ABSTRACT:
A pressure actuated packing assembly for use in sealing the annular area of fluid flow devices to provide and maintain an effective, long-term seal therein. The pressure actuated packing assembly is designed for use in chemically hostile environments, and for applications involving temperature and pressure differentials. The pressure actuated packing assembly automatically adjusts for wear, misalignment and service irregularities, while generally reducing the leakage and fugitive emission escape of fluid, flowing therethrough. The pressure actuated packing assembly is preferably constructed of an elastomeric energizer, a circular jacket member having an internal channel to substantially retain the elastomeric energizer and a rigid sealing insert member preferably disposed within the channel of the jacket member. The rigid sealing insert member, as a result of the system pressure within the fluid flow device, applies force to the energizer to radially expand the pressure actuated seal assembly to seal the annular area of the fluid flow device.
