Abstract

1. A method of controlling a pipe isolator in dependence upon a pressure difference predetermined at a comparison station, the pressure difference resulting from a comparison between the pressures on the inflow side and outfow side, in an apparatus for preventing reflux from a discharge line, a constant safety value being added to the pressure in the discharge line, the isolator permitting throughflow upon the predetermined pressure difference being reached, the throughflow being interrupted again upon the pressure difference being undershot, the pressure difference decreasing again only as a result of termination of the throughflow, characterized in that the pressure is reduced on the discharge side for the duration of the throughflow and is built up again upon the termination thereof and the resulting pressure is compared with the pressure on the inflow side.
