Abstract

1356707 Valves SIR W H BAILEY & CO Ltd 5 Jan 1973 [21 Jan 1972] 3008/72 Heading F2V A rotary ball valve for use in a fire-risk area includes two seals, firstly an annular plastic or elastomeric seal 47 supported by a first recess 45 in the valve casing part 7 and pressing against the ball 18 and secondly a metallic seal ring 60 supported by a second recess 46 in the casing part and terminating in a circular edge 62 for sealing contact with the ball upon failure of the elastomeric seal. The metallic ring is preferably of stainless steel or should have a thermal expansion coefficient not less than that of the casing part 7. The seal 47 may be made of PTFE material with a reinforcing filling. Excess pressure in the valve, particularly coupled with loss of the packing material 34, is contained by the shaft 20 rising to press the collar 37 against the surface of the recess 36.
