Abstract
The utility model discloses a net type oil filter and relates to hydraulic systems. The net type oil filter comprises a shell, and a filtering element is arranged in the shell. An end cover is arranged above the shell, and a self-sealed valve is arranged below the shell. The type oil filter is characterized in that protruding blocks are arranged on the bottom side in the shell, and the protruding blocks are annularly and evenly distributed on the inner lateral face of the shell. An oil through net board is arranged on the protruding blocks in an erected mode. The net type oil filter is simple in structure and reasonable in design. A layer of the oil through net board is additionally arranged in rear of a strainer, and oil undergoes secondary filtering after passing through the strainer. The net type oil filter is capable of improving the filtering precision, simple and practical, the oil through net board is directly arranged on the protruding blocks in the erected mode, and replacing and cleaning the oil through net board are facilitated.
Description
Technical field:
The utility model relates to hydraulic system, is specifically related to a kind of screen filter.
Background technique:
Screen filter, its filter core be take copper mesh as filtering material, has around on the plastics or metal cylindrical skeleton in a lot of holes, is wrapping one deck or two-layer copper mesh, and its filter precision depends on the size of the copper mesh number of plies and mesh.This oil filter structure is simple, and through-current capability is large, easy to clean, but filter precision is low, is generally used for the inlet port of oil hydraulic pump.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, and the screen filter that a kind of filter precision is high is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of screen filter, comprise housing, is provided with filter core in housing, the housing top is provided with end cap, and the housing below is provided with Self-sealing valve, and it is characterized in that: described enclosure interior bottom side is provided with projection, projection is uniformly distributed along housing inner side surface annular, sets up the logical web plate of oil on projection.
Described projection is provided with groove, and the logical web plate grid beam of oil is located in groove, makes the logical web plate of oil more stable.
Be provided with U magnet in described groove, U magnet not only can set up by the logical web plate grid of fuel feeding, and can the logical web plate of oil be adsorbed on projection with suction, makes structure more stable.
The utility model is simple in structure, reasonable in design, sets up the logical web plate of one deck oil after filter screen, and oil is filtering for the second time at the laggard row of process filter screen, improves filter precision, simple and practical, and the logical web plate of oil directly is erected on projection, and convenient taking-up is changed and cleaned.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: housing; 2: filter core; 3: end cap; 4: Self-sealing valve; 5: projection; 6: the logical web plate of oil; 7: groove; 8:U shape magnet.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of screen filter as shown in Figure 1, comprise housing 1, be provided with filter core 2 in housing 1, housing 1 top is provided with end cap 3, and housing 1 below is provided with Self-sealing valve 4, its inner bottom side of middle shell 1 is provided with projection 5, projection 5 is uniformly distributed along housing 1 inner side surface annular, sets up the logical web plate 6 of oil on projection 1, and wherein projection 5 is provided with groove 7, be provided with U magnet 8 in its further groove 7, logical web plate 6 grid beams of oil are located in the U magnet 8 in groove 7.
Above demonstration and described basic principle of the present utility model, 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; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
