초록

A marine riser safety valve is disclosed which, when placed in series with a deep water marine riser string, prevents collapse of riser pipe when inadvertent gas influx replaces the drilling fluid column. A cylindrical body is provided having a depression formed therein with at least one diaphragm port from the central bore of the body through the wall of the depression. A valve port is provided axially from the depression. A cylindrical member including a cylindrical diaphragm and a valve sleeve are joined end-to-end. The cylindrical member is disposed ...
