Description
[technical field]
The present invention relates to the automobile filter apparatus field, be specifically related to a kind of screw type gasoline filter.
[background technique]
The effect of screw type gasoline filter is with moisture in the gasoline and impurity filtering, and gasoline gets into through oil inlet pipe in the sediment bowl of filter cleaner under the effect of petrol pump during engine operation; Because this moment, volume became big; Flow velocity diminishes, and than the bottom that the heavy water of oil and impurity particle just are deposited in cup, light impurity flows to filter core with gasoline; And the gasoline of cleaning flows out through oil pipe from the inside that the micropore of filter core oozes people's filter core then.
At present; The filter paper that the screw type gasoline filter is adopted mostly is only to possess the filter paper that filters solid impurity; Though this gasoline filter paper filters solid impurity, and is powerless to the separation of moisture in the gasoline, and not only contain solid impurity in the gasoline usually; Also contain other impurity such as moisture, it is often not good to rely on the mode of conventional natural sedimentation to filter the effect of moisture.Therefore although present widely used BBG is strict more to petrol-injected control, the quality requirements of gasoline is improved day by day, the moisture that contains in the gasoline then is difficult to through existing screw type gasoline filter filtering.In a single day moisture in the gasoline get into motor, promptly possibly cause following infringement to motor:
1, makes the precision pair of motor power supply system be in the semi-dry friction state, cause the strong wear of precision pair.
2, cause that fuel feeding is the corrosion of smart even part and cylinder.
3, dissolve some mechanical admixture, for example salt is difficult for being removed by filter after salt is dissolved, causes the corrosion of oil supply system precision pair and cylinder.
[summary of the invention]
To the deficiency that existing technology exists, the object of the present invention is to provide a kind ofly through helical flow path is set, make the filter cleaner can cyclone filter, thereby strengthen the novel screw type gasoline filter of filtering effect.
For realizing above-mentioned purpose, the invention provides following technological scheme: a kind of screw type gasoline filter comprises housing, capping, filter core; Said housing bottom is provided with drain valve; Said filter core is with being provided with supported spring between the housing bottom, and said capping is provided with oil inlet pipe and oil outlet tube, said filter core by upper end cap, lower end cap and be located at upper end cap and lower end cap between the longitudinal folding hollow cylindrical filter paper that constitutes form; Two annular end faces of this filter paper are caught up with end cap and the fixing bonding of lower end cap respectively; It is characterized in that: said upper end cap also is provided with oil road, and this oil road is communicated with oil outlet tube, and said filter paper center also is provided with filter shaft; Filter shaft is provided with helical flow path all over the body, and helical flow path is communicated with oil road.
Through adopting technique scheme; Gasoline once filters through filter paper and flows into the filter paper inboard; Helical flow path on filter shaft flows to the oil road rotation of upper end cap then; The centrifugal force of the gasoline generation that the area of contact of the gasoline after the effective increase of rotating flow kinetic energy is once filtered and the folded part of filter paper, rotation simultaneously flow also can further get rid of moisture residual in the gasoline and impurity to filter paper, thereby remaining impurity is carried out secondary filter; The moisture that throws away also can precipitate once more, thereby the gasoline that flows into oil road is more cleaned.
The present invention further is set to: said filter shaft hollow; Two end faces of filter shaft are tightly connected with upper end cap and lower end cap respectively; Also be provided with oil input channel on the said upper end cap, this oil input channel one end is communicated with the axis hole of oil inlet pipe and filter shaft, and an end is communicated with the deposition chamber of housing.
Through adopting technique scheme; The gasoline that flows in the oil inlet pipe can flow into the axis hole of filter shaft earlier; The moisture that contains in the gasoline can here once precipitate in advance; Increased the filtering effect of filter cleaner, filter in the deposition chamber that flows into filter cleaner afterwards again, and it is to prevent that the gasoline in the axis hole from directly infiltrating the filter paper inner chamber that two end faces of filter shaft are tightly connected with upper and lower end cap respectively.
The present invention further is set to: also be provided with at least 1 choked flow mouth on the said helical flow path.
In above-mentioned the setting, it is for the runner that makes helical flow path narrows down that the choked flow mouth is set, thereby the gasoline flow velocity on the helical flow path is accelerated, and strengthen the filtering effect of eddy flow, and the choked flow wall of choked flow mouth also can play the effect that stops to moisture.
The present invention further is set to: said helical flow path closely cooperates with filter paper inwall formation.
Above-mentioned setting is to flow in order to make gasoline can better prolong helical flow path, stop gasoline between helical flow path and the filter paper inwall the gap directly rise, strengthen the filtering effect of eddy flow.
The present invention further is set to: the oil road below of said upper end cap is provided with the noise elimination piece.
This is provided with the noise that can effectively reduce filter cleaner.
The present invention further is set to: also be provided with outlet valve on the said capping sub-assembly.
During this is provided with, can let the filter cleaner pressure release, guarantee the filter cleaner long-term stable operation through outlet valve.
The present invention further is set to: said lower end cap is provided with buckle, and said supported spring is fixedly connected with lower end cap through this buckle.
This is provided with and can guarantees the stable of supported spring and filter core, prevents filter cleaner in vibrations, supported spring displacement filter core occurs and tilts and the supported spring obscission.
The present invention is ingenious must to be provided with helical flow path at the filter core outer wall, thereby makes filter cleaner ability cyclone filter, has strengthened filtering effect greatly, simple in structure, with low cost, and in filter cleaner, has set up noise elimination piece and gas bleeder valve, has improved the whole usability of filter cleaner.
