Abstract
The invention relates to a novel fuel filter and particularly relates to a double oil channel diesel filter with a clean oil suction type hand pump. According to the novel fuel filter, one end of the fuel inlet pipe is an oil inlet, the other end of the fuel inlet pipe is a tail end, a filter element is arranged between the oil inlet and the tail end, a pipeline is divided into two branches from the tail end of the fuel inlet pipe, a first branch is communicated with the lower portion of a hand pump body and then communicated with an oil outlet pipe, and a second branch is communicated with the oil outlet pipe. By means of double channel design of the fuel filter, initial pressure drop of the fuel filter is effectively reduced, and the service life of parts is prolonged.
Description
Technical field
The present invention relates to a kind of fuel filter, especially with the exhaustion oily formula hand pump two oil duct diesel-oil filters.
Background technique
The fuel filter that uses of car load much all is not to be with hand pump or with the hand pump of inhaling dirty oily formula in the market, and all be single pass, not with the fuel filter of hand pump after the low pressure oil way air inlet, the exhaust of necessary external hand pump ability, and with the fuel filter of inhaling dirty oily formula hand pump in use, can be too dirty because of oil product, cause the impurity in the fuel oil to be piled up at parts such as the piston of hand pump and one-way valves, thereby cause clamping stagnation, the failure modes such as poor sealing, affect the normal operation of each parts, cause hand pump to lose efficacy and cause that bavin combustion filter cleaner lost efficacy, vehicle can't run well.In addition based on diesel-oil filter assembly space restriction in some vehicle, common diesel-oil filter can't namely be considered to assemble satisfies again human engineering.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality needs, a kind of fuel filter is provided, especially with two oil duct diesel-oil filters of the oily formula hand pump that exhausts.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of fuel filter, fuel oil oil inlet pipe one end is filler opening, the other end is terminal, be provided with filter core between filler opening and the end, described pipeline is divided into two branch roads from the oil inlet pipe end of fuel oil, the first branch road be communicated with oil outlet tube again after the bottom of hand pump body is communicated with, the second branch road is communicated with oil outlet tube.
Two ends, described hand pump body bottom are respectively equipped with the first one-way valve and the second one-way valve, described the first branch road be communicated with oil outlet tube through the second one-way valve again after the first one-way valve is communicated with, described the second branch road is provided with the 3rd one-way valve.
Described hand pump is provided with bleeder screw.
The installation direction of described hand pump is vertical with direction of operating.
Beneficial effect of the present invention is:
1. the design of the Twin channel of fuel filter effectively reduces the initial drop of fuel filter, the working life of having improved each part;
2. the direction of operating of the hand pump design vertical with installation direction fully considered from the human engineering angle convenience of pump oil when novel diesel-oil filter is installed in the engine compartment left side, can directly carry out the operation of pump oil from the vehicle dead ahead.
Description of drawings
Fig. 1 is external structure schematic representation of the present invention;
Fig. 2 is that the hand pump fuel oil flows to schematic representation.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of fuel filter, fuel oil oil inlet pipe 6 one ends are filler opening 61, the other end is terminal 62, be provided with filter core 7 between the filler opening 61 and terminal 62, fuel pipe is divided into two branch roads from oil inlet pipe end 62, the first branch road be communicated with oil outlet tube 4 again after the bottom of hand pump housing 2 is communicated with, the second branch road directly is communicated with oil outlet tube 4.
Two ends, described hand pump housing 2 bottom are respectively equipped with the first one-way valve 8 and the second one-way valve 3, described the first branch road be communicated with oil outlet tube 4 through the second one-way valve 3 again after the first one-way valve 8 is communicated with, described the second branch road is provided with the 3rd one-way valve 5.
Hand pump 1 is provided with bleeder screw 9.
As larger improvements of the present invention, the installation direction of described hand pump 1 is vertical with direction of operating.
As shown in Figure 1, the operation planar of hand pump 1 is vertical fore side, its mounting plane is horizontal plane, therefore, its installation direction is vertical with direction of operating, such design, the abundant convenience of having considered pump oil from the human engineering angle, when novel fuel filter is installed in the engine compartment left side, can directly carry out the operation of pump oil from the vehicle dead ahead.
Use principle of the present invention is summarized as follows:
Fuel oil is flowed into by being divided into two branch roads behind the filter core 7 by filler opening 61, one the tunnel after the first one-way valve 8 flows into the hand pump body interior from an end of hand pump housing 2 bottoms the other end from hand pump housing 2 bottoms flow out through the second one-way valve 3, and flow out by oil outlet tube, the 3rd one-way valve 5 is flowed through afterwards from oil outlet tube 4 outflows in another road.
Guaranteed that the fuel oil that hand pump 1, hand pump housing 2, bleeder screw 9, heater 11 contact all is to filter clean product afterwards through filter core 7, and when the first one-way valve 8 and the second one-way valve 3 lost efficacy separately or simultaneously, fuel oil can arrive oil outlet tube 4 by the 3rd one-way valve 5, when the 3rd one-way valve 5 lost efficacy, fuel oil can arrive oil outlet tube 4 by the first one-way valve 8 and the second one-way valve 3, thereby the failure risk of reduce fuel oil filter cleaner, the assurance system still can normally move.And under normal circumstances, when namely two oil ducts are all worked, the pressure drop less of fuel filter of the present invention.
The Twin channel design of fuel filter effectively reduces the initial drop of fuel filter, the working life of having improved each part.The design that the direction of operating of hand pump is vertical with installation direction has fully been considered from the human engineering angle convenience of pump oil when novel diesel-oil filter is installed in the engine compartment left side, can directly carry out the operation of pump oil from the vehicle dead ahead.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
