Abstract
The utility model discloses a kind of self-purging diesel fuel filter structures of band, including bavin filter block, mistake gas bolt and snorkel.Diesel fuel filter is arranged in bavin filter block lower part；Gas bolt is crossed to be arranged on bavin filter block；Snorkel was connected between gas bolt and oil return circuit；Wherein for diesel oil after the filter element filtering of diesel fuel filter, the air adulterated in diesel oil drains into oil return circuit by gas bolt and snorkel.The utility model with self-purging diesel fuel filter structure, the air being entrained in fuel oil can be passed through into gas bolt automatically and snorkel is expelled in the oil return circuit of engine, reduce manual operation and save fuel oil.
Description
Technical field
The utility model is about engine art, especially with regard to a kind of self-purging diesel fuel filter structure of band.
Background technique
As pith-fuel system of engine, low pressure oil way seems indispensable.Sky is doped in oil circuit
Engine is influenced after gas to use, and repeatedly to be restarted if you need to empty air.
The cleaner structure of the prior art usually has the following deficiencies:
Being doped with after air in engine oil path, which influences engine, normally starts, if you need to empty air repeatedly to start by
Diesel fuel filter connector, which opens gap, allows fuel oil to flow directly out, and not only wastes fuel oil in this way, but also pollute environment, also wastes work
When.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
Utility model content
The purpose of this utility model is to provide a kind of self-purging diesel fuel filter structures of band, can be vented automatically,
Avoid the multiple starting of engine.
To achieve the above object, the utility model provides a kind of self-purging diesel fuel filter structure of band, including bavin filter
Seat crosses gas bolt and snorkel.Diesel fuel filter is arranged in bavin filter block lower part；Gas bolt is crossed to be arranged on bavin filter block；Ventilation
Pipe was connected between gas bolt and oil return circuit；Wherein diesel oil adulterates in diesel oil after the filter element filtering of diesel fuel filter
Air drain into oil return circuit by gas bolt and snorkel.
In a preferred embodiment, bavin filter block includes oil inlet and oil outlet, and diesel oil enters diesel oil through oil inlet
It is discharged after the filter element filtering of filter from oil outlet.
In a preferred embodiment, gas bolt is crossed to be arranged between oil outlet and the filter core of diesel fuel filter.
It in a preferred embodiment, further include screw hole with self-purging diesel fuel filter structure, screw hole setting is going out
Between hydraulic fluid port and the filter core of diesel fuel filter.
In a preferred embodiment, gas bolt seal is crossed to be arranged in screw hole.
Compared with prior art, the utility model has the advantages that with self-purging diesel fuel filter structure
Directly air can be drained into automatically at gas bolt, air and fuel oil reduce manual operation, reduce combustion with tube runs to fuel tank
Oil waste.
Detailed description of the invention
Fig. 1 is the stereochemical structure signal with self-purging diesel fuel filter structure according to one embodiment of the utility model
Figure.
Main appended drawing reference explanation:
1- bavin filter block, 11- oil inlet, 12- oil outlet, 2- cross gas bolt, 3- snorkel, 4- diesel fuel filter.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, Fig. 1 is according to the vertical with self-purging diesel fuel filter structure of one embodiment of the utility model
Body structural schematic diagram.According to a kind of self-purging diesel fuel filter structure of band of the preferred embodiments of the present invention, including bavin
Filter block 1 crosses gas bolt and snorkel.
In some embodiments, diesel fuel filter 4 is arranged in the lower part of bavin filter block 1, bavin filter block 1 include oil inlet 11 with
And oil outlet 12, diesel oil are expelled to engine from oil outlet 12 after oil inlet 11 enters the filter element filtering of diesel fuel filter 4
In oil supply loop.A screw hole is processed between the oil outlet 12 of bavin filter block 1 and the filter core of diesel fuel filter 4, on the screw hole
Sealed set crosses gas bolt 2；Crossing, snorkel 3 is set between gas bolt 2 and oil return circuit；In this way, diesel oil is through diesel fuel filter 4
Filter element filtering after, the air adulterated in diesel oil during startup oil pressure can automatically by air squeeze to highest point cross gas
At bolt 2, subsequent diesel oil and air will pass through snorkel 3 and flow to oil return line.
In conclusion the utility model has the advantage that engine fuel with self-purging diesel fuel filter structure
When adulterating air in pipeline, when starting under the action of oil pressure, directly air was drained into automatically at gas bolt, air and fuel oil
With tube runs to fuel tank, manual operation can be not only reduced in this way, also reduces the waste of fuel oil, and solves diesel oil and flow to
Engine surface and the problem of pollute environment.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can be realized and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
