进口带信号反馈电磁阀 Imports with signal feedback solenoid valve
一、结构原理 First, the structural principle
常开型—在工作状态中电磁阀处于开启状态，线圈不带电，当发生燃气泄露时，电磁阀瞬间通电切断气源，但必须在险情排除后，由人工打开电磁阀。常闭型—在工作状态中电磁阀处于开启状态，线圈处于带电状态，将信号线输入DC24V电源信号（综色为+；蓝色为—），信号灯不亮，阀门处于开启状态。当发生燃气泄露时，电磁阀瞬间断电切断气源，此时，信号灯亮，黑色（+）与棕色（—）线将输出一个DC24V电源信号。开启时，先将手动装置提到位（提不动为止），再通上电源,再放手即可。缺点为停电情况时电磁阀不能打开。
Structural principle normally open type - in working condition, the solenoid valve is open, the coil is not charged when a gas leak occurs, the solenoid valve is energized momentarily cut off the gas source, but must be in danger is removed by hand to open the solenoid valve. Normally closed solenoid valve is turned on - in working condition, the coil in a charged state, the signal line input DC24V power signal （the Brown +; blue -）, the signal light is not lit, the valve is open. When a gas leak occurs, the solenoid valve instant power failure cut off the gas source, the signal light, black （+） and brown （-） cable to a DC24V power output signal. Open, first mentioned in the manual device a bit （not to mention it stops）, and then pass on the power supply, you can let go. Disadvantage of the solenoid valve can not be opened for the power outage situation.

三、进口带信号反馈电磁阀安装保养 The imports with signal feedback solenoid valve installation and maintenance
1、安装时电磁阀线圈向上，并保持垂直位置，电磁阀上箭头应与管道流向*。
installation solenoid valve coil upward, and maintain the vertical position, the arrow on the solenoid valve should be consistent flow and pipeline.
2、电磁阀应保证在电源电压为额定电压的15%-10%波动范围内正常工作。
the solenoid valve should ensure that the normal fluctuations in the range of 15% -10% of the rated voltage of the power supply voltage.
3、电磁阀的工作介质应清洁无杂质，电磁阀内件及过滤器，需定期清洁干净。
the working medium of the solenoid valve should be clean and free of impurities, solenoid valve parts and filters, need to be regularly cleaned.
4、在电磁阀发生故障时，为了保证系统正常运行，安装旁路装置
when the solenoid valve failure, in order to ensure the normal operation of the system, it is best to install a bypass device
5、管道必须清洗干净。建议在阀前安装过滤器，蒸汽管道安装疏水阀。
the pipeline must be cleaned. Proposed filter installed in the front of the valve, steam pipes installed traps.
6、不能将阀安装在管道的低凹处，以免因蒸汽冷凝水沉淀在阀内而防碍动作。
not the valve installed in the low cavity of the pipe, so as not to hinder action of steam condensate is precipitated in the valve.
7、管道中不得有反向压差。并需通电数次，使之适温后方可正式投入使用。
the pipe must not reverse the pressure difference. And be energized several times, so that optimum temperature before officially put into use.
8、在管路刚性不足情况下，建议把阀前管道固定，以免电磁阀工作时引起振动。
in rigid piping insufficient case, it is recommended that the valve before the pipe is fixed, so as not to cause vibration when the solenoid valve work.
9、在安装前，请认真阅读使用说明书，判断产品是否符合使用条件。
before installation, carefully read the instruction manual to determine whether the products comply with the conditions of use.
