一、用途和特点该系列蝶阀式我公司工程技术人员研制开发的新一代高性能产品，其性能已处于国内外先进水平、广泛适用于低压、中压、高压、钢铁治金、石油、化工、电力等工业管道上作截断或调节介质流量用。该帆门采用三维偏心斜锥形阀座密封，蝶板密封采用新型金属片与弹性材料层叠而成，嵌装在蝶板上与阀座吻合。利用蝶板摆动压紧密封，所以密封面摩擦阻力小，关闭时具有越关越紧功能，这样密封性可靠，开启确保密封面完全脱离接触，保证了密封面不受损伤。该蝶阀结构特点排除了其他类型蝶阀开过位而不能密封的缺点，且在高曙下能正常使用，克服了其它类型阀门在高温使用时因热膨胀而容易泄漏的缺点。该蝶阀耕具使用介质要求，选用不同密封面材料，以保证密封面耐磨损、耐腐蚀、使用寿命长。 二、主要技术参数公称通经dn（in)2"-36"2"-36"公称压力pn(mpa)150lb300lb实验压力ps（mpa）强度试验3.07.5密封试验2.25.5适用介质水、蒸汽、油品、酸碱类、海水等适用温度-40～425℃ 三、主要零件材料名称材料阀体wcb、cfb、cf8m阀板wcb、cfb、cf8m帆杆304、316、1cr13密封套316、304填料柔性石墨、氟塑料四、主要连接尺寸型号英寸ll1dd1d2h2h1hmz-dwt/kgs毫米英寸毫米英寸毫米英寸毫米英寸毫米英寸毫米英寸毫米英寸毫米英寸对夹式法兰式d315w/f连接尺寸2"1.72434.251086.001524.75120.53.62924.3311011.0228013.58345m184-199203"1.93494.501147.501906.00152.55.001274.9212512.4031514.96380m184-1911294"2.20565.001279.002297.50190.56.191575.7014513.7835016.34415m208-1913335"2.50645.5014010.002548.502167.321866.5016515.3539017.91455m208-2216386"2.75705.5014011.002799.50241.58.502166.8917517.9145521.45545m208-2226748"2.80715.9015013.5034311.75298.510.622708.2621020.6725224.21615m248-22348610"3.00766.3016016.0040614.2536212.753249.8425023.8160527.36695m2412-255114212"3.38864.0017819.0048317.00298.515.0038111.2428528.7473032.78830m2712-257216714"3.63924.2019021.0053318.7536216.2541312.6032031.5080035.43900m2712-2910621816"4.001028.5021623.0059721.2543218.5047013.9835534.2584038.58980m3016-2913327518"4.501148.7422225.0063522.7547621.0053314.9638036.2292040.551030m3016-3217631520"5.001279.0022927.5039925.0054023.0058416.3441539.37100043.701110m3320-3219039524"6.0615410.5026732.0081329.5057827.2569218.7047545.51115551.371305m3320-3539458030"6.5016511.5029238.7598536.0063533.7585722.3858054.13137560.031525m3928-3547671732"7.5019012.5031841.75106038.50749.536.0091424.8063056.50143562.401585m3928-4161888036"8.0020313.0033046.00116842.7591440.25102226.7768062.40158569.481765m2032-417621042d330w/f连接尺寸6"2.75709.509783.502166.8917517.9143521.45545m208-22288"2.807111.75108510.622708.2621020.6752524.21615m248-223610"3.007614.2524012.753249.8425023.8160527.36695m2412-255312"3.388617.0029815.0038111.2428528.7473032.78830m2712-257414"3.639218.2536216.2541312.6432031.5080035.43900m2712-2911016"4.0010221.2543218.5047013.9835534.2587038.58980m3016-2913818"4.5011422.7547621.0053314.9638036.2292040.551030m3016-3218020"5.0012725.005403.0058416.3441539.37100043.701110m3320-3219624"6.0615429.50578277.2569218.7047545.51115651.371305m3320-3540030"6.5016536.0063533.7585722.3858054.13137560.031525m3928-3548236"8.0020342.7574940.25102226.7768062.40158569.481765m1832-42468d315l连接尺寸2"1.72434.251086.501655.009143.62924.3311011.0228013.58345m208-199203"2.50644.501148.262106.6310855.081274.9212512.4031514.96380m208-2212294"2.50645.0012710.002547.871276.181575.7014513.7835016.34415m208-2215355"2.75705.5014011.002799.251687.321866.3016515.3539017.91455m2012-2218406"3.00768.3021012.5031810.632008.502166.8917517.9145521.45545m2412-2628818"3.50899.0523015.0038113.0023510.622708.2621020.6752524.21615m2716-29379410"4.501149.8425017.5044515.2427012.753249.8425023.8160527.36695m3016-325615612"4.5011410.6227020.5052117.7633015.0038111.2428528.7473032.78830m3020-327918314"5.0012710.6227023.0058420.2438716.2641312.6032031.5080035.43900m3320-3511623916"5.5014012.2031025.5064812.5045118.5047013.9835534.2584038.58980m3324-3514630218"5.9815213.0033028.0071124.7251421.0053314.9638036.2292040.551030m3324-3519334620"5.9815213.8035030.5077527.0057123.0058416.3441539.37100043.701110m3324-4120943424"7.0017815.3539036.0091432.0062827.2469218.7047545.51115551.371305m3928-4943363830"9.0122917.7145043.00109239.2568627.6970322.3858054.13137560.031525m4532-53523114636"9.8824120.0751050.00127046.0081334.8888626.7768062.40158569.481765m5012-22838d330l连接尺寸6"3.007
