Title:
BREAKAWAY VALVE FOR A CRYOGENIC FLUID TANK
Document Type and Number:
WIPO Patent Application WO/2023/087216
Kind Code:
A1
Abstract:
A breakaway valve for a cryogenic fluid tank is disclosed. An example breakaway valve includes a tank-side valve connected to a cryogenic tank and a nozzle-side valve connected to a nozzle. The tank-side valve includes a tank-side valve body that defines tank-side pin holes. The nozzle-side valve includes a nozzle-side valve body that defines nozzle-side pin holes. The breakaway valve includes pins configured to extend through the tank-side pin hole and the nozzle-side pin hole to securely couple the tank-side valve and the nozzle-side valve together. 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 cryogenic fluid from being emitted.
