<p>A safety system for a fluid conduit (10) comprising a flexible fluid conduit having first and second ends, a first valve seat disposed at the first end of the conduit and a second valve seat disposed at the second end of the conduit. The first and second valve seats are positioned a first predetermined distance from each other. A first plurality of valve bodies (28a, 26a) are disposed at the first end of the conduit and a second plurality of valve bodies (28b, 26b) are disposed at the second end of the conduit. The first and second valve seats are disposed between the first and second plurality of valve bodies, with the first and second plurality of valve bodies positioned a second predetermined distance from the first and second valve seats, respectively. A valve control means retains the first and second plurality of valve bodies the second predetermined distance from the first and second valve seats, respectively, during an open flow condition, and seats one or more of the first and second plurality of valve bodies with the first and second valve seats, respectively, during a conduit failure.</p> |
