【電動閥門】電動襯氟蝶閥與電動硬密封蝶閥的區別

發布日期:[2020-11-02]     點擊率:

電動蝶閥是近幾年來工業管道中最常用的閥門之一,除了普通的開啟關閉之外,也能用于調節控制各種水、液體、氣體等流體的壓力、流量、溫度等參數,是工業自動化控制領域中的重要執行單元,被廣泛應用于化工、電力、石油、冶金、蒸汽、環保、消防系統等場合!并且電動蝶閥的種類較多,控制形式多變,可滿足各種不同的工況要求!



電動襯氟蝶閥和電動硬密封蝶閥作為蝶閥中最為常用的兩個種類,被適用的介質及壓力溫度完全是不一樣的!但很多人在兩者之間的選用,常常顯得有些捉拿不定!最簡單來說,兩者的控制形式是一樣的,不同的是密封結構形式,電動襯氟蝶閥適合用于含有腐蝕性介質,但只能常溫常壓,電動硬密封蝶閥則可用于各種壓力溫度范圍!詳細區別如下:



1、從結構上:硬密封蝶閥指的是密封副的兩側均是金屬材料或較硬的其它材料。而軟密封蝶閥則是接觸的兩密封面可以單獨,也可以全部使用軟質材料,如襯氟蝶閥即為蝶板和閥座均用四氟包裹;

2、從密封性能上:軟密封襯氟蝶閥的優點是密封性能好,缺點是容易老化、磨損、使用壽命短。硬密封蝶閥的使用壽命長,但是密封性相對比軟密封差。

3、從使用條件上:軟密封襯氟蝶閥用于常溫常壓環境,硬密封蝶閥可用于低溫、常溫、高溫等環境,一般可以做較高的壓力,軟密封則不行,但襯氟蝶閥具有超強的耐腐蝕性能!

4、從制造上:至于制造方面,從原理上來看,兩者差別不大,主要就是閥座的區別,軟密封襯氟蝶閥是非金屬結構,硬密封蝶閥是金屬結構,要考慮到金屬之間的硬度關系,以及工況,走的什么介質等方面。
