Three eccentric metal seal butterfly valve features
- Feb 03, 2018 -

High-performance three eccentric two-way hard sealing butterfly valve, characterized in that: the seat ring seal by the soft T-ring multi-layer stainless steel sheet on both sides. 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.
