Technical Field

[0001] The invention relates to the technical field of fuel filters, in particular to a sealable fuel filter for a fuel engine. Background Art

[0002] A fuel engine is a heat engine that converts the chemical energy of fuel into mechanical energy. The structure of a fuel engine consists of a body, a crank-connecting rod mechanism, a valve mechanism, a fuel supply system, a cooling system, a lubrication system, and a starting system. The fuel filter is an important component in the fuel engine system. Its function is to filter out harmful particles and moisture in the engine fuel system to protect the oil pump nozzle, cylinder liner, piston ring, etc., reduce wear and avoid clogging. Existing fuel filters usually include a housing and a filter element. A guide tube is provided inside the filter element. The fuel enters between the housing and the filter element, enters the filter element after being filtered by the filter element, and is discharged to the engine through the guide tube for use. Faults are unavoidable in the fuel system of a fuel engine, but it is difficult for existing fuel filters to quickly seal the fuel inlet, which makes subsequent fault inspection and repair inconvenient.

When the oil outlet needs to be sealed, the first gear 502 is rotated to an angle that meshes with the second gear 507 and moves it downward to the same horizontal plane as the second gear 507. At this time, rotating the first gear 502 drives the second gear 507 to rotate, and the rotation of the second gear 507 drives the threaded long rod 506 to rotate. When the threaded long rod 506 rotates, it drives the threaded long rod 506 that cooperates with it and is penetrated by the bottom thin rod 505 to limit the position. The sleeve plate 508 moves downward, and the threaded sleeve plate 508 moves down to the bottom of the circular sleeve shell 1, so that the oil outlet can be sealed.
