DMF-Z-25 G1'' Diaphragm Pulse Electric Valve For Filter Dust Voltage AC110V/AC220V/DC24V/12VDC
DMF-Z-25 Diaphragm Pulse solenoid valves, used in such as cement plants, as automatic control components in automatic dust removal equipments.
The working principle is that the high-pressure gas is connected from the air inlet and enters the lower air chamber.
1. When the pulse valve is not energized, the gas enters the decompression chamber through the constant pressure pipe of the upper and lower casings and the throttle hole therein, due to the valve. The core blocks the pressure relief hole under the action of the spring, the gas is not discharged, and the pressure of the decompression chamber and the lower air chamber are uniform, and under the action of the spring, the diaphragm blocks the blowing port, and the gas does not rush out.
2. When the pulse valve is energized, the valve core is lifted up by the electromagnetic force, the pressure relief hole is opened, and the gas is ejected. Due to the action of the constant pressure pipe orifice, the outflow speed of the pressure relief hole is greater than that of the decompression chamber. The inflow velocity of the pressure tube gas causes the pressure in the decompression chamber to be lower than the pressure in the lower chamber, and the gas in the lower chamber elevates the diaphragm, opens the nozzle, and performs gas injection.

Common faults and repair methods of DMF-Z-25 membrane pulse solenoid valve:
1. The spring is damaged. The spring on the pulse valve spool is easily damaged. The appearance is that the pulse valve is deflated to the blow port for a long time. The treatment method is to replace the spring.
2. the valve core dirt, because the intake air is not clean, causing the fouling of the valve core, resulting in the appearance of long-term intake of the nozzle or the pulse valve does not work after the power, the treatment method is to clean the valve core.
3. the diaphragm is damaged, after long-term work, the diaphragm is easy to fatigue, oxidation, etc., resulting in the appearance of long-term deflation of the pressure relief port, the pulse valve does not work, the treatment is to replace the diaphragm.
4. The rubber pad is damaged. After the use time is long, the rubber pad on the pulse valve spool is easily damaged. The appearance is that the pulse valve is deflated to the blowing port for a long time. The treatment method is to replace the rubber pad.
5. The orifice is blocked or damaged. The intake air is not clean and the throttle hole is blocked. The appearance is that the pulse valve is deflated to the nozzle for a long time. The treatment method is to clean the orifice; the orifice is damaged or missing, and the orifice is made. Loss of interception, resulting in abnormal pressure relief, the appearance of the pulse valve after the power is activated, the pressure relief port deflation, but the pulse valve is not sprayed, the treatment is a replacement orifice.
