The gas safety valve is a ball valve that is integral to the primary gas line that is in communication with the carbon monoxide detectors with an electrical signal line that transmits a low voltage electronic signal to the gas safety valve when carbon monoxide is detected..

Capillary hanger arrangement for deploying control line in existing wellhead
To deploy a capillary string through a wellhead to a downhole safety valve, a control port and a retention port are drilled in an adapter between a casing hanger and a gate valve or elsewhere. The capillary string is connected to a first port of a capillary hanger and installed through the wellhead.

Detection of blocked air line for electric compressor at start up
Systems and methods for detecting a blocked air discharge line of an air compressor are described, which include monitoring motor current (imtr) drawn by a compressor motor (14), and calculating a three-point moving average for a steady state current drawn by the compressor motor (14) upon the motor reaching steady state (nominal) operating speed. A current threshold (imtr_limit) (28) is calculated as a function of the three-point moving average, and a determination is made regarding whether a current drawn by the compressor motor (14) has exceeded the current threshold (28) and is consistent with a current profile (34) indicative of a blocked air line (15).

Robust electric screw compressor blocked air line detection via motor current monitoring
Systems and methods for detecting a blocked air discharge line of an air compressor are described, which include monitoring motor current (imtr) drawn by a compressor motor, and calculating a three-point moving average for a steady state current drawn by the compressor motor upon the motor reaching steady state (nominal) operating speed. After expiration of a predetermined time period t1 that commences upon the compressor motor reaching steady state speed, a determination is made regarding whether a difference between a current drawn by the compressor motor and the three-point moving average has exceeded a predetermined current value i2 and is consistent with a current profile indicative of a blocked air line.

Safety valve with electrical actuator and tubing pressure balancing
A well tool for use with a subterranean well can include a flow passage extending longitudinally through the well tool, an internal chamber containing a dielectric fluid, and a flow path which alternates direction, and which provides pressure communication between the internal chamber and the flow passage. A method of controlling operation of a well tool can include actuating an actuator positioned in an internal chamber of the well tool, a dielectric fluid being disposed in the chamber, and the chamber being pressure balanced with a flow passage extending longitudinally through the well tool, and varying the actuating, based on measurements made by at least one sensor of the well tool..
