Description
Electro magnetic solenoid valve(also called diaphragm valve) is the "switch" for compressed air in the dust clean blowingsystem of the pulse bag filter. Controlled by the output signals of the pulse jet control device. It makes dust clean to the filter bags cell by cell to keep the resistance of the baghouse within the set range and thus guarantee the processing functions and the dust-conliecting efficiency of the baghouse.
AMF electro magnetic pulse valves is a right-angle valve, with the90° angle between the inlet and outlet, which is suitable for the installation connection between the gas dome and the baghouse blow tube to provide good air flow and dust clean pulse satisfying the requirements.
Working Principle:
The electro magnetic pulse diaphragm valve is composed of two gas cells. When the compressed air is connected , it comes into the back gas cell though the orifice, the pressure in the back gas cell pushes the diaphragm closely against the outlet of the valve and the electro magnetic valve stays in the closed condition.
The electrical signals from the pulse jet control device move the armature of the electro magnetic pulse valve. The air escape of the back gas cell opens and the back gas cell loses pressure quickly, thus the diaphragm moues back and the compressed air blows though the valve outlet. The electro magnetic pulse valve comes into the open condition.
When the electrical signals from the pulse jet control device disappear, the armature of the electro magnetic pulse valve return to its original position. The air escape of the back gas cell closes and the pressure in the back gas cell rise, which pushes the diaphragm closely against the valve outlet. The electro magnetic valve comes into its closed condition again.
Installation Method:
Solenoid pulse valve input is connected to the metal pipe of air storage cylinder, and its oytput is connected to the blast pipe of the dust pocket. Between the connect screw thread is filled with tetrafluoroethylene tape for seal.
