Product Name:
D943H electric multi-level hard-seal butterfly valve
Description:

电动多层次硬密封蝶阀  D943H

D943H电动多层次硬密封法兰式蝶阀系列产品,系长寿命、节能型蝶阀。其结构采用三维编心原理设计,阀座采用硬软密封兼容的多层次结构,加工精湛,工艺先进。本产品由阀体、蝶板、多层次阀座、阀杆、传动机构等主要部件组成。因此被广泛地应用到冶金、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。

特点


由于本产品蝶阀采用的是三维偏心原理设计,使密封面的空间运动轨迹达到理想化,密封面相互之间无磨擦、无干涉、加之密封材料选择得当,从而使蝶阀的密封性、耐腐蚀性、耐高温性和耐磨性等得到了可靠的保证。其主要特点如下:

1、开启力矩小,灵活方便,省力节能。
2、三维编心结构,使蝶板越关越紧,其密封性能可靠,达到无泄漏。
3、耐高压、耐腐蚀、耐磨损、使用寿命长等。
