Description

Fuel filter

[ technical field ] A method for producing a semiconductor device

The invention relates to the field of filters, in particular to a fuel filter.

[ background of the invention ]

The filter in diesel vehicle filters harmful impurity and moisture in the fuel oil system, protect the normal work of the engine, reduce the abrasion, avoid blocking, improve the engine life-span, the fluid is from the oil tank of the vehicle to the oil pump and high pressure supplies the rail system to generally pass through the two-stage filter, at present, the filter of the diesel vehicle only has filtration, the vehicle does not operate, some fluid in the fuel oil system flows to the direction of oil tank through oil pump and filter, the air gathers in the filter core in the filter, the air forms the big air current and carries the oil transfer pump position, when starting the engine again, the air produces the air lock in the oil transfer pump, the oil transfer pump is apt to idle running, lead to not supplying oil or supply amount too little, when the vehicle starts again, the engine is difficult to start, even started the operation is unstable, even if even by oneself flame-out.

The invention is provided for overcoming the defects of the prior art.

[ summary of the invention ]

The object of the present invention is to overcome the above-mentioned disadvantages of the prior art and to provide a fuel filter.

The invention can be realized by the following technical scheme:

the invention discloses a fuel filter, which comprises a shell, wherein an oil outlet pipe is fixed at the middle position of the upper end of the shell, an oil inlet is also fixed on the shell, a communicating pipe is fixed below the oil outlet pipe in the shell, a partition plate is fixed between the communicating pipe and the inner wall of the shell, a base is fixed at the upper end of the partition plate, a filter element is fixed on the base, a plurality of filter pipes are uniformly fixed in the filter element, spray pipes sleeved with the filter pipes are also fixed at the positions, corresponding to the filter pipes, on the partition plate, spray pipes below the partition plate are all fixed with atomizing nozzles, and a check valve matched with the oil outlet pipe is also fixed at the tail end of the communicating pipe. The oil is discharged into the shell through the oil inlet, the oil reaches the position of the filter pipe after being filtered by the filter element, the oil reaches the lower part of the partition plate after passing through the atomizer after passing through the filter pipe and the spray pipe, the filtered oil is discharged for use through the oil outlet pipe after passing through the check valve on the communication pipe again, after reaching the position of the filter element, the oil respectively enters the filter element through the inner wall and the outer wall of the filter element, the area of the oil entering the filter element is increased, the phenomenon that the surface of the filter element is blocked by the diesel oil to influence the filtering effect is avoided, and after air in the oil is gathered at the position of the filter element, large bubbles are formed and flow to the position of the atomizer along with the oil, under the action of the atomizer, the large bubbles are cut into small bubbles again and then are discharged along with the oil to be supplied to an engine for combustion, the phenomenon that the large bubbles are gathered to cause idling of the oil transfer pump can be effectively avoided, and when the oil supply is stopped, the oil flows back, the oil can be stored in the oil outlet pipe above the check valve, the phenomenon that the pipeline of the fuel system is full of gas due to fuel backflow is avoided.

Preferably, the cross section of the base is concave.

Preferably, the filter element is a torus structure.

Preferably, the check valve comprises a support fixed inside the communication pipe, a support rod connected with the support in a sliding manner is arranged on the support, a limiting plate is fixed at the bottom of the support rod inside the communication pipe, and an umbrella-shaped sealing cover is further fixed at the top of the support rod inside the oil outlet pipe. When the check valve is opened, oil pushes the sealing cover to be separated from the top of the communicating pipe, the oil can normally reach the oil outlet pipe, and when oil supply is stopped, oil backflow pushes the sealing cover to cover the top of the communicating pipe to seal the communicating pipe.

Preferably, the shell is internally and fixedly provided with a limiting seat clamped with the upper end of the filter element.

Preferably, a drain pipe is further fixed on the shell, one end of the drain pipe is arranged at the bottom in the shell, the other end of the drain pipe is arranged outside the shell, and a valve is further fixed on the drain pipe. The water in the oil is gathered at the bottom in the shell, the valve on the drain pipe is opened after a period of time, and the water in the shell is discharged through the drain pipe.

Compared with the prior art, the invention has the following advantages:

1. after fluid reachd the filter core position, fluid passes through filter core inner wall and outer wall respectively and gets into the filter core, has increased the area that fluid got into the filter core, avoids diesel oil to block up the phenomenon emergence that filter core surface influences the filter effect.

2. Air in the fluid is behind the filter core position gathering, forms big bubble and flows to the atomizer position along with fluid, through the atomizer effect, supplies with the engine burning along with fluid discharge after cutting into little bubble with big bubble once more, can effectively avoid big bubble gathering to lead to the phenomenon of fuel delivery pump idle running to take place.
