摘要： An emergency shutoff valve includes a fluid conduit having a frangible area defined therein, a valve member operatively coupled to said conduit upstream of the frangible area, an expansible chamber having the frangible area defined therein, a movable member defining at least a portion of the expansible chamber, and a linkage operatively coupled to the movable member and the valve member for shutting the valve upon movement of the movable member in response to leakage of fluid through the frangible area. A method of shutting off fuel includes defining an expansible chamber about a frangible area in the conduit, moving a member defining a portion of the expansible chamber in response to leaking fuel, and shutting off a fuel valve in response to moving the movable member.

摘要： 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 releasably 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.

摘要： An improved control valve for a holding tank is provided for cutting off the flow of fluid into a holding tank device in response to achieving a predetermined fluid level in the holding tank. The assembly includes a housing configured for placement adjacent a spill container. The housing has an upper inlet and a lower outlet and a flow passage therebetween having a diameter of which is substantially constant along its longitudinal length. A valve poppet is situated within the flow passage and is axially rotatable between a substantially vertical, open position, that allows for the flow of fluid through the flow passage, and a closed position substantially blocking fluid flow through the flow passage when the holding tank has reached a predetermined level of fluid.

摘要： A locking device has a locking plate mounted on a ball valve housing and a hasp slidably mounted on the locking plate for movement into a position in which the hasp can engage the ball valve handle to prevent movement thereof irrespective of whether the handle is in the ball valve open position or the ball valve closed position. When the hasp is disposed to engage the handle, an opening in the hasp is aligned with an opening in the locking plate to receive a padlock for locking the hasp in the handle engaging position so that the handle cannot be turned to move the ball valve.

摘要： A drop tube segment includes a conduit with a first end portion and a second end portion. The drop tube segment further comprises a valve assembly with a valve member associated with the first end portion, a float, and a linkage device pivotally connected with respect to the valve member. The linkage device is adapted for communication with the float such that the float may facilitate in adjusting the position of the valve member with respect to the first end portion of the conduit in response to a liquid level in a liquid reservoir. The drop tube segment further includes a fastening section located at the second end portion of the conduit for fluid tight fastening with an end portion of another drop tube segment. The fastening section comprises a sealing surface and a threaded portion adapted for threaded engagement with a threaded portion of another drop tube segment. The drop tube segment still further includes a sealing member that engages the sealing surface of the fastening section and is adapted to engage a sealing surface of another drop tube segment.

摘要： A fuel nozzle has a modular construction wherein valve, venturi and spout modules are mounted in a bore formed in a nozzle body. The main fuel valve is controlled, independently of fuel pressurization, in response to a mechanical signal input, acting through a servo valve. The mechanical signal input is provide by a finger displaced trigger, acting through a pivotal lever arm and latching means that form part of the automatic shut off means for preventing overfill of a fuel tank. The venturi module has a venturi passage for generating a vacuum employed in the automatic shut off mechanism. The venturi module includes a bypass passage that enables sufficient vacuum force to be generated at both high and low flow rates. The spout module comprise an extruded spout (including a venturi vent passage) and a pair of mechanical adapter shells that are mechanical locked onto the spout and mechanically locked to the nozzle body, to secure the several modules in assembled relation.
