Abstract
The present disclosure relates to a valve system that includes a valve having a spool moveable from an un-actuated position to an actuated position in response to actuation of the valve. The valve system also includes a wire to secure the valve in the un-actuated position, a first resistor electrically coupled with the wire and configured to release the wire to actuate the valve and move a first component coupled to the wire toward a second component, and a second resistor electrically coupled with the wire to detect connection of the first component with the second component.
Claims10
A valve system comprising:
- a valve comprising a spool moveable from an un-actuated position to an actuated position in response to actuation of the valve;
- a wire to secure the valve in the un-actuated position;
- a first resistor electrically coupled with the wire and configured to release the wire to actuate the valve and move a first component coupled to the wire toward a second component, wherein the first component comprises a pin disposed on a first end of the wire;
- a second resistor electrically coupled with the wire to detect connection of the first component with the second component;
- and
- a plurality of release washer segments, wherein the wire is disposed around the plurality of release washer segments to retain the plurality of release washer segments in a contracted state when the valve is in the un-actuated position, and wherein the second component comprises a spring element disposed in a socket frame of a housing of one of the plurality of release washer segments.
A valve system comprising:
- a valve comprising a spool slidable within a sleeve from an un-actuated position to an actuated position in response to actuation of the valve;
- a wire coupled to a plurality of release washer segments to retain the plurality of release washer segments in a contracted state that secures the spool within the sleeve in the un-actuated position;
- a first resistor electrically coupled with the wire and configured to release the wire to expand the plurality or release washer segments away from one another to move a first component coupled to the wire toward a second component and to allow the spool to slide within the sleeve to the actuated position, wherein the first component comprises a pin disposed on a first end of the wire and wherein the second component comprises a spring element disposed in a socket frame of a housing of one of the plurality of release washer segments;
- and
- a second resistor electrically coupled with the wire to detect connection of the first component with the second component.
A method comprising:
- releasing a wire to move a spool from an un-actuated position to an actuated position to actuate a valve;
- expanding a plurality of segments of a release washer away from one another in response to the movement of the spool;
- moving a first component coupled to the wire toward a second component in response to the expansion of the plurality of segments, wherein the first component comprises a pin disposed on a first end of the wire and wherein the second component comprises a spring element disposed in a socket frame of a housing of one of the plurality of release washer segments;
- and
- detecting a successful actuation of the valve based on a voltage change produced by the first component contacting the second component.
