Abstract
The utility model relates to an automobile fuel filter device, in particular to a fuel filter which comprises a dish cover, a shell and a filter core installed in the shell, and is characterized by also comprising a filter core mounting shaft that penetrates through the filter core upwards from a mounting hole at the bottom part of the shell, wherein the lower end of the filter core mounting shaft is a shaft cap which is welded at the position of the mounting hole at the bottom part of the shell; the upper end of the filter core mounting shaft is provided with a screw hole; the dish cover is in threaded connection with the screw hole of the filter core mounting shaft by bolts, so that the dish cover and the shell are pressed tightly; the dish cover is provided with a sealing groove that is configured with the upper edge of the shell; and a pressure-resisting sealing ring is placed in the sealing groove. In the utility model, the filter core mounting shaft is installed upwards from the mounting hole at the bottom part of the shell, thus leading the connection between the dish cover and the shell to be more reliable and the inner structure of the fuel filter to be more compact; and the pressure-resisting sealing ring can prevent fuel from effusing from the sealing position of the dish cover and the shell when the fuel filter is under overlarge pressure.
Description
Technical field
The utility model relates to the vehicle fuel filtrating equipment, particularly a kind of fuel filter.
Technical background
The fuel filter string is on the pipeline between fuel pump and the throttle valve body filler opening.The effect of fuel filter is that solid sundries such as being contained in iron oxide in the fuel oil, dust is removed, and prevents that oil-fired system from stopping up (particularly oil nozzle), reduces mechanical wear, guarantees motor stable operation, improves reliability.By the structure of oil burner form by stainless support by in an aluminum hull and one, efficient filter paper assembly is housed on support, filter paper becomes cosmos, to increase circulation area.
282 type gasoline filter structures are made up of loam cake, filter core and sediment bowl, and loam cake is equipped with into and out of oil pipe, and filter core covers in last with bolt.The sealing gasket sealing is housed between filter core and the loam cake, and tightly covers last with screw or screw-in mode.The purge cock of discharging impurity is equipped with in the sediment bowl bottom.Under the petrol pump suction, fuel oil enters the sediment bowl from inlet connector, and moisture and bigger impurity are blocked on the filter core outer surface, and the vapour of cleaning stain enters filter core inside, flows to petrol pump through oil outlet tube.But the shortcoming of above filter cleaner is that fixedly the bolt of filter core is loosening easily, causes filter core shift in position in sediment bowl, thereby influences the strainability of filter cleaner owing to relatively jolt in the car running process.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and prevent because the car running process moderately gusty air causes the loosening fuel filter that walks of housing inner filter core.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of fuel filter, comprise disk cover, housing, filter core is installed in the housing, it is characterized in that: also comprise the filter core installation shaft that is upward through filter core from the mounting hole of housing bottom, the lower end of described filter core installation shaft is the axle cap that is welded on the mounting hole position of housing bottom, the upper end of described filter core installation shaft has screw, thereby described disk cover compresses disk cover and housing by the screw scyewed joint of bolt and filter core installation shaft, described disk cover is provided with the seal groove with housing upper edge phase configuration, is placed with the pressure-resistant seal circle in the seal groove.
By above scheme, on the filter core installation shaft of described filter core bottom a tower spring is installed, thereby described tower both ends of the spring be resisted against respectively filter core bottom and housing bottom with the filter core elastic compression in housing.
By above scheme, filter core adopts helical glass fiber bundle, acrylic resin beading to fix filter paper.
The contrast prior art, useful advantage of the present utility model is:
1, the filter core installation shaft of passing filter core is upwards installed from the mounting hole of housing bottom, and rational in infrastructure, simple installation is reliable.The upper end of filter core installation shaft has screw, thereby the screw spiral marking connection of described disk cover by bolt and filter core installation shaft compresses disk cover and housing.Compared with prior art, the filter core installation shaft is upwards installed from the mounting hole of housing bottom, and it is more reliable to make that disk cover connects with housing, fuel filter internal structure compactness.Because the EFI filter cleaner often bears the fuel pressure of 200～300kPa, therefore, this filter cleaner compressive strength fitness for purpose reaches more than the 500kPa, the filter cleaner of Carburetor then there is no need to reach so high pressure, therefore the disk cover of the utility model fuel filter is provided with the seal groove with housing upper edge phase configuration, be placed with the pressure-resistant seal circle in the seal groove, the pressure-resistant seal circle can prevent that fuel filter fuel oil when pressure is excessive from oozing out from the sealing part of disk cover and housing.
2, on the filter core installation shaft of filter core bottom a tower spring is installed, thus described tower both ends of the spring be resisted against respectively filter core bottom and housing bottom with the filter core elastic compression in housing.The elastic force of tower spring makes filter core position in housing be difficult for change, thereby can prevent more completely because the situation that the car running process moderately gusty air causes the housing inner filter core to walk.
3, filter core adopts helical glass fiber bundle, acrylic resin beading to fix filter paper, prevents filter paper fold, distortion, to guarantee filtering effect.
The utility model is simple in structure, cost is low.

Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
The utility model embodiment as shown in Figure 1, a kind of fuel filter, comprise disk cover 1, housing 2, filter core 3 is installed in the housing 2, it is characterized in that: also comprise the filter core installation shaft 4 that is upward through filter core from the mounting hole of housing bottom, the lower end of described filter core installation shaft 4 is the axle cap 4-1 that is welded on the mounting hole position of housing bottom, the upper end of described filter core installation shaft 4 has screw 4-2, thereby described disk cover 1 compresses disk cover 1 and housing 2 by the screw 4-2 spiral marking connection of bolt 5 with filter core installation shaft 4, disk cover 1 is provided with the seal groove with housing 2 upper edge phase configuration, is placed with pressure-resistant seal circle 7 in the seal groove.
Concrete, on the filter core installation shaft 4 of described filter core 3 bottoms a tower spring 6 is installed, thereby described tower spring 6 two ends be resisted against respectively filter core 3 bottoms and housing 2 bottoms with filter core 3 elastic compressions in housing 2.
Concrete, filter core 3 adopts helical glass fiber bundle, acrylic resin beading to fix filter paper.
Above embodiment is preferred embodiment of the present utility model, is not the utility model is done more restriction, and every foundation is done simple modification or variation that is equal to and modification to technological essence of the present utility model, all still belongs to the scope of the utility model protection.
