磁力聯(lián)動(dòng)裝置，UL認(rèn)證
V7系列Flotect流量開關(guān)是一種廉價(jià)的流量開關(guān)，可與兼容液體一起使用，在出現(xiàn)流動(dòng)或無流動(dòng)情況時(shí)啟動(dòng)或停止電子操作設(shè)備。設(shè)計(jì)為標(biāo)準(zhǔn)防風(fēng)雨設(shè)計(jì)，符合NEMA 4X。
產(chǎn)品應(yīng)用
當(dāng)通過加熱線圈的氣流發(fā)生故障時(shí)，鍋爐流量的證明會(huì)關(guān)閉燃燒器保護(hù)泵、電機(jī)和其他設(shè)備，防止低流量或無流量液體冷卻發(fā)動(dòng)機(jī)，當(dāng)冷卻液流動(dòng)中斷時(shí)的機(jī)器和處理
特點(diǎn)
磁力驅(qū)動(dòng)開關(guān)設(shè)計(jì)提供了*的性能
具有一個(gè)自由擺動(dòng)的葉片，它吸引了固體金屬開關(guān)體內(nèi)的磁鐵，通過一個(gè)簡(jiǎn)單的杠桿臂驅(qū)動(dòng)一個(gè)速動(dòng)開關(guān)，沒有波紋管、彈簧或密封件失效
下閥體是實(shí)體加工的確保無泄漏點(diǎn)的金屬棒料，無論機(jī)組運(yùn)行多長(zhǎng)時(shí)間
堅(jiān)固的葉片設(shè)計(jì)是剛性的，并且可在現(xiàn)場(chǎng)調(diào)節(jié)設(shè)定值
