  • the actuator shaft 68 When the actuator shaft 68 is in the extended position, as illustrated in FIG. 3, the inner portion 80 of the sealing member 72 can be flexed toward the valve body 22 such that lower surface 83 of the sealing member 72 contacts a mating surface 87 that is disposed between the fluid inlet 26 and the fluid outlet 28 in order to provide an effective seal therebetween that prevents fluid from flowing between the fluid inlet 26 and the fluid outlet 28.
  • the actuator shaft 68 When the actuator shaft 68 is in the retracted position, as illustrated in FIG. 4, the inner portion 80 of the sealing member 72 can be spaced from the valve body 22 to allow fluid to flow through the valve body 22 between the fluid inlet 26 and the fluid outlet 28 and past the sealing member 72.

  • the handle 70 can include a threaded collar 89 that is threadably engaged with the threaded stem 88 such that rotation of the handle 70 facilitates sliding of the actuator shaft 68 between the extended position (FIG. 3) and the retracted position (FIG. 4).
  • the actuator shaft 68 can be slid into the retracted position by rotating the handle 70 in an unthreading or loosening direction (e.g., in a counter-clockwise direction) and can be slid into the extended position by rotating the handle 70 in a threading or tightening direction (e.g., in a clockwise direction).
  • the handle 70 is shown to be operably coupled with the actuator shaft 68, any of a variety of suitable alternative actuators are contemplated that can be operably coupled with the proximal end 74 of the actuator shaft 68, to facilitate movement of the actuator shaft 68 between the extended and retracted positions, such as, for example, a pneumatic actuator or an electric actuator (e.g., a solenoid).

  • upper and lower surfaces 81, 83 can contact the bottom surface 58A of the side wall 58 and the valve body 22, respectively, at the outer portion 82 of the sealing member 72 such that the sealing member 72 is sandwiched (i.e., compressed) between the perimeter compressor 52 and the valve body 22.
  • the external collar 56 can be proximate enough to the base collar 40 to allow a clamp 90 to secure the external collar 56 and the base collar 40 together. The clamp 90 can prevent the compressor assembly 50 from being inadvertently slid into the retracted position.
  • the clamp 90 can facilitate sliding of the external collar 56 and the base collar 40 together such that the perimeter compressor 52 presses the outer portion 82 of the sealing member 72 and the valve body 22 together with enough force to effectively create a seal (i.e., a perimeter seal) therebetween.
  • the sealing member 72 can include an annular rib 91 (FIG. 5) that interfaces with an annular groove 92 (FIG. 5) on the valve body 22 in an interfacing fit to releasably secure the valve body 22 and the outer portion 82 of the sealing member 72 together. It is to be appreciated, that the valve body 22 and the sealing member 72 can additionally or alternatively include other features that interface with each other to ensure proper alignment and coupling therebetween.
  • the clamp 90 can include a pair of arms 93 (FIG. 2) and a wingnut 94 (FIG. 2) that interfaces with the arms 93 to adjust the clamping force imparted by the clamp 90.
  • a wingnut 94 FIG. 2
  • the wingnut 94 When the wingnut 94 is tightened, and the arms 93 of the clamp 90 can be drawn together which can cause chamfered shoulders 95A, 96A (FIG. 4) of the clamp 90 to interface with chamfered shoulders 95B, 96B (FIG. 4), respectively, of the external collar 56 and the base collar 40 to urge the external collar 56 and the base collar 40 closer to each other.
  • any sliding of the external collar 56 and the base collar 40 together can translate into sliding of the side wall 58 of the perimeter compressor 52 towards the sealing member 72 and the valve body 22.
  • the downward force (i.e., sealing force) applied to the sealing member 72 can be a function of the clamping force applied by the clamp 90 and can be adjusted with the wingnut 94 of the perimeter compressor 52 towards the valve body 22 as a function of the clamping force of the clamp 90 such that simple adjustment of the wingnut 94 can facilitate control of the sealing force between the sealing member 72 and the valve body 22.
  • the force imparted to the sealing member 72 can accordingly be adjusted more easily and more reliably than conventional actuator assembly arrangements where adjusting the force on a sealing member can be more difficult and time-consuming to accomplish and, if not done properly, can adversely affect the alignment of the sealing member.
  • the clamp 90 can be selectively removed from the base collar 40 and the external collar 56, as illustrated in FIG. 5, which allows the compressor assembly 50 to slide or be otherwise moved into the retracted position.
  • the compressor assembly 50 can then be slid into the retracted position which disengages the perimeter compressor 52 from the sealing member 72.
  • the actuator shaft 68 can be slid into the retracted position, which can facilitate extraction of the sealing member 72 (which is still attached to actuator shaft 68 at its distal end 76) from the actuator assembly 20.
  • the compressor assembly 50 is free to move independently of the actuator shaft 68. As such, when the actuator shaft 68 is slid to the retracted position, the corresponding upward movement of the sealing member 72 can cause the sealing member 72 to move towards the perimeter compressor 52 which can pull the compressor assembly 50 into its retracted position along with the actuator shaft 68.
  • the compressor assembly 50 and the actuator shaft 68 can be simultaneously moved into the retracted position by rotating the handle 70 in an unthreading or loosening direction (e.g., in a counter-clockwise direction). It is to be appreciated that the compressor assembly 50 and the actuator shaft 68 can be moved between their respective retracted and extended positions (either independently or simultaneously) with any of a variety of suitable alternative manual or automated arrangements.
  • compressor assembly 50 and the actuator shaft 68 are described as being slidable relative to each other, alternative embodiments are contemplated where the compressor assembly 50 and the actuator shaft 68 are mechanically linked together during retraction of the compressor assembly 50 (i.e., in order to inspect or replace sealing member 72), such that the retraction of the actuator shaft 68 would automatically retract the compressor assembly 50 together with the actuator shaft 68.
  • a new sealing member can then be installed on the tip portion 84 and the compressor assembly 50 and the actuator shaft 68 can be returned together to their respective extended positions.
  • the mechanical linkage between the compressor assembly 50 and the actuator shaft 68 can be released to release the compressor assembly 50 from the actuator shaft 68 to allow the compressor assembly 50 to engage with the sealing member 72 to reestablish the perimeter seal with the valve body 22.
  • the actuator shaft 68 is accordingly returned to the regular operation to facilitate control of the flow through the valve body 22.

Le compresseur périphérique peut coulisser entre une position rétractée et une position étendue. Le premier actionneur est couplé de manière fonctionnelle à une extrémité proximale de l'arbre d'actionneur pour faciliter le mouvement de l'arbre d'actionneur entre la position étendue et la position rétractée. L'élément d'étanchéité est associé à une extrémité distale de l'arbre d'actionneur de telle sorte que l'actionnement de l'arbre d'actionneur entre les positions rétractée et étendue facilite l'ouverture et la fermeture de l'élément d'étanchéité. Le deuxième actionneur est couplé de manière fonctionnelle au compresseur de périmètre pour faciliter le mouvement du compresseur de périmètre entre la position rétractée et la position étendue.
