PH44H排渣(zha)止回閥(fa)
排渣止回閥(check valve):止回閥又稱單向閥或逆止閥,其作用是防止管路中的介質倒流。水泵吸水關的底閥也屬于止回閥類。
啟閉件靠(kao)介(jie)質(zhi)(zhi)(zhi)流(liu)動和(he)(he)力(li)(li)量自(zi)行開啟或關閉,以防止(zhi)介(jie)質(zhi)(zhi)(zhi)倒(dao)流(liu)的(de)閥(fa)(fa)(fa)(fa)門叫(jiao)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)。止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)屬于自(zi)動閥(fa)(fa)(fa)(fa)類(lei),主要用(yong)(yong)于介(jie)質(zhi)(zhi)(zhi)單(dan)向(xiang)流(liu)動的(de)管道上,只允許介(jie)質(zhi)(zhi)(zhi)向(xiang)一(yi)個方(fang)向(xiang)流(liu)動,以防止(zhi)發生事故。 止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)按結構劃分(fen),可(ke)(ke)分(fen)為升降式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)、旋啟式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)和(he)(he)蝶式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)三(san)(san)種(zhong)(zhong)。升降式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)可(ke)(ke)分(fen)為立式(shi)(shi)(shi)(shi)和(he)(he)臥(wo)式(shi)(shi)(shi)(shi)兩種(zhong)(zhong)。旋啟式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)分(fen)為單(dan)瓣(ban)式(shi)(shi)(shi)(shi)、雙(shuang)瓣(ban)式(shi)(shi)(shi)(shi)和(he)(he)多瓣(ban)式(shi)(shi)(shi)(shi)三(san)(san)種(zhong)(zhong)。蝶式(shi)(shi)(shi)(shi)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)為直通式(shi)(shi)(shi)(shi)、以上幾(ji)種(zhong)(zhong)止(zhi)回(hui)(hui)閥(fa)(fa)(fa)(fa)在連(lian)(lian)接形式(shi)(shi)(shi)(shi)上可(ke)(ke)分(fen)為螺紋(wen)連(lian)(lian)接、法(fa)蘭連(lian)(lian)接和(he)(he)焊(han)接三(san)(san)種(zhong)(zhong)。 主要適用(yong)(yong)于不超過6.4MPa、工作溫度≤200℃的(de)礦山、冶金、電力(li)(li)、化(hua)工、污水排放等行業(ye)輸送礦漿、砂漿、污水。
