燃气紧急切断阀（常开型）

→产品特点

（RFK）罗伯特燃气紧急切断阀阀断电后、迅速关闭；阀再次通电，不会自动打开。必须靠手动拉起阀门，保持打开伏态；节能、线圈保持功耗15W、温度不超过10℃、可长期通电口；密封性好、零泄漏。

Germany Robert RFK imported gas fast cut off valve Product characterislic, valve power failure, after rapid closing valve,again energized,not automatically open,must rely on manual pull valve,remains open:energy-saving,coif to maintain the power 15W,temperature of not more than 10 DEsC,can be long-term electricityGood seal,zero leakage.

→应用范围

→工作原理

当电磁一田需打开时，电磁阀线圈先得电，然后把阀顶部的保护套旋下，用力向外拉起手柄，电磁阀打开，然后将保护套装在原位保护手柄。当电磁阀需关闭时。线圈瞬间断电。电磁阀迅速关闭。

Working principle: when the solenoid valve is opened, the coil of the

solenoid valve to have electricity, and then the valve at the tap of the

protective sleeve rotation, forced outward pull handle,the solenoid valve is opened,and then the protective suit of in situ protection handle.When Lhe electromagnetic valve is closed,the coil is instantaneously loses electricity,the electromagnetic valve quickl cIose.

→注解 Note

流体中若含有杂质，电磁阀进端必须安装过滤器，二进一出的工作原理的电磁阀两端压力不相等时，需加止回阀。可安装止回阀或订制自带止回功能的阀门。

if the fluid contains impurities,solenoid valve into the end must be installed in the filter,two into a working principle of the solenoid valve two inlet end pressure is not equal,the need to add check valve.Can be installed check valve or custom comes with a return function of the valve.
