Cryogenic Disconnect · 模型 43120
My name is Juan Martin Del Piano, I am a mechanical engineering student at the Faculty of Exact Sciences, Engineering and Surveying (FCEIA) of the National University of Rosario, Santa Fe, Argentina (UNR): FCEIA-UNR. Web: https://web.fceia.unr.edu.ar/es/ This work is based on the NASA challenge: https://grabcad.com/challenges/low-leakage-cryogenic-disconnects-for-fuel-transfer-and-long-term-storage My coupling concept is simple, it is a conical seat, where the male coupling has a rod inside. When both couplings make contact, the movement of the stem is actuated and consequently actuates the valve on the female coupling side. When it reaches its final stroke, the stem is aligned over the female side orifices and this allows the fuel to flow through it. The mechanism also has two outer rings that serve to align and center the connection. For the realization I have immersed myself in the analysis through the concept of PCDC (divergent convergent creative post-processing), which through this study I could associate and enrich my design with the concepts of: “https://grabcad.com/library/venturi-effect-1” - https://grabcad.com/marcelo.valderrey-1. “https://grabcad.com/library/sub-zero-cryo-sis-concept-1” - https://grabcad.com/melville-1 “https://grabcad.com/library/the-optimized-l-f-d-1” - https://grabcad.com/donald.jacob-1
