The invention relates to an energy-saving electric control valve and an electric control fuel system. The energy-saving electric control valve comprises a shell, a driving source, a guide rod, a firstvalve element, a second valve element and a compressible component. The electric control fuel system comprises a fuel tank, a liquid level sensor, a pressure sensor, a carbon tank and a controller. The liquid level sensor, the pressure sensor and the energy-saving electric control valve are all in electric signal connection with the controller. A first connecting port in the energy-saving electric control valve is connected with an exhaust port in the fuel tank, a second connecting port is connected with an air inlet in the carbon tank, a third connecting port is connected with an atmosphericpipeline, and a fourth connecting port is connected with an exhaust port in the carbon tank. According to the energy-saving electric control valve and the electric control fuel system, with the energy-saving electric control valve, communication between the fuel tank and the carbon tank is cut off, it is avoided that oil vapor enters the carbon tank and causes overlarge load of the carbon tank, and less environmental pollution is caused; and the opening degree of a channel can be controlled by controlling the moving distance of a driving source, and the volume is accurately controlled in theprocess of filling and supplementing fuel oil.
本发明涉及一种节能型电控阀及电控燃料系统,节能型电控阀包括壳体、驱动源、导杆、第一阀芯、第二阀芯及可压缩部件。电控燃料系统包括燃油箱、液位传感器、压力传感器、碳罐及控制器;液位传感器、压力传感器及节能型电控阀均与控制器电信号连接;节能型电控阀上的第一连接口与燃油箱上的排气口连接,第二连接口与碳罐上的进气口连接,第三连接口与通大气管路连接,第四连接口与碳罐上的排气口接。节能型电控阀实现阻断燃油箱和碳罐的连通,避免油蒸气进入碳罐,导致碳罐负载过大,降低环境污染;通过控制驱动源移动的距离可以实现对通道开度的控制,在加注和补加燃油的过程中,精确控制容积。
