產(chǎn)品詳情
電動(dòng)偏心半球閥特點(diǎn):
1、解決了工業(yè)生產(chǎn)中的漿狀、混流液體、灰塵等介質(zhì)在管道輸送中沉淀、易結(jié)垢、阻塞,使閥門關(guān)不嚴(yán)等問題。
2、開關(guān)輕便,開啟時(shí)球與殼體脫離,無(wú)任何接觸,啟動(dòng)扭矩小,轉(zhuǎn)動(dòng)靈活。關(guān)閉時(shí),半球與閥座的擠切作用能除去密封面上的污物,使閥門順利啟閉,安全系數(shù)高,密封性能好。
3、密封面的偏心結(jié)構(gòu),使球面能自動(dòng)補(bǔ)償磨損,能保持閥門的密封,使用壽命長(zhǎng)。
4、該閥門T型是屬于耐磨硬密封球閥,它的密封副材料是特殊的,密封面要經(jīng)過(guò)特殊耐磨處理。處理后表面達(dá)到HRC65-72度,故閥門的耐磨性能特別好。
5、閥門表面油漆,有常溫和高溫兩種。高溫用耐溫600℃的進(jìn)口漆,噴涂后,高溫使用不燒漆、炭化、焦化現(xiàn)象。不變色。
