Abstract
This automatic valve controls the flow of fluid filling a reservoir and closes when the liquid reaches a predetermined level. The closure is progressive and allows the operator to turn off the supply and clear liquid in the supply pipe when it is noted that the valve has automatically reduced the flow. If the operator does not notice the flow reduction then the valve completely closes after a further reduction in flow rate. A final stage is the provision of an additional throttle valve which operates if any components in the main valve fail. A first float (51) pivots about an axis (18) as the liquid level rises and brings the main valve head (22) on to its seat (40) by pivoting arm (20). A hole in the centre of the main valve forms a seat for a second valve washer (23) which is carried on a central shaft (24) perpendicular to the valve heads. This shaft passes through the washer (23) leaving a clearance, but has a shoulder which completely closes off the passage eventually. The closing of the second and third valves is accomplished by additional pressure on the arm (20) from a lever (60) operated by a second float (55) which only operates at higher liquid levels. This second float also releases the spring (67) loaded butterfly safety valve (65) if the other valves should fail.
