900X緊急關(guān)閉閥產(chǎn)品簡介
900X緊急關(guān)閉閥，是一種用于消防用水與生活用水并聯(lián)的供水系統(tǒng)中，用來調(diào)配水方向的閥門，當火災(zāi)發(fā)生時，消防急需大量用水，900X緊急關(guān)閉閥立即切斷生活用水，確保主夠的消防用水，當消防停止用水，壓力減小時，閥門自動打開，呈現(xiàn)常開狀態(tài)，恢復生活供水。該閥使系統(tǒng)無需另設(shè)專門的消防單獨供水管網(wǎng)，大大節(jié)約了建設(shè)成本和用水量。閥門控制靈敏度高，安全可靠，調(diào)試簡便，使用壽命長。
900X緊急關(guān)閉閥工作原理
當主閥出口壓力低于導閥設(shè)定的壓力時，導閥此時處于開通狀態(tài)，主閥上腔壓力與主閥出口壓力相等，進口與吃口存在壓差，水流經(jīng)閥口出口流出，當消防泵氣泵時，或變平泵壓力升高時，超過導閥設(shè)定壓力，由主閥進口向?qū)чy管控制室壓力升高，作用在彈簧壓力增大，向下壓緊，帶動閥芯下移，使導閥關(guān)閉，此時主閥進口壓力通過節(jié)流閥補充到主閥閥蓋上腔，因閥瓣受到向下壓力大于向上推力，主閥關(guān)閉
值得注意的是，進口壓力小于設(shè)定壓力是，主閥處于開啟狀態(tài)，進口壓力大于設(shè)定壓力，閥瓣關(guān)閉。
