Abstract
1300161 Valves J GACHOT 6 March 1970 [7 March 1969 29 May 1969 4 Aug 1969] 10817/70 Heading F2V A butterfly valve has a body 4 provided with a duct 5 and adapted to be clamped between pipe flanges 2, and a closure disc 6 rotatable about an axis laterally offset from the disc. The closure surface 32 of the disc is spherical about a centre O where the duct axis intersects the axis of rotation. A sealing ring 14 constituting a seat for the disc projects into the duct and is held by a ring 16 having a seal 12 provided in the face which is opposed to the adjacent pipe flange 2. Projections 151, 152 on the body 4 and the ring 16 grip the ring 14 and provide concentric sealing zones. Both sealing rings 12 and 14 may be of P.T.F.E. Alternatively the sealing ring 14 may be of P.T.F.E. and reinforced with ground glassfibre or have a metal core coated with P.T.F.E. The stub shafts 7, 8 may be journalled in needle roller bearings Fig. 2 (not shown).
