        電動(dòng)球閥工作原理是由藍(lán)色的執(zhí)行器帶動(dòng)閥體中的球型密封閥門(mén)做90°的旋轉(zhuǎn),實(shí)現(xiàn)閥體的導(dǎo)通與關(guān)閉,達(dá)到控制介質(zhì)通斷目的。選擇的電動(dòng)球閥應(yīng)具有小體積,合理結(jié)構(gòu),執(zhí)行機(jī)構(gòu)全部密封,防水性好,可在惡劣場(chǎng)合使用。
        電動(dòng)球閥技術(shù)特點(diǎn)有:電動(dòng)球閥是以大功率電動(dòng)機(jī)為動(dòng)力驅(qū)動(dòng)球型閥,閥的開(kāi)與閉是利用定位準(zhǔn)確的微觸點(diǎn)開(kāi)關(guān)與電子控制器轉(zhuǎn)換來(lái)實(shí)現(xiàn):僅需220V, 50Hz 交流電源:控制方式簡(jiǎn)單——三根控制線斷開(kāi)狀態(tài)對(duì)應(yīng)閥門(mén)全部關(guān)死狀態(tài)。兩根控制線短接狀態(tài)(不需外加電源),對(duì)應(yīng)閥門(mén)全部打開(kāi)狀態(tài);全流量、阻力小、體積小,打開(kāi)或關(guān)閉時(shí)間約8s。
