Gas chamber A2 before entering, 1, when the electromagnetic coil A3 of electromagnetic impulse valve is powered, armature component A4 is lifted up under electromagnetic force,
Relief hole A5 is opened, gas discharge, and due to the throttling action of diaphragm throttle orifice A6, the gas flow of relief hole outflow is greater than warp knuckle
Inflow from discharge orifice to rear gas chamber's A7 gas gas flow, enable rear gas chamber's pressure be lower than preceding gas chamber pressure, the gas of lower chamber
Pressure jacks up diaphragm A8, opens the blowing mouth of pulse gas outlet, carries out Gas injection.2, when the electromagnetic wire of electromagnetic impulse valve
When circle is without electricity, gas enters rear gas chamber by the throttle orifice in the diaphragm between upper and lower two housings, since armature component is in bullet
Relief hole is blocked under the action of spring, gas will not be discharged, enable rear gas chamber consistent with the pressure of lower chamber, diaphragm and in big spring and
Under upper lower chamber difference compression area effect, high pressure gas no longer sprays, and forms pulsatile once gas.
The problem of existing pulse valve will appear when in use:
1, since throttle orifice smaller (Φ 1.5 or so) can cause preceding gas chamber gas backward because of the blocking of the pollutants such as dust
The influx of room gas is reduced, and gas chamber is supplied gas to rear gas chamber before causing, and the time is elongated, and pulse gas is exported the mouthpiece of spray by diaphragm
It is not agile to block, and causing impulse waveform to slow down causes the dust removing effects of deduster to decline；
2, since gas chamber is supplied gas to rear gas chamber before making, the time is elongated, and the delay that diaphragm is closed has a large amount of high pressure gas from arteries and veins
Gas vent evolution is rushed, the energy is wasted；
3, diaphragm the washing away because of high pressure gas of throttle orifice has been opened, Cracking Failure is easy.
