The butterfly board has cam function and can eliminate all the connection friction between sealed component and valve base during the valve gate moving to make it still have sealed function when frequently close and open. Two flanges would be saved by connecting the function of butterfly valve and extension tube. The second sealing would detect the sealing pressure online. The valve would take place of gate valve, break valve, globe valve. And it can match to use with any electric drive component, air drive component, and so on, to realize aim of long-distance controlling, adjusting or cutting a medium.
