Description
Technical field
The utility model belongs to cleaner technical field, and in particular to a kind of filter seat.
Background technology
Fuel filter is an important spare part in combustion engine powered equipment such as vehicle, engineering machinery, ship, it
For the impurity in filter fuel, avoid the impurity in fuel oil from entering internal combustion engine, effectively extend the service life of internal combustion engine,
Fuel filter is that clean fuel oil, fuel cleaning are provided for elements such as the fuel pumps, oily rail, atomizer of engine fuel oil system
The oil feed pump of device institute band is to discharge the air in the new cleaner of fuel system and pipeline, and the fuel oil in fuel tank is passed through low
Force feed road fills cleaner or fuel pipe, exists when the engine is worked in the oil circuit of fuel system without air, ensures to start
Function normally starts and work.
It is well known that fuel oil will certainly be doped with minute bubbles in flowing, the fuel oil containing minute bubbles enters fuel filter
After device, due to the suction function needed for fuel oil filter normal work itself, stopped plus by filter element, in fuel oil
Bubble is separated and is clustered together with fuel oil.If the gas isolated can not discharge in time, in the prior art, used at present
Fuel oil filtering device in the course of the work, engine misses shut down after, petroleum pipeline intermediate fuel oil is passed back into fuel filter, meeting
The backflow of the pipeline and fuel filter internal fuel of fuel filter connection is caused, fuel filter seat cleaner connecting portion
Fuel flow returns, cause engine fuel oil system air in pipeline to be assembled, so as to form air cavity, malleation can be formed in filter chamber
Area, the liquid level of fuel oil will be depressed into the bottom of fuel oil filter by malleation, cause the liquid level of fuel oil to reduce.Engine is in flame-out weight
Qi Shi, due to the presence of gas in fuel pipe and cleaner, combustion system of engine fuel delivery can be caused insufficient, and then lead
Cause engine start is difficult can not even start.
The content of the invention
Technical problem to be solved in the utility model is：A kind of filter seat is provided, opened again after engine misses
When dynamic, it can avoid causing the phenomenon of difficulty in starting due to fuel delivery deficiency.
In order to solve the above technical problems, the technical solution of the utility model is：Filter seat, set on the filter seat
There are oil inlet, cleaner connecting portion and oil-out, the cleaner connecting portion offers oil discharge passage, the oil discharge passage and institute
State oil-out connection；The cleaner connecting portion is provided with oil suction chamber, the oil suction chamber connects with the oil inlet；It is special
Sign is that the oil discharge passage or the oil inlet or the oil-out are provided with check valve.
Further, the check valve is arranged at the oral area of the oil discharge passage.
Further, the check valve includes valve pocket, and the valve pocket is fixed on the oral area or described of the oil discharge passage
Oil inlet or the oil-out, valve seat, valve block and back-moving spring are provided with the valve pocket, in the effect of the back-moving spring
Under the valve block close the oil outlet of the valve seat.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
Oil inlet, cleaner connecting portion and oil-out, cleaner connecting portion are provided with filter seat of the present utility model
Oil discharge passage is offered, oil discharge passage connects with oil-out；Cleaner connecting portion is provided with oil suction chamber, oil suction chamber and oil-feed
Mouth connection；Oil discharge passage or oil inlet or oil-out are provided with check valve, engine at work, the normal work of fuel filter
Make；Engine is after flame-out shut down, due to the effect of check valve, the pipeline and fuel filter for preventing fuel filter to connect
Internal fuel flow returns, so that will not form air cavity due to air be present inside fuel filter and fuel pipe, meeting exists
Zone of positive pressure is formed in filter chamber, the liquid level of fuel oil will be depressed into the bottom of fuel oil filter by malleation, cause the liquid level of fuel oil to drop
It is low, and cause fuel delivery insufficient, during so as to avoid engine from being again started up because fuel delivery deficiency and caused by start it is tired
Difficult phenomenon.
Check valve is arranged at the oral area of oil discharge passage, is easily installed and changes.

Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
Oil inlet 2, cleaner connecting portion 1 and oil-out 3, filtering are provided with reference to shown in Fig. 1 to Fig. 3, on filter seat
Device connecting portion 1 offers oil discharge passage, and oil discharge passage connects with oil-out 1；Cleaner connecting portion 1 is provided with oil suction chamber,
Oil suction chamber connects with oil inlet 2；Oil discharge passage or oil inlet 2 or oil-out 3 are provided with check valve.Check valve can prevent fuel oil
Fuel flow returns inside the pipeline and fuel filter of cleaner connection, so that inside fuel filter and fuel pipe not
Air cavity can be formed due to air be present and cause fuel delivery insufficient, because fuel oil supplies during so as to avoid engine from being again started up
The phenomenon of difficulty in starting is caused to deficiency.
For the ease of installing and changing, check valve is arranged at the oral area of oil discharge passage.
Check valve in the present embodiment includes valve pocket 6, and valve pocket 6 is fixed on the oral area of oil discharge passage and either oil inlet or gone out
Hydraulic fluid port 3, valve seat 5, valve block 8 and back-moving spring 7 are provided with valve pocket 6, in the presence of back-moving spring 7 on the closed valve seat 5 of valve block 8
Oil outlet.
Check valve can take various forms, such as umbrella valve, and the structure such as globe valve, or other conventionally forms are unidirectional
Valve.
Valve seat 5 can be fixed together with valve pocket 6 by way of welding, it is of course also possible to pass through other routines
The mode that is fixedly connected link together.
When will use filter seat of the present utility model below, with the mouth of the oil discharge passage opened up in cleaner connecting portion 1
Exemplified by portion sets check valve, ensure that the process that engine is restarted quickly is described in detail：When the engine operates, fuel cleaning
Device normal work, fuel oil are flowed into by the oil inlet on the oil inlet 2 on filter seat and the connecting plate in filter body 9
In filter body 9；Then for fuel oil after the filtering of filter core 4, the hole through the central tube in filter body 9 flows into center
The inner chamber of pipe.Fuel oil flows out fuel filter body 9 through the oil-out on connecting plate, and under the effect of the pressure, valve block 8 is opened,
Fuel oil flows into oil discharge passage by the oil outlet on valve seat 5, the hole among valve pocket 6, and supply engine uses.Work as engine misses
When, valve block 9 blocks the oil outlet on valve seat 5 in the presence of return spring 7, prevents pipeline and combustion that fuel filter connects
Fuel flow returns inside oil rectifier, so that inside fuel filter and fuel pipe gas will not be formed due to air be present
Chamber, zone of positive pressure can be formed in filter chamber, the liquid level of fuel oil will be depressed into the bottom of fuel oil filter by malleation, cause fuel oil
Liquid level reduces, fuel delivery deficiency, during so as to avoid engine from being again started up because fuel delivery deficiency and caused by start it is tired
Difficult phenomenon.
