Passive control shuttle-type check valve - a new nuclear-class fluid control component

摘要

A novel check valve - passive control shuttle-type check valve is introduced in this paper based on the comparison of the existing swing check valves including the liquid, structural principle, flow resistance coefficient, airproof and start-stop performances. The experimental and simulation analysis validated that shuttle-type check valve has the advantages of symmetric structure along the pipeline axis, balance circle flow, low coefficient streamline, adjustable start-stop time, multi-airproof, zero leakage and less noise.
