品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口燃氣緊急切斷電磁閥在日常工作中處于常開狀態，電磁閥線圈處于斷電狀態，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

當事故發生時，系統發出型號，閥門線圈瞬時通電，觸發閥門快速關閉，并進入自鎖狀態 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

當工作人員處理完事故，人工重新開啟閥門，才會恢復供氣 Only when the staff have handled the accident and manually reopened the valve can gas supply be restored

閥門采用先導式閥瓣，開啟輕松，即使壓力達到6Bar開啟也十分輕松，口徑大于DN125，采用杠桿手柄，使閥門達到開關省力、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

根據客戶要求也可提供斷電關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

進口燃氣緊急切斷電磁閥控制原理--Control principle of imported gas emergency shut-off solenoid valve

常開--閥關閉后在通電或斷電都不會自動開啟，需手動拉開，保持打開狀態，節能、安全 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.閥需要打開時，旋下防護罩，用力拉手柄，閥打開 When the valve needs to be opened, unscrew the protective cover and forcefully pull the handle to open the valve

2.閥需要關閉時，線圈通電不超過30秒鐘，閥迅速關閉 When the valve needs to be closed, the coil is energized for no more than 30 seconds and the valve quickly closes

手動復位操作過程-- Manual reset operation process

當閥門被切斷，管道漏氣故障排出后，工作人員需要手動復位時，用力向上提拉手動復位桿，聽到“咔”的一聲，說明閥門完全被打開，此時，即使松開手，也不會被切斷。（除非再給閥門線圈通電）

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：手動復位必須在電磁閥線圈斷電時操作。

進口燃氣緊急切斷電磁閥應用--

RETZ燃氣緊急切斷閥是新型的燃氣管道工程的安全配套裝置，主要應用于以下場合：

1、與可燃氣體泄漏監測儀器相連接。當儀器檢測到可燃氣體泄漏，自動快速關閉主供氣體閥門。切斷燃氣的供給，及時制止而惡性事故的發生。

2、與熱力設備的極限溫度（或壓力）安全閥控制連接；當設備內檢測點的溫度或壓力超過設定的極限數值時，自動快速關閉供氣閥門，停止燃料的供給。

3、與高層建筑的中央消防報警系統相連接。當大廈發生火警時，自動切斷大廈內的燃氣供應，防止煤氣爆炸的發生。

4、在城市或工廠的燃氣供應管網內設置BZCK燃氣緊急切斷閥，可在中央控制室內集中控制，遠距離遙控，緊急關閉事故現場的管線供氣。
