中文說明書
產(chǎn)品簡(jiǎn)介
SZ品牌液氨緊急切斷閥是專為液氨等腐蝕性介質(zhì)設(shè)計(jì)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(kuò)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(tǒng)，確保切斷動(dòng)作迅速準(zhǔn)確，無泄漏風(fēng)險(xiǎn)。
? 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(yīng)液氨等介質(zhì)的嚴(yán)苛環(huán)境。
? 多重保護(hù)： 配備手動(dòng)復(fù)位裝置及故障報(bào)警系統(tǒng)，便于日常維護(hù)與緊急處理。
? 智能化控制： 可與DCS、PLC等自動(dòng)化系統(tǒng)集成，實(shí)現(xiàn)遠(yuǎn)程監(jiān)控與自動(dòng)控制。
? 緊急切斷功能： 一旦接收到緊急信號(hào)或觸發(fā)預(yù)設(shè)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(zhǔn)備： 檢查閥門型號(hào)、規(guī)格是否符合設(shè)計(jì)要求，清理管道內(nèi)的雜物。
2. 安裝位置： 應(yīng)安裝在液氨管線的關(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(hào)線，確保連接可靠。
4. 測(cè)試與調(diào)試： 安裝完成后進(jìn)行功能測(cè)試，確保切斷閥在接收到信號(hào)后能迅速響應(yīng)并切斷流體。
5. 日常維護(hù)： 定期檢查閥門密封性、電氣控制系統(tǒng)及報(bào)警系統(tǒng)是否正常工作。
注意事項(xiàng)
? 嚴(yán)禁在閥門未完全關(guān)閉的情況下進(jìn)行拆卸或維修。
? 定期檢查電氣控制線路，避免老化、破損導(dǎo)致故障。
? 嚴(yán)禁使用非原裝配件替換閥門關(guān)鍵部件。
? 在操作過程中，應(yīng)佩戴防護(hù)裝備，避免液氨直接接觸皮膚或眼睛。
English Specification Sheet
Product Introduction
Product Name: SZ Brand Liquid Ammonia Emergency Shutdown Valve
Manufacturer: Shanghai Shangzhao Valve Co., Ltd.
Product Number: 0QDQ421F-25C
Application Fields: Emergency safety control of liquid ammonia pipelines in chemical, petroleum, refrigeration, food processing, and other industries.
Technical Features
? High Reliability: Equipped with a precise electrical control system, ensuring rapid and accurate shut-off action with no leakage risks.
? Corrosion-Resistant Materials: The valve body, seat, and seals are all made of corrosion-resistant alloys, suitable for harsh environments with high pressure, low temperatures, and corrosive gases.
? Multiple Protection Mechanisms: Comes with manual reset devices and fault alarm systems for ease of maintenance and emergency response.
? Intelligent Control: Can be integrated with DCS, PLC, and other automation systems for remote monitoring and automatic control.
? Emergency Shutdown Function: Immediately shuts off the flow of liquid ammonia upon receiving an emergency signal or triggering preset conditions, preventing accident escalation.
Installation & Operation
1. Pre-Installation Preparation: Verify that the valve model and specifications meet design requirements, and clean the pipeline of debris.
2. Installation Location: Install at a strategic point on the liquid ammonia pipeline for quick fluid cutoff.
3. Electrical Connection: Connect the controller to power sources and signal lines according to the electrical schematics, ensuring reliable connections.
4. Testing & Commissioning: Perform functional tests after installation to ensure the valve responds promptly and cuts off the fluid upon receiving a signal.
5. Routine Maintenance: Regularly check the valve's sealing performance, electrical control system, and alarm system for proper functioning.
Precautions
? Do not dismantle or repair the valve while it is not fully closed.
? Regularly inspect electrical control wiring to avoid faults caused by aging or damage.
? Never use non-original spare parts to replace critical components of the valve.
? Wear protective gear during operation to prevent direct contact of liquid ammonia with skin or eyes.
