Abstract
The utility model provides a fuel filter of fixed filter paper, includes shell, its characterized in that: the enclosure component upper end is provided with thread cover plate, thread cover plate is the unevenness form, the thread cover plate center is provided with the arc open -ended water conservancy diversion mouth that makes progress, the last sealing ring fixing plate that is provided with of thread cover plate, the last sealing washer that is fixed with of sealing ring fixing plate, be provided with the refill upper cover under the thread cover plate, be fixed with filter paper under the refill upper cover, the enclosure component lower extreme is provided with the nut that drains. The utility model relates to a rationally, compact structure, filtration efficiency is high, sealing performance is good, can avoid leading to the fact engine early wear with carrying out effective filtering to the impurity that the engine is harmful in the fuel, and the sealing washer is combined closely with sealing ring fixing plate, has more strengthened the leakproofness, and the filter paper top has set up the refill upper cover simultaneously, makes filter paper fixed more firm, prevents that filter paper from sliding in the shell, makes the filter effect better.
Description
Technical field:
The utility model relates to filter cleaner technical field, particularly relates to the filter cleaner that a kind of decreasing pollution enters.
Background technique:
Motor has air, machine oil, fuel oil three kinds of filter cleaners, is generally called " three filters ".They undertake the filtration of engine aspirating system, lubrication system and combustion system medium respectively.
The effect of fuel filter is deleterious particle in filtering engine fuel gas system and moisture content, to protect oil pump nozzle, cylinder sleeve, piston ring etc., reduces wear, avoids blocking.Solid sundries removings such as the iron oxide be contained in fuel oil, dust, prevent oil-fired system from blocking (particularly oil nozzle).Reduce mechanical wear, guarantee that engine stabilizer runs, improve reliability.
Even if diesel oil have passed through precipitation and filters before adding diesel oil tank, clean, but in refueling process, because fueling vehicle, oiling circumstance, reservoir port be unclean etc., factor still can make contaminated by diesel oil, and in diesel engine operation process, due to the impurity deposited in oil-fired system, the heavy dust suspended in air, also can make contaminated by diesel oil, therefore the diesel-oil filter on car is absolutely necessary, in addition diesel oil might not be real clean before adding fuel tank.
The structure of fuel filter is made up of the support of stainless steel in an aluminum hull and one, and support is equipped with high-efficient filter scraps of paper composition, and filter paper becomes cosmos, to increase circulation area.At present, the impurity harmful to motor, because its filter paper aperture is large, lack of homogeneity, filter efficiency are low, can not be carried out effective filtering, cause motor premature wear by traditional groove-fastening type fuel filter.Sealing oil resistance is poor, cannot ensure sealing.
Model utility content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides that a kind of filter efficiency is high, the fuel filter of the fixing filter paper of good seal performance.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of fuel filter of fixing filter paper, comprise shell, it is characterized in that: described case member upper end is provided with thread plate, described thread plate is roughness, and described thread plate center is provided with the flow-guiding mouth of arc upward opening, and described thread plate is provided with sealing ring fixed plate, described sealing ring fixed plate is fixed with seal ring, described thread plate is arranged with refill upper cover, is fixed with filter paper under described refill upper cover, and described case member lower end is provided with water-discharging nut.
Described sealing ring fixed plate one end is winding shape, is buckled in shell edge, and one end is provided with fixing button and thread plate is fixed.
Described sealing ring fixed plate is provided with groove, and described seal ring is fixed in groove, fits tightly with sealing ring fixed plate.
Described refill upper cover is fixed on thread plate by fixing button.
The utility model is reasonable in design, compact structure, filter efficiency is high, good seal performance, impurity harmful to motor in fuel oil can be carried out effective filtering, avoid causing motor premature wear, seal ring and sealing ring fixed plate are combined closely, more strengthen sealing, be provided with refill upper cover simultaneously above filter paper, what filter paper was fixed is more firm, prevent filter paper from sliding in the enclosure, make filtering effect better.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of fuel filter of fixing filter paper, comprise shell 1, described shell 1 component upper ends is provided with thread plate 2, described thread plate 2 is in roughness, described thread plate 2 center is provided with the flow-guiding mouth 3 of arc upward opening, described thread plate 2 is provided with sealing ring fixed plate 4, described sealing ring fixed plate 4 is fixed with seal ring 5, described thread plate 2 is arranged with refill upper cover 6, described refill upper cover is fixed with filter paper 76 times, described shell 1 lower is provided with water-discharging nut 8, described sealing ring fixed plate 4 one end is winding shape, be buckled in shell 1 edge, one end is provided with fixing button 9 and fixes with thread plate 2, described sealing ring fixed plate 4 is provided with groove 10, described seal ring 5 is fixed in groove 10, fit tightly with sealing ring fixed plate 4, described refill upper cover 6 is fixed on thread plate 2 by fixing button 9.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
