產(chǎn)品概述:
電磁式燃?xì)饩o急切斷閥是燃?xì)夤艿赖陌踩o急切斷裝置??膳c燃?xì)庑孤﹫?bào)警系統(tǒng)連接或與消防及其它智能報(bào)警控制終端模塊等連接,實(shí)現(xiàn)現(xiàn)場或遠(yuǎn)程自動/手動緊急切斷氣源,確保燃?xì)夤艿肋\(yùn)送及用氣安全 。
產(chǎn)品符合 GB3836.1-2021《爆炸性環(huán)境 第1部分:設(shè)備通用要求》及GB3836.9-2021 《爆炸性環(huán)境 第9部分:由澆封型“m”保護(hù)的設(shè)備》和CJ /T 394-2018相關(guān)要求;本產(chǎn)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(yōu)點(diǎn)。開閥須人工手動開啟,滿足安全管理規(guī)范,符合事故處理特點(diǎn)。
產(chǎn)品特點(diǎn):
※ 澆封防爆:防止火花產(chǎn)生,更加穩(wěn)定可靠;
※ 開閥方式:手動復(fù)位,避免事故發(fā)生;
※ 保持方式:能在開閥與關(guān)閥狀態(tài)下穩(wěn)定工作即雙穩(wěn)態(tài);
※ 關(guān)閥方式:斷電自動關(guān)閥、外控信號自動手動關(guān)閥;
※ 關(guān)閥速度:1秒之內(nèi)可切斷氣源;
※ 獨(dú)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?xì)馀畔虼髿庀踩[患;
※ 零壓差關(guān)閥:閥門可在前后壓差為0情況下實(shí)現(xiàn)關(guān)閥動作,避免微泄漏時(shí)閥門不動作;
※ 密封形式:采用多級密封形式;
※ 密封特點(diǎn):壓力越大密封越緊,可保閥門多工況下穩(wěn)定工作;
※ 動作可靠:可保持10年以上有效動作;
