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 sol fuel dispenser enoid 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 solenoid 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 soleno fuel dispenser id valve are controlled by pilot valve and small flux valve. This is why it called double flux solenoid valve. As filing motor, pilot valve, 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

dent provider of blogging tools and hosting services. Ms Trott is Six Apart s president and public face, while Mr Trott, who is shy and retiring, runs the technical side of things and seasoned executives handle the management. Six Apart s flagship products, Movable Type and TypePad, are popular among “power bloggers�with large audiences, and its third product, LiveJournal, is big among teenage girls who blog for their friends. Collectively, Six Apart s products are used by over 30m blogge fuel dispenser rs around the world. These days, however, the Trotts are most excited about their newest product, Vox, which was launched last month. For if a blogging service can have a personality, then Vox has Ms Trott s. Like Ms Trott, Vox is unpretentious and accessible. By contrast with rival services, users need not worry about having to understand technical matters, such as the HTML formatting language in which web pages are encoded, in order to incorporate whizzy features into their blogs. They can upload pictures, video clips and songs with just a few clicks on a simple, colour-coded page. Also like Ms Trott, Vox celebrates the frivolous and mundane. Much of Ms Trott s personal blog, VoxTrott, is fuel dispenser devoted to images of her beloved dog Maddy, while Mr Trott, a dilettante cook, likes to post “disgusting pictures of good food�on his blog. Many ordinary people are scared of blogging because they feel that they have nothing to say, says Ms Trott. So her message is that “mundane is interesting; it s OK to talk about your sandwich� To a handful of people in the world it may mean a lot. The other thing that keeps many people from blogging is fear for their privacy, she thinks. Hence the third and most important characteristic of Vox. It is intimate. For every item on Vox—a text paragraph, a photo, a link—bloggers can determine if it is to be public or private and, if it is private, exactly who can see it. Ms Trott, for instance, keeps one part of VoxTrott for communicating only with her mother, who ha fuel dispenser
