API600伞齿轮闸阀-上海鸿蝶阀门

　　api600伞齿轮闸阀

　　api600闸阀特点

　　通过阀座气密性的短程或远程保护提供完全关闭。

　　positive shutoff with visual or remote proof of seattightness.没有产品污染的气密性。

　　no product contamination absolute tightness.双阀座：合成橡胶-金属阀座加上金属-金属第二重密封。

　　dual seating.

　　elastomer-to-metal seat plus metal-to-metal secondaryseal.防火：如果第二重合成橡胶阀座在火灾期间被损坏，则金属-金属阀座还可以保证气密性。

　　fire safe.

　　the metal-to-metal seat ensures tightness if the secondaryelastomer seat is damaged during thefire.ptfe阀座镶嵌件：抗介质的腐蚀，在工作温度达到204°c时，具有很好的抗磨能力。

　　ptfe seat insert

　　resists corrosive media, has high abrasion resistance andoperates

　　up to +400°f (204°c).配置410不锈钢和密封焊接的阀座硬面。

　　seat hardfaced with ss 410 and seal welded.

　　易于在线进行阀门阀座维修 easy in-line valve reseating

　　阀座用410不锈钢进行硬面，通过焊接装配延长使用寿命。将楔板从阀体上拆卸后，磨损的软阀座镶嵌件就很容易更换了。在更换阀座镶嵌件之前，关闭流体，减轻压力。

　　seats are hardfaced with ss 410 and welded-in for lifetimeservice. a worn soft seat insert can easily be replaced afterremoval of wedge from the body. shut off flow and relieve pressurebefore replacing the seat insert.
