Abstract
The utility model discloses a diesel oil filter which comprises a diesel oil filter element end cover (16), a filter element assembly (7), a water release valve assembly (5), an outer shell (6) and a screw plate (9). Upward protrusions (15) are arranged on the circumferential wall of the diesel oil filter element end cover. Guide holes (2) are formed in the protrusions. Concave grooves (4) are formed in upper ends of the protrusions. First internal sealing pieces (3) are arranged in the concave grooves and between the diesel oil filter element end cover and the screw plate. When diesel oil goes through the guide holes of the diesel oil filter element end cover and is guided, the small guide holes play a role of capillary tubes. Emulsifying water in the diesel oil is separated into free water according to the difference of the specific gravity of oil and the specific gravity of water. Due to the fact that free water is larger than emulsifying water in free degree, the free water can be separated automatically, so that the overall oil-water separating efficiency of the filter is improved, the service life of the filter is prolonged, and the quality of the filter is improved.
Description
Technical field
The present invention relates to a kind of Vehicular cleaner, specifically relate to a kind of diesel-oil filter.
Background technique
At present, the filter core assembly of diesel-oil filter comprises filter paper, center tube, end cover of filter element, and its end cover of filter element is common ferrous material, there is no special structural design, only can play a supporting role to the filter paper in filter core assembly, not possess the oil-water separating function for diesel oil.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of its diesel-oil filter element end cap to there is the diesel-oil filter of good oil-water separation effect.
The object of the invention realizes by the following technical solutions: diesel-oil filter, comprise diesel-oil filter element end cap, element kit, discharging valve assembly, shell, spiral shell plate, the perisporium of described diesel-oil filter element end cap has projection upwards, in this projection, be provided with pod apertures, upper end in this projection is provided with Baltimore groove, locates to be equipped with the first interior confidential paper in this Baltimore groove and between diesel-oil filter element end cap and spiral shell plate.
Adopt after the present invention, when diesel oil passes through the pod apertures water conservancy diversion on diesel-oil filter element end cap, these small pod apertures have played the effect of " capillary tube ", according to oil, water proportion difference, eccentricity when the oil in diesel oil, water are through pod apertures is also different, thereby the emulsified water in diesel oil is separated into free water, because the degrees of freedom of free water is greater than emulsified water, this part free water can be separated automatically, thereby improved the oil-water separation efficiency of filter cleaner integral body, extend the working life of filter cleaner, promoted the quality of filter cleaner product.
Accompanying drawing explanation
Fig. 1 is the diesel-oil filter element end cover structure schematic diagram of diesel-oil filter of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the structural representation of diesel-oil filter of the present invention.
Embodiment
By accompanying drawing and mode of execution, the present invention is described in further detail below.
Known with reference to Fig. 1, Fig. 2, be applied to the diesel-oil filter element end cap of diesel-oil filter, comprise end cap body 1, the material of described end cap body 1 is engineering plastics, the perisporium of described end cap body 1 has projection 15 upwards, in this projection 15, be provided with pod apertures 2 (several), in the upper end of this projection 15, be provided with Baltimore groove 4 (for placing the first interior confidential paper 3 of diesel-oil filter).The material of described end cap body 1 is engineering plastic nylon 66 (but not limiting to), as long as meet the mechanical property of filter cleaner, requires.
Known with reference to Fig. 3, diesel-oil filter of the present invention, comprise diesel-oil filter element end cap 16 (being end cap body 1), element kit 7 (comprising filter paper, center tube), discharging valve assembly 5, shell 6, spiral shell plate 9 (and seal ring 12, sealing ring fixed plate 10), the perisporium of described diesel-oil filter element end cap 16 has projection 15 upwards, in this projection 15, be provided with pod apertures 2 (several), in the upper end of this projection 15, be provided with Baltimore groove 4, in this Baltimore groove 4 and between diesel-oil filter element end cap 16 and spiral shell plate 9, locate to be equipped with the first interior confidential paper 3.
Wherein, the material of described diesel-oil filter element end cap 16 is engineering plastics, the second interior confidential paper 11 is equipped with at place, left side between described diesel-oil filter element end cap 16 and spiral shell plate 9, in described shell 6 and between shell 6 and element kit 7, locate to have the diesel oil of filtration passage 13, on described spiral shell plate 9, there is filler opening 8, oil outlet 14.
The working principle of this diesel-oil filter (and end cover of filter element) is: do not filter diesel oil and entered after this filter cleaner by the filler opening 8 on spiral shell plate 9, sealing due to confidential paper in first, second, do not filter diesel oil the pod apertures by diesel-oil filter element end cap 16 2 is flowed into and do not filtered in diesel oil passage 13, then filter by the oil outlet 14 on spiral shell plate 9 and flow out by element kit 7.When diesel oil process pod apertures 2 water conservancy diversion, these small pod apertures 2 have played the effect of " capillary tube ", according to oil, water proportion difference, eccentricity when the oil in diesel oil, water are through pod apertures 2 is also different, thereby the emulsified water in diesel oil is separated into free water, because the degrees of freedom of free water is greater than emulsified water, free water is with respect to emulsified water, be easy to from diesel oil separated, this part free water can flow into discharging valve assembly 5 along the inwall of shell 6 and emit, and has improved the whole oil-water separation efficiency of filter cleaner.
Claims (1)
1. diesel-oil filter, comprise diesel-oil filter element end cap (16), element kit (7), discharging valve assembly (5), shell (6), spiral shell plate (9), it is characterized in that: the perisporium of described diesel-oil filter element end cap (16) has projection (15) upwards, in this projection (15), be provided with pod apertures (2), in the upper end of this projection (15), be provided with Baltimore groove (4), in this Baltimore groove (4) and between diesel-oil filter element end cap (16) and spiral shell plate (9), locate to be equipped with the first interior confidential paper (3).
