The transmission device is fixed on valve body one end, and the pedestal is fixed on the other end；
The butterfly plate includes butterfly plate ontology, pressing plate, sealing ring, and butterfly plate is fixed on by two pins perpendicular to valve rod direction
The valve rod, and be located in the cavity of the valve body.
Further, there are two cotter way in the middle part of the valve rod, the butterfly plate one side is equipped with two perpendicular to valve rod direction
Pin hole.
Further, one middle side part of butterfly plate ontology have one perpendicular to valve rod direction terrace with edge, have on the terrace with edge parallel
Round hole in valve rod direction；There are annular groove and several threaded holes in the butterfly plate ontology other side, if the pressing plate passes through
Sealing ring is fixed on butterfly plate ontology by a dry soket head cap screw.
Further, the transmission device is fixed by screws in valve body one end, and the pedestal is fixed by screws in another
End.
In the present solution, top inner wall face and the valve rod of the Packing seat by hold-down grid pressure set on the valve body
Between outer surface, and the Packing seat is located at described close transmission device one end.
In the present solution, the gasket is set on pedestal by gasket pressing plate pressure, the material of the gasket is graphite composite pad.
The utility model has the advantages and positive effects of: due to the adoption of the above technical scheme, will when assembling product
Butterfly plate is fixed on valve rod to be fixed using the pin perpendicular to valve rod direction, so that the damage of butterfly plate sealing surface drops to most
It is low, substantially increase the reliability of product.
