Safe guard for protecting against back sucking of bath tub water over low-level mixed water inlet in combination with electronic bath tub armature, has flow-controlled-pipe disconnector-switching piston provided with auxiliary valve tube

摘要

The safe guard has a flow-controlled-pipe disconnector-switching piston (26) that is provided with a single-piece auxiliary valve tube (27). The auxiliary valve tube is arranged in a symmetry line. An indication unit is provided for recognizing the position of tubing separation a light signal. The indicating unit transmits the position of the flow-controlled switching piston by an electrical logic element and an electrical connecting line (47) from a pipe disconnector (23) to electronics of an armature.
