Abstract
1,204,127. Valves. BLAW KNOX Ltd. 23 Jan., 1968 [1 Feb., 1967], No. 4981/67. Heading F2V. [Also in Divisions Fl and G1] A float-actuated valve 23 in a tank 13 for use in priming a centrifugal pump (not shown), is gradually closed by the rising level of water drawn through a conduit 14 by the vacuum created by a sliding-vane vacuum-pump (not shown) connected to float chamber 19 through a flexible hose 33 and the valve 23. During closing of the valve 23, the float arm 21 is moved about pivot 25, but once the valve 23 is closed any further rise in the water level will cause the arm 21 to move about a pivot 26 against the action of a spring 30 until a valve 36 is opened to permit air to enter the chamber 19 and cause a lowering of the water level therein. The valve 23 comprises a leather or other appropriate disc or diaphragm stretched across a member 24, and co-operates with a perforated brass disc 31.
