Abstract
Provided is a spring assembly, a valve assembly and a well system. The spring assembly, in one aspect, includes two separate independent wave springs positioned proximate one another such that peaks of adjacent ones of the two separate independent wave springs point toward one another, and valleys of the two separate independent wave springs point away from one another. The spring assembly, according to this aspect, further includes one or more anti-rotation features rotationally coupling the two separate independent wave springs together.
Claims21
A spring assembly, comprising:
- two separate independent wave springs positioned proximate one another such that peaks of adjacent ones of the two separate independent wave springs point toward one another, and valleys of the two separate independent wave springs point away from one another;
- and
- one or more anti-rotation features rotationally coupling the two separate independent wave springs together.
A valve assembly, comprising:
- a valve;
- a latch mechanism configured to shift the valve between an open position and a close position;
- a spring assembly coupled with the latch mechanism, the spring assembly including:
- two separate independent wave springs positioned proximate one another such that peaks of adjacent ones of the two separate independent wave springs point toward one another, and valleys of the two separate independent wave springs point away from one another;
- and
- one or more anti-rotation features rotationally coupling the two separate independent wave springs together;
- an indexing mechanism engaged with the latch mechanism and in an unarmed mode, the indexing mechanism configured to disengage from the latch mechanism to shift the valve between the open position and the closed position when receiving at least one cycle of threshold pressure;
- and
- a remote-activated downhole system coupled with the indexing mechanism, the remote-activated downhole system configured to:
- receive an activation pressure signal;
- and
- in response to receiving the activation pressure signal, arm the indexing mechanism.
A well system, comprising:
- a wellbore extending through one or more subterranean formations;
- a valve assembly located in the wellbore, the valve assembly including;
- a valve;
- a latch mechanism configured to shift the valve between an open position and a close position;
- a spring assembly coupled with the latch mechanism, the spring assembly including:
- two separate independent wave springs positioned proximate one another such that peaks of adjacent ones of the two separate independent wave springs point toward one another, and valleys of the two separate independent wave springs point away from one another;
- and
- one or more anti-rotation features rotationally coupling the two separate independent wave springs together;
- an indexing mechanism engaged with the latch mechanism and in an unarmed mode, the indexing mechanism configured to disengage from the latch mechanism to shift the valve between the open position and the closed position when receiving at least one cycle of threshold pressure;
- and
- a remote-activated downhole system coupled with the indexing mechanism, the remote-activated downhole system configured to:
- receive an activation pressure signal;
- and
- in response to receiving the activation pressure signal, arm the indexing mechanism.
