Accompanying drawing explanation
Fig. 1 is the structural representation of cold-air door for the utility model gas turbine.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model gas turbine comprises the first bolt 1 with cold-air door, valve plate 2, packing ring 3, butterfly plate 4, valve rod 5, the first seal ring 6, the first solid of rotation 8, valve body 9, the second seal ring 11, stuffing box 12, valve pushes away 13, pushing block 14, cover plate 17, valve pocket 20, the second solid of rotation 21, fixing by the first bolt 1 between valve plate 2 and butterfly plate 4, packing ring 3 is between valve plate 2 and valve rod 5, the first seal ring 6, the second seal ring 11, stuffing box 12 is all between butterfly plate 4 and valve rod 5, valve body 9 is positioned at the outside of butterfly plate 4, the first solid of rotation 8 and the second solid of rotation 21 are fixing, the first solid of rotation 8 and the second solid of rotation 21 are all positioned at valve pocket 20, valve pushes away 13 between stuffing box 12 and pushing block 14, cover plate 17 is fixed on one end of valve rod 5, valve pocket 20 is positioned at butterfly plate 4, the below of the first solid of rotation 8 is provided with noise reduction hole 19, can reduce noise like this, the phenomenons such as vibrations.
The shape of butterfly plate 4 is that one end part is flat, and the other end is provided with a projection 22, and intermediate portion is circular arc, and projection can conveniently be connected with miscellaneous part.
22 and second bolts 16 of projection are fixing, and the second bolt 16 is connected with a nut 15, prevent that like this second bolt 16 from unnecessary rotation occurring.
