Abstract
A fluid discharge control assembly includes a cap member attachable to a conduit and a closure member positioned external to the conduit and outside an internal flow path. The closure member opens in response to fluid discharge and closes under gravity to restrict reverse flow and external intrusion.
Claims36
A fluid discharge control assembly comprising:
- a conduit having an outlet end;
- a cap member coupled to the outlet end;
- and
- a closure member movably supported by the cap member and positioned entirely external to the conduit and outside an internal flow path of the conduit;
- wherein the closure member is movable relative to the cap member between:
- (i) an open position permitting fluid discharge from the conduit;
- and
- (ii) a closed position covering the outlet end;
- wherein the closure member is configured to move to the open position in response to fluid exiting the conduit and to return to the closed position under gravitational force;
- and
- wherein the closure member includes a sealing edge configured to engage a seating surface formed on the cap member in the closed position to restrict reverse flow and external intrusion.

A condensate drain assembly comprising:
- a drain conduit having an outlet end;
- an end cap attached to the outlet end;
- and a closure member configured as a flapper and pivotally mounted to the end cap, wherein the closure member is positioned entirely external to the conduit and is configured to open in response to condensate discharge and close under gravity to cover the outlet end.
A method of controlling discharge from a conduit comprising:
- attaching a cap member externally to an outlet of the conduit;
- allowing fluid to exit the conduit and move a closure member to an open position;
- and
- allowing the closure member to return to a closed position solely under gravity to cover the outlet.
