产品简介

D673H气动弹性金属密封蝶阀采用一个“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。

因此被广泛地应用到介质温度≤550℃的冶金、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

产品特点

1、该蝶阀结构简单、紧凑、重量轻、易于安装和拆卸、维修方便；

2、本蝶阀采用不锈钢“U”型密封圈，具有一定的弹性无论在高温、低温的情况下，它与蝶板均具有优良的密封性；

3、本蝶阀的三维偏心距，经过严格的计算，“U”型密封圈与蝶板几乎无磨擦，使用寿命长，并具有越关越紧的功能；

4、蝶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；

5、本蝶阀结构独特，“开关”仅需转动阀杆90°即可完成。操作灵活、方便、省力、

不受介质压力的高低影响，密封性能可靠；

采用标准

设计标准 :GB/T12238-1989

法兰连接尺寸: GB/T9113.1-2000；GB/T9113.2-2000 GB/T9115.1-2000；GB/T9115.2-2000

结构长度:GB/T12221-1989

压力试验:GB/T13927-1992；JB/T9092-1999 执行机构

采用新型系列GT型气动执行器，有双作用式和单作用式（弹簧复位），齿轮传动，安全可靠；

大口径阀门采用系列AW型气动执行器拔叉式传动，结构合理，输出扭矩大，有双作用式和单作用式

1、齿轮式双活塞，输出力矩大，体积小。

2、气缸选用铝金材料，重量轻、外形美观。

3、可在顶部、底部安装手动操作机构。

4、齿条式连接可调节开启角度、额定流量。

5、执行器可选带电讯号反馈指示及各类附件以实现自动化操作。

6、IS05211标准连接为产品的安装更换提供了方便。

7、两端调的节螺钉可使标准产品在0°和90°有±4°的可调范围。确保与阀门的同步精度。
