Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-3, in the utility model embodiment, a kind of Pneumatic butterfly valve of achievable high-speed switch, including valve body 6
With connecting rod 1, is provided with valve plate 8 and valve rod 12 in valve body 6, valve rod 12 is structure as a whole with valve plate 8, the upper end stretching of valve rod 12 and
Pneumatic actuator 5 is connected, and pneumatic actuator 5 drives whole valve rod to be rotated, and the lower end of valve rod 12 is stretched out to be connected with bottom 11
Connect, the lower end of valve rod 12 and bottom 11 are directly provided with rolling bearing 10, and for rolling bearing 10 as buffering, coordinating valve rod 12 to rotate can be with
Frictional force when valve rod 12 rotates is reduced, accelerates the speed that valve plate 8 rotates, the outside of valve plate 8 is provided with sealing ring 7, and sealing ring 7 strengthens
Sealing between valve plate 8 and valve body 6, realizes the function of dash, and valve rod 12 is externally provided with fixed cover 9, the upper and lower surface of fixed cover 9
