Description
Verfahren zur Herstellung von Dichtringen für Absperrvorrichtungen Zusatz zum Patent 8301724 Das Patent 830 724 bezieht sich auf ein Verfahren zur Herstellung von in eine Nut eingesenktell Dichtringen deT Absperrvorrichtungen für Gais- und Flüssigkeitsleitungen, dessen wesentlicher Gedanke darin besteht, daß mit dem die. Einsenknut aufweisenden Absperrglied (Ventilteller, Klappe, Schieberkeil, Gehäusesitz od. #dgl.) ein Hilfsglied zusammengpespfannt wird, dais- mit einer Gegennut zum Formen der Dichtringkrone so,wie, mit zur Geggennut führenden Kanälen versehen ist, und, daß in die so, aus dem Absperriglied. und dem Hilfsglied gebildete Dichtringform unter Anwendung von Druck und Wärine, ein Preßstoff, insbesondere Kunstharzmasse, eingespritzt wird. Gemäß einer besonders zweckmäßigen AusfÜhrung deis, Verfah,rens nach dem Hauptpatenit zum Herstellen der Dichtringge von ",b#sp,eir#rsch,i#eb#erii mitt Doppelkeil wird der Schieberkeil, dessen beide Einsenknuten dureli einen oder nichrerle Querkanäle hintereinanderggeschaltet sind; zwischen zwei mit j-e einer zur Bildung der Dichtringkrone bestimmten Gegennut versehenen Hilfsgliedern eingespannt, wobei nur eines der beiden Hilfsglieder die Preßstoffkanäle enthält und durch dies-es Hilfsglied. hindurch der Preßstoff in, beide Dichtringformen eingespritzt wird. Zum Herstellein der Dichtringe der zugehöriggen Gehäuseisitze wird gemäß dem Hauptpatent auf einen der beiden die Ein senknutenenthaltünden Gehäuses-itze das mit der Gegeimut und den Proßstoffkanälen versehene Hilfsglied gelegt" wobeii dieses und der Gehlusesitz mittels eines durch den gegenüberliegenden Schieberstutzen, eingeführten Stempels aufeinandergepreßt und duirch den vom Hilfsglied abgedeckt.-eii andetren Sch#ieib,e-,rstuitz#en hindurch der PreUstoff Ü1 die Dichtringform eingelspritzt wi#r,d; der gle#iche Arbeitsgaing wird dann bei der Herstellung des zweiten Gehänsiesitzes wiederholt.Method for the production of sealing rings for shut- off devices Addendum to patent 8301724 The patent 830 724 relates to a method for the production of sealing rings countersunk in a groove deT shut-off devices for gas and liquid lines, the main idea of which is that with the. A shut-off member (valve disc, flap, valve wedge, housing seat or the like) with a sink groove is assembled, so that a counter groove for forming the sealing ring crown is provided with channels leading to the counter groove, and that in the so, from the barrier song. and the sealing ring shape formed in the auxiliary member is injected using pressure and heat, a molding material, in particular a synthetic resin compound. According to a particularly expedient embodiment of the process according to the main patent for producing the sealing rings from ", b # sp, eir # rsch, i # eb # erii with a double wedge, the valve wedge, the two grooves of which are connected one behind the other through one or non-transverse channels; clamped between two auxiliary members each provided with a counter-groove intended to form the sealing ring crown, only one of the two auxiliary members containing the press material channels and through this auxiliary member the press material is injected into both sealing ring molds According to the main patent, the auxiliary member provided with the counter-groove and the corrugated material ducts is placed on one of the two housing pieces that contain sunk grooves, "whereby this and the Gehlusesitz are pressed together by means of a stamp inserted through the opposite slide connector and covered by the auxiliary member. ieib, e-, rstui tz # en through the PreUstoff Ü1 the sealing ring shape is injected wi # r, d; the same work cycle is then repeated when making the second pod seat.
Vorliegende Erfindung geht von der nerieti Erkenntnis aus, daß dieses Verfabren und die mit ihm erzielbaren, Vorteile ebenfalls errelicht werdeii' ]#örmen, wenn man die Dichtringe _an Stelle aus einem Preißistoff, wie insbasondene Kuneharzmas#sen, aus, einem gieß- und spritzbu.en Metall, vorzugsweise einem korrosionsbeständigen inetallischen Werkstoff, herstellt.The present invention is based on the nerieti knowledge that this Procedure and the advantages that can be achieved with it are also achieved, if the sealing rings are used instead of a price material, such as synthetic resin compounds, made of a cast and spray-bonded metal, preferably a corrosion-resistant one inetallic material.
Da zur Heristellung der gespritzten IJi!chtrin&"e nur- verhäItn-i#smäßii.g geringe Maisisen werden, lassen sich dn wirtschaftlich vertretbarer Wei(se hochwertige metallische Weirkstoffe für die Di,cjhtr,in,-,le verwenden, die auch nach längeren Betrieb,s#ziciiten nicht zum Anro,stein der in Schließstiellung ainfeinanderliegend-en Dichtfläthen neigen. Auch die Dichtflächen aus Metall lassen sich im Wege des Pressens; unid Spritzens unter Druck und Hitze sehr sanber uild glatt herstellen, so, daß eine Nachbearbelitung im allgenuAnen nicht erfürderlich ist.Because for the production of the injected IJi! Chtrin & "e nur- behäItn-i # smäßii.g low corn iron, high-quality use metallic white substances for the Di, cjhtr, in, -, le, even after longer Operation, do not have to go to the stone that is lying one on top of the other in the closing position Flattening tend to be. The metal sealing surfaces can also be pressed; unid spraying under pressure and heat very gently and smoothly, so that post-processing is generally not necessary.
Der beim Pressen bzw. Spritzen angewendete Druck und die Temperatur des zur Verarbeftung ko#mmenden motallischen Dichtringwerksto,ffs richten sich nach der Beschaffenheit des benutzten Metalls-.The pressure and temperature used when pressing or spraying of the metal sealing ring material required for processing, ffs are based on the nature of the metal used.
Der technJische Anwendungsbereich der Metalldichtung ist der gleiche wie der der Preßstoiffdichtung nach,dern Hauptpatent.The technical field of application of the metal seal is the same like that of the pressed material seal, the main patent.
