一、电动蝶阀 产品概述
电动硬密封蝶阀被广泛用于石油、化工、电力、冶金、食品、医药、轻纺、造纸等行业,可安装在温度≤425℃,介质可为煤气、空气、蒸汽、水、海水、油品等工业管网上作调节流量和切断介质用。电动硬密封蝶阀配以电动执行气,可实现远距离控制和自动化操作。电动多层次金属密封蝶阀系列产品,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。
二、电动蝶阀 产品特点
由于电动硬密封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。
