ABSTRACT:
A butterfly valve provided within a disconnect of a fluid flow line, such as in a fuel dispensing system, incorporating a pair of decoupling members, at least one or a pair of butterfly valves mounted within and in proximity with location for disconnection of the conduit, the butterfly valve incorporating a valve disk held by a retainer and which is spring biased for snapping into closure against its valve seat, when disconnection occurs, to prevent the further flow of fuel from the conduit, or in the instance where a pair of the butterfly valves of this design, are incorporated proximate each of the disconnect members, upon severance of the conduit or hose at this location, effecting an immediate closure of both butterfly valves, preventing the discharge of any further fluid from the remaining separated parts of the fluid conduit. The specific construction of each butterfly valve incorporates a set of projections that normally mount upon shoulders of the valve retainer, and upon release, and pivoting of the disk towards closure, the projections ride within formed grooves for guiding the valve disk into a fluidic seal against a conveniently disposed valve seat, and said projections further facilitating the reopening of the butterfly valve upon flow of the fluid in an opposite direction. A vapor recovery conduit arranged generally in proximity with, or concentrically around, the fluid flow line to provide for passage of fluid vapors therethrough during functioning of the fuel dispensing system.
