Abstract
A mechanical packing sealing assembly having an axially movable pressure adjustment element for applying a pressure to a packing assembly, a packing pressure adjustment element for selectively axially moving the pressure adjustment element, and position locking element for defining an axially outboard most position of the pressure adjustment element. The mechanical packing sealing assembly can also include a plurality of packing elements forming a packing assembly that are sized and configured for seating within a recess of stationary equipment and about the pressure adjustment element.
Claims5
A method for regulating an axial pressure applied to a packing assembly in a fluid regulating device, wherein the fluid regulating device includes a gland element and a stationary equipment having a recess formed along an inner surface, comprising
- providing a pressure adjustment element suitable for mounting in the recess of the stationary equipment and sized for mounting a packing assembly,
- providing a packing pressure adjustment element for moving the pressure adjustment element toward the gland element,
- providing a position locking element for defining an outboard most position of the pressure adjustment element,
- configuring the pressure adjustment element to be movable axially in response to a pressure of a process fluid in the stationary equipment applied to a piston area of the pressure adjustment element independent of the gland element, and
- configuring the piston area of the pressure adjustment element to apply an axial force to the packing assembly mounted in the stationary equipment and coupled to the pressure adjustment element during use based on the pressure of the process fluid.
