The invention relates to the technical field of nozzle solenoid valves, in particular to a nozzle solenoid valve of a urea pump, comprising an electromagnetic controller, a surface of the electromagnetic controller is fixedly connected with a casing assembly, and the casing assembly is composed of a fixed nut, a first fixed casing and a A second fixing shell is formed, the bottom end of the fixing nut is threadedly connected with the top end of the first fixing shell, and the inner cavity of the first fixing shell is threadedly installed with a fixing tube, and the bottom end of the fixing tube is connected with the second fixing tube. The fixing shell is threadedly connected, and the bottom end of the fixing tube is threadedly connected to the inner wall of the bottom end of the first fixing shell, the outer surface of the fixing tube is fixedly installed with a magnetic force component, and the magnetic force component is composed of the first magnetic coil and the first magnetic force component. It consists of two magnetic coils. The present invention can change the injection speed of the solenoid valve of the nozzle of the urea dosing pump according to the change of the peak value of the exhaust gas of the vehicle.
Description
technical field [0001] The invention relates to the technical field of nozzle solenoid valves, in particular to a nozzle solenoid valve of a urea pump. Background technique [0002] With the rapid development of electromagnetic technology, solenoid valves are widely used, and different solenoid valves can be applied to different devices for opening. [0003] Since the state has made relevant requirements for the exhaust emission of diesel vehicles, a urea pump is installed near the exhaust pipe of diesel vehicles, and then urea solution is added to the urea pump to convert the exhaust gas discharged from diesel vehicles into pollution-free through the exhaust gas conversion device. Therefore, it is necessary to install a nozzle solenoid valve in the urea dosing pump to spray the urea solution in the urea dosing pump. [0004] In this regard, Chinese Patent Publication No.: CN107131345A discloses a solenoid valve for a urea pump nozzle, including a steel sleeve, a coil, a ma...
