Description

The rotation fitting type fuel filter
Technical field
The utility model relates to the filter cleaner field, is specially a kind of rotation fitting type fuel filter.
Background technique
Fuel filter is connected on the pipeline between fuel pump and the throttle valve body filler opening, and effect is deleterious particle and the moisture content in the filtering engine fuel gas system, with protection oil pump nozzle, cylinder sleeve, piston ring etc., reduces wear, and avoids stopping up.Fuel filter comprises shell, the filter core that has filter paper to constitute in the shell, and the fuel filter of existing technology is all-in-one-piece, and filter paper is fixed in the shell, and the filtering effect can't guarantee, and regular maintenance and replacing inconvenience.
The model utility content
The utility model purpose provides a kind of rotation fitting type fuel filter, can't guarantee to solve existing technology fuel filter filtering effect, changes the problem of inconvenience.
In order to achieve the above object, the technological scheme that the utility model adopted is:
The rotation fitting type fuel filter comprises it is characterized in that the shell of open-topped, bottom lock: be provided with the supported spring that the lower end is connected outer casing bottom in the said shell; And the filter core assembly that supports by supported spring, said filter core assembly comprises upper and lower end cap with central through bore and the center tube that connects upper and lower end cap, said lower end cap places the supported spring upper end; The downwarping of upper end cap edge; Said center tube is with many circle filter paper outward, and filter paper is spacing by upper end cap edge curved section, has the sealing gasket of band interior threaded hole to be installed in the central through bore of upper end cap; Said cover top portion faucal place is covered with spiral shell plate assembly; Said spiral shell plate assembly is made up of spiral shell plate, fixed plate, and said spiral shell plate lower face has is with externally threaded central boss, and said fixed plate upper plate surface forms circular groove; Be provided with seal ring in the circular groove; The corresponding circular groove of fixed plate lower face position is provided with annular bead, and the annular bead of said fixed plate lower face is welded on the upper plate surface of spiral shell plate, and the central boss of said spiral shell plate is screwed in the interior threaded hole of said sealing gasket.
The utility model is simple in structure, is easy to realize.Filter paper is enclosed within on the center tube of filter core assembly, and filter core assembly is supported by spring, when filter core assembly rotates; Can guarantee that through the torsion of spring filter core assembly resets; Guaranteed the filtering effect of filter cleaner, simultaneously spiral shell plate assembly covers in cover top portion, and sealing gasket is threaded in the central boss through the spiral shell plate and the shell; Can directly take off the inner filter paper of spiral shell plate unit replacement when changing like this, conveniently save trouble.The utility model can guarantee the filtering effect of filter cleaner effectively, also greatly facilitates the repair and replacement of filter cleaner.
