Check valve with oversized bill |
摘要 |
A check valve having an upstream inlet part mountable on a discharge end of a conduit, a downstream outlet part adapted to prevent backflow of fluid through the check valve, and a transition part located between the upstream inlet part and the downstream outlet part. A longitudinal dimension of the downstream outlet part extending in a direction transverse to a direction of flow is at least approximately 1.57 times the diameter of the upstream inlet part.
