Abstract
Gegenstand der Erfindung ist eine Schottverschraubung für eine fluidführende Leitung zur Schaffung eines Durchganges durch eine Schottwand, umfassend einen Tubus (10) und einen am Tubus (10) angebrachten Verschraubungskörper (11), wobei am Verschraubungskörper (11) eine sich radial erstreckende Stirnwand (13) zur Anlage des Verschraubungskörpers (11) an der Schottwand ausgebildet ist und wobei an dem Tubus (10) ein Außengewinde (14) zur Aufnahme einer Kontermutter (15) vorgesehen ist, so dass die Kontermutter (15) gegen den Verschraubungskörper (11) schraubbar ist und dabei die Schottwand zwischen der Kontermutter (15) und dem Verschraubungskörper (11) einspannt. Eine Schottverschraubung zu schaffen, die auch bei Erschütterungen oder Vibrationen zuverlässig hält wird dadurch erreicht, dass an der Stirnfläche (13) des Verschraubungskörpers (11) Mittel zur Erhöhung der Oberflächenrauigkeit vorgesehen sind.The invention relates to a bulkhead fitting for a fluid-carrying line to create a passage through a bulkhead, comprising a tube (10) and a fitting (11) attached to the tube (10), wherein a radially extending end wall (13) on the fitting body (11) ) is formed on the bulkhead (10) for receiving the screwing body (11) and wherein an external thread (14) for receiving a lock nut (15) is provided on the tube (10), so that the lock nut (15) can be screwed against the screwing body (11) is while the bulkhead between the lock nut (15) and the fitting body (11) clamped. To provide a bulkhead fitting that reliably holds even with vibration or vibration is achieved in that on the end face (13) of the Verschraubungskörpers (11) means are provided to increase the surface roughness.
Description
Die vorliegende Erfindung betrifft eine Schottverschraubung für eine fluidführende Leitung zur Schaffung eines Durchganges durch eine Schottwand gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a bulkhead fitting for a fluid-carrying conduit for creating a passage through a bulkhead according to the preamble of claim 1.
Aus der
In der Praxis kann es aufgrund von Erschütterungen und Vibrationen dazu kommen, dass sich die Kontermutter löst und die Schottverschraubung nicht länger zuverlässig an der Schottwand gehalten wird.In practice, due to vibration and vibration, the locknut may loosen and the bulkhead fitting may no longer be reliably held to the bulkhead.
Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Schottverschraubung der eingangs genannten Art zu schaffen, die auch bei Erschütterungen oder Vibrationen zuverlässig hält.On this basis, the present invention, the object of the invention to provide a bulkhead fitting of the type mentioned above, which reliably holds even with vibration or vibration.
Als technische Lösung dieser Aufgabe wird erfindungsgemäß eine Schottverschraubung mit den Merkmalen des Anspruches 1 vorgeschlagen. Vorteilhafte Weiterbildungen dieser Schottverschraubung sind den Unteransprüchen zu entnehmen.As a technical solution to this problem, a bulkhead with the features of claim 1 is proposed according to the invention. Advantageous developments of this bulkhead connection can be found in the dependent claims.
Eine nach dieser technischen Lehre ausgebildete Schottverschraubung hat den Vorteil, dass aufgrund der Oberflächenrauhigkeit einzelne hervorragende Teile der Stirnfläche in die Schottwand gedrückt werden und somit ein entsprechendes Verdrehen und damit ein Lösen des Verschraubungskörpers erschwert oder gar verhindert wird. Analoges gilt bei einer Ausbildung der Konterfläche der Kontermutter mit einer erhöhten Oberflächenrauigkeit.A trained according to this technical teaching bulkhead fitting has the advantage that due to the surface roughness individual outstanding parts of the end face are pressed into the bulkhead and thus complicates a corresponding twisting and thus loosening the Verschraubungskörpers or even prevented. The same applies to a design of the counter surface of the lock nut with an increased surface roughness.
Im Ergebnis wird also der Verschraubungskörper und/oder die Kontermutter nicht nur kraftschlüssig, sondern auch formschlüssig an der Schottwand gehalten, was ein ungewolltes Lösen der Verschraubungskörpers und/oder der Kontermutter verhindert, zumindest aber erschwert.As a result, therefore, the fitting body and / or the lock nut are not only frictionally, but also positively held on the bulkhead, which prevents unwanted loosening the Verschraubungskörpers and / or the lock nut, but at least more difficult.
Dabei hat es sich als vorteihaft erwiesen, die sich radial erstreckende Stirnfläche und/oder die sich radial erstreckend Konterfläche mit einer an sich bekannten Rändelung zu versehen. Eine solche Rändelung hat den Vorteil, dass diese schnell und einfach an der Stirnfläche, bzw. an der Konterfläche angebracht werden kann und gleichzeitig eine Oberfläche mit einer erhöhten Oberflächenrauigkeit schafft.It has proven to be vorteihaft to provide the radially extending end face and / or the radially extending counter surface with a known knurling. Such a knurling has the advantage that it can be attached quickly and easily to the end face or to the counter face and at the same time creates a surface with an increased surface roughness.
In einer alternativen Ausführungsform kann Anstelle der Rändelung oder zusätzlich zur Rändelung eine Riffelung eingesetzt werden, die sich vorteilhafterweise aus einer Anzahl auf der Stirnfläche und/oder der Konterfläche radial ausgerichteter Riefen zusammensetzt.In an alternative embodiment, instead of the knurling or in addition to the knurling, corrugation can be used, which advantageously comprises a number of grooves aligned radially on the end face and / or the counter face.
In einer ganz anderen, ebenfalls bevorzugten Ausführungsform ist zwischen der Stirnfläche und der Schottwand und/oder zwischen der Konterfläche und der Schottwand eine Fächerscheibe vorgesehen. Dies hat den Vorteil, dass sich beim Anziehen der Schottverschraubung die aixial von der Fächerscheibe abstehenden Fächer einerseits in den Verschraubungskörper, bzw. in die Kontermutter und/oder andererseits in die Schottwand teilweise hineindrücken und so in Umfangsrichtung einen Formschluss herstellen, der ein Verdrehen des Verschraubungskörpers und/oder der Kontermutter verhindert, zumindest aber erschwert.In a completely different, likewise preferred embodiment, a fan disc is provided between the end face and the bulkhead and / or between the counter surface and the bulkhead. This has the advantage that, when tightening the bulkhead fitting, the compartments projecting aixially from the fan disk partly press into the fitting body, or respectively into the lock nut and / or the bulkhead, thus producing a form fit in the circumferential direction, which causes the fitting body to rotate and / or the lock nut prevents, but at least more difficult.
Weitere Vorteile der erfindungsgemäßen Schottverschraubung ergeben sich aus der beigefügten Zeichnung und den nachstehend beschriebenen Ausführungsformen. Ebenso können die vorstehend genannten und die noch weiter ausgeführten Merkmale erfindungsgemäß jeweils einzeln oder in beliebigen Kombinationen miteinander verwendet werden. Die erwähnten Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter. Es zeigen:Further advantages of the bulkhead fitting according to the invention will become apparent from the accompanying drawings and the embodiments described below. Likewise, according to the invention, the above-mentioned features and those which are still further developed can be used individually or in any desired combinations with one another. The mentioned embodiments are not to be understood as an exhaustive list, but rather have exemplary character. Show it:
