Embodiment Construction
[0009] The present invention will be described in further detail below with reference to the drawings and embodiments.
[0010] refer to figure 1 , figure 2 It can be known that the present invention is applied to the diesel filter element end cap of the diesel oil filter, including the end cap body 1, the material of the end cap body 1 is plastic, and the peripheral wall of the end cap body 1 has an upward protrusion 15, where the protrusion 15 is provided with diversion holes 2 (several), and the upper end of the protrusion 15 is provided with a concave groove 4 (for placing the first inner seal 3 of the diesel filter). The material of the end cap body 1 is engineering plastics, such as engineering plastics nylon 66 (but not limited), as long as it meets the mechanical performance requirements of the filter.
[0011] refer to image 3 It can be seen that the diesel oil filter element end cap of the present invention is applied to a diesel oil filter, and the diesel oil f...

The invention discloses a diesel filter element end cover applied to a diesel filter. The diesel filter element end cover comprises an end cover body (1), the end cover body is made of plastic materials, an upward protrusion (15) is arranged on the peripheral wall of the end cover body, flow guide holes (2) are formed in the protrusion, and a concave groove (4) is formed in the upper end of the protrusion. When diesel passes through the flow guide holes in the end cover body to be guided, the small flow guide holes achieve the function of 'capillary tubes', due to the fact that the proportion of oil and the proportion of water is different, the eccentricity of the oil in the diesel and the eccentricity of the water in the diesel are different when the oil and the water in the diesel pass through the flow guide holes, therefore, emulsification water in the diesel is separated into free water, due to the fact that the free degree of the free water is larger than that of the emulsification water, the free water can be automatically separated, and therefore the overall oil-water separation efficiency of the filter is improved, the service life of the filter is prolonged, and the product quality of the filter is improved.
Description
technical field [0001] The invention relates to a vehicle filter, in particular to a filter element end cover of a diesel filter. Background technique [0002] At present, the filter element assembly of a diesel filter includes filter paper, a central tube, and an end cover. The end cover is made of ordinary iron material without special structural design, and can only support the filter paper in the filter element assembly, not Equipped with oil-water separation function for diesel. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and provide a diesel filter element end cover which can not only support the filter paper in the filter element assembly but also have the function of separating oil and water. [0004] The purpose of the present invention is achieved through the following technical solutions: the end cap of the diesel filter element includes an end cap body, the material of the end cap body is plas...
