Abstract
The utility model provides a fuel filter with valve drains, includes shell, its characterized in that: the enclosure component upper end is provided with thread cover plate, 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, the thread cover plate below is provided with the non return valve block, be provided with filter paper in the shell, filter paper is wrapping up the center tube, supporting spring is connected to the center tube lower extreme, the shell lower extreme is provided with the drain nut and the valve that drains. The utility model relates to a rationally, compact structure, filtration efficiency is high, sealing performance is good, can avoid causing 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 to set up the non return valve block, more strengthened the leakproofness, made the filter effect better, set up the turn on the water valve and the nut that turns on the water simultaneously, made things convenient for the filter to turn on the water when using.
Description
Technical field:
The utility model relates to filter cleaner technical field, particularly relates to a kind of fuel filter with discharging valve.
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 with discharging valve of good seal performance.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of fuel filter with discharging valve, comprise shell, it is characterized in that: described case member upper end is provided with thread plate, described thread plate is provided with sealing ring fixed plate, described sealing ring fixed plate is fixed with seal ring, below described thread plate, be provided with non-return valve block, filter paper is provided with in described shell, described filter paper is wrapped in center tube, and lower end, described center tube lower end connects supported spring, and described shell lower end is provided with water-discharging nut and discharging valve.
Be provided with multilayer insulating panel in described center tube, described dividing plate is provided with multiple through hole.
Described filter paper upper end is provided with refill upper cover, and lower end is provided with refill lower cover.
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, and be provided with non-return valve block, more strengthen sealing, make filtering effect better, be provided with discharging valve and water-discharging nut simultaneously, facilitate filter cleaner to discharge water in use.
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 with discharging valve, comprise shell 1, described shell 1 component upper ends is provided with thread plate 2, described thread plate 2 is provided with sealing ring fixed plate 3, described sealing ring fixed plate 3 is fixed with seal ring 4, non-return valve block 5 is provided with below described thread plate 2, filter paper 6 is provided with in described shell, described filter paper 6 is wrapped in center tube 7, lower end, described center tube 7 lower end connects supported spring 8, described shell 1 lower end is provided with water-discharging nut 9 and discharging valve 10, multilayer insulating panel 11 is provided with in described center tube 7, described dividing plate 11 is provided with multiple through hole 12, described filter paper 6 upper end is provided with refill upper cover 13, lower end is provided with refill lower cover 14.
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.
