Abstract

1350136 Valves FONDERIE ET ATELIERS DE MERSCH SA 24 Aug 1971 [25 Aug 1970] 39678/71 Heading F2V In a valve wherein a diaphragm 3 is moved relative to a seat 2 by a screwed spindle 5 a second diaphragm 8 is sealingly secured to the spindle to prevent fluid leakage in the event of failure of diaphragm 3. The diaphragm 8 is clamped between two rings 10 having diaphragm engaging curved faces by an enlarged member 6 and a nut 9. Alternatively a screw may be bonded in the diaphragm 8 which screw has an upwardly projecting screwed portion (12) for securing to a dished member fixed to the spindle and a tapped bore (13) for securing to a bolt (14) extending between the diaphragms. Diaphragm 3 is similarly constructed but has material extending over the tapped bore.
