Description

Die Erfindung bezieht sich auf ein Absperrventil aus Kunststoff, bei welchem die den Ventilkegel tragende Spindel im Gehäusestutzen gegen Axialverschiebung gesichert ist und der Gehäusestutzen eine ein Hindurchdringen von Flüssigkeit verhindernde Dichtung enthält.The invention relates to a shut-off valve made of plastic which the spindle carrying the valve cone in the housing connector against axial displacement is secured and the housing connector is a penetration of liquid preventing Includes seal.

Nach der Erfindung weist die Ventilspindel einen Bund auf, der zwischen zwei in die Bohrung des Gehäusestutzens eingesetzten Ringscheiben liegt und von an der Böhrungswandung dicht anliegenden Gummiringen belastet ist. Außerdem ist die Spindel von einer eine Anlage der Gummiringe an ihr hindernden Büchse umgeben sowie in die Bohrung ein auf die Ringe wirkendes Druckstück mit begrenzter Eingriffstiefe eingesetzt und mit einer auf den Stutzen aufgeschraubten Überwurfmutter gegen die Ringe angezogen. Hierdurch ist ein Absperrventil geschaffen, welches, vollständig aus Kunststoff bestehend, leichtgängig ist, dennoch aber eine vollkommen dichte Spindeleinführung aufweist sowie sich leicht zusammenbauen läßt. Einen übermäßigen Dichtungsdruck und einen durch diesen verursachten zu großen Widerstand gegen Drehen der Spindel verhindert die begrenzte Eingriffstiefe des Druckstücks, während die die Spindel umgebende Büchse letztere vor einer lieminenden Reibung an den Gummiringen bewahrt und gleichzeitig den Hub der Ventilspindel nach außen begrenzt.According to the invention, the valve spindle has a collar that is between two annular disks inserted into the bore of the housing socket and from on the wall of the bore tightly fitting rubber rings is loaded. Also is the spindle is surrounded by a bushing that prevents the rubber rings from resting against it as well as in the bore a pressure piece acting on the rings with a limited depth of engagement inserted and with a union nut screwed onto the nozzle against the Rings tightened. This creates a shut-off valve which, completely Made of plastic, it runs smoothly, but is still completely tight Has spindle lead-in and is easy to assemble. An excessive one Sealing pressure and excessive resistance to rotation caused by it the spindle prevents the limited depth of engagement of the pressure piece, while the the sleeve surrounding the spindle, the latter from rubbing against the rubber rings and at the same time limits the stroke of the valve spindle to the outside.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung.The drawing illustrates an embodiment of the invention.

Das Ventilgehäuse i und der Gehäusestutzen 2 sind einstückig und bestehen aus Kunststoff. Desgleichen bestehen sämtliche weiteren Teile mit Ausnahme der Ringe 12 und der Ringscheibe i i aus Kunststoff. Der Ventilkegel 3 sitzt mit Schraubengewinde auf der Spindel 4 und ist in der Büchse 5 durch Drehen der Spindel axial verschiebbar. Die Büchse 5 ist in das Gehäuse eingesetzt und ruht auf der Schulter 6 auf. Die Leiste 7 am Ventilkegel, welche in eine Nut der Büchse 5 eingreift, sichert den Ventilkegel gegen Drehen. Durch den Eingriff des Vorsprunges 5 im Gehäusestutzen in eine entsprechende Nut der Büchse 5 ist letztere gegen Drehen gesichert.The valve housing i and the housing connector 2 are integral and consist made of plastic. There are also all other parts with the exception of the rings 12 and the washer i i made of plastic. The valve cone 3 is screw-threaded on the spindle 4 and is axially displaceable in the sleeve 5 by rotating the spindle. The sleeve 5 is inserted into the housing and rests on the shoulder 6. the Bar 7 on the valve cone, which engages in a groove in the sleeve 5, secures the Valve cone against turning. Through the engagement of the projection 5 in the housing connector in a corresponding groove in the sleeve 5, the latter is secured against turning.

Die Ventilspindel weist einen Bund 9 auf. Dieser Bund liegt zwischen den beiden Ringscheiben io und i i. Oberhalb der Ringscheibe i i sind die Gummiringe 12 vorgesehen, deren Anlage an die Spindel durch die Büchse 13 verhindert ist. Durch die Länge der Büchse 13 wird der Hub der Spindel 4 begrenzt und eine übermäßige Pressung der Gummiringe 12 durch den Druck im Ventil verhütet.The valve spindle has a collar 9. This covenant lies between the two ring disks io and i i. Above the washer i i are the rubber rings 12 is provided, the contact of which on the spindle is prevented by the sleeve 13. By the length of the sleeve 13, the stroke of the spindle 4 is limited and excessive Pressing the rubber rings 12 prevented by the pressure in the valve.
