Abstract

Sealing system with modified stuffing box for control or shut-off fittings, comprising inter alia a fixed part of a housing (3) with a stuffing box space for sealing the axially or alternatively rotatingly movable spindle (1) in the form of a split packing (8, 11), a gland (2) screwed to the housing (3), and a lubricating box (13) which, in the case of a packing split at some point along its length, is arranged in the stuffing box space. To improve the sealing of the spindle and, in particular, to achieve a higher standard of long term tightness, the following further features are implemented: a) the split packing in each case consists of individual packing rings composed of a basic seal material and in each case a lower and upper compartmentalisation ring for each of the two parts of the packing b) a pasty lubricant is incorporated into the packing, c) a continuous supply of lubricant is provided in the space between the two parts of the packing via the lubricating box, d) the packing is compressed and readjusted by means of spring force n
