Center line butterfly valve disassembly and assembly
Structure characteristics of the center line butterfly valve as the axis of the stem and disc center, ontology in the same position.
Simple structure, convenient manufacturing.
Common line with rubber butterfly valve which belongs to and so on.
as a center line butterfly valve is used to realize on-off and flow control components, piping system has been used in petroleum, chemical industry, metallurgy, water and electricity is widely used in many fields such as extremely.
the disadvantage is that because the butterfly plate and valve seat remain the state of extrusion, scratches, is apart from the big, fast wear.
To overcome the extrusion, scratches, ensure the sealing performance, basically use the elastic material such as rubber or ptfe seat.
Because of the limitation of structural features is not adapt to the high temperature, high pressure and corrosion resistance, wear resistance, etc.
