Exploded drawing of double flux solenoid valve From above diagrams, it is known that this kind of solenoid valve consists mainly of valve body, membrane, cone-shaped spring, valve cover, pilot valve, control valve of small flux, reposition valve, winding of pilot valve and small flux valve winding. The working principle of double flux solenoid valve can be leaned from Diagram 2-35. Pilot valve, small flux valve and main valve controlled by membrane are closed after power cut, no oil pass solenoid valve. When both two windings are open, pilot valve and small flux valve switch on, pressured oil pushing down membrane. Part of oil in A chamber flow toward outlet of sol fuel dispenser enoid valve via pilot valve and small flux valve, main valve is switched on after overcoming spring, at this state, solenoid valve is in large flux. When winding of pilot valve is cut power, pilot valve is closed, membrane go upward so as to close main valve due to oil pressure increase in A chamber. Solenoid valve is in small flux state. If the power of winding of small flux valve is cut off, small flux valve is closed, no flux in solenoid valve. It is learned from above introduction that the large and small flux of solenoid valve are controlled by pilot valve and small flux valve. This is why it called double flux solenoid valve. As filing motor, pilot valve, fuel dispenser small flux valve and main valve are switched on, fuel dispenser work in large flux state. When filling volume nearly reach presetting value, winding power of pilot valve is cut off, main valve is closed. However, small flux valve is still working. When filling volume reach preset-value, the winding power of small flux valve is cut off, solenoid valve is closed. Filling operation is end. Troubleshooting In filing operation some troubles maybe correlate to solenoid valve, some maybe to other hydraulic components. Small flux or no delivery in fuel dispenser, for example, it is possible caused by solenoid valve or other components. Therefore, it is need to give concrete analysis and diagno fuel dispenser
