Abstract
The utility model relates to a fuel filter, in particular to a fuel filter with a filter screen mechanism. The fuel filter with the filter screen mechanism mainly solves the technical problem that impurities inside the fuel filter easily enter into a fuel injection system. The technical scheme includes that the fuel filter with the filter screen mechanism comprises an outer shell sub assembly, a thread cover plate sub assembly and a filter core sub assembly, and the filter core sub assembly is fixed in the outer shell sub assembly by a filter core sealing ring and a spring. The fuel filter with the filter screen mechanism is characterized in that a filter device is added on an opening end cover. The edge of the opening end cover is step-shaped, an upper portion step clamps filter paper and a central pipe, and a lower portion and an elastic reversing button at the upper end of the filter device form clamping type connection. The filter device is a cylinder-shaped hollow structure, a filter screen is coated outside the filter device, a triangle sealing ring is distributed on the circumference where the filter device is matched with the opening end cover, and the triangle sealing ring and the opening end cover form interference fit. Secondary filter is formed inside the filter in a filter net form, and high cleanness requirement of a product is achieved under the condition that product cost is not increased.
Description
Technical field
The utility model relates to a kind of fuel filter, be particularly related to a kind of high cleanliness fuel filter with filter screen mechanism, by forming secondary filter in the inner form that increases filter screen of filter cleaner, in the situation that do not increase cost of production, realize the more high cleanliness requirement of product.
Background technique
Traditional filter cleaner is because the narrow limitation of structure and production, the narrow limitation that reaches manufacturing process in the process of producing unavoidably can be brought metal fragment and dust impurity, therefore inevitably these impurity directly enter pipeline road and then enter common rail fuel injection system, cause the premature wear of injection system, the external method that improves at present the filter cleaner turbidity test mainly is to adopt dust-free workshop to produce filter cleaner, this will certainly increase the production cost, and existing domestic filter cleaner turbidity test all are difficult to the fuel filter turbidity test requirement that reaches more and more higher.With reference to Fig. 1, existing fuel filter comprises shell sub-assembly 6 and thread plate sub-assembly 7 and filter core sub-assembly 5, described filter core sub-assembly 5 is fixed in the shell sub-assembly 6 by filter core seal ring 8 and spring 9, described filter core sub-assembly 5 is mainly by open end cap 1, the end cap 2 of remaining silent, filter paper 3 and center tube 4 form by the filter paper adhesive curing, and this filter cleaner can filter external impurity, if still filter cleaner inside can't be processed with impurity.
Summary of the invention
The purpose of this utility model provides a kind of high cleanliness fuel filter with filter screen mechanism, mainly solves fuel filter inside and carries the technical problem that impurity easily enters fuel injection system.This filter cleaner can effectively filter out the metal fragment that brings in the production process, avoids these impurity to enter injection system, is protected to guarantee fuel injection system.
The technical solution adopted in the utility model is: with the fuel filter of filter screen mechanism, comprise shell sub-assembly and thread plate sub-assembly and filter core sub-assembly, described filter core sub-assembly is fixed in the shell sub-assembly by filter core seal ring and spring, it is characterized in that: set up filtrating equipment in open end cap.
Described open end cap edge is step-like, and upper step is blocked filter paper and center tube, and lower step forms snap-in the connection with the elasticity back-off of filtrating equipment upper end.
Described filtrating equipment is the tubular hollow structure, and the outside coats filter screen, is arranged in filter cleaner axis and oil circuit outlet position.
At the circle distribution triangular sealing ring that filtrating equipment cooperates with open end cap, triangular sealing ring and open end cap form interference fit, form sealing.
The beneficial effects of the utility model are: the oil outlet at filter cleaner increases together filtration, guarantees that the large granular impurity that produces in process of production is filtered, and can not enter injection system, is effectively protected to guarantee fuel injection system.Filtrating equipment tubular hollow design is covered filter screen outward, not only rises to reach strainability and have stronger structural strength; The axis design of filtrating equipment can effectively reduce and increase the flow resistance that filter screen brings; Novel open end cap and filter screen design, reliability between the two is sealed and matched and the locking mechanism of reliability, effectively filter out the metal impurities that bring in the production process, so that filter cleaner is in the situation that profile size constancy and cost increase seldom, have effectively promoted the turbidity test of product.
Description of drawings
Fig. 1 is the structural representation of original fuel filter.
Fig. 2 is the utility model structural representation.
Among the figure: 1-open end cap, the 2-end cap of remaining silent, 3-filter paper, 4-center tube, 5-filter core sub-assembly, 6-shell sub-assembly, 7-thread plate sub-assembly, 8-filter core seal ring, 9-spring, 10-filtrating equipment, 11-triangular sealing ring, 12-elasticity back-off.
Embodiment
With reference to Fig. 2, the fuel filter of the utility model band filter screen mechanism, comprise shell sub-assembly 6 and thread plate sub-assembly 7 and filter core sub-assembly 5, described filter core sub-assembly 5 is by filter core seal ring 8 and spring 9, be fixed in the shell sub-assembly 6, described filter core sub-assembly 5 is mainly by open end cap 1, the end cap 2 of remaining silent, filter paper 3 and center tube 4 form by the filter paper adhesive curing, described open end cap 1 edge is step-like, upper step is blocked filter paper 3 and center tube 4, lower step forms snap-in the connection with the elasticity back-off 12 of filtrating equipment 10 upper ends, has avoided coming off of filter screen.At the circle distribution triangular sealing ring 11 that filtrating equipment 10 cooperates with open end cap 1, after this filtrating equipment 10 was pressed into open end cap 1, triangular sealing ring 11 formed interference fit with open end cap 1, plays seal action.
With reference to Fig. 2, be the oil circuit direction shown in the arrow, after fuel oil enters from filler opening, by the filtration of fuel filter filter core sub-assembly 5, by center tube 4, then the secondary filter of the filter screen of process filtrating equipment 10 enters into oil circuit from the screw mouth of thread plate sub-assembly 7.
