一、美标法兰闸阀产品介绍：①产品设计制造符合美国国家标准ANSIB16.34，美国石油学会标准AP16D和API600要求。②结构紧凑、体积小、刚性好、密封安全可靠。③关闭件（闸板）采用弹性结构，在工作中能自动补偿由于异常负荷或温度引起的阀体变形。因此，密封可靠，并且不会产生闸板楔柱。④公称通径大于等于NPS1011，压力级400磅级和公称通径大于等于NPSS611、压力级150～2500磅级的手动阀门，其操做装置中配有滚动轴承，启闭轻松。⑤主体材料、内件材料、填料、垫片、紧固件的材料可根据用户要求或实际工况条件合理组合。⑥阀座可为更掀式阀座，可任意组合与关闭密封面材质配对，以满足工况要求，延长使用寿命。二、标准设计与制造结构长度法兰尺寸对焊连接尺寸压力温度等级试验与检验AP1600ANS1B16.10ANS1B16.5aANS1B16.25ANS1B16.34AP1598三、压力试验：公称压力强度试验水密封试验气密封试验MPaLbf/in2MPaLbf/in2MPaLbf/in21503.14502.23150.5～0.760～1003007.811255.681560015.3222511.2163090023.1335016.82440150038.4557528.14080250064.6936747.46873四、主要零件材料及性能：壳体ASTMA216WCBASTMA351CF8闸板WCBCF8CF8MMonel阀杆F6aF304F316MonelF304闸板密封面13Cr13CrSTL304STL316STLMonel304304STL阀座密封面13CrSTLSTL304STL316STLMonel304STLSTL壳体ASTMA351CF3ADTMA351CF8MASTMA351CF8闸板阀杆F304LF316F316L闸板密封面304L304LSTL316316STL316L316LSTL阀座密封面304LSTLSTL316STLSTL316LSTLSTL五、美标闸阀ANS1Class150~ANS1Class300主要外形尺寸：ANS1Class150NPS221/234681012141618202426283032364042LRF17819120329267292330356381406432457508559610610660711762787BW216241283305403419457502572610660711813864914914965101610671118手动H140049051058577595511601375157017651980---------Do200200250300350350400450500600700---------伞齿轮H2--------166819202115221526002908304631363293372640604229电动H3--------166819202115221526002908304631363293372640604229ANS1Class300NPS221/234681012141618202426283032364042LRF216241283305406419457502762838914991114312451346169715241727--BW216241283305406419457502762838914991114312451346169715241727--手动H14705255356358051025123014601645-1840---------Do200200300300350400450500600-600---------伞齿轮H2----------1935215525722908310031353293---电动H3----------1935215525722908310031353293375441204530六、美标闸阀ANS1Class600主要外形尺寸：ANS1Class600NPS221/2346810121416182024262830LRF292330356432559660787838889990109211941397144815491651BW292330356432559660787838889990109211941397144815491651手动H1474530547703913107712761499--------Do250250300350450500600680--------伞齿轮H2-------1470162502089221126162921296030503112电动H3-------1470162502089221126162921296030503112七、美标闸阀ANS1Class900主要外形尺寸：ANS1Class900NPS221/23468121416182024LRF36841938145761073796510291130121713211549BW368419381457610737------手动H162070569582510651318------Do300350350400500600------伞齿轮H2----800940169118772143231027503150电动H3----800940169118772143231027503150八、美标闸阀ANS1Class1500主要外形尺寸：ANS1Class1500NPS2346810121416182024LRF371473549---------BW------------手动H161470592711911524185421842216----Do------------伞齿轮H2---1191152418542184-----电动H3---119115241854218422162316262028403310九、美标闸阀ANS1Class2500主要外形尺寸：ANS1Class2500NPS234681012LRF451578673914102212701422BW451578673914102212701422手动H1630890-----Do-------伞齿轮H2-------电动H3--1911347144516921914
