品牌：RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口燃?xì)饩o急切斷電磁閥在日常工作中處于常開(kāi)狀態(tài)，電磁閥線(xiàn)圈處于斷電狀態(tài)，不消耗電能 The gas emergency shut-off solenoid valve is in a normally open state in daily work, and the solenoid valve coil is in a power off state, without consuming electrical energy
當(dāng)事故發(fā)生時(shí)，系統(tǒng)發(fā)出型號(hào)，閥門(mén)線(xiàn)圈瞬時(shí)通電，觸發(fā)閥門(mén)快速關(guān)閉，并進(jìn)入自鎖狀態(tài) When an accident occurs, the system issues a model number, and the valve coil is momentarily energized, triggering the valve to quickly close and enter a self-locking state
當(dāng)工作人員處理完事故，人工重新開(kāi)啟閥門(mén)，才會(huì)恢復(fù)供氣 Only when the staff have handled the accident and manually reopened the valve can gas supply be restored
閥門(mén)采用先導(dǎo)式閥瓣，開(kāi)啟輕松，即使壓力達(dá)到6Bar開(kāi)啟也十分輕松，口徑大于DN125，采用杠桿手柄，使閥門(mén)達(dá)到開(kāi)關(guān)省力、快捷 The valve adopts a pilot operated disc, making it easy to open even when the pressure reaches 6Bar. The diameter is larger than DN125, and a lever handle is used to make the valve labor-saving and fast to open and close
根據(jù)客戶(hù)要求也可提供斷電關(guān)閉的常閉型緊急切斷閥 According to customer requirements, a normally closed emergency shut-off valve can also be provided for power-off closure
進(jìn)口燃?xì)饩o急切斷電磁閥控制原理--Control principle of imported gas emergency shut-off solenoid valve
常開(kāi)--閥關(guān)閉后在通電或斷電都不會(huì)自動(dòng)開(kāi)啟，需手動(dòng)拉開(kāi)，保持打開(kāi)狀態(tài)，節(jié)能、 Normally open - After the valve is closed, it will not automatically open when powered on or off. It needs to be manually opened and kept open, which is energy-saving and safe
1.閥需要打開(kāi)時(shí)，旋下防護(hù)罩，用力拉手柄，閥打開(kāi) When the valve needs to be opened, unscrew the protective cover and forcefully pull the handle to open the valve
2.閥需要關(guān)閉時(shí)，線(xiàn)圈通電不超過(guò)30秒鐘，閥迅速關(guān)閉 When the valve needs to be closed, the coil is energized for no more than 30 seconds and the valve quickly closes
手動(dòng)復(fù)位操作過(guò)程-- Manual reset operation process
當(dāng)閥門(mén)被切斷，管道漏氣故障排出后，工作人員需要手動(dòng)復(fù)位時(shí)，用力向上提拉手動(dòng)復(fù)位桿，聽(tīng)到“咔”的一聲，說(shuō)明閥門(mén)完全被打開(kāi)，此時(shí)，即使松開(kāi)手，也不會(huì)被切斷。（除非再給閥門(mén)線(xiàn)圈通電）
When the valve is cut off and the pipeline leakage fault is eliminated, the staff needs to manually reset it. When they forcefully pull up the manual reset lever and hear a "click" sound, it indicates that the valve is fully opened. At this time, even if the hand is released, it will not be cut off. (Unless the valve coil is energized again)
注：手動(dòng)復(fù)位必須在電磁閥線(xiàn)圈斷電時(shí)操作。
