摘要： A pressure relief device and a hydraulic fracturing system having a pressure relief device are provided. In one form, the pressure relief device has a valve body with a linearly extending throughbore between the inlet and outlet thereof. A rupture disc is secured in the valve body so that a frangible dome wall portion thereof has a reverse-acting orientation in the valve body bore. The hydraulic fracturing system includes a pump and a delivery line that receives pressurized fracturing fluid from the pump and delivers it to a well. A pressure relief device is installed along the delivery line. A sensor detects fluid flow downstream of the pressure relief device which allows the pump to be shut down when the downstream fluid flow is detected. The pressure relief device can have a body with a domed rupture disc and the sensor therein.

摘要： An over-pressure limiting arrangement for a cryogen vessel includes an access neck providing access into the cryogen vessel, a tubular structure extending through the access neck, a turret outer assembly joined leak-tight to the cryogen vessel and defining an interior volume that is separated from the atmosphere by a protective valve or burst disc, enclosing an upper extremity of the access neck and the tubular structure. An egress path defines a route for cryogen gas to escape from the turret outer assembly, and a pressure-responsive quench valve seals the egress path and opens when a differential pressure between the interior of the turret outer assembly and the interior of the egress path exceeds a predetermined value. An auxiliary burst disc, or a valve, is attached to the tubular structure within the turret outer assembly, with an inner surface thereof exposed to the interior of the tubular structure and an outer surface thereof exposed to the interior of the turret outer assembly.

摘要： An apparatus for rapidly terminating of the flow of any fluid or particulate material through a conduit responsive to predefined dangerous conditions. A particular application will terminate fuel flow through a large fuel supply conduit in a racing vehicle responsive to a fire or accident or other dangerous condition. The apparatus includes a gas supply source that is opened responsive to actuation of the apparatus such that gas passes into a cylinder which moves to force a liquid to hydraulically expand an inflatable member which is operative to expand within the flow conduit to instantaneously terminate material flow therethrough.

摘要： A rupture feature releases pressurized gas into a diffuser through an egress opening in an inflator wall responsive to a pressure impulse in the inflator. A sturdy rupture fragment is positioned opposite the egress opening. A thin rupture membrane continuously circumscribes and sealingly interconnects the rupture fragment to the inflator about the egress opening. Rupture membrane thickness is less than rupture fragment thickness or inflator wall thickness at the egress opening. The rupture membrane is upstanding from the inflator wall about the egress opening to a constant height. The rupture fragment and the rupture membrane are integrally-formed with each other and with the inflator wall at the egress opening. The pressure impulse impacts the rupture fragment, urges the rupture fragment away from the inflator, detaches the rupture fragment from the inflator by fully transversely fracturing the rupture membrane, and drives the rupture fragment into containment within the diffuser.
