丹富斯電動三通球閥、電動三通球閥作用             丹富斯電動三通球閥、電動三通球閥作用

VQF電動閥門的工作電壓分別為（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，請接額定工作電壓的電源。另兩根黃色線為閥門的關(guān)通控制線。電源接通后，當(dāng)將兩根黃線相連時，閥門將從全關(guān)時轉(zhuǎn)到全通，全行程時間約10秒鐘，此時紅色指示燈亮表示全通。如將兩根黃色線分開，閥門又從全通回到全關(guān)，此時綠色指示燈亮表示閥門全關(guān)。LDVQF還設(shè)有自動保護(hù)系統(tǒng)，閥門在運行中如遇流動物體有雜質(zhì)將閥門卡死，或其他故障，VQF系統(tǒng)會自動切斷電機電源，并發(fā)出“嘟……”報警聲。此時應(yīng)關(guān)閉電源，取出雜物，排除故障，再通電運作。所以流動物體中有雜物的用戶，使用LDVQF時應(yīng)在閥門前加裝過濾網(wǎng)，進(jìn)行保護(hù)。
VQF電動閥門采用通用球閥，配合特定設(shè)計的電動執(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),動作可靠,安全性好,壽命大于500000次,而且還是個節(jié)能型產(chǎn)品，只在動作時耗電.更重要的是其價格低,比相同通經(jīng)的電磁閥價格還低               

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
