埃(ai)美柯(ke)鑄鋼法(fa)蘭止回閥概述：

鑄鋼止(zhi)(zhi)(zhi)回(hui)閥(fa)(fa)(fa)：止(zhi)(zhi)(zhi)回(hui)閥(fa)(fa)(fa)又稱單(dan)向閥(fa)(fa)(fa)或逆止(zhi)(zhi)(zhi)閥(fa)(fa)(fa)，其作用(yong)是防止(zhi)(zhi)(zhi)管(guan)路中(zhong)的介質倒流。水(shui)泵吸水(shui)關(guan)的底閥(fa)(fa)(fa)也屬(shu)于(yu)止(zhi)(zhi)(zhi)回(hui)閥(fa)(fa)(fa)類。啟(qi)閉(bi)件靠介質流動和力量自(zi)行開啟(qi)或關(guan)閉(bi)，以防止(zhi)(zhi)(zhi)介質倒流的閥(fa)(fa)(fa)門叫(jiao)止(zhi)(zhi)(zhi)回(hui)閥(fa)(fa)(fa)。止(zhi)(zhi)(zhi)回(hui)閥(fa)(fa)(fa)屬(shu)于(yu)自(zi)動閥(fa)(fa)(fa)類，主要用(yong)于(yu)介質單(dan)向流動的管(guan)道上，只允許(xu)介質向一個方向流動，以防止(zhi)(zhi)(zhi)發(fa)生事(shi)故(gu)。

止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)按結構劃分(fen)，可分(fen)為升(sheng)降(jiang)式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)、旋(xuan)啟式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)和(he)(he)蝶式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)三種(zhong)。升(sheng)降(jiang)式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)可分(fen)為立式(shi)(shi)(shi)(shi)和(he)(he)臥式(shi)(shi)(shi)(shi)兩種(zhong)。旋(xuan)啟式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)分(fen)為單瓣式(shi)(shi)(shi)(shi)、雙(shuang)瓣式(shi)(shi)(shi)(shi)和(he)(he)多瓣式(shi)(shi)(shi)(shi)三種(zhong)。蝶式(shi)(shi)(shi)(shi)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)為直通式(shi)(shi)(shi)(shi)、以上幾種(zhong)止(zhi)(zhi)(zhi)回(hui)(hui)閥(fa)(fa)在連接(jie)形式(shi)(shi)(shi)(shi)上可分(fen)為螺紋連接(jie)、法(fa)蘭連接(jie)和(he)(he)焊接(jie)三種(zhong)。
