产品详细介绍：

2 双偏心双向金属密封蝶阀
      用途：
       双偏心双向密封系列蝶阀是我公司应广大用户要求，精心研究设计的新一代产品。该系列蝶阀引进国内外先进制造技术，以独特新颖的结构，获得高品质的性能。该阀结构合理，密封性能可靠、流阻小、压差低、驱动灵活省力，使用寿命倍增。符合GB12238-89《法兰和对夹连接蝶阀》和JB/T8527-1997《金属密封蝶阀》标准，并参照美国ANSI/AWWAC504标准，采用美国CAD辅助软件设计。双偏心，即轴向偏心，阀轴中心线不在阀板密封面上；径向偏心：阀轴的中心不在阀门通道的中心上，阀板采用双平板桁架式多流道结构，在流速较高时，各流道水流能够互相制衡，避免阀板出现颤抖现象，确保阀门稳定性。特殊的设计，特殊的几何结构，使阀门具有越关越紧得功能，当打开阀门时，只要阀轴稍微旋转，阀板即全部脱离阀座，减少了摩擦力，是开启力矩呈现最小最佳状态，密封严实可靠，经久耐用，广泛的用于水利功能、自来水、电力循环水、石油、石化等工业管道上作截断介质流动。
      Double biased bidirectionla pressure metal seal series butterfly valve is the our company should the user communities request,carefully studies the design the new generation of product.This serids butterfly valve has introduced the domestic and foreign advanced manufactures technology,by the unique novel structure,obtains the high quality the performance.This valve stucture teasonable,the seal strict relable,resistance small,the differential pressure is low,the actuation nimbly reduces effort,the service life multipies,Conforms to GB12238-89”Flange And to Clamps Connects Reed balbe”and JB/t8527-1997”Metal seal butterfly valve” the standard,and refers to the American ANSI/AWWWAC504 standard,uses the American CAD software assistance design.Double bias ,namely axial bias, valve axle not in valve board packing surface;Radial direction bias:The valve axle in the valve passage center core,the valve board does not use the plate posture multi-flow channels structure,is higher when the speed of flow,various flow chanels current of water can mutually make the graduated arm,avoids the valve board appearing shivers the phenomenon,guarantees the valve the stability.The special design,the special geometry structure,enable the valve board to habe pass tighter function,when turns on the valve,so long as the valve shaft slightly revolves,the valve board namely completely is separated form the valve seat,reduced the friction force causes to open the moment of force to present the smallest optimum condition,the seal solid is reliable, durable,the widespread application to industry pipeline and so hydraulic engineering,running water,electric power circulating water,petroleum,chemical industry makes the interruption to flow.
       特点 Features：
1、    蝶阀为双向承压，双向金属密封，特殊的结构形式可任意调整密封比压，采用偏心S形锥形阀座密封面，使密封面不易损坏，提高阀门的使用寿命。
2、    操作扭转力矩小，转90度启闭，轻便迅速。
3、    流阻小，具有良好的水利特性，流量特性近试倾斜直线，节能效果好，双向密封对水流无要求。
4、    阀板采用符合流体学性能的双平板桁架式多流道设计。
