止(zhi)回(hui)閥(Check Valve)：止(zhi)回(hui)閥又稱(cheng)單向閥或逆止(zhi)閥，其作用(yong)是防止(zhi)管路中(zhong)的介(jie)質倒流。水(shui)(shui)泵吸水(shui)(shui)關的底閥也屬于止(zhi)回(hui)閥類。
啟(qi)閉件靠介(jie)質(zhi)流(liu)動和力(li)量自(zi)行(xing)開啟(qi)或關(guan)閉，以防(fang)止(zhi)介(jie)質(zhi)倒流(liu)的(de)閥(fa)門叫止(zhi)回(hui)閥(fa)。止(zhi)回(hui)閥(fa)屬于(yu)自(zi)動閥(fa)類，主要(yao)用于(yu)介(jie)質(zhi)單向(xiang)流(liu)動的(de)管(guan)道(dao)上，只允許介(jie)質(zhi)向(xiang)一(yi)個方向(xiang)流(liu)動，以防(fang)止(zhi)發生事故(gu)。
止回閥(fa)(fa)按結構劃分，可分為升(sheng)降(jiang)式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)、旋啟式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)和蝶(die)式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)三(san)種(zhong)。升(sheng)降(jiang)式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)可分為立式(shi)(shi)(shi)(shi)(shi)和臥式(shi)(shi)(shi)(shi)(shi)兩(liang)種(zhong)。旋啟式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)分為單瓣(ban)(ban)式(shi)(shi)(shi)(shi)(shi)、雙瓣(ban)(ban)式(shi)(shi)(shi)(shi)(shi)和多瓣(ban)(ban)式(shi)(shi)(shi)(shi)(shi)三(san)種(zhong)。蝶(die)式(shi)(shi)(shi)(shi)(shi)止回閥(fa)(fa)為直通(tong)式(shi)(shi)(shi)(shi)(shi)、以(yi)上幾種(zhong)止回閥(fa)(fa)在(zai)連接形式(shi)(shi)(shi)(shi)(shi)上可分為螺(luo)紋連接、法蘭(lan)連接和焊(han)接三(san)種(zhong)。
止回閥(fa)的(de)(de)安(an)(an)裝(zhuang)應(ying)(ying)注意(yi)以下(xia)事(shi)頂：1、在管(guan)線(xian)中(zhong)不(bu)要(yao)使止回閥(fa)承受重量，大型的(de)(de)止回閥(fa)應(ying)(ying)獨立支(zhi)撐(cheng)，使之不(bu)受管(guan)系產生的(de)(de)壓力的(de)(de)影響。2、安(an)(an)裝(zhuang)時(shi)注意(yi)介質流動(dong)的(de)(de)方向應(ying)(ying)與閥(fa)體所票箭頭方向一致。3、升降(jiang)式垂直瓣止回閥(fa)應(ying)(ying)安(an)(an)裝(zhuang)在垂直管(guan)道上。4、升降(jiang)式水(shui)平(ping)瓣止回閥(fa)應(ying)(ying)安(an)(an)裝(zhuang)在水(shui)平(ping)管(guan)道上。
