Abstract
In an embodiment, there is disclosed a flexible fluid conduit having a breakaway coupling at one or both ends and a safety system that includes a spring in compression which applies thrust (a pull) to flapper valves at both ends of the flexible fluid conduit through relatively stiff bendable spring rods which push the valves open as long as the flexible hose is intact. Upon a hose failure such as a drive away, a coupling separation, a hose separation, or a longitudinal tear, the spring looses its compression and the pull applied to the valves by the spring in compression changes to a pull which immediately pulls the valves to close.
Claims16
A safety system for a fluid conduit comprising:
- a flexible fluid conduit having first and second ends;
- first housing having a first end coupled to said first end of said flexible fluid conduit;
- second housing having a first end coupled to said second end of said flexible fluid conduit, a first valve located in said first housing;
- a second valve located in said second housing;
- a spring having first and second ends located in said flexible fluid conduit;
- a first spring rod having a first end coupled to said first end of said spring and a second end coupled to said first valve;
- and
- a second spring rod having a first end coupled to said second end of said spring and a second end coupled to said second valve;
- wherein said spring, when in compression, pushes on said first and second spring rods to urge said first and second valves to their open condition and, upon the occurrence of a failure in the flexible fluid hose, said spring pulls on said first and second valves to close said valves.
