丹富斯電動(dòng)三通球閥、電動(dòng)三通球閥作用             丹富斯電動(dòng)三通球閥、電動(dòng)三通球閥作用

VQF電動(dòng)閥門(mén)的工作電壓分別為（AC12V、AC24V、AC220V)，其操作和和控制方式：執(zhí)行器有四根引線，其中兩根為紅色，另兩根為黃色。兩根紅色線為工作電源線，請(qǐng)接額定工作電壓的電源。另兩根黃色線為閥門(mén)的關(guān)通控制線。電源接通后，當(dāng)將兩根黃線相連時(shí)，閥門(mén)將從全關(guān)時(shí)轉(zhuǎn)到全通，全行程時(shí)間約10秒鐘，此時(shí)紅色指示燈亮表示全通。如將兩根黃色線分開(kāi)，閥門(mén)又從全通回到全關(guān)，此時(shí)綠色指示燈亮表示閥門(mén)全關(guān)。LDVQF還設(shè)有自動(dòng)保護(hù)系統(tǒng)，閥門(mén)在運(yùn)行中如遇流動(dòng)物體有雜質(zhì)將閥門(mén)卡死，或其他故障，VQF系統(tǒng)會(huì)自動(dòng)切斷電機(jī)電源，并發(fā)出“嘟……”報(bào)警聲。此時(shí)應(yīng)關(guān)閉電源，取出雜物，排除故障，再通電運(yùn)作。所以流動(dòng)物體中有雜物的用戶(hù)，使用LDVQF時(shí)應(yīng)在閥門(mén)前加裝過(guò)濾網(wǎng)，進(jìn)行保護(hù)。
VQF電動(dòng)閥門(mén)采用通用球閥，配合特定設(shè)計(jì)的電動(dòng)執(zhí)行器組合成一體，其結(jié)構(gòu)緊湊,體積小,重量輕,流通阻力特小,可作流量調(diào)節(jié),動(dòng)作可靠,安全性好,壽命大于500000次,而且還是個(gè)節(jié)能型產(chǎn)品，只在動(dòng)作時(shí)耗電.更重要的是其價(jià)格低,比相同通經(jīng)的電磁閥價(jià)格還低               

VQF the working voltage of electric valve (AC12V, AC24V, AC220V), respectively, the operation and control mode: four actuators have lead, two of the root to red, the other two for yellow. Two red thread to work the power cord, please pick up the rated working voltage of power supply. The other two yellow thread for GuanTong control line of the valve. After power on, when that connected the two root yellow line, the valve will transfer from when fitted to all pass, total travel time for 10 seconds, the red indicator all-pass said. Such as separated the two root yellow line, again from the back to close, the green light is lit said valve seated at this time. LDVQF also is equipped with automatic protection system, in case of objects have impurities in the operation of the valve in the valve stuck, or other fault, VQF system will automatically cut off the motor power, and issued a "du..." Alarm. At this time should be shut off the power, sundries, troubleshooting, and electricity. So the flow of sundry user object, using LDVQF should add filter before the valve, for their own protection. 
VQF using universal ball valve, electric valve electric actuator with specific design combined into an organic whole, its structure is compact, small volume, light weight, small flow resistance, and can make flow control, reliable operation, good safety, life is more than 500000 times, but also a energy-saving products, only when the action power. More important is its low price, than electromagnetic valve of the same pass after the price is low
