Principle of cylinder poppet valve of bag dust collector

The bag dust collector is designed to work under negative pressure. Under this condition, to isolate a filter chamber (make a filter chamber offline), you only need to close the offline poppet valve. During offline cleaning, this valve is closed. The opening and closing power of the poppet valve is provided by a double-acting cylinder and is controlled by a single electric controlSolenoid valve control.



The position of the poppet valve is controlled and displayed by the travel limit switch. When the single chamber is maintained offline when the dust collector is working, personnel must close the lift valve, close the solenoid valve and the ball valve before entering the filter chamber, and at the same time close the manual regulating valve at the air inlet of the ash hopper before opening the upper top cover. Perform maintenance.



In the bag dust collector, the opening and closing of the cylinder poppet valve is controlled by dust cleaning or filtration. When the bag dust collector is filtering and removing dust normally, the cylinder is in the open state;cleaning When the bag is dusty, the cylinder lift valve closes, cutting off the passage of smoke from the bag chamber to the air outlet.



Relevant safety regulations should be followed when using the cylinder poppet valve. When a failure occurs, there should be an emergency stop device. After the work is completed, the compressed air inside the cylinder should be discharged.



The bag dust collector cylinder lift valve coil controls the air path, and generally has a normally closed type and a normally open type. The normally closed type means that the air circuit is open when the coil is not energized, and the normally open type means that the air circuit is open when the coil is not energized.

In the bag dust collector, the opening and closing of the bag dust collector poppet valve is controlled by dust cleaning or filtration. When the bag dust collector is filtering and removing dust normally, the cylinder is in an open state. ;When cleaning, the cylinder lift valve closes, cutting off the passage of bag chamber smoke to the air outlet. The bag dust collector cylinder lift valve air pipe connection method is to use the cylinder to CylinderSeries connection up, controlled by a 3-position 5-way valve to open and close.
