自動再循環(huán)閥構(gòu)造簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。自動再循環(huán)閥處于完整開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時獨一的阻力，因而經(jīng)過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。自動再循環(huán)閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈能夠鑲嵌在閥體上或附在蝶板周邊。采用金屬密封的閥門普通比彈性密封的閥門壽命長，但很難做到完整密封。金屬密封能順應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺點。排空止回閥批發(fā)商</p></p><br
