Abstract

The safety element is disposed at the end of a line which communicates with a pressure vessel. The safety element allows flow from the line into the pressure vessel. Upon an abrupt decrease in pressure in the line caused, for example, by a fracture, the safety element collapses so as to close off the line to the pressure vessel. The safety element is constructed as either a folded cone or as a rigid plate with plastically deformable members securing the plate to a line.
