Technical Field

The utility model relates to a stuffing box technical field especially relates to a stuffing box convenient to dismantle maintenance.

Background

The main materials of the stuffing box comprise carbon steel and stainless steel, and the main performance parameters of the stuffing box comprise pressure grade and nominal shaft diameter. The stuffing box seal consists of basic parts such as a stuffing box body, stuffing, a gland, a bolt and the like, the stuffing arranged between the box body and the rotating shaft generates radial extension under the axial extrusion of the bolt force and the gland, so that the stuffing is tightly attached to the periphery of the rotating shaft, and lubricating oil added from an oil cup can enable a layer of extremely thin oil film to be formed between the contact surfaces of the stuffing and the rotating shaft when the shaft rotates, thereby not only having the lubricating function, but also preventing the medium in the kettle from escaping outwards and preventing the gas outside the kettle from permeating.

However, when the existing stuffing box is used, the inside of the stuffing box needs to be cleaned, the stuffing box is inconvenient to disassemble integrally, the stuffing box cannot be cleaned well, and the subsequent use of the stuffing box can be influenced.

SUMMERY OF THE UTILITY MODEL
