中文說(shuō)明書(shū)
產(chǎn)品簡(jiǎn)介
SZ品牌液氨緊急切斷閥是專(zhuān)為液氨等腐蝕性介質(zhì)設計的自動(dòng)化安全裝置，能夠在緊急情況下迅速切斷流體通道，防止事故擴大，確保生產(chǎn)安全。本產(chǎn)品采用高品質(zhì)不銹鋼材料制成，具有良好的耐腐蝕性和密封性能，適用于高壓、低溫及含腐蝕性氣體的環(huán)境。
技術(shù)特點(diǎn)
? 高可靠性： 采用精密的電氣控制系統，確保切斷動(dòng)作迅速準確，無(wú)泄漏風(fēng)險。
? 耐腐蝕材料： 閥體、閥座及密封件均選用耐腐蝕合金材料，適應液氨等介質(zhì)的嚴苛環(huán)境。
? 多重保護： 配備手動(dòng)復位裝置及故障報警系統，便于日常維護與緊急處理。
? 智能化控制： 可與DCS、PLC等自動(dòng)化系統集成，實(shí)現遠程監控與自動(dòng)控制。
? 緊急切斷功能： 一旦接收到緊急信號或觸發(fā)預設條件，立即切斷液氨流動(dòng)，防止事故蔓延。
安裝與操作
1. 安裝前準備： 檢查閥門(mén)型號、規格是否符合設計要求，清理管道內的雜物。
2. 安裝位置： 應安裝在液氨管線(xiàn)的關(guān)鍵位置，便于快速切斷流體。
3. 電氣連接： 按照電氣圖紙連接控制器與電源、信號線(xiàn)，確保連接可靠。
4. 測試與調試： 安裝完成后進(jìn)行功能測試，確保切斷閥在接收到信號后能迅速響應并切斷流體。
5. 日常維護： 定期檢查閥門(mén)密封性、電氣控制系統及報警系統是否正常工作。
注意事項
? 嚴禁在閥門(mén)未完全關(guān)閉的情況下進(jìn)行拆卸或維修。
? 定期檢查電氣控制線(xiàn)路，避免老化、破損導致故障。
? 嚴禁使用非原裝配件替換閥門(mén)關(guān)鍵部件。
? 在操作過(guò)程中，應佩戴防護裝備，避免液氨直接接觸皮膚或眼睛。
