Abstract
The utility model relates to a fuel filter in favor of maintenance, which comprises an upper cover, a filtration core, a center tube and a shell body, wherein the upper cover and the filtration core are sleeved on the center tube as a whole after being connected, the shell body is respectively connected to the upper cover and the center tube, an oil return hole is disposed on the center tube, an oil return channel communicated with the oil return hole is disposed on the shell body and a lower sealing ring is disposed on the filtration core; and in an operation situation, the lower sealing ring seals the oil return hole on the center tube, the filtration core is moved upwards to drive the lower sealing ring to move upwards when replacement and maintenance are needed, and fuel inside the filter passes through the oil return hole and the oil return channel in order and then flows out when the oil return hole is opened. In comparison with the prior art, the fuel filter in favor of the maintenance in the utility model has the advantages of environmental protection, cost saving and easy operations etc.
Description
Technical field
The utility model relates to a kind of fuel filter, especially relates to a kind of fuel filter that is conducive to maintenance.
Background technique
At present, existing fuel filter product is changing when maintenance, and the fuel oil that fuel oil tends to be leaked in outside and fuel filter module can directly discard, not only befouling environment but also increase upkeep cost.Along with the requirement of environmental protection and reduction cost of upkeep is subject to social extensive concern, the novel maintenance mode that need to adapt with it day by day.
Model utility content
The purpose of this utility model is exactly the fuel filter that is conducive to maintenance that a kind of environmental protection, cost savings, convenient operation are provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fuel filter that is conducive to maintenance, comprise upper cover, filter core, center tube and housing, after described upper cover is connected with filter core, entirety is set on center tube, described housing is connected with upper cover and center tube respectively, it is characterized in that, described center tube is provided with return opening, and described housing is provided with the drainback passage being communicated with return opening, and described filter core is provided with lower seal circle;
When working state, described lower seal circle seals up the return opening on center tube, and in the time that needs are changed maintenance, described filter core moves up and drives lower seal circle to move up, return opening is opened, and the fuel oil in filter cleaner is successively by flowing out after return opening and drainback passage.
Described upper cover is connected by being clasped with filter core.
Between described upper cover and filter core, be provided with upper sealing gasket.
Described upper cover is connected with housing by screw thread.
Described center tube is connected with housing by screw thread.
Compared with prior art, the utlity model has following advantage:
1, environmental protection: avoid toppling over the oil in filter cleaner, reduced the pollution to environment.
2, cost savings: the oil in filter cleaner can recycle again after getting back to fuel tank, has saved expense.
3, convenient operation: simple to operate understandable, do not need special tool(s); , while taking-up from housing due to filter core, drain meanwhile, made operator be easier to operation, also guaranteed that operating environment do not polluted by oil product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Local structure for amplifying schematic diagram when Fig. 2 is normal working;
Local structure for amplifying schematic diagram when Fig. 3 maintains for changing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of fuel filter that is conducive to maintenance, comprise upper cover 1, filter core 2, center tube 3 and housing 4, after described upper cover 1 is connected with filter core 2, entirety is set on center tube 3, described housing 4 is connected with upper cover 1 and center tube 3 respectively, described center tube 3 is provided with return opening 31, and described housing 4 is provided with the drainback passage 41 being communicated with return opening, and described filter core 2 is provided with lower seal circle 21.
As shown in Figures 2 and 3, in fuel filter module routine, seal up the return opening 31 of center tube 3 by the lower seal circle 21 of filter core 2; In the time that filter core 2 is changed maintenance, rotation upper cover 1 upwards drives filter core 2 by being clasped between upper cover 1 and filter core 2, filter core 2 upper sealing gaskets still keep sealing, lower seal circle 21 is owing to moving upward, the return opening of center tube 3 31 is opened, and the fuel oil in filter cleaner is got back to fuel tank through the drainback passage 41 of housing 4 by return tube by the return opening 31 of center tube 3.By the time, after the oil in housing 4 flows away by drainback passage, take out upper cover 1 by being clasped with the fuel-displaced filter core having drained 2.Properly discard the filter core 2 of changing, change a new filter core 2 and and upper cover 1 by snap-fitted as sub-assembly, by tightening upper cover 1 after this sub-assembly screw-in housing 4, so just realized the function of clean maintenance.
Claims (5)
1. one kind is conducive to the fuel filter of maintenance, comprise upper cover, filter core, center tube and housing, after described upper cover is connected with filter core, entirety is set on center tube, described housing is connected with upper cover and center tube respectively, it is characterized in that, described center tube is provided with return opening, and described housing is provided with the drainback passage being communicated with return opening, and described filter core is provided with lower seal circle;
When working state, described lower seal circle seals up the return opening on center tube, and in the time that needs are changed maintenance, described filter core moves up and drives lower seal circle to move up, return opening is opened, and the fuel oil in filter cleaner is successively by flowing out after return opening and drainback passage.
