产品工作原理和用途：美标凸耳式双向密封蝶阀板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°-90°之间，旋转到90°时，阀门则呈全开状态。不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用，而且还应用于热电站的冷却水系统。产品结构特点：①、三向偏心的独特设计使密封面之间无摩擦传动，延长了阀门使用寿命。②、由扭矩产生弹性密封。③、巧妙的楔形设计使阀门有越关越紧的自动密封功能，密封面之间具有补偿性、零泄漏。④、体积小、重量轻、操作轻巧、便于安装。⑤、可根据用户要求配置气动、电动装置，满足遥控和程控的需要。⑥、更换零件材质可适用于各种介质，并可进行衬里防腐(衬F46、GXPP、PO等)。产品性能参数：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℃产品主要零件材料：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、氟塑料产品主要尺寸：型号英寸LL1DD1D2H2H1HMZ-d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D315W/F连接尺寸2"1.72434.251086.001524.75120.53.62924.3311011.0228013.58345M184-193"1.93494.501147.501906.00152.55.001274.9212512.4031514.96380M184-194"2.20565.001279.002297.50190.56.191575.7014513.7835016.34415M208-195"2.50645.5014010.002548.502167.321866.5016515.3539017.91455M208-226"2.75705.5014011.002799.50241.58.502166.8917517.9145521.45545M208-228"2.80715.9015013.5034311.75298.510.622708.2621020.6725224.21615M248-2210"3.00766.3016016.0040614.2536212.753249.8425023.8160527.36695M2412-2512"3.38864.0017819.0048317.00298.515.0038111.2428528.7473032.78830M2712-2514"3.63924.2019021.0053318.7536216.2541312.6032031.5080035.43900M2712-2916"4.001028.5021623.0059721.2543218.5047013.9835534.2584038.58980M3016-2918"4.501148.7422225.0063522.7547621.0053314.9638036.2292040.551030M3016-3220"5.001279.0022927.5039925.0054023.0058416.3441539.37100043.701110M3320-3224"6.0615410.5026732.0081329.5057827.2569218.7047545.51115551.371305M3320-3530"6.5016511.5029238.7598536.0063533.7585722.3858054.13137560.031525M3928-3532"7.5019012.5031841.75106038.50749.536.0091424.8063056.50143562.401585M3928-4136"8.0020313.0033046.00116842.7591440.25102226.7768062.40158569.481765M2032-41D315L连接尺寸2"1.72434.251086.501655.009143.62924.3311011.0228013.58345M208-193"2.50644.501148.262106.6310855.081274.9212512.4031514.96380M208-224"2.50645.0012710.002547.871276.181575.7014513.7835016.34415M208-225"2.75705.5014011.002799.251687.321866.30165)
