Abstract

759,492. Diaphragm valves. METROPOLITAN-VICKERS ELECTRICAL CO.. Ltd. March 2, 1954 [April 10, 1953], No. 9850/53. Class 135. A manually operated diaphragm valve comprises a casing defining a valve chamber 3 containing an annular valve seating 5, ducts 7, 8 communicating with the chamber on the inside and outside of the seating respectively, a flexible diaphragm 4 of rubber or a synthetic plastic, e.g. polythene, supported so as normally to extend parallel to and spaced from the seating with two self-aligning pressure pads 10, 12 abutting on opposite sides of the diaphragm, one 10 larger in diameter than the seating and the other 12 located within the seating and constrained against the diaphragm by a spring 11, and means such as the handle 9 and screwed spindle 13 operable at will from outside the casing for pressing the diaphragm against the seating 5. The diaphragm is clamped by screws between two casing parts 1, 2 of brass or stainless steel.
