    <description><![CDATA[1.膨胀式密封系统
阀座的独特设计使得阀体和阀座有一个连续、可变形空腔。当阀板关闭后，阀座在外部气源的压力下，慢慢膨胀并抱紧阀板以达到密封的效果。需要开启时，空腔内的压力会快速排空让阀座收缩以释放阀板，然后再行打开阀板。因而，在启闭过程中，阀座和阀板的接触时间和接触面积都非常之少。

阀门的操作扭矩比传统蝶阀降低35%，阀板和阀座之间的磨损率减少了约90%，同时，阀门的密封可靠性得到了大幅提高。


2.集成化气动阀块
为膨胀密封蝶阀量身设计的一体化气控阀块确保高频次操作工况下的阀门开关的稳定性和****性。集成化的方案降低了内部管线的复杂性，也减小了整体的结构尺寸，从而简化了现场安装和维护。

    <title>D641W气动通风蝶阀</title>
    <link>http://www.shszfm.com/product/DF/8758.html</link>
    <description><![CDATA[<p ****='text-indent:2em;margin-bottom:20px;'>D641气动通风蝶阀采用与阀体相同材质做成的密封圈，阀门适用温度随阀体选材而定，一般在-29℃～425℃的区间范围内，公称压力≤0.6MPa，通径在50mm～1200mm之间，气动通风蝶阀一般适用于煤气、含尘气体、烟道气等管道作通风调节介质流量之用。气动通风蝶阀主要特点是设计新颖、合理、结构*特，重量轻，启闭迅速。操作力矩小，操作方便，灵活省力。阀门采用适宜的材料以满足低、中、高不同介质温度及腐蚀性介质管道的需要。</p>
