Triple eccentric metal hard seal butterfly and the structure characteristics of pneumatic valve

, triple eccentric multi-layer metal hard seal butterfly butterfly plate of pneumatic valve sealing ring for soft hard cascading sheet metal, metal sealing and elastic sealing the dual advantages of no matter under the condition of low temperature and high temperature, has excellent sealing performance. And using three-dimensional eccentric structure, pneumatic valve seat and disc almost no friction, pneumatic valve internal parts when closing almost no damage; This structure is greatly improves the performance of the pneumatic valve in use. And has the close tight sealing function. , in the upper and lower parts of the pneumatic valve stem bushing, and each bushing wear and friction resistance is very small, the structure can prevent wear and adhesion, and at the same time increase the service life. , pneumatic valve sealing surface, adopts surfacing welding alloy steel or too hard alloy, sealing surface wear resistance, resistance to erosion and corrosion; Long service life. And unique structure, the switch moment of small, flexible operation, energy saving, convenient and not affected by medium pressure high, low, sealed performance is reliable. Can be used for opening and closing and regulating equipment.
