Transformer Radiator DN80 Butterfly valve
1.Application
Vacuum eccentric butterfly valve is mounted in pipe path between oil-immersed transformer and detachable radiator
and cooler or conservator .It is used for opening and closing oil path and being vacuum of transformer .
2.Technical parameters
1)Vacuum butterfly valve is into Ø40, Ø50, Ø80, Ø100, Ø125, Ø150, etc ,according to nominal diameter .
2)Nominal pressure of vacuum butterfly valve is 0.3Mpa.
Suitable temperature is between -40~105°c
3.Construction principle
Vacuum butterfly valve plate is fixed at valve pole .Turning valve pole with a spanner ,valve plate can turn over 90°
in valve housing to open and close valve plate .So open and close valve the oil path .Fixed block and fixed pin fitted
on top of valve ,valve plate allocated with valve housing by rubber ring .So sealing performance of vacuum butterfly
valve is good ,opening and closing is convenient ,and fixed position accurate .
4.Installation and operation
1)On side of vacuum butterfly valve with plate but not with shift axle joints with side side top of transformer .
2)Using butterfly valve ,first open valve cover ,then turn valve pole with a spanner to cause valve plate to rotate .
fixed block on valve pole limits each other with fixed pin on valve housing .Rotated angle is 90° .
When opening and closing butterfly valve ,pls turn valve pole to the limited position ,then fit valve cover .
For having limited slot on valve cover ,it can lock plate position .
