  • Actuator 10 is used to open or close valve 20, to which quick connectable actuator 10 is connected.
  • Valve 20 can be, for example, associated with a wellhead assembly that is disposed over a well (not shown).
  • the wellhead assembly can include a wellhead housing, a production tree over the housing, and flow lines connected to the tree or the wellhead assembly.
  • the flow lines and wellhead assembly can include embodiments of valve 20 described herein.

  • valve 20 can be a gate valve or any other type of valve that is actuated by the extension of a linear member.
  • bonnet 22 is connected to the body of valve 20.
  • Bonnet 22 and valve 20 prevent the flow of fluid from valve 20 to actuator 10. In other words, there is an absence of fluid communication between valve 20 and actuator 10.
  • actuator housing 12 can be removed from bonnet 22 while fluid is present in valve 20 and no fluid will flow out of valve 20 through bonnet 22 or otherwise.
  • Valve stem 24 passes through bonnet 22 and has a stem axis 23.
  • Valve stem 24 has a first portion with valve stem nub 25 and with a second portion operable to be connected to a valve member, such as a gate, of valve 20.
  • Valve stem 24 moves axially between an extended position ( Figure 2) and a retracted position ( Figure 3) to actuate valve 20 and move the valve member between the open and closed position.
  • Actuator 10 is used to actuate valve 20 by moving the valve stem 24 axially. Actuator 10, valve 20, bonnet 22, and each of their respective components make up the valve assembly.
  • housing lugs 26 protrude radially inward from inner diameter surface 28 of actuator housing 12. Housing lugs 26 are spaced apart around a circumference of inner diameter surface 28 to define housing slots 30 therebetween.
  • Bonnet 22 has lower flange 32 extending radially outward.
  • Lower flange 32 can be used to connect bonnet 22 to the body of valve 20.
  • locking flange 34 extends radially from bonnet 22 and includes top surface 36.
  • the outer diameter of locking flange 34 is less than or about equal to the inner diameter surface 28 of actuator housing 12 such that inner diameter surface 28 of actuator housing 12 can fit over locking flange 34.
  • a plurality of bonnet lugs 38 are spaced apart around a circumference of bonnet 22.
  • Bonnet lugs 38 protrude radially inward from bonnet 22 to define a plurality of bonnet slots 40 therebetween.
  • Each of the housing lugs 26 are sized to pass axially through a respective one of the bonnet slots 40 when actuator housing 12 is in a released position. That is, the circumferential arc length of each bonnet slot 40 is at least equal to or greater than the circumferential arc length of housing lugs 26.
  • Bonnet lugs 38 are spaced axially apart from locking flange 34 so that groove 42 ( Figure 6) is defined between a bottom surface of bonnet lugs 38 and top surface 36 of locking flange 34.
  • Groove 42 is an annular groove. The axial height of groove 42 is greater than or about equal to the axial height of housing lugs 26, measured along actuator axis 14.
  • housing lugs 26, thus, are able to pass axially through bonnet slots 40. After passing through bonnet slots 40, housing lugs 26 are positioned in groove 42 below bonnet lugs 38. In the released position, housing lugs 26 are not axially aligned with bonnet lugs 38 but instead housing lugs 26 remain axially aligned with bonnet slots 40. Housing lugs 26 contact or rest upon top surface 36 of locking flange 34, thus preventing further downward movement of actuator housing 12 relative to bonnet 22. Because housing lugs 26 are axially below bonnet lugs 38, actuator housing 12 can rotate relative to bonnet 22.
  • actuator housing 12 When actuator housing 12 rotates, relative to bonnet 22, to a position wherein at least a portion of bonnet lugs 38 are axially above housing lugs 26, such that bonnet lugs 38 prevent axial movement of actuator housing 12 in at least one direction, actuator housing 12 is in a locked position. In the locked position, bonnet lugs 38 prevent upward axial movement of housing lugs 26.
  • actuator housing 12 In certain embodiments, less than one revolution of actuator housing 12 is required to move actuator housing 12 from the released to the locked position. In embodiments, actuator housing 12 can move as little as 1/2, 1/3, 1/4, 1/6, 1/8, 1/10, or 1/16, of a revolution, depending on the size and number of lugs, to move from the released to the locked position. As one of skill in the art will appreciate, no fluid from valve 20 is in the vicinity of bonnet lugs 38 and housing lugs 26 and, thus, there can be an absence of seals between the lower end of actuator housing 12 and the upper end of bonnet 22.
  • securing mechanism 44 can prevent rotation of actuator housing 12, relative to bonnet 22, when actuator housing 12 is in the locked position.
  • securing mechanism 44 is a latch assembly with rotational lock that includes latch body 46 having one or more latch tabs 48 protruding inward therefrom when latch body is positioned in latch aperture 50.
  • Latch aperture 50 is an opening through the sidewall of actuator housing 12. In embodiments, no seals are required at aperture 50 because there is an absence of pressurized fluid in actuator housing 12 proximate to aperture 50.
  • Latch body 46 is pivotally connected to actuator housing 12 by pin 52, which passes through a lateral bore, or cross-drilled hole, of actuator housing 12. Latch body 46 pivots on pin 52 between an unlatched position and a latched position.
  • Detent 53 is a spring loaded plunger that protrudes from one or both sides of latch body 46. Detent 53 can move between an extended position when a greater amount of detent 53 protrudes from latch body 46 and a retracted position where a lesser amount of detent 53 protrudes from latch body 46. Detent 53 extends from latch body 46 and can engage lateral bore 54 of actuator housing 12 to selectively prevent latch body 46 from pivoting relative to actuator housing 12 when detent 53 is in the extended position. When detent 53 is in the retracted position, latch body 46 can pivot relative to actuator housing 12 to allow for relative rotational movement between bonnet 22 and actuator housing 12.
  • Latch tab 48 also includes tab sidewalls 56. Latch tab 48 is positioned in actuator housing 12 slightly above housing lugs 26, such that at least a portion of latch tab 48 is in the same axial location as bonnet lugs 38 when actuator housing 12 is landed on bonnet 22. In the latched position, latch tab sidewalls 56 engage the sidewalls 58 of bonnet lugs 38, thus preventing further rotation of actuator housing 12 in either direction relative to bonnet 22.
  • the outer surface of latch tab 48 can be contoured with a radius that generally matches the outer diameter profile of actuator housing 12.
  • latch tab 48 contacts a top edge of bonnet lug 38 when actuator housing 12 is placed on bonnet 22.
  • Latch tab 48 can be deflected outward as actuator housing 12 is moved further onto bonnet 22.
  • the shape of taper 59 can facilitate such deflection.
  • latch tab 48 pivots to a position where detent 53 is aligned with lateral bore 54, a portion of detent 53 is urged by an internal spring (not shown) into lateral bore 54.
  • detent 53 engages lateral bore 54 to hold latch tab 48 in the latched position and thus prevent latch tab 48 from moving to the unlatched position.
  • latch tab sidewalls 56 engage the sidewalls 58 of bonnet lugs 38, preventing further rotation of actuator housing 12 in either direction relative to bonnet 22.
  • securing mechanism 44 can have alternate forms, such as those shown in U.S. Application No. 14/949,324.
  • cylinder assembly 60 is located within actuator housing 12.
  • Cylinder assembly 60 includes inner cylinder 62 and outer cylinder 64.
  • Inner cylinder 62 is static relative to the actuator housing 12.
  • Inner cylinder 62 can be fixed or releasably secured to outer end of actuator housing 12.
  • inner cylinder 62 is secured to actuator housing 12 by way of cap 19.
  • Inner cylinder 62 can be a generally tubular shaped member with a central bore centered around actuator axis 14. An end of inner cylinder 62 proximate to cap 19 can be closed and an opposite end of inner cylinder 62 can be open.
  • Outer cylinder 64 has an open end for receiving inner cylinder 62 and a closed opposite end. Outer cylinder 64 is axially moveable relative to actuator housing 12. Outer cylinder 64 circumscribes at least a portion of inner cylinder 62 and an outer diameter of inner cylinder 62 dynamically seals with an inner diameter of outer cylinder 64. Inner cylinder 62 can reciprocate in and out of a bore of outer cylinder 64 as outer cylinder 64 moves axially within actuator housing 12.
  • outer cylinder 64 and the inner bore of inner cylinder 62 together define a sealed piston chamber 66 within the interior of cylinder assembly 60.
  • inner cylinder 62 and outer cylinder 64 can act as a piston assembly and outer cylinder 64 can move axially relative to inner cylinder 62 by changing the pressure of a pressure media within piston chamber 66.
  • Injection port 68 provides a fluid flow path for injecting the pressure media from an exterior of actuator housing 12 to piston chamber 66 of the interior of cylinder assembly 60.
  • Outer cylinder 64 moves axially within actuator housing 12 by a change of pressure within piston chamber 66 of cylinder assembly 60.
  • Biasing member 70 is located within actuator housing 12. Biasing member 70 has a first end that engages biasing retainer 72 of outer cylinder 64 and a second end that engages actuator housing 12. Biasing member 70 urges outer cylinder 64 in a direction towards outer end 18 of actuator housing 12 and away from housing lugs 26.
  • biasing member 70 is a spring. In order to move outer cylinder 64 axially within actuator housing 12, the pressure media injected into piston chamber 66 acts on the closed end of outer cylinder 64 to cause outer cylinder 64 to overcome the spring force and move outer cylinder 64 towards valve end 16 of actuator housing 12 and towards housing lugs 26.
  • biasing member 70 will move outer cylinder 64 back towards outer end 18 of actuator housing 12 and away from housing lugs 26.
