暗杆式蒸汽波纹管截止阀的波纹管加填料双重密封设计，具有双重，使得阀杆处的密封更安全可靠，并符合国际密封标准 Thedouble sealing design of the non rising stem steam corrugated pipe globe valvewith packing on the corrugated pipe has double safety, making the sealing atthe valve stem safer and more reliable, and complying with internationalsealing standards
进口暗杆式波纹管截止阀主要性能 Mainperformance
(暗杆式)进口蒸汽波纹管截止阀采用锥面密封，不残留杂质，在趋于关闭时，具自清洁作用，使阀杆轴向力转化为密封力时具有放大作用。在同样的压力下可获得更大的密封比压。关闭更轻松，密封性能更佳 RETZ importedNon rising stem steam bellows stop valve is sealed with a conical surface,without residual impurities. When it tends to close, it has a self-cleaningeffect, and has an amplification effect when the axial force of the valve stemis converted into the sealing force. A larger seal specific pressure can beobtained under the same pressure. Easier closing and better sealing performance
进口暗杆式波纹管截止阀性能特点Performance characteristics
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, notdirectly affected by the medium, pressure and temperature
阀瓣采用锥形设计，密封面与介质成流线形，密封性能更好 Thevalve disc adopts conical design, and the sealing surface is linear with themedium, 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 RETZDouble 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 greasingjoint, which can directly lubricate the valve rod, nut and shaft sleeve
