(对夹 凸耳)暗杆式刀闸阀

(对夹，凸耳)进口暗杆式刀闸阀性能描述 Performance description

(对夹，凸耳)暗杆式刀闸阀的闸板关闭到位时通径无死角，根据流体分析设计冲力，自动冲解通径死角处杂物使介质通过更顺畅；内部设有弧形刮片使闸板在启闭工作全面积刮净表面使寿命更长，防止介质残留在阀腔，造成阀门开关不畅 retz品牌 (Hard seal, soft seal) When the gate of the non rising stem knife gate valve is closed in place, there is no dead angle in the diameter. According to the fluid analysis, the impulse is designed to automatically flush the debris at the dead angle of the diameter to make the medium pass more smoothly; Arc scraper is set inside to make the gate clean in the full area of the opening and closing work, so as to prolong the service life and prevent the medium from remaining in the valve chamber, causing the valve to open and close smoothly
