Abstract
A shut-off valve that has a closure orifice, a closure member to open and close a gas passage through the shut-off valve, an electromagnetic actuator including a movable assembly attached to the closure member, the closure member, and an electromagnetic filed generator magnetically associated with the movable assembly. The shut-off valve also includes a manual actuator for acting on the movable assembly, the manual actuator comprising an open position in which it is decoupled from the movable assembly, the electromagnetic actuator thus being able to act on the closure member to cause its closure.
Claims44
A shut-off valve comprising:
- an inlet conduit and an outlet conduit,
- a closure orifice disposed between the inlet conduit and the outlet conduit,
- a closure member movable between an open position and a closed position, in the open position the closure member is positioned away from the closure orifice to permit fluid communication between the inlet and outlet conduits, in the closed position the closure member interfaces with the closure orifice to prevent fluid communication between the inlet and outlet conduits,
- an electromagnetic actuator assembly comprising an electromagnetic field generator and a movable assembly to which the closure member is attached, the movable assembly being magnetically associated with the electromagnetic field generator and movable between first and second positions that respectively correspond to the closed and open positions of the closure member, and
- a manual actuator capable of being coupled to and subsequently decoupled from the movable assembly, the manual actuator movable between a closed position and an open position, in the open position the manual actuator is decoupled from the movable assembly, in the closed position the manual actuator is coupled with the movable assembly,
- wherein when the manual actuator is in the open position the movable assembly is configured to be moved between the first and second positions upon the electromagnetic field generator producing an electromagnetic field.

A system comprising:
- a shut-off valve comprising:
- a closure member movable between an open position and a closed position,
- an electromagnetic actuator assembly comprising an electromagnetic field generator and a movable assembly to which the closure member is attached, the movable assembly being magnetically associated with the electromagnetic field generator and movable between first and second positions that respectively correspond to the closed and open positions of the closure member, and
- a manual actuator capable of being coupled to and subsequently decoupled from the movable assembly, the manual actuator movable between a closed position and an open position, in the open position the manual actuator is decoupled from the movable assembly, in the closed position the manual actuator is coupled with the movable assembly,
- wherein when the manual actuator is in the open position the movable assembly is configured to be moved from the second position to the first position upon the electromagnetic field generator receiving an electrical pulse to produce an electromagnetic field;
- a sensor that is configured to produce a wired or wireless signal;
- and
- a controller electrically coupled to an electrical power source, the controller configured to receive the wired or wireless signal from the sensor and in response to the wired or wireless signal to generate and send the electric pulse to the electromagnet field generator of the shut-off valve.
