Description

Absperrschieber für Heißdampf mit in den Absperrkörper keilförmig eingesetzten Dichtungsplatten Zusatz zum Zusatzpatent 717 137 Im Patent 717 137 ist ein keilförmiger Absperrschieber für Heißdampf beschrieben, bei dem die in den Absperrkörper bzw. in :den Plattenkorb tingesietzten Dichtungsplatten durchgehend die gleiche Stärke aufweisen und bei dem. zwischen den Dichtungsplatten und dem Abspierrkörper Birne sich über die ganze Rückseite der Plattenerstreckende Unterlageschicht aus einem leicht verformbaren Werkstoff angeordnet ist.Gate valve for superheated steam with a wedge shape used in the shut-off seal plates addition to the patent of addition 717 137 In Patent 717 137 describes a wedge-shaped gate valve for superheated steam, wherein in the shut-off or in: continuously have the same thickness of the plate basket tingesietzten gasket sheets and wherein. Between the sealing plates and the Abspierrkörper pear is arranged over the entire back of the plates extending underlay made of an easily deformable material.

In dem Bestreben, den Schieber räumlich noch mehr zu verkleinern, verzichtet nun: der Erfindungsgegenstand auf die im Plattenkorb bisher zwischen den Absperrplatten vorgesehene mittlere Scheidmvand. Er gestaltet vielmehr den Plattenkorb in den mit den Dichtungsplatten zur Berühiiung kommenden Teilen so, daiß .er nur deren Umfang angepaßt, ,also zumeist rein ringförmig ausgebildet ist. Zwischen den beiden Dichtungsplatten befindet sich :erfindungsgemäß nur eine einzige Zwischenschicht aus ene_n leicht verformbaren Werkstoff, die der Keilform des Schiebers .entsprechend selbst keilförmig ausgestaltet ist.In an effort to make the slide even smaller spatially, now dispensed with: the subject of the invention on the one in the plate basket so far between Middle partition provided for the shut-off plates. Rather, he designed the plate basket in the parts that come into contact with the sealing plates in such a way that it is only the scope of which is adapted, that is to say is mostly purely ring-shaped. Between Both sealing plates are located: according to the invention, only a single intermediate layer Made of an easily deformable material that corresponds to the wedge shape of the slide itself is wedge-shaped.

Auf diese Weise wird erreicht, daß je de Dichtungsplatte nicht wie bei der Anordnung des Patents 717 13, ^ ihre eigene verformbare Unterlageschicht besitzt und dar diese nicht wieder durch eine miitt',ere Sche!c-eivand des Plattenkorbcs geschieden werden müssen. Viehhehr bildet nunmehr die erfin-. dungsgemäfiae alleinige verformbare Schicht zugleich die Scheidewand zwischen be_d en Dichtungsplatten, die bisher starr in den Plattenkorb eingearbeitet war. Diese eine verformbare. Schicht genügt völlig, um die Dichtungsplatten allen etwaigen Verzichungen oder Ungenauigkeiten des Gehäuses bzw. der Sitzringe sich anpassen zu lassen. Durch dcii Wegfall der bisherigen Trennwand des Plattenkorbes und den der einen verformbaren Werkstoffschicht wird eine nicht unerhebliche Materialersparnis und insbesondere eine bedeutende Verringerung in der Breite des Schieberkörpe rs und damit in der es ganzen Absperrschiebers erreicht.In this way it is achieved that each de sealing plate does not like in the arrangement of patent 717 13, ^ its own deformable backing layer owns and does not show this again by a middle, erect wall of the plate basket need to be divorced. Viehhehr now forms the inven-. dgemäfiae sole deformable layer at the same time the partition between the two sealing plates, which was previously rigidly incorporated into the plate basket. This one deformable. layer is completely sufficient to the sealing plates all possible waivers or To allow inaccuracies of the housing or the seat rings to be adapted. By dcii Elimination of the previous partition of the plate basket and the deformable one Material layer is a not inconsiderable material saving and in particular a significant reduction in the width of the Schieberkörpe rs and thus in the it reached the whole gate valve.

Die Dichtungsplatten werden nun im erfindungsgemäß gestalteten Plattenkorb dadurch festgehalten, daß die Stirnseiten dies dem Plattenumfang nachgebildeten Korbteils in an sich bekannter Weise mit nach innen gehenden Vorsprüngen versehen sind, die die über dein Umfang der Sitzringe hinaus vergrößerten Absperrplatten übergreifen. Durch diese an sich bekannte B:efestigunngsart können sich die Dichtungsplatten innerhalb kleinerer Grenzen im Plattenkorb verlagern und sich dadurch jeder Lageveränderung der Sitzringe anpassen. Zu erwähnen ist, daß die erfindungsgemäßien Vorsprünge auch vereinheitlicht sein können, indem, die Stirnseiten des Plattenkorbes bandartig nach innen verbreitert sind.The sealing plates are now in the plate basket designed according to the invention held by the fact that the end faces replicated this to the circumference of the plate Basket part provided in a known manner with inwardly extending projections are the shut-off plates that are enlarged beyond your circumference of the seat rings overlap. This known method of strengthening allows the sealing plates move within smaller limits in the plate basket and thereby any change in position adjust the seat rings. It should be mentioned that the projections according to the invention also can be unified by the end faces of the plate basket like a ribbon are widened inward.

Mit Hilfe dieser Anbringung der Dichtungsplatten im Plattenkorb wird ein verringerter Arbeitsaufwand erzielt, da auf diese Weise der bisher benötigte besondere Schraubrina für jede Dichtungsplatte in Wegfall kommt. der diese überdeckte und so die Sitzsichierung schuf. Das Einsetzen der Dichtungsplatten .erfolgt dadurch, daß der Plattenkorb aus zwei am besten in Richtung der Längsachse gefuhrten Teilen besteht, die nach Einfügen der Dichtungsplatten und der verformbaren Zwischenschicht zusammengeschraubt oder miteinander verschweißt werden.With the help of this attachment of the sealing plates in the plate basket a reduced amount of work achieved, since in this way the previously required special screw rina for each sealing plate is omitted. which covered this and so created the seat lock. The sealing plates are inserted by that the plate basket consists of two parts best guided in the direction of the longitudinal axis after inserting the sealing plates and the deformable intermediate layer screwed together or welded together.

Auf der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Abb. leinen Längsschnitt durch einen erfindungsgemäß gestalteten Schieber, während Abb. a den dagegen um go' versetzten Querschnitt entsprechend Linie A-B von Abb. i «ledergibt.In the figure, an embodiment of the invention is shown. It shows Fig. A longitudinal section through a slide designed according to the invention, while Fig. a shows the cross-section offset by go 'according to line A-B from fig.

Das Absperrschiebergehäuse a mit den Sitzringen b besitzt .einen Keilsch°--,eber, der aus den Dichtungsplatten rund dem Plattenkorb d besteht. Dieser ist, abgesehen vom Ansatz dl für die Spindel und vom Ansatz & in Rohrform für das Durchgangsmedium, in öffnungsstellung lediglich ringförmig, d.;, ausgestaltet. Die Stirnseiten d, dieser Ringform sind nach innen bundartig verbreitert, so daß sie die an ihrem Umfang nach innen abgesetzten Dichtungsplatten c übergreifen, deren Durchmesser größer ist als der der Sitzringe b. Zwischen den beiden Dichtungsplatten c liegt eine keilförmige Schichte aus verformbarem Material. Dadurch haben die Dichtungsplatten die Möglichkeit, in gewissem Umfang Lageveränderungen anzunehmen und so etwaige Ungenauigkeiten im Aufbau des Gehäuses oder Verziehungen dessen von sich aus auszugleichen.The gate valve housing a with the seat rings b has a wedge lock which consists of the sealing plates around the plate basket d. This one is apart from the approach dl for the spindle and from the approach & in tube form for the medium, in the open position only ring-shaped, d.;, designed. The end faces d, this ring shape are widened in a collar-like manner inward, so that they are at their circumference inwardly offset sealing plates c overlap, the diameter of which is larger is than that of the seat rings b. Between the two sealing plates c there is a wedge-shaped Layer of deformable material. This enables the sealing plates to to assume changes in position to a certain extent and thus any inaccuracies in the Compensate for the construction of the housing or any distortion of it on its own.
