產品概述:
電磁式燃氣緊急切斷閥是燃氣管道的安全緊急切斷裝置。可與燃氣泄漏報警系統連接或與消防及其它智能報警控制終端模塊等連接,實現現場或遠程自動/手動緊急切斷氣源,確保燃氣管道運送及用氣安全 。
產品符合 GB3836.1-2021《爆炸性環境 第1部分:設備通用要求》及GB3836.9-2021 《爆炸性環境 第9部分:由澆封型“m”保護的設備》和CJ /T 394-2018相關要求;本產品具有快速切斷功能,密封性能好、耗電省、靈敏度高、動作可靠、使用方便等優點。開閥須人工手動開啟,滿足安全管理規范,符合事故處理特點。
產品特點:
※ 澆封防爆:防止火花產生,更加穩定可靠;
※ 開閥方式:手動復位,避免事故發生;
※ 保持方式:能在開閥與關閥狀態下穩定工作即雙穩態;
※ 關閥方式:斷電自動關閥、外控信號自動手動關閥;
※ 關閥速度:1秒之內可切斷氣源;
※ 獨立式泄壓:在閥門前后壓差過大情況下,打開泄壓閥后可打開閥門,避免燃氣排向大氣消除安全隱患;
※ 零壓差關閥:閥門可在前后壓差為0情況下實現關閥動作,避免微泄漏時閥門不動作;
※ 密封形式:采用多級密封形式;
※ 密封特點:壓力越大密封越緊,可保閥門多工況下穩定工作;
※ 動作可靠:可保持10年以上有效動作;
