The end of the rotation axis of driving device 1 is slightly below the inner wall of valve body 2, so that the fixing end of valve plate 8 is close to 2 inner wall of valve body.
It should be noted that being not limited to the set-up mode between above-mentioned valve plate 8, rotation axis and shaft, can such as use
Directly run through the shaft at 2 both ends of valve body, the one end of shaft and the rotation axis connection of driving device 1, and can rotate with it, then adopt
It is axial along shaft with four valve plates 8, it is respectively welded in shaft, and form four and be used to collect and transport the V-type knot of material
Structure, equally can be achieved above-mentioned purpose.
Based on the above technical solutions, the outer wall of the valve body 2 of shaft side is provided with the annular with outwardly convex
The gland 3 of structure, so that 2 inner wall of valve body fits closely and by loop configuration fixed rotating shaft with valve plate 8；
Packing ring 4 and the gland 5 for compressing packing ring 4 are provided between gland 3 and shaft.
Based on the above technical solutions, 2 top of valve body and bottom are respectively arranged with feed inlet 12 and discharge port 13.
Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
