n产品概述:对夹式凸耳蝶阀的蝶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。凸耳对夹式蝶阀是用双头螺栓将阀门连接在两管道法兰之间,其结构简单、体积小、重量轻,只由少数几个零件组成。而且只需旋转90°即可快速启闭,操作简单,同时该阀门具有良好的流体控制特性。蝶阀处于完全开启位置时,蝶板厚度是介质流经阀体时WY的阻力,因此通过该阀门所产生的压力降很小,故具有较好的流量控制特性。蝶阀有弹密封和金属密封两种密封型式。弹性密封阀门,密封圈可以镶嵌在阀体上或附在蝶板周边。应用范围:蝶阀不仅在石油、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水系统。用于硫酸行业中气体管路:炉前鼓风机出入口,接力风机出入口,电除雾串联及联通阀,S02主鼓风机出入口,转化器调节,预热器出入口等调节和截止气量使用。用于硫磺制酸系统中的焚硫、转化、干吸工段,是硫磺制酸装置用阀的品Pai,被广大用户认为是:密封性能好,运转轻,副腐蚀,耐高温,操作方便、灵活、使用安全可靠的蝶阀,得到了大量推广使用。对夹式蝶阀还广泛用于:化工、石化、冶炼、医药、食品等行业中、蒸汽、空气、煤气、氨气、CO2气、油品、水、盐水、碱液、海水、硝酸、、硫酸、酸等介质的管路上作为调节和截流装置使用。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)。标准规范:设计制造标准:GB/T 12238-2008、ANSI B16.34、API609、MSS SP-68、JIS B2032、JIS B20结构长度标准:GB/T 12221-2005、API609、JIS B2002连接法兰标准:GB/T 9113、JB79、SH3406、HG20592、ASME B16.5、ASME B16.47、API605、JIS B2212压力温度等级:GB/T 12224-2005试验检验标准:GB/T 13927-2008、API598、JIS B2003技术参数:公称尺寸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℃零件材料与工况:名称材料阀体WCB、CFB、CF8M阀板WCB、CFB、CF8M阀杆304、316、1Cr13密封套316、304填料柔性石墨、塑料尺寸及重量: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"2.505.5014010.002548.502167.321866.5016515.3539017.91455M208-226"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"3.388.0017819.0048317.00298.515.0038111.2428528.7473032.78830M2712-2514"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"7.5019012.5031841.75106038.50749.536.0091424.8063056.50143562.401585M3928-41
