The filler valve deck is internally provided with threaded hole as a further solution of the present invention, outside the valve rod
Side is provided with screw thread, and the screw thread matches with the screw thread in threaded hole.
Compared with prior art, the utility model has the beneficial effects that
The utility model structure is simple, is connected between hand lever and valve rod by interior hexagonal flush end tight fixed bolt, while filler
It is fastenedly connected between valve deck and valve body by hexagonal locknut, keeps valve easy to disassemble on the whole, install convenient is also beneficial to simultaneously
Maintenance activity after valve damage, and discharge port is provided with access ramp, facilitates the closure and sealing of valve.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of welded type flange cut-off valve.
In figure: 1- valve body, 2- filler washer, 3- filler, 4- filler valve deck, 5- valve rod, 6- hand lever, hexagonal flush end is tight in 7-
Determine bolt, 8- hexagonal locknut.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the utility model embodiment, a kind of welded type flange cut-off valve, including valve body 1, the valve body 1
Upper inner is provided with mounting groove, and valve rod 5 is equipped in the mounting groove, and 5 top of valve rod is equipped with hand lever 6, the hand
The right side of bar 6 is internally provided with interior hexagonal flush end tight fixed bolt 7, and the left end of the interior hexagonal flush end tight fixed bolt 7 connects with valve rod 5
Touching is provided with filler valve deck 4 between 5 middle part of valve rod and valve body 1, the filler valve deck 4 is set in 5 outside of valve rod, and fills out
4 outside of material valve deck is fixedly connected with valve body 1, is provided with filler 3 in the valve body 1 on the downside of filler valve deck 4, and the filler 3 wraps
Valve rod 5 is wrapped up in, filler washer 2 is provided on the downside of the filler 3,5 lower end of valve rod passes through filler washer 2 and 5 lower end of valve rod
