Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but does not constitute of the present utility model
Any restriction.
As it is shown in figure 1, a kind of fuel filter with high-efficiency exhaust function, mainly include filter tank 1, filter block, described filter
Tank 1 mainly includes shell 8, thread plate sub-unit 2, inner seal ring 3, filter element sub-unit 15, holds out against spring 10, discharge valve seat
11, discharging valve sub-unit 12；Described shell 8 is provided with upper and lower two openings, and wherein upper shed is connected with thread plate sub-unit 2,
Under shed is connected with discharge valve seat 11, and described discharge valve seat 11 is connected with discharging valve sub-unit 12, described filter element sub-unit 15
Being located at the inside of shell 8, described filter element sub-unit 15 mainly includes filter element upper end cover 5, filter element bottom end cover 9, is positioned at core upper end cover 5
And filter paper 7 between filter element bottom end cover 9 and to be positioned at filter element sub-unit 15 internal for supporting the central canal 6 of filter paper 7, described
Inner seal ring 3 it is provided with between thread plate sub-unit 2 and filter element upper end cover 5.
As optimal technical scheme, nitrile rubber can be selected in the top and the bottom of described inner seal ring 3, acts primarily as sealing and makees
With, and mid portion is venting plug material.As optimal technical scheme, described venting plug material can elect sintered copper as.
As in figure 2 it is shown, described inner seal ring 3 has axially extending bore 13, described axially extending bore 13 along its longitudinal axis direction
Fuel oil after filter passes through.At least offer one on the sidewall of described inner seal ring 3 and run through inner seal ring inner cylindrical wall face
With the lateral through hole 4 of inner seal ring outside cylinder wall, the shape of cross section of described lateral through hole 4 is preferably circular, it is also possible to
For other shape, such as square, rhombus, trapezoidal etc..Described venting plug 16 is arranged on lateral through hole 4 by interference fit
In.The diameter A of described inner seal ring 3 is preferably 1-20mm according to cleaner flow set, described diameter A.Described sintering copper bar
Vent plug shape is elected as identical with described lateral through hole 4 shape, but size is bigger than lateral clear size of opening, to reach interference fit.Institute
Pressure is passed through respectively at the lower surface of thread plate sub-unit 2 and the upper surface of filter element upper end cover 5 in G face and the F face of stating inner seal ring 3
Contracting is tightly connected.
Described inner seal ring 3 includes a lateral through hole of circle 4, but understand completely can for the engineers and technicians of this area
With according to the actual needs and the situation such as the strength of materials of inner seal ring 3, structure arranges the through hole of varying number, different-diameter
Through hole.Additionally, the axis of lateral through hole 4 can also be non-intersect with the longitudinal axis of inner seal ring 3, the axis of lateral through hole 4
Can not also level, tilt the most downward or upward, or the combination of above-mentioned two situations.
As it is shown on figure 3, the described lateral through hole of inner seal ring 3 is provided above a protrusion block 14, it is to avoid cleaner is worked
The fuel oil flow down from thread plate fuel feed hole in journey washes away venting plug, and affects degassing function.The knot of described protrusion block 14
Structure preferred size C, D, E can according to actual needs and the size of described inner seal ring 3, the strength of materials and fuel filter
Metered flow determines.
In engine working process, accumulate in the gas in fuel filter and pass through venting plug 16, through lateral through hole
4, axially through hole 13, finally discharge fuel filter.By reasonable selection venting plug parameter, degassing function can be reached.
It addition, venting plug does not results in decisive influence to filter efficiency and the oil-water separation efficiency of fuel filter.This filtering utensil
There is the degassing function of efficient stable, can effectively solve air accumulation in filter tank and the engine start difficulty that causes even starts mistake
The problem lost.
Of the present utility model ultimate principle and principal character have more than been shown and described.The technical staff of the industry should
Solving, this utility model is not restricted to the described embodiments, and simply illustrates that this practicality is newly described in above-described embodiment and description
The principle of type, on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications,
In the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope by appended
