丹富斯电动三通球阀、电动三通球阀作用             丹富斯电动三通球阀、电动三通球阀作用

VQF电动阀门的工作电压分别为（AC12V、AC24V、AC220V)，其操作和和控制方式：执行器有四根引线，其中两根为红色，另两根为黄色。两根红色线为工作电源线，请接额定工作电压的电源。另两根黄色线为阀门的关通控制线。电源接通后，当将两根黄线相连时，阀门将从全关时转到全通，全行程时间约10秒钟，此时红色指示灯亮表示全通。如将两根黄色线分开，阀门又从全通回到全关，此时绿色指示灯亮表示阀门全关。LDVQF还设有自动保护系统，阀门在运行中如遇流动物体有杂质将阀门卡死，或其他故障，VQF系统会自动切断电机电源，并发出“嘟……”报警声。此时应关闭电源，取出杂物，排除故障，再通电运作。所以流动物体中有杂物的用户，使用LDVQF时应在阀门前加装过滤网，进行保护。
VQF电动阀门采用通用球阀，配合特定设计的电动执行器组合成一体，其结构紧凑,体积小,重量轻,流通阻力特小,可作流量调节,动作可靠,安全性好,寿命大于500000次,而且还是个节能型产品，只在动作时耗电.更重要的是其价格低,比相同通经的电磁阀价格还低               

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
