Description

Gegenstand der Erfindung ist ein Dichtring, der besonders zur Abdichtung gegen hohe Drücke und bei hohen Temperaturen geeignet und bestimmt ist. Bei derartigen Dichtringen werden bisher als Füllmittel Faserstoffe, wie Asbest, angewandt. Die Dichtwirkung solcher Füllstoffe ist aber nur bei verhältnismäßig niedrigen Temperaturen befriedigend. Steigt die Erhitzung der abzudichtenden Teile dagegen stark an, dann ergeben derartige Füllstoffe bei hohen Wärmegraden nicht mehr genügende Abdichtung.The invention relates to a sealing ring, which is particularly used for sealing is suitable and intended against high pressures and at high temperatures. With such Sealing rings have hitherto been used as a filler, fibrous materials such as asbestos. the Such fillers only have a sealing effect at relatively low temperatures satisfactory. If, on the other hand, the heating of the parts to be sealed increases sharply, then Such fillers no longer provide an adequate seal at high degrees of heat.

Ferner ist es bekannt, für Abdichtungszwecke Hohlringe aus Metall mit einer Flüssigkeitsfüllung; beispielsweise Kupferrohr mit Ätherfüllung, zu verwenden. Diese Dichtringe sind jedoch bei hohen Temperaturen nicht brauchbar, da bei ihnen die Gefahr der Explosion besteht. Außerdem haben sie den Nachteil, daß eine einzige undichte Stelle, die beispielsweise nach dem Einfüllen der Flüssigkeit beim Abschließen übrigbleiben kann, die angestrebte Dichtwirkung völlig vereitelt. Es bietet auch große Schwierigkeiten, an Dichtringen einen dicht verschließbaren Hohlraum zu schaffen und ihn mit Flüssigkeit anzufüllen.It is also known to use hollow rings made of metal for sealing purposes with a liquid filling; for example copper pipe with ether filling to use. However, these sealing rings cannot be used at high temperatures because they there is a risk of explosion. They also have the disadvantage that a single leak, for example after filling the liquid when closing can remain, the desired sealing effect completely thwarted. It also offers great difficulty in creating a tightly closable cavity on sealing rings and fill it with liquid.

Gemäß der Erfindung wird nun statt Faserstoffen und Flüssigkeiten als Füllmittel ein mineralischer Stoff verwendet, der zunächst in Gestalt eines feinen Pulvers in den Mantel derart gepreßt w=ird, daß er eine kompakte Masse bildet, und es wird ein solcher mineralischer Stoff verwendet, der vermöge eines Öl-, Fett-, Bitumengehalts oder eines Gehalts an gebundenem, vorzugsweise chemisch gebundenem Wasser bei hohen Temperaturen anstatt hinter der Wärmeausdehnung des Metalls zurückzubleiben oder gar zu sintern, das Bestreben hat, sich auszudehnen.According to the invention, instead of fibers and liquids a mineral substance is used as a filler, initially in the form of a fine powder is pressed into the jacket in such a way that it forms a compact mass, and such a mineral substance is used, which by virtue of an oil, fat, Bitumen content or a content of bound, preferably chemically bound Water at high temperatures instead of lagging behind the thermal expansion of the metal or even to sinter, which strives to expand.

Besonders geeignet ist Talkum, z. B. der als Speckstein bekannte Talk, der die Eigenschaft hat, daß er in Pulverform zu einem Körper gepreßt,bei Erwärmung bis etwa q.oo° wächst bzw. sich ausdehnt in solchem Maße, daß er, als Dichtmittel angewandt, bei solch hohen Temperaturen noch einen gasdichten Abschluß bis zu Drücken von 5o atü und mehr gewährleistet.Talc is particularly suitable, e.g. B. the talc known as soapstone, which has the property that it is pressed into a body in powder form when heated up to about q.oo ° grows or expands to such an extent that, as a sealant applied, at such high temperatures still a gas-tight seal up to pressures from 5o atm and more guaranteed.

Dieser Füllstoff ergibt an sich schon eine verhältnismäßig gute Wärmeableitung. Zur Erhöhung dieses Wärmeableitungsv ermögens wird ihm zweckmäßig Graphitpulver beigemischt.This filler in itself results in relatively good heat dissipation. Graphite powder is useful to increase this heat dissipation mixed in.

Der Blechmantel kann aus dünnem Kupfer- oder Weicheisenblech bestehen. Er wird vorzugsweise geschlossen gehalten. Bei besonderen Anordnungen, beispielsweise dann, wenn der Dichtring in entsprechenden Ausnehmungen versenkt angeordnet wird, kann der Mantel auch in bekannter Weise einseitig offen sein.The sheet metal jacket can consist of thin copper or soft iron sheet. It is preferably kept closed. With special arrangements, for example when the sealing ring is arranged sunk in corresponding recesses, the jacket can also be open on one side in a known manner.

Zwei Ausführungsbeispiele sind in der Zeichnung dargestellt nebst einem besonderen Anwendungsbeispiel.Two exemplary embodiments are shown in addition in the drawing a special application example.

Fig. i zeigt einen Querschnitt; Fig. 2 einen Grundriß eines Dichtringes, bei dem ,die Füllmasse a in einem dünnen Blechring e von U-förmigem Querschnitt liegt, Fig. 3 zeigt als zweites Ausführungsbeispiel im Querschnitt einen ringwulstförmigen Dichtring, bei dem die Dichtmasse a in einem über seinen ganzen Umfang geschlossenen oder nahezu geschlossenen dünnen Metallring untergebracht wird; Fig. q. ist eine Draufsicht zu Fig. 3.Fig. I shows a cross section; Fig. 2 is a plan view of a sealing ring, in which, the filling compound a in a thin sheet metal ring e of U-shaped cross-section is, Fig. 3 shows as a second embodiment in cross section an annular bead-shaped Sealing ring in which the sealing compound a is closed over its entire circumference or almost closed thin metal ring is housed; Fig. Q. is a Top view of FIG. 3.

Bei dieser Ausführungsform wird zweckmäßig die Fuge o, die entweder stumpf gestoßen oder auch überplattet sein kann, so angeordnet, daß sie bei angewandter Dichtung von einer der Dichtflächen überdeckt wird.In this embodiment, the joint o, either butt butted or can be overplated, arranged so that they are applied when Seal is covered by one of the sealing surfaces.

Fig.5 zeigt ein solches Anwendungsspiel im Längsschnitt.5 shows such an application game in longitudinal section.

Der Dichtring ist hierbei zwischen zwei Endflächen von Rohren d bzw. c untergebracht und wird in an sich bekannter Weise durch eine Überwurfhülse f und eine in ein Innengewinde derselben eingeschraubte Ringmutter g zusammengedrückt.The sealing ring is here between two end faces of pipes d or c housed and is in a known manner by a sleeve f and a ring nut g screwed into an internal thread thereof is compressed.
