Specific implementation mode
The utility model butterfly valve embodiment is described further referring to figs. 1 to Fig. 3.
A kind of butterfly valve, including valve body 1, valve rod 2 and valve seat 3, the valve seat 3 is interior to be equipped with flap 4, and the valve rod 2 is worn successively
Set on valve body 1, valve seat 3 and flap 4, the valve rod 2 includes first end 20, middle part 21 and the second end 22, in valve rod 2
Between portion 21 be arranged in flap 4, the valve seat 3 is made of rubber material, and the formation of valve body 1 is extended in the rear and front end of valve seat 3
Annular flange 30, the valve seat 3 is interior to be equipped with water flowing chamber 31, and the flap 4 is located in water flowing chamber 31, and the flap 4 includes centre
Cylinder setting linkage portion 40, and the left valve body 41 being wholely set with linkage portion 40 and right valve body 42, the water flowing chamber 31
Inner wall be equipped with plane boss 32, the upper and lower ends of the linkage portion 40 closely contact on plane boss 32, the left valve
Body 41 and the setting of right 42 semicircular in shape of valve body, the inner wall of arcwall face and water flowing chamber 31 closely contradict, and the linkage portion 40 is equipped with
For the straight slot 400 that valve rod 2 is worn, sealing ring 401, the middle part 21 of the valve rod 2 are equipped at the company mouthful at 400 both ends of the straight slot
Equipped with spline 23, the linkage portion 40 is equipped with spline 420, and the valve rod 2 is fixedly connected with flap 4 by spline 23.
Valve seat 3 is made of rubber material, it can be with the compactness between lifting valve base 3 and flap 4.In the water flowing of valve seat 3
It is equipped with plane boss 32 in chamber 31, the both ends of linkage portion 40 closely contradict on plane boss 32 on flap 4, and flap 4 is opening and closing
