QD - Z - 20 / 25 Series Electromagnetic Pulse Vave GOYEN Replace Right Angle Air Dust Proof Valve 3 / 4 " , 1 "
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 thebaghouse within the set range and thus guarantee the processing functions and the dust collecting efficiency of the baghouse .
Z type electromagnetic pulse valves is a right angle valve , with the 90 degree , angle between the inlet and outlet , which is suitable for the installation connection between the gas dome and the baghouse blow tube provide good air flow and dust clean pulses satisfying the requirements .
Working Principle
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 .
Material Construction
| Body | ADC12 die cast |
| Armature | 430FR stainless steel |
| Diaphragm | Nitrile or viton |
| Spring | 321 Stainless steel |
| Fasteners | 302 Stainless steel |
Good Quality membranes shall be selected and used fo all the valves , with each part checked in each manufacturing procedure , and put into the assembly ling conforming to all the procedures . Every finished valve shall be taken the electriferous blowing test .
Common failure and troubleshooting
| 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. |
