ABSTRACT:
A simplified and easily operative flow control mechanism for an automatic pressure reducing equipment characterized in that a pressure detector detects such an inconvenient condition that a pressure of high pressure sample water is extremely reduced on an inlet line of a pressure reducing mechanism until the pressure reducing mechanism becomes inoperable, and that pressure-reduced sample water can bypass a flow control valve being provided on an outlet line of the pressure reducing mechanism by an automatic opening operation of an electromagnetic control valve so as to feed a predetermined amount of the sample water to an analysis system.
