Embodiment Construction

[0028] Such as figure 1 with figure 2 As shown, the fuel filter includes a fuel filter seat 1 , a fuel filter element 3 and a water cup 5 . The fuel filter element 3 is a rotary filter element, and the water cup 5 is an embodiment of a water collecting container. The fuel filter element 3 is connected to the bottom of the fuel filter seat 1, and the water cup 5 is connected to the bottom of the fuel filter element 3. Fuel enters from the fuel inlet 7 of the fuel filter seat 1, flows into the fuel filter element 3, and flows out from the fuel outlet 8 after being filtered. Impurities are retained on the filter material 31 of the fuel filter element 3, while the water sinks into the bottom of the filter or the special water cup 5 under the gravity of the water itself after being intercepted.

[0029] Such as Figure 1 to Figure 3 As shown, a solenoid valve 51 is installed in the water outlet at the bottom of the water cup 5, once the solenoid valve 51 is opened, the water i...

Abstract

The invention aims to provide a fuel filter integrating an automatic water drain valve, so as to solve the problem of inconvenient water drainage of an existing fuel filter. The fuel filter integrating the automatic water drain value aiming to achieve the purpose comprises a filter element and a water collection container which is arranged below the filter element, and is characterized by consisting of an electromagnetic valve, a controller and a water sensing unit; the electromagnetic valve is arranged in an outfall at the bottom of the water collection container; the water sensing unit detects a water signal; the water signal is transmitted to the controller; and the controller controls a current signal to the electromagnetic valve according to the water signal, so as to start the electromagnetic valve.

Description

technical field [0001] The present invention relates to fuel filters. Background technique [0002] Water in fuel is a common phenomenon because water can enter the fuel tank in a car's fuel system in a number of ways. Most of the water in fuel oil comes from the poor treatment process of the refinery itself and the mixing of rainwater during transportation and storage. There is usually a filling port on the fuel storage device, but people often forget to add a cap on it; without the cap, rainwater can also flow from the filling port into the storage device. [0003] When fuel contains water and gets into your car's fuel system, it can cause problems such as: [0004] 1. Promote the corrosion of iron parts and aluminum parts in the fuel injection system; [0005] 2. Cause cavitation and lead to the failure of the top of the nozzle; [0006] 3. Reduce the lubricating performance of fuel, resulting in wear of nozzles and pump plungers; [0007] 4. Nourishing the microorga...
