Title: Improvements in Valves and in particular Footvalves
Inventor: DAGWELL HAROLD LLOYD
IPC: F04D29/70
Filed: 1967-03-09
Abstract: 1,187,241. Valves. HENRY SYKES Ltd. 11 March, 1968 [9 March, 1967], No. 11208/67. Heading F2V. [Also in Division G3] A valve, adapted to control the flow of water from within a perforated casing 10 to a suction line 14 of a suction pump, not shown, includes an L-shaped duct 12 which at its upper end communicates with line 14 and at its lower has a port 13 opening into the casing, a valve member 15 movable into and out of engagement with a seat formed on the port 13, and a valve 20 and float 21 for controlling the position of member 15 in dependence on the water level in the casing. With the float in its raised position, a flexible seating 25 is engaged by an upper conical valve member 31 and flexed upwardly, whilst a lower conical valve member 32 is raised from a similar, flexible seating 26, this resulting in suction being applied, from line 12 via ports 28 and 29, to the upper face of diaphragm 18 and hence in member 15 being raised from its seating and water entering the pump. With the float in its lowered position member 32 is made to engage its seating 26 whilst member 31 is detached from its seating 25, thereby permitting atmospheric pressure to enter chamber 30 and so seat member 15. A lost-motion coupling 34, 35 between the conical valve members 31 and 3 and the flexible nature of the seats 25 and 26 ensures that, during movement of the float, and hence of the valve 20, between the two extreme positions, the apertures in seats 25 and 26 are never opened simultaneously so preventing the possibility of atmospheric pressure being applied to the suction line 12.
