高性能蝶阀概述

高性能蝶阀概述：高性能蝶阀该产品广泛用于石油、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。

驱动形式有手动、蜗轮传动、气动、液动、电动、电液联动等执行机构，可实现远距离控制和自动化操作。金属硬密封蝶阀系列产品，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。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。
