Abstract

1446704 Valves NATIONAL VULCAN ENG INSURANCE GROUP Ltd 12 Oct 1973 [29 July 1972 (2) 35588/72 and 35590/72 Heading F2V A spring-biased relief valve is provided with a cap-shaped closure member 24 which fits over and seats upon a tubular inlet 12 such that after the initial opening of the valve due to pressure in the inlet, the momentum of the fluid flowing in a U-turn around the tubular inlet and closure member gives an extra opening force to the member. A diaphragm 31 seals the spring from the flow passages. A handle 20 is provided for testing purposes and the member may be additionally actuated by a thermally responsive element 34. The sealing ring 26 attached to the closure member is the same as that described in Specification 1,446,705. Sealing is effected by a metal to metal contact between member and seat as well as between the sealing ring and the seat. A sealing ring is described which does not have a step on the internal flange.
