摘要： The present disclosure describes one or more embodiments of a device for localized flow control. The device includes a plunger configured to slide along a longitudinal axis; a gate connecting to a proximal end of the plunger and configured to slide with the plunger; a spacer disposed along the longitudinal axis and on a same side with the gate relative to the plunger; a soft tube disposed in a gap between the spacer and a proximal end of the gate; and a plunger controller configured to slide the plunger between a closed position and an open position. In response to the plunger at the open position, the device is at an open state configured to allow a flow in the soft tube, and in response to the plunger at the closed position, the device is at a closed state configured to cut off the flow in the soft tube.

摘要： A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular manifolds allows for expansion or modification of the manifold assembly to control a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

摘要： The invention relates to a control system (10) of a fire-extinguishing installation, having at least one control line (11) for controlling a controlling procedure of the fire-extinguishing installation, wherein the control line (11) in a passive operation is unpressurized and the control line (11) in a control operation is impinged with a control pressure, and a safety device (12), fluidically connected to the control line (11), having a pressure equalization chamber (13) in which a holding element (3) and a movable closure element (2) are disposed.
It is proposed that the closure element (2) is disposed in the pressure equalization chamber (13) so as to be displaceable between a first terminal position and a second terminal position, and the holding element (3) is configured for exerting on the closure element (2) a restoring force in the direction of the first terminal position, wherein the restoring force on the closure element (2) in the second terminal position of the closure element (2) is higher than the weight force of the closure element (2), and in the first terminal position of the closure element (2) is lower than a pressure force that in the control operation acts as a function of the control pressure on the closure element (2).-

摘要： A valve drive includes a housing in which a valve actuator with a dielectric elastomer transducer is arranged. A first end of the valve actuator is coupled to an actuating part for actuating a valve element and a second end of the valve actuator is coupled to a holding part, which is mounted in the housing via an adjusting device for adjusting a mechanical pretension of the dielectric elastomer transducer. The adjusting device comprises a single adjusting screw.

摘要： An emergency shut-off device comprises an activation means configured to generate an activation force in response to detecting a seismic event, and a magnetic driver having a hollow guide tube with two magnets affixed at a selected position on opposite sides along a length of the guide tube with like poles facing each other and a drive piston movable inside the guide tube. The driver piston is coupled to a third magnet and has a first end for receiving an activation force to move the third magnet crossing a magnetic repulse shift line formed by the two magnets, and a second end for applying the drive force to an output system to effectuate a shut-off of a fluid line.
