Abstract
A wireless flow control device includes a shiftable apparatus and a power source configured to provide power to shift the shiftable apparatus from a first position to a second position. The wireless flow control device also includes a valve that forms a first fluid flow path through the wireless flow control device while the shiftable apparatus is in the first position. The wireless flow control device further includes an actuation assembly, which, when actuated, forms a second fluid flow path through the wireless flow control device, and a turbine configured to recharge the power source.
Claims18
A wireless flow control device, comprising:
- a shiftable apparatus;
- a power source configured to provide power to shift the shiftable apparatus from a first position to a second position, and from a second position to a third position;
- a valve that forms a first fluid flow path through the wireless flow control device while the shiftable apparatus is in the first position;
- an actuation assembly, which, when actuated, forms a second fluid flow path through the wireless flow control device;
- a second actuation assembly, which is actuated after the shiftable apparatus shifts from the second position to the third position, and which, when actuated, forms a third fluid flow path through the wireless flow control device;
- and
- a turbine configured to recharge the power source.
A wireless flow control device, comprising:
- a shiftable apparatus;
- a power source configured to provide power to shift the shiftable apparatus from a first position to a second position, and from a second position to a third position;
- a valve that forms a first fluid flow path through the wireless flow control device while the shiftable apparatus is in the first position;
- an actuation assembly, which is actuated after the shiftable apparatus shifts from the second position to the third position, and which, when actuated, forms a second fluid flow path through the wireless flow control device;
- a second actuation assembly, which, when actuated, forms a third fluid flow path through the wireless flow control device;
- and
- an actuator configured to actuate after the shiftable apparatus is shifted from the first position to the second position,
- wherein, actuation of the actuation assembly causes the shiftable apparatus to shift from the second position to the first position.
A method to reestablish fluid flow through a wireless flow control device, comprising:
- shifting a shiftable apparatus from a first position to a second position to sever a first fluid flow path through the wireless flow control device;
- after the first fluid flow path through the flow control device is severed, actuating an actuation assembly to rotate a turbine;
- providing power generated by the turbine to recharge a power source;
- after the power source is recharged, shifting the shiftable apparatus from the second position to the first position to reestablish the first fluid flow path;
- actuating the actuation assembly to establish a second fluid flow path through the wireless flow control device;
- shifting the shiftable apparatus from the second position to a third position to sever the second fluid flow path;
- and
- after fluid flow through the second fluid flow control device is severed, actuating a second actuation assembly to rotate the turbine.
