Tri-eccentric bidirectional metal hard-sealed butterfly valve

Column:Media Focus Time:2015-01-28

Tri-eccentric bi-directional metal hard-sealed butterfly valve solves the problem that the metal hard-sealed butterfly valve with tri-eccentric structure can not achieve bi-directional sealing; the butterfly plate adopts truss structure with good rigidity and small deformation. The valve stem adopts through-axis, and the eccentric sleeve between the valve stem and butterfly plate is assembled with zero clearance connection, and the butterfly pin is positioned and fixed; The plate has good rigidity and small deformation, which can avoid the sealing separation caused by the clearance between butterfly plate and valve stem in reverse pressure. It can make the three-eccentric metal hard-sealed butterfly valve achieve bidirectional sealing. It can bear pressure in both positive and negative directions, and no internal leakage occurs in positive or reverse pressure.
