1.Product introduction：
The DCF-T model is a straight-through type pulse valve, with the center line of the inlet and outlet on the same straight line. The inlet is connected to the air manifold, and the outlet is connected to the blow pipe. The straight-through pulse valve has a large air chamber, a large air blowing volume, convenient installation, and good cleaning effect.
2. Working principle:
The pulse valve consists of an solenoid post, a diaphragm, and a valve body. The area of the rear chamber of the diaphragm is larger than that of the front chamber, and the pressure force is large, causing the diaphragm to be in the closed position.
The pulse controller inputs an electrical signal, causing the solenoid post to engage the moving column, open the unloading hole, and quickly discharge the pressure gas in the rear chamber of the diaphragm. The pressure gas in the front chamber of the diaphragm lifts the diaphragm, opens the channel, and the pulse valve blows.
The electric pulse signal disappears, and the spring of the solenoid post immediately resets the moving column to close the unloading hole. The gas pressure and spring force in the rear chamber of the diaphragm close the channel, and the valve stops blowing.
The damping hole on the diaphragm plays a role in damping the airflow when the pilot head moves the column to lift the gas pressure for unloading. When the unloading hole is closed, the pressure gas quickly fills the rear chamber, causing the diaphragm to close the channel and stop blowing.
3. Structural characteristics：
The pilot control device of the straight-through type pulse valve adopts a magnetic material with extremely low carbon content, which has undergone vacuum magnetic treatment to eliminate impurities, enhance magnetic induction strength and permeability, and make the magnetic yoke iron move sensitively and reliably.
The orifice and unloading hole on the straight-through pulse valve are matched with the pulse valve chamber, and the optimal value is obtained through experiments. This ensures that the electric through magnetic pulse valve has a greater impact force and faster switching performance during cleaning, and maximizes the lifting height of the diaphragm, thereby increasing the cleaning amount per unit time of the pulse valve.
Diaphragm: High performance imported diaphragm is selected to ensure the long-term reliable operation of the pulse valve.
Advanced manufacturing equipment and testing instruments are used to ensure the quality of springs (such as spring composition analysis analyzers).
