Abstract:
An example breakaway valve for a cryogenic fluid tank includes a first valve and a second valve. The first valve includes a first valve body that defines through-holes and notches along a distal edge. The second valve includes a second valve body that defines a first set of blind holes and a second set of blind holes. Shear pins are configured to extend through the through-holes and into the first set of blind holes. The shear pins are configured to shear apart when at least a predetermined axial force is applied. Anti-rotation pins are configured to extend through the notches and into the second set of blind holes. The anti-rotation pins are configured to withstand up to at least a predetermined torsional force to deter the second valve from separating from the first valve prior to at least the predetermined axial force is applied.
