Description

Absperrschieber Zusatz zur Anmeldung: D 42399 X11/47 g -Auslegeschrift 1211047 Die Erfindung bezieht sich auf einen Absperrschieber ohne Gehäusesack mit ein- oder beidseitig abdichtendem, keilförmigem Verschlußstück, das im unteren Teil radial und im oberen Teil axial abdichtet und von einer nichtsteigenden Spindel bewegt wird, wobei als Dichtelement ein O-Ring verwendet wird, der in eine im oberen Teil des Verschlußstückes stirnseitig, im unteren Teil am Umfang verlaufenden Nut eingelegt ist, nach Patentanmeldung D 42399 XII/47 g (deutsche Auslegeschrift 1211047). Bei derartigen Absperrschiebern hat sich als nachteilig herausgestellt, daß die Reibung zwischen der Anlagefläche im Gehäuse und dem darauf in die Verschlußstellung gleitenden O-Ring des Verschlußstückes größer ist als diejenige zwischen dem O-Ring und seiner Haftfläche im Verschlußstück. Dadurch wird er O-Ring beim Öffnen und Schließen teils gedehnt und teils gestaucht. Diese ständige wechselweise Beanspruchung bei häufiger Betätigung kann dazu führen, daß der O-Ring schließlich reißt, so daß die Abdichtung gefährdet ist.Gate valve Addendum to registration: D 42399 X11 / 47 g - Auslegeschrift 1211047 The invention relates to a gate valve without a housing bag one or both sides sealing, wedge-shaped closure piece, which is in the lower part Seals radially and axially in the upper part and from a non-rising spindle is moved, with an O-ring being used as a sealing element, which is inserted into an in the upper Part of the locking piece at the front, in the lower part of the circumference running groove is inserted, according to patent application D 42399 XII / 47 g (German Auslegeschrift 1211047). In such gate valves has been found to be disadvantageous that the Friction between the contact surface in the housing and the one on it in the closed position sliding O-ring of the closure piece is larger than that between the O-ring and its adhesive surface in the closure piece. This will make it an O-ring when opening and Closing partly stretched and partly compressed. This constant alternating stress frequent operation can cause the O-ring to eventually tear, so that the seal is at risk.

Um diesen Übelstand zu beheben, wird gemäß der Erfindung vorgeschlagen, .die Anlagefläche für den O-Ring im oberen Teil des Schiebergehäuses mit einer nichtrostenden glatten Schicht, z. B. aus Emaille, Kunststoff oder einem Metallüberzug, zu versehen.In order to remedy this drawback, it is proposed according to the invention, .the contact surface for the O-ring in the upper part of the valve body with a stainless steel smooth layer, e.g. B. made of enamel, plastic or a metal coating.

In weiterer Ausgestaltung des Erfindungsgedankens kann zusätzlich die Oberfläche der den O-Ring aufnehmenden Ringnut im Verschlußstück rauh gehalten werden, indem die Gußfläche in der Ringnut unbearbeitet gelassen wird. Es kann aber auch .die Querschnittsabmessung der Ringnut derart gewählt werden, daß der O-Ring in die Nut eingeklemmt wird, z. B. durch Hinterschneiden der Nut. Durch die Anwendung einer oder mehrerer der geschilderten Maßnahmen wird jede unzulässige Beanspruchung des O-Ringes bei der Betätigung des Verschlußstückes vermieden und dadurch ein Unbrauchbarwerden der Abdichtung ausgeschaltet.In a further embodiment of the inventive concept, in addition the surface of the annular groove receiving the O-ring in the closure piece is kept rough by leaving the cast surface in the annular groove unmachined. But it can also .the cross-sectional dimension of the annular groove can be selected such that the O-ring is clamped in the groove, e.g. B. by undercutting the groove. Through the application one or more of the measures outlined will prevent any impermissible stress of the O-ring when actuating the locking piece and thereby becoming unusable the seal turned off.
