进口美标法兰150LB铸钢WCB和A216截止阀一、进口美标截止阀概述品牌：美国威盾VTON进口美标截止阀，APIflangedglobevalve，也叫美标磅级截止阀，美标法兰截止阀，美标铸钢截止阀，150Lb截止阀，300LB截止阀，是指设计制造符合美国国家标准ANS1B16.34,美国BS1873的截止阀。阀体外形为桶形或流线形造型美观。流通形状为直通式。流体阻力小。二、进口美标截止阀技术参数接口尺寸:DN15－DN1000；1寸-25寸压力等级:PN10－PN320┃150LB－1500LB；温度范围:－196℃－＋500℃；连接方式:法兰式；进口铸钢截止阀使用介质：水、油品、气体、蒸汽、燃气等。进口铸钢截止阀应用石油、化工、液化气、给排水、食品、制药、发电、造纸、城建、矿产、锅炉蒸汽系统、市政各部门等。三、进口美标截止阀优点：1、流体阻力小，其阻力系数与同长度的管段相等。2、结构简单、体积小、重量轻。3、紧密可靠，目前闸阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。4、操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。5、维修方便，闸阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。6、在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。7、适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用，球旋转90度时，在进出口处应全部呈现球面，从而截断流动。四、进口美标截止阀应用标准计与制造ANSIB16.34BS1873结构长度ANSIB16.10法兰尺寸ANSIB16.5对焊连接尺寸ANSIB16.25压力-温度ANSIB16.34试验-检验API598美标截止阀性能规范公称压力PN(Lb)强度试验水密封试验气密封试验MPaLbf/in2MPaLbf/in2MPaLbf/in21503.04302.23150.4-0.760-1003007.711105.781560015.3222011.3163090023.0333017.02445150038.4556028.24080250064.0925547.06790五、进口美标截止阀结构尺寸图美标截止阀连接尺寸150LB连接尺寸公称通径(DN)150Lb凸面法兰（RF)主要尺寸（mm）重量(Kg)mminLDD1D2bn-φdHD0151/21088960.53511.24-162411006.9203/41179869.94312.74-162411009.825112710879.25114.24-1624212513.53211/41401178963164-1628016019.54011/216512798.67317.54-1628616028.5502203152120.792194-19368200186521/2216178139.710522.44-1938720030803241190152.4127244-19411250411004292229190.5157244-19454250641255356254216.0186248-22.5455350861506406279241.321625.48-22.55413501132008495343298.527028.48-22.565145017825010622406362.032430.212-25.480045027030012698483431.83813212-25.4123160035035014787533476.34133512-29145060046040016914597539.847036.626-291645600590300LB连接尺寸公称通径(DN)300Lb凸面法兰（RF)主要尺寸（mm）重量(Kg)151/21529566.53514.24-162411407.7203/417811782.543164-1924114011.3251203123895117.54-1928316016.83211/421613398.563194-1932020021.24011/2229155114.37320.64-22.532220032.65022671651279222.48-19399200256521/2292190149.410525.48-22.543825030803318210168.112728.48-22.5464280351004356254200.215731.88-22.5565350561255400279235186358-22.5614350961506444318269.721636.612-25.47174001202008559381330.227041.212-25.493050021225010622444387.432447.816-28.5101255033030012711521450.838150.816-32123160047235014762584514.44135420-32145060071540016864648571.547057.220-351645600920600LB连接尺寸公称通径(DN)600Lb凸面法兰（RF）主要尺（mm）重量(Kg)mminLDD1D2bn-φdHD0151/21659566.53514.54-162851007.8203/419011782.543164-1928512512.5251216124895117.54-1931316017.53211/422913398.563214-1932816023.54011/2241156114.37322.54-22.536518038.550229216512792338-19444200356521/2330190149.4105368-22.548325050803356210168.1127398-22.5533250601004432273216157458-25.46223501101255508330266.7186528-28.57503502001506559356292.12165512-28.58004502302008660419349.32706312-3292750041025010787508431.83247116-351257600625300128385594893817420-351468680860)
