Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an oil-water separator structure. Background Art

[0002] Diesel fuel supply requires high standards of quality control, therefore, fuel filters are generally installed in the delivery pipeline for filtration. It is not uncommon for diesel fuel to be present in the form of impurities and water. Impurities can potentially permanently damage fuel injection pump components, easily destroying the fuel injection pump's ability to accurately meter fuel and deliver fuel at high pressures and adversely affecting pump performance. The presence of water can cause engine parts to rust, and in severe cold conditions, can cause interruptions in the fuel injection system and / or seizure of moving components.

[0003] Conventional fuel filters perform the dual function of removing particulate material from diesel fuel and separating water from the fuel. Typically, fuel filters utilize replaceable filter cartridges that are replaced at predetermined installation intervals during the filter's use. When the filter is installed into a fuel line where the fuel pressure is relatively high, the internal pressure capacity of the filter needs to be considered. Utility Model Content

[0020] As a further configuration of the above solution, the sealing member 7 is clamped and sleeved on the guide sleeve 35 and the guide tube 36 respectively, so as to fix the guide sleeve 35 and the guide tube 36 and prevent the medium from flowing.

[0021] As a further configuration of the above solution, the filter element 4 includes a folded filter paper layer 42 and an inner core sleeve 43 , and the inner core sleeve 43 is provided with filter holes.

[0022] As a further configuration of the above scheme, a drain valve assembly 8 is further provided on the housing 1 , and the drain valve assembly 8 includes a fixing seat 81 , a fixing screw cover 82 and a sealing ring 83 , and an eccentric driving column 84 is also provided on the fixing screw cover 82 .

[0023] As a further configuration of the above scheme, a U-shaped buckling portion 15 is extended between the filter cup cover 6 and the shell 1, and a threaded cap 14 is also sleeved on the shell 1. The threaded cap 14 is provided with an inner step ring 13, and the inner step ring 13 is arranged to abut against the buckling portion 15.

[0024] like Figure 1-4The oil-water separator structure of the present embodiment is cup-shaped as a whole. The two ends of the shell 1 are respectively provided with a flow channel cover 3 with an inlet hole 31 and an outlet hole 32, and the other end is provided with a drain valve assembly 8. The inlet hole 31 and the outlet hole 32 of the flow channel cover 3 are marked with in and out settings respectively to distinguish them. An inner flow channel 33 is also provided in the flow channel cover 3 for medium circulation. The flow channel cover 3 is provided with a guide tube 36, a guide sleeve 35 and a guide member 34 in sequence from the outside to the inside relative to the inner flow channel 33. The guide tube 36 and the guide sleeve 35 are installed by a seal 7 to achieve medium circulation isolation, such as Figure 2 As shown, during filtration, the medium will flow into the oil-water separator from the inlet flow channel hole 31, and will be connected to the inner cavity between the guide tube 36 and the guide sleeve 35 based on the inlet flow channel hole 31, and the inner cavity between the guide tube 36 and the guide sleeve 35 will be connected to the inner cavity of the filter cup cover 6. Therefore, after the medium enters the inlet flow channel hole 31 from the outside, it will enter the filter cup cover 6 based on the inner cavity between the guide tube 36 and the guide sleeve 35, and flow into the housing 1 from the outside of the filter 2 into the inner hole of the hollow cylindrical filter 2, and then enter the outlet flow channel hole 32 along the guide member 34;

In addition, the filter cup cover 6 and the housing 1 are extended to form a U-shaped buckling portion 15, and the housing 1 is also sleeved with a threaded cap 14, and the threaded cap 14 is provided with an inner step ring 13, and the inner step ring 13 is arranged to abut against the buckling portion 15;

[0026] In addition, in order to facilitate the replacement of the filter element 4, the present embodiment also adopts a filter cup cover 6 that is engaged and sealed with the housing 1 and is clamped and fixed by the housing 1 and the flow channel cover 3, so that the filter element 4 can be quickly replaced by rotating the threaded cap 14;

[0027] It is worth noting that Figure 3 The top of the filter cup cover 6 of the present embodiment shown is configured as a multi-section folding top cover, and as shown in FIG. Figure 4 The filter cover 5 shown is provided with a plurality of support members 51, and abuts against the inner top wall of the filter cup cover 6. The support members 51 and the filter cover 5 are fixed by gluing. This structural design can effectively reduce the sealing problem and the connection strength problem between components under high pressure environment. The multi-section folded top cover is matched with the filter cover 5 design to improve the strength, which can also help to extend the life of the filter to a certain extent.

[0028] Preferably, the seal 7 is a double-layer annular bell-mouth structure, and a double inclined step is arranged along the installation direction of the guide sleeve 35 or the guide tube 36. The minimum inner hole of the seal 7 is smaller than the outer diameter of the guide sleeve 35 or the guide tube 36. The seal 7 is clamped and sleeved on the guide sleeve 35 and the guide tube 36 respectively, and is used to fix the guide sleeve 35 and the guide tube 36 and seal the flow of the medium.
