| description | The invention relates to a bidirectional sealing frictionless butterfly valve mainly solving the technical problems of leakage, and the like caused by easy elastic deformation of a valve seat because of overlarge medium pressure at the outlet end of a traditional butterfly valve. The bidirectional sealing frictionless butterfly valve is characterized in that a gap is formed between a valve seat and a butterfly board, a bulk cavity is arranged in the valve seat and internally provided with a frame, one end surface of the frame is attached to the valve body, one end surface of the frame, which is attached to the bulk cavity of the valve seat, is provided with a circular groove, an oil hole which penetrates through both ends of the frame and is communicated with the circular groove is arranged on the frame, an oil inlet is arranged on a position of the valve body, which corresponds to the oil hole of the frame, communicated with the oil hole and provided with an oil hole joint, one end of the oil hole joint is f |
