摘要： An arrangement for blocking/unblocking a fluid flow comprises: a component delimiting a fluid passage to conduct a fluid from a high pressure side to a low pressure side; a bursting disk at least indirectly attached to the component and separating the high and low pressure sides to close the fluid passage; a support element on the low pressure side, which supports the bursting disk to withstand a fluid pressure on the high pressure side that exceeds a nominal bursting pressure of the bursting disk but that is lower than a maximum pressure; and a controllable actuator actuatable for unblocking the fluid passage. To unblock the fluid passage, the actuator is arranged to destroy or damage the support element such that a fluid pressure on the high pressure side of the bursting disk exceeding the nominal bursting pressure causes the bursting disk to burst.

摘要： A burst disc system can include a plurality of burst discs serially arranged to successively rupture one at a time. Each burst disc can be configured to rupture at one or more set burst pressures. The system can include an indicator configured to allow a user to receive an indication that a last burst disc of the plurality of burst discs has ruptured.

摘要： A valve arrangement for inflating an inflatable device includes a valve body comprising an inlet, an outlet, a main fluid channel, a first ball detent, and a second ball detent. A lifter and a sleeve are located in the main fluid channel. A locking ball is disposed at least partially within a locking ball aperture disposed in the sleeve. A piston is coupled to the lifter and fluidly coupled to a command pressure cavity of the valve body. A spring biases the lifter toward a ball locking position whereby the lifter urges the locking ball at least partially into the first ball detent. A valve operation initiator controls a flow of pressurized gas into the command pressure cavity to urge the lifter to a ball releasing position to free the sleeve, as to the locking ball, to translate to an open position to fluidly couple the inlet with the outlet.

摘要： The present disclosure relates to a thermal pressure relief device for gas pressure tanks and/or gas pressure tank systems, comprising: a valve unit which can be fluidically connected to the gas pressure tank and/or the gas pressure tank system and comprises at least one fluid path, by means of which the gas pressure tank and/or the gas pressure tank system can be drained, in particular a gas stored under high pressure in the gas pressure tank and/or the gas pressure tank system can be discharged into an environment, wherein the valve unit comprises a locking element which can be shifted and/or moved between an open position, in which the gas can flow through the fluid path, and a closed position, in which no gas can flow through the fluid path, and a first trigger means configured to shift and/or move, due to heat impact, in particular when reaching a predetermined temperature, the locking element into the open position and/or to enable the locking element to shift and/or move into the open position, wherein the first trigger means is further configured to detect the heat impact at least at one further location of the gas pressure tank and/or the gas pressure tank system, which is not the installation location of the thermal pressure relief device, and/or to detect the heat impact at least at two spatially separated locations and/or areas, in particular of the gas pressure tank and/or the gas pressure tank system.

摘要： A fluid flow control valve includes a valve body having a bore configured to convey fluid from an inlet port to an outlet port. The inlet and outlet ports, and the bore therebetween, define a fluid flow path through the valve body. A gate element is disposed in the bore. The gate element is positionable in the bore from a first position, which allows fluid flow through the bore, to a second position which restricts fluid flow through the bore. An actuator is coupled to the gate element and is configured to urge the gate element from the first position toward the second position. A fuse consisting of a transformable retainer is configured to retain the gate element in the first position, while the retainer is in a first condition, and to allow the gate element to move toward the second position when the retainer transforms to a second condition. The transformable retainer may be configured to transform from the first condition to the second condition responsive to a signal, e.g., a signal indicative of a thermal change or a fluid leak. The innovative valves are especially but not exclusively suited for governing flow in a heat transfer system, particularly a heat transfer system for dissipating heat from a plurality of computer servers. The innovative valves may be embodied in systems, methods, apparatuses, and components.

摘要： A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.

摘要： An industrial gas spring with a pressure chamber in a casing with an end wall, a piston rod received at least in part in the casing for reciprocation between extended and retracted positions and a pressure relief assembly carried by the end wall. The pressure relief assembly may have a membrane communicating with the pressure chamber and a plunger configured to breach the membrane when engaged and moved by the piston rod when it overtravels its design intended retracted position.
