• 多重保護： 配備手(shǒu)動(dòng)復(fù)位(wèi)裝置及(jí)故(gù)障報(bào)警係統，便(biàn)於(yú)日(rì)常維(wéi)護(hù)與(yǔ)緊急處(chǔ)理(lǐ)。
• 智能(néng)化控製： 可(kě)與DCS，PLC等自動(dòng)化(huà)係統集成(chéng)，實(shí)現遠(yuǎn)程(chéng)監控與自動控製。
• 緊急切(qiē)斷功能： 一旦接收到緊急(jí)信號或觸(chù)發預設條件(jiàn)，立(lì)即切斷(duàn)液氨(ān)流動，防止事故(gù)蔓(màn)延(yán)。
安(ān)裝(zhuāng)與(yǔ)操作
1. 安裝前準(zhǔn)備： 檢查(chá)閥(fá)門(mén)型號，規(guī)格是否符(fú)合設計(jì)要求，清理(lǐ)管道(dào)內的雜物。
2. 安裝位(wèi)置： 應(yīng)安裝在液氨(ān)管綫的關(guān)鍵位(wèi)置，便(biàn)於快(kuài)速切(qiē)斷(duàn)流體(tǐ)。
3. 電氣連接： 按照電氣圖紙(zhǐ)連(lián)接控製器(qì)與電源，信號綫，確保(bǎo)連接(jiē)可(kě)靠(kào)。
4. 測(cè)試(shì)與(yǔ)調(tiáo)試： 安(ān)裝(zhuāng)完成(chéng)後進行功能(néng)測(cè)試(shì)，確(què)保切斷(duàn)閥(fá)在(zài)接收到(dào)信(xìn)號後能迅速(sù)響應並切(qiē)斷流(liú)體。
5. 日常(cháng)維(wéi)護(hù)： 定期(qī)檢查閥(fá)門密封(fēng)性，電氣(qì)控製係(xì)統及報警係(xì)統(tǒng)是(shì)否(fǒu)正常工作。
注意(yì)事項
• 嚴(yán)禁在(zài)閥門未完(wán)全(quán)關閉的(dí)情況(kuàng)下進行拆卸(xiè)或維修(xiū)。
