The structure of the fuel filter includes the following parts: 1-Sealing gasket, 2-Connecting plate, 21-Oil inlet, 22-Filter seat connection hole, 3-Sealing ring, 4-Top cover, 5-Valve seat, 51-Oil outlet, 52-annular flange, 6-valve sleeve, 7-return spring, 8-gasket, 9-valve plate, 10-filter paper, 11-center tube, 12-bottom end cover, 13- Support spring, 14-filter housing, 15-gland.
The fuel filter includes: a filter housing, a filter element is installed in the filter housing, the filter element includes filter paper, a top end cover, a bottom end cover and a central tube, and the filter paper surrounds the outer peripheral surface of the central tube , the top end cover and the bottom end cover are located at both ends of the filter paper; it is characterized in that the top end cover is connected to a valve seat, and the valve seat extends into the central tube and has an oil outlet. A one-way valve is installed at the oil outlet of the valve seat.
1. An annular convex ring is provided along the periphery of the oil outlet of the valve seat.
2. The one-way valve includes a valve sleeve, which is fixedly connected to the valve seat. A valve piece and a return spring are provided in the valve sleeve. Under the action of the return spring, the valve piece The annular convex ring abuts against the oil outlet of the valve seat.
3. A gasket is provided between the valve plate and the return spring.
1. There is a filter element installed in the filter housing. The filter element includes filter paper, top cover, bottom end cover and central tube. The filter paper surrounds the outer circumference of the central tube. The top cover and bottom cover are located at both ends of the filter paper; the top cover is connected with a valve. The valve seat extends into the center pipe and has an oil outlet. A one-way valve is installed at the oil outlet of the valve seat. When the engine is running, the fuel filter works normally; after the engine is shut down, the one-way valve Under the action of the valve, the oil outlet on the valve seat is closed, preventing the pipeline connected to the fuel filter and the fuel return inside the fuel filter, so that the inside of the fuel filter and fuel pipeline will not be affected by the presence of air. The formation of an air cavity leads to insufficient fuel supply, thereby avoiding the difficulty in starting due to insufficient fuel supply when the engine is started again.
2. An annular convex ring is provided along the periphery of the oil outlet of the valve seat, which can better fix the one-way valve and make the one-way valve function better.
