DT673H-6,DT673H-10,DT673H-16,DT973H-6,DT973H-10,DT373H-16,气动对夹式弹性硬密封蝶阀

概述
DT673气动对夹式弹性硬密封蝶阀可用于现场要求空间比较窄、管道距离较短的场合。气动对夹蝶阀采用一个“U”型不锈钢密封圈，该精密的弹性密封圈与经过抛光的蝶板三维偏心接触，解决了传统偏心蝶阀在启闭0°～10°瞬间密封面仍处于滑动接触摩擦的弊病,实现蝶板在开启瞬间密封面即分离,关闭接触即密封的效果,达到延长使用寿命、密封性能最佳的目的。气动对夹蝶阀广泛地应用到冶金、电力、石油、化工、空气、煤气、可燃气体以及给排水等腐蚀性介质的管道上，是调节流量和截断流体的最佳装置。
特点
气动对夹蝶阀采用三偏心密封结构，阀座与蝶板几乎无磨损，具有越观越紧的密封功能。
密封圈选用不锈钢制作，具有金属硬密封和弹性密封的双重优点，无论在低温和高温的情况下，均具有优良的密封性能,具有耐腐蚀,使用寿命长等特点。
碟板密封面采用堆焊钴基硬质合金，密封面耐磨损，使用寿命长。
大规格蝶板采用绗架结构，强度高，过流面积大，流阻小。
本阀具有双向密封功能，安装时不受介质流向的限制，也不受空间位置的影响，可在任何方向安装。
驱动装置可以多工位（旋转90°或180°）安装，便于用户使用。
