Abstract
A multi-flapper check valve includes a housing with an opening surrounded by a ring-shaped rim, a plurality of flappers, and a hinge that connects an end of each flapper to the rim of the housing. When the multi-flapper check valve is in a closed position, a first edge of each flapper seals against a second edge of an adjacent flapper.
