Background
The fuel filter is arranged on the engine or the whole vehicle and is used for filtering impurities in diesel oil and protecting precision parts such as a high-pressure oil pump, an oil sprayer and the like. Besides impurities, the diesel oil also contains water, and the damage to a fuel system is large, so that the rusting and the clamping stagnation of the plunger can be even caused in serious conditions. Therefore, how to timely and accurately drain the moisture in the filter and prevent air from entering the filter and the fuel system plays an important role in protecting the normal operation of the whole fuel system.
At present, most of water filtered by the fuel oil coarse filter is stored in a water collecting cup at the bottom of the filter (the density of water is greater than that of oil), the liquid level height of the accumulated water in the water cup is detected through a liquid level sensor arranged in the water cup, and after a detection result is sent to an ECU (electronic control unit) for identification, the ECU prompts a driver to discharge water in a mode of driving an indicator lamp on an instrument panel. The driver sees to remind the back and discharges the water through the manual operation of the integrated switch that drains in filter bottom, but this kind of structure is not only loaded down with trivial details and because there is oil with water in the ponding cup, oil floats on the top of water, and oil will discharge out along with it after water is put, therefore the driver need judge when water soon will be put to end and in time close the switch that drains, therefore it is necessary that the valve that drains improves.
