    即使在理想的实验室测试环境下，不考虑法兰光洁度和密封垫负载，API 600
所规定的没有石墨的标准密封垫也被认为不适用于低排放场合。在测试了几种替代
密封垫后，我们选择了在我们的测试中表现性能最好的密封垫 - 带石墨填料通路
的波纹钢板密封垫。

　　Standard corrugated steel gaskets without graphite as specified in API 600 were found to be an unacceptable choice for low emission service, even under ideal laboratory test conditions, and regardless of flange finish and gasket load. After testing several alternative gaskets, we selected the best performing gasket in our tests - a corrugated steel gasket with graphite filled channels.

API 600 铸钢闸阀概述 及使用材料

1. 更安全、更紧密地阀杆密封。
   Safer and tighter stem seal.
2. 又短又窄的填料腔改善了密封性能。
   Short and narrow packing chamber improves sealing effectiveness.
3. 配置双填料和无泄漏的长寿命防泄漏填料腔或单填料。
   双填料：经过4000 psi压缩的两套石墨填料密封环。也可选择一个套环和leak-off，用于消除泄漏现象。
   单填料：在编织环之间放置三个或四个石墨环，密度80-90磅/立方英尺。
   Long-life leakproof packing chamber with double packing and leak-off or single set packing.
   Double packing: two sets of graphite packing rings compressed to 4000 psi. A lantern ring and leak-off provide option for removal of leakage, if any, from lower packing set.
   Single set packing: three or four graphite rings between braided rings, 80-90 lbs./cu. ft. density.
4. 动负载。
   两套免维护长期保持阀杆紧密性的Belleville弹簧。
   Live-loading.
   Two sets of Belleville springs keep stem tight for long periods of time without maintenance.
5. 两件式阀杆驱动可在线更新。
   Two-piece stem drive is renewable in-line.
6. 更有效的防泄漏阀体-阀帽连接。
   150磅级：石墨填充波纹钢板密封垫。
   300-600磅级：全封闭螺旋缠绕石墨填充不锈钢密封垫。
   Stronger leakproof body-bonnet joint.
   Class 150: Corrugated graphite-filled steel gasket.
   Class 300-600: Fully-encased spiral wound graphite-filled stainless steel gasket.
7. 300，600，900和1500磅级配置圆形阀帽和封闭密封垫。
   Classes 300, 600, 900 and 1500 have round bonnet and encased gasket
   钨铬钴合金6硬面的焊接装配阀座。
   Welded-in seats hardfaced with Stellite 6.
8. 柔性一件式楔板，采用钨铬钴合金6或13 CR硬面（DN200以上采用实心13 CR）。
   Flexible one-piece wedge, hardfaced with Stellite 6 or 13 CR (solid 13 CR up to 8").
9. 13 CR硬化的阀杆，接近镜面的抛光度，延长填料的使用寿命。
   13 CR hardened stem with mirror-like, burnished finish for longer packing life
