Definitions

  • a production choke valve may be used to throttle pressure and control the rate of production of petroleum fluids from a well.
  • Production chokes may also be used to control and throttle the flow of fluids being injected into a well, such as is done in enhanced oil recovery operations.
  • the keys 24 are positioned in pockets or slots (not shown) defined in the valve stem 18.
  • the keys 24 are positioned in through slots (not shown) in the anti -rotation mechanism 20.
  • the valve 10 also comprises a drive train 26 that is operatively coupled to a handle 28 by a key 30. Portions of the drive train 26 and the anti-rotation mechanism 20 are positioned within an actuator housing 27 that is coupled to the valve bonnet 12. A plurality of bearings 29 permit the drive train 26 to rotate within the actuator housing 27.
  • At least a portion of the drive train 26 comprises internally threaded sections (not shown), sometimes in the form of a threaded nut that is prevented from rotating within the drive train 26, that is adapted to engage external threads (not shown) formed on the portion of the valve stem 18 that is engaged with the drive train 26.
  • such a choke valve may be used to regulate the pressure seen by various components positioned downstream of the choke valve 10.
  • the position of the valve element 18 ultimately determines how much pressure drop the fluid experiences as the fluid flows through the valve 10. If the position indicator 32 does not accurately reflect the position of the valve element 16, then the downstream pressure of the fluid may be less than or greater than anticipated by the design process, which could lead to operational problems. Additionally, the flow rate of the fluid flowing through the choke valve 10 is also based upon the position of the valve element 16 relative to the valve seat.
  • the present application is generally directed to a unique torque operator for valves with a rising valve stem.
  • the valve includes a valve stem that is adapted for longitudinal movement along a first axis and a housing that is operatively coupled to the valve.
  • the valve also includes a torque operator that comprises a drive train and a linkage assembly that is operatively coupled to the valve stem and the housing.
  • the drive train comprises a threaded drive rod that is operatively coupled to the linkage assembly.
  • the axis of rotation of the threaded drive rod is positioned transverse to the first axis. Rotation of the threaded drive rod causes movement of at least one component of the torque operator and the valve stem in a direction corresponding to the first axis.
  • the method also includes determining a fluid flow characteristic of the valve by observing a position of the at least one component of the torque operator relative to a position indicator that correlates movement of the at least one component of the torque operator in a direction corresponding to the first axis with the fluid flow characteristic of the valve.

Abstract

L'invention concerne une vanne (100), qui comprend une tige de vanne (112) apte à un déplacement longitudinal le long d'un premier axe (113), un boîtier (114) qui est couplé de manière fonctionnelle à la vanne (100) et à un opérateur de couple (102) qui comprend un ensemble de liaison (107) qui est couplé de manière fonctionnelle à la tige de vanne (112) et au boîtier (114), et un train d'entraînement (105) qui comprend une tige d'entraînement filetée (130) qui est couplée de manière fonctionnelle à l'ensemble de liaison (107). L'axe de rotation (131) de la tige d'entraînement (130) est positionné transversalement par rapport au premier axe (113). La rotation de la tige d'entraînement (130) provoque le déplacement d'au moins un composant de l'opérateur de couple (102) et de la tige de vanne (112) dans une direction correspondant au premier axe (113). La vanne comprend également un indicateur de position (118) qui met en corrélation le déplacement du ou des composants de l'opérateur de couple (102) avec une caractéristique d'écoulement de fluide de la vanne (100).
