進口法蘭式針型閥性能參數 Performance parameter角式針型閥1.jpg
法蘭式針型閥垂直升降式而非旋轉升降式閥桿設計,避免閥門密封副間相對旋轉產生刮傷及減少密封填料的磨損,有效地提高了閥門及填料的使用壽命,間歇式填料系統設計,有效地減少填料的冷流及閥門的操作力矩,同時可利用系統介質對填料的作用實現更好的密封 RETZ The flange needle valve is designed as a vertical lifting valve stem instead of a rotary lifting valve stem to avoid scratches caused by the relative rotation of the valve sealing pairs and reduce the wear of the sealing packing, effectively improving the service life of the valve and the packing. The intermittent packing system is designed to effectively reduce the cold flow of the packing and the operating torque of the valve. At the same time, the effect of the system medium on the packing can be used to achieve better sealing
