Pulsed solenoid valve solenoid valve body coil input wire to the positive pulse signal generated by the coil flux, moving core pull, open the valve. When the positive pulse signal input is stopped, the moving core release, moving core back to the initial state under the action of spring force, and close the valve 
 Addition, there are able to maintain self-holding type, stop the importation of a positive pulse or power failure, you need to input a negative pulse signal can be reset; the main principle of the pulsed solenoid valve is like a kind of automatic water-saving taps, you click The water will come out after a while, the water will automatically shut down, pulsed solenoid valve is connect you, the valve will open, open, you can adjust their own, and then when the time comes, to turn itself off. 
 Pulsed solenoid valve works is the use of electrical pulses into mechanical pulse of the powerful energy of the pulsating gas into the release of momentum in a short time a huge momentum with the accumulation of dust in the filter surface, dust collector efficiency and resistance are corresponding increase in the media on both sides of the pressure difference is large, will some have been attached on the filter small particles squeeze past precipitator efficiency decreased. In addition, the resistance is too high dust precipitator system air volume decreased significantly. Therefore, the the precipitator resistance reaches a certain value to cleaning. Cleaning can not be destroyed early layer in order to avoid efficiency 

 Magnetic pulse valve use of environment and selection time: 
 In the selection of the electromagnetic pulse valve, the output voltage can reach the request, have a greater impact on the cleaning effect of the pulse valve, the output voltage can reach the request in the selection of the electromagnetic pulse valve pulse valve clearance gray effect has great influence, therefore, the selection of the control device, in particular, DC24V control device, conclude whether the controller to send enough voltage and current is very important stop parsing now divided into two conditions: 
 A high-power tube output of the controller output voltage at both ends of the electromagnetic pulse valve controller output voltage and high power tube to a pressure drop, so the analysis of the control circuit design parameters, and conclude whether side to get the chaos of DC 24V is very important. 
 2, the relay output control device of the controller due to the voltage output through the relay contacts, there is no pressure drop, it is the only controller power departments to design fair and reach normal output is not the purpose. 
 The use of environment a prerequisite of the electromagnetic pulse valve 
 Electromagnetic pulse valve after midnight in the use of the environment before the premise is very important, which relates to the electromagnetic pulse valve can not be normal and stable operation down. Electromagnetic pulse valve environmental premise: 
 An environment of high relative humidity and a drop of water and rain and other places, should be selected water solenoid valve. 
 Should be based on the rated power capacity of current and power-consuming. It should be noted that the higher VA value of the start of the exchange should be in the capacity of the lack of preference for the indirect electromagnetic valve. 
 3 according to the power supply varieties were selected to AC and DC solenoid valves. Common for the AC power to facilitate access. 
 Safe sex in the use of corrosive or explosive environments should be a priority basis to request the selection of resistance to hair loss. 
 5 environmental space is restricted, please use the multi-function solenoid valve, which eliminates the need for bypass and three manual valves and easy online service.
