Hard seal butterfly valve
1. Overview of hard seal butterfly valves
Our company's internationally advanced three-dimensional adjustable two-way hard-sealed butterfly valve adopts the "inclined elliptical disc radial dynamic balance sealing system". During the opening and closing process, the butterfly plate achieves no slip friction and jam between the butterfly plate seal and the seat seal, and the pressure angle on the sealing surface is greater than the friction angle, so that the opening resistance of the butterfly plate is extremely low. The sealing surface adopts multiple seals and is processed by a high-precision numerical control device to form an elliptical cross-section sealing ring, which forms a sealing pair with the metal sealing surface of the valve seat. As a result, the sealing structure produces plastic deformation under high pressure conditions. Under high temperature or low temperature conditions, there is no stamping stress, welding stress, elastic annealing or brittle fracture, and the butterfly valve inlet and outlet bidirectional seal is reliably realized. leakage.
