Breakaway valve for a cryogenic fluid tank

A breakaway valve for use with a first jacketed hose connected to a cryogenic tank and a second jacketed hose connected to a nozzle for dispensing cryogenic fluid, comprising:

• a tank-side valve configured to be connected to the first jacketed hose, the tank-side valve comprising a tank-side valve body, a first outer jacket, and a first jacket support, wherein the tank-side valve body defines tank-side pin holes, wherein the tank-side valve body, the first outer jacket, the first jacket support, and the first jacketed hose are configured to form a first vacuum-insulation layer when the tank-side valve is connected to the first jacketed hose, wherein the first jacket support includes:
• first bellows configured to reduce heat transfer with the first vacuum-insulation layer;
• and
• one or more first bellow supports that include first teeth configured to be inserted between and engage the first bellows to provide structural support to the first bellows;
• a nozzle-side valve configured to be connected to the second jacketed hose, the nozzle-side valve comprising a nozzle-side valve body, a second outer jacket, and a second jacket support, wherein the nozzle-side valve body defines nozzle-side pin holes, wherein the nozzle-side valve body, the second outer jacket, the second jacket support, and the second jacketed hose are configured to form a second vacuum-insulation layer when the tank-side valve is connected to the second jacketed hose;
• and
• a plurality of pins configured to extend through the tank-side pin holes and the nozzle-side pin holes to securely couple the tank-side valve and the nozzle-side valve together;
• 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 from the first jacketed hose and the second jacketed hose.
