Pressure balanced self-regulating mechanical packing sealing assembly

Abstract

A mechanical packing sealing assembly includes an axially movable pressure adjustment element having a main body that is sized and configured for seating within the recess formed in the stationary equipment. The main body can include a radially outwardly extending first flange element formed at a first end that is sized and configured for engaging with a radial surface of stationary equipment of a fluid regulating device and a radially inwardly extending second flange element formed at an opposed second end and forming a piston area for being exposed to a pressure of a process fluid in the stationary equipment. The second flange element can selectively apply an axial force to the packing assembly when coupled to the main body, and the pressure adjustment element is movable axially as a function of the pressure of the process fluid applied to the piston area.
