Controlling efflux from storm water interception tanks of waste water treatment plants, employs float-operated mechanical control system which adjusts inlet and outlet valves

摘要

The float (2) operates rods (13, 14) connected to the inlet and outlet gate valves (7, 8) via the parallel guidance mechanism (12) and its control levers (5, 6). The connection to the inlet gate valve passes through a heavy duty roller guidance assembly (9) located above it. The equipment constitutes a mechanical control circuit. Rod (13, 14) adjustments vary the efflux quantity. By adjustment of the roller guide (9), larger water pressures and quantities are regulated.
