Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
The eccentric soft and hard seal wafer type of a kind of multipurpose butterfly valve, as shown in Figure 1, comprise valve body 1, butterfly plate combination 3, valve plate 5 and valve shaft 14, be provided with Lower shaft sleeve 2 and Upper shaft sleeve 8 between valve body 1 and the valve shaft 14, be provided with pressure ring 4 between butterfly plate combination 3 and the valve plate 5, valve plate 5 is contained in the valve body 1, be fixed on the valve shaft 14 with direct selling 7 and hexagon socket head cap screw 6, it is characterized in that: as shown in Figure 5, the selfsealings Stuffing box 19 that also comprises the top that is located at valve body 1, be provided with O type circle 9 and spacer ring 10 in the selfsealings Stuffing box 19, spacer ring 10 can float by easy on and off, extruding O type circle 9 makes the internal diameter of O type circle 9 and outside dimension all can remain the optimal seal effect according to the change in pressure of valve insertion; Selfsealings Stuffing box 19 tops also are provided with differential 11, and valve body 1 top is fixing by hex head bolt 12 and stud bolt 13, and valve shaft 14 tops are provided with flat key 15 and driving head 16.
