Abstract

1525589 Automatic control for a sewage discharge valve WARTSILA AB OY 9 Oct 1975 [10 Oct 1975] 41369/75 Heading E1C [Also in Division G3] A sewage collecting tank 1 has an inlet 2 and is connected to a vacuum sewer 7 via a discharge valve 4, the control device for which valve comprises two floats 5, 6 and three auxiliary units 11, 12, 13, and operates pneumatically using atmospheric pressure and the reduced pressure in the vacuum sewer. When float 5 reaches its lowest position opening valve 9 to atmospheric pressure, valve 4 closes; when float 6 is raised opening valve 10, valve 21 opens thereby opening valve 4. In the circuit shown in Fig. 1 unit 13 is advantageous but not essential: in the circuit of Fig. 2 (not shown) unit 13 is essential.
