With when motor 101 does not work, butterfly plate 10 is in the state concordant with 13 both ends of valve body, the sealing ring 7 and valve of 10 side wall of butterfly plate
Body sealing surface 6 offsets, since valve body sealing surface 6 is inclined-plane, under the extruding of water flow pressure, so that sealing ring 7 and valve seal
Face 6 offsets closely, and since sealing ring 7 and pressing plate 8 and 10 side wall of butterfly plate offset, and pressing plate 8 is by hexagon socket head cap screw 12
Be fixedly connected with the side wall of butterfly plate 10 so that sealing ring under the extruding force of pressing plate 8 without departing from butterfly plate 10 so that whole is close
Sealing property is guaranteed, due to the presence of filler 4 and upper bushing 5 and lower bushing 14, so that will not between valve rod 11 and valve body 13
There is direct friction, and to be bonded between valve rod 11 and valve body 13 closely, increases sealing performance, while making valve rod
The service life of 11 grades of valve bodies 13 increases.
When motor 101 breaks down, it can be rotated turning handle 103, rotate the convex block 106 of its side wall, so that block 105
No longer offset with convex block 106, at this time can by pulling turning handle 103, so that telescopic rod 107 extends, and realize the second worm gear 109 with
Valve rod 11 is meshed, and since convex block 106 is mobile, so that shaft 104 is during rotation, convex block 106 will not connect with block 105
Touching, so that shaft 104 can smoothly drive the second worm gear 109 to rotate, so that valve rod 11 rotates, realization is manually released and is cut
Stream, can be used for the processing of emergency, when due to 101 normal use of motor, convex block 106 offsets with block 105, and block
105 attract convex block 106, so that the second worm gear 109 will not be contacted with valve rod 11, guarantee not occurring in device operational process mutually
Interference.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
