The solenoid valve consists of a solenoid coil and a magnetic core, which is a valve body with one or more holes. When the coil is energized or de energized, core operation will cause the fluid to pass through the body or be cut off to change the direction of the fluid. The electromagnetic components of the solenoid valve are composed of fixed iron core, moving iron core and coil; the valve body is composed of slide valve core, slide valve sleeve, spring seat, etc. The electromagnetic coil is directly installed on the valve body, and the valve body is sealed in the sealed pipe, forming a simple and compact combination.

　　工厂中常用的电磁阀有二二、三四;电磁阀的“通”和“位”是换向阀的重要概念。

　　There are two or three or four commonly used solenoid valves in the factory. The "on" and "position" of the solenoid valve are important concepts of the reversing valve.

　　位置是指阀芯的状态;

　　Position refers to the status of valve core;

　　“二阀”是指阀芯状态只有两种，即“开”和“关”;对应的电气系统是指单个电磁阀线圈的带电和失电。

　　"Two valves" means that there are only two valve core States, namely "on" and "off"; the corresponding electrical system refers to the charging and power loss of a single solenoid valve coil.

　　“三阀”是指阀芯状态有三个即“开”、“关”和“中”;对于电气系统，它是指两个线圈一起使用的三种状态(A得到电力，B失去电力;2 A断电，B断电，3 AB断电)。

　　"Three valves" refers to three valve core States, i.e. "on", "off" and "medium"; for electrical system, it refers to three states used together by two coils (a gets power, B loses power; 2 a cuts off power, B cuts off power, 3 AB cuts off power).

　　阀体未连接到管道接口，不同管道的切换是由阀芯动作控制的，通道的变化意味着管道介质的变化，即外部设备的移动;

　　The valve body is not connected to the pipeline interface, and the switching of different pipelines is controlled by the action of valve core. The change of channel means the change of pipeline medium, that is, the movement of external equipment;

　　电磁阀在PLC系统应用,PLC控制继电器输出,继电器触点闭合意志力电磁阀线圈,线圈电力驱动轴动作,通过媒介的变化的控制电路来控制外部设备的作用,媒介通常是石油或天然气

　　The application of solenoid valve in PLC system, PLC control relay output, relay contact closing willpower solenoid valve coil, coil electric drive shaft action, control the role of external equipment through the control circuit of medium change, the medium is usually oil or natural gas

　　本厂更常用的电磁阀是二通电磁阀、二通电磁阀和三通电磁阀;

　　The most commonly used solenoid valves in our factory are two-way solenoid valve, two-way solenoid valve and three-way solenoid valve;

　　通常两个双向电磁阀由一个线圈,PLC或其他系统输出点控制,线圈通电时打开或关闭,没有行动,只上的电磁阀控制运动,运动需要配合机械状态,所以这两个双向电磁阀安全阀系统中更为常见。

　　Generally, two two-way solenoid valves are controlled by one coil, PLC or other system output points. When the coil is powered on, it is opened or closed without action. Only the upper solenoid valve controls the movement. The movement needs to cooperate with the mechanical state, so the two-way solenoid valve safety valve systems are more common.

　　二位三通电磁阀还含有一个线圈，由PLC或其他系统的输出点控制，即接通电源时为打开或关闭状态，断开电源时为相反动作;该电磁阀适用于简单重复运动的机械结构，如单线圈控制气缸。

　　The two position three-way solenoid valve also contains a coil, which is controlled by the output point of PLC or other systems, that is, when the power is turned on, it is in the open or closed state, and when the power is turned off, it is in the opposite action; the solenoid valve is applicable to the mechanical structure of simple repetitive motion, such as single coil control cylinder.

　　三通四通电磁阀有两个线圈,PLC或其他系统的两个输出点控制两个线圈,也就是说,当线圈通电打开或关闭时,另一个线圈激励行动恰恰相反,没有电磁阀输出将保持原来的状态,同时两个线圈不能精力充沛;电磁阀适用于行程大，需要位置传感器的机械结构。

　　There are two coils for the three-way four-way solenoid valve, and two output points of PLC or other systems control two coils. That is to say, when the coil is electrified on or off, the excitation action of the other coil is exactly the opposite. Without the solenoid valve output, the original state will be maintained, while the two coils cannot be energetic; the solenoid valve is applicable to the mechanical structure of the position sensor with large stroke.

　　工厂中更常见的电磁阀为以上几种，除了一些特殊的电磁阀，如四通阀、五通阀等，它们都有自己的用途，但经过学习掌握原理后就可以正确使用。

　　The most common solenoid valves in the factory are the above. In addition to some special solenoid valves, such as four-way valve and five-way valve, they all have their own purposes, but they can be used correctly after learning and mastering the principle.

　　总结;阀芯会有几个位置就是几个阀门;阀体上有几个出口就是几个阀门，所以理解起来会很方便。

　　Summary: several positions of valve core are several valves; several outlets of valve body are several valves, so it is very convenient to understand.
