The sealing surface of the valve plate and the valve seat is an oblique conical structure, and a temperature-resistant and corrosion-resistant alloy material is deposited on the oblique conical surface of the valve plate; the spring fixed between the adjusting ring plate and the adjusting bolt on the pressure plate is arranged together. This structure effectively compensates for the tolerance band between the sleeve and the valve body and the elastic deformation of the valve stem under the medium pressure and solves the sealing problem existing in the process of transporting the valve in the bidirectional interchangeable medium. High-temperature butterfly valve with soft T-shaped multi-layer stainless steel sheet on both sides of the seal ring, with a metal seal and double the advantages of soft-sealed, both in low temperature and high temperature conditions, have zero leakage of sealing performance. Test proves pool positive flow state, the pressure on the sealing surface is generated by the torque of the transmission and the effect of the medium pressure on the valve plate. Positive media pressure increases when the valve plate oblique cone surface and seat sealing surface squeeze the more tight, the better the sealing effect.
