Abstract

1447303 Valves BRAUKMANN ARMATUREN AG 23 April 1974 [23 April 1973] 17686/74 Heading F2V In an anti-syphon valve normal flow is from an inlet at the top of the valve via an inlet check valve 78 and an outlet check valve 104 which define an intermediate chamber between them. The inlet check valve comprises a closure member 90 which seats on an annular member 56 carried by a flexible diaphragm 60 attached to the valve body. Should pressure at the outlet exceed that at the inlet, the inlet check valve closes and the diaphragm moves upwards so that a depending flange 68 on the annular member 56 lifts from a rubber seating 34 mounted in the valve body to connect the intermediate chamber to a vent passage 28. This action is assisted by a spring 102 acting between the annular member 56 and a collar 42 attached to the valve body.
