Barksdale巴士德壓力開關(guān)在雨淋閥上的應(yīng)用
雨淋閥動作過程中壓力開關(guān)的作用:
當(dāng)發(fā)生火災(zāi)時，現(xiàn)場的探測設(shè)備動作，聯(lián)動開啟雨淋閥的先導(dǎo)電磁閥，從而打開雨淋閥，供水側(cè)的水流進系統(tǒng)側(cè)，水力警鈴和壓力開關(guān)開始動作。壓力開關(guān)在感應(yīng)到系統(tǒng)壓力時兩組觸點吸合，一組信號發(fā)送給中控系統(tǒng)用于報警，一組信號發(fā)送給水泵控制系統(tǒng)用于主泵啟動供水。
技術(shù)要求:
工作介質(zhì)清水
外殼316不銹鋼
防護等級IP66
防爆等級EXdICT6
開關(guān)類型雙刀雙擲(DPDT)
設(shè)定值上升0.0350.05MPa
工作壓力0.02~1.6MPa
電壓DC24V
