Abstract
Description
Die Erfindung betrifft eine Blindkupplung, die axial schließt und kompatibel ist mit einer symmetrischen Schlauchkupplung aus zwei Kupplungshälften, die je aus einem Schlauchstutzen und einem auf dem Schlauchstutzen drehbar angebrachten Knaggenring bestehen. Alternativ kann bei diesem Kupplungstyp eine Hälfte einteilig als sogenannte Festkupplung ausgeführt sein, weshalb die Blindkupplung in ihrer zweiteilige Form auch dazu kompatibel ist.The The invention relates to a blind coupling which closes axially and is compatible is with a symmetrical hose coupling of two coupling halves, the each of a hose nozzle and a rotatable on the hose nozzle attached Knaggenring exist. Alternatively, in this type of clutch a half be made in one piece as a so-called solid coupling, which is why the dummy coupling in its two-part form is also compatible.
Blindkupplungen sind beispielsweise aus dem Feuerwehrwesen bekannt. Sie sind kompatibel zu Schlauchkupplungen, deren symmetrische Kupplungshälften Knaggenringe aufweisen, welche gegenüber den jeder Hälfte zugeordneten Schlauchstutzen drehbar sind und deren Knaggen mit eine Steigung aufweisenden Leisten des Knaggenringes der jeweils anderen Kupplungshälfte bajonettverschlussartig in Eingriff gebracht werden können. Die Drehung der Knaggenringe bewirkt eine axiale Annäherung der Schlauchstutzen, so daß in deren Stirnseiten angeordnete Dichtungsringe ohne gegenseitige Drehung axial gegeneinander gepreßt werden. Die zur Schlauchkupplung kompatible Festkupplung vereinigt außer den Kraft übertragenden Elementen Knaggen und Leisten auch den Dichtungsring in der einteiligen Kupplungsform und gewährleistet mit einem drehbaren Knaggenring der Gegenkupplung das Funktionsprinzip. Die Blindkupplung ist eine Variante der Schlauchkupplung, wobei der Schlauchstutzen durch einen kupplungsseitig identisch ausgebildeten Blinddeckel mit geschlossenem Boden ersetzt ist. Blindkupplungen dienen zum Verschließen nicht benötigter Leitungsanschlüsse oder aber auch nur als Schutzelement an nicht druckbeaufschlagten Leitungen.Blank Caps are known for example from the fire department. They are compatible too Hose couplings whose symmetrical coupling halves are knurled rings have, which opposite every half associated hose nozzle are rotatable and their catches with a slope having strips of the Knaggenringes each other coupling half can be engaged in a bayonet-like manner. The rotation the Knaggenringe causes an axial approach of the hose nozzle, so that in whose end faces arranged sealing rings without mutual rotation axially pressed against each other become. The compatible to the hose coupling fixed coupling united except transmitting the power Elements catches and strips also the sealing ring in the one-piece Coupling shape and guaranteed with a rotatable Knaggenring the counter-coupling the operating principle. The dummy coupling is a variant of the hose coupling, wherein the hose nozzle by a clutch side identically formed Blind cover with closed bottom is replaced. Blank Caps do not serve for closing needed cable connections or even only as a protective element on non-pressurized lines.
Derartige als System „Storz" lange bekannte und hinsichtlich der Anschlußmaße und Ausführungsanforderungen beispielsweise in DIN 14301 ff. genormte Kupplungen schließen auch Blindkupplungen für oben angeführte Anwendungsfälle in der Gestalt ein, daß zum Verschließen hauptsächlich Wasser führender Leitungen Dichtungen für Druck- und/oder Saugbetrieb verwendet werden oder daß für die Schutzfunktion trockener Leitungen in den Boden des Deckels gebohrte Kontrollöcher mit Durchmesser von ca. 4 mm verhindern, daß sich bei Ventilleckage in der Leitung ein Druck aufbauen kann oder bei versehentlicher Ventilöffnung ein solcher angezeigt wird, um so den Bediener nicht zu gefährden. Es gibt aber auch Situationen in der Praxis, wo die Blindkupplung – zwar nicht gleichzeitig – vorteilhaft beide der beschriebenen Funktionen erfüllen können sollte, so z.B. als Schutzelement an der Festkupplung am Abgang eines druckseitig eingesetzten Absperrventils an einer Feuerwehrpumpe, die wiederum in bestimmten Zyklen auf ihre Ansaugtauglichkeit geprüft werden muß, wobei im Falle einer Undichtigkeit am Ventil die Blindkupplung die hermetische Abdichtung übernimmt.such as a system "Storz" long known and in terms of connection dimensions and execution requirements For example, in DIN 14301 ff. standardized couplings also include Blind couplings for cited above use cases in the shape of that close mainly Water leader Lines seals for Pressure and / or suction can be used or that for the protection function dry holes drilled into the bottom of the lid Diameter of about 4 mm prevent that at Ventilleckage in the line can build up a pressure or in case of accidental valve opening such is displayed so as not to endanger the operator. It But there are also situations in practice, where the blind coupling - not at the same time - both advantageous fulfill the described functions should, e.g. as protective element on the fixed coupling at the outlet of a pressure side used shut-off valve on a fire pump, which in turn be tested for their suitability for suction in certain cycles must, where in the case of a leak at the valve, the blind coupling the hermetic Sealing takes over.
Der Erfindung liegt die Aufgabe zugrunde, eine Blindkupplung so zu modifizieren, daß in der durch sie verschlossenen Leitung Druckaufbau vermieden oder zumindest erkennbar angezeigt, Vakuumdichtigkeit jedoch gewährleistet wird.Of the Invention is based on the object to modify a dummy coupling so that in the line closed by them avoided pressure buildup or indicated at least recognizable, however, ensures vacuum tightness becomes.
