產(chǎn)品詳情 Product details
法蘭式針型閥垂直升降式而非旋轉(zhuǎn)升降式閥桿設(shè)計,避免閥門密封副間相對旋轉(zhuǎn)產(chǎn)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(tǒng)設(shè)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(tǒng)介質(zhì)對填料的作用實現(xiàn)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
進(jìn)口法蘭針型閥主要特點DESIGN FEATURES
設(shè)計符合ASME VIII,ANSI B16.34/B16.5B31.3 和API6D的相關(guān)要求
不旋轉(zhuǎn)閥芯,以確保壓力關(guān)閉的緊密性,不旋轉(zhuǎn)閥桿承受超高壓和超高溫
閥體特殊的加強設(shè)計確保壓力密封可靠性更高
填料位于閥桿的下方,以隔絕螺紋與介質(zhì)的接觸
閥桿螺紋為滾壓制減少磨損長
手柄大大減少操作扭矩
閥桿和填料函接頭和閥體是相扣設(shè)計,防止閥桿脫離閥門
