Description

Die Erfindung betrifft einen auswechselbaren Ventilsitz für Wasserarmaturen, der leicht ein- und ausgebaut werden kann und eine lange Lebensdauer hat. Ventilsitze, die aus einer teilweise längs geschlitzten Büchse und einem gegen das Gehäuse abdichtenden Bund bestehen, der gleichzeitig als Sitzfläche dient, sind bekannt. Diese Ventilsitze bestehen aber aus Gummi, Fiber, Kupfer oder einem ähnlichen nachgiebigen Material, das selbstdichtend ist. Da bei diesem Material die Sitzfläche verhältnismäßig groß ist und deshalb nicht immer sicher abdichtet, wird nach der Erfindung vorgeschlagen, den Ventilsitz aus einem harten undelastischen Material, wie z. B. ihartverchromtem nichtrostendem Stahl, herzustellen und ihn durch eine besondere zwischen Bund und Gehäuse eingefügte Weichdichtung abzudichten, die durch den Schließdruck des Ventils angepreßt wird. Es ist zwar schon vorgeschlagen worden, auswechselbare Ventilsitze aus Stahl od. dgl. herzustellen, diese besitzen dann aber keinen Bund, mit dem sie sich auf der Gehäusebohrung abstützen und müssen geigen eine zylindrische Fläche abgedichtet werden. Sie haben den Nachteilkomplizierterer Gehäuseausbildunig und lassen sich nicht so leicht sickerdichtend einsetzen wie ein Ventilsitz nach der Erfindung.The invention relates to an exchangeable valve seat for water fittings, which can be easily installed and removed and has a long service life. Valve seats, which consists of a partially longitudinally slotted sleeve and a sleeve sealing against the housing The federal government, which also serves as a seat, are known. These valve seats but are made of rubber, fiber, copper or a similar flexible material, that is self-sealing. Because with this material the seat area is relatively large is and therefore not always securely seals, it is proposed according to the invention, the valve seat made of a hard and elastic material, such as. B. ihartchromtem stainless steel, and make it through a special between the collar and Housing inserted soft seal to seal by the closing pressure of the valve is pressed. Replaceable valve seats have already been proposed Made of steel or the like, but then they have no covenant with which they support themselves on the housing bore and must fiddle a cylindrical surface be sealed. They have the disadvantage of more complicated housing designs and cannot be used to seal seepage as easily as a valve seat after the Invention.

Der zum Aufsitzen des Ventilsitzes auf der Gehäusebohrung erforderliche Bund läßt sich durch 1JmM,rdeln der rohrartigen Büchse leicht herstellen.The one required for the valve seat to sit on the housing bore The collar can be easily produced by knurling the tubular sleeve.

In der Zeichnung zeigt Abb. i den Ventilsitz nach der Erfindung, eingebaut in eine Wasserarmatur, Abb. 2 den Ventilsitz einzeln in vergrößertem Maßstab. Die Büchse 3 ist geschlitzt, federt daher und kann des besseren Haltes wcgeit am Ende leicht aufgebogen sein. Das nicht geschlitzte Ende der Büchse ist zu einem die Sitzfläche bildenden Wulst i umgebördelt und hat einen Rand, mit dem der Ventilsitz auf der Weichdichtung 2 aufliegt.In the drawing, Fig. I shows the valve seat according to the invention, installed in a water fitting, Fig. 2, the valve seat individually on an enlarged scale. the Bushing 3 is slotted, therefore resilient and can wcgeit for better hold at the end be slightly bent up. The non-slotted end of the bushing becomes the seat forming bead i and has an edge with which the valve seat on the Soft seal 2 rests.
