一、緊急關閉閥產品概述：
900X緊急關閉閥(fa)(fa)是一種用(yong)(yong)(yong)(yong)于消防用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)與生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)并聯的(de)(de)供(gong)水(shui)(shui)(shui)系統中，用(yong)(yong)(yong)(yong)來調(diao)配供(gong)水(shui)(shui)(shui)方(fang)向(xiang)的(de)(de)閥(fa)(fa)門(men)(men)。當火災發生時(shi)，消防急需大(da)量用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)，立即切斷生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)，確保足夠(gou)的(de)(de)消防用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)；當消防停止用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)壓力減小時(shi)，閥(fa)(fa)門(men)(men)自動打開，呈常(chang)開狀態，恢復(fu)生活供(gong)水(shui)(shui)(shui)。該閥(fa)(fa)使系統無須(xu)另(ling)設(she)專門(men)(men)的(de)(de)消防單獨(du)供(gong)水(shui)(shui)(shui)管網(wang)，大(da)大(da)地節約了建設(she)成本和用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)量。閥(fa)(fa)門(men)(men)控(kong)制靈敏度高，安全可靠，調(diao)試簡(jian)便，使用(yong)(yong)(yong)(yong)壽(shou)命長。
二、緊急關閉閥作用用途：
該閥適用于生(sheng)(sheng)活(huo)(huo)小區中消防(fang)(fang)用于水(shui)(shui)(shui)與生(sheng)(sheng)活(huo)(huo)用水(shui)(shui)(shui)并(bing)聯的供(gong)水(shui)(shui)(shui)系(xi)統中。當消防(fang)(fang)用水(shui)(shui)(shui)時，閥門自動(dong)緊(jin)急關(guan)閉，切斷生(sheng)(sheng)活(huo)(huo)用水(shui)(shui)(shui)保證消防(fang)(fang)用水(shui)(shui)(shui)。當消防(fang)(fang)結束(shu)時，閥門自動(dong)打開，恢復生(sheng)(sheng)活(huo)(huo)供(gong)水(shui)(shui)(shui)比傳統的消防(fang)(fang)單(dan)獨供(gong)水(shui)(shui)(shui)更(geng)能節約成本(ben)。
