主要性能 Main performance

(截至阀)进口导热油,蒸汽截止阀其关键部件金属波纹管，下端与阀杆组件采用自动滚焊焊接，上端与连接板自动滚焊焊接，在流体介质和大气之间形成一个金属屏障，确保阀杆零泄漏 RETZ metal bellows is the key component of the imported (heat transfer oil) steam stop valve. The lower end is automatically welded with the valve stem assembly, and the upper end is automatically welded with the connecting plate to form a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem

特点∶ Performance characteristics

阀瓣采用锥形设计，密封面与介质成流线形，密封性能更好 The valve disc adopts conical design, and the sealing surface is linear with the medium, with better sealing performance

双重的密封设计（波纹管+填料）若波纹管不幸失效，阀杆填料也会避免泄漏 RETZ Double sealing design (bellows + packing) if the bellows fails unfortunately, the stem packing will also avoid leakage

阀盖上自带有加脂接头，可直接对阀杆、螺母和轴套进行润滑  The valve cover is equipped with a greasing joint, which can directly lubricate the valve rod, nut and shaft sleeve
