The utility model devises a kind of high temperature resistant butterfly valve, is made of valve body, butterfly plate, valve rod, is equipped with to flow into valve body and lead to
Road and flow pass are equipped with butterfly plate between flow channel and flow pass, butterfly plate side is equipped with valve rod, leads between butterfly plate and valve rod
Bolt to be crossed to be fixedly connected, valve interior wall is equipped with annular groove in flow channel one end, and circular metal plate is equipped in annular groove,
It is characterized in that：Circular metal plate is made of hollow guide hole and solid block, and hollow bore is as medium via hole, solid block table
Face is equipped with thermal insulation panel, is bolted between thermal insulation panel and solid block.
Further, the hollow guide hole and solid block are square shape, the table of hollow guide hole and solid block
The sum of area is equal, and mutual dislocation is arranged between hollow guide hole and solid block.
Further, the thermal insulation panel is specially square shape nanometer micropore thermal insulation board.
The utility model on valve body flow channel by being arranged circular metal plate, and circular metal plate is by hollow guide hole and reality
Heart block forms, and hollow guide hole is equal with the sum of the surface area of solid block, mutual dislocation between hollow guide hole and solid block
Setting, it is ensured that the circulation of medium and the heat insulation of metallic plate are protected simultaneously；Thermal insulation panel uses square shape nanometer micropore
Thermal insulation board, nanometer micropore thermal insulation board heat-proof quality is stable and price is economical, it is ensured that normal operation of the butterfly plate under worst hot case makes
With very convenient.
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art is come
Say, still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
