电动偏心半球阀特点:
1、解决了工业生产中的浆状、混流液体、灰尘等介质在管道输送中沉淀、易结垢、阻塞,使阀门关不严等问题。
2、开关轻便,开启时球与壳体脱离,无任何接触,启动扭矩小,转动灵活。关闭时,半球与阀座的挤切作用能除去密封面上的污物,使阀门顺利启闭,安全系数高,密封性能好。
3、密封面的偏心结构,使球面能自动补偿磨损,能保持阀门的密封,使用寿命长。
4、该阀门T型是属于耐磨硬密封球阀,它的密封副材料是特殊的,密封面要经过特殊耐磨处理。处理后表面达到HRC65-72度,故阀门的耐磨性能特别好。
5、阀门表面油漆,有常温和高温两种。高温用耐温600℃的进口漆,喷涂后,高温使用不烧漆、炭化、焦化现象。不变色。
