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.
