Description
Die Erfindung betrifft einen Keilschieber mit zwei in ein Querhaupt mit rädialem und axialem Spiel eingesetzten Verschlußplatten, welche von dem nach .dem Aufsetzen .der Verschlußplatten noch weiter bewegten Querhaupt mittels eines zylindrischen Bolzens, -der quer zur Durchflußrichtung am -Querhaupt befestigt ist, gegen die Sitzringe gepreßt werden.The invention relates to a wedge slide with two in one crosshead with radial and axial play used closure plates, which of the after .the placing .the closure plates still further moved crosshead by means of a cylindrical bolt, which is attached to the transverse head at right angles to the direction of flow, pressed against the seat rings.
Bei dieser Art von Schiebern preßt der Bolzen des Keilwinkels gegen die Verschlußplatten. Ist er -in einer Rohrleitung für ein strömendes heißes Mittel, etwa Wasserdampf, eingebaut, so wird das Gehäuse nach dem Schließen erkalten und die Zusammenziehung des. Gehäuses den Anpreßdruck erhöhen, so daß das Öffnen des Schiebers große Kräfte erfordert. Zur Vermeidung dieser Selbstsperrung sind gelenkige Hebelübertragungen od. dgl. benutzt worden, welche jedoch die beim Keilschieber angestrebte und besonders geschätzte geringe Breite des Verschlußkörpers in Strömungsrichtung wieder vergrößern.In this type of slider, the pin of the wedge bracket presses against it the locking plates. Is he -in a pipeline for a flowing hot medium, such as water vapor, built in, the housing will cool down after closing and the contraction of the. Housing increase the contact pressure, so that the opening of the Slide requires great forces. To avoid this self-locking are articulated Lever transmissions or the like. Has been used, but which is the case with the wedge slide desired and particularly valued small width of the closure body in the direction of flow enlarge again.
Gemäß der Erfindung wird zwischen jede Verschlußplatte und den Bolzen ein Zu ihm konzentrisches Ringzylindersegment, welches sich gegen die ebenen Rückseiten der Schieberplatten anlegt, als Glied der Kraftübertragung eingeschaltet. Es wandelt die- gleitende Reibung an der Verschlußplatte in rollende Reibung um und gewährleistet dadurch ein kraftsparendes Öffnen und Schließen des Schiebers. Im Vergleich zu den Anpreßvorrichtungen mit Hebelübertragung, die über Rollen und an den Plattenrückseiten angebrachte .schalenförmige Aussparungen angreift, beanspruchen die Ringzylindersegmente wenig Platz.According to the invention, between each locking plate and the bolt a ring cylinder segment concentric to it, which is against the flat rear sides the slide plate applies, switched on as a link in the power transmission. It changes the sliding friction on the closure plate converts into rolling friction and ensures This enables effortless opening and closing of the slide. Compared to the Pressure devices with lever transmission, which are on rollers and on the back of the panels Attached .shell-shaped recesses, stress the ring cylinder segments little space.
Das Sehiebergehäuse i ist mit den aufgeschweißten Dichtringen 2 und 3 versehen. Dazwischen bewegt sich in lotrechter Richtung das mit der Schieberspindel 4 fest verbundene Querhaupt 5; in welches die Dichtplatten 6 und 7 lose eingesetzt sind. Das Querhaupt 5 hat eine prismatische öffnung 8, durch welche der Bolzen 9 hindurchgeht, der in den Seitenwänden des Querhauptes befestigt ist. Er . ist von zwei zylindrischen Sektoren io und i i umgeben, welche unten nur wenig voneinander abstehen und ihn nach oben um etwa 45° über die Waagerechte umgreifen. Ansätze 1a am Querhaupt 5 begrenzen die Drehbewegung dieser Sektoren io und ir nach oben.The filter housing i is with the welded-on sealing rings 2 and 3 provided. In between, the one with the slide spindle moves in a vertical direction 4 permanently connected crosshead 5; in which the sealing plates 6 and 7 are loosely inserted are. The crosshead 5 has a prismatic opening 8 through which the bolt 9 which is fixed in the side walls of the crosshead. He is of two cylindrical sectors io and i i surround, which at the bottom only slightly from each other stand out and grip it upwards by about 45 ° above the horizontal. Approaches 1a on the crosshead 5 limit the rotational movement of these sectors io and ir upwards.
Beim Schließen ebenso beim Öffnen des Schiebers wälzen sich diese Sektoren io und ii auf den Schieberplatten6 und 7 ab, während sie auf dem Bolzen 9 gleiten. Dieses Gleiten auf dem Bolzen hört jedoch beim Öffnen schon auf, sobald die elastische Durchbiegung der Dichtplatten 6 und 7 aufgehoben ist. Zweckmäßig werden die Sektoren io und, ii auf ihren Außenflächen leicht balli:g gehalten, damit sie zentrisch angreifen.When closing, as well as when opening the slide, these roll over Sectors io and ii on the slide plates 6 and 7 while they are on the bolt 9 slide. However, this sliding on the bolt stops as soon as it is opened the elastic deflection of the sealing plates 6 and 7 is canceled. Appropriate the sectors io and ii are kept slightly balli: g on their outer surfaces, so attack them centrically.
