主要性能 Main performance

进口导热油，蒸汽节流阀采用锥面密封，密封面不残留杂质在趋于关闭时，密封面具有自清洁作用，实现线性密封。铸件采用覆膜砂铸造技术，表面平整，机械性能良好，无气孔、砂眼和裂纹等缺陷 RETZ imported heat-transfer oil and steam throttle valve are sealed with conical surface. There is no residual impurities on the sealing surface. When the sealing surface tends to close, the sealing surface has a self-cleaning function to realize linear sealing. The casting adopts coated sand casting technology, with smooth surface, good mechanical properties, and no defects such as pores, sand holes and cracks

波纹管的结构 Structure of bellows

进口导热油，蒸汽节流阀 特点∶ Performance characteristics

锥面密封∶密封面不残留杂质在趋于关闭时，密封面具有自清洁作用，实现线性密封 Conical sealing: no impurities remain on the sealing surface. When the sealing surface tends to close, the sealing surface has a self-cleaning function to realize linear sealing

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

平衡双阀瓣密封∶小阀瓣缓解压力后带动大阀瓣轻松打开 Balanced double valve disc seal: after the small valve disc releases the pressure, the large valve disc can be easily opened

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
