EMERGENCY SHUTOFF VALVE FOR USE IN A FUEL DISPENSING SYSTEM |
摘要 |
<p>An emergency shutoff valve is provided that includes a housing defining a fluid inlet, a fluid outlet and a fluid flow passage extending therebetween. The valve includes a valve element disposed within the housing and releasabl y latched in an open position by a latching mechanism. An expansible member defines at least a portion of a sealed expansible chamber that is sealed at locations downstream and upstream of a weakened portion of the housing. The emergency shutoff valve defines a failure mode wherein the structural integrity of the housing is compromised to an extent wherein fuel can flow into the expansible chamber when a predetermined load is applied to a portion of the housing, wherein the expansible member is operable for uncoupling the latching mechanism so that the valve element moves from the open position to the closed position.</p> |
