Abstract
The utility model relates to a novel fuel filter, in particular to a double-oil-duct diesel oil filter provided with an oil-suction-type hand pump. According to the novel fuel filter, an oil inlet is formed in one end of a fuel inlet pipe, the other end is a tail end, and a filter core is arranged between the oil inlet and the tail end; the pipeline is divided into two branches from the tail end of the fuel inlet pipe; a first branch is communicated with the lower part of a hand pump body and then is communicated with an oil outlet pipe; and a second branch is directly communicated with the oil outlet pipe. The double-channel design of the fuel filter effectively reduces the initial pressure drop of the fuel filter and prolongs the service lives of all parts.
Description
Technical field
The utility model relates to a kind of novel fuel filter cleaner, especially has two oil duct diesel-oil filters of the oily formula hand pump that exhausts.
Background technique
The fuel filter of car load use in the market much all is not to be with hand pump or to have the hand pump of inhaling dirty oily formula, and all be single pass, not with the fuel filter of hand pump after the air inlet of low pressure oil circuit, the exhaust of necessary external hand pump ability, and have inhale dirty oily formula hand pump fuel filter 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, failure modes such as poor sealing, influence the proper functioning 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 human engineering again.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to the reality needs, and a kind of novel fuel filter cleaner is provided, and especially has two oil duct diesel-oil filters of the oily formula hand pump that exhausts.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of novel fuel filter cleaner, 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, pipeline is divided into two branch roads from the oil inlet pipe end of fuel oil, first branch road be communicated with oil outlet tube again after the bottom of hand pump body is communicated with, second branch road directly is communicated with oil outlet tube.
Two ends, described hand pump body bottom are respectively equipped with first one-way valve and second one-way valve, described first branch road be communicated with oil outlet tube through second one-way valve again after first one-way valve is communicated with, described 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.
The beneficial effects of the utility model are:
1. the design of the Twin channel of novel fuel filter cleaner 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 utility model;
Fig. 2 flows to schematic representation for the hand pump fuel oil.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of novel fuel filter cleaner, 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 terminal 62, first branch road be communicated with oil outlet tube 4 again after the bottom of hand pump housing 2 is communicated with, second branch road directly is communicated with oil outlet tube 4.
Two ends, described hand pump housing 2 bottom are respectively equipped with first one-way valve 8 and second one-way valve 3, described first branch road be communicated with oil outlet tube 4 through second one-way valve 3 again after first one-way valve 8 is communicated with, described second branch road is provided with the 3rd one-way valve 5.
Hand pump 1 is provided with bleeder screw 9.
As bigger improvements of the present utility model, 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 utility model 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 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 second one-way valve 3, and flow out by oil outlet tube, the 3rd one-way valve 5 backs are flowed through 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 first one-way valve 8 and 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 first one-way valve 8 and second one-way valve 3, thereby reduce the failure risk of fuel filter, the assurance system still can normally move.And under normal circumstances, when just two oil ducts were all worked, the pressure drop of fuel filter of the present utility model was less relatively.
The Twin channel design of novel fuel filter cleaner 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 embodiment of the present utility model announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
