Description

BESCHREIBUNG
der "^elektrisch isolierten Rohrverschraubung"DESCRIPTION
the "^ electrically insulated pipe union"

"^el"^ el

Elektrisch isolierte Rohrverschraubung, die aus zwei Drehteilen besteht. Diese Drehteile haben auf der Innenseite je ein Anschlußrohrgewinde, auf der Außenseite Schlüsselflächen. Das rechte gelegene Werkstück (Nr. 2) kann auch innen glatt ausgebildet sein, üb »in Rohr aufzunehmen. In das Werkstück Nr. 2 sind Nuten eingefräst, die die Isolierringe aufnehmen.Electrically insulated pipe union consisting of two rotating parts. These turned parts have on the inside one connection pipe thread each, on the outside wrench flats. The workpiece on the right (No. 2) can also be smooth on the inside, to be accommodated in a tube. In the workpiece no. 2 are milled grooves that accommodate the insulating rings.

Die Verschraubungen Nr. 1 und Nr. 2 werden zusamsaengeschraubt durch die Überwurfmutter Nr. 3. Die Dichtigkeit der Verschraubung wird dadurch erreicht, daß über dem inneren Isolierring ein "O-Ring" angebracht ist.The screw connections No. 1 and No. 2 are screwed together through the union nut no. 3. The tightness of the screw connection is achieved by placing over the inner insulating ring an "O-ring" is attached.

Die Überwurfmutter sitzt auf dem äußeren Isolierring, der in die Verschraubung Nr. 1 eingepaßt ist. Durch diese Art der Verbindung wird der Stromfluß von dem Werkstück 1 in das Werkstück 2 verhindert.The union nut sits on the outer insulating ring, which is fitted into screw connection no. Through this kind of Connection, the flow of current from workpiece 1 into workpiece 2 is prevented.
