一、进口自保式电磁阀产品概述：

德国《LOCKE》洛克--进口自保式电磁阀采用具有机械式自锁记忆功能的双先导结构的自保持式。当部件线圈通电，电磁阀打开，然后断电，此时电磁阀为常通状态，当部件线圈通电，电磁阀关闭，然后断电，此时电磁阀为常闭状态。若线圈同时通电，此时电磁阀为常通状态，线圈也不会因此烧坏。

1、 Overview of imported self-protection solenoid valve products:

German "Locke" Locke imported self-protection solenoid valve adopts self-protection type with double pilot structure with mechanical self-locking memory function. When the component coil is energized, the solenoid valve is opened and then de energized. At this time, the solenoid valve is normally closed. When the component coil is energized, the solenoid valve is closed and then de energized. At this time, the solenoid valve is normally closed. If the coil is energized at the same time, the solenoid valve is in the normal state, and the coil will not burn out.

四、进口自保式电磁阀工作原理：

现有的电磁阀是由壳体、放置在壳体内的骨架及线圈、装在骨架内的活塞套管及内部装有复位弹簧、下端有顶杆的活塞组成。实际连接时，电磁阀引线通过控制开关接电源，活塞套管通过法兰与管路主控制阀相连。当电磁阀得电时，处于开启状态;反之，则处于关闭状态。由于在实际控制中，大部分时间都要接通主管路，因此，电磁阀相应也要在接电状态下工作。这样，就使得电磁阀耗电大，特别是大型电磁阀，耗电非常大，使得生产运行成本增大。

4、 Working principle of imported self-protection solenoid valve:

The existing solenoid valve is composed of a shell, a framework and a coil placed in the shell, a piston sleeve installed in the framework and a piston with a return spring inside and a top rod at the lower end. In actual connection, the lead wire of the solenoid valve is connected to the power supply through the control switch, and the piston sleeve is connected to the main control valve of the pipeline through the flange. When the solenoid valve is powered on, it is in the open state; On the contrary, it is closed. In the actual control, the main pipe is connected most of the time, so the solenoid valve should also work in the power on state. In this way, the power consumption of solenoid valve is large, especially for large solenoid valve, which increases the production and operation cost.
