进口暗杆波纹管截止阀 美国RETZ瑞茨

　　RETZ工业/美国瑞茨，我们一直致力于流体控制领域的持续创新，始于2005……进口暗杆式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 The double sealing design of the non risingstem steam corrugated pipe globe valve with packing on the corrugated pipe hasdouble safety, making the sealing at the valve stem safer and more reliable,and complying with international sealing standards

　　进口暗杆式波纹管截止阀主要性能 Main performance

　　(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 imported Non rising stem steam bellowsstop valve is sealed with a conical surface, without residual impurities. Whenit tends to close, it has a self-cleaning effect, and has an amplificationeffect when the axial force of the valve stem is converted into the sealingforce. A larger seal specific pressure can be obtained 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

　　1.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 sealedin a closed space, not directly affected by the medium, pressure andtemperature

　　2.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 linearwith the medium, with better sealing performance

　　3.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 failsunfortunately, the stem packing will also avoid leakage

　　4.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 witha greasing joint, which can directly lubricate the valve rod, nut and shaftsleeve
