<**n style="overflow-wrap: break-word; font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei"; position: unset !important;">礦用隔爆型電磁閥主要用于礦井下有瓦斯濃度比較高的礦井下使用，主要是用于皮帶機上的灑水裝置，皮帶機一直運費，摩擦溫度過高就容易引起火災引起瓦斯爆炸

<**n style="overflow-wrap: break-word; font-size: 16px; font-family: 微軟雅黑, "Microsoft YaHei"; position: unset !important;">，所以避免這種失誤發生，皮帶機上bi須安裝電磁閥灑水系統，電磁閥和溫度傳感器，速度傳感器，等一起鏈接在主機上面。
