組合式(shi)三通(tong)(tong)(tong)閥(fa)(fa)(fa)(fa)(fa)主要用在(zai)(zai)焦爐(lu)氨(an)(an)水系統(tong)(tong)中(zhong)，在(zai)(zai)系統(tong)(tong)停車(che)，管路(lu)設(she)備檢修(xiu)時(shi)，將(jiang)(jiang)它關(guan)閉以截(jie)斷(duan)(duan)氨(an)(an)水介質(zhi)，而系統(tong)(tong)正常(chang)運行時(shi)，它始終處于全(quan)開(kai)(kai)啟狀態。其右側球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)接(jie)高(gao)壓(ya)(ya)系統(tong)(tong)，左側止(zhi)回(hui)閥(fa)(fa)(fa)(fa)(fa)接(jie)低(di)(di)(di)壓(ya)(ya)系統(tong)(tong)，中(zhong)間(jian)出(chu)(chu)口接(jie)排(pai)放管路(lu)，當(dang)球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)關(guan)閉時(shi)，高(gao)壓(ya)(ya)通(tong)(tong)(tong)道切斷(duan)(duan)，止(zhi)回(hui)閥(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)在(zai)(zai)低(di)(di)(di)壓(ya)(ya)介質(zhi)的推(tui)(tui)動(dong)下自(zi)動(dong)開(kai)(kai)啟，低(di)(di)(di)壓(ya)(ya)氨(an)(an)水由中(zhong)間(jian)出(chu)(chu)口通(tong)(tong)(tong)道排(pai)出(chu)(chu)。當(dang)球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)開(kai)(kai)啟時(shi)，高(gao)壓(ya)(ya)氨(an)(an)水將(jiang)(jiang)止(zhi)回(hui)閥(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)推(tui)(tui)向閥(fa)(fa)(fa)(fa)(fa)座(zuo)，止(zhi)回(hui)閥(fa)(fa)(fa)(fa)(fa)關(guan)閉，低(di)(di)(di)壓(ya)(ya)通(tong)(tong)(tong)道被切斷(duan)(duan)，高(gao)壓(ya)(ya)氨(an)(an)水由中(zhong)間(jian)出(chu)(chu)口通(tong)(tong)(tong)道排(pai)出(chu)(chu)，噴(pen)射完畢后(hou)，關(guan)閉球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)，止(zhi)回(hui)閥(fa)(fa)(fa)(fa)(fa)自(zi)動(dong)開(kai)(kai)啟，低(di)(di)(di)壓(ya)(ya)氨(an)(an)水又(you)能(neng)(neng)自(zi)動(dong)排(pai)放。由于該閥(fa)(fa)(fa)(fa)(fa)中(zhong)的直通(tong)(tong)(tong)式(shi)浮動(dong)球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)僅起高(gao)壓(ya)(ya)系統(tong)(tong)一側的開(kai)(kai)啟與關(guan)閉作用，而不(bu)是起三通(tong)(tong)(tong)轉換功能(neng)(neng)，因此(ci)，即使(shi)球(qiu)(qiu)體(ti)與閥(fa)(fa)(fa)(fa)(fa)座(zuo)在(zai)(zai)使(shi)用一段時(shi)間(jian)后(hou)裝配預緊(jin)力(li)消失，球(qiu)(qiu)體(ti)與閥(fa)(fa)(fa)(fa)(fa)座(zuo)之(zhi)間(jian)出(chu)(chu)現間(jian)隙，在(zai)(zai)球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)關(guan)閉時(shi)，高(gao)壓(ya)(ya)側介質(zhi)的壓(ya)(ya)力(li)仍能(neng)(neng)將(jiang)(jiang)球(qiu)(qiu)體(ti)推(tui)(tui)向出(chu)(chu)口側閥(fa)(fa)(fa)(fa)(fa)座(zuo)，使(shi)球(qiu)(qiu)體(ti)與出(chu)(chu)口側閥(fa)(fa)(fa)(fa)(fa)座(zuo)緊(jin)密接(jie)觸，從而閥(fa)(fa)(fa)(fa)(fa)門(men)仍具有很好的密封(feng)性能(neng)(neng)。本產品徹底解決了傳統(tong)(tong)的L型三通(tong)(tong)(tong)球(qiu)(qiu)閥(fa)(fa)(fa)(fa)(fa)容易密封(feng)失效的問題。
