Abstract

The invention discloses a fuel filter automatic drain valve with an operating state self-detection function. The fuel filter automatic drain valve with the operating state self-detection function comprises a valve body, an electromagnetic valve and a controller, wherein the valve body is fixedly connected with the electromagnetic valve and the controller is connected with the valve body and the electromagnetic valve in an electric mode. The fuel filter automatic drain valve with the operating state self-detection function is capable of automatically detecting water level conditions of water in a fuel filter, achieving automatic drainage when the water level surpasses a limiting value, and automatically and intelligently controlling water drainage time. Therefore, damage to a vehicle due to the fact that water can not be drained in time manually is avoided, fuel is prevented from being drained mistakenly due to long-time water drainage, waste of the fuel is avoided, troubles caused by manual operation are eliminated, a user is prevented from carrying out water drainage operation in a narrow and small space, and intellectualization of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of fuel filtration and purification, in particular to a drain valve used for a fuel filter, which can realize automatic opening and closing, and can automatically detect the working state, and feed back the working state to the vehicle powertrain controller , with diagnostic functions. Background technique [0002] The fuel system of vehicles and ships needs clean fuel, so as to ensure the normal operation of the power system, and the fuel filter is produced under such a demand. [0003] The main function of the fuel filter is to filter out particulate impurities and water in the fuel. At present, the known oil-water separation devices for fuel filters mainly include the following two types: [0004] 1. It is completely necessary to manually check the amount of accumulated water in the filter and manually discharge the accumulated water; [0005] 2. It can automatically detect the amount of accumulated water in the ...
