Description

Abschlußkörper.Closing body.

Die einzelnen Punkte der Dichtungsringe von geradlinig bewegten Absperrschiebern legen beim öffnen und Schließen auf den Sitzringen-des Gehäuses Wege von sehr verschiedener Länge zurück; daraus erklärt sich auch ihr ungleicher Verschleiß. Man hat deshalb die Schieberplatten als reine Rundkörper ausgebildet und sie in einem Bügel so gelagert, daß sie sich in ihm frei verdrehen können;The individual points of the sealing rings of linearly moving gate valves place on the seat rings when opening and closing Housing paths of very different length back; this also explains their uneven wear. That's why you have the slide plates are designed as pure round bodies and are stored in a bracket in such a way that that they can twist freely in him;

ίο ferner hat man die Drehung der Teller durch von außen verstellbare Anschläge erzwungen, derartige Hilfsmittel verteuern die Herstellung und erschweren den Betrieb.
Vorliegende Erfindung zeigt, wie ohne Zufügung eines einzigen Teiles durch die Führungsflächen selbst eine Drehung der Platten erzielt und die Abnutzung vergleichmäßigt werden kann.
Beim öffnen· des geschlossenen Schiebers
Furthermore, the rotation of the plate has been forced by means of externally adjustable stops, such aids make production more expensive and make operation more difficult.
The present invention shows how a rotation of the plates can be achieved and the wear can be evened out without the addition of a single part by the guide surfaces themselves.
When opening · the closed slide

ao (Abb. i) tritt der vom Bügel b umfaßte Körper α auf Führungsflächen c über, die ungefährao (Fig. i), the body α encompassed by the bracket b passes over onto guide surfaces c , which are approximately

in einer Ebene mit den Sitzringen liegen, deren zur Längs-Mittelebene des Gehäuses ungleiche Anordnung (Abb. 2) aber auf den vom Dampf nach links oder rechts gedrückten 25 Teller« durch einseitige Reibung ein Drehmoment ausübt. Es wäre ein höchst unwahrscheinlicher Zufall, wenn der Schieber α nach seiner Betätigung in dieselbe Drehlage zurückkehrte, die er vorher eingenommen hatte.lie in a plane with the seat rings, the arrangement of which is unequal to the longitudinal center plane of the housing (Fig. 2), but exerts a torque on the plates pushed to the left or right by the steam due to one-sided friction. It would be a highly unlikely coincidence if the slide α returned to the same rotational position after its actuation as it had previously assumed.

Patent-Anspruch:Patent claim: Absperrschieber mit geradlinig bewegtem, in einem Bügel drehbar gelagertem Abschlußkörper, der beim öffnen auf Führungsflächen übertritt, dadurch gekennzeichnet, daß die Führungsflächen unsymmetrisch geformt oder angeordnet sind, so daß der Abschließkörper infolge einseitiger Reibung an den Führungsflächen gedreht wird.Gate valve with linearly moved, rotatably mounted in a bracket Closing body which crosses over to guide surfaces when opening, characterized in that that the guide surfaces are shaped or arranged asymmetrically, so that the closure body as a result of one-sided Friction on the guide surfaces is rotated.
