Abstract：In order to prevent the valve leakage, usually using packing seal between the valve stem and valve cover. According to the sealing principle of stuffing box, the selection of the valve stuffing size was described, and the theoretical calculation methods of the valve stuffing box was briefly introduced, specifically including packing pressing force calculation method and calculation method of the friction between stem and packing, and the relevant formulas and soft packing correlation calculation data was given in this paper.
Key words：valve；stuffing box；sealing
