It is provided with for the valve gap in gap between sealed valve body and valve rod on described valve body at valve rod, described valve gap fixedly mounts
Having pressing plate part, described pressing plate part is rotatablely equipped with handwheel, described handwheel sleeve is located at valve rod and stretches out on one end of valve body, and handwheel
Being connected by leading screw with between valve rod, described valve gap is provided with stuffing box with contacting out of valve stem contacts, sets in described stuffing box
Being equipped with spacer ring, the two ends up and down of described spacer ring are provided with filler, and described stuffing box is provided with conflict near one end of pressing plate part
The gland of filler.
This utility model is further arranged to: described stuffing box is arranged at valve body contact near one end lateral surface of valve body
There is sealing ring.
This utility model is further arranged to: described pressing plate part is positioned at handwheel and is provided with the bearing being connected with handwheel.
This utility model is further arranged to: described pressing plate part is positioned at bearing the oil filler point being provided with connection bearing.
This utility model has an advantage that the setting by stuffing box, spacer ring and filler, it is possible to valve rod and valve gap it
Between gap seal, and filler be mounted at the two ends of spacer ring arrange, it is possible to carrying out secondary between valve rod and valve gap
Seal so that further increase the sealing between valve rod and valve gap, and valve rod can be reduced at valve gap, move the damage caused
Wound, by being connected for leading screw between handwheel with valve rod so that handwheel rotate through leading screw effect, it is possible to make valve rod at valve body
Inside move up and down, and drive flashboard to open or close, by the setting of bearing, it is possible to alleviate the stress effect of hand wheel rotating, logical
Cross the setting of sealing ring, it is possible to increase the sealing effectiveness between stuffing box and valve body, and improve further between valve gap and valve body
Sealing effectiveness, by arranging oil filler point on pressing plate part, enabling bearing is carried out oil injection operation, it is to avoid bearing excessively uses
Unlubricated effect, and the using effect of bearing can be improved.

Detailed description of the invention
Referring to figs. 1 through shown in 4, the self-pressure-sealed gate valve of one of the present embodiment, it includes valve body 1, is arranged in valve body 1
Valve seat 2, the flashboard 3 being arranged on valve seat 2 and be arranged on valve body 1 valve rod 4 for the flashboard 3 that links, on described valve body 1
It is provided with at valve rod 4 for the valve gap 5 in gap between sealed valve body 1 and valve rod 4, described valve gap 5 is installed with pressure
Plate 6, described pressing plate part 6 is rotatablely equipped with handwheel 7, and described handwheel 7 is set in valve rod 4 and stretches out on one end of valve body 1, and hands
Wheel 7 is connected by leading screw between valve rod 4, and the contact that described valve gap 5 contacts with valve rod 4 goes out to be provided with stuffing box 8, described filler
Being provided with spacer ring 9 in case 8, the two ends up and down of described spacer ring 9 are provided with filler 10, and described stuffing box 8 is near the one of pressing plate part 6
End is provided with the gland 11 of conflict filler 10.
Described stuffing box 8 is provided with sealing ring 12 near one end lateral surface of valve body 1 with valve body 1 contact position.
Described pressing plate part 6 is positioned at handwheel 7 and is provided with the bearing 13 being connected with handwheel 7.
Described pressing plate part 6 is positioned at bearing 13 oil filler point 14 being provided with connection bearing 13.
By using technique scheme, by stuffing box 8, spacer ring 9 and the setting of filler 10, it is possible to valve rod 4 and valve
Gap between lid 5 seals, and filler 10 is mounted at the two ends of spacer ring 9 arranging, it is possible to valve rod 4 and valve gap 5 it
