氣動薄膜調節(jiē)閥選型中不同流體介質的材質選用表

氣動薄膜調節(jiē)閥選(xuǎn)型中不同流(liú)體介(jiè)質的材質選用表
        本閥門材質選用表是用來大致指(zhǐ)出與某種(zhǒng)流體介質接觸而發生(shēng)反應時,應如何選擇適當的材料。表中(zhōng)的推薦不是絕對的,因為碳鋼,鑄鐵,不鏽鋼(gāng),青銅,蒙乃爾合金,哈氏(shì)合金,鈦,鈷鉻合金,沉(chén)澱鋼等閥門材料的耐腐蝕性與流(liú)體的濃度、溫度、壓力和雜質等因素有(yǒu)關。因此,必須強調本(běn)表(biǎo)隻能作為一個導則(zé)參(cān)考。

符號:
A - 能夠或正被成功應用       B - 應用過程應注意        C - 不能應用       LL - 缺乏資料
