結構原理:

空氣泡沫產生器主要由殼體組、泡沫(mò)噴管組和導板組三個部份構成。

當(dāng)泡沫混(hún)合液(yè)流過產生器噴嘴時,形成擴(kuò)散的霧化射流,在其周圍產生負(fù)壓,從而吸入大量空氣形(xíng)成(chéng)空氣泡沫,空氣泡沫通過泡(pào)沫噴管和導(dǎo)板輸入貯罐內,沿罐壁淌下,平穩地覆蓋在燃燒液麵上。

當需要在水平管道中使用波紋管截止閥電動截止閥是一種比較新型(xíng)的截止閥類別,它有著自身結構(gòu)所獨有的一些優越性,如開關無摩擦(cā),密封(fēng)不易磨損,啟閉力矩小(xiǎo)。這樣可減小所配(pèi)執行器的規格。

配以多回轉電動執行機構,可實現對介質的調節和(hé)嚴密切斷(duàn)。廣泛適用(yòng)於石油(yóu)、化工、城市給排水等要求嚴(yán)格切斷的工況,必須保(bǎo)證按照波紋管截止閥生產廠家規定的角度在水平管...
