Safety valve, well system, and method employing a temperature sensor
Abstract
A safety valve, a well system and a method. The safety valve, in one aspect, includes a tubular housing, a flow tube positioned within the tubular housing, a valve closure mechanism positioned within the tubular housing, the flow tube configured to move between a closed position and an open position and thereby move the valve closure mechanism between a closed state and an open state, an electromagnet coupled to one of the tubular housing or the flow tube, and one or more permanent magnets coupled to an other of the flow tube or the tubular housing. The safety valve according to this one aspect, may further include a temperature sensor thermally coupled to the electromagnet, the temperature sensor configured to sense for a change in a temperature of the electromagnet to determine a health of the safety valve.
