Electromagnetic pulse valve is submerged pulse jet bag filter cleaning system, compressed air "switch." Control pulse jet control device output signal, bag-by-row (room) injection cleaning, so dust pressure is maintained within the set range, in order to ensure the efficiency of the processing power and dust precipitator. Advantages: embedded in the seat air bag installation, low resistance, good liquidity, high injection volume, good operating results, stable performance, easy maintenance, long service life, improved load driven by volume, expanding the use of air pressure more suitable for low pressure gas source occasions. Connection: threaded cannula connection type submerged pulse valve diaphragm before and after the two chambers into the pulse valve, when on compressed air, compressed air flow through the hole into the gas chamber after, this time after the chamber pressure diaphragm close to the outlet valve, pulse valve is closed.
