Description
Die Erfindung bezieht sich auf einen Absperrschieber mit parallelen Dichtungsteilem, der besonders gut für hohe Drücke und hohe Temperaturen geeignet ist.The invention relates to a gate valve with parallel sealing parts, which is particularly suitable for high pressures and high temperatures.
Bei bekannten Schiebern sind die Dichtungsringe in den Abdichtungstellern durch
Einstemmen oder Verschweißen fest mit dem Gußkörper verbunden und haben wegen der
Verschiedenheit der Materialien die. Neigung, sich bei hohen Temperaturen zu werfen und
zu lockern, wodurch die Dichtigkeit des Schiebers beeinträchtigt wird. Die Konstruktionen
mit starren Innenteilen verlangen als Druckkeile sehr große Steigung, um auf jedem Fall die Selbsthemmung oder ein
Festsetzen zu vermeiden. Als Nachteil muß hier in Kauf genommen werden, daß die Andrückverhältnisse ungünstiger werden und
beim Erkalten sehr große Drücke auf die Innenteile kommen. Auch Konstruktionen, in
denen unter die Ringe elastische Dichtungen untergelegt sind, sind bekannt; sie haben
den Nachteil, daß bei hohen Drücken <ein hoher spezifischer Druck das elastische Material
ungünstig beeinflußt. Außerdem beanspruchen diese Konstruktionen 'eine besondere
Festhaltevorrichtung, welche eine unerwünschte Verteuerung mit sich bringt.
Alle diese Nachteile werden erfmdungsgemäß dadurch vermieden, daß die Dichtungsplatten
mit einem dünnwandigen Rande versehen sind, unter dem zwecks günstiger
Druckverteilung und wegen der erwünschten Elastizität eine scheibenförmige, elastische
Unterlage angeordnet ist. Die an Stelle der Ringe getretenen Platten können sich frei
ausdehnen und sich wegen des dünnen Plattenrandes auch Verziehungen des Gehäuses
anpassen. Die 'elastische Unterlage trägt den Verspannungen und Ausdehnungen der Gehäuse und Innenteile der Schieber
Rechnung, indem sie ausgleichend wirkt und die Starrheit der angepreßten Innenteile aufhebt.
In known slides, the sealing rings in the sealing plates are firmly connected to the cast body by caulking or welding and, because of the difference in materials, have the. A tendency to throw and loosen at high temperatures, thereby compromising the tightness of the slide. The constructions with rigid inner parts require a very large gradient as pressure wedges in order to avoid self-locking or seizing in any case. The disadvantage that must be taken into account here is that the pressure conditions become less favorable and very high pressures are exerted on the inner parts when they cool down. Constructions in which elastic seals are placed under the rings are also known; they have the disadvantage that at high pressures <a high specific pressure has an unfavorable effect on the elastic material. In addition, these constructions claim 'a special retaining device, which brings with it an undesirable increase in cost.
All these disadvantages are avoided according to the invention in that the sealing plates are provided with a thin-walled edge, under which a disk-shaped, elastic base is arranged for the purpose of favorable pressure distribution and because of the desired elasticity. The plates that have taken the place of the rings can expand freely and, due to the thin plate edge, also adapt to distortions of the housing. The 'elastic pad takes the tension and expansion of the housing and internal parts of the slide into account by having a balancing effect and eliminating the rigidity of the pressed-on internal parts.
Φ5 Ein Beispiel für die Anwendung der Erfindung 'und zwei Beispiele für die neben anderen möglichen Ausführungsformen der Platten zeigen die Zeichnungen.Φ5 An example of the application of the invention 'and two examples of the other possible embodiments of the Plates show the drawings.
Abb. ι zeigt einen Schnitt durch den geschlossenen Schieber.Fig. Ι shows a section through the closed Slider.
Abb. 2 zeigt 'eine zweite Ausführungsform der Abdichtungsteller mit einer elastischen Dichtung.Fig. 2 shows a second embodiment of the sealing plate with an elastic one Poetry.
18 bzw. 19 sind die an Stelle der· Ringe getretenen Platten, 20 bzw. 21 stellt die elastische Masse dar, die zwischen dem Druckkörper und der Dichtungsplatte 'eingelagert ist. 22 ist ein gehärtetes Druckstück, das den Preßdruck vom Keil 3 emp-. fängt. Die Auf- und Abwärtsbewegung der Platten erfolgt durch die Spindel 2, die von einem nicht steigenden Handrad 1 bedient wird.18 and 19 are those in place of the rings stepped plates, 20 and 21 represents the elastic mass between the Pressure hull and the sealing plate 'is embedded. 22 is a hardened pressure piece, that the pressing pressure from the wedge 3. catches. The up and down movement of the Plates are made by the spindle 2, which is operated by a handwheel 1 that does not rise will.
ÖffnungsvorgangOpening process
,Durch Linksdrehung des Handrades 1 macht die Spindel 2 eine steigende Bewegung und hebt den Anpreßdruck auf die Abdichtungsteller auf. Nicht gezeichnete Blokkierungshebel und Führungsleisten kuppeln die Abdichtungsteller mit der Spindel so, daß eine Verschiebung der Teller zur Spindel nicht eintreten kann. Die Teller werden aus der Durchgangsöffnung herausgehoben und schaffen freien Durchgang.By turning the handwheel 1 to the left, the spindle 2 makes an increasing movement and removes the pressure on the sealing plate. Not drawn Blok kierungshebel and guide strips couple the seal plates to the spindle so that a displacement of the plate to the spindle can not occur. The plates are lifted out of the passage opening and create free passage.
SchließvorgangClosing process
Beim Rechtsdrehen des Handrades ι geht die Spindel 2 und die mit ihr fest verbündenen Teller nach unten bis vor die Durchgangsöffnung. Hier wird die Spindel von den nicht gezeichneten Blockierungshebehi freigegeben und macht eine Bewegung nach unten. Dabei treffen die Keile 3 auf die Druckstücke 22 und pressen die Abdichtungsteller fest auf ihre Sitze. Der Schieber ist geschlossen.When you turn the handwheel ι clockwise, the spindle 2 and the firmly allied with it go Plate down to in front of the passage opening. Here the spindle is released by the blocking lifting devices (not shown) and makes a movement down. The wedges 3 hit the pressure pieces 22 and press the sealing plates firmly onto their seats. The slider is closed.
