Abstract
The utility model discloses a rotary type diesel oil filter which comprises a casing; a central pipe is arranged in the casing; a filter element is arranged on the central pipe in a jacketing manner; a filter element baffle plate is arranged at the lower end of the filter element and is clamped on the casing; a filter element upper cover is arranged at the upper end of the filter element and comprises a positioning cover, a connecting cover and a seal ring; the positioning cover is welded on the inner end surface of the connecting cover; the seal ring is arranged on the outer end surface of the connecting cover; the connecting cover and the seal ring are riveted through a punch press; a central connection screw hole and an oil inlet are formed in the connecting cover; a ring-shaped clamping groove is formed on the outer end surface of the seal ring; and a sealing ring is mounted in the ring-shaped clamping groove. After the structure is adopted, the sealing ring mounted in the ring-shaped clamping groove on the seal ring can effectively prevent oil at the oil inlet of the connecting cover from flowing back, so that the integral leak tightness of the diesel oil filter can be improved, and the diesel oil filter can be used more safely and more reliably.
Description
Technical field
The utility model relates to a kind of diesel fuel filter, is specifically related to a kind of rotation fitting type diesel fuel filter.
Background technology
At present, diesel fuel filter common on the market mainly comprises shell, is provided with central tube in the shell; Be arranged with filter core on the central tube, the axial upper/lower terminal of filter core is provided with filter core loam cake and filter core lower cover, covers on the filter core to be provided with the outside center that is connected to connect screw; Cover on the filter core and also be provided with oil-in; Because the filter core loam cake is not provided with corresponding sealing device outward, thereby causes the backflow of oil-in place profit easily, bring hidden danger for the safe handling of diesel fuel filter.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rotation fitting type diesel fuel filter safer, that sealing property better, production cost is lower that uses.
For realizing above-mentioned purpose, the utility model provides a kind of rotation fitting type diesel fuel filter, comprises shell; Be provided with central tube in the shell, be arranged with filter core on the central tube, the lower end of filter core is provided with the filter core dividing plate; Described filter core dividing plate is installed on the shell, and the upper end of filter core is provided with the filter core loam cake, and described filter core loam cake is made up of location lid, connection cover, seal ring; The lid weldering of described location is located on the connection cover inner face, and the outer face of connection cover is provided with seal ring, and described connection cover and seal ring are through the punch press riveted; Connection cover is provided with the center and connects screw and oil-in, and the outer face of said seal ring is provided with the ring-type draw-in groove, is equiped with sealing ring in the ring-type draw-in groove.
The beneficial effect of the utility model is: adopt said structure; Because the filter core loam cake that the filter core upper end is provided with is made up of location lid, connection cover, seal ring; Location lid weldering is located on the connection cover inner face, and the outer face of connection cover then is provided with seal ring, and the outer face of said seal ring is provided with the ring-type draw-in groove; Be equiped with sealing ring in the ring-type draw-in groove; Therefore can prevent the backflow of the enterprising oil port profit of connection cover effectively, improve the overall tightness of diesel fuel filter, make the use of diesel fuel filter safer reliable.
The utility model can further be set to described filter core and rolled by filter paper and form, filter core and filter core dividing plate, and filter core and central tube between fix through binding agent.
Adopt said structure; Described filter core is rolled by filter paper and forms, and filter core and filter core dividing plate, and filter core and central tube between fix through binding agent, such structure setting makes that not only the making of filter core is comparatively simple; Can save production cost; And, therefore can significantly improve filter effect because the area coverage of coil paper is wide, and the ply of paper integral density is big.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1ly provide a kind of rotation fitting type diesel fuel filter, comprised shell 1, be provided with central tube 2 in the shell 1; Be arranged with filter core 3 on the central tube 2, the lower end of filter core 3 is provided with filter core dividing plate 4, and described filter core dividing plate 4 is installed on the shell 1; The upper end of filter core 3 is provided with the filter core loam cake; Described filter core loam cake by the location cover 5, connection cover 6, seal ring 7 constitute, described location lid 5 welds to be located on connection cover 6 inner faces, the outer face of connection cover 6 is provided with seal ring 7; Described connection cover 6 passes through the punch press riveted with seal ring 7; Connection cover 6 is provided with the center and connects screw 61 and oil-in 62, and the outer face of said seal ring 7 is provided with ring-type draw-in groove 71, is equiped with sealing ring 8 in the ring-type draw-in groove 71.Since the filter core loam cake that filter core upper end is provided with by the location cover 5, connection cover 6, seal ring 7 constitute; The location cover 5 and is welded and to be located on connection cover 6 inner faces, and the outer face of connection cover 6 then is provided with seal ring 7, and the outer face of said seal ring 7 is provided with ring-type draw-in groove 71; Be equiped with sealing ring 8 in the ring-type draw-in groove 71; Therefore can prevent the backflow of oil-in 62 place's profits on the connection cover 6 effectively, improve the overall tightness of diesel fuel filter, make the use of diesel fuel filter safer reliable.In addition, described filter core 3 is rolled by filter paper and forms, and filter core 3 and filter core dividing plate 4, reaches between filter core 3 and the central tube 2 and fixes through binding agent.Such structure setting makes that not only the making of filter core 3 is comparatively simple, can save production cost, and because the area coverage of coil paper is wide, and the ply of paper integral density is big, therefore can significantly improve filter effect.
