The DMF-T straight through electromagnetic pulse valve is a right angle valve with an inlet and outlet angle of 180 degrees. It is suitable for the installation and connection of the gas storage cylinder and the dust removal spray pipe, with smooth airflow and the ability to provide pulse cleaning airflow that meets the requirements. DMF-T straight through electromagnetic pulse valve is matched with air box pulse bag filter.

The working principle of DMF-T straight through electromagnetic pulse valve:

The diaphragm divides the electromagnetic pulse valve into two chambers, front and rear. When compressed air is connected, it enters the rear chamber through the throttle hole. At this time, the pressure in the rear chamber presses the diaphragm component tightly against the output port of the valve, and the electromagnetic pulse valve is in the "closed" state.

The electrical signal of the pulse jet control device causes the electromagnetic pulse valve armature to move backwards, the vent hole in the rear chamber of the valve opens, the rear chamber rapidly loses pressure, the diaphragm component moves backwards, compressed air is blown through the valve output port, and the electromagnetic pulse valve is in the "open" state.

The electrical signal of the pulse jet controller disappears, the electromagnetic pulse valve armature resets, the rear chamber vent hole closes, and the pressure in the rear chamber increases, causing the diaphragm component to tightly adhere to the output port of the valve. The electromagnetic pulse valve is then in the "closed" state.

Common faults of DMF-T straight through electromagnetic pulse valve during use

The DMF-T straight through electromagnetic pulse valve plays a significant role in bag filters, serving as the "switch" for the spray air path of the pulse bag filter cleaning system. It is controlled by an electrical controller to perform pulsating "impulse" spray cleaning. High quality electromagnetic pulse valves are necessary to ensure the normal operation of bag filters.

1. The electromagnetic pulse valve inputs an electrical signal, but the pilot head does not move, the diaphragm does not move, and the valve does not work. --The line is not connected; Voltage too low; Due to improper installation on site, the pilot head's moving column got stuck.

2. The electromagnetic pulse valve inputs an electrical signal, and the pilot head's moving column jumps in place. The pulse valve cannot perform spraying, and the unloading hole is blocked and the exhaust is not smooth. The pilot head's moving column is stuck.

3. The electromagnetic pulse valve inputs an electrical signal, causing the diaphragm to bounce in place and preventing the pulse valve from blowing. --The pilot head's moving column is jumping, and the wear of the large diaphragm damping hole increases, resulting in a decrease in damping effect; The small diaphragm damping hole is blocked, and the unloading exhaust is not smooth.

4. The electrical signal of the electromagnetic pulse valve disappears, and the pilot head cannot reset. --There are burrs or impurities that cause the moving column to get stuck; Spring fatigue and insufficient elasticity; The damping hole is blocked, and the pressure gas cannot pass through or the pressure is low.

5. The electrical signal of the electromagnetic pulse valve disappears, and the diaphragm cannot be reset and closed. --The damping hole is blocked, the damping effect is too strong, and the pressure gas cannot be delivered in time; Low static pressure; The unloading hole is not closed in a timely manner.

6. The electrical signal of the electromagnetic pulse valve disappears, and the diaphragm cannot be reset and closed. --Damping hole blocked; The unloading hole is not closed.

7. The pilot valve coil heats up, burns out, and has high voltage; --Specify DC24V voltage, input AC220V voltage to cause excessive current.

8. At pressures above 0.5 MPa, the diaphragm cannot be opened. --The wear of the damping hole increases.

9. At pressures below 0.4 MPa, the diaphragm cannot be closed. --The damping hole is blocked; The static pressure decreases.

10. Input electrical signal, the diaphragm cannot be opened, and the valve cannot be blown. --The pilot valve is not working; The small diaphragm damping hole and unloading hole are blocked.

11. In any state, the valve cannot be closed and ventilation continues. --The inlet and outlet directions of the valve may be reversed.
