電磁閥是一種機(jī)電設(shè)備,允許一個(gè)電氣設(shè)備控制氣體或液體的流動(dòng)。電氣設(shè)備使電流流過(guò)線圈位于電磁閥。這反過(guò)來(lái)導(dǎo)致電流磁場(chǎng)導(dǎo)致金屬致動(dòng)器的位移。 執(zhí)行機(jī)構(gòu)是機(jī)械與機(jī)械閥電磁閥內(nèi)。然后閥改變狀態(tài),打開或關(guān)閉允許液體或氣體流經(jīng)或電磁閥被阻塞。春天是用來(lái)返回執(zhí)行機(jī)構(gòu)和閥回到靜息狀態(tài)的電流時(shí)刪除。 電磁閥有各種尺寸和配置。電磁閥可以常開、常閉或雙向閥。一個(gè)常開電磁閥允許液體或氣體流經(jīng)除非電流應(yīng)用于電磁閥。一個(gè)常閉閥以相反的方式工作。雙向電磁閥有三個(gè)港口,一個(gè)端口是常見的,一個(gè)是常開,第三是常閉。 工廠自動(dòng)化使電磁閥頻繁使用。計(jì)算機(jī)設(shè)備運(yùn)行一個(gè)工廠自動(dòng)化項(xiàng)目來(lái)填補(bǔ)一個(gè)容器和一些液體可以將一個(gè)信號(hào)發(fā)送到電磁閥打開,允許容器填滿,然后刪除信號(hào)關(guān)閉電磁閥,停止流動(dòng)的液體,直到下一個(gè)容器。機(jī)器人上的爪抓項(xiàng)目經(jīng)常一個(gè)空氣控制裝置?？梢允褂秒姶砰y允許空氣壓力關(guān)閉鉗子,和第二電磁閥可用于打開夾。如果使用兩路電磁閥,兩個(gè)單獨(dú)的閥門不需要在這個(gè)應(yīng)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.
