Abstract

A tidal outfall valve comprises a chamber having an inlet (6) and an oulet (8). One wall of the chamber comprises a diaphragm (10) which can move into contact with a seat (9) to isolate the outlet from the inlet. A weight (18) provided on the diaphragm biasses the diaphragm into this closed position. In use, the valve is closed at high tide by the hydrostatic pressure of sea water acting on the diaphragm. At low tide, the hydrostatic pressure in the inlet to the valve lifts the diaphragm to allow flow to take place from the inlet to the outlet. The valve has uses in other situations where flow is to be controlled in response to the relative pressures at the inlet and in a body of fluid in which the valve is immersed.
