Abstract

1289935 Valves COMMISSARIAT A L'ENERGIE ATOMIQUE 20 April 1971 [20 April 1970] 10232/71 Heading F2V A valve for use with corrosive liquids comprises a body 1, a conical closure 4 formed with a groove 5 on its lower surface and mounted on a hollow rod 25 having orifices 8 for passage of the liquid, a liquid collector 7 connected to the rod beneath the orifices, and a metal bellows 10 surrounding the rod with its ends connected to a collar 25 and a cap 11, A knob 16 in screwed engagement with the cap displaces the rod which is held against rotation by a key 15. Any liquid which leaks into the body may be drained through a tube 19 and cock 20. The closure may be of copper, light alloy or a fluoro polymer while the other parts of the valve in contact with the liquid are of cupro-nickel. The collector 7 and bellows 10 are welded to the rod 25.
