Breakaway valve for a cryogenic fluid tank

A breakaway valve for use between a cryogenic tank and a nozzle for dispensing cryogenic fluid, comprising:

• a tank-side valve configured to be fluidly connected to the cryogenic tank, the tank-side valve comprising a tank-side valve body that includes a distal edge, wherein the tank-side valve body defines one or more through holes and one or more notches along the distal edge;
• a nozzle-side valve configured to be fluidly connected to the nozzle, the nozzle-side valve comprising a nozzle-side valve body that defines one or more first blind holes and one or more second blind holes;
• one or more shear pins each configured to extend through a respective one of the one or more through holes and into a respective one of the one or more first blind holes, wherein the one or more shear pins are configured to shear apart when at least a predetermined axial force is applied to pull the nozzle-side valve away from the tank-side valve;
• and
• one or more anti-rotation pins each configured to extend through a respective one of the one or more notches and into a respective one of the one or more second blind holes, wherein the one or more anti-rotation pins are configured to withstand up to at least a predetermined torsional force to deter a torsional force from separating the nozzle-side valve from the tank-side valve, wherein each of the one or more anti-rotation pins has a thickness that is associated with the predetermined torsional force and is thicker than a narrowest portion of each of the one or more shear pins so that the one or more anti-rotation pins prevent the one or more shear pins from breaking when a torsional force less than the predetermined torsional force is applied;
• and
• wherein, when the tank-side valve and the nozzle-side valve are securely coupled together, the tank-side valve and the nozzle-side valve are in respective open positions to permit the cryogenic fluid to flow from the cryogenic tank and to the nozzle during a filling event;
• and
• wherein, when the tank-side valve and the nozzle-side valve are decoupled from each other in a breakaway event, the tank-side valve and the nozzle-side valve are in respective closed positions to prevent the cryogenic fluid from being emitted.
