Description

Fuel filter

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.

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 fuel filter body, also comprise: the buoyancy aid that is arranged at the valve on water outlet, the mechanical device being connected with valve and is connected with mechanical device, described buoyancy aid density is between fuel density and moisture density.The utility model adopts buoyancy aid to move along with the marginal movement of fuel oil and moisture, in the time that buoyancy aid rises to certain altitude, buoyancy aid acts on the valve on water outlet by mechanical device, water outlet is opened, moisture flows out from water outlet, prevents that the separatrix of moisture and fuel oil is higher than filter core position; In the time that buoyancy aid drops to certain altitude, mechanical device makes valve closing, prevents that fuel oil from leaking outside.

Further, described mechanical device comprises: the slide bar, the contiguous block being connected with slide bar that are connected with the spool of valve, be arranged at the spring between contiguous block and the body of valve, the rotation seat arranging near contiguous block and the dwang being connected with rotation seat, described dwang is bending structure, and described dwang is connected with buoyancy aid.This mechanical device adopts the dwang of bending to be connected with buoyancy aid, and along with the dwang that moves up of buoyancy aid rotates, dwang acts on contiguous block, Compress Spring, and slide bar promotes the spool of valve, and moisture is flowed out from water outlet; Along with the outflow of moisture, buoyancy aid declines, and in the time of buoyancy aid decline certain altitude, when dwang is less than the restoring force of spring to the active force of contiguous block, slide bar pulls the spool of valve, valve closing.

Further, described dwang is 90 ° of bendings, and the bending place of dwang is connected with rotation seat.

The beneficial effects of the utility model: adopt buoyancy aid to move along with the marginal movement of fuel oil and moisture, in the time that buoyancy aid rises to certain altitude, buoyancy aid acts on the valve on water outlet by mechanical device, water outlet is opened, moisture flows out from water outlet, prevents that the separatrix of moisture and fuel oil is higher than filter core position; In the time that buoyancy aid drops to certain altitude, mechanical device makes valve closing, prevents that fuel oil from leaking outside.Thereby realize effective filtering of the moisture in fuel oil, prevented that each parts are by moisture corrosion, also prevented that fuel oil from leaking outside by water outlet.

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, filter core 2 and moisture filtering device 4.

Particularly, 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.

Described moisture filtering device 4 comprises: be arranged at the valve 40 on water outlet 14, the buoyancy aid 46 that acts on the mechanical device on valve 40 and be connected with mechanical device.This mechanical device comprises: the slide bar 41, the contiguous block 43 being connected with slide bar 41 that are connected with the spool of valve 40, be arranged at the spring 42 between contiguous block 43 and valve 40, the rotation seat 44 arranging near contiguous block 43 and the dwang 45 with rotation seat 44 hinges.The density of described buoyancy aid 46 is between fuel density and moisture density.One end of spring 42 is connected with the body of valve 40, and the other end of spring 42 is connected with contiguous block 43.Described dwang 45 is bending structure, and described dwang 45 is connected with buoyancy aid 46.In the present embodiment, described dwang 45 is 90 ° of bendings, and the bending place of dwang 45 is connected with rotation seat 44.

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 46 density are based between fuel density and moisture density, buoyancy aid 46 rises along with marginal rising, the upwards tilting of connecting end of dwang 45 and buoyancy aid 46, the free end 450 of dwang 45 acts on contiguous block 43, contiguous block 43 Compress Springs 42, and slide bar 41 is through the spool of spring 42 conflict valves 40, valve 40 is opened, and moisture flows out from water outlet 14.After moisture flows out, buoyancy aid 46 declines along with the separatrix of moisture and fuel oil, the reaction force attenuation of the free end 450 of dwang 45 to contiguous block 43, when spring 42 resets to contiguous block 43 application of forces, in the time that the large active force than dwang 45 of reposition force of spring 42 is large, contiguous block 43 promotes valve 40 and gets back to original position, and valve 40 is closed, and prevents that fuel oil from flowing out from water outlet 14.

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.
