Safety system for fluid conduit

A safety system for a fluid conduit comprising:

• a flexible hose having first and second ends;
• a first housing containing a valve seat disposed at said first end of said hose and a second housing containing a second valve seat disposed at said second end of said hose, said first and second valve seats positioned a first predetermined distance from each other;
• a first pair of generally wedge shaped valve bodies disposed within said first housing at said first end of said hose and a second pair of generally wedge shaped valve bodies disposed within said second housing at said second end of said hose, said first and second valve seats disposed between said first and second pair of generally wedge shaped valve bodies, said first and second pairs of generally wedge shaped valve bodies positioned a second predetermined distance from said first and second valve seats, respectively;
• a first link connected to said first pair of generally wedge shaped valve bodies and a second link connected to said second pair of generally wedge shaped valve bodies;
• a first connecting linkage connected to said first linking cable and a second connecting linkage connected to said second linking cable;
• and
• a cable having first and second cable ends, positioned within said hose, said first cable end connected to said first connecting linkage and said second cable end connected to said second linkage, said cable retaining said first and second pairs of generally wedge shaped valve bodies said second predetermined distance from said first and second valve seats, respectively, during an open flow condition, and seating one or more of said first and second pairs of said generally wedge shaped valve bodies with said first and second valve seats, respectively, during a hose failure.

A safety system for a fluid conduit comprising:

• first and second housings;
• a first flexible fluid conduit having first and second ends attached to said first and second housings, respectively;
• a second outer flexible fluid conduit having first and second ends attached to said first and second housings, respectively, said second outer flexible fluid conduit surrounding said first flexible fluid conduit;
• a cavity defined by and between said first and second flexible fluid conduits;
• an indicator material located inside of said cavity to indicate a fault condition of said first or second flexible fluid conduits;
• and
• fluid flow cut off means for stopping fluid flow upon failure of said first flexible fluid conduit.

A safety system for a fluid conduit comprising:

• a flexible fluid conduit having first and second ends;
• a first valve seat disposed at said first end of said conduit and a second valve seat disposed at said second end of said conduit, said first and second valve seats positioned a first predetermined distance from each other;
• a first plurality of valve bodies disposed at said first end of said conduit and a second plurality of valve bodies disposed at said second end of said conduit, said first and second valve seats disposed between said first and second plurality of valve bodies, said first and second plurality of valve bodies positioned a second predetermined distance from said first and second valve seats, respectively;
• valve control means for
• retaining said first and second plurality of valve bodies said second predetermined distance from said first and second valve seats, respectively, during an open flow condition, and
• seating one or more of said first and second plurality of valve bodies with said first and second valve seats, respectively, during a conduit failure;
• and
• first and second springs biasing said first and second plurality of valve bodies, respectively against said valve control means.
