旋(xuan)啟(qi)(qi)(qi)式止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)的閥(fa)(fa)(fa)瓣(ban)(ban)繞轉(zhuan)軸做旋(xuan)轉(zhuan)運(yun)動。其流體阻(zu)力一(yi)(yi)般(ban)小(xiao)于(yu)(yu)(yu)升降式止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)，它(ta)適(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)較大(da)口徑(jing)的場合。根據閥(fa)(fa)(fa)瓣(ban)(ban)的數目可(ke)分(fen)為單瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式、雙(shuang)(shuang)瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式及(ji)多瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式三(san)種。單瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)一(yi)(yi)般(ban)適(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)中(zhong)等口徑(jing)場合。大(da)口徑(jing)管路(lu)選(xuan)用(yong)(yong)(yong)單瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)時，為減少水(shui)錘(chui)壓(ya)力，最(zui)好采用(yong)(yong)(yong)能減小(xiao)水(shui)錘(chui)壓(ya)力的緩閉止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)閥(fa)(fa)(fa)門。雙(shuang)(shuang)瓣(ban)(ban)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)適(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)大(da)中(zhong)口徑(jing)管路(lu)。對夾(jia)雙(shuang)(shuang)瓣(ban)(ban)旋(xuan)啟(qi)(qi)(qi)式止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)結構小(xiao)、重量輕，是一(yi)(yi)種發展較快的止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)；多瓣(ban)(ban)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)適(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)大(da)口徑(jing)管路(lu)。
