Usage                                                                                                                                                                                                                

 

Electromagnetic valve ( Also called diaphragm valve ) is the” switch “for compressed air in the dust clean blowing system of the pulse bag filter . Controlled by the output signals of the pulse jet control device , it makes dust clean to the filter bags cell by cell to keep the resistance of the baghouse within the set range and thus guarantee the processing functions and the dust collecting efficiency of the baghouse .

 

Y type electromagnetic pulse valves is a suble for the work occasions embedded valve ) , is directly installed in the gas bag , with better flow characteristics . As pressure losses drops , it will be suitable for the work occasion of loser pressure gas source .

 

Working Principle                                                                                                                                                                                              

 

The electromagnetic pulse diaphragm valve is composed of two gas cells . When the compressed air is connected , it comes into the back bags cell though the orifice , the pressure in the back gas cell pushes the diaphragm against the outlet of the valve and the electromagnetic valve stays in the “ closed ” condition .

 

When the electromagnetic pulse valve returns to its original position .

The air escape of the back gas cell closes and the pressure in the back gas cell cell rises , which pushes the diaphragm closely again .

 

The electrical signals from the pulse jet control device move the armature of the electromagnetic pulse valve . The air escape of the back gas cell opens and the back bag gas cell loses pressure quickly , thus the diaphragm moves back and the compressed air blows through the valve outlet . The electromagnetic pulse valve comes into the “ open ” condition .

 

Pulse valve is composed of pilot head, diaphragm and valve aluminum body. The back cavity area of diaphragm is bigger than the front one. The diaphragm is kept at the closed position due to the effect of big pressure.
Electrical pulse controller send input signals so that the electromagnetic armature attracts the moving bar. Unclose the balancing hole to release the pressure gas in the back cavity of diaphragm quickly; the pressure gas in the front cavity holds up the diaphragm to open the passage and the valve starts cleaning.
The pulse signal disappears and the spring of the armature works immediately to resume the moving bar so as to close the balancing hole. The pressure gas in the back cavity of the diaphragm and the spring work together to close the passage the valve stops cleaning.
The damping hole in the diaphragm functions to damp the airflow when the moving bar of armature holds up for balancing and to transit the air to the back cavity as soon as the balancing hole is shut to close the passage and stop cleaning.

Use period
Failure phenomena
Possible Reason
Troubleshooting
During installation and commissioning
The valves cannot all be opened, but the leading part does act.
Check the gas dome pressure to see if it is too low.
Check the leakage
Some valves do not work, but the others are normal.
Check the valve coil connection and coil
Replace the accessories
The valves cannot all be closed. There is leakage. There is no way to establish a gas dome.
Y-valve. Some valves for the same gas dome are leaking, thus causing leakage for all the valves.
Check the leakage
Z-valve. The valve inlet and blowing muzzle are installed backwards.
Re-install
Some valves cannot be closed. There is leakage.
There is some dirt or debris on the membrane, ii is blocking the moving iron core.
Clean the membrane and check that the membrane is complete. Check the moving iron core and air lock.
A valve closing is slowly.
The membrane orifice is blocked.
Dredge the membrane orifice
During use period
Some valves are leaking. The membrane cannot close tightly and the valve is always open a
little.
There is some dirt or debris on the membrane, the leading part is damaged. Moving iron core is blocked.
Clean the membrane and check that the membrane piece is complete. Check the moving iron core and the air lock. Replace the accessories if necessary.
Coil is hot and burned out.
It has been turned on for too long.
Check the working condition of the control system.
Voltage exists but the valve does not operate.
Membrane is damaged and the orifice is blocked.
Replace the accessories in time.
Ambient temperature is below -20℃. The valve is leaking and cannot open.
Ambient temperature is too low and here is frost in the valve.
Pay attention to insulation and maintaining proper temperatures.
