In the figure: 1. a base; 2. a seal ring; 3. an exhaust knob; 4. an oil outlet channel; 5. rotationally installing a clamping sleeve; 6. a filter tank; 7. an oil-water separation sensor; 8. a water drain valve; 9. a hand pump; 10. an oil inlet channel; 11. a filter element; 12. a flow guide pipe; 13. an upper end cover of the filter element; 14. sealing the plate end cover; 15. a one-way valve.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the utility model provides a fuel filter for a light automobile, which comprises a base 1, a sealing ring 2, an exhaust knob 3, an oil outlet passage 4, a spin-on ferrule 5, a filter tank 6, an oil-water separation sensor 7, a water drain valve 8, a hand pump 9, an oil inlet passage 10, a filter element 11, a flow guide pipe 12, a filter element upper end cover 13, a sealing plate end cover 14 and a one-way valve 15, wherein the hand pump 9, the oil inlet passage 10, the oil outlet passage 4 and the one-way valve 15 are arranged on the base 1, and the sealing plate end cover 14 is arranged in the base 1; a plunger cavity is arranged in the hand pump 9, a check valve 15 is arranged on the oil outlet channel 4, the check valve 15 is communicated with the exhaust knob 3, and the exhaust knob 3 is connected with the oil outlet channel 4 through threads; the filter tank 6 is fastened with the base 1 through the screw threads of the screw clamping sleeve 5, and the filter element 11 is arranged in the filter tank 6 and can be detached, so that the filter tank is more convenient to maintain and more environment-friendly and has lower cost; when the hand pump 9 pumps oil, fuel oil enters the filter element 11 through the oil inlet channel 10, the filtered fuel oil enters the bottom of the filter tank 6, passes through the guide pipe 12 and is sucked into the plunger cavity of the hand pump 9, and then is discharged from the exhaust knob 3 through the check valve 15 on the right side of the cavity or enters the oil outlet channel 4.
The one-way valve 15 adopts an umbrella-shaped diaphragm.
The hand pump 9 adopts a plunger type structure, so that the oil pumping quantity can be increased, and the exhaust time can be shortened.
