品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口燃气紧急切断电磁阀在日常工作中处于常开状态，电磁阀线圈处于断电状态，不消耗电能 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

当事故发生时，系统发出型号，阀门线圈瞬时通电，触发阀门快速关闭，并进入自锁状态 When an accident occurs, the system issues a model number, and the valve coil is momentarily energized, triggering the valve to close and enter a self-locking state

当工作人员处理完事故，人工重新开启阀门，才会恢复供气 only when the staff have handled the accident and manually reopened the valve can gas supply be restored

阀门采用先导式阀瓣，开启轻松，即使压力达到6Bar开启也十分轻松，口径大于DN125，采用杠杆手柄，使阀门达到开关省力、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

根据客户要求也可提供断电关闭的常闭型紧急切断阀 According to customer re, a normally closed emergency shut-off valve can also be provided for power-off closure

进口燃气紧急切断电磁阀控制原理--Control principle of imported gas emergency shut-off solenoid valve

常开--阀关闭后在通电或断电都不会自动开启，需手动拉开，保持打开状态，节能、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.阀需要打开时，旋下防护罩，用力拉手柄，阀打开 When the valve needs to be opened, unscrew the protective cover and forcefully pull the handle to open the valve

2.阀需要关闭时，线圈通电不超过30秒钟，阀迅速关闭 When the valve needs to be closed, the coil is energized for no more than 30 seconds and the valve closes

手动复位操作过程-- Manual reset operation process

当阀门被切断，管道漏气故障排出后，工作人员需要手动复位时，用力向上提拉手动复位杆，听到“咔”的一声，说明阀门完全被打开，此时，即使松开手，也不会被切断。（除非再给阀门线圈通电）

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：手动复位必须在电磁阀线圈断电时操作。

进口燃气紧急切断电磁阀应用--

RETZ燃气紧急切断阀是新型的燃气管道工程的安全配套装置，主要应用于以下场合：

1、与可燃气体泄漏监测仪器相连接。当仪器检测到可燃气体泄漏，自动快速关闭主供气体阀门。切断燃气的供给，及时制止而恶性事故的发生。

2、与热力设备的极限温度（或压力）安全阀控制连接；当设备内检测点的温度或压力超过设定的极限数值时，自动快速关闭供气阀门，停止燃料的供给。

3、与高层建筑的中央消防报警系统相连接。当大厦发生火警时，自动切断大厦内的燃气供应，防止煤气爆炸的发生。

4、在城市或工厂的燃气供应管网内设置BZCK燃气紧急切断阀，可在中央控制室内集中控制，远距离遥控，紧急关闭事故现场的管线供气。

5、可靠的技术性能，极低的负荷损失，极高的安全性能，快速切断性能。
