On valve gap 2, valve rod 4 bottom is in valve pocket, is provided with packing seal assembly, packing seal assembly bag between valve rod 4 and valve gap 2
Include filler 41, and cover 42 for positioning the filler of described filler, and for positioning the hold-down grid 43 of described filler set 42.
Filler in packing seal assembly is used for ensureing that the sealing between valve rod 4 and valve gap 2, filler set 42 and hold-down grid 43 are used for
Described filler is positioned, so that filler is fixed, prevent filler from producing pine in the friction process long-term with described valve rod 4
Dynamic；Thus lifting its sealing effectiveness, so that gate valve is difficult to produce medium leakage and permeate, ensureing that valve body 1 moves, extend valve body 1
Service life.
Described valve gap 2 is fixedly arranged above support 51, and valve rod 4 top is positioned inside support 51, is provided with use above support 51
In the protective cap 52 protecting described valve rod 4 end.Described operating mechanism includes operating handwheel 53, and coaxial with operation handwheel 53
The umbrella tooth 54 connecting, and it is set in the valve stem nut 55 on valve rod 4 upper end.Described valve stem nut 55 outer end is nibbled with umbrella tooth 54
