    Abstract: A stress reactive valve includes a valve body disposed in a subsea safety system or other elongated components of hydrocarbon production systems. The valve body includes a frangible or breakable material such that when the subsea safety system or other elongated system undergoes a stress, such as a bending stress, the frangible valve body can react to the stress by breaking and thereby establishing fluid communication or a fluid path across the valve body. In a first or unbroken condition of the valve body, the valve body prevents fluid communication between a fluid inlet and a fluid outlet. In a second or broken condition of the valve body, fluid communication is allowed between the fluid inlet and outlet. The fluid communication can be used to actuate a device, or the fluid pressure can be used as pilot pressure to actuate a pilot operated valve system.

    Abstract: A valve mechanism is herein described that utilizes a frangible plug. The valve mechanism comprises a valve body having an inlet port and an outlet port and a passageway extending therebetween. The valve mechanism comprises a frangible plug that is held within the valve body to block the passageway when the plug is intact. The plug comprises a predefined fracture plane and is configured to fracture across the predefined fracture plane upon application of an impact force.

    Abstract: The present invention is directed to pressure relief devices and to corresponding pressure relief assemblies that have improved vacuum resistance, improved fragmentation resistance, and/or improved burst control while maintaining low mass. The pressure relief device includes a substantially flat flange section and a domed section. The domed section may include a transitional line that defines a change in the shape of the domed section. The pressure relief device may also include a bracket for securing or aligning a domed section to a flange section. The pressure relief device may further include a stress distribution feature that is disposed transversely to a line of weakness in the domed section. The pressure relief assembly may include a fastener having a wire that is configured to break and release the pressure relief device when subject to a predetermined tensile load.

    Abstract: A plug counter includes a seat receptive of a plug in a first position and capable of passing the plug in a second position. A first sleeve is in operable communication with the seat and is longitudinally movable in response to movement of the seat between the first position and the second position. A second sleeve is in operable communication with at least one of the first sleeve and the seat and is configured to index upon passage of the plug. A key is in operable communication with the seat and is configured to prevent movement of the seat to the second position after a selected number of plugs have passed the seat. A third sleeve is in operable communication with the first sleeve, and a release member is in operable communication with the third sleeve and is configured to move the third sleeve after it is released.

    Abstract: A nuclear engineering plant has a containment, whose interior chamber is subdivided by a wall into a systems chamber and an operating chamber which is accessible during normal operation. The containment ensures a particularly high operational reliability, in particular also in incident situations, in which hydrogen is released in the systems chamber. For this purpose, a number of overflow openings are provided in the partition wall, the respective overflow opening is closed by a closure element of a closure apparatus which opens automatically when a trigger condition associated with the respective overflow opening is reached. Closure apparatuses are provided which open both as a function of pressure and independently of pressure. The closure apparatus furthermore has a closure element containing a bursting film or a bursting diaphragm. The closure apparatus is configured such that it frees the overflow opening automatically when a predetermined environment-side trigger temperature is reached.
