结构特征 structure characteristics

产品的设计符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相关要求retz品牌  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

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 The design of vertical lifting valve stem instead of rotary lifting valve stem avoids scratches caused by relative rotation between valve sealing pairs and reduces the wear of sealing packing, effectively improving the valve

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 Intermittent packing system design can 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

耐高温压高、阀采用优质锻钢制造，阀杆做渗碳处理，阀芯全部焊STL合金，密封性和反复性好 High temperature and pressure resistance, the valve is made of high-quality forged steel, the valve stem is carburized, and the valve element is all welded with STL alloy, with good sealing and repeatability

气体介质阀座采用PTFE、PEEK软密封材料提高本阀的密封性 PTFE and PEEK soft sealing materials are used for the gas medium valve seat to improve the sealing performance of the valve
