Product introduction:
In order to solve the problem of extrusion between butterfly plate and valve seat of concentric butterfly valve, a single eccentric butterfly valve is produced. Its structural feature is that the shaft center of valve rod deviates from the center of butterfly plate, so that the upper and lower ends of butterfly plate no longer become rotary axis, disperse and reduce the excessive extrusion between upper and lower ends of butterfly plate and valve seat.
working principle:
Double clip single eccentric butterfly valve The structural feature of the valve stem is that the axis of the valve stem deviates from the center of the butterfly plate, which makes the upper and lower ends of the butterfly plate no longer become the rotary axis, disperses and reduces the excessive extrusion between the upper and lower ends of the butterfly plate and the valve seat, and solves the extrusion problem between the butterfly plate and the valve seat of the concentric butterfly valve. However, the single butterfly valve and valve seat are not used in the whole process.
Product features:
one Its design is novel, reasonable, unique in structure, light in weight and quick in opening and closing.
two Small operating torque, convenient operation, labor saving and dexterous.
three It can be installed in any position and easy to maintain.
four The sealing element can be replaced, the sealing performance is reliable, and the two-way sealing is zero leakage.
five The sealing material is aging resistant, corrosion resistant and has long service life.
