Pulse valve theory: the electromagnetic pulse valve vent hole in accordance with the signal control valve to open and close the cavity, the valve body unloading pressure gas emissions valve cavity pressure before the gas diaphragm the Yin pressure hole throttle, the diaphragm is lifted, the pulse valve injection. Body to stop the unloading, the pressure of gas through the orifice rapidly filled with the valve after the cavity, on both sides of the diaphragm by the difference of the force area on the body, the valve chamber, the gas force, the diaphragm can be reliably close valve vents the pulse valve to stop blowing. The signal is a millisecond timing pulse valve to open the moment, have a powerful impact air flow, in order to achieve an instant injection. 
 Straight-through pulse valve works: 
 TMF,-T (DFM-T) electromagnetic pulse valve for straight-through electromagnetic pulse valve, 180 ° angle between its import and export, usually with the air box pulse bag filter matching. Before the diaphragm to electromagnetic pulse valve into the chamber after two, when connected to compressed air, compressed air through the orifice into the chamber, then the chamber pressure diaphragm components close to the output port of the valve electromagnetic pulse valve in the "off" state. Pulse jet control device of electrical signals to the electromagnetic pulse valve armature moved bleed hole to open the chamber after the valve, the post-chamber rapid loss of pressure, the diaphragm assembly shifted blowing compressed air through the valve outlet, electromagnetic pulse valve in the "open" state. Pulse jet control device signals disappear, the electromagnetic pulse valve armature reset, after the chamber put stomatal closure and post-chamber pressure to the diaphragm assembly close to the output port of the valve, electromagnetic pulse valve in the "off" state. 
 Submerged pulse valve works: 
 Before the diaphragm to electromagnetic pulse valve into the chamber after two, when connected to compressed air, compressed air through the orifice into the chamber, then the chamber pressure diaphragm components close to the output port of the valve electromagnetic pulse valve in the "off" state. Pulse jet control device of electrical signals to the electromagnetic pulse valve armature moved bleed hole to open the chamber after the valve, the post-chamber rapid loss of pressure, the diaphragm assembly shifted blowing compressed air through the valve outlet, electromagnetic pulse valve in the "open" state. Pulse jet control device signals disappear, the electromagnetic pulse valve armature reset, after the chamber put stomatal closure and post-chamber pressure to the diaphragm assembly close to the output port of the valve, electromagnetic pulse valve in the "off" state. Electromagnetic pulse valve the DSF-Z electromagnetic pulse valve) at right angles to pulse valve angle of 90 degrees between its import and export, it applies to the cylinder and dust injection pipe installation and connection, air flow, can provide to meet the requirements of the pulse cleaning airflow. Electromagnetic pulse valve pulse bag dust clean blowing system of compressed air "switch". Subject to control of the instrument output signal control pulse jet bag-by-row (room) injection cleaning, remain within the limits set by the resistance of the dust collector to ensure that the processing power and collection efficiency of the precipitator.
