Abstract
The utility model discloses an anti-blockage filter for a pipeline of a fuel injection system. A conical spherical filter screen (1) is fixedly connected with a cylinder opening of a filter core hoop (5) through top conical distributed spokes (4), the cylinder height of the filter core hoop (5) is greater than that of an outer seat body circular-ring (7), and the filter core hoop (5) is assembled in a cylinder hole of the outer seat body circular-ring (7) in an interference fit manner to form a stepped conical surface filter. The conical spherical filter screen is arranged on a cloth screen framework, so that the inhibition of fuel flowing in the pipeline is reduced; residual impurities of a filter liquid medium are diffused to an impurity storage area, formed in the pipeline, of the stepped conical surface filter by virtue of the pressure of the fuel in the pipeline and are not prone to staying on the conical spherical filter screen, so that the probability of blocking and sealing of the filter screen and the frequency of cleaning are reduced, the filter screen is easy to clean, the service life of the filter screen is further prolonged, and the deformation or even damage caused by the frequent cleaning is avoided.
Description
Technical field
The utility model relates to a kind of filter that is mainly used in fuel injection system pipeline.
Background technology
The piping filter of most is all filter screens of flat form.It is large that straight formula filter hinders power to fuel oil mobile in pipeline, filtration time is understood precipitated impurities after growing on screen pack or sieves, impurity in fuel oil easily accumulates on the whole wire side of filter screen, filter cloth is stopped up, cause oil circuit to flow not smooth, stop up even completely, reduce filter efficiency and even filtering holes is blocked, cause fuel injection system fault.Straight filter screen produces spherical deformation under the effect of pipeline fuel pressure, filter liquide media filtration impurity is accumulated on to distortion filter screen sphere, stop up oil circuit through long time integration, because filter screen intensity is low, it is damaged that repeatedly frequent clean adds large deformation gradually, can make filter cloth minimizing in service life.
Summary of the invention
The purpose of this utility model is the weak point existing for above-mentioned prior art, provides a kind of impurity to be difficult for accumulating on wire side, can reduce filter gauze cleaning number of times and life-extending longer fuel injection system pipeline block-resistant filter.
The utility model solves the technical scheme that its technical problem adopts, a kind of fuel injection system pipeline block-resistant filter, comprise taper spheric filter screen 1, cloth network framework 2, net ring support body 3 and pedestal outer toroid 7, it is characterized in that: taper spheric filter screen 1 connects firmly on the cylinder port of filter core net circle 5 by top tapered distribution spoke 4, filter core net circle 5 cylindrical shell height are greater than pedestal outer toroid 7 cylindrical shell height, interference is assemblied in 7 holes of pedestal outer toroid, forms a ladder step conical surface filter.
The utlity model has following beneficial effect.
The utility model adopts taper spheric filter screen to be arranged on cloth network framework, reduce the inhibition to flow fuel oil in pipeline, by ducted fuel pressure, filter liquide medium residual impurity is diffused to the impurity memory block that ladder step conical surface filter forms in pipeline, impurity in fuel falls into space, impurity memory block in the effect of fluid power, be difficult for resting on taper ball filter screen, so just reduce the obstruction to filter screen, the probability blocking and the number of times of frequent clean, and be easy to clean, and then extend service life of filter screen, avoid frequent clean to be vitiablely out of shape.

Detailed description of the invention
Consult Fig. 1-Fig. 4.Fuel injection system pipeline block-resistant filter, comprises taper spheric filter screen 1, cloth network framework 2, net ring support body 3 and pedestal outer toroid 7.Taper spheric filter screen 1 connects firmly on the port of net circle cylinder 5 by top tapered distribution spoke 4, and filter core net circle 5 cylindrical shell height are greater than pedestal outer toroid 7 cylindrical shell height, and interference is assemblied in 7 holes of pedestal outer toroid, forms a ladder step conical surface filter.
Annular protrusion 6 in pedestal outer toroid 7 cylindrical shell inboard aperture can be realized interference assembling by annular groove on filter core net circle 5 cylindrical shell cylindricals.Filter core net circle 5 is working of plastics.Filter core net circle 5 by injection mo(u)lding and with cylindrical shell cylindrical on annular groove link together.Taper spheric filter screen 1 connects firmly below cloth network framework.The filter tensioner that forms the ladder step conical surface is installed in oil line pipe 8, formation be impurity memory block 9 around space.When passing into after fluid in pipeline 8, impurity in fluid is stopped by taper spheric filter screen 1, under the effect of fluid power, taper spheric filter screen top flow ipe 8 is crossed on edge, filter liquide medium residual impurity is diffused to the impurity memory block 9 that pipeline 8 surrounds along the ladder step conical surface, under depositing under the effect of eddy current, and can not stay in filter conical top always, cause filter net jam.
