    摘要: The present invention provides a water-excluding valve assembly for a diving snorkel which can easily be attached to an existing, simple, low cost snorkel giving it features of a more expensive snorkel. This water-excluding valve assembly for a diving snorkel uses a single ball float mechanism to seal off the snorkel airway in the event that the upper end of the snorkel airway tube goes below the water line.
