VICKERS威格士電磁閥(fa)(fa)是由(you)單向(xiang)閥(fa)(fa)、安全閥(fa)(fa)、進油(you)體、回油(you)體和多(duo)個換(huan)向(xiang)閥(fa)(fa)片組合而成的組合閥(fa)(fa)。以手(shou)動換(huan)向(xiang)為主(zhu)。它具有結(jie)構緊湊、工作(zuo)(zuo)壓力、性能(neng)異、工作(zuo)(zuo)可靠等(deng)特點。

VICKERS電磁閥的作用是只允許介質向一個方向流動，阻止方向流動。通常這種閥門是自動工作，一個方向流動流體壓力作用下，閥瓣打開；流體反方向流動時，由流體壓力和閥瓣自重合閥瓣作用于閥座，切斷流動。其中止回閥就屬于這種類型閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構，還有一個像門一樣閥瓣自由靠傾斜閥座表面上
