电磁阀是什么?

电磁阀是一种机电设备,允许一个电气设备控制气体或液体的流动。电气设备使电流流过线圈位于电磁阀。这反过来导致电流磁场导致金属致动器的位移。 执行机构是机械与机械阀电磁阀内。然后阀改变状态,打开或关闭允许液体或气体流经或电磁阀被阻塞。春天是用来返回执行机构和阀回到静息状态的电流时删除。 电磁阀有各种尺寸和配置。电磁阀可以常开、常闭或双向阀。一个常开电磁阀允许液体或气体流经除非电流应用于电磁阀。一个常闭阀以相反的方式工作。双向电磁阀有三个港口,一个端口是常见的,一个是常开,第三是常闭。 工厂自动化使电磁阀频繁使用。计算机设备运行一个工厂自动化项目来填补一个容器和一些液体可以将一个信号发送到电磁阀打开,允许容器填满,然后删除信号关闭电磁阀,停止流动的液体,直到下一个容器。机器人上的爪抓项目经常一个空气控制装置。可以使用电磁阀允许空气压力关闭钳子,和第二电磁阀可用于打开夹。如果使用两路电磁阀,两个单独的阀门不需要在这个应用程序中。

A solenoid is an electromechanical device which allows for an electrical device to control the flow of a gas or liquid. The electrical device causes a current to flow through a coil located on the solenoid valve. This current flow in turn results in a magnetic field which causes the displacement of a metal actuator.    The actuator is mechanically linked to a mechanical valve inside the solenoid valve. The valve then changes state, either opening or closing to allow a liquid or gas to either flow through or be blocked by the solenoid valve. A spring is used to return the actuator and valve back to their resting state when the current flow is removed.    Solenoid valves have  various sizes and configurations. Solenoid valves can be normally open, normally closed, or a two way valve. A normally open solenoid valve allows a liquid or gas to flow through unless a current is applied to the solenoid valve. A normally closed valve works in the opposite manner. A two way solenoid valve has three ports; one port is common, one is normally open and the third is normally closed.    Factory automation makes frequent use of solenoid valves. A computer device running a factory automation program to fill a container with some liquid can send a signal to the solenoid valve to open, allowing the container to fill, and then remove the signal to close the solenoid valve and stop the flow of liquid until the next container is in place. A gripper for grasping items on a robot is frequently an air controlled device. A solenoid valve can be used to allow air pressure to close the gripper, and a second solenoid valve can be used to open the gripper. If a two way solenoid valve is used, two separate valves are not needed in this application.
