主要技術(shù)尺寸
止回閥也稱逆止閥，是一種能自動阻止介質(zhì)倒流的閥門，通過介質(zhì)的作用力將閥瓣開啟，此時止回閥屬于打開狀態(tài)；通過止回閥進(jìn)出口壓力差、閥瓣自身重力等因素作用下啟閉件關(guān)閉，以防止介質(zhì)倒流。止回閥一般分為升降式、旋啟式、蝶式、隔膜式等幾種結(jié)構(gòu)類型。升降式止回閥的關(guān)閉件是沿閥座中心線移動；旋啟式止回閥的關(guān)閉件在閥體內(nèi)繞固定軸移動；蝶式止回閥的結(jié)構(gòu)類似蝶閥，結(jié)構(gòu)簡單、流阻小、水錘小；隔膜式止回閥采用隔膜作為關(guān)閉件，結(jié)構(gòu)簡單，水錘小，但受介質(zhì)壓力及溫度的限制。止回閥的功能是用來防止管路中的介質(zhì)倒流。止回閥屬于自動閥類，啟閉件靠流動介質(zhì)的力量自行開啟 或關(guān)閉。止回閥只用于介質(zhì)單向流動的管路上，阻止介質(zhì)回流，以防發(fā)生事故。適用介質(zhì)為：水、油品、蒸汽、酸性介質(zhì)等。
