Description
Die Erfindung stellt eine zweifach lösbare Rohrkupplung dar, welche speziell auf dem Gebiet der Hygiene in der Milchwirtschaft gegenüber der bestehenden DIN-Rohrverschräubung eine grundlegende Neuerung darstellt. Milch enthält Fett und Säuren. Beim Aufbereitungsprozeß wird Milch erhitzt, so daß Fett- und Säuredämpfe sich verflüchtigen. Insbesondere setzen sich Kondensate dieser Dämpfe in Ritzen und Spalten von Verschraubungen und Kupplungen bei unterbrochenen Leitungen ab und bilden dort unliebsame Brutstätten für gesundheitsschädliche Bakterien. Der größte Gefahrenherd ist stets die frei liegende Gummidichtung der bislang bekannten Rohrverschraubungen und -verbindungen. Man hat diesen Gefahrenherd erkannt und ist genötigt, Kupplungen und Verschraubungen täglich zu lösen und ,diese einem Reinigungsprozeß zu unterwerfen.The invention provides a double releasable pipe coupling which especially in the field of hygiene in the dairy industry compared to the existing one DIN pipe union represents a fundamental innovation. Milk contains fat and Acids. During the preparation process, milk is heated, so that fat and acid vapors to evaporate. In particular, condensates of these vapors settle in cracks and splitting of screw connections and couplings with interrupted lines from and form unpleasant breeding grounds for harmful bacteria there. The biggest The source of danger is always the exposed rubber seal of the previously known pipe screw connections and connections. This source of danger has been recognized and it is necessary to use clutches and to loosen screw connections daily and to subject them to a cleaning process.
Um diese nur einen Behelf darstellende Lösung zu ersetzen, wurde nachstehende Erfindung gemacht, welche i. eine geschlossene, querschnittgleiche Leitung schafft, 2. eine wesentliche Montageerleichterung darstellt, 3. eine Berührung der Flüssigkeit mit dem gegen Überdruck hermetisch abschließenden Gummiring vermeidet.To replace this only a makeshift solution, the following invention was made, which i. creates a closed line with the same cross-section, 2. makes assembly much easier, 3. avoids contact of the liquid with the rubber ring, which hermetically seals against excess pressure.
Die Kupplung besteht aus dem Vaterstück a, welches am Kegel außen den Gummiring c trägt, dem Mutterstück b, welches mittels Außengewinde durch die Überwurlmutter d gegen das Vaterstück a gezogen wird und mit diesem an den Stirnflächen bei e die metallische Dichtung gegen die Flüssigkeit bewirkt. Die zusätzliche hermetische Abdichtung gegen Überdruck wird von dem Mutterstück durch Druck auf den Gummiring c erzielt. Auf den Leitungsrohren g sind Gewinderinge h weich aufgelötet. Auf diese werden Vater- bzw. Mutterstück aufgeschraubt, wodurch bei leitungsgleichem Querschnitt eine stoßfreie Verbindung zwischen Vater- bzw. Mutterstück und Leitung hergestellt wird. Dichtigkeit gegen Überdruck wird durch einen elastischen Dichtring i gewährleistet, welcher so angeordnet ist, daß dieser außerhalb des Flüssigkeitsstromes liegt. Gesichert und gegen äußere Verschmutzung geschützt werden Vater- und Mutterstück sowie Gewindering durch die Gegenmutter k. The coupling consists of the male piece a, which bears the rubber ring c on the outside of the cone, the female piece b, which is pulled against the male piece a by means of an external thread through the union nut d and with this on the end faces at e causes the metallic seal against the liquid. The additional hermetic seal against excess pressure is achieved by the nut piece by pressing on the rubber ring c. Threaded rings h are softly soldered onto the conduit pipes g. The male and female parts are screwed onto these, whereby a joint-free connection between the male or female part and the cable is established with the same cross-section. Tightness against overpressure is ensured by an elastic sealing ring i, which is arranged so that it lies outside the flow of liquid. The male and female parts as well as the threaded ring are secured and protected against external contamination by the lock nut k.
