自動(dòng)再循環(huán)閥對(duì)保護(hù)給水泵，避免水泵葉輪汽蝕損壞，保證整個(gè)機(jī)組正常運(yùn)行起到了至關(guān)重要的作用。由于鍋爐剛啟動(dòng)時(shí)流量小，壓差大，預(yù)期可能出現(xiàn)氣蝕和沖刷；隨著鍋爐的啟動(dòng)，流量隨之增大而壓差將逐漸變小，對(duì)閥門的流通能力要求極高；當(dāng)鍋爐恢復(fù)正常運(yùn)行時(shí)又必須具備快速關(guān)閉和緊急密封功能。因此自動(dòng)再循環(huán)閥必須具備以下特點(diǎn)方能勝任此惡劣工況：抗汽蝕，保護(hù)給水泵并提高給水泵效率；具備大流通能力，并能預(yù)防卡塞；具備V或VI級(jí)密封，快速開啟/關(guān)閉功能。金華自動(dòng)再循環(huán)閥怎么樣閥門類型主要依照旁路壓差確定，同時(shí)要核算主路壓降，因此需詳細(xì)核算旁路壓降。</p><div
