主要性能 Main performance

进口导热油，蒸汽波纹管闸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 Imported heat transfer oil, steam gate valve and its key components are metal bellows. The lower end is automatically welded with the valve stem assembly, and the upper end is automatically welded with the connecting plate. A metal barrier is formed between the fluid medium and the atmosphere to ensure zero leakage of the valve stem

波纹管的结构 Structure of bellows

进口导热油，蒸汽波纹管闸阀特点∶ Performance characteristics

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  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

波纹管防护型空间设计∶波纹管被密封在密闭的空间里，不受介质、压力、温度的直接影响 Bellows protective space design: the bellows is sealed in a closed space, not directly affected by the medium, pressure and temperature

所有波纹管出厂时根据IS015848 A级标准100%通过逸散性测试所有波纹管组件和阀门100%通过标准A级测试，确保零泄漏 All bellows pass 100% of the leakage test according to is015848 class a standard when leaving the factory. All bellows components and valves pass 100% of the standard class a test to ensure zero leakage

波纹管组件焊接∶微电脑控制焊接速度，保证核心部件质量 Bellows assembly welding: microcomputer controls the welding speed to ensure the quality of core components
