Abstract
The utility model discloses a fuel filter which comprises a filter body and a filter element. An outer cavity is formed by the outer wall of the filter element and the inner wall of the filter body, a water outlet is formed in the filter body, an insertion groove which encircles the water outlet is formed in the filter body, a floating body is arranged in the cavity, the density of the floating body ranges from the density of fuel to the density of water, the floating body is connected with a control cover by a connecting rod, legs of the control cover are slidably connected with the insertion groove, and a plurality of through holes are formed in the legs of the control cover. The fuel filter has the advantages that the water in the fuel can be effectively filtered out, accordingly, various components can be prevented from being rusted by the water, and the fuel filter is simple in structure.
Description
Technical field
The utility model relates to a kind of filter cleaner, particularly relates to a kind of fuel filter.
Background technique
Fuel filter is deleterious particle in the engine fuel gas system of filtering automobile and the vitals of moisture, and it has protected oil pump nozzle, cylinder sleeve, piston ring etc., reduces wear, and avoids stopping up.In prior art, fuel filter comprises filter cleaner body and filter core, the inwall of described filter cleaner body and the outer wall of filter core form exocoel, in filter core, it is inner chamber, fuel oil enters inner chamber by exocoel from filter core, and filter core will fire well cuts elimination, but for not processing moisture, moisture enters into engine fuel oil system and can make each parts be corroded by moisture, and each parts easily damage.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of fuel filter, can, effectively by the moisture filtering in fuel oil, prevent that each parts are by moisture corrosion, and simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of fuel filter is provided, comprise filter cleaner body and filter core, the inwall of the outer wall of described filter core and filter cleaner body forms exocoel, on described filter cleaner body, be provided with water outlet, on described filter cleaner body, be provided with the slot around water outlet, in described cavity, be provided with a buoyancy aid, described buoyancy aid density is between fuel density and moisture density, described buoyancy aid is connected with control lid by connecting rod, lid pin and the slot of described control lid are slidably connected, on the lid pin of described control lid, be provided with some through holes.The utility model, sets out the mouth of a river in filter cleaner body bottom, arranges to control to cover water outlet is covered.Because the buoyancy aid arranging can move along with the marginal movement of fuel oil and moisture, the moisture accumulation of exocoel too much, buoyancy aid rises, controlling lid also rises, through hole on lid pin that water outlet covers by control is communicated with exocoel, thereby has realized after water level reach a certain height, by moisture filtering from fuel oil, prevent that each parts are by moisture corrosion, and simple in structure.When after moisture filtering, moisture disappears to the buoyancy of buoyancy aid, and controlling lid can decline under the effect of gravity, thereby water outlet and exocoel are separated.
Further, described lid foot bottom is provided with the first permanent magnet, and the bottom of slot is provided with the second permanent magnet.While adopting the first permanent magnet and the moisture of the second permanent magnet in exocoel few, make to control and cover fast-descending, avoid the excessive of fuel oil.
Further, the bottom of described lid pin is provided with seal ring.Seal ring is set, strengthens the sealing effect of controlling between lid and slot, prevent that fuel oil is excessive.
The beneficial effects of the utility model: set out the mouth of a river in filter cleaner body bottom, control lid is set water outlet is covered.Because the buoyancy aid arranging can move along with the marginal movement of fuel oil and moisture, the moisture accumulation of exocoel too much, buoyancy aid rises, controlling lid also rises, through hole on lid pin that water outlet covers by control is communicated with exocoel, thereby has realized after water level reach a certain height, by moisture filtering from fuel oil, prevent that each parts are by moisture corrosion, and simple in structure.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the sectional view of the utility model fuel filter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment: as shown in Figure 1, a kind of fuel filter comprises: filter cleaner body 1 and filter core 2.On filter cleaner body 1, be provided with filler opening 10 and oil outlet 11.Filter core 2 is arranged in filter cleaner body 1, is provided with the cavity matching with the shape of filter core 2 in filter cleaner body 1, and filter core is arranged in cavity.The outer wall of the outer wall of filter cleaner body 1 and filter core 2 forms exocoel 12, the interior formation inner chamber 13 of filter core 2.Pressure regulator valve 3 is arranged at the edge of filter cleaner body 1, and this pressure regulator valve 3 is communicated with oil outlet 11 by tee union.And the bottom of filter cleaner body 1 is provided with the water outlet 14 being communicated with exocoel 12.On described filter cleaner body 1, be arranged at slot 15, this slot 15 arranges around water outlet 14.The bottom of described exocoel 12 is provided with a buoyancy aid 40, described buoyancy aid 40 covers 42 by a connecting rod 41 with control and is connected, lid pin 420 and the slot 15 of described control lid 42 are slidably connected, on lid pin 420, be provided with some through holes 421, the seal ring 44 that is provided with the first permanent magnet 43 and is close to slot 15 in the bottom of lid pin 420.The bottom of described slot 15 is provided with the second permanent magnet 45.Described buoyancy aid 40 density are based between fuel density and moisture density.
Working principle of the present utility model: fuel oil enters in exocoel 12 by the filler opening 10 on filter cleaner body 1, because fuel density is less than moisture density, moisture is in the bottom of exocoel 12 deposition, top fuel oil enters inner chamber 13 by filter core 2, filter core 2 carries out filtration treatment to fuel oil, by impurity filtering, then fuel oil flows out from oil outlet 11.Long-term accumulates over a long period, the moisture of exocoel 12 bottoms is cumulative, on the separatrix of moisture and fuel oil, rise, because buoyancy aid 40 density are based between fuel density and moisture density, buoyancy aid 40 rises along with marginal rising, drive control to cover 42 and move up, the through hole 421 that exocoel 12 covers on 42 by control is communicated with water outlet 14, thereby moisture flows out from water outlet 14.Along with the outflow of moisture, the separatrix between moisture and fuel oil is declined, thereby the pressure that buoyancy aid 40 is subject to reduce, the active force between the first permanent magnet 43 and the second permanent magnet 45 makes to control and covers 42 declines, and water outlet 14 and exocoel 12 are separated.
These are only mode of execution of the present utility model; not thereby limit the scope of the claims of the present invention; every equivalent structure that utilizes the utility model specification and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner within scope of patent protection of the present utility model.
