ABSTRACT:
A voltage isolation device for controlling the flow of conductive liquid between a liquid supply source and a liquid destination source. The isolation device has an inlet connected to the supply source and has a yoke slide valve positionable along a pair of rods; one of the rods engages a slideable tube at the inlet to provide a liquid seal and the yoke slide valve may be positionable to slide the tube away from the rod to thereby provide a flow path for liquid through the tube and out the slide valve. A pair of seal assemblies each having axially spaced apart seals have formed sealing areas containing a non-conductive seal liquid which is capable of dissolving the conductive liquids being utilized. A scheme is provided to route arcs which result when the charged fluid is connected to the grounded fluid so as to locate the arc away from parts which could be damaged by it.
