with a borne by the housing wana of the valve, at an angle to the normal plane of the Housing lying sealing ring and a flap that has a closed position on its circumference the flap itself with its circumference against the sealing ring legendon ring in a gap between the body of the valve and a fastening ring screwed on it wearing.

Klappenventile solcher Art sind bekannt durch die DT-PS 1 242 960.Flap valves of this type are known from DT-PS 1 242 960.

Es hat sich, insbesondere wenn der von der Klappe getragene Ring praktisch unelastisch ist, insb. aus Metall besteht, erwiesen, dass es schwierig ist sicherzustellen, dass der Ring auf seinem Umfang überall dicht an dem vom Gehäuse getragenen Dichtungsring anliegt.It has come in handy, especially when the ring carried by the flap is inelastic, especially made of metal, it has been proven that it is difficult to ensure that the ring is close to the sealing ring carried by the housing all over its circumference is present.

Aufgabe der Erfindung ist es, eine Konstruktion zu finden, die gewährleistet, dass im Schliesszustand des Klappenventils der von der Klappe getragene Ring auf seinem ganzen Umfange dicht an dem von der Gehäusewand getragenen Dichtring anliegt.The object of the invention is to find a construction that ensures that when the flap valve is closed, the ring carried by the flap opens its entire circumference lies tightly against the sealing ring carried by the housing wall.

Gemäss der Erfindung wird diese Aufgabe dadurch gelöst, dass der Innendurchmesser des den Ring aufnehmenden Spaltes kleiner ist als der Innendurchmesser des Ringes und dass die WAnde dieses Spaltes in radialer Richtung glatt sind.According to the invention, this object is achieved in that the inner diameter of the gap receiving the ring is smaller than the inner diameter of the ring and that the walls of this gap are smooth in the radial direction.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar einen Diagonalschnitt durch ein Klappenventil gemäss der Erfindung.The drawing shows an embodiment of the invention, namely a diagonal section through a flap valve according to the invention.

Die in der Zeichnung dargestellte Klappe 1 besitzt auf einer Seite zwei einander parallele Ansätze 2 mit einander fluchten?en Bohrungen 3 für eine Welle 9, die mit den Ansätzen 2 fest verbunden ist, durch die die zylindrische Wandung 7 des Klappenventils hinducchgeführt ist und dort mit einem Antrieb versehen ist, durch den die Welle 9 und somit auch die Klappe 1 um die Achse der Welle 9 gedreht werden kann. Der Klappenkörper 1 besitzt an seinem Rand eine kreisringförmige, stufenförmige Ausnehmung, deren Flächen in der Zeichnung mit 1a und 1b bezeichnet sind. Ein in die Ausnehmung passender Ring 4 ist mittels einer Anzahl von Schrauben 5 an den Klappenkörper 1 angeschraubt. In dem Spalt zwischen der Fläche 1a des Klappenkörpers 1 und der ihr gegenüberliegenden Fläche 4e des Ringes 4 ist ein metallischer Dichtungsring 6 eingesetzt. Der Dichtungsring 6 kann aus mehreren, beispielsweise acht, in achsialer Richtung nebeneinanderliegenden Ringen bestehen; in der Zeichnung sind zwei solcher Ringe dargestellt, Der Innendurchmesser Dr des Ringes 6 ist etwas grösser als der Innendurchmesser des durch die Wandungen 1a und 4a gebildeten Spaltes. Der Aussendurchmesser des Ringes 6 ist mindestene 1 mm, maximal etwa 10 mm grösser als der Anssendurchmesser des Klappenkrörpers 1. Die Flächen 1a und 4a und auch die Aussenflächen des Ringes 6 sind in radialer Richtung glatt. Sie liegen in Radialebenen den Klappenkörpers 1.The flap 1 shown in the drawing has on one side two parallel lugs 2 aligned with one another holes 3 for one Shaft 9, which is firmly connected to the lugs 2, through which the cylindrical wall 7 of the flap valve is guided through and is provided with a drive there, by which the shaft 9 and thus also the flap 1 is rotated about the axis of the shaft 9 can be. The flap body 1 has an annular, stepped shape on its edge Recess, the surfaces of which are denoted by 1a and 1b in the drawing. An in the recess matching ring 4 is by means of a number of screws 5 to the Flap body 1 screwed on. In the gap between the surface 1a of the valve body 1 and the opposite surface 4e of the ring 4 is a metallic sealing ring 6 used. The sealing ring 6 can consist of several, for example eight, axially Direction of adjacent rings exist; in the drawing there are two such Rings shown, the inner diameter Dr of the ring 6 is slightly larger than that Inner diameter of the gap formed by the walls 1a and 4a. The outside diameter of the ring 6 is at least 1 mm, at most about 10 mm larger than the anse diameter of the valve body 1. The surfaces 1a and 4a and also the outer surfaces of the ring 6 are smooth in the radial direction. They lie in radial planes of the valve body 1.

Bei der Montage der Klappe wird zunächst der Ring 6 auf die Fläche 1a des Klappenkörpers 1 gelegt. Dann wird der Ring 4 aufgesetzt und mittels der Schrauben 5 nur soweit angezogen, dass der Ring 6 sich in seiner Radialebene bewegen kann. Dann wird die Klappe in das Gehäuse 7 eingebaut. Dann wird die Welle 9 so weit gedreht, dass sich der Aussenumfang des Ringes 6 an dcn Dicn.tring 8 des Gehäuses 7 dicht anlegt. Das ist chne welteres möglich, weil der Ring 6 sich dabei in seiner Radialebene bewegen kann, so dass etwaige Unregelmässigkeiten in der Zentrierung des Dichtringes 8 ausgeglichen werden. Dann werden die Schrauben 5 festgezogen.When assembling the flap, the ring 6 is first placed on the surface 1a of the valve body 1 is placed. Then the ring 4 is put on and tightened by means of the screws 5 only to the extent that the ring 6 is in its radial plane can move. The flap is then installed in the housing 7. Then the wave 9 rotated so far that the outer circumference of the ring 6 on the Dicn.tring 8 of the Housing 7 rests tightly. This is more easily possible because the ring 6 is there can move in its radial plane, so that any irregularities in the centering of the sealing ring 8 are compensated. Then the screws 5 are tightened.
