产品概述:
电磁式燃气紧急切断阀是燃气管道的安全紧急切断装置。可与燃气泄漏报警系统连接或与消防及其它智能报警控制终端模块等连接,实现现场或远程自动/手动紧急切断气源,确保燃气管道运送及用气安全 。
产品符合 GB3836.1-2021《爆炸性环境 第1部分:设备通用要求》及GB3836.9-2021 《爆炸性环境 第9部分:由浇封型“m”保护的设备》和CJ /T 394-2018相关要求;本产品具有快速切断功能,密封性能好、耗电省、灵敏度高、动作可靠、使用方便等优点。开阀须人工手动开启,满足安全管理规范,符合事故处理特点。
产品特点:
※ 浇封防爆:防止火花产生,更加稳定可靠;
※ 开阀方式:手动复位,避免事故发生;
※ 保持方式:能在开阀与关阀状态下稳定工作即双稳态;
※ 关阀方式:断电自动关阀、外控信号自动手动关阀;
※ 关阀速度:1秒之内可切断气源;
※ 独立式泄压:在阀门前后压差过大情况下,打开泄压阀后可打开阀门,避免燃气排向大气消除安全隐患;
※ 零压差关阀:阀门可在前后压差为0情况下实现关阀动作,避免微泄漏时阀门不动作;
※ 密封形式:采用多级密封形式;
※ 密封特点:压力越大密封越紧,可保阀门多工况下稳定工作;
※ 动作可靠:可保持10年以上有效动作;
