Abstract

The invention discloses an automatic water draining device. The automatic water draining device comprises a valve body, an inner cylinder is arranged in the valve body and vertically arranged, the outer wall of the inner cylinder is covered with an annular coil rack, and a coil used for producing a magnetic field is wound on the coil rack; a sewer pipe is arranged on the upper portion of the valvebody, downwards stretches into the inner cylinder and communicates with the inner cylinder; and a spring jacking sealing structure and a magnetic adsorption water draining structure are arranged in the valve body. The invention further discloses a fuel filter which adopts the automatic water draining device and has an automatic water draining function and a using method thereof. According to theautomatic water draining device, the fuel filter using the automatic water draining device and the using method, water can be automatically drained in time, the condition that a water collecting cavity is filled with water is avoided, the service life of a filter element is prolonged, the condition that an engine is damaged due to the fact that fuel oil contains water is prevented, the using costof the fuel filter with the automatic water draining function and a motor vehicle is reduced, and the maintenance operation frequency is decreased.

Description

technical field [0001] The invention relates to the technical field of motor vehicle fuel filtration, in particular to an automatic drainage device and a fuel filter. Background technique [0002] The water contained in the fuel will destroy the oil film that plays a lubricating role in precision friction. The destruction of the lubricating oil film will cause the oil pump and other precision components to be in a state of dry friction or semi-dry friction, and even cause the fuel injection pump to fail. In addition, moisture can also promote the formation of microorganisms, and the pollutants produced by microorganisms will reduce the service life of the filter element and increase the replacement frequency of the filter element. [0003] First of all, end users have a deep understanding of engine failures caused by solid particles in fuel, but they are unaware of the damage caused by water in fuel to the engine, so they ignore the work of regularly draining the fuel filte...
