Summary: | The utility model provides an energy-saving multistage sealed stuffing box, and mainly aims to solve the problems of the prior stuffing box that the sealing effect is poor; the packing abrasion is serious; and the electric energy consumption is great. The multilevel sealed stuffing box is characterized in that a spherical sealing device (4) is movably connected with the interior of a spherical hole at the lower end of a packing cylinder (1) through the base (3) of the spherical sealing device; an O-shaped seal ring (5) which is in contact with a feed rod and a lip-type seal ring (6) are arranged in the hole of the spherical sealing device (4); and the O-shaped seal ring (5) in contact with the spherical hole at the lower end of a packing cylinder (1) is arranged outside the spherical sealing device (4). The energy-saving multistage sealed stuffing box provided by the utility model has the characteristics of good sealing effect, long packing service life, and low electric energy consumption. |
