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 double valve block structures, including valve body 1, the interior left side of the valve body 1
It is provided with mounting hole 1, and right side is provided with mounting hole 2 12 in valve body 1, the mounting hole 2 12 is arranged in mounting hole 1
Downside, is mounted on valve rod 3 in the mounting hole 1 and mounting hole 2 12, one end of the valve rod 3 be located at 1 inside of valve body and
Flap 2 is installed, the other end of the valve rod 3 through valve body 1 and is equipped with hand lever 8, is arranged with filler pressure in the middle part of the valve rod 3
Lid 7 is provided with hexagon thin nut 6 on the outside of the gland 7, and one end of the gland 7 is arranged inside valve body 1, and
