美国派克电磁阀

　　美国派克parker电磁阀货期短型号全：

　　直动式电磁阀是一种不需要压力启动（零压启动）的电磁阀，常适用于小口径、低压力或真空情况下的管道中，并且响应速度非常快，动作时间很短，对于启闭频率比较高或要求快速关断的场合，都特别适合选用直动式电磁阀。

　　直动式电磁阀，通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开;断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。

　　它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开;断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。

　　直动式电磁阀特点：

　　直动式电磁阀采用直动式原理，膜片结构，具有结构简单，零件少，反应迅速，动作灵敏等特点，可任意方式安装，但功耗比先导式电磁阀大，一般在5-20w，高频通电容易烧毁线圈，但是控制简单，使用范围广。

　　在真空、负压、零压时能正常工作，通径一般不超过25mm。

　　2.在零压差或真空、高压时亦可动作，但功率较大，要求必须水平安装。

　　工作原理

　　1）常闭型，通电时电磁线圈产生足够的电磁力把运动部件（由磁芯、阀杆、上下部的膜片/密封件构成）从阀座上提起，阀门开启;断电时弹簧力把运动部件压在阀座上，阀门关闭。

　　2）常开型，动作方向与常闭型相反。
