德国莱克（LIK）品牌：进口低温电磁阀应用范围： 产品特点：
阀芯均为不锈钢活塞式，活塞环用特殊耐低温、耐磨材料制作；活塞与金属阀腔不产生直接摩擦，阀体安装方向无限制；特制线圈，不易烧毁；长时间停止动作重新启动，作同样灵敏。 主要技术参数：
工作原理：
常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开；当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。 常开：当线圈通电时，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。 规格尺寸：
Applications:
It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems. Features:
Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity. Main technical parameters:
How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, medium pressure piston push the lower chamber, the electromagnetic valve is opened. Size:
Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve |
电磁阀的应用和选择注意要点
原文：
电磁阀的故障将直接影响到切换阀和调节阀的动作，常见的故障有电磁阀不动作，应从以下几方面排查：
（1）电磁阀接线头松动或线头脱落，电磁阀不得电，可紧固线头。
（2）电磁阀线圈烧坏，可拆下电磁阀的接线，用万用表测量，如果开路，则电磁阀线圈烧坏。
原因有线圈受潮，引起绝缘不好而漏磁，造成线圈内电流过大而烧毁，因此要防止雨水进入电磁阀。此外，弹簧过硬，反作用力过大，线圈匝数太少，吸力不够也可使得线圈烧毁。紧急处理时，可将线圈上的手动按钮由正常工作时的“0"位打到“1"位，使得阀打开。
（3）电磁阀卡住。电磁阀的滑阀套与阀芯的配合间隙很小（小于0.008mm），一般都是单件装配，当有机械杂质带入或润滑油太少时，很容易卡住。处理方法可用钢丝从头部小孔捅入，使其弹回。根本的解决方法是要将电磁阀拆下，取出阀芯及阀芯套，用CCI4清洗，使得阀芯在阀套内动作灵活。拆卸时应注意各部件的装配顺序及外部接线位置，以便重新装配及接线正确，还要检查油雾器喷油孔是否堵塞，润滑油是否足够。
（4）漏气。漏气会造成空气压力不足，使得强制阀的启闭困难，原因是密封垫片损坏或滑阀磨损而造成几个空腔窜气。
在处理切换系统的电磁阀故障时，应选择适当的时机，等该电磁阀处于失电时进行处理，若在一个切换间隙内处理不完，可将切换系统暂停，从容处理。电磁阀的应用和选择注意要点。

Solenoid valve failure will directly affect the switching valve and valve action, a common fault with the solenoid valve does not move, the investigation from the following aspects:
(1) the electromagnetic valve head loose or thread off wiring, electric solenoid valve shall be fastened thread.
(2) the solenoid valve coil burned out, can remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned.
Moisture causes the coil, magnetic flux leakage caused by bad insulation, causing the coil current is too large to burn, so to prevent flood water from entering the solenoid valve. In addition, excellent spring, reaction force is too large, too few coil turns, the suction can not make the coil burnt. Emergency treatment, can be "0" bit hit "1" bit manual button on the coil from the normal work, makes the valve open.
(3) solenoid valve stuck. Slide valve sleeve and spool solenoid valve with a small gap (less than 0.008mm), are generally single assembly, when a mechanical impurities into or too little lubricant, it is easy to get stuck. Treatment can hold into the wire hole from the head to make it bounce. The fundamental solution is to remove the valve, remove the spool and spool cover, clean with CCI4, making flexible movement in the valve spool sleeve. Demolition should pay attention to the assembly sequence and location of the external connection of each component, in order to re assembly and wiring is correct, also check whether the plug hole injector lubricator, lubricating oil is sufficient.
(4) leakage. Lack of air pressure can cause leakage, making enforcement difficult to open and close the valve, the reason is the slide valve gasket damage or wear caused by several cavity channeling gas.
In dealing with the electromagnetic valve failure switching system, should select the appropriate time, such as the solenoid valve is energized when dealing with, if not processed in a gap switch, switching system can be suspended, calm handling.
