進口液體電磁閥
進口液體電磁閥產品概述
液體電磁閥選用于以水或液體為工作介質,可自動控制或遠程控制水、油、液體等工作介質管路的通斷。由于本閥采用橡膠密封,故對工作介質的清潔度大大減低,具有啟閉迅速,可靠性高等優點。
進口液體用電磁閥工作原理
閥為二次開起的先導式電磁閥,其結構主要由導閥和主閥組成,主閥采用橡膠密封結構。 常位時,活動鐵芯封住導閥口,閥腔內壓力平衡,主閥口封閥。當線圈通電時,產生電磁力將活動鐵芯吸上,主閥腔內的介質自導閥口外泄,以至產生壓力差,膜片或閥杯被迅速托起,主閥口開啟,閥便呈通路了。 當線圈斷電,磁場消失,活動鐵芯復位,封閉導閥口,導閥和主閥腔內壓力平衡后,閥又呈關閉常位。
