Right Angle Pneumatic Pulse Valve , Electromagnetic Pulse Valve QD-Z-20 / 25 Serie SBFEC Type

 

 


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.

 

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.

 


Common failure and troubleshooting                                                                                                             

 

During installation and commissioning

 

Failure phenomena

 

1 . The valves cannot all be opened, but the leading part does act.

2 . Some valves do not work, but the others are normal.

3 . The valves cannot all be closed. There is leakage. There is no way to establish a gas dome.

4 . Some valves cannot be closed. There is leakage.

5 . A valve closing is slowly.

 

Possible Reason

 

1 . Check the gas dome pressure to see if it is too low.

2 . Check the valve coil connection and coil

3 ( 1 ) . Y-valve. Some valves for the same gas dome are leaking, thus causing leakage for all the valves.

3 ( 2 ) . Z-valve. The valve inlet and blowing muzzle are installed backwards.

4 . There is some dirt or debris on the membrane, ii is blocking the moving iron core.

5 . The membrane orifice is blocked.

 

Troubleshooting

 

1 . Check the leakage

2 . Replace the accessories

3 ( 1 ) . Check the leakage

3 ( 2 ) . Re-install

4 . Clean the membrane and check that the membrane is complete. Check the moving iron core and air lock.

5 . Dredge the membrane orifice

 

 

During use period

 

Failure phenomena

 

1 . Some valves are leaking. The membrane cannot close tightly and the valve is always open a

little.

2 . Coil is hot and burned out.

3 . Voltage exists but the valve does not operate.

4 . Ambient temperature is below -20℃. The valve is leaking and cannot open.

 

Possible Reason

 

1 . There is some dirt or debris on the membrane, the leading part is damaged. Moving iron core is blocked.

2 . It has been turned on for too long.

3 . Membrane is damaged and the orifice is blocked.

4 . Ambient temperature is too low and here is frost in the valve.

 

Troubleshooting

 

1 . 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.

2 . Check the working condition of the control system.

3 . Replace the accessories in time.

4 . Pay attention to insulation and maintaining proper temperatures.
