美國派克parker電磁閥貨期短型號全：

　　直動式電磁閥是一種不需要壓力啟動（零壓啟動）的電磁閥，常適用于小口徑、低壓力或真空情況下的管道中，并且響應速度非?？?，動作時間很短，對于啟閉頻率比較高或要求快速關斷的場合，都特別適合選用直動式電磁閥。

　　直動式電磁閥，通電時，電磁線圈產(chǎn)生電磁力把關閉件從閥座上提起，閥門打開;斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。

　　它是一種直動和先導式相結合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開;斷電時，先導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。

　　直動式電磁閥特點：

　　直動式電磁閥采用直動式原理，膜片結構，具有結構簡單，零件少，反應迅速，動作靈敏等特點，可任意方式安裝，但功耗比先導式電磁閥大，一般在5-20w，高頻通電容易燒毀線圈，但是控制簡單，使用范圍廣。

　　在真空、負壓、零壓時能正常工作，通徑一般不超過25mm。

　　2.在零壓差或真空、高壓時亦可動作，但功率較大，要求必須水平安裝。

　　工作原理

　　1）常閉型，通電時電磁線圈產(chǎn)生足夠的電磁力把運動部件（由磁芯、閥桿、上下部的膜片/密封件構成）從閥座上提起，閥門開啟;斷電時彈簧力把運動部件壓在閥座上，閥門關閉。

　　2）常開型，動作方向與常閉型相反。
