Description
<B>Rohrleitung aus elektrisch isolierendem Material</B> In. vielen Fällen ist es erwünscht oder not wendig, zwischen bestimmten Stellen von Rohrleitungen, die zum Transport von Flüs sigkeiten, Gasen oder Luft dienen, elektrische Impulse oder einen elektrischen Strom zur Betätigung von Nachrichtenübermittlungs-, Signal-, Mess-, Registrier- oder andern Vor richtungen oder zum Antrieb von elektrischen Motoren zu leiten.
Bisher wurden hierfür von den Rohr leitungen (worunter auch Schlauchleitungen zu verstehen sind) unabhängig hergestellte und von diesem separat verlegte elektrische Leiter verwendet.
Die Erfindung betrifft nun eine aus einem elektrisch isolierenden Material bestehende Rohrleitung, die sich dadurch kennzeichnet, class in mindestens einem parallel zur Rohr achse verlaufenden Teil der Rohrwandung ein elektrischer Leiter vorgesehen ist.
Auf der beiliegenden Zeichnung sind drei Ausführungsbeispiele des Erfindungsgegen standes veranschaulicht.
Fig.1 ist ein Längsschnitt durch einen Abschnitt einer Rohrleitung nach der ersten Ausführungsform; Fig.2 ist ein Querschnitt durch diese Rohrleitung; Fig.3 und 4 sind Querschnitte durch Rohrleitungen nach der zweiten und nach der dritten Ausführungsform.
Die Rohrleitung a nach Fig.1 und 2 be steht aus einem thermoplastischen Kunststoff, wie z. B. Polyäthylen, Polyvinyl-Chlorid oder dergleichen, obwohl sie auch aus einem andern elektrisch isolierenden Material, wie z. B. Gummi, bestehen könnte. Sie wird zweck mässig nach dem, sogenannten Strangpressver- fahren hergestellt. Im gleichen Arbeitsgang werden an zwei einander gegenüberliegenden, parallel zur Rohrachse verlaufenden Teilen der Rohrwandung elektrische Leiter b vor gesehen, die, wenn die Rohrleitung verlegt ist, im Hinblick auf die eingangs erwähnten Zwecke, zur Stromführung verwendet werden können.
Gegebenenfalls könnte die Rohrlei tung a mit einem einzigen Leiter<I>b</I> versehen sein. In diesem Falle müsste zur Stromfüh rung die Erde als zweiter Leiter benützt werden. Es wäre aber möglich, in der Rohr wandung eine grössere Zahl gleichmässig rings herum verteilter Leiter vorzusehen.
Beim Ausführungsbeispiel nach Fig. 3 sind die elektrischen Leiter b in parallel zur Rohr achse verlaufenden Wulstteilen ai der Rohr wandung eingebettet.
Die Rohrleitung gemäss Fig. 4 weist, ähn lich wie die Rohrleitung nach Fig.3, hohle Wulstteile a2 auf, die aber in der Längs richtung geschlitzt sind, so dass die elektri schen Leiter b hier nachträglich in diese Wülstteile eingelegt werden können. Der Zweck dieser Leiter ist aber der gleiche, näm lich der der Stromführung bei verlegter Rohr leitung im Hinblick auf die eingangs er wähnten Zwecke.
Der Hauptvorteil der oben beschriebenen Rohrleitungen liegt darin, dass mit dem Ver legen derselben im gleichen Arbeitsgang auch die zur Stromführung bestimmten, elektri schen Leiter verlegt werden, ohne dass für diese Leiter besondere Mittel für das Anord nen derselben unter, auf oder über dem Boden notwendig sind.
Anstatt Drähte als elektrische Leiter kön nen auch z. B. Litzen oder Bänder verwen det werden.
Der Erfindungsgegenstand ist als Rohr leitung bezeichnet worden. In den meisten Fällen wird diese Leitung biegsam sein, so dass unter dieser Bezeichnung auch eine Schlauchleitung zu verstehen ist.
<B> Pipeline made of electrically insulating material </B> In. In many cases, it is desirable or necessary between certain points of pipelines that are used to transport liquids, gases or air, electrical pulses or an electrical current to operate communications, signals, measurement, registration or other before directions or to drive electric motors.
So far this was done by the pipelines (which also includes hose lines) independently manufactured and used separately from this electrical conductor.
The invention now relates to a pipe consisting of an electrically insulating material, which is characterized in that an electrical conductor is provided in at least one part of the pipe wall running parallel to the pipe axis.
On the accompanying drawing, three embodiments of the subject invention are illustrated.
Fig. 1 is a longitudinal section through a portion of a pipeline according to the first embodiment; Fig. 2 is a cross section through this pipeline; 3 and 4 are cross-sections through pipelines according to the second and third embodiment.
The pipe a according to Figure 1 and 2 be made of a thermoplastic material, such as. B. polyethylene, polyvinyl chloride or the like, although they are also made of another electrically insulating material, such as. B. rubber, could exist. It is expediently produced according to the so-called extrusion process. In the same operation, electrical conductors b are seen on two opposing, parallel to the pipe axis extending parts of the pipe wall before, which, when the pipeline is laid, can be used to conduct current with regard to the purposes mentioned above.
If necessary, the pipeline a could be provided with a single conductor <I> b </I>. In this case, earth would have to be used as a second conductor to conduct electricity. However, it would be possible to provide a larger number of conductors evenly distributed around the pipe wall.
In the embodiment according to FIG. 3, the electrical conductors b are embedded in bead parts ai of the pipe wall running parallel to the pipe axis.
The pipeline according to FIG. 4 has, similar to the pipeline according to FIG. 3, hollow bead parts a2, but these are slotted in the longitudinal direction so that the electrical conductors b can be inserted into these bead parts afterwards. The purpose of this conductor is the same, namely that of the current conduction when the pipe is laid with regard to the purposes mentioned above.
The main advantage of the pipelines described above is that when they are laid, the electrical conductors intended for carrying current are also laid in the same operation, without the need for special means for arranging them under, on or above the floor are.
Instead of using wires as electrical conductors, B. strands or tapes are used.
The subject of the invention has been designated as a pipe line. In most cases, this line will be flexible, so that this term also includes a hose line.
