进口法兰式针型阀性能参数 Performance parameter角式针型阀1.jpg
法兰式针型阀垂直升降式而非旋转升降式阀杆设计，避免阀门密封副间相对旋转产生刮伤及减少密封填料的磨损，有效地提高了阀门及填料的使用寿命，间歇式填料系统设计，有效地减少填料的冷流及阀门的操作力矩，同时可利用系统介质对填料的作用实现更好的密封 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
