It connects and connects together to form one with fluorine bushing by fluorine lining both ends, corrosive solution is avoided to enter spherome surface corrosion sphere.
The utility model has the beneficial effects that by the way that several positioning pits are arranged in sphere outer wall, when fluorine bushing is coated on sphere
It squeezes into the fluorine bushing inner wall of molten condition when outer wall and forms positioning convex point in positioning pit, pass through both generation connection that be combined with each other
Power is tied, when sphere being avoided to rotate, fluorine bushing and the valve seat phase mutual friction of outer wall, which generate drag, to be caused between sphere and fluorine bushing
It generates removing to loosen or failure by rupture, first positioning carries out processing to the fluorine bushing of cladding and makes its surface on the basis of through-hole when production
As spherical shape, to guarantee the regularity of outer shape, be inserted into fluorine lining and fluorine bushing welding realize sealing, while fluorine lining with
Through-hole wall interference fit can guarantee adhesive force between the two, avoided when avoiding occurring in valve body in the case where negative pressure fluorine lining with
Through-hole wall separation.
